Pollution Prevention




Groundwater quality is important for maintaining human uses of groundwater and protecting the environment. The quality of groundwater is especially important for ensuring safe drinking water. The National Ground Water Association estimates that 49% of the U.S. population depends on groundwater for its drinking water supply from either a public source or private well. For more information on drinking water issues, see TGPC's Groundwater as Drinking Water Page.

Preventing contamination from occurring preserves groundwater quality. Removing contaminants from an aquifer can be costly and at times technologically infeasible. Pollution prevention is a much wiser, cheaper, and safer way of preserving the use of groundwater. To learn about groundwater quality in Texas, look at the TGPC's Joint Groundwater Monitoring and Contamination Report (see the TGPC Publications webpage for the current version).


Pollution Prevention for Public and Private Entities

The Texas Commission on Environmental Quality (TCEQ) has a host of programs for helping public and private entities reduce or eliminate pollution.
