Radon tests reported for Pocahontas County, 2008 to 2017, laboratory
CDC holds 16 reported tests for Pocahontas County over the 2008 to 2017 laboratory totals, with a median of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pocahontas County beside the counties around it is how this page reads it.
What these figures count
Only 16 tests were reported to CDC for Pocahontas 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).
Pocahontas County, Compared
Pocahontas County radon figures, compared
Calculated by Radon411CDC's largest figure for Pocahontas County rests on 16 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 6.1 pCi/L, with a middle value of 1.0 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Greenbrier County reported the largest share at or above 4 pCi/L, 52.3%, and Pendleton County the smallest, 30.9%, with Randolph County at 36.4% between. Farther out, Harrison County (69 miles away) at 36.4%, Grant County (69 miles away) at 9.8% and Taylor County (69 miles away) at 28.1% have figures too. Pooled across 55 West Virginia counties, 37.5% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Morgan County reported the highest share (58.1%) and Grant County the lowest (9.8%). EPA's 1993 map puts Pocahontas County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 53% of the county's land moderate radon potential.

The ground under Pocahontas County
PredictedUSGS's geologic map splits Pocahontas County: 53.3% of its land is moderate radon potential and 46.7% high. The map puts 47.6% of Pocahontas County in the area it calls Southern Appalachian Valley and Ridge and 46.6% in Northern Appalachian Valley and Ridge, with one smaller area beside them. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 14, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Southern Appalachian Valley and Ridge | Ordovician-Mississippian shale, siltstone, sandstone, limestone. | Moderate | 11 | 47.6% |
| Northern Appalachian Valley and Ridge | Sandstone ridges, shale and limestone valleys, mostly Devonian | High | 14 | 46.6% |
| Eastern Allegheny Plateau and Mtns | Devonian-Pennsylvanian shale, siltstone, sandstone, minor limestone and coal | Moderate | 10 | 5.7% |
