Public Hearing: Action to Accept the 2019 Report on the City's Drinking Water Quality Program Relative to Public Health Goals

Report
BACKGROUND
Pursuant to the California Safe Drinking Water Act (California Health and Safety Code Section 116470), the City has been required to prepare a report on water quality, known as the Public Health Goals (PHG) report, every three years since 1998. In line with the three-year reporting cycle, the City must, at this time, hold a public hearing to accept the 2019 Report on the City's Drinking Water Quality Report Relative to Public Health Goals ("2019 PHG Report") and respond to public comment regarding the PHG Report.

The attached report addresses the presence of constituents adopted by OEHHA. Where the OEHHA has not adopted a PHG for a currently regulated contaminant, the report uses the existing Maximum Contaminant Level Goal (MCLG) adopted by the USEPA.
