Maybe you are researching your own long-term health after years on the same Oregon tap, or maybe you typed in "Oregon DEQ" and landed somewhere unexpected. Either way, the agencies behind the figures below are the Oregon Department of Environmental Quality and the Oregon Health Authority's Drinking Water Services program, which together watch PFAS in the state's public systems. The numbers come from federal monitoring, not from any one utility. They do not pass judgment on a single home. They are the public record, set out so you can read it without panic and decide what is worth reviewing when evaluating an address.
EPA's UCMR 5 program (2021–2024) tested 46 public water systems in Oregon for 29 PFAS compounds; 0 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 0% detection rate). Detections vary by water system — check the utility serving a specific Oregon address.
Oregon splits the work in a way that trips up newcomers: the Oregon Department of Environmental Quality (DEQ) handles broad environmental protection, while drinking water itself is run by the Oregon Health Authority's Drinking Water Services program. On PFAS, Oregon has been among the states leaning toward health advisory and notification levels rather than a single hard enforceable ceiling distinct from the federal rule, so for most residents the April 2024 federal limits remain the operative standard. Two acronyms for one glass of water is a lot, but it also means two offices are watching, and you can read what each reports rather than guess.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Oregonserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Looking at a specific Oregoncity? Each page below pulls the same federal data narrowed to that water system — useful whether you're relocating, buying, organizing your neighborhood around getting cleaner water, or just trying to find out what's in the tap and what's around you.
Before the figures above harden in your mind, a few caveats on what they cover. The federal round behind them sampled 29 PFAS compounds at public systems serving more than roughly 3,300 people, between 2021 and 2024. Smaller rural systems sit below that line, private wells were never required to test at all, and a 2022 reading describes that year, not necessarily the water running today. For a private well, Oregon's drinking-water guidance through the Health Authority is a better first stop than any statewide system average. The fact that protection and drinking water answer to two different agencies here (DEQ and the Health Authority) is its own small civics lesson.
Military sites deserve their own careful read, and Oregon hosts long-standing aviation and Guard installations. For years, a firefighting foam called AFFF was used in training, and it carried the very PFAS compounds now drawing scrutiny. These chemicals resist breaking down and can move through groundwater past any property boundary, which is why nearby installations matter to a water conversation. If you or someone in your family served, the installations listed above are offered as context, not alarm, so you can see where groundwater attention has concentrated.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 46 public water systems in Oregon; 0 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
Oregon has tended toward health advisory and notification levels rather than a separate enforceable limit distinct from the federal rule. For residents on public systems, the operative standard is the April 2024 federal rule, administered through the Oregon Health Authority's Drinking Water Services program: 4 parts per trillion for PFOA and PFOS, and 10 for PFHxS, PFNA, and GenX.
Oregon divides the work between the Department of Environmental Quality (DEQ), which handles broad environmental protection, and the Oregon Health Authority's Drinking Water Services program, which oversees public drinking water. PFAS oversight largely tracks federal limits, with state guidance and notification levels layered on top.
The Oregon Department of Environmental Quality (DEQ) is the state agency for air, land, and water quality. Notably, it does not run drinking water directly; that falls to the Oregon Health Authority, which is the office to look to for tap-water standards.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any Oregon address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.
In April 2024 the EPA set the first enforceable federal limits for PFAS in drinking water: 4 parts per trillion for PFOA and PFOS, and 10 ppt each for PFHxS, PFNA, and HFPO-DA (GenX), plus a Hazard Index for certain mixtures. Public water systems must complete initial monitoring by 2027 and come into compliance after that.
No. The federal limits apply to public water systems. Private well owners are responsible for their own testing and treatment, which is especially worth doing near a known PFAS source like a military base or industrial site.
State numbers tell you the pattern. An address report tells you what's actually in the water at yourkitchen sink — the matched utility, the PFAS detections on file, and every military or industrial source nearby. Whether it's for your family, your neighbors, or peace of mind.
