Well RegistrationState law requires all wells, regardless of their age, that withdraw water from the Edwards Aquifer to be registered with the EAA. Registration helps us protect our shared water supply by identifying all points of withdrawal from the Aquifer and allowing us to properly address potential contamination risks due to abandoned or poorly constructed wells.
Registration also protects the well owner in the unfortunate event that contamination does occur. Knowledge of a well’s location allows the EAA to effectively communicate important health and safety concerns to individuals who may not otherwise be aware of a possible danger.
To register your well, please submit a completed Well Registration Form along with a check or money order for $10 for each well registered to:
Edwards Aquifer Authority
Attention: Well Registration Program
900 E. Quincy
San Antonio, Texas 78215
If your well has already been registered by a previous property owner and well ownership has changed, please fill out a Owner Update Form so that we can make changes to our records at no cost to you.
To verify whether you have an Edwards Aquifer well, to report an abandoned well, or if you have any questions, please call the EAA Aquifer Protection Team at (210) 222-2204 or (800) 292-1047.
