Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 1959
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

List Of Power Stations In Tennessee
The U.S. state of Tennessee receives its power from a variety of sources. The Tennessee Valley Authority (TVA) is the primary utility in Tennessee which generates electricity and sells it to hundreds of local utilities and industrial customers. Like most of the US, the sources used to generate power in Tennessee have changed substantially in the last decade. Coal's share of power has declined from nearly 60% in 2008 to about 25% in 2018, while natural gas has increased significantly. Tennessee is home to the two newest nuclear reactors in the US at Watts Bar Nuclear Plant, unit 2 being the first to begin operation in the 21st century. After Watts Bar Unit 2 began operation in late 2016, nuclear power passed coal as the top source of electricity. In November 2018 natural gas produced more power than coal for the first time in Tennessee. Tennessee is home to the third largest pumped-storage hydroelectric facility in the US, and has the third highest net generation of hydroelectric pow ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Combustion Residuals
Coal combustion products (CCPs), also called coal combustion wastes (CCWs) or coal combustion residuals (CCRs), are categorized in four groups, each based on physical and chemical forms derived from coal combustion methods and emission controls: *Fly ash is captured after coal combustion by filters ( bag houses), electrostatic precipitators and other air pollution control devices. It comprises 60 percent of all coal combustion waste (labeled here as coal combustion products).It is most commonly used as a high-performance substitute for Portland cement or as clinker for Portland cement production. Cements blended with fly ash are becoming more common. Building material applications range from grouts and masonry products to cellular concrete and roofing tiles. Many asphaltic concrete pavements contain fly ash. Geotechnical applications include soil stabilization, road base, structural fill, embankments and mine reclamation. Fly ash also serves as filler in wood and plastic products, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Environmental Protection Agency
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 began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tr ...

Allen Combined Cycle Plant
The Allen Combined Cycle Plant is a 1.1-gigawatt (1,100 MW) natural gas power plant located south of Memphis, Tennessee that began generating electricity in 2018. It is operated by Tennessee Valley Authority (TVA). Background TVA announced plans that the Allen Fossil Plant would be replaced with a $975 million natural gas plant in order to reduce emissions by 2018 set by a 2011 agreement with the Environmental Protection Agency (EPA). The TVA had plans to utilize greywater from the nearby Maxson Wastewater Treatment Plant, but was determined to be unviable and expensive. Instead, the TVA drilled wells on the Memphis Sand Aquifer to use for the plant's cooling source. During subsequent testing of groundwater and alluvial aquifer in the vicinity of the combined cycle plant, TVA discovered that water contained arsenic and lead which raised concerns that use of the on-site wells may lead to cross-contamination of the Memphis Sand aquifer. As a result, the use of wells on site was susp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
