Where to get information about wells

January 01, 2021

The Lone Star State is home to more than a million water wells, according to the Texas Groundwater Protection Committee. If your clients have questions about a well on their property, a well on a property they’re interested in, or drinking water in general, share these state and federal reports and databases:

The Submitted Drillers Reports Database has more than 270,000 reports dating back to 2001. It is maintained by the Texas Water Development Board (TWDB) and Texas Department of Licensing and Regulation. The database is searchable by map, tracking number, county, use, and owner name. www.twdb.texas.gov/groundwater/data/drillersdb.asp

The TWDB Groundwater Data Viewer is an interactive map that can access roughly 139,000 water well reports and has information on some wells as far back as 1820. www3.twdb.texas.gov/apps/WaterDataInteractive/GroundWaterDataViewer

The Texas Commission on Environmental Quality (TCEQ) Water Well Report Viewer is also a map-based viewer that can search over 1 million well reports dating back to 1960. tceq.texas.gov/gis/waterwellview.html

The TCEQ Source Water Assessment & Protection Viewer includes well and surface water information for public water systems. The map interface will show search results. tceq.texas.gov/gis/swaview

The TCEQ Texas Drinking Water Watch allows searches of public water systems by water system name, activity status, principal county served, water system type, and primary source water type. https://dww2.tceq.texas.gov/DWW/

Other sources of information are the local groundwater conservation district (accessible from texasgroundwater.org) and The United States Geological Survey National Water Information System (waterdata.usgs.gov/nwis).
