How the South Carolina list marks public samples (whole list). Not stated per lab. SCDES's well-testing page tells well owners: "For Volatile Organic Chemicals, Herbicides, Pesticides, Other Synthetic Organic Parameters, please contact a Commercial Laboratory." It names no lab, and CELMAPP does not say which labs take samples from homeowners.
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 uranium in South Carolina
Uranium comes from rock, mainly harms the kidneys, and often shows up first as a gross alpha radioactivity number. Read our uranium explainer.
South Carolina guidance that mentions uranium:
- Clemson Extension says comprehensive testing should be done after a well is installed and whenever recent results are not available. That covers arsenic, chloride, copper, fluoride, hardness, iron, lead, manganese, nitrate, pH, radium, sodium, sulfate, total coliform bacteria, total dissolved solids (TDS) and uranium. It recommends annual testing for priority parameters, including bacteria, nitrates, TDS and pH, and a monthly visual check for changes in turbidity, color, odor or taste. [1]
About 1,182,721 people in South Carolina 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: South Carolina.
