Water Quality

Water Standards

Individual water companies do not decide what constitutes "safe" water. All public water supplies in California must meet stringent quality standards established by both federal and state regulators. In California, standards are enforced by the California Department of Public Health (CDPH).

On the federal level, the Safe Drinking Water Act of 1974 and its amendments regulate the quality of our water supply. The United States Environmental Protection Agency (USEPA) has set standards and monitoring requirements for water utilities.

CVWD tests for chemicals that could be present in our drinking water supply. CVWD completes bacteriological samples from sampling stations within our district boundaries. We also run miscellaneous tests throughout the year to monitor water quality conditions within our own distribution system to ensure that we provide the highest quality water to all of our customers.


Most of our customers are not aware of how much regulatory compliance costs. However, it is worth the investment to ensure that you receive good quality water at all times.
