Many people in California considering buying water coolers or dispensers are concerned about the quality of the local drinking water.
Suppliers of drinking water provide reports (also called consumer confidence reports) providing the source of drinking water in California.
The EPA has a source water protection case study available for the public water supply of Contra Costa Water District
The Environmental Protection Agency recommends that if your drinking water comes from a private well, you have the water tested once a year. Well owners are responsible for their water's safety and each state provides a list of certified commercial laboratories that test drinking water.
