Pasadena’s drinking water meets or exceeds all state and federal standards, annual report finds
The City of Pasadena’s drinking water once again meets or exceeds all state and federal requirements, according to the 2024 Annual Drinking Water Quality Report released Wednesday. The report, which covers the 2023 calendar year, details the sources, treatment, composition, and quality of the City’s water supply, as well as information on contaminants and health effects. In 2023, Pasadena Water and Power provided approximately 23,800 acre-feet or 8.6 billion gallons of water to serve more than 160,000 customers. About two-thirds of this supply was purchased from the Metropolitan Water District of Southern California, which sources water from the Colorado River and the State Water Project in Northern California. The remaining supply came from the City’s groundwater wells in the Raymond Basin aquifer.
