The ground under Pearl River County
PredictedUSGS's geologic map puts all of Pearl River County's mapped land in one class: low radon potential. The map puts 88.2% of Pearl River County in the area it calls Pine Hills and 11.4% in Coastal Pine Meadows. USGS gives both a radon index of 6, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 88.2% |
| Coastal Pine Meadows | Alluvial deltas consisting of gravel, sand and clay. | Low | 6 | 11.4% |
