Lead in Water

Lead is a common metal found in lead-based paint, air, oil, household dust, food, water, and certain types of pottery porcelain and pewter. The most common source of lead in drinking water is the corrosion, or wearing away, of household plumbing fixtures and water system components that contain trace amounts of lead. To minimize risk, both the state and federal governments limit the amount of lead allowed in materials to deliver tap water, such as pipes, solder, faucets, and other plumbing fixtures.

Washington Water monitors for lead (and copper) in drinking water once every three years as required by law.  Samples are collected by customers from their kitchen tap.  The number of homes sampled is based on population served by the system, and specific EPA site-selection criteria are used to determine which homes can participate.  The results of the most recent round of Lead and Copper Monitoring is shown in your system's annual water quality report.  If you are unsure about lead levels in your home, or if your home was constructed before 1986 (when lead solder, used to join copper plumbing, was banned in Washington state), you may wish to take these precautions:
