If your residence or business is connected to a Public Water System, the service provider is required by law to follow strict health standards set by State and Federal agencies. Public water utilities are mandated by State law to ensure 100% of the drinking water delivered is safe to drink.  Additionally, the State can shut down a system if contaminant levels exceed drinking water standards.   When a private well is the source of drinking water, only a water test can reveal if the water is safe to drink. Many contaminants are odorless and tasteless.   For additional information on water quality in the city of Chowchilla please see the Water Quality Consumer Report.
