Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Saluda County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Saluda County, 2008 to 2017, laboratory

CDC holds 18 reported tests for Saluda County over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Saluda County beside the counties around it is how this page reads it.

What these figures count

Only 18 tests were reported to CDC for Saluda County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).

Saluda County, Compared

Saluda County radon figures, compared

Calculated by Radon411

CDC's largest figure for Saluda County rests on 28 tests over the 2005 to 2014 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 3.6 points and no rank or comparison is drawn from it. Results reached as high as 8.5 pCi/L, with a middle value of 0.8 pCi/L.

Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Newberry County reported the largest share at or above 4 pCi/L, 16.0%, and Greenwood County the smallest, 7.1%, with Aiken County at 13.3% and Lexington County at 12.5% between. Farther out, Laurens County (37 miles away) at 13.9%, Abbeville County (45 miles away) at 22.7% and Richland County (47 miles away) at 4.9% have figures too. Pooled across 46 South Carolina counties, 19.4% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Statewide for the same period, Oconee County reported the highest share (42.6%) and Florence County the lowest (0.0%). EPA's 1993 map puts Saluda County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 96% of the county's land low radon potential.

The ground under Saluda County

Predicted

Most of the ground under Saluda County is one class on USGS's geologic map: 96.4% of its land is low radon potential, with 3.6% moderate. The map puts 82.9% of Saluda County in the area it calls Carolina Slate Belt and 8.0% in Upper and Middle Coastal Plain, with 2 smaller areas beside them. USGS gives both a radon index of 8, in the low band (5 to 8).

Testing a home in Saluda County

No CDC figure names Saluda County; the nearest county with one, Newberry County (21 miles away), reported 16.0% of its tests at or above 4 pCi/L over the 2008 to 2017 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Saluda County.

Saluda County, Cities and towns

Cities and towns in Saluda County

The Census Bureau estimates 19,680 residents in Saluda County for July 1, 2025, 766 more than in 2020 (+4.0%). That works out to 43 people per square mile of land. Batesburg-Leesville, the largest place on its list (5,346 residents in all), extends beyond Saluda County, so no share of the total is worked out for it. Reported testing is thin here: 28 tests over 2005 to 2014, or 1.4 for every 1,000 residents (2025 estimate), where South Carolina as a whole comes to 3.9.

From Batesburg-Leesville to Ward, CDC publishes no figure by town: each reads Saluda County's.
