Under normal conditions, there is very little uranium in the groundwater; it’s stuck to the sand grains in the rocks

ISL mining causes uranium to be freed from the rocks, contaminating the groundwater

This diagram shows how the uranium-bearing gchannels are stacked on top of each other;

this makesthis makes containment of mining fluids during operations

and restoration of contaminated groundwater after mining gdifficult.
