City of Granbury

The sources of municipal water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels across land or underground, it dissolves naturally-occurring minerals and, in some cases, radioactive materials, and can pick up substances from animal presence or human activities.

The City of Granbury uses Surface water as its primary source. All municipal water, including bottled varieties, may contain at least small amounts of some contaminants. The presence of contaminants doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, contact the EPA's Safe Municipal Water Hotline at (800) 426-4791.

Possible contaminants in source water include:

• Microbial contaminants - viruses and bacteria from sewage treatment facilities, septic systems, agricultural operations, and wildlife
• Inorganic contaminants - salts and metals occurring naturally or from urban runoff, wastewater discharges, oil/gas production, farming, or mining
• Pesticides and herbicides - from agricultural sources, urban stormwater runoff, and residential usage
• Organic chemical contaminants - synthetic and volatile organics from industrial processes, petroleum production, gas stations, stormwater runoff, and septic systems
• Radioactive contaminants - naturally occurring or resulting from oil/gas production and mining

The EPA establishes regulations limiting contaminant levels in public water supplies, while FDA regulations set similar limits for bottled water to ensure public safety. Some contaminants may affect taste, color, or odor without posing health risks. For questions about water aesthetics, contact the system's office.

Certain populations may be more vulnerable to specific contaminants like Cryptosporidium. Infants, some elderly individuals, and those with compromised immune systems (such as cancer patients undergoing chemotherapy, organ transplant recipients, steroid treatment patients, and those with HIV/AIDS) should seek advice from healthcare providers about their water consumption.

If present, elevated lead levels can cause serious health problems, particularly for pregnant women and young children. Lead typically comes from service line materials and home plumbing components. While the utility provides quality water, they cannot control materials used in household plumbing. To minimize lead exposure, flush your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If concerned, consider water testing. Information about lead in water is available from the Safe Municipal Water Hotline or at http://www.epa.gov/safewater/lead.
