How the West Virginia list marks public samples (whole list). OLS's list is a set of certificates issued under West Virginia 64CSR 3-13 (public drinking water) and does not say which labs take samples from private well owners. OLS's own pamphlet for household wells tells well owners to call OLS for coliform bacteria and chemistry sampling, so OLS's two certificates (Chemistry, Microbiology) are marked as taking homeowner samples; for every other lab it is not stated.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for arsenic in West Virginia
Arsenic is invisible, tasteless and mostly natural, and it comes in two forms that respond very differently to treatment. Read our arsenic explainer.
USGS estimates that the most private-well users with arsenic above 10 µg/L, EPA's limit for public water, live in Hampshire County, Morgan County and Berkeley County (about 1,452 people in Hampshire County, 2010 base year). USGS describes this kind of estimate as useful "for broad screening of the population at risk", so it says nothing certain about any one well. [1]

USGS model estimate for broad screening, not a measurement of any well. Only a test tells you about your own well. Source: USGS, Estimated county level domestic well population with arsenic greater than 10 micrograms per liter (Ayotte, Medalie and Qi, 2017), accessed 2026-11-01.
About 391,591 people in West Virginia used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [2] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: West Virginia.
