Acid washed out of mines frequently finds its way into the water table, altering the ph of nearby streams and rivers and threatening the survival of wildlife. If a tailings reservoir bursts, it can result in a toxic mudslide that can block the flow of waterways and wipe out any living thing it encounters. The berkeley pit is a former open pit copper mine located in butte, montana, united states. It is 1 mi (1,600 m) long by 1 2 mi (800 m) wide with an approximate depth of 1,780 feet (540 m). It is filled to a depth of about 900 feet (270 m) with water that is heavily acidic (2. 5 ph level), about the acidity of coca-cola, lemon juice, or gastric acid. Water seeping and flowing from the mines, in turn, contaminated local streams, springs, and groundwater resources. Huge piles of crushed rock, called tailings, left on the surface after mining also contributed to the contamination because water leached lead , zinc , and cadmium out of the tailings. The environmental challenges from coal mining include coal mine accidents, land subsidence, damage to the water environment, mining waste disposal and air pollution. These are either environmental pollution or landscape change. A conceptual framework for solving mine environmental issues is proposed. Mining water refers to water that has been used from a designated mine water source, in order to complete mining functions. In southeast ohio, a new grassroots organization has emerged to resist a proposed, more than 500-acre strip mine on public lands. Friends of perry state forest is sounding the alarm about ecological and economic threats presented by the proposed mine, and mobilizing turnout for a public meeting before the ohio department of natural resources on february 26 in new lexington. There is an increased risk of chemical contamination of ground water when minerals in upturned earth seep into the water table, and watersheds are destroyed when disfigured land loses the water it once held. Strip mining causes dust and noise pollution when top soil is disrupted with heavy machinery and coal dust is created in mines. Contamination of water material is often excavated during strip mining and the solvents used for this extraction leaks into the drinking water in the area where the strip mining is taking place. It is also impossible to conduct strip mining without releasing a great deal of toxins and pollutants into the surrounding atmosphere, which also leads to increased water contamination. 1882 x link between cholera and contaminated water discovered. 1884 x kentucky department of mines and minerals established to ensure proper. The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that.
