What these figures count
Only 4 tests were reported to CDC for Baca 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: 2005 to 2022 (every CDC figure on file).
Baca County, Compared
Baca County radon figures, compared
Calculated by Radon411More than half: 61.8% of the 34 radon tests reported to CDC for Baca County over the 2005 to 2014 laboratory totals read at least 4 pCi/L. That places it 11th of 47 Colorado counties with 30 or more tests for the same period. That is 12.3 points above the 49.5% pooled from 63 Colorado counties.
The newest figure, in 2022, counts only 4 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 34-test figure.
The median result, 4.5 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 20.0 pCi/L. The rest split 11.8% under 2 pCi/L and 26.5% from 2 to 4 (Colorado: 29.2% and 21.4%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 61.8% share point the same way here.
2 of its 3 bordering counties with figures ran higher, led by Las Animas County at 63.2%; Prowers County reported 28.5%. Statewide for the same period, Pueblo County reported the highest share (69.9%) and Prowers County the lowest (28.5%).
The busiest year on file was 2021, with 20 tests reported; the quietest, 2017, had 1.
Nationally, every county with a figure for the same period pools to 36.0%; Baca County sits 25.8 points above it.

Tests behind these figures
54 tests
- CDPHE says these data do not give actual radon levels in homes that have not been tested.
- When possible, only tests conducted before a mitigation system was installed are used.
- Some counties have very small numbers of test results, and their summaries may be less representative.
- These figures describe tests reported to Colorado CDPHE in this area. They count a different set of tests than CDC's figures and are not a reading of any one home.
Measured: Colorado CDPHE data, 2005-2025.

The ground under Baca County
PredictedMost of the ground under Baca County is one class on USGS's geologic map: 97.8% of its land is high radon potential, with 2.2% moderate. The map puts 86.0% of Baca County in the area it calls Ogallala Formation and 11.7% in High Plains, with one smaller area beside them. USGS gives both a radon index of 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Ogallala Formation | Tertiary sandstone, in part covered by windblown eolian sand and loess deposits. | High | 12 | 86.0% |
| High Plains | Quaternary deposits and Cretaceous marine shales that locally have a high radiometric signature. | High | 12 | 11.7% |
| Cimmaron River Valley | Tertiary and Quaternary sandstone, siltstone, shale, and alluvium overlain by eolian sand and loess. | Moderate | 10 | 2.2% |
