United States Environmental Protection Agency in the context of "Particulate"

Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th president of the United States, serving from 1969 until his resignation in 1974. A member of the Republican Party, he represented California in both houses of the United States Congress before serving as the 36th vice president under President Dwight D. Eisenhower from 1953 to 1961. His presidency saw the reduction of U.S. involvement in the Vietnam War, détente with the Soviet Union and China, the Apollo 11 Moon landing, and the establishment of the Environmental Protection Agency and Occupational Safety and Health Administration. Nixon's second term ended early when he became the only U.S. president to resign from office, as a result of the Watergate scandal.

Nixon was born into a poor family of Quakers in Yorba Linda, Southern California. He graduated from Whittier College with a Bachelor of Arts in 1934 and from Duke University School of Law with a Juris Doctor in 1937, practiced law in California, and then moved with his wife Pat to Washington, D.C., in 1942 to work for the federal government. After serving in the Naval Reserve during World War II, he was elected to the House of Representatives in 1946. His work on the Alger Hiss case established his reputation as a leading anti-communist. In 1950, he was elected to the Senate. Nixon was the running mate of Eisenhower, the Republican Party's presidential nominee in the 1952 and 1956 elections. Nixon served for eight years as vice president, and his two terms saw an increase in the notability of the office. He narrowly lost the 1960 presidential election to John F. Kennedy. After his loss in the 1962 race for governor of California, Nixon announced his retirement from politics. However, he ran again for the presidency in 1968 and defeated the Democratic candidate, Vice President Hubert Humphrey.

Silent Spring is an environmental science book by Rachel Carson. Published on September 27, 1962, the book documented the environmental harm caused by the indiscriminate use of DDT, a pesticide used by soldiers during World War II. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.

In the late 1950s, Carson began to work on environmental conservation, especially environmental problems that she believed were caused by synthetic pesticides. The result of her research was Silent Spring, which brought environmental concerns to the American public. The book was met with fierce opposition by chemical companies, but it swayed public opinion and led to a reversal in US pesticide policy, a nationwide ban on DDT for agricultural uses, and an environmental movement that led to the creation of the US Environmental Protection Agency.

Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognised and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by up to ten times from one set of standards to another. Many countries specify standards to be applied in their own country. In Europe, this includes the European Drinking Water Directive and in the United States, the United States Environmental Protection Agency (EPA) establishes standards as required by the Safe Drinking Water Act. China adopted its own drinking water standard GB3838-2002 (Type II) enacted by Ministry of Environmental Protection in 2002. For countries without a legislative or administrative framework for such standards, the World Health Organization (WHO) publishes guidelines on the standards that should be achieved.

Where drinking water quality standards do exist, most are expressed as guidelines or targets rather than requirements, and very few water standards have any legal basis or, are subject to enforcement. Two exceptions are the European Drinking Water Directive and the Safe Drinking Water Act in the United States, which require legal compliance with specific standards. In Europe, this includes a requirement for member states to enact appropriate local legislation to mandate the directive in each country. Routine inspection and, where required, enforcement is enacted by means of penalties imposed by the European Commission on non-compliant nations.

The Mid-Atlantic is a region of the United States located in the eastern part of the country. Traditional definitions include seven U.S. states: New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, West Virginia, and the national capital of Washington, D.C.

Depending on various factors, different regional divisions exist however: the U.S. Bureau of Labor Statistics in its newest regional division excludes New York from the region; the U.S. Census Bureau excludes Delaware, Maryland, Virginia and West Virginia from the region; USGS defines the region by watersheds thus additionally including North Carolina; the EPA excludes both New York and New Jersey; the U.S. Maritime Administration excludes upper New Jersey and New York; the Office of Small Business Programs of the U.S. Department of Defense excludes New York. When discussing climate, Connecticut is sometimes included, since its climate is closer to the Mid-Atlantic than the rest of the New England region.

Traditional ecological knowledge (TEK) is a cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with their environment.

The application of TEK in the field of ecological management and science is still controversial, as methods of acquiring and collecting knowledge—although often including forms of empirical research and experimentation— may differ from those most often used to create and validate scientific ecological knowledge. Non-tribal government agencies, such as the U.S. EPA, have established integration programs with some tribal governments in order to incorporate TEK in environmental plans and climate change tracking. In contrast to the universality towards which contemporary academic pursuits often aim, TEK is not necessarily a universal concept among various societies, instead referring to a system of knowledge traditions or practices that are heavily dependent on "place".
