What's New At O'Donnell & Associates, Inc.

February 15, 2018

Received word today that my favorite brother-in-law Jack McCoy passed away.  We just had the pleasure of attending his daughter Jenny's wedding in Brooklyn New York two weeks ago.  Tempus fugit, rest in peace Jack. Condolences to Patty, Keven, Jenny, Jenn, Abbie, John Grady, Amy and Guilherme.  God bless you all.  A tribute to Jack can be found at:


February 3, 2018

Made a tirp to New York City and Brooklyn for my neice's wedding.  Great time and the new couple are a perfect match.  Best wishes to Jenny and Guilherme deOliveira. 

January 25, 2018

Nell and I are pleased to welcome George Joseph, our newest grandson, to our family.  George is the son of Sam and Maggie O'Donnell.  

December 27, 2017

It's been a fast year but a good year and OAI hopes your year was equally good.  We've earned some new clients, welcomed back some old clients and teamed with some new engineering firms on some public supply well projects that should prove both challenging and interesting. 

Our research has opened possibilities for a new client and offered possibilities to another client.  Our groundwater level monitoring program identified a critical issue with one of our client's wells that left alone could have had catastrophic results but allowed them the chance to make corrections before damage was done.  

All in all, it has been a good year and we look forward to 2018 being a great year!

God Bless you all,

Dan and Nell 

October 27, 2017 OAI Welcomes CDG Engineers

Today, CDG became the 24th engineering client to contract OAI for professional hydrogeologic services on a project OAI completed earlier work for back in 2009.  The project involves consutling , field services and sourcewwater assessment services for a south Alabama utility's new well.  To date, OAI has been involved with planning, siting, developing, protecting or managing over 79 public supply wells including permitting 45 new wells.  We welcome CDG and, as always, work to provide them the same quality services we provide all our clients.

October 10, 2017 OAI's sourcewater work pays dividends

One of our municipal clients called today with growing concerns on the development of their next well.  Tentativel plans centered on a 1998 test well that had favorable results but they had difficulty securing the land needed to complete the production well.  This led them to retain OAI in 1999 to quickly locate a favorable site for developing a new well.  We did and they got that new well.

Fast forward to October 10th and once again, they called OAI with the same issue relating to that 1998 test well.  While at first they had favorable talks with securing the land at the test well site, things fell apart.  OAI was asked to "quickly" help them locate a new site.  By early the next morning, a field survey was completed on two potential locations identified based on OAI's 1999 sourcewater effort.  One proved bad while the other was extremely favorable.  A Scope of Work was agreed upon and implemented that found the potential site was in fact a highly probable site both production wise and water quality wise.  

Currently, plans are being underway to the development a production well at the site.

September 6, 2017 Happy Birthday Well #10

Just about this time ten years ago, OAI completed work on Well #10 for a local utility.  Well #10 is part of the third wellfield OAI planned, tested and permitted using our hydrogeologic method of developing groundwater resources.  The benefits of this method outlined at the time were as follows:

               1)  No off-site land purchase required for this wellfield as the City owns the property under consideration
               2)  Reduced piping cost (estimated at $18 to $30/foot)
               3)  Reduced treatment costs (new treatment plant will be sized to handle additional volume eliminating   costs associated with a stand alone plant)
               4)  Eliminate exploration costs (the aquifer has known water quality and production potential allowing the City  to forego “test wells”)

               Hydraulically and economically, the development of a wellfield at the exisitng wellsite make sense.  It's only money.

July 13, 2017 Welcome The Constantine Group

Today, The Constantine Group became the 23rd engineering firm to utilize OAI for hydrogeologic services for a mid-Alabama utility client of theirs in need of redundantcy for their public water supply.  The project will involve planning, testing and permitting a second well for the water system.  As a side note, a good side note, the water system becomes the 44th public water system to benefit from OAI's training and experience.  Welcome to both. 

July 12, 2017

White Houuse Water System's Well #1 went fully on-line today.  This, as noted in several notes below, is the system's first well which will serve to greatly reduce their purchased water costs.  Congrats to WHWS and thanks for selecting OAI for your hydrogeologic services.

June 5, 2017

Back to drilling at a location in north Baldwin County to evaluate potential by-passed production at a well originally drilled for another water system.  Due to continuous rain, OAI's field office required use of the  official OAI canopy, seen below, for the first time in two years.  If successful, water supplied from the new well will replace water requiring significant post-production treatment for the initial well.

May 19, 2017

Great day at OAI today.  First, on this day in 1999, we officially opened our doors as O'Donnell & Associates with a lot of prayers and a unique service.  We are thankful for all our clients who have placed their trust in our company.  Since 1999, OAI has provided hydrogeologic services on 70 test wells, 14 industrial supply wells, 4 irrigation wells, 79 public supply wells, completed 87 hydrogeologic studies, geologically logged 53,030 feet of well bores, complete 76 aquifer tests, 20 pumping tests, completed 80 groundwater modeling projects, developed wells capable of supplying a total of 36,234 gpm including 22,040 for public supply purposes and permitted 45 wells.   To you our clients, again, thank you and God bless you and your systems.

Second, we received a contract with our second oldest client to investigate by-passed production at one of their wellsites.  After a "geologic" absence of eight years, we are more than happy we have this system back as an OAI client.  With several well projects on the board, we look forward to many more years working with them to bring public supply water to their customers.

April 17, 2017

Stopped in at White House Water System today to complete the Public Awareness requirement of  their sourcewater assessment program.  While there, took this photo, seen above, of their new treatment plant for Well #1.  Expected to be online soon, Well #1 will reduce their purchased water cost by close to 63 percent.  Saving will be applied to system upgrades and a future well that will make them self sufficient.              

April 10, 2017

Began wellsite services on a backup groundwater sourced supply for a confidential client.  The back up water supply was required in the event the facility's primary source of public supply was interrupted.  The pilot boring was completed to a depth of 375 feet based on a hydrogeologic review OAI completed in 2011.  Two significant and promising sand aquifers were cut.  The sand correlated to a nearby irrigation well was targeted for development based on correlation to a nearby irrigation well that was sampled with favorable water quality in the 2011 review.  Of interest on this project was the change in color of the drilling mud as we drilled out of the Citronelle Formation (orange mud stream) into the Miocene Formation (gray mud stream) as seen in the photo below.

Chuck Barris of The Gong Show fame died today.  I named my college dog after him and enjoyed his show especially Gene Gene the Dancing Machine.  RIP Chuck.

February 13, 2017

Over the past years OAI has been called on to evaluate pumping test or aquifer test data where the well or wells are completed with their screens set in two separate aquifers.  While aquifer hydraulics can be evaluated if the testing isolates each individual aquifer such that the drawdown and recovery from that single aquifer can be monitored, none of the tests OAI was asked to evaluate were done in this manner.  As a rule, OAI won't provide an evaluation of the drawdown and recovery when two or more aquifers are screened and supply water to a single well (pumped well alone or pumped well and observation well).  In the book Applied Hydrogeology, Fourth Edition, C. W. Fetter (the author) summed our reason not to perform these evaluations nicely on page 212 stating:

Observation wells should also not be screened in aquifers other than the one in which the pumping well is also screened.  The author has seen cases where very expensive pumping tests yielded meaningless results because either the pumping well or the observation well was screened in more than one aquifer.  Time-drawdown data can be obtained from such misbegotten wells, and misguided hydrogeologists have attempted to evaluate them,  The results, however are garbage.

OAI has seen similar test evaluations.  On a side note, OAI recommends against screening aquifers in more than one aquifer, call to find out why.

January 2, 2017 Groundwater Monitoring

OAI initiated groundwater level monitoring at two more public supply wells as part of this client's long term management planning.  The data collected from this program will provide them with critical information on the health of their aquifers allowing them to better plan their next well or wells as the need arises.  On similar projects for other OAI clients, we have used the information to:

  • 1) support the position that aquifers in coastal Alabama are not being over produced,
  • 2) saved hundreds of thousands of dollars in exploration costs for our clients,
  • 3) eliminated the "need" for test wells and
  • 4) busted the myth of "mile separation" between wells

To learn more about this program, see the Groundwater Monitoring tab under the Research tab above. Contact OAI to see how this simple management program can be put into action for your system.

Hello 2017

OAI welcomes 2017 and looks forward to our 18th year of providing service to our 73 clients and welcomes others in need of professional hydrogeologic services to our website in the hope you will give OAI a call before you begin planning your next well.

December 20, 2016 Success!

On December 1st OAI submitted a request to the state regulatory agency for a review of a decades old closure report at a client's property, see December 1 below.  The closure, completed in 1991, was included in the Phase I report that recommended an $11,000+ Phase II assessment.  Nineteen days after OAI's submission of the closure report that was part of the ESA, the agency issued a "No Further Action" letter for the site.  It's only money...your money, spend it wisely.

