Around this lab: Clatsop County, OR
- Private wells: about 226 people, 1% of Clatsop County’s 37,831 residents (USGS, 2015); rank 36 of 36 counties in Oregon by people on wells.
- At house sale: Statewide (Domestic Well Testing Act) has a well_test rule (ORS 448.271; OAR 333-061-0305 to 0335). What it requires
- EPA radon zone (indoor air): Zone 2: moderate potential (average indoor radon may be between 2 and 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
- Older homes (Census ACS 2020–2024): 58% of 23,395 housing units were built before 1980, above the state share of 49%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
- PFAS in public water nearby (public supply, not your well): 3 public systems serving this county reported EPA UCMR 5 results; 0 had a PFOA or PFOS sample at or above 4.0 ng/L.
County figures describe where the lab is, not the lab. Sources: USGS 2015 water use and 2017 arsenic estimates, EPA radon zones, Census ACS table B25034 (2020–2024), EPA UCMR 5 (2023–2026); details and links on the sources page.
Before you send a sample
Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Oregon certification program.
