Around this lab: Queens County, NY

• Private wells: about 0 people, 0% of Queens County’s 2,339,150 residents (USGS, 2015); rank 57 of 62 counties in New York by people on wells.

• EPA radon zone (indoor air): Zone 3: low potential (average indoor radon may be less than 2 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Older homes (Census ACS 2020–2024): 83% of 910,206 housing units were built before 1980, above the state share of 74%. 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): 1 public system 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 Pennsylvania certification program.