December 10, 2016 Looking Good

The first year of monitoring is complete at this older well location and, despite a severe two month drought, the aquifer showed no significant impact due to lack of precipitation.  More importantly, the data suggests the aquifer is in balance and is likely favorable for the completion of another well in the aquifer.  An additional year of monitoring is underway to confirm seasonal effects and ensure stability in the aquifer is ongoing.

December 1, 2016 Environmental Problem

OAI was contacted to assist a client with a decades old environmental issue.   While OAI does not pursue "contamination related work", we do from time to time accept projects that are troublesome to the potential client if we feel we can help.  In this case, we did elect to help and outlined a process to follow to resolve the issue.  Stay tuned.

OAI's Temporary Field Office as MW-5 is Installed

October 4, 2016 Oklahoma Outreach

Continue OAI's efforts to bring hydrogeologic services back to the central Oklahoma area where I lived from 1981 to 1990. The area is plagued by recurring periods of drought the ultimately lead to water restrictions. If you are in the water sales business, restrictions are not something you want. Couple that with unsuccessful previous geologic efforts or low volume wells and it's time to look outside the box for solutions. That outside the box look should be eastward to OAI in Alabama. We are well experienced with the area's hydrogeology through our time in the area coupled with specific research that has identified promising opportunities to develop high producing wells with a sustainable source; wells resistant to periodic drought conditions that hamper lake based water supplies. To paraphrase our motto "it's time to put our Oklahoma State Hydrogeologic training to work in Oklahoma".

September 27, 2016 Groundwater Monitoring System

OAI developed a groundwater monitoring program for a waste water spray disposal field for domestic waste water, photo on left. The site is located in a rural area and is designed to manage and dispose of up to 120,000 gallons of treated waste water per day. The groundwater monitoring system consists of five strategically placed monitoring wells, see picture on left, that will allow monitoring of the groundwater in the upper aquifer for constituents required by the permit.

September 6, 2016 OAI's September E-mail: The Educated Guess


Football is here and for a few hours each weekend it offers an opportunity to escape the concerns of politics, work and how to handle the future of your water system. That's good news.

A while back while scanning newspapers, I came across the following quote in a newspaper; you know that thing that used to get ink all over your fingers each morning. Note: Names have been changed but the underlying facts are there.

“It’s an educated guess as to how long it lasts at that level,” he said. “Pumping is what dictates how much the water drops…the question is how low you can pump before you have to shut the wells off.” General manager of System X.

That quote is with respect to dropping water levels in the system's public supply wells and, with all due respect, if this guy is relying on an educated guess with such a critical factor for his source of water, best of luck to him and his system. The better answer is to obtain data to allow an evaluation of the situation and then formulate the appropriate response. That data can easily be obtained if one knows what needs to be obtained. (Hint: It's not just water levels.)

Unfortunately for this particular system, it has bee five plus years since the quote was made. Had the proper data been gathered over that five year period, the system would know what, if anything they needed to do and, as a side benefit, saved in excess of $60,000+ dollars on a fix that did them no good at all. But hey, it's just money...

If you are facing concerns with your water supply or feel you need a new well, now is the time to act. Proactive measures OAI offered "System X" could lead to significant savings to your development budget. Times are indeed tough and money is tight. We are available to meet with you or your Board to answer any questions you may have on our services. So make that call to OAI today. We look forward to hearing from you and are eager to address your needs.

Football anyone?

God Bless...

Another well completion in which OAI completed test bore logging (required in Alabama), pumping test evaluation and source water assessment services. Well #12, see below, tested out at 750 gallons per minute during the capacity test required for permitting purposes. The well’s design capacity is 500 gallons per minute. Well #12, photo on right, will operate at its design capacity on an “as needed” basis.

My oldest brother John died today (Obituary). Known as "OJ" to family, "unka John" to nephews and nieces, the "Dr. of Golf" on courses near and far and simply as Dr. O'Donnell to his many patients and their babies, John was a treasure to all he came in contact with. As the oldest, he was the one we all looked up to and he always was somewhere in the stories we’ve told for years; stories that made us smile. He knew how to lay a nickname on you and make it stick, he always was good to the kids and no gathering of Da Family was complete without him being present. From teaching checkers to nephews to doting on nieces, to tracking down that red solo cup (before red solo cups had their own song), or easing Judy’s car up to 56 mph to get down to a graduation (8th grade, high school or college-it made no difference), baptism or a Troy Home Coming game quicker, John made you feel special by showing up. May his soul rest in peace.

Just got word out of Kentucky that effective May 18, 2016 that I have been issued a new License Number. I remain available for hydrogeologic consulting on groundwater projects in Kentucky with my current license good through December 30, 2017 before needing to be renewed.

June 21, 2016

In June 2000, OAI began a project that resulted in the successful completion of a 500 gpm irrigation well "on island" in south Baldwin County. This area was reported to be subject to "saltwater encroachment" according to the "experts". Well, based on OAI's sound research, our client pressed forward against heavy opposition. Sixteen years later and no telling how many millions of gallons produced, the well is running just fine. What about the "saltwater encroachment" you ask? Nodda, nothing, no where. The chart below shows chloride concentration data of the produced water over the years. If you need water and the "experts" are giving you the thumbs down, call OAI. This client did and they have had a dependable irrigation supply for sixteen years and will have it for many more years to come.

Nell and I became the nana and papa to Irene Elizabeth O'Donnell, daughter of our son Sam and his wife Maggie. Irene, mom and dad are doing well. She's a beautiful little girl who we got to visit, hold and begin to spoil! Life is good and thank God for that.

May 25, 2016

Congratulations to Griner Drilling Service Company, Inc. and North Baldwin Utilities on the recent completion of Well #12 just north of Stapleton, Alabama. As part of the project team for this well, OAI provided wellsite geologic services including completion of the required geologic log of the pilot bore, aquifer testing coordination and analysis and completion of the required sourcewater assessment report for permitting the new well. The well’s design capacity is 500 gallons per minute. This is OAI's 31st project for Griner and OAI's seventh public supply well project for NBU.

May 20, 2016

Completed a cursory hydrogeologic review for a south central Alabama water system to identify potential aquifers in their service area with the best potential for development. In addition, the report identified one means of evaluating the primary targeted aquifer for a fraction of the cost of a test well program. The report is set to help guide the new well exploration program for the system.

OAI completed select distribution sampling for a local client. I wish my grand kids were here for this work at the fire hydrant!

OAI Completed Select Distribution Sampling for a Local Client

March 17, 2016

I know what you are thinking so Happy St. Patrick's Day. It was indeed a wonderful day I spent the morning working on an aquifer test to rule in or out the possibility of developing a second well at a client's existing wellsite, see below. While the test is ongoing, the initial data is favorable. The test involved pumping the existing production well at its design rate of 752 gpm and recording water level in it and an observation well 50 feet away. Once the test is finished, the data will be analyzed and it together with historic data will be used to determine if a second well can be developed on-site.

As many of you have come to know, OAI's hydrogeologic approach begins with research. This includes the accumulation of all existing available hydrogeologic data, the evaluation of that data and the formulation of a concept (prospect) that can then be pursued in a planned manner. Much like an oil prospect, a carefully developed groundwater prospect enhances the chances for success and lessens the chance of failure. OAI's research has led to the development of fresh water wells without "test wells", located "new" aquifers and led to a more efficient method of exploration and development of groundwater resources.

In the past, our research located three out of service wells, two for one system and one for another, that the current system employees didn't even know about. The two wells still had the pumping equipment and infrastructure present.

Numerous Abandoned Wells

In a current project, OAI's research lead to the discovery and location of numerous abandoned wells including the well pair seen below thought to be abandoned in 1956. While only the foundation remains, evidence of the two wells can be seen in the two holes in the foundation where the well's casings extended downward with the pump motors bolted to the top of the foundation. Additional research on this project found that this well pair consisted of one deep well and one shallow well with each capable of producing 600 gpm.

Research is key to OAI's groundwater development efforts. How about yours? If you have plans for a new well, contact OAI today. We are ready to put geology to work for you!

The finished product seen in the photo below will allow this OAI industrial client to reduce their purchased water cost with production from this new 300 gpm well. This well, the fifth well developed by OAI in the Theodore Industrial Canal area, tested out at 428 gpm. It will run as needed for makeup cooling water reducing the amount of water purchased for this use.

January 26, 2016

OAI welcomes our 43rd public water system, Perdido Bay Water, Sewer and Fire Protection District. OAI will be working with Perdido Bay WSFPD and their engineer Paul Darnell of DMD Engineers, Inc. to evaluate feasible and efficient means to increase their current production capacity through the development of a wellfield and to evaluate potential well locations for future planning purposes. OAI thanks Mr. Mark Bohlin, Manager and the entire Board for their vote of confidence in awarding OAI a contract.

