Locate a Well
When a new well is drilled, drillers submit a well report that includes the well depth, construction, and date it was drilled. If you are looking for a well record, there are two online resources available to help you locate it.
Wells Drilled from 2003 – Present
Water Data Interactive – Texas Water Development Board
Wells Drilled before 2003
Historic Well Log Viewer – Texas Commission on Environmental Quality
Test Well Water Samples
It’s important to understand and check the quality of water your well is producing. At minimum, it’s recommended to test wells annually for E. coli bacteria and nitrate-nitrogen. If your water suddenly has a change in taste or smell, test your water as soon as possible to help identify the cause of the change and how to resolve the issue.
While the District hosts well water check ups annually, well owners can get their water tested at anytime at the following local labs:
