PFAS in Oregon tap water

In EPA's 2024 UCMR 5 testing, 6 cities of 66 had a regulated PFAS (PFOA, PFOS or PFHxS) above the new federal limit, and PFAS were detected at any level in 8.

Lead in Oregon tap water

Utilities report lead as the 90th-percentile result from sampled home taps. 48 of 66 Oregon cities reported a value above zero, and 0 cities were above the 15 µg/L federal action level. Lead usually enters water from a building's own pipes, so a test at your tap is the only way to know what you drink.

Frequently asked questions

How does Oregon tap water compare across cities?

PurityMap ranks 66 cities in Oregon by their Purity Score, computed only from contaminants measured in the published EPA record. Medford has the highest published score (100/100). The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Oregon cities have PFAS above the federal limit?

6 cities of 66 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Hermiston (PFOS 12 ng/L), Klamath Falls (PFOS 9.5 ng/L), Bend (PFOA 7.9 ng/L). PFAS were detected at any level in 8.

Is there lead in Oregon tap water?

Utilities report lead as a 90th-percentile result from home taps. 48 of 66 Oregon cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

Limits, sources and corrections

A statewide page cannot tell you what reaches a specific address. Water quality varies by supplier, sampling period and household plumbing; open a city report for the evidence behind a local result.

Sources: EPA UCMR 5 (PFAS, 2024), SDWIS Lead and Copper Rule 90th-percentile results and health-based violations, and utility Consumer Confidence Reports where on file. Every city report links its dated source records.
