What is the location of the uranium in the aquifer?
The uranium is contained in the uppermost sands of the Laramie-Fox Hills formation, which is a marginal marine sandstone horizon of Cretaceous age. Some drinking water is produced from this horizon, but wells are located at a considerable distance from the uranium ore, where the water quality is not conducive for human consumption. The depth varies from 80 – 600 feet below the surface, depending on the thickness of the over-lying strata. The uranium ore body and aquifer already naturally have heavy metals and salts present, the foremost of which is uranium.
