Around this lab: Goodhue County, MN

• Private wells: about 15,435 people, 33% of Goodhue County’s 46,435 residents (USGS, 2015); rank 27 of 87 counties in Minnesota by people on wells.
• At house sale: Goodhue County has a septic system rule (Goodhue County SSTS Ordinance (county forms)). What it requires

• EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 540 private-well users (95% range 424 to 691; 2010 base), rank 49 of 87 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 59% of 21,167 housing units were built before 1980, above 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): 4 public systems serving this county reported EPA UCMR 5 results; 0 had a PFOA or PFOS sample at or above 4.0 ng/L.
