Stewart County, Geology
The ground under Stewart County
PredictedUSGS's geologic map puts all of Stewart County's mapped land in one class: low radon potential. All of it lies in the area the map calls Coastal Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Cretaceous and Tertiary marine and coastal sediments including limestone, sandstone, sand, silt, and clay. Coastal plan sands containing glauconite may generate locally elevated radon. | Low | 8 | 100% |
