Pasadena Water and Power Reports to Pasadena Council Drinking Water Committee – Pasadena Now

Pasadena Water and Power submits its 2022 Public Health Goals (PHG) report to the Municipal Services Committee of the City Council on Tuesday, November 8, as required by the California Environmental Protection Agency under the California Health and Safety Code, community water services like PWP.

City Council is expected to hold a public hearing and receive public comment on the PWP-recommended 2022 PHG report in early December, before allowing it to be forwarded to CalEPA.

The PHG report describes what is in Pasadena’s drinking water: the “presence of constituents” – including contaminants – in the treated water of PWPs that have concentrations above the PHG levels established by CalEPA and maximum contaminant level (MCLG) objectives established by the United States Environmental Protection Agency (EPA). These goals are the level of a contaminant in drinking water below which there is no known or expected health risk.

The report includes a description of the types of public health risks, methods of treatment, if any, and associated estimated costs.

Per CalEPA requirements, PWP should provide the public with an opportunity to review and comment on the PHG report. The city council is also required to accept and approve the PHG report.

Besides the PHG report, PWP is also required to publish a Consumer Confidence Report (CCR) on an annual basis and distribute it to its clients. PWP released its 2021 CCR on July 1. It is accessible via and is also available in the PWP water quality section at

Pasadena derives more than 60% of the city’s water supply from imported water purchased from the Metropolitan Water District (MWD) of Southern California, while the remainder comes from local groundwater sources.

The city maintains eighteen groundwater wells, nine of which are considered “inactive” by the Drinking Water Division (DDW) of the State Water Resources Control Board of California (SWRCB). The city also has five interconnections with MWD and several others with other water retailers.

In the PHG report for the city council, PWP said the city’s drinking water meets all California SWRCB and U.S. Environmental Protection Agency (EPA) DDW drinking water standards established to protect public health. All constituents that were identified in the report are below the Maximum Contaminant Level (MCL) after treatment through the city’s Monk Hill Treatment System (MHTS) or other rigorous blending plans. Reducing constituents further would amount to an additional treatment process, which would be costly for the city, PWP said.
