Around this lab: Hamilton County, IA

  • Private wells: about 3,648 people, 24% of Hamilton County’s 15,190 residents (USGS, 2015); rank 55 of 99 counties in Iowa by people on wells.
  • At house sale: Statewide has a septic system rule (Iowa Code 455B.172(11); 567 IAC Chapter 69). 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 930 private-well users (95% range 724 to 1,165; 2010 base), rank 7 of 99 in the state. A screening estimate, not a measurement of any well.
  • Older homes (Census ACS 2020–2024): 79% of 7,040 housing units were built before 1980, above the state share of 62%. 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.

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.