January 20, 2016

Work on an industrial water supply project continues with the completion of a new 300 gpm well, the fifth industrial supply well under the direction of OAI in the Theodore Industrial Canal complex since our initial hydrogeologic research on the area in 2003. Total available production from these five wells is 2,800 gpm (4.0+ mgd).

January 11, 2016

OAI completed a modified pumping test on an industrial supply well with en trained gas in the aquifer's water. Due to the gas, specialized equipment was needed to produce the water and to monitor the production rate. Griner Drilling Service Company, Inc.'s custom designed wellhead configuration, see below foreground, was installed, a catch tank, background, configured and the test went off without a hitch.

OAI's Dan O'Donnell passed the TBPG Ethics test and received 1 PDH credit for watching the video and passing the test with a 90% score.

October 21, 2015

Just finishing up a sourcewater report for the White House Water System with a Monday delivery scheduled. This new well is the system's first public supply well. Congratulations to Mr. Ruffin Crook, Chairman, the Board and staff of this water system on their new well.

May 9 to September 29, 2015

Where or where does time go? This past summer has been very busy at OAI, so busy we have gotten way behind on our newsletters and this page. So to update:

  • OAI completed one new public supply well project working through Griner Drilling Service Inc.'s contract.
  • OAI completed the testing of a second public supply well for a rural water system with the surface completion currently underway.
  • OAI assisted a non-community water system, OAI's 42nd water system client, servicing an RV resort in their permit for public supply, our second effort for this type of NC water system.
  • OAI completed a hydrogeologic study that will lead to the development of an independent source of groundwater supply for a municipal water system currently purchasing their public supply placing them in full control of their system.
The Night Shift on a Deep Southern Louisiana Exploration Effort
  • OAI completed a deep well project, see below, that located a brackish water source to be used for industrial supply purposes in southern Louisiana (Dan is a PG in La.).
  • OAI provided an evaluation of and consultation on a pumping test data for a Mississippi public supply exploration effort.
  • OAI modeled a planned industrial supply well to determine if a permit was needed (it wasn't) and is in the process of developing that new well.
  • OAI complete three system wide Sourcewater Assessment/Contaminant Inventory updates required for re-permitting purposes.

May 9, 2015

OAI's president, Nell O'Donnell, obtained her BS in Nursing from the University of Mobile today. Congratulations to Nell on her earning this degree.

April 29, 2015 Welcome to Louisiana!

OAI received a contract to explore a deep brackish aquifer to determine it's potential to be developed as a source of supply for solution mining several gas storage caverns at a Louisiana salt dome. With this job, OAI now has established its presence in Alabama, Louisiana, Mississippi and Florida.

April 16, 2015

Received a contract to complete a hydrogeologic study for a municipal water system that should lead to the development of an independent groundwater source of supply. Control your source and you control your system's future.

April 3, 2015

OAI updated its Review webpage located under the Research page to include Case #5. If your exploration program relies solely on test well data for production well development, you may want to read over this Case Study.

St. Patty's Day Selfie

March 25, 2015

OAI delivered a hydro study that ruled out drilling in one area of the system's service area due to geologic factors (faulting and aquifer thinning). The study did identify a drilling location that targets a 71 foot thick section of a regional aquifer tapped by many public supply wells and several drilling sites that target a shallow aquifer with excellent production potential and equally excellent water quality. Plans are under way to implement the drilling program recommended in the hydro study. Stay tuned.

March 17, 2015

Well 'd like to say hello and God bless to all those of you out there that bleed red, white, blue and, on occasion, green! Happy St. Patrick's Day!

The happy birthday well this month is the 3rd industrial supply well OAI planned, modeled and permitted for one of our industrial clients. Not bad for an area where "groundwater was not available"!

March Industrial Supply (3rd Well) Celebrating a Birthday

February 20, 2015

OAI is pleased to welcome the CWM Water System as the 41st public water supply client to our fold. OAI will be working with Mr. Walter Scott, PE of Millennium Technologies, Inc. to determine the feasibility of developing a groundwater system for this rural utility. Initially, OAI will complete a hydrogeologic study that provides information on area aquifers, recommends drilling depths for targeted aquifers and identifies promising drilling locations for exploratory bores.

February 2, 2015

OAI has two public supply wells celebrating birthdays in February. One located in Mobile County and one in Baldwin County. Both are completed in a hydraulically correct manner. As seen below, not every well is an 1,500 gpm well. Sometimes in a quest for higher production from a single well, well design mistakes are made. OAI works to prevent design mistakes by recommending well completions that maximize what the aquifer will provide based on the hydraulics of the aquifer system. Get it? Got it? Good!

Came across this article on understanding LNAPLs and wanted to pass it along. Illustrated Handbook of LNAPL Transport and Fate in the Subsurface. The LNAPL illustrated handbook provides a blend of technical detail and real world conceptualization of the LNAPL problem and appropriate methods to investigate and manage it. The handbook also facilitates access to a wealth of detailed research, guidance and case study literature within the various topics covered. It will be useful to the practitioner and research communities, and also provide a valuable educational resource to others having a less direct interest or specialized knowledge.

Two of OIA's public supply wells are celebrating birthdays this month. Well C was the first well OAI was involved with for this system and their engineer. The well was completed at a location by-passed two years earlier due to misconceptions involving a "shallow aquifer". The aquifer was identified by OAI in our review of the system's exploration effort to date. The shallow aquifer was found suitable for public supply purposes and permitted as a shallow aquifer public supply well. MMHS-2, pictured below, was completed as the second well at a location originally developed in 2000. The well is completed in a deeper aquifer at the site and boosted site production to 1,200 gpm (See June 10,2008 below for more information).

Hello 2015!

Happy New Year

I was watching an old episode of the TV show Goldbergs where pops was helping out at his old furniture store. His big idea was to have a "Going out of Business Sale". Not that they were going out of business but to sucker people into the store so they could sell them furniture. That got me thinking about the hydrogeologic consulting business. While I haven't seen any going out of business sales, it seems a variety of means are used out there to lure customers (that's you) to various hydrogeologic firms. Be careful when this happens.

OAI's "lure" is our reputation as presented by our clients to their peers in the water production business. In fact, word of mouth is how we have attracted the bulk of our client base over the years. At present, we have 39 public water supply clients, the majority of which are repeat clients. Many of those who aren't repeat clients are so because they haven't had a need as yet for additional services such as developing a new well. We are confident that when they do have this need, they will fall into the repeat category.

To those who have entrusted us with your business over the past 15+ years, Nell and I are grateful. For those of you who are considering expanding your groundwater resources in 2015 and have not used OAI, we welcome you to check us out before settling for what may be a sales gimmick no more clever than the old "Going out of Business Sale".

In any event, God bless you all and have a great New Year.

November News sent out via e-mail. For your copy, click here.

November 1, 2014

November well birthdays include wells with the combined capacity to produce 3,900 gpm (5.6+ mgd). Ranging in age from 7 years to 14 years these wells are key components of these systems' groundwater resources.

October 21, 2014

Received notice from ADEM today that the industrial supply well OAI researched, planned, tested and permitted was issued Time Extension No. 3 to operate at its designed rate of 800 gpm. This well was the first of four wells OAI developed in the Theodore Industrial Canal area. The four wells are permitted for a combined production rate of 3.6 million gallons per day. That's a lot of water that does not have to be purchased!

News sent out via e-mail. Here it is for you.

Hello all,

It seems summer is underway with a very short break between a cool spring and the heat of summer. For the past two weeks the Mobile area weather has acted like there was “something” in the Gulf but no official storms yet. Let’s hope it stays that way.

OAI well project birthdays this month include:

  • Dauphin Island Water and Sewer Authority’s Well #6, permitted at 1,200 gpm, turns nine
  • Kushla Water District Well #4, permitted at 1,000 gpm, turns eight
  • Bay Gas #1, produces at 1,200 gpm, turns 4
  • Bay Gas #2, produces at 1,200 gpm, turns 4

We had a good time at the ADEM Groundwater Conference and did have a couple of key questions concerning what is a potentiometric surface and what is not a potentiometric surface. To be sure, failure to understand this term and how it is used will lead to confusion and erroneous groundwater maps. Erroneous groundwater maps should not be used for decision-making purposes. The figure below shows the electric logs of two public supply wells with their screened intervals represented by the hashed boxes in the depth column. The well on the left is screened in and produces from four different sand aquifers, color-coded blue, orange, yellow and red. The well on the right produces solely from the aquifer colored yellow. By definition, only the water level from the well on the right represents a potentiometric surface and, in this case, the potentiometric surface only for the yellow aquifer. Water level from the well on the left does not represent a potentiometric surface for any of the aquifers tapped by the well and, if used to develop a potentiometric surface map will provide erroneous information.

