Oregon State Sanitary Authority
The Oregon State Sanitary Authority (OSSA) was the first agency in the U.S. state of Oregon that was charged with protecting the environment. In 1938, Oregon voters, by a three-to-one margin, approved an initiative to regulate water pollution and to create an enforcement agency under the jurisdiction of the Oregon State Board of Health. Political pressure that led to the initiative had begun as early as the 1920s, when the Board of Health, the U.S. Public Health Service, the Izaak Walton League, and others had expressed concerns about water pollution and its threats to human health. Pollution had caused many fish kills on the Willamette River in the 1920s, and Portland, on the lower river, had often closed its part of the Willamette to swimming because of sewage in the water. Since many of the biggest polluters were along the Willamette, OSSA focused its efforts there. Raw domestic sewage from cities and wastes from pulp mills, paper mills, and other industrial sites produced the gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Department Of Environmental Quality

Sulfite Process
The sulfite process produces wood pulp that is almost pure cellulose fibers by treating wood chips with solutions of sulfite and bisulfite ions. These chemicals cleave the bonds between the cellulose and lignin components of the lignocellulose. A variety of sulfite/bisulfite salts are used, including sodium (Na+), calcium (Ca2+), potassium (K+), magnesium (Mg2+), and ammonium (NH4+). The lignin is converted to lignosulfonates, which are soluble and can be separated from the cellulose fibers. For the production of cellulose, the sulfite process competes with the Kraft process which produces stronger fibers and is less environmentally costly. History The use of wood to make pulp for paper began with the development of mechanical pulping in the 1840s by Charles Fenerty in Nova ScotiaBurger, Peter 'Charles Fenerty and his Paper Invention''.

Environment Of Oregon
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape Mendocino i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Management Authorities In The United States
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers a ...

Oregon Legislative Assembly
The Oregon Legislative Assembly is the state legislature for the U.S. state of Oregon. The Legislative Assembly is bicameral, consisting of an upper and lower house: the Senate, whose 30 members are elected to serve four-year terms; and the House of Representatives, with 60 members elected to two-year terms. There are no term limits for either house in the Legislative Assembly. Each Senate district is composed of exactly two House districts: Senate District 1 contains House Districts 1 and 2, SD 2 contains HD 3 and HD 4, and so on. (Maps of Senate districts can be found in the Oregon State Senate article.) Senate districts contain about 127,700 people, and are redrawn every ten years. The legislature is termed as a "citizens' assembly" (meaning that most legislators have other jobs.) Since 1885, its regular sessions of up to 160 days occurred in odd-numbered years, beginning on the second Monday in January. Effective 2012, the legislature moved into an annual session, with ...

Tom McCall
Thomas Lawson McCall (March 22, 1913 January 8, 1983) was an American statesman, politician and journalist in the state of Oregon. A Republican, he was the state's thirtieth governor from 1967 to 1975. A native of Massachusetts, McCall grew up there and in central Oregon and attended the University of Oregon in Eugene. After college, he worked as a journalist, including time at ''The Oregonian'' in Portland during Later he worked in radio and then in television as a newscaster and political commentator. He made an unsuccessful bid for Congress in 1954, losing in the general election to Edith Green. While working for TV station KGW, he produced a documentary on pollution in Oregon, which helped to spur environmental cleanup of the air and the Willamette River. In 1964, McCall won his first political office, Oregon Secretary of State, followed by two terms as governor, where he worked towards environmental cleanup, the bottle bill, and public ownership of beaches on the coast amon ...

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Sewage Treatment
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incor ...

Paper Mill
A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers. History Historical investigations into the origin of the paper mill are complicated by differing definitions and loose terminology from modern authors: Many modern scholars use the term to refer indiscriminately to all kinds of mills, whether powered by humans, by animals or by water. Their propensity to refer to any ancient paper manufacturing center as a "mill", without further specifying its exact power source, has increased the difficulty of identifying the particularly efficient and historically important water-powered type. Human and animal-powered mills The use of human and animal powered mills was known to Muslim and Chinese paperma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulp Mill
A pulp mill is a manufacturing facility that converts wood chips or other plant fiber sources into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods ( kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements. Wood and other plant materials used to make pulp contain three main components (apart from water): cellulose fibres (desired for papermaking), lignin (a three-dimensional polymer that binds the cellulose fibres together) and hemicelluloses, (shorter branched carbohydrate polymers). The aim of pulping is to break down the bulk structure of the fiber source, be it chips, stems or other plant parts, into the constituent fibers. Chemical pulping achieves this by degrading the lignin and hemicellulose into small, water-soluble molecules that can be washed away from the cellulose fibers with ...
