Iowa DNR lab type: Public. LabCert lists 2 drinking-water analytes this lab is certified for. Iowa DNR's program page says private well owners can get free testing once a year (nitrate, bacteria, arsenic and manganese) through the Grants to Counties program, which "is run by your county health department". Ask this department whether it takes part.

Around this lab: Dubuque County, IA

• Private wells: about 16,200 people, 17% of Dubuque County’s 97,125 residents (USGS, 2015); rank 3 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 323 private-well users (95% range 254 to 407; 2010 base), rank 40 of 99 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 63% of 43,288 housing units were built before 1980, about the same as 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): 3 public systems serving this county reported EPA UCMR 5 results; 1 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.

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 Iowa certification program.
