Around this lab: Crow Wing County, MN

• Private wells: about 36,558 people, 58% of Crow Wing County’s 63,428 residents (USGS, 2015); rank 8 of 87 counties in Minnesota by people on wells.
• At house sale: Crow Wing County has a septic system rule (Crow Wing County Land Use Ordinance (SSTS); section not read). 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 2,657 private-well users (95% range 1,973 to 3,570; 2010 base), rank 4 of 87 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 39% of 42,683 housing units were built before 1980, below the state share of 52%. 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): 2 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.
