Radon tests reported for Sumter County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Sumter County over the 2008 to 2017 laboratory totals, with a median of 2.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Sumter County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Sumter 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).
Sumter County, Compared
Sumter County radon figures, compared
Calculated by Radon411CDC's largest figure for Sumter County rests on 2 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 2.4 pCi/L, with a middle value of 2.3 pCi/L.
The nearest counties with a figure are Tuscaloosa County (62 miles away) at 8.5%, Autauga County (91 miles away) at 17.1% and Jefferson County (101 miles away) at 10.7%. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%). EPA's 1993 map puts Sumter County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 58% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Sumter County, Geology
The ground under Sumter County
PredictedUSGS's geologic map splits Sumter County: 58.2% of its land is moderate radon potential and 41.8% low. The map puts 58.0% of Sumter County in the area it calls Inner Coastal Plain and 41.7% in Coastal Plain. USGS gives the first a radon index of 10, in the moderate band (9 to 11), and the second 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Inner Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Moderate | 10 | 58.0% |
| Coastal Plain | Marly sandy clay, chalk, and glauconitic sands. | Low | 7 | 41.7% |

Sumter County beside the ground around it
Across Alabama 14.3% of the land is rated high; none of Sumter County's is. Of the 7 counties that border it, 3 have more moderate-potential ground, Greene County the most at 100%.
