Pollution of water is very common. Water is divided into surface water and groundwater with separate guidelines for each. Each state has its own Department of Environmental Quality that operates under the Environmental Protection Agency (EPA). The rules are more stringent for surface water because of fish and other water life. However, if it is surface water, the EPA will get involved. Each state has some type of "discharge permit" or "aquifer protection permi.t" Unfortunately, these permits do not prohibit industrial waste entering public groundwater, they specify the levels that any industry, including mining, can pollute water. The Federal EPA has mandated levels for any metal or chemical that has been shown to be carcionogenic. These metals and their "allowed levels" are posted on the EPA Website for Safewater.
There are three sources of pollants of water:
1) Unlined tailing imoundment.
2) Current water quality: Pollutant Levels for pH, sulfate, hardness, Total Dissolved Solids, heavy metals, radioactive materials, and nitrates of surrounding water.
3) Composition of Tailings Impoundments that are polluting the water
