Radon tests reported for Drew County, 2007 to 2016, laboratory
CDC holds 1 reported test for Drew County over the 2007 to 2016 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Drew County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Drew County over 2007 to 2016 (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: 2007 to 2016, laboratory. Measured data period: 2005 to 2016 (every CDC figure on file).
Drew County, Compared
Drew County radon figures, compared
Calculated by Radon411CDC's largest figure for Drew County rests on 1 test over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 0.1 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Pulaski County (88 miles away) at 6.8%, Saline County (91 miles away) at 31.9% and Garland County (107 miles away) at 45.8%. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%). EPA's 1993 map puts Drew County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Drew County, Geology
The ground under Drew County
PredictedUSGS's geologic map puts all of Drew County's mapped land in one class: low radon potential. The map puts 71.7% of Drew County in the area it calls West Gulf Coastal Plain and 28.3% in Mississippi Alluvial Plain. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| West Gulf Coastal Plain | Glauconitic, phosphatic, and carbonaceous sediments. | Low | 7 | 71.7% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 28.3% |

Drew County beside the ground around it
Across Arkansas 21.3% of the land is rated moderate; none of Drew County's is. None of the 6 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
