The ground under Jasper County
PredictedUSGS's geologic map puts all of Jasper County's mapped land in one class: low radon potential. The map puts 72.9% of Jasper County in the area it calls Jackson Prairies and 14.7% in Pine Hills, with one smaller area beside them. USGS gives the first a radon index of 8 and the second 6, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Jackson Prairies | Sand, marl, clay, and limestone. | Low | 8 | 72.9% |
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 14.7% |
| North Central Hills/Flatwoods | Tertiary nonmarine to deltaic sediments ranging from sand to clay. | Low | 8 | 12.4% |

Jasper County beside the ground around it
Across Mississippi 0.1% of the land is rated high; none of Jasper County's is. None of the 7 counties that border it has any moderate-potential ground either.
