  • Water Quality Reports

    The California State Water Resources Control Board, Division of Drinking Water (DDW) requires Pasadena Water and Power to provide annual water quality testing results to its consumers.

    These reports are designed to inform you about drinking water quality and to consider the challenges of delivering a safe and protected supply of drinking water. We encourage you to read the reports carefully to familiarize yourself with the protection and conservation of Pasadena's valuable water resources.

    PWP is required by DDW to test well water for organic chemicals, minerals, metals, and bacteria. PWP is also required to test regularly for bacteria and total trihalomethanes in our distribution system. Lead and copper are tested in tap water from selected residences. The Metropolitan Water District of Southern California (MWD), our supplier of imported water, is responsible for testing their treated water.

  • Water Quality Notice: 1,2,3-Trichloropropane Detected in Two PWP Water Wells

    In February 2014, PWP confirmed trace amounts of 1,2,3-Trichloropropane (1,2,3-TCP) in two of its wells. It was detected at a concentration of 9 parts per trillion in PWP’s Woodbury Well, on the east side of the City, and at 7 parts per trillion in the Bangham Well, on the west side of the City at the City Yards. The Woodbury Well currently remains in service and the Bangham Well is temporarily out of service due to construction.

    The 1,2,3-TCP does not pose a significant health risk to PWP’s water customers at the levels detected locally, according to the Pasadena Public Health Department.
