Around this lab: New Hanover County, NC

• Private wells: about 56,602 people, 26% of New Hanover County’s 220,358 residents (USGS, 2015); rank 9 of 100 counties in North Carolina by people on wells.
• County health department: New Hanover County Health Department, Environmental Health Services samples wells; bacteria test Water Sample - Bacteriological $140.00 source (read 14 Nov 2026).

• 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.
• Arsenic above 10 µg/L (USGS model): about 1,492 private-well users (95% range 1,006 to 2,224; 2010 base), rank 19 of 100 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 31% of 120,050 housing units were built before 1980, below the state share of 34%. 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): 8 public systems serving this county reported EPA UCMR 5 results; 1 had a PFOA or PFOS sample at or above 4.0 ng/L.