April 21, 2014

OAI introduces new service! Beginning today, OAI makes available to our clients Rate Surveys to help them formulate an effective rate for them and their customers. Who needs this service? Well, if you have not looked at your rates in the past few years, if your revenues are not covering your expenses (and that includes reserve accounts) and you have trouble covering emergency and preventive maintenance cost, you could benefit from a Rate Study. This process doesn't have to be painful or expensive as it uses information you should have readily available. Using the sound, proven methodology while working with you, OAI will assess your rates and make recommendations that will ensure they are equitable for all your customers, large and small.

April 10, 2014 OAI Selected to Present

We received word today that our presentation entitled "Aquifers" has been accepted for inclusion at the 14th Annual ADEM Groundwater Conference to be held in Montgomery on June 10th. The presentation covers aquifer terminology and attempts to present technical terminology in a manner that will be helpful to water system personnel, Board members and engineers (Yes even engineers!). Once properly understood and put into practice, many systems can use this information to save tens of thousands of dollars on developing/expanding their groundwater sources as many of OAI's clients have already done. Save the date. We hope to see you there!

April 9, 2014 Belated Congrats!

A much belated congratulations to Dan McCrory, Superintendent, and the City of Fairhope for their winning the ARWA's Best Tasting Water Award two years running! Fairhope is the third OAI client to win this award, Mobile County Water (1st Place) and East Central Baldwin County Water (2nd Place) in 2005, see below for their stories.

ARWA Best Tasting Water Award

April 8, 2014 Sticker Shock?

At some point down the road, your system will need to increase its groundwater supply to meet demand. Fortunately, you can take steps now to reduce exploration and development costs tomorrow. We know. OAI has done just that with several of our 39 water system clients in Alabama, Mississippi and Florida. So, as time presses on toward that point you will need your next well, consider one or more of the following actions now to greatly enhance your opportunity for significant savings "down the road".

  • Completing a hydrogeologic assessment of your existing groundwater resources
  • Implementing a groundwater level monitoring program
  • Aquifer testing to located "missed production"

O’Donnell & Associates, Inc. measures success for our clients by the volume of water produced not by the size of the project’s budget. Our projects have resulted in savings from $10,000 too as much as $1,000,000 dollars without loosing any production of groundwater resources. How does that compare to the cost of your last well development project?

Call OAI today for a no cost meeting to discuss your groundwater program. You potentially have tremendous amount to lose by not making the call.

April 5, 2014 Good bye Mary Nell

Today we lost Mary Nell, a beloved member of the "Mulherin Gang" who visited Woodlawn Swim Club each Wednesday evening all summer long. God Bless you and may you Rest in Peace. Mary Nell is seen in the August 8, 2012 newsletter brief below. She's sitting in the chair on the right end of the second row wearing a white t-shirt.

OAI issues our Asset Management educational email. This month's email concerns asset management and how it can (and should) work for your benefit. Asset management in this sense is defined as "a process for maintaining a desired level of customer service at the best appropriate cost."

Check Up Program for Small Systems (CUPSS) is an easy to learn program developed by the EPA in response to a clear need from communities to consolidate and package asset management materials in an easy-to-use, clear and update-to-date fashion. EPA's Office of Groundwater and Drinking Water (OGWDW) developed CUPSS with the help of a workgroup that included representatives from state agencies, technical assistance organizations, EPA Regional offices, and small waste water and drinking water utilities. With this collaborative approach, EPA was able to develop a comprehensive application that provides all the tools required to implement an asset management program and develop effective asset management plans.

OAI, an EPA Certified trainer for CUPSS, is available to put our training to work for you and your water system. To get started, simply contact us and put CUPSS in the subject box. In just a few short lessons, you will be in control of this new program and well on the road to:

  • Making more informed decisions
  • Saving time by planning work schedules ahead
  • Backing up budget talks with solid facts you can then present to your Boards
  • Improving customer service
  • Preparing an asset management plan in seven steps

CUPSS is valuable tool all water systems (and waste water systems) should be using. Start now by sending that email!

February 28, 2014

OAI issues the March educational email "OAI’s Hydrogeologic Input Pays". If you missed this informative email on how OAI's area experience turned a poorly performing and most likely "dry hole" leading test well into a very successful new 1,300 gpm public supply well. This well project was not far from where another utility initiated a ten test well drilling program that came up dry! Perhaps they should have called OAI first.

February 4, 2014

OAI issued the February educational email. This month's email focuses on OAI's Research and Planning services with an example of published data indicating only one aquifer is present and our research showing that there are in fact five aquifers present between ground level and a depth of 500 feet. This research led to the development of several public supply wells including several wellfields, the development of industrial supply wells that targeted aquifers not used by public water systems and no dry holes. If you did not get your copy, contact us and put OAI's Research and Planning in the subject box.

If your system is thinking about a new well, now is the time to contact OAI to learn more about the benefits our research offers your system.

If your system has drilled "dry holes" in the past year, learn how this information can be used by OAI to better your chances at a successful completion.

If you need more water but not enough to warrant a whole new well, our research of your existing system may be the answer that solves your needs.

Make that call today and get back to what you do best sooner...selling water.

OAI received certification that we had successfully completed the Environmental Protection Agency’s Check Up Program for Small Systems (CUPSS) Train the Trainer Series. CUPSS is an easy-to-use asset management tool for small* drinking water and wastewater utilities that provides a simple, comprehensive approach to help you develop:

  • A record of your assets
  • A schedule of required tasks
  • An understanding of your financial situation
  • A tailored asset management plan

CUPSS allows you to put your office PC to work in new ways that provide you with the information need to efficiently manage your system with the tips of your fingers. It can't get much easier than that.As an EPA certified Trainer, OAI is available to assist you with setting up the CUPSS software on your system’s computer and work with you as you set up your asset and financial base information. Once the basic information is input to the CUPSS program, daily, monthly and yearly work orders can be easily generated. Detailed asset maintenance schedules can be printed that target maintenance tasks using a risk matrix analysis approach. Financial inputs can be used for planning purposes by generating reports with raw numbers or easy to understand charts and tools.

If CUPSS sounds like a tool you would like to put to use for the benefit of your system, please contact O’Donnell & Associates, Inc. today and let OAI, an EPA certified trainer, get you started with this easy to learn management tool. Contact OAI.

*While the target market for CUPSS is small water systems with less than 1,000 connections, larger system benefit equally from use of the program.

Will the beating up of BP ever stop? We recently received a call from a law firm telling us we could get money from the BP settlement without having to show any damage! Enough already. Just to show BP wasn't the first to cause an oil release in the Gulf-certainly news to some-here's a figure from a 1910 article showing fields of floating oil on the waters in the Gulf of Mexico. The map was put together from reports of Captain's logs.

OAI initiated a sampling program to establish "background" methane concentration in a series of aquifers for a repeat client. The project included developing the area's hydrogeology, selecting representative wells for sampling targeted aquifers, selecting and implementing the appropriate sampling methodology. Several wells had to outfitted with pumps for the sampling event. Analysis of the samples provided the samples' methane concentration and its isotopic nature.

March 28, 2013

OAI successfully permitted a new well in the Alabama Coastal zone for a local plant, see below. This well further reduces this facility's dependence on "purchased" water. This is the third well in the wellfield planned and permitted by OAI for this facility. With the addition of this new well groundwater production is now 2.4+ mgd.

March 21, 2013

Fairhope Utilities, one of OAI's Baldwin County water system clients, was awarded best tasting water in the State at the Alabama Rural Water Association's 2013 Annual meeting. Fairhope is the third OAI client to receive taste test awards; the other two include Mobile County Water, Sewer and Fire Protection Authority and East Central Baldwin County Water. Way to go Fairhope and good luck at the National convention in Denver.

With about two year's complete data, the picture is well developed at the Gulf Coast Groundwater Research Center of the influence of precipitation on the surficial aquifer, see graph below. Base groundwater level runs between 6 and 7 feet of water over the logger, cooler groundwater is found in March and warmer groundwater is found in October. Of interest from the stand point of recharge are the temperature anomalies noted in the groundwater temperature during periods of heavy precipitation indicative of rapid recharge to the aquifer. Read moe about the importance of a groundwater monitoring program at OAI's Management page.

Two Years' Data on the Influence of Precipitation on the Surficial Aquifer

March 14, 2013

Aquifer testing began on one of OAI's central Mobile County public water systems to obtain information needed to evaluate the feasibility of developing a two well single aquifer wellfield. This test involved pumping the system's existing public supply well and recording drawdown and recovery in an adjacent test well. Preliminary data suggest the "interference" will not be excessive. OAI is obtaining additional data and will make a "go/no go" recommendation based on an evaluation of all relevant site data.

