About Us
UNDERSTANDING YOUR WATER SOURCES
San Antonio's municipal water comes from various sources including groundwater from the Edwards, Carrizo, Trinity and Wilcox aquifers, and surface water from Canyon Lake. Understanding these sources helps residents make informed decisions about their water quality.
POTENTIAL CONTAMINANTS IN SOURCE WATER
All water sources - whether from tap or bottle - can contain various contaminants:
- Microbial contaminants: Viruses and bacteria from sewage systems, agricultural operations, and wildlife
- Inorganic contaminants: Naturally-occurring salts and metals, or those resulting from urban runoff and industrial discharges
- Pesticides and herbicides: From agricultural activities, urban runoff, and residential uses
- Organic chemicals: By-products of industrial processes, petroleum production, gas stations, and septic systems
- Radioactive materials: Either naturally-occurring or from oil/gas production and mining
WATER QUALITY MONITORING
SAWS regularly tests water quality, sampling 360 distribution sites monthly for bacteria. In 2017, no E. coli was detected in the municipal supply. The Texas Commission on Environmental Quality conducts Source Water Susceptibility Assessments to identify potential contamination risks.
SPECIAL HEALTH CONSIDERATIONS
Some residents may be more vulnerable to certain contaminants, including immunocompromised individuals undergoing chemotherapy, organ transplant recipients, those on steroid treatments, and people with HIV/AIDS. These individuals should seek specific advice from healthcare providers about municipal water consumption.
LEAD IN DRINKING WATER
If present, elevated lead levels can cause serious health problems, particularly for pregnant women and young children. Lead typically comes from service lines and home plumbing materials. To minimize potential exposure, flush your tap for 30 seconds to 2 minutes before using water for drinking or cooking, especially after periods of non-use.
