Around this lab: Pierce County, WA

• Private wells: about 65,912 people, 8% of Pierce County’s 843,954 residents (USGS, 2015); rank 4 of 39 counties in Washington by people on wells.
• At house sale: Tacoma-Pierce County Health Department has a septic system rule (Tacoma-Pierce County Health Department Health Code (chapter not stated on page)). 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 1,738 private-well users (95% range 1,366 to 2,232; 2010 base), rank 10 of 37 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 42% of 369,709 housing units were built before 1980, about the same as the state share of 43%. 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): 24 public systems serving this county reported EPA UCMR 5 results; 8 had a PFOA or PFOS sample at or above 4.0 ng/L.

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.
