The Well Protection Program supports the Edwards Aquifer Authority’s (EAA’s) mission to effectively manage and protect the Edwards Aquifer by accounting for all wells (operational and non-operational) and ensuring that wells are properly constructed and maintained. Wells in poor condition pose a significant risk of contamination to the aquifer. Through the Well Protection Program, EAA staff documents and inspects registered wells, observes for unregistered wells and also searches for wells that have been abandoned. To report an abandoned well or if you have questions about any specific well in the EAA’s jurisdictional area, please call the EAA at (210) 222-2204 or (800) 292-1047.

Yes. State law requires all wells within the EAA's jurisdictional area that produce water from the Edwards Aquifer to be registered with the EAA. Registration requirements help protect our water supply by identifying all points of withdrawal from the aquifer and allowing us to identify potential contamination risks associated with abandoned, poorly constructed, or deteriorated wells. Also, if an aquifer contamination event occurs, having your well(s) registered enables us to effectively communicate important health and safety information to you in a timely manner so that you can guard against possible threats to your water supply.

An important aspect of the Well Protection Program is to ensure our records are up to date. For your benefit, we ask owners of previously registered wells to notify us of any ownership changes. These changes can be made at no cost by submitting a Well Ownership Update form. During an inspection, we will make a general assessment of the condition of the well including taking pictures and recording its precise location.

By assesing the physical location and depth of your well, EAA staff can usually determine if it is an Edwards Aquifer well. You may contact our office directly or go online to complete a well registration form. The information you provide will help us evaluate whether your well draws water from the Edwards Aquifer.

No, not with the EAA. Since EAA only manages the Edwards Aquifer, we are only responsible for wells that withdraw water from the Edwards Aquifer. However, while not required to be registered, wells drilled through the Edwards Aquifer into other aquifers may be required to be inspected if there is a water quality concern associated with an abandoned, deteriorated, or poorly constructed well that transects the Edwards Aquifer.

Yes. All Edwards Aquifer wells located within the EAA's jurisdictional area, regardless of purpose of use, must be registered and inspected—even household and/or livestock wells.

Please give us as much information as possible. You may leave blank any information you do not know and we will follow up with you to complete the information.

Simply include any relevant, descriptive information about the location such as physical landmarks that will help us locate and identify the well such as "windmill at the northwest corner of the intersection of FM 1217 and Hwy. 21.

Periodic inspections are recommended as a means of preventive maintenance. Also, confirming water use, general well specifications, and overall condition of the well are necessary to ensure compliance with applicable laws and can happen only with an inspection.

During an inspection, we will make a general assessment of the condition of the well including taking pictures and recording its precise location.

Most wells will be inspected approximately every 10 years unless something has occurred that may trigger the need for a more frequent inspection―such as development activities nearby or an aquifer contamination event.

Yes, the inspection is necessary as part of the well protection program. EAA staff will make every effort to schedule your well inspection at your convenience with minimal intrusion into your property.
