The main source of lead in drinking water is typically from household plumbing or components associated with service lines. We offer free lead testing to our water customers. If you are concerned about the levels of lead in your home, you can pick up a test kit and instructions at the 2nd floor reception desk at City Hall. For questions about lead testing or your drinking water, call the Water Treatment Plant at 503-635-0394.
