Notes from the Groundwater Guy by Thomas E. Ballard, P.G., C.H.G. Southeast Hydrogeology, PLLC The Importance of Teamwork We have talked a lot here about diagnosing and solving well problems, but we do not do it in a vacuum. I want to give a shout out to all the chemical suppliers and drilling, well rehabilitation, and well repair professionals. We can diagnose a problem and design a solution, but without a good contractor to implement the plan properly, it is just so many words on paper. We work as a team to deliver a great solution to the clients who are trying to fix their well issues, whether it is a repair, rehabilitation job, or a new well - so we always ask the contractors how we can we work together most effectively. Well rehabilitation and maintenance work can be a great revenue enhancer for a drilling business, but it needs to be done right. Well rehabilitation is definitely not a one-size-fits-all type of approach, so it is important to conduct a proper assess- ment of each well and design a solution for the conditions present in that specific well. We have found that groundwater chemistry, microbial populations impacting wells, and even aquifer properties can vary significantly over relatively short dis- tances. There are distinct steps in the process to a successful well rehabilitation: 1. Well health check is a crucial first step to get a snapshot of the condition of the well; check the water chemistry and microbiological impacts to the well; and to start understanding the limiting parameters for designing the well reha- bilitation solution. 2. A video survey to assess the extent of the plugging, corrosion, or structural damage to the well and determine whether rehabilitation is even feasi- ble. 21 WorldWide Drilling Resource ® MAY 2020 Atlantis Vault • Self-Contained • Simple installation • Trouble-free operation For more information call: (270) 786-3010 or visit us online: www.geothermalsupply.com WTR Ballard cont’d on page 34.
