Public Health Goal

Report on Water Quality Relative to Public Health Goals

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 which have a California primary drinking water standard and for which either a PHG or MCLG has been set are to be addressed.
