Acid mine drainage

Problems with acid mine drainage from many abandoned mines are known throughout Colorado. The leaking mine water that goes into Cement Creek was stem by the EPA team at the Gold King Mine when the accident occurred. The EPA safe crew was supposed to be cleaning up the abandoned mine but they accidentally sent 3 millions of gallon of chemicals filled waste water pour into the river. To be more specific, a concrete bulkhead was built to plug the leak by the EPA team. They are planning to add pipes

the number of fractures per unit length, area or volume. Fracture density is largely dependent on local bedding thickness and location relative to local faults. Due to the mountainous nature of the Andes Mountains and the close proximity of Ocelot Mine to the MFTB, the limestone host rock can be considered to have a heavy fracture density. Fractures also have a strong influence on the permeability of a host rock. Permeability is a function of the transmissivity of individual rock fractures as well

mining has the potential and has been known to affect the quality of surrounding surface water and groundwater. In response to environmental concerns and government regulations, the mining industry worldwide increasingly monitors water discharged from mine sites and has implemented a number of management strategies to prevent water pollution. One such strategy is the use of remote sensing to assess impact of mining activities on land and water resources. Environmental impact assessment is now an integral

than one seams extending over big vertical durations. Coal mining in all likelihood consequences in an extra disturbance to the geologic conditions of an area than any other form of mining(Ehlen, Haneberg & Larson, 2005, p. 79). The two ways to mine coal; surface mining and underground mining both extraction operations have their own personal negative impact on the environment. Strip mining a type of surface mining, is highly destructive scraping away at earths landscape to reach the coal buried

Recommendations After evaluation, more should be done to restore the water quality in the Animas river. The Gold King Mine site along with other nearby mines should become a superfund site. This would result in environmental assessments, testing technologies, and implementing them for effective site remediation. Specifically, the EPA should plug the adits. This will prevent more acid mine drainage from reaching Cement Creek. There are many remediation methods that can be used to clean up the metals including

With both mines worked for Pb and Zn, naturally, these two elements are found amongst the key metals of contamination and toxicity to organics found on the site. Lead is released into the wider environment in the form of elemental Pb, oxides and hydroxides along with oxyanion complexes. Normally, it occurs with an oxidation state of 0 or +II. Pb(II) is more common than its uncharged counterpart and more reactive. It forms mononuclear and polynuclear oxides and hydroxides (Smith et al., 1995). Low

riots, strikes, and civil incursions that would eventually attract the attention of the United Mine Workers of America (UMWA). The UMWA was started in Ohio in the late 1800s, but moved into West Virginia in the early 20th century. There were many influential figures within the organization, most notably John L. Lewis. Lewis was president

surprisingly defeat Exxon’s mine proposal and preserve the way of life for one of the smallest and poorest bands of Native Americans in the United States. This tribe is known as Sokaogon Chippewa of Mole Lake and with the help of those with similar intentions battled for nearly thirty years to defeat Exxon. With the proposal defeated, one thing was certain, the Sokaogon Chippewa would continue to harvest wild rice without fears of it being contaminated. Yet with no mine, the area has suffered from

A characteristic feature of our time is the intensification and globalization of human impact on the surrounding natural environment, which is accompanied by unprecedented intensification and globalization of the negative consequences of this impact. The problem of pollution of the natural environment becomes so acute as because of the growth in the volume of industrial and agricultural production, and about the qualitative change in production under the influence of scientific and technological

Diamonds are one of the most popular minerals in the world and yet people are not aware of the circumstances it takes to acquire this such unique mineral. Many people would agree when I say that this mineral is such a nice thing to look at, but few people actually know what it is made of and how it was formed. These precious minerals are composed of Carbon. The process to making this immaculate mineral is as following. First, you must bury Carbon dioxide deep into the earth; approximately, 100
