Water Wells in Hardeman County Need a Map and a Test

Outside town, a well may be part of the water plan. Hardeman County groundwater is not one simple bucket. TWDB Report 161 points to the Blaine Formation and alluvial terrace deposits as major sources.

The same report says water quality varies. Alluvial water is very hard, and Blaine Formation water can be more mineralized. A stock well is not proof that the water is right for a kitchen sink.

TWDB's groundwater database can show nearby well records, water levels, and water-quality samples. Use those records as a starting point, then test the water on the tract itself.

For local rules, use the TCEQ GCD Viewer. In a July 2, 2026 check, that viewer showed Hardeman County intersecting Gateway Groundwater Conservation District. If a tract falls inside a district, ask about registration or permits before drilling.
