Water Quality Reports

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

The Water Quality Consumer Confidence Report is 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.