March 13, 2013

Aquifer testing began on a test well for one of OAI's north-central Baldwin County public water client's 8-inch test well to determine the production potential of a targeted aquifer. A decision to proceed with a public supply well will depend on both water quality results and aquifer hydraulics. The drilled site was selected from several promising location because it is extremely favorable to the system's hydraulics. Should the water quality and aquifer hydraulics prove acceptable, the system's first well will be completed at the site.

March 4, 2013

Work halted on one of OAI's Baldwin County public supply well projects due to disappointing aquifer test results. OAI received word that all further efforts to develop the aquifer tapped by the new well would cease after testing determined the aquifer's recharge rate was not favorable for long term usage. The aquifer in question was identified during exploration efforts and was found to have excellent quality water. Unfortunately, the aquifer's production potential was below expectations and would not support the desired 500 gpm rate needed to replace the Town's #2 Well. After meeting with the Town Council and later with the Mayor, the system's superintendent and the system's engineer, it was decided to regroup and, as finances are squared away, proceed with a new effort without the severe limitations that were placed on this exploration effort. Without restrictions, the chance of success will be greatly increased.

February 28, 2013

OAI completed geologic logging a 500-foot test bore in northern Baldwin County. The test bore was completed to evaluate potential sands (aquifers) underlying the site for consideration of being developed for public supply purposes. Geologic logs are required for all public supply well in Alabama. OAI has over 160 hours of wellsite geology training and 31 years of experience on bores ranging from less than 10 feet to greater than 29,000 feet. Geologic logs are a critical part of every exploration effort. If you are planning an exploratory bore for a new well, call OAI and ensure you cover all your bases for this required log. OAI's wellsite services have made the difference between a dry hole and a new public supply well.

Mardis Gras is here!

If you are planning to be in the Mobile area for Mardis Gras and your water system has an issue of concern about your groundwater resources, why not plan to visit with us about your situation? All it takes is a phone call to lock in a meeting time. Perhaps, working together, we can identify a solution to help you keep the water flowing. Contact us today and set up an appointment.

Putting the finishing touch on a new industrial supply well set to produce at the 750 to 800 gpm rate. This is the second well of this facility’s shallow wellfield. Once on-line the production from the shallow aquifer will be about 1,350 gpm (1.94 mgd). A third well developed by OAI at this site adds another 300 gpm for an overall daily industrial supply production potential of 2.37 mgd.

January 24, 2013

South Alabama Utilities' Calvert-Thyssenkrupp Deep Well is set to go on-line. The first of two wells planned for this location tested out at 1,865 gpm and will produce at the 1,200 gpm rate (1.72 mgd). The development of the second well with a target production rate of 1,000 gpm (1.44 mgd) will proceed as demand requires.

Good bye 2012, Hello 2013!

Nell and I would like to thank all those who have placed their trust in and business with OAI over the past year to make it a good year inspite of trying economic conditions. As we wound down 2012, I had a chance to visit a well OAI sited and permitted back in 2001. The well is our client's strongest well testing out a 1,900 gpm and permitted for 1,000 gpm. Since its completion in 2001, the well has produced in excess of 4.4 billion gallons of drinking water. Currently, the well's static water level is four feet higher than originally measured in 2001.

South Alabama Utilities' Calvert Wellfield

October 17, 2012

Stopped by South Alabama Utilities' Calvert wellfield today to see how things are progressing, see pic below. This is the third wellfield OAI has developed for SAU. The first well is in and work continues with the plant and the water tower. When complete, the wellfield will have a potential production capacity of 2.88 million gallons per day.

September 13, 2012

Received contract to proceed with development of the new public supply well for a central Baldwin County water system today. The work is a continuation of an exploration project begun earlier this year. The pilot bore for the new well shows the aquifer present as expected. Work on the production well is set to start October 1st.

September 11, 2012

Testing finished up on a new industrial supply effort for a Mobile area plant. Tests showed the water quality and production are acceptable. The planned production well will be the third OAI has completed at the plant further reducing the plant's purchased water expense.

September 1, 2012

OAI's work for Dauphin Island Water and Sewer Authority began in 2002. The project evolved into teaming with DIWSA and their engineering firm to research and identify a new source of drinking water for the island that is located some 3+ miles off shore Mobile County, Alabama. The target aquifer was identified, tested and ultimately a 1,200 gpm well was permitted. Due to Hurricane Katrina, the well was not brought on line for several years. It was recently brought on line along with its treatment plant and a new ground tank. Yes, OAI can help with developing new water supplies in the most difficult of circumstances. Need water? Give us a call and we will work to get the job done.

August 24, 2012

Fairhope's Well #10 turned five years old today. This 1,000 gpm public supply well is the fourth well OAI has done for Fairhope with no dry holes. It completes the third wellfield OAI has planned, tested and permitted for Fairhope.

August 22, 2012

Gulf Shores Golf Club's 500 gpm irrigation well turns 11 years old today. This well was researched, planned, tested and permitted by OAI under ADEM's Coastal Zone Regulation governing wells producing >50 gpm. Information gained from an aquifer mapping research project completed by OAI's Dan O'Donnell back in 1996 was instrumental in the development of this "on island" fresh water well.

August 18, 2012

OAI was awarded a contract for a central Mobile County water system to begin an evaluation on the potential to develop a second wellfield for the system. The system's first wellfield is three years old and operating as planned. The second site is home to the system's Well #1 and is underlain by four sand aquifers.

Pat Ryan, a friend of mine for the past 15 years, died today. I first met Pat in 1997 when I attended a Cursillo weekend. Pat sat at my table and for the next 15 years I would meet with him more or less each week to discuss how we were living our Catholic faith. In more recent years I would visit with him at the Little Sisters of the Poor home after he moved in in 2004. Pat was a master gardener who oversaw and managed the gardens at Bellingrath Gardens for over 30 years retiring in 1995. He was married to his wife JoAnn for 57 years with JoAnn preceeding him in death by one week. To all who knew you Pat, you will be greatly missed.

Tonight marked the end of "Mulherin Wednesday Night" at Woodland Swim Club. Each Wednesday I help with the Mulherin Home's adult mentally retarded as they visit and swim at Woodland. It is always a blast and a pleasure to be around such happy folks. Til next summer, be safe and I'll miss the "Mulherin Gang": Barbie, Marie, John, Brian Pat, Ricky, Lenny, Debbie "C", Mary Nell, Dana, Lorraine, Donald Wood, Debbie Huff, Tiffany and Ashley "the Driver".

July 11, 2012

Looks like this headline "Summerdale finds water source to replace contaminated well" sums up OAI's lastest effort with the Town of Summerdale and Krebs Engineering.

The Mulherin Gang in 2012

OAI updated the hydrogeologic study we completed for Summerdale in 2002 and worked with Krebs' Vince Lucido to locate a promising wellsite based on the updated work. OAI then geologically logged the test bore (required of public supply wells completed in Alabama) and recommended which aquifer to test. As noted in the article, the targeted aquifer looks good for development as a source of supply.

June 21, 2012

OAI receives a contract to provide equipment and consulting services on a stream flow monitoring project to evaluate an industrial well's discharge on an adjacent stream's flow. The initial project is set for 12 months with an optional 12 month extension. This is OAI's 17th contract with this client.

The Saraland area test well drilled May 29th is developed and currently pumping in the 290 to 300 gpm range. The water will soon be sampled for drinking water parameters. Stay tuned.

June 12, 2012

Groundwater sample results from an exploration test well for a new central Baldwin County public supply well sited by OAI came back today with all indications the water is suitable for use as a source of public supply. The production well is now in the planning phase and will most likely be "fast tracked" by the water system.

June 12, 2012

The company's GMC turns 6 years old today. I still have trouble backing it up.

June 11, 2012

Initiated a 24/6 hour aquifer test today on a new Washington County public supply well with the rates set at 500 and 750 gpm. The well is the result of a hydrogeologic study of Southeast Washington County completed by OAI in 2010. Test went smooth.

May 31, 2012

Henry County mineral assessment report issued.

May 29, 2012

OAI opened a field office in Saraland today as exploration drilling began for a new public supply well. The test site was one of three identified in a 2009 hydrogeologic study OAI completed of the Saraland area of Mobile County, Alabama. The targeted aquifer was poorly developed at this location. The secondary target aquifer at this location was present as mapped, was tapped by a six inch diameter test well and developed. The aquifer has an available head of 145 feet. Testing to follow.

