The Portland Water Bureau continues to deliver clean and safe drinking water that meets or surpasses drinking water standards to nearly a million customers, according to our annual water quality report. And here’s how we know: We conduct more than 11,000 tests per year to track more than 200 potential contaminants. Tests are conducted throughout the system, all the way from the source to people’s taps.
Every year, the Portland Water Bureau issues the Drinking Water Quality Report to explain what’s in your water and what we do to keep it safe and flowing to your tap.
"We have some of the best drinking water in the world,” said Interim Portland Water Bureau Director Quisha Light. “And that’s thanks to decades of careful planning and ongoing investment in projects designed to keep our water safe and accessible.”

Public health is our top priority
Portland’s drinking water is tested and safe, every step of the way. This starts with our two high-quality sources, which are the two largest drinking water sources in the state: the Bull Run Watershed and the Columbia South Shore Well Field. Water Bureau staff test water from many locations around our water system, including our water sources, our treatment facilities, and around town.
This report includes test results for all known health-related contaminants detected in 2024. If a known health-related contaminant is not listed in this report, it was not detected in our drinking water. We are proud to share that we tested for 29 types of PFAS (perfluoroalkyl and polyfluoroalkyl substances) in 2024 and did not detect PFAS in our drinking water.
The report also makes it easy for you to get updates on our excellent water sources, wise water system investments, and your drinking water.

Investing to maintain reliable service
We are investing in system resilience, in part by bringing a new Bull Run Treatment filtration facility online. We achieved an important project milestone and started construction of the new water filtration facility and pipelines last year. A project this size takes multiple years to build, and keeping our momentum through construction is critical to having these water system improvements in place by September 2027.
“We continue to replace aging pipes, pumps, and valves to keep delivering reliable, safe drinking water,” said Light. “We are also committed to evolving our operations to respond to climate change and reduce our carbon footprint.”
