Radon tests reported for Parmer County, 2008 to 2017, laboratory
CDC holds 1 reported test for Parmer County over the 2008 to 2017 laboratory totals, a result of 10.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Parmer County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Parmer 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).
Parmer County, Compared
Parmer County radon figures, compared
Calculated by Radon411CDC's largest figure for Parmer County rests on 1 test over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 10.6 pCi/L, with a middle value of 10.6 pCi/L.
The nearest counties with a figure are Randall County (59 miles away) at 71.4%, Potter County (78 miles away) at 20.0% and Lubbock County (84 miles away) at 57.8%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
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 Parmer County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Parmer County, Geology
The ground under Parmer County
PredictedUSGS's geologic map puts all of Parmer County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Northern High Plains and Plateaus, to which USGS gives a radon index of 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Northern High Plains and Plateaus | Tertiary sandstone, siltstone, shale. | Moderate | 10 | 99.8% |

Parmer County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Parmer County's is. Of the 5 counties that border it, none has as large a share of moderate-potential ground; Castro County comes nearest at 100%.