May 19, 2012

OAI received a contract from a private Florida citizen to complete a mineral assessment for a property in Henry County, Alabama. The assessment will identify which minerals are likely to be present along with the potential to economically develop these minerals. This contract was a wonderful way to celebrate our 13th Birthday. It would have been even better if the client would have paid their bill. Now they'll never know what came up of interest after the left us un-paid!

May 19, 2012

OAI celebrated its 13th birthday today. We appreciate all our family, friends and clients for their prayers and trust in OAI for their hydrogeologic needs over the past 13 years and we look forward as we enter our 14th year providing quality hydrogeologic services to all. God bless all, Dan and Nell.

April 25, 2012 - Sound Advice

While compiling well information on a research project, I came across this, see below, scribbled on the margins of a well record. Seems to be good advice now as much as it was in 1987.

April 17, 2012

OAI releases video of simultaneous aquifer tests conducted on two industrial supply wells. The wells were set to produce at the rate of 1,001 gpm each (2.88+ mgd) and were tested to check on how they were holding up after one year in operation. The video shows the wells' discharge point then pans back toward the wellheads. The wells in question are spaced at 71 feet horizontally and produce from two hydraulically separate aquifers. To see the video, click here.

OAI is retained by Millennium Technologies, Inc. for hydrogeologic services associated with a new public water supply well. Millennium's Walter "Scotty" Scott, PE worked with OAI on a number of successful groundwater development projects across southwest Alabama while employed with other firms. For this first project with Millennium, OAI was asked to evaluated and rate pre-selected drilling locations for their potential to be developed as sources of public supply. Seven aquifers were identified underlying the sites with pros and cons identified for each aquifer and a recommendation was made for most favorable site and most promising aquifer to target.

David Head, Sr. RIP

Read today where David died. Back in 1994 when he was developing "Blue Heron" which later was renamed The Peninsula, David needed water and had been told by the experts that groundwater was not an option due to saltwater intrusion. Hearing his dilemma, I asked to meet with him and laid out a plan of research, testing and exploration for groundwater underlying his site. David believed in me and thus I got my first groundwater development project. The research paid off for The Peninsula with the development of a 350 gpm "on island" freshwater well, the first well permitted under the new Coastal Regulation governing groundwater extraction. The first well was followed two years later with a 500 gpm well in the same aquifer with these two wells becoming the first permitted (and only to this date) Coastal Zone wellfield. The rest, as they say, is history. Thanks David for your trust and believing in my ideas back in 1994.

Both wells continue to operate as planned and now OAI has become the leading provider of hydrogeologic services in the Gulf Coast area helping others with research, exploration, development and management of their groundwater resources. If the "experts" tell you no, give OAI a call and we'll see what we can do for you.

Hello 2012


December 2011

Happy Birthday MCW's Boykin Road Well (Well #8) Mobile County Water, Sewer and Fire Protection Authority's Boykin Road Wells is the first well sited by OAI for the water system. The hydrogeology was completed by OAI's Dan O'Donnell and was included in MCW's Wellhead Protection Plan Dan completed for the system. The well tested out at 1,900 gpm and was permitted for 1,000 gpm. Ten years on the Boykin Road Well continues to be the system's best well both production and water wise.

After an absence of nine years to a competitor, a client has returned to the OAI family. After a meeting to discuss issues that, if not handled correctly, could ultimately lead to shutting down the town well, OAI was tasked with a full review of the situation and charged with developing options for this system to consider for addressing their dire situation. With a tight schedule of one week, OAI came through three days early with three potential options. Work is progressing on two fronts with a final decision on which option to fully implement to be made in about two to three weeks. Although we would have preferred they never left, we are glad you are back in the OAI family and will, as always, work to solve their groundwater issues in the most cost-effective manner.

August 2011

OAI worked with a long time client's home office on three pumping tests to determine aquifer hydraulic characteristics. Each of these projects involved analyzing client provided pumping test data, determining aquifer properties of transmissivity, the coefficinet of storage and theoretical maximum production potential for the well.

August 4, 2011

Daniel and Krystin O'Donnell's first child, Daniel J. O'Donnell, III, was born today at 03:17 Mountain time at Fort Bliss in El Paso Texas. "Trip", see below, is our first grandchild and we are thrilled. Daniel called from Afghanistan to let us know Trip was set to arrive and Dick Coldwell, Krystin's dad called with the news of the birth. Both mom and baby are doing fine and we thank God for that. Thanks and God bless you both Daniel and Krystin. Nell and I look forward to holding your new baby.

Since forming in 1999, OAI has worked with water systems, engineering firms, industry and irrigators to develop wells with a combined production capacity of 50+ million gallons of water per day. This year alone we are working on four well projects that will increase the 50+ million gallon total by another 5.1+ million gallons per day.

July 4th

Enjoy the 4th with your families but say a prayer for our Troops.

The Grilling is Fine, Happy Fourth of July from OAI!

June 10, 2011 OAI Loggers help out on aquifer test.

OAI's rental loggers were "instrumental" in the acquisition of water level data on recent testing for a Daphne Alabama production well. The data loggers recorded pre-test, test and post-test data on the required 24/6 hour step rate aquifer test required as part of the permitting process. If you have an important aquifer or pumping test coming up, contact OAI to set up a very competitive logger rental package that provides you the data needed to make the right decision. We also provide analysis of the test data if needed.

June 9, 2011 New bore looks good.

OAI just finish geologically logging a 995 foot test bore in Washington County Alabama with all indications the test site is favorable for being developed with a new high volume public supply well. OAI's hydrogeologic review helped in identifying this test site. To date, OAI has geologically logged 10,797 feet of public supply and industrial supply wells in Washington County.

Just as important to geologic logging, geophysical logging is a critical tool that allows for a complete evaluation of the subsurface formations penetrated by the drill bit. Geophysical logs are run on the open borehole after drilling reaches total depth. In the photo below, the e-log of the test bore geologically logged by OAI shows that the aquifer present at a depth of 238 to 290 feet is clean (i.e. no clay layers) with resistivity curves indicating that it contains fresh water. The combination of geologic and geophysical logs ensures that the aquifer with the best potential for development can be targeted for testing. Exploratory bores completed without the benefit of a hydrogeologic review before drilling and the wellsites services of geologic and geophysical logging during and after drilling can be and usually are a waste of time, money and effort (aka a dry hole).

June 6th

OAI opens new field office, see below. OAI's new Washington County field office is located just off Highway 43 at the intersection of Toinette Road. The office was set up to provide support services to drilling operations associated with Washington County Water's exploration program. The field office will be staffed full time during drilling operations by Dan. On site activities include catching and describing lagged samples, recording the lithology and monitoring drilling operations. At total depth, OAI will monitor geophysical logging and make recomendations on which aquifers to target for development.

The drought cometh is your System prepared?

May 28, 2011 DROUGHT

Once again the southern 2/3rds of Alabama, coastal Mississippi and the Florida panhandle are in the midst of the third (or fourth??) drought in the last eleven years. As of today, the Mobile area is running about 15.96 inches behind normal with area lawns brown, crunchy and in need of dusting. Some area towns, see photo above, have begun asking consumers to conserve with others implementing even/odd watering restrictions. Both measures lead to a reduction in sales (i.e. revenue) for the systems. If your system is considering conservation measures or water restrictions due to the drought, please also consider making a call to OAI. We can't make it rain but we can assess your groundwater assets and identify measures that may allow you to maintain your sales. Economically, times are tough so why add decreased revenue to the mix. During the Drought of 2007, OAI identified a solution for one south Alabama system that allowed them the option of foregoing development of a new 1,400 foot deep ell in favor of a $50,000 fix to their existing infrastructure and a return to their pre-drought water use policy. So if this drought has you worried, call OAI today and let OAI work to keep you in the water sales business.

May 24, 2011 OAI Analysis Requested on Pumping Test Data.

OAI's input was requested and delivered on the analysis of data from pumping tests completed on two Mississippi test wells. The data was reviewed and an opinion delivered on the feasibility of developing high volume public supply wells. One got a thumbs up and the other's data was not favorable for developing a well at the production rate sought.

April 26, 2011

Once upon a time a small municipal water system began planning that would ultimately change them from a "purchased" water system to a system fully in control of their water resource. Their quest began with a call to OAI, the leading groundwater resources development firm in the Central Gulf Coast area. OAI met with them and listened to their needs. OAI then provided them with a tour of several public groundwater systems in the area which OAI worked to develop. The typical comments "I had no idea how efficient a groundwater system is" or "That's the full extent of the treatment/production infrastructure?" rang true once again. OAI then presented them with a carefully thought out research and exploration program to fully develop their own groundwater supplied water system. The project progressed as planned and a groundwater supply necessary to meet their system's demand was brought on line. Today, April 26th, the ribbon cutting was completed and all lived happily ever after.

