Kingston Fossil Plant Coal Fly Ash Slurry Spill
The Kingston Fossil Plant coal fly ash slurry spill was an environmental and industrial disaster that occurred on Monday December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, used a series of ponds to store and dewater the fly ash, a byproduct of coal combustion. The spill released a slurry of fly ash and water, which traveled across the Emory River and its Swan Pond embayment, onto the opposite shore, covering up to of the surrounding land. The spill damaged multiple homes and flowed into nearby waterways including the Emory River and Clinch River, both tributaries of the Tennessee River. It was the largest industrial spill in United States history. The initial spill, which resulted in millions of dollars worth of property damages and rendered many propertie ...

Dewatering
Dewatering is the removal of water from a location. This may be done by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes. Construction dewatering, unwatering, or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson, or mine shaft, by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible "dewatering" pumps, centrifugal ("trash") pumps, eductors, or application of vacuum to well points. The international business research company Visiongain valued the global dewatering pump market at $6.4 billion in 2018. Processes Deep wells A deep well typically consists of ...

Melton Hill Dam
Melton Hill Dam is a hydroelectric dam on the Clinch River just south of Oak Ridge, Tennessee, United States. The dam is operated by the Tennessee Valley Authority, which built the dam in the early 1960s to extend the Tennessee Valley's continuous navigation channel up the Clinch as far as Clinton and to increase TVA's overall power-generating capacity. The dam impounds the Melton Hill Lake, and is the only TVA tributary dam serviced by a navigation lock. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017. Melton Hill Dam was named for a knob atop nearby Copper Ridge where the U.S. Coast and Geodetic Survey installed a triangulation station in 1884.Tennessee Valley Authority, ''The Melton Hill Project: A Report on the Planning, Design, Construction, Initial Operations, and Costs'', Technical Report No. 15 (Knoxville, Tenn.: Tennessee Valley Authority, 1966), pp. 1-19, 27-31, 53, 108-109.

Fort Loudoun Dam
Fort Loudoun Dam is a hydroelectric dam on the Tennessee River in Loudon County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in the early 1940s as part of a unified plan to provide electricity and flood control in the Tennessee Valley and create a continuous navigable river channel from Knoxville, Tennessee to Paducah, Kentucky. It is the uppermost of nine TVA dams on the Tennessee River. The dam impounds the Fort Loudoun Lake and its tailwaters are part of Watts Bar Lake. The generating capacity of Fort Loudoun Dam is enhanced by the Tellico Reservoir, from which water is diverted via canal to Fort Loudoun Lake. It and associated infrastructure were listed on the National Register of Historic Places in 2017. Fort Loudoun Dam is named after Fort Loudoun, an 18th-century British colonial fort built during the French and Indian War. The fort— which was located about south of the dam site†...

Watts Bar Lake
Watts Bar Lake is a reservoir on the Tennessee River created by Watts Bar Dam as part of the Tennessee Valley Authority system. Geography Located in the U.S. state of Tennessee about midway between the cities of Chattanooga and Knoxville, the lake begins as the Tennessee River below Fort Loudoun Dam () in Lenoir City, Tennessee and stretches 72.4 miles (116.5 km) to Watts Bar Dam (), near Spring City, Tennessee. The Clinch River connects to the main channel of the lake at mile 568 () near Southwest Point (site of Andrew Jackson and John Sevier's 1803 confrontation) in Kingston, Tennessee. The widening of the Clinch by the lake makes that river navigable all the way up to Melton Hill Dam (), which is equipped with a navigation lock allowing navigation upstream through Oak Ridge and Clinton. The partially navigable Emory River connects with the Clinch near the TVA's Kingston Steam Plant just upriver from the meeting with the Tennessee. Including the Clinch and ...

Watts Bar Dam
Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States. The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river. The dam is the technical boundary between the Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga. Watts Bar Dam is named for Watt Island, a sandbar located at the dam site prior to the dam's construction.Tennessee Valley Authority, ''The Watts Bar Project: A Comprehensive Report on the Planning, Design, Construction, and Initial Operations of the Watts Bar Project'', Technical Report No. 9 (Washington, D.C.: U.S. Government Printing Office, 1949), 1-11, 39-47.

Leukemia
Leukemia ( also spelled leukaemia and pronounced ) is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. These blood cells are not fully developed and are called ''blasts'' or ''leukemia cells''. Symptoms may include bleeding and bruising, bone pain, fatigue, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy. The exact cause of leukemia is unknown. A combination of genetic factors and environmental (non-inherited) factors are believed to play a role. Risk factors include smoking, ionizing radiation, petrochemicals (such as benzene), prior chemotherapy, and Down syndrome. People with a family history of leukemia are also at higher risk. There are four main types of leukemia— acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic ...

Lung Cancer
Lung cancer, also known as lung carcinoma (since about 98–99% of all lung cancers are carcinomas), is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. Lung carcinomas derive from transformed, malignant cells that originate as epithelial cells, or from tissues composed of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are generated by the malignant transformation of connective tissues (i.e. nerve, fat, muscle, bone), which arise from mesenchymal cells. Lymphomas and melanomas (from lymphoid and melanocyte cell lineages) can also rarely result in lung cancer. In time, this uncontrolled growth can metastasize (spreading beyond the lung) either by direct extension, by entering the lymphatic circulation, or via hematogenous, bloodborne spread – into nearby tissue or other, more distant parts of the body. Most cancers that originate from within the lungs, known as primary lung cancers, are carcinomas. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain Cancer
A brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness. The cause of most brain tumors is unknown. Uncommon risk factors include exposure to vinyl chloride, Epstein–Barr virus, ionizing radiation, and inherited syndromes such as neurofibromatosis, tuberous sclerosis, and von Hippel-Lindau Disease.

Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. Additionally, its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where the river also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, ''Tanasi'', which was located on the Tennessee side of the Appalachian Mountains. Course The Tennessee River is formed at the confluence of the Holston and French Broad rivers in present-day Knoxville, Tennessee. From Knoxville, it flows southwest through East Tennessee into Chattanooga before crossing into Alabama. It travels through the Huntsville and Decatur area befor ...
