Radon tests reported for Edwards County, 2022
| Year | Share of reported tests at or above 4 pCi/L |
|---|---|

2022: 30.0%. Across these years the share ran from 0.0% to 30.0%. Each column counts radon tests reported to CDC that year, not homes.
What these figures count
Only 10 tests were reported to CDC for Edwards County over 2022, 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: 2022. Measured data period: 2016 to 2022 (every CDC figure on file).
Edwards County, Compared
Edwards County radon figures, compared
Calculated by Radon411CDC's largest figure for Edwards County rests on 10 tests in 2022, 3 of them at or above 4 pCi/L, so each test moves its share by 10.0 points and no rank or comparison is drawn from it. Results reached as high as 11.4 pCi/L, with a middle value of 2.4 pCi/L.
Of the counties bordering it, 2 have a figure in 2019: Pawnee County reported the largest share at or above 4 pCi/L, 66.7%, and Ford County the smallest, 42.4%. Farther out, Barton County (51 miles away) at 24.6%, Reno County (67 miles away) at 20.8% and Rice County (68 miles away) at 55.9% have figures too. Pooled across 102 Kansas counties, 33.7% of reported tests reached that level; across every county in the country with a figure, 29.0%.
Statewide for the same period, Jewell County reported the highest share (71.9%) and Reno County the lowest (20.8%). EPA's 1993 map puts Edwards County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 82% of the county's land moderate radon potential.

The ground under Edwards County
PredictedMost of the ground under Edwards County is one class on USGS's geologic map: 82.0% of its land is moderate radon potential, with 18.0% high. The map puts 82.0% of Edwards County in the area it calls Arkansas River Lowlands and 18.0% in Ogallala Formation. USGS gives the first a radon index of 10, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Arkansas River Lowlands | Dune sands and alluvium. | Moderate | 10 | 82.0% |
| Ogallala Formation | Tertiary sandstone, in part covered by windblown eolian sand and loess deposits. | High | 12 | 18.0% |
