SUB-PROBLEMS INCLUDING LEADING TO IMPAIRMENT AND BEST PRACTICES FOR POTENTIAL SOURCES OF WATER CONTAMINATION
Some of the factors leading to impairment and their associated Best Practices are discussed in this chapter.
Acid Mine Drainage
Acidic drainage from mines is caused by sulfide minerals which have been exposed to air or water and then seep into groundwater or surface water. The acidic materials are harmful to aquatic ecosystems and humans through direct contact and ingestion of water. There are an estimated 500,000 abandoned mines in the United States with 130 of them either on the National Priorities List or capable of being on it. This contamination covers more than 1 million acres of land. Surface water and groundwater is contaminated from seepage from various mine openings, waste rock, mill t ailings, waste slurries, and waste sludges which have been placed in unlined lagoons.
Best Practices for Acid Mine Drainage (See endnote 5)
The use of water can be limited by the presence of scum, foam, and unnatural water color and taste. Trash including plastics, litter, debris, and other solid wastes from people also cause degradation.
