Around this lab: Clark County, NV

• Private wells: about 98,399 people, 5% of Clark County’s 2,114,801 residents (USGS, 2015); rank 1 of 17 counties in Nevada 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.
• Arsenic above 10 µg/L (USGS model): about 5,783 private-well users (95% range 4,832 to 6,888; 2010 base), rank 2 of 17 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 18% of 948,995 housing units were built before 1980, below the state share of 22%. 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): 30 public systems 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 Nevada certification program.
