West Feliciana Parish, Geology
USGS's geologic map puts all of West Feliciana Parish's mapped land in one class: low radon potential. The map puts 54.0% of West Feliciana Parish in the area it calls Floodplain and 31.9% in Terraces, with one smaller area beside them. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).

|---|---|---|---|---|
| Floodplain | Alluvium, marsh, silt, and clay. | Low | 7 | 54.0% |
| Terraces | Clays, siltstone, and sandstone. | Low | 8 | 31.9% |
| Loess Hills | Loess. | Low | 7 | 14.1% |
