Texas Commission on Environmental Quality

The Texas Commission on Environmental Quality (TCEQ) is the state agency responsible for environmental protection and enforcement in Texas. It publishes air quality measurements from monitoring stations across the state, water quality data including surface water and groundwater contamination reports, hazardous waste facility permits, and environmental compliance records. The agency maintains databases on permitted industrial facilities, landfills, and superfund sites. TCEQ data feeds into national EPA systems and is used by researchers, local governments, and the public to track environmental conditions and industrial activity.
