Small amounts of elements can be separated from mining wastes through the movement of groundwater. as a result, these elements may end up in drinking water and cause diseases.

which process is involved in the pollution of groundwater by mining wastes in this case?

The minerals and the elements are taken away from the site area towards the residential area by the water i.e flood water or rain water. Open-pit mining involves the cleaning of the different mineral materials and rocks in order to extract the valuable products. But, the sedimentation process is done after the rocks or other minerals are eroded by the process of erosion, This process leads to a small particles of minerals and rocks on the surface of the land. Making it easy to reach the residential areas through the help of rain water and floods.

If the minerals and parts of sediments are harmful to the living beings health, then it will  cause further damage to the life, as it will produce disorders in there bodies.
