Hesperia Water District

Understanding Your Municipal Water Supply

Municipal water (both tap water and bottled water) comes from various sources including rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels across land or through ground layers, it dissolves naturally-occurring minerals and sometimes radioactive materials, while also potentially collecting substances from animal presence or human activity.

Currently, all municipal water provided to Hesperia residents originates from the groundwater aquifer. Potential contaminants in source water include:

• Microbial contaminants such as viruses and bacteria from sewage treatment facilities, septic systems, agricultural operations, and wildlife
• Inorganic contaminants including salts and metals that may occur naturally or result from urban runoff, industrial discharge, oil and gas production, mining, or farming
• Pesticides and herbicides from various sources including agriculture, urban stormwater runoff, and residential usage
• Organic chemical contaminants, including synthetic and volatile organics, which are byproducts of industrial processes, petroleum production, gas stations, urban runoff, and septic systems
• Radioactive contaminants that can occur naturally or result from oil and gas production and mining activities

To ensure tap water safety, the U.S. Environmental Protection Agency (USEPA) and State Water Resources Control Board (SWRCB) establish regulations limiting contaminant levels in water provided by the Water District. Hesperia Water District actively protects the city's water supply with enhanced security features at each source location.

1. How often is municipal water tested in Hesperia?

   Water quality is monitored continuously, with comprehensive testing conducted multiple times annually.

2. What causes the hard water in Hesperia?

   The local groundwater naturally contains high levels of calcium and magnesium minerals as it passes through underground rock formations.

3. Is Hesperia tap water safe to drink?

   Yes, the water meets safety standards set by regulatory agencies, though some may prefer filtration due to taste preferences or concerns about specific contaminants.
