About TGPC

Why a Committee?

Groundwater is vital to the health and economy of Texas. In 1999, groundwater provided 58% of the water used in Texas. Texas groundwater is used as drinking water, irrigation for crops, and has numerous industrial functions. Managing such an essential resource requires a lot of coordination. Nine state agencies and an association of groundwater districts manage aspects of groundwater. Together, these entities comprise the Texas Groundwater Protection Committee (TGPC).

Created by the Texas Legislature's House Bill 1458 in 1989, the TGPC bridges the gap between state groundwater programs, improves coordination between member agencies, and works to protect groundwater as a vital resource. A brochure (TCEQ publication GI-088) and a flyer describing the TGPC are available.

Committee Goals

Texas Water Code, Title 2, Subtitle D, Chapter 26, Subchapter J, Section 401 gives the TGPC its mission, sets non-degradation of the state's groundwater resources as the goal for all state programs, and asserts that groundwater be kept reasonably free of contaminants that interfere with its present and potential uses.

The TGPC implements the State's groundwater protection policy which:

  • calls for non-degradation of groundwater
  • requires that pollution discharges, waste disposal, and other regulated activities not harm public health or impair current or potential groundwater use
  • recognizes the variability between aquifers
  • acknowledges the importance of water quality
  • balances the protection of the environment and the long-term economic health of the state
  • recognizes the use of the best professional judgment of the responsible state agencies to implement the policy.
