Acid mine drainage

history. In order to protect and conserve the environment along lake Superior in Minnesota, and keep local residents safe, the PolyMet mining project should be stopped. I will firstly discuss what “sulfide mining” really is, and what the impacts of a mine this size would be for both the environment and the people of Minnesota. Then I will shed light on the business PolyMet, and what they would have to do in order for the project to succeed and be safe. An article written by MPR news hosts Elizabeth

Mining is notoriously known for acid mine draining; the pollutant that occurs when water flows through a sulfur-exposed material. Not only is treatment for acid mine drainage expensive, causing taxpayers millions of dollars to clean it; it also contaminates drinking water, kills wildlife, and destroys infrastructure. The Telkwa Coal Mine in Smithers, British Columbia, is especially known for its role in damaging one of the town’s biggest industries; fishing. The coal mine is located near the Skeena River;

aspects of water quality such as guidelines for water quality, water quality parameters, contaminants that effect water quality, water quality tests and catchment area influences. Samples from the Dee River, from above and below the former Mount Morgan mine site, will be tested and compared in terms of pH level, conductivity and water hardness. The links that exist between pH levels and water hardness will also be investigated. These three variables have dramatic influences on the water quality of the

problem. Coal ash possesses unique chemical properties that allow for the remediation of other environmental concerns, such as the treatment of soil polluted with heavy metals, the removal of nutrients from wastewater, and the remediation of acid mine drainage in streams. Coal ash is known to contain a number of different toxic metals, the exact content dependent upon the coal it is formed from. Containing this potential pollution hazard is an expensive problem, as approximately 75% of all ash generated

AMD Remediation at Shoup’s Run Watershed Alanna O’Neil Introduction: The main pollutant of surface water in the mid-Atlantic region is Acid Mine Drainage, AMD, also called Abandoned Mine Drainage. AMD is a nonpoint source pollution that has degraded more than 4,500 stream miles, in just the mid-Atlantic region, due to the drainage of metal-rich water from mining activities (Jacobs). The runoff is extremely acidic due to the exposure of pyrite containing rocks, a sulfur bearing mineral (FeS2), during

Dear Friends at the Gold King Superfund Site: We would like to thank you for giving this project to our company. We understand how serious this acid mine drainage problem is and would like to assure you confidence in our ability to safely deal with the issue. Our company has been in the business of water treatment and acid mine drainage cleanup for 40 years now. We have dealt with 203 similar issues since the creation of our company. Although we are based in Pennsylvania, we do water treatment projects

Natural Resources Gogebic Taconite Mine Report Introduction The Wisconsin Department of Natural Resources is an agency of the great state of Wisconsin. The WDNR’s purpose is to protect, maintain, and preserve the resources of Wisconsin. We--as representatives of the WDNR--feel that the mine may not be the best way to uphold our prime directive. The negative effect that the mine will have on the environment far outway the positive effect. The creation of this mine will impact the watershed, the flora

presented by the EPA in regards to the Gold King Mine spill accident. In the next section, there will be further elaboration of the case study and its related components to the decision-making framework. Case Study: The Gold King Mine Spill Gold King Mine Spill Background In order to answer the research question of how do stakeholder responses to mining accidents impact water politics, this paper will look at a case study involving the Gold King Mine spill. The case study of the Gold King

systems are in various stages of age ranging from youth to maturity. There are also man made drainage systems to allow water to flow from areas where rivers haven't formed down to the water's edge. With Howe Sound being a U shaped valley, this area is prone to rockslides and landslides. In this photo, you can see steel pipes coming out from under the road. These were installed as a form of drainage underneath the sea to sky highway to prevent damage to the road and flooding. In this photo

produces CO2, a gas that is linked to global warming through the greenhouse effect. The combustion of coal produces gaseous emissions of sulphur dioxide (SO2) and nitrous oxides (NOx) that are responsible for the production of ‘acid rain’ and ‘ground level ozone’. Acid rain occurs when SO2 and NOx gases react in the atmosphere with water, oxygen and other chemicals to form acidic compounds. Ground level ozone (O3) is mainly responsible for smog that forms a brown haze over cities. Ground level
