Around this lab: Washtenaw County, MI

• Private wells: about 66,798 people, 19% of Washtenaw County’s 358,880 residents (USGS, 2015); rank 9 of 83 counties in Michigan by people on wells.
• At house sale: Washtenaw County Health Department (Time of Sale Program) has a septic system and well rule (Washtenaw County Regulation for the Inspection of Residential Onsite Water and Sewage Disposal Systems at Time of Property Transfer). 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 5,310 private-well users (95% range 3,937 to 7,157; 2010 base), rank 13 of 82 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 53% of 159,782 housing units were built before 1980, below 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): 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.

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 Michigan certification program.
