Martin County Coal Slurry Spill
The Martin County coal slurry spill was a mining accident that occurred after midnight on October 11, 2000, when the bottom of a coal slurry impoundment owned by Massey Energy in Martin County, Kentucky, broke into an abandoned underground mine below. The slurry came out of the mine openings, sending an estimated of slurry down two tributaries of the Tug Fork River. By morning, Wolf Creek was oozing with the black waste; on Coldwater Fork, a stream became a expanse of thick slurry. The spill, which contained arsenic and mercury, killed everything in the water. It was over five feet deep in places and covered nearby residents' yards. The spill polluted hundreds of miles () of the Big Sandy River and its tributaries and the Ohio River. The water supply for over 27,000 residents was contaminated, and all aquatic life in Coldwater Fork and Wolf Creek was killed. The spill was 30 times larger than the Exxon Valdez oil spill, spilling . It was one of the worst environmental disast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Of Kentucky Highlighting Martin County
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring t ...

Presidency Of George W
A presidency is an administration or the executive, the collective administrative and governmental entity that exists around an office of president of a state or nation. Although often the executive branch of government, and often personified by a single elected person who holds the office of "president", in practice, the presidency includes a much larger collective of people, such as chiefs of staff, advisers and other bureaucrats. Although often led by a single person, presidencies can also be of a collective nature, such as the presidency of the European Union is held on a rotating basis by the various national governments of the member states. Alternatively, the term presidency can also be applied to the governing authority of some churches, and may even refer to the holder of a non-governmental office of president in a corporation, business, charity, university, etc. or the institutional arrangement around them. For example, "the presidency of the Red Cross refused to support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mining Disasters In Kentucky
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dam Failures In The United States
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, tap water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Tailings Dam Failures
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin County Kentucky Water Crisis
The Martin County water crisis is an on-going public health crisis that began in 2000, when a coal slurry spill contaminated the area’s water supply with cancer-causing disinfection byproducts and coliform bacteria. Residents report the water having a strong smell of chlorine, discoloration, odd taste, sediment and irritation/burning when in contact with skin. The contamination was caused by the spillage of approximately 300 million gallons of arsenic and mercury concentrated coal sludge into an abandoned underground mine and two tributaries of the Tug Fork River by local coal company Massey Energy on October 11 of 2000. According to the Environmental Protection Agency (EPA) The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it be ..., the spill was one of the worst environmental disasters e ...

Mountaintop Removal Mining
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. This process is considered to be safer compared to underground mining because the coal seams are accessed from above instead of underground. In the United States, this method of coal mining is conducted in the Appalachian Mountains in the eastern United States. Explosives are used to remove up to 400 vertical feet (120 m) of mountain to expose underlying coal seams. Excess rock and soil is dumped into nearby valleys, in what are called "holler fills" ("hollow fills") or "valley fills".U.S. Environmental Protection Agency, "Mountaintop Mining/Valley Fills in Appalachia: Final Programmatic Environmental Impact Statement," issued 2005 June 25, available ahttp://www.epa.gov/region03/mtntop/index.htm(accessed 2006 August 20).

Sludge (film)
''Sludge'' is a 2005 documentary film by Appalshop filmmaker Robert Salyer chronicling the Martin County Sludge Spill that was an accident that occurred after midnight on October 11, 2000 when a coal sludge impoundment in Martin County, Kentucky, broke through an underground mine below, propelling 306 million gallons of sludge down two tributaries of the Tug Fork River. The movie documents the continuing story of the Martin County disaster, the resulting federal investigation, and the looming threat of coal sludge ponds throughout the coalfield region. In the United States today, coal is the largest single source of fuel for energy production. Annually, the country mines over a billion tons of coal. Coal waste is a consequence of this consumption; the Mine Safety and Health Administration The Mine Safety and Health Administration (MSHA) () is a large agency of the United States Department of Labor which administers the provisions of the Federal Mine Safety and Health Act of 19 ...

Robert Salyer
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Appalshop
Appalshop is a media, arts, and education center located in Whitesburg, Kentucky, in the heart of the southern Appalachian region of the United States. History Appalshop was founded in 1969 as the Appalachian Film Workshop, a project of the United States government's War on Poverty. The organization was one of ten Community Film Workshops started by a partnership between the federal Office of Economic Opportunity and the American Film Institute. In 1974 the worker-operated organization evolved into a nonprofit company called Appalshop and established itself as a hub of filmmaking in Appalachia, and since that time has produced more than one hundred films, covering such subjects as coal mining, the environment, traditional culture, and the economy. The name was officially changed to reflect changing business structure and goals. Appalshop also produces theater, music, and spoken-word recordings (released on its June Appal Recordings label), as well as photography, multimedia, ...

Administrative Leave
Administrative leave is a temporary leave from a job assignment, with pay and benefits intact. Generally, the term is reserved for employees of non-business institutions such as schools, police, and hospitals. The definition of administrative leave may vary by institution. Individuals may also be eligible for administrative leave for various reasons including: bereavement, jury/court appearances, military leave, internal reviews, and investigations. In academic settings, administrative leaves are provided for the same purpose as research/study leaves, i.e., to allow individuals to improve themselves academically and to engage in research to foster their effectiveness as teachers and scholars. An employee may be placed on administrative leave when an allegation of misconduct is made against an employee, either by a co-worker, student, parent, an alleged victim, or a police officer. During the leave, employers may investigate the situation before determining an appropriate course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
