Iron Mining Wash Contamination
Mining And Water Pollution Safe Drinking Water Foundation
Dec 17, 2016 Heavy Metal Contamination Leaching. Heavy metal pollution is caused when such metals as arsenic, cobalt, copper, cadmium, lead, silver and zinc contained in excavated rock or exposed in an underground mine come in contact with water. Metals are leached out and carried downstream as water washes over the rock surface.
