Around this lab: Ingham County, MI

• Private wells: about 5,089 people, 2% of Ingham County’s 286,085 residents (USGS, 2015); rank 73 of 83 counties in Michigan by people on wells.
• At house sale: Ingham County Health Department (Point of Sale Regulation) has a septic system and well rule (Ingham County Sanitary Code, Point of Sale Regulation (2006)). 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 1,922 private-well users (95% range 1,585 to 2,329; 2010 base), rank 31 of 82 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 65% of 126,232 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): 6 public systems serving this county reported EPA UCMR 5 results; 0 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 Ohio certification program.
