Water Quality
Interested in learning more about your drinking water quality? Have a water quality concern? Read on for helpful information.
Lake Oswego currently meets or exceeds all federal and state requirements for water quality testing. PFAS is an emerging issue that all water providers and systems across the nation are experiencing. The City is closely tracking news about detections of PFAS in drinking water around the country, as well as the EPA’s newly proposed PFAS drinking water regulations. We are committed to protecting public health.
Fortunately, Lake Oswego and Tigard’s drinking water is at low risk for PFAS, and PFAS have not been detected in our drinking water from the Clackamas River.
Clean drinking water is an essential resource we rely on every day. Providing residents and businesses in Lake Oswego with safe, dependable, high-quality water is our top priority.
Lake Oswego’s tap water meets or exceeds every State and Federal standard for safe drinking water. Get to know your drinking water by reviewing the latest 2023 Water Quality Report!
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.
Cyanotoxins (produced by blue green algae) were detected in Salem’s drinking water in 2018. Lake Oswego’s drinking water is safe to drink. Read on for more information.