The above fairy tale need not remain simply a fairy tale. If you are a Mayor, Board Chairman or person with the responsibility of your system's water resources and would like to say good bye to purchasing your water needs, do yourself a favor and contact OAI. Perhaps we can provide you with an option, your own source, that you have wanted but were told was not practical. The fact of the matter is that it may be more practical than you ever imagined.

Develop your own water source and you control the revenue stream. It’s that simple. By developing your source of supply, you control the water and the revenue that selling the water brings. Poorly run, a city/system owned utility that controls its own source generates revenue. Run properly, it generates a lot of revenue. It all starts with a vision, a step of faith and a phone call, so contact us today. We are waiting to hear from you.

April 15, 2011 And they said it couldn’t be done!

With the possibility of the end of an 11-year tradition hanging in the balance due to my brother Tom "Mr. French Fry" O'Donnell moving away, Dan* accepted the formidable task of taking on the French Fry cook position, see small photo below, that Tom mastered over many years. Lo and behold, the 12th Annual St. Pius X Church Lenten Fish Fries run by K of C Council #13085 went off like clock work.

*I had eleven years of French Fry apprenticeship under Mr. Tom's careful direction, so don't try this at home without similar experience. You have been warned.

March 19, 2011 Year One Completed.

Information provided by the logger in OAI's MW-2 shows that groundwater reaches maximum temperature in October and reaches its lowest temperature in March. The high temp, 22.68 degrees Celsius (C) (72.82 F), was recorded at 4PM on October 11, 2011. The low temp, 16.50 C(61.70 F), was recorded at 2PM on March 12, 2010. The water level plot resembles that recorded earlier between 2007 and 2009 with fluctuations due to significant precipitation events. The plot of the last year's data is seen below.

Question: Does OAI "do" environmental work?

That's a very good question and we'd like to take this opportunity to address it. While we do not market the "environmental" realm of the hydrogeologic field, that being UST, AST, hazardous/non-hazardous chemical releases and such, we are trained and have extensive experience in these areas. We do provide services in these areas on projects from time to time for our existing clients and new clients that have found themselves with ongoing and troublesome projects that seem to have no end in sight. Each of OAI's environmental projects start with a thorough review of work completed to date to identify potential actions taken that can lead to bigger problems than the initial release itself. For example: Your site had a release of 20 gallons of unleaded gasoline to a shallow aquifer 30 feet thick with a water table at 10 feet. A 25 foot thick clay underlies the shallow aquifer and then another 40 foot thick aquifer underlies the clay. More often than not, an investigation of this release would before long include drilling through the underlying clay, setting a deep monitoring well and "finding" that the lower aquifer is contaminated. OAI simply asks: "Why was this action taken and What is the cause of the contaminated lower aquifer?" These are two critical and costly questions that can entangle you with years of expense and heartache over something that was and should have remained a minor problem limited only to the upper aquifer. If this is the type of "environmental problem" you have, it's the kind of environmental problem we "do". Give us a call and let's sit down, review your particular situation and work together to resolve your problem not make it worse. If you are looking at an environmental problem and haven't contracted out the work, give OAI a call and spare yourself the headache mistakes can make.

February 14, 2011

It pays to know. A local water Board was shown the benefit of their groundwater level monitoring program with a presentation on the "before and after" of their program. The program, initiated in 2005, paid off for them in 2009 when they were in need of a new well to meet demand. The data showed their aquifer was in balance and capable of supplying another well. Testing confirmed there were no hidden problems and a second well was added. The presentation tonight confirmed that the aquifer has not been over stressed by the addition of the new well. Savings to the system included: no land purchase, minimal piping costs as the wells are at the water tower, no test well costs (we went straight to the production well) and best of all no dry hole costs.

October 7, 2010 - Groundwater Management Question

Groundwater management should be a vital part of any groundwater system. Yesterday, while visiting with a system manager the following question came up "Where should the observation well be placed for a monitoring program"? This is a good question and, as in most things, the answer is "It depends".

Since 1995, public supply wells in Alabama require an observation well as part of the permitting process. As this observation well is already in place (and paid for) and it is generally within the fenced, secured area of the new well, OAI uses this well as the monitoring point. This reduces the expense of another well and, even more importantly, reduces an un-necessary vulnerability point and possibly even another artificial penetration of protective clays overlying the producing aquifer. Where as the completion of a new observation well for monitoring purposes increases costs, adds a potential high risk sourcewater threat and may lead to further penetrations of protective clays.

To the question: "What about interference from pumping?" we say that is what you are wanting to monitor so why not monitor at the point of critical impact? The interference seen in the vicinity of the well is what is critical to evaluating the health of the aquifer. By monitoring away from interference effects of the production well, critical water level data on what is actually going on at the well may be lost.

So, when setting up a monitoring program, if money, aquifer protection and further reduction in protection of overlying clays doesn't matter, go ahead and drill a new observation well away from the production well. However, OAI suggests using what is already available at the wellsite which saves money, reduces security issues, eliminates additional penetrations of protective clay layers and provides the "at well" data you need to manage your water resources. To set-up as cost effective, secure monitoring program, contact OAI. The money you save is yours to keep.

September 1, 2010 Need a new well?

Times are tough and money is tight. So if you are planning to complete a new well for your water system, we have a new article for you entitled "Who ya gonna call?" The article gives two casebook examples of how OAI worked with two clients to solve their water needs. Perhaps your system could benefit from a hydrogeologic review to determine whether or not you actually need a new well or simply a modification to your existing infrastructure.

If you are a utility manager, an engineer or a plant manager and need help with your water supply, where ever you may be, give OAI a call and together we'll see whether OAI can make a difference for your project. We travel, so don't let the distance between your location and our location stand in the way of solving your water needs. Make that call today.

July 4, 2010 - Happy 4th of July

We had a great 4th with friends and some of Miss Nell's homecooked ribs, photo below. I can't wait 'til the next aquifer test as I picked up a new idea for the 6-hour food break. The pump is on at 06:00 and supper's served at 12:00. Ready, set, go.

May 11, 2010 - Industrial Wellfield Completed

What began with a consultation visit in December 2008 was finalized with the delivery of the Wellfield Report for and surface completion of a multi-well, multi-aquifer industrial supply wellfield, photo below. From researching and identifying potential aquifers and locating favorable wellsites through testing the aquifers for hydraulic performance and water quality to completion of the two production wells, OAI worked diligently with the client and the drilling contractor to bring about a successful conclusion to this project. The wellfield's two wells are spaced at 71 feet horizontally and produce from aquifers separated vertically by 150 feet of clay. The wellfield has the capability of delivering 4.32 million gallons per day but will produce at the rate of 2.16 million gallons per day. The aquifers underlying the site have an ultimate potential of producing as much as 12.96 million gallons per day.

May 6, 2010 - Hydrogeologic Study Completed

Delivered a hydrogeologic study today to a public water system that identified six aquifers, five of which have the potential to be developed as sources of public supply. Among the five aquifers, two are currently used as a source of public supply and three have been used for drinking water or industrial supply purposes. The study identified favorable drilling locations, provided target drilling depth and located wells that can be sampled to provide preliminary information of the water quality for the aquifers under consideration. The next phase of this project involves implementing the recommendations to evaluate the aquifers' potential to be developed as a source of public supply.

April 26, 2010 - OAI re-locates to new office

October 18, 2009 - All systems go

Water samples obtained from test wells in Calvert indicate the site is a go for development of one and possibly two aquifers as demand increases in the future. Extended testing is planned for one of the aquifer that has water on the border line for post production testing before plant size is finalized.

October 1, 2009 - Welcome aboard Saraland!

On October 1st, the Board of Water and Sewer Commissioners of the City of Saraland retained the hydrogeologic services of OAI to assist them with the exploration and development of a new well or wells. The initial phase of the project is a hydrogeologic study of the Board's service area to identify promising wellsites. OAI thanks Mr. Mike Sullivan, Superintendent and the Board and Mr. Gordon Quesenberry, PE of McCrory and Williams for their confidence in selecting and recommending OAI for this project. Saraland is the 37th Gulf Coast public supply water system to select OAI for their exploration and development project.

September 29, 2009 - Calvert Exploration

OAI received a contract to assist South Alabama Utilities with an exploration test in the Calvert Community. The project will begin with geologic logging of an exploratory bore and progressed with testing and development of promising aquifers found through the boring effort.

September 18, 2009 - Deep Clarke Test Abandoned

The deep Clarke County exploration project found the target aquifer as expected but preliminary water samples obtained from the test well indicated that the water would required post-production treatment prior to being suitable for use as a source of public supply. As a result, development of the deep aquifer has been abandoned.

