How does PWP test the water?
PWP is required by state and federal law to regularly test the water. We have a crew of field and laboratory personnel who sample and test the water every day of the year, including weekends and holidays. The water is tested with varying frequency at approximately 300 locations around the City. The water meets all state and federal drinking water standards. There are over 170 different constituents in the water, which are tested by PWP. The amount of each constituent allowed in the water and frequency with which we test for each constituent varies greatly and is regulated by the State of California Department of Health Services (DHS) and by the United States Environmental Protection Agency (USEPA). PWP monitors state regulations as to water quality and assuring that Pasadena water always meets or exceeds federal and state standards. Customers can review the PWP Annual Drinking Water Quality Report so they can feel confident that the stringent testing and tough water quality guidelines
