Around this lab: Multnomah County, OR

  • Private wells: about 30,692 people, 4% of Multnomah County’s 790,294 residents (USGS, 2015); rank 7 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.
  • Arsenic above 10 µg/L (USGS model): about 1,271 private-well users (95% range 962 to 1,697; 2010 base), rank 9 of 36 in the state. A screening estimate, not a measurement of any well.
  • Older homes (Census ACS 2020–2024): 60% of 371,179 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): 11 public systems serving this county reported EPA UCMR 5 results; 2 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 Washington certification program.
