Around this lab: Clackamas County, OR

• Private wells: about 74,835 people, 19% of Clackamas County’s 401,515 residents (USGS, 2015); rank 1 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 3: low potential (average indoor radon may be less than 2 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 1,375 private-well users (95% range 1,015 to 1,830; 2010 base), rank 8 of 36 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 44% of 174,323 housing units were built before 1980, below 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): 16 public systems serving this county reported EPA UCMR 5 results; 2 had a PFOA or PFOS sample at or above 4.0 ng/L.
