Water Wells
Hardin County has no groundwater conservation district — wells are less regulated
Hardin County does not appear to have a local groundwater conservation district. That means private well owners have less local oversight than in counties that do have one.
Many Texas counties have a groundwater conservation district, or GCD. A GCD is a local agency that watches over underground water. It can require permits before you drill a new well. It can set limits on how much water you pump. It helps protect the local aquifer — the underground layer that holds the water. Hardin County does not appear on the Texas Water Development Board's list of active groundwater conservation districts.
Without a local GCD, private well owners in Hardin County still must follow state rules. Those rules cover how a well must be built and what the TCEQ — the Texas Commission on Environmental Quality — requires. But there is no local district to call about permits or water-use tracking. If you buy rural land and plan to use a private well, check the current rules with TCEQ and TWDB before you drill. Look at the TWDB's groundwater district map to confirm the latest district boundaries.
