Water Quality Reports
Our Water Quality Team is Working 24/7
Our state certified professionals monitor your drinking water quality every day and around-the-clock.
They conduct thousands of tests each year to ensure the quality of your water to incredible levels of accuracy – a fraction of a part per billion in some instances
Certain tests are conducted at our own state-certified laboratory; independent laboratories with the most sophisticated equipment available carry out the rest.

Public Health Goal Report
Provisions of the California Health and Safety Code, Title 22, Section 116470, specify that every three years water utilities larger than 10,000 service connections are required to prepare a special report if their water quality measurements have exceeded any Public Health Goals (PHGs).
PHGs are non-enforceable goals established by the California Environmental Protection Agency's (CalEPA) Office of Environmental Health Hazard Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a constituent, the water suppliers are to use the Maximum Contaminant Level Goals (MCLGs) adopted by the United States Environmental Protection Agency (USEPA). Constituents that have a California primary drinking water standard and for which either a PHG or MCLG has been set are to be addressed.

Monitoring Violation
A monitoring violation is issued when water systems do not collect or report samples by the deadline required by the State of California. In 2025, the District was required to sample for hexavalent chromium by April 1, 2025, but we collected samples between May and June 2025 instead. The maximum contaminant level for Hexavalent Chromium is 10 parts per billion (ppb), and the District’s samples were all at or below 1.2 ppb (1 ppb is equivalent to one drop of water in an Olympic sized swimming pool). All water samples met drinking water standards.
