Texas Tap Water Quality

EPA water quality data for 150 community water systems serving 3,209,118+ people in Texas. Click any system to see violations, lead testing results, and a safety grade.

Texas has the second-most community water systems in the country, sourcing from reservoirs, the Edwards and Ogallala Aquifers, and desalination plants. Naturally occurring arsenic, radium, and fluoride are found in many groundwater sources, particularly in West Texas. Water hardness varies widely, from soft in East Texas to very hard in the Hill Country and Permian Basin.
