Comprehensive water quality reports for major cities in Texas. Access Consumer Confidence Reports, contaminant data, EPA compliance information, and historical trends for water systems across the state.
Texas relies on a mix of surface water from rivers and reservoirs (40%) and groundwater from aquifers (60%). Major sources include the Trinity, Brazos, and Colorado Rivers, plus the Ogallala and Edwards Aquifers. Water availability varies significantly by region.
Major cities use conventional and advanced treatment including filtration, ozonation, and chlorination. Rural areas often rely on groundwater with minimal treatment. Many systems face aging infrastructure challenges.
Common in surface water systems, particularly during hot summer months. Formed when chlorine reacts with organic matter in source water.
Naturally occurring radium and uranium found in groundwater, particularly in West Texas and Gulf Coast regions.
Naturally occurring in groundwater, especially in rural areas. More common in Gulf Coast and parts of Central Texas.
Agricultural runoff and septic systems contribute to elevated nitrate levels, particularly in rural areas and the Texas Panhandle.
Present in older homes with lead service lines or plumbing. More common in systems with corrosive water or inadequate corrosion control.
Texas follows federal EPA regulations and adds state-specific requirements through the Texas Commission on Environmental Quality (TCEQ):
Enhanced monitoring requirements for lead and copper, with mandatory public education when action levels are exceeded.
New water systems must demonstrate technical, managerial, and financial capacity before approval to operate.
Required public notice within 24 hours for acute health risks and within 30 days for monitoring violations.

Texas water systems commonly monitor for disinfection byproducts (TTHMs and HAA5), radionuclides, nitrates, arsenic, and lead. Specific contaminants vary by region depending on water source, agricultural activity, and infrastructure age.
Water quality in Texas is regulated by the Texas Commission on Environmental Quality (TCEQ), working in conjunction with the federal EPA to ensure drinking water meets all federal and state standards.
