Around this lab: Berks County, PA

• Private wells: about 152,926 people, 37% of Berks County’s 415,271 residents (USGS, 2015); rank 6 of 67 counties in Pennsylvania 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.
• Arsenic above 10 µg/L (USGS model): about 2,842 private-well users (95% range 1,976 to 4,162; 2010 base), rank 11 of 67 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 64% of 171,580 housing units were built before 1980, below the state share of 67%. 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): 25 public systems serving this county reported EPA UCMR 5 results; 13 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 Pennsylvania certification program.
