Radon tests reported for Faulkner County, 2008 to 2017, laboratory
CDC holds 19 reported tests for Faulkner County over the 2008 to 2017 laboratory totals, with a median of 1.3 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Faulkner County beside the counties around it is how this page reads it.
What these figures count
Only 19 tests were reported to CDC for Faulkner 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).
Faulkner County, Compared
Faulkner County radon figures, compared
Calculated by Radon411CDC's largest figure for Faulkner County rests on 19 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 5.3 points and no rank or comparison is drawn from it. Results reached as high as 8.6 pCi/L, with a middle value of 1.3 pCi/L.
Pulaski County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 6.8% of its tests at or above 4 pCi/L. Farther out, Saline County (40 miles away) at 31.9%, Garland County (61 miles away) at 45.8% and Washington County (121 miles away) at 14.3% have figures too. 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 Faulkner 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.

The ground under Faulkner County
PredictedUSGS's geologic map puts all of Faulkner County's mapped land in one class: low radon potential. The map puts 55.3% of Faulkner County in the area it calls Arkansas Valley and 44.7% in Athens Plateau/Fourche Mountains. USGS gives both a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Arkansas Valley | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 55.3% |
| Athens Plateau/Fourche Mountains | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 44.7% |
