About Us
Green Valley Special Utility District (GVSUD) provides water service through purchased surface water, purchased groundwater, and locally produced groundwater sources. As water travels over land or through soil, it naturally dissolves minerals and can pick up substances from animal presence or human activities.
All municipal water, including bottled varieties, typically contains at least small amounts of contaminants. The presence of these substances doesn't necessarily indicate a health risk. For detailed information about contaminants and potential health effects, residents can contact the EPA's Safe Drinking Water Hotline at (800) 426-4791.
Certain populations may have heightened vulnerability to specific microbial contaminants like Cryptosporidium. This includes infants, some elderly individuals, and those with compromised immune systems such as cancer patients undergoing chemotherapy, organ transplant recipients, people on steroid treatments, and individuals with HIV/AIDS. These residents should seek advice from healthcare providers about their drinking water.
If present, elevated lead levels can cause serious health concerns, particularly for pregnant women and young children. Lead primarily enters drinking water through plumbing materials. While GVSUD provides high-quality water, they cannot control materials used in household plumbing. Residents can minimize lead exposure by flushing taps for 30 seconds to 2 minutes before using water for consumption if it has been sitting for several hours.
Source water contaminants may include:
- Microbial contaminants (viruses, bacteria) from sewage treatment, septic systems, agricultural operations, and wildlife
- Inorganic contaminants (salts, metals) from natural sources, urban runoff, industrial wastewater, oil/gas production
- Pesticides and herbicides from agriculture, urban runoff, and residential uses
- Organic chemical contaminants from industrial processes, petroleum production, gas stations, and septic systems
- Radioactive contaminants that occur naturally or result from oil/gas production
The EPA sets regulations limiting contaminant levels in public water systems, while FDA establishes similar limits for bottled water. Some substances in drinking water may affect taste, color, or odor without necessarily causing health concerns.