August 10, 2009 Exploration Test Begins

Drilling began today on a deep aquifer in Clarke County Alabama, see photo below. The test is the result of OAI's hydrogeologic study of the central Clarke County area that identified the Gravel Creek member of the Nanafalia Formation for possible use as a source of public supply. Drilling is expected to take eight days with the target aquifer expected at a depth of 1,730 feet.

August 6, 2009 - OAI in Print

The August 2009 issue of the Alabama Geological Society's newsletter contains an article written Dan O'Donnell about a field methods mini-camp he ran in May of 2008. The paper explains how a group of professional geologists doing the same task-a water level survey-came up with a wide variety of data. The article shows how attention to detail is often lacking on one of the most critical parts of a groundwater investigation. You can read the article beginning on page 7 of the newsletter by following this link. Have your employees* properly trained in conducting and interpreting water level surveys at OAI's Gulf Coast Groundwater Research Center. Please contact us to schedule a training class. A well trained employee is an asset to any firm.

*Training is also available for geology/environmental students looking for practical experience prior to entering the job market.

July 2009 - Testing proves out OAI's hydrogeologic study

July was a busy month at OAI as fieldwork continued on a proposed industrial supply wellfield, see below. The second of two test wells was installed and testing confirmed a second aquifer underlying the site is satisfactory for use as a source of industrial supply. Planning is ongoing for two production wells. The ultimate production for the two well wellfield should fall in the 1,500 to 3,000 gpm range (2.16 to 4.32 mgpd) with options to increase production with additional wells in the tested aquifers or by tapping an un-tested third aquifer that underlies the site.

July 15, 2009 - Groundwater level monitoring pays off

On July 15th, a client called to ask us to check our data logger at one of their critical wells. It seems their equipment signaled the well was about to break suction due to excessive drawdown and, as a result, this much needed well was taken out of service. OAI travel to the site and evaluated the data our logger recorded only to find out everything was normal with no excessive drawdown occurring in the aquifer at this well. This critical well was immediately placed back into service. Without having implemented OAI's groundwater level monitoring program at this well, this system could have spent thousands of dollars and had the well out of service only to find out nothing was wrong. Does your system have a groundwater level monitoring program? If not, contact OAI today. The money (and headaches) you save may be your own.

June 11, 2009 Running Casing

On June 11th, casing was set for a test well on a project associated with developing an industrial supply wellfield with an upside production rate potential of 1,500 to 3,000 gpm. The test well location was identified through a hydrogeologic study completed by OAI in January of 2009. The primary target aquifer proved out at 145 feet thick and is composed of a mix of sand, fine gravel and gravel. Two additional aquifers were found as expected and await testing. During the casing run, OAI provided "casing burgers" for all those on site, see photo below. Testing will begin soon to determine the aquifer's production potential and water quality.

June 3, 2009 - Primary Target Aquifer

The target aquifer of an industrial wellfield project was cut today with excellent aquifer material cut over a 145 foot interval. OAI completed a hydrogeologic study to identified the drilling location and wellsite services to catch, examine and record the material cut by the bit. The primary aquifer came in as expected and consisted of sand, fine gravel and gravel, see photo below.

April 28, 2009 - Advertising

O'Donnell & Associates, Inc. would like to use this opportunity to thank all our clients who have referred their friends to us for hydrogeologic services. Often times these references can lead to just a quick phone call to us about a well issue, an aquifer question or the like. Sometimes the reference can be a substantial lead that develops into a water supply exploration, development or management project. In short, word of mouth referrals have been and remain our main source of advertising. A hint of why our clients refer others to OAI for help in addressing their groundwater resources needs may be found in an e-mail sent to OAI from a regulator at the Alabama Department of Environmental Management candidly speaking of our sourcewater assessment reports. From day one, quality hydrogeologic services for our clients have been our priority.

April 7, 2009 - National Honor Society

Today brought recognition to our son Sam, left, with his induction into the National Honor Society at Murphy High School (Go Panthers!). Sam and his friends, Lam Pham and Dillan Brewer, are pictured below at the reception following the awards ceremony.

April 2, 2009 - Irrigation Success

OAI's best source of advertising is our satisfied clients and for that we are grateful. One such client referred the manager of a local blueberry farming operation to OAI for help in locating an irrigation well after previous efforts were disappointing. OAI accepted the task, did a review of the area's hydrogeology and recommended a drilling depth. The farmer took the recommendation and contracted a local drilling firm to drill to a depth of 250 feet. The target aquifer came in as expected and the well was completed with 30 feet of screen. The well has a good production rate and, once the rain stops falling, the blueberries will be put out...

March 28, 2009

On March 28th, we recorded 7.1 inches of rain over the previous 24-hour period. The groundwater elevation at OAI's MW-2 rose to 16.96 feet in response to the rain event, the highest recorded over the previous two years, see the research link for the graph.

We received word today that Doyle McCullar, Nell's father, has died. Doyle was a good father, excellent carpenter and friend of many stray dogs. May he rest in peace.

February 2, 2009-Grove Hill Water Works

OAI welcomes Grove Hill Water Works into our family of water system clients that now numbers 36 systems across southern Alabama, southeast Mississippi and northwest Florida. OAI will complete a hydrogeologic study with the intent of locating a favorable drilling location for their next well.

January 31, 2009

OAI's groundwater level monitoring program has recorded 13,900+ measurements at MW-2 dating back to April 2007, see below. MW-2 is a 13.5 foot deep monitoring well located in a surficial aquifer adjacent to Eslava Creek in Mobile, Alabama. Beginning January 21, 2008, OAI joined the Community Collaborative Rain, Hail and Snow Network, and has tracked and posted precipitation data collected at the location of MW-2 on line. Together, the water level data and the precipitation data make for an interesting graph, see below. Notice the correlation between precipitation events and the groundwater elevation recorded at the well. Read more about this effort on OAI's Research page.

Groundwater Level Monitoring Graph, April 1, 2007 to January 31, 2009

Hello 2009!

To all our clients and friends, we wish you a blessed and prosperous new year! We would like to thank all our clients for making 2008 one of our best years with a wide variety of fun, challenging and successful projects. Along the way, we added to our client base: one major engineering firm, three industrial clients, three public water systems and a local nursery. The majority of these new clients are a result of direct referral from satisfied clients.

Accomplishments in 2008 include hydrogeologic services that resulted in the permitting of four municipal wells with a tested production capacity of 5.9 million gallons per day and a permitted capacity of 3.96 million gallons per day. OAI also planned, tested, developed and permitted two new wellfields, a multi-well, multi-aquifer wellfield and a single aquifer multi-well wellfield. We also complete three hydrogeologic studies to assist in the planning, drilling and development of future municipal wells (the OAI way to effectively develop groundwater resources). In another area, our groundwater modeling experience was used to support not having to permit two industrial supply wells under the Coastal Regulations which resulted in a saving of $15,000 to $18,000 for each of two of our industrial clients.

We look forward to 2009 in anticipation as we complete our tenth year in the business of exploration, development and management of groundwater resources for our municipal, industrial, and private sector clients. As the ideas formed on the pages of our studies become your new water supply wells, we have to pause and reflect that it just doesn't get much better than this. Thank you all for your business and support of our firm.

God bless you all and here's to a great 2009.

December 28, 2008-Bob Craft-RIP

On December 28, 2008, Mr. Gilbert Robert "Bob" Craft, Executive Director of South Alabama Utilities, passed away. Mr. Craft was a forward thinker who I first met in 2000 while conducting an aquifer test at SAU's Mary Montgomery #1 Well. I have had the privilege of working on many more of SAU's water well projects and always enjoyed Mr. Craft's visits to the job sites. Once while taking Troop 36 Boy Scouts to Mass during a weekend campout in Citronelle, I ran into Mr. Craft and his wife Pat and was complemented on what a fine group of boys our Troop had. He will be missed.

Groundwater monitoring efforts at six municipal water supply wells were terminated after 4.5 years of monitoring found no indications the aquifers being monitored were being over produced. The water level data recorded since May of 2004 provides the utilities that owned the wells valuable information on the overall health of their sources of supply and will provide a baseline for future comparison should they consider the possibility of tapping the aquifers with additional wells. Groundwater level monitoring continues at six other sites in aquifers tapped by 12 public water supply wells.

Welcome Bayou LaBatre! OAI received a contract to provide wellsite geologic services to Bayou LaBatre Utilities as they begin the process to develop a new water supply well for their system. Geologic logs provide valuable information that can make or break a decision to complete a well. Geologic logs are required for all new public supply wells in Alabama. OAI has 160 hours of formal training in mudlogging, 29 years of "mudlogging " experience and has logged over 37,000 feet of water wells in Alabama's the coastal plain. With the addition of Bayou LaBatre, OAI's public water system client base is now 35 systems. Thank you all.
