Toxicity of Metals in Water and Sediment to Aquatic Biota By John M. Besser and Kenneth J. Leib Chapter E19 of Integrated Investigations of Environmental Effects of Historical Mining in the Animas River Watershed, San Juan County, Colorado Edited by Stanley E. Church, Paul von Guerard, and Susan E. Finger Professional Paper 1651
In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which can create ...
Ground water entering the pit is pumped up into the moat. As a quarry becomes deeper, water inflows generally increase and it also becomes more expensive to lift the water higher during removal; this can become the limiting factor in quarry depth. Some water-filled quarries are worked from beneath the water, by dredging.

Exposure to potentially harmful levels usually occurs through drinking of contaminated water (due to zinc water pipes or accidental industrial releases). Effects include nausea and stomach cramps.
What are the environmental effects of zinc in water? Zinc was not attributed a water hazard class, because it is not considered a hazard. This however only concerns elementary zinc. Some zinc compounds, such as zinc arsenate and zinc cyanide, may be extremely hazardous. Zinc is a dietary mineral for humans and animals.
Jan 21, 2015· Zinc is one of the most common elements in the earth's crust. Zinc is found in the air, soil, and water and is present in all foods.
