The Environmental Protection Agency (EPA) is an independent agency of the United States 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.
Water pollution is the contamination of water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
The Saint Louis River is a river in the U.S. states of Minnesota and Wisconsin that flows into Lake Superior. The largest U.S. river to flow into the lake, it is 192 miles (309 km) in length and starts 13 miles (21 km) east of Hoyt Lakes, Minnesota. The river's watershed covers 3,634 square miles (9,410 km2). Near the Twin Ports of Duluth, Minnesota and Superior, Wisconsin, the river becomes a freshwater estuary.
Environmental racism, ecological racism, or ecological apartheid is a form of racism leading to negative environmental outcomes such as landfills, incinerators, and hazardous waste disposal disproportionately impacting communities of color, violating substantive equality. Internationally, it is also associated with extractivism, which places the environmental burdens of mining, oil extraction, and industrial agriculture upon indigenous peoples and poorer nations largely inhabited by people of color.
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states from South East geopolitical zone.
The Pine Bend Refinery is the largest oil refinery in Minnesota, located in the Twin Cities suburbs of Rosemount and Inver Grove Heights next to southern split of U.S. Highway 52 and Minnesota State Highway 55. The refinery is notable for being the largest in the United States to be located in a state without any oil wells. Overall, it ranked 14th in the country as of 2012 by production, with a nameplate capacity of 320,000 barrels (51,000 m3) per day. The facility is owned by Flint Hills Resources (FHR), a subsidiary of Koch Industries.
The Upper Mississippi River is the portion of the Mississippi River upstream of St. Louis, Missouri, United States, at the confluence of its main tributary, the Missouri River. Historically, it may refer to the area above the Arkansas Post, above the confluence of Ohio River, or above Cape Girardeau.
The Niger Delta Development Commission (NDDC) is a federal government agency established by former Nigerian president Olusegun Obasanjo in the year 2000, with the sole mandate of developing the oil-rich Niger Delta region of Nigeria. In September 2008, President Umaru Yar'Adua announced the formation of a Niger Delta Ministry, with the Niger Delta Development Commission to become a parastatal under the ministry. One of the core mandates of the commission is to train and educate the youths of the oil rich Niger Delta regions to curb hostilities and militancy, while developing key infrastructure to promote economic diversification and productivity.
The New York State Department of Environmental Conservation is a department of New York state government. The department guides and regulates the conservation, improvement, and protection of New York's natural resources; manages Forest Preserve lands in the Adirondack and Catskill parks, state forest lands, and wildlife management areas; regulates sport fishing, hunting and trapping; and enforces the state's environmental laws and regulations. Its regulations are compiled in Title 6 of the New York Codes, Rules and Regulations. It was founded in 1970, replacing the Conservation Department, and is headed by Basil Seggos.
An index of biological integrity (IBI), also called an index of biotic integrity, is a scientific tool typically used to identify and classify water pollution problems, although there have been some efforts to apply the idea to terrestrial environments. An IBI associates anthropogenic influences on a water body with biological activity in the water body, and is formulated using data developed from biosurveys. Biological integrity is associated with how "pristine" an environment is and its function relative to the potential or original state of an ecosystem before human alterations were imposed. Biological integrity is built on the assumption that a decline in the values of an ecosystem's functions are primarily caused by human activity or alterations. The more an environment and its original processes are altered, then by definition, the less biological integrity it holds for the community as a whole. If these processes were to change over time naturally, without human influence, the integrity of the ecosystem would remain intact. Similar to the concept of ecosystem health, the integrity of the ecosystem relies heavily on the processes that occur within it because those determine which organisms can inhabit an area and the complexities of their interactions. Deciding which of the many possible states or conditions of an ecosystem is appropriate or desirable is a political or policy decision.
This timeline of the history of environmentalism is a listing of events that have shaped humanity's perspective on the environment. This timeline includes human induced disasters, environmentalists that have had a positive influence, and environmental legislation.
The Deepwater Horizon oil spill was an environmental disaster which began on 20 April 2010, off the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at 4.9 MMbbl. After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history.
Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies. Extensive industrialization and rapid urban growth exacerbated water pollution as a lack of regulation allowed for discharges of sewage, toxic chemicals, nutrients and other pollutants into surface water.
Oil spill governance in the United States is governed by federal law.
The 70-acre Burlington Northern is a former railroad tie treatment plant by Burlington Northern Railroad in northern Minnesota, USA. The unlined creosote and fuel oil lagoons, which had been used to treat the ties contaminated groundwater. In 1985, the site was listed as a United States Environmental Protection Agency (EPA) Superfund. Contaminated soils were excavated and capped and a groundwater gradient pump -out well is in place.
In 1962 and 1963, industrial accidents spilled 3.5 million gallons of oil into the Mississippi and Minnesota Rivers. The oil covered the Mississippi River from St. Paul to Lake Pepin, creating an ecological disaster and a demand to control water pollution.
The Line 3 pipeline is an oil pipeline owned by the Canadian multinational Enbridge. Operating since 1968, it runs 1,031 miles (1,659 km) from Hardisty, Alberta, Canada to Superior, Wisconsin, United States.
The Line 3 oil spill was a 1.7 million gallon crude oil spill in Minnesota on March 3, 1991. The Line 3 pipeline, then owned by the Lakehead Pipeline Company, ruptured on a wetland near Grand Rapids, Minnesota, spilling oil into the Prairie River, a tributary of the Mississippi River. It was the largest inland oil spill in the history of the United States.
