Pecos County radon figures, compared
Calculated by Radon411CDC's county radon counts over the 2007 to 2016 laboratory totals cover 140 Texas counties, and Pecos County is not among them: no year's figure and no ten-year laboratory total names it. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
The nearest counties with a figure are Midland County (85 miles away) at 1.0%, Lubbock County (202 miles away) at 57.8% and El Paso County (219 miles away) at 0.0%. Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%).
EPA's 1993 map puts Pecos County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 62% of the county's land low radon potential.

Pecos County, Geology
The ground under Pecos County
PredictedUSGS's geologic map splits Pecos County: 62.2% of its land is low radon potential and 37.8% moderate. The map puts 62.2% of Pecos County in the area it calls Southern High Plains and Plateaus and 37.8% in Western Mountains and Basins. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Southern High Plains and Plateaus | Paleozoic and Mesozoic sandstone, limestone, shale. | Low | 7 | 62.2% |
| Western Mountains and Basins | Precambrian igneous rocks, silicic volcanic rocks, and alluvium. | Moderate | 9 | 37.8% |
