Around this lab: Fairfield County, CT

• Private wells: about 179,447 people, 19% of Fairfield County’s 948,053 residents (USGS, 2015); rank 2 of 8 counties in Connecticut by people on wells.

• 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.

• PFAS in public water nearby (public supply, not your well): 13 public systems serving this county reported EPA UCMR 5 results; 11 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 Connecticut certification program.
