Calculated by Radon411

Taylor County's 32 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.2 pCi/L and a maximum of 12.6 pCi/L, and 28.1% reached 4 pCi/L. West Virginia as a whole (55 West Virginia counties, pooled) comes to 37.5%: 9.4 points higher than here.

Among its state's counties it ranks 18th of 27 West Virginia counties with 30 or more tests for the same period. Statewide for the same period, Morgan County reported the highest share (58.1%) and Grant County the lowest (9.8%).

Below the action level, 13 tests (40.6%) came in under 2 pCi/L, against 37.7% statewide, and 10 tests (31.3%) fell between 2 and 4, against 24.7% statewide. CDC's ten-year totals for Taylor County went from 21 tests (2005 to 2014) to 32 (2008 to 2017), the share going from 14.3% to 28.1%.

EPA's 1993 zone map puts Taylor County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Next door, the shares run from 19.0% in Monongalia County to 36.9% in Preston County, with Monongalia County below Taylor County.

Taylor County, Geology

The ground under Taylor County

Predicted

USGS's geologic map puts all of Taylor County's mapped land in one class: moderate radon potential. The map puts 83.2% of Taylor County in the area it calls Central Allegheny Plateau and 16.8% in Eastern Allegheny Plateau and Mtns. USGS gives both a radon index of 10, in the moderate band (9 to 11).
