Around this lab: Humboldt County, CA

• Private wells: about 9,620 people, 7% of Humboldt County’s 135,727 residents (USGS, 2015); rank 38 of 58 counties in California by people on wells.

• 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 129 private-well users (95% range 88 to 180; 2010 base), rank 47 of 58 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 60% of 62,883 housing units were built before 1980, above the state share of 56%. 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): 10 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 California certification program.
