History Of Rockford, Michigan
Rockford is a city in Kent County in the U.S. state of Michigan. The population was 5,719 at the 2010 census. Located along the Rogue River, the city is part of the Grand Rapids metropolitan area and is about north of the city of Grand Rapids. History The area was first settled by Marlin Hunter, who settled along the Rogue River in 1842. By 1845, several other families arrived and settled the community under the name Laphamville, and the community received a post office under that name. The community was platted in 1865 and incorporated as a village in 1866. At that time, the community's name changed to Rockford. The community was originally based around the lumber industry but was soon supported by a shoe factory and tannery at the turn of the century. The village incorporated as a city in 1935. Wolverine World Wide has major operations in the city for over 100 years. In modern times, its former tannery site used Scotchgard chemicals to waterproof shoes, which cont ...

City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

2010 United States Census
The United States census of 2010 was the twenty-third United States national census. National Census Day, the reference day used for the census, was April 1, 2010. The census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 census. This was the first census in which all states recorded a population of over half a million people as well as the first in which all 100 largest cities recorded populations of over 200,000. Introduction As required by the United States Constitution, the U.S. census has been conducted every 10 years since 1790. The 2000 U.S. census was the previous census completed. Participation in the U.S. census is required by law of persons living in the United States in Title 13 of the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Rapids Christian Schools
Grand Rapids Christian Schools is a Christian private school system in Kent County, Michigan, serving grades K-12. Most of its campuses are in Grand Rapids while one is in Rockford. Its administrative headquarters are in Grand Rapids. Tom DeJonge is the superintendent of the system. History Circa 2004 the school had a debt of about $20 million, and in 2009 the debt was down to $12.5 million; the school had incurred debt partly due to renovations of the Millbrook school and the construction of the Rockford school. That year Richard DeVos and Helen DeVos gave a donation of $10 million, and the debt was reduced to $2.5 million.

Indian Trails
Indian Trails, Inc. is an inter-city bus company based in Owosso, Michigan, with offices in Romulus (in Metro Detroit) and Kalamazoo. History Indian Trails was founded in 1910 in Owosso as the Phillips-Taylor Livery Service, whose main business was transporting cargo to and from Durand Union Station and the surrounding Shiawassee County. Beginning in the 1910s, the company expanded to include intercity offerings, becoming known as the Owosso-Flint Bus Line. and by the 1930s served much of southern Michigan. Many of its buses ran along US 12, known as "the Old Indian Trail." Reflecting this, in 1935, the company took its current name, Indian Trails.

White Pine Trail State Park
Fred Meijer White Pine Trail State Park is a long linear state park in the U.S. state of Michigan. The trail extends from northern Grand Rapids to Cadillac, and it lies on the path graded for the Grand Rapids and Indiana Railroad (later absorbed by the Pennsylvania Railroad). The White Pine Trail is a rail trail park. It was named the "Fred Meijer White Pine Trail State Park" after a donation by grocery store executive Fred Meijer. History As the railroad ceased operation in the mid-1980s, the Michigan Department of Transportation came to own the rail bed. By 1994 the property was transferred to the Michigan Department of Natural Resources (DNR), which began replacing the rails with a trail for public recreational use. Current Condition The trail extends from Ann Street in Grand Rapids north to Cadillac. The trail has only one unpaved section: one extending between Howard City and Big Rapids.

Perfluorooctanesulfonic Acid
Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group and thus a perfluorosulfonic acid. It is an anthropogenic (man-made) fluorosurfactant, now regarded as a global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and related stain repellents. The acronym "PFOS" refers to the parent sulfonic acid and to various salts of perfluorooctanesulfonate. These are all colorless or white, water soluble solids. Although of low acute toxicity, PFOS has attracted much attention for its pervasiveness and environmental impact. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. History In 1949, 3M began producing PFOS-based compounds by electrochemical fluorination resulting in the synthetic precursor perfluorooctanesulfonyl fluoride. In 1968, organofluorine content was detected in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perfluorooctanoic Acid
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8 carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock. PFOA is considered a surfactant, or fluorosurfactant, due to its chemical structure, which consists of a perfluorinated, ''n''-octyl "tail group" and a carboxylate "head group". The head group can be described as hydrophilic while the fluorocarbon tail is both hydrophobic and lipophobic. The tail group is inert and does not interact strongly with polar or non-polar chemical moieties; the head group is reactive and interacts strongly with polar groups, specifically water. The "tail" is hydrophobic due to being non-polar and lipophobic because fluorocarbons are less susceptible to the London dispersion force than hydrocarbons. PFOA is one of many synthetic organofluorine compounds collectively known as per- and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotchgard
Scotchgard is a 3M brand of products, a stain and durable water repellent applied to fabric, furniture, and carpets to protect them from stains. Scotchgard products typically rely on organofluorine chemicals as the main active ingredient along with petroleum distillate solvents. Development of the formula The original formula for Scotchgard was discovered accidentally in 1952 by 3M chemists Patsy Sherman and Samuel Smith. Sales began in 1956, and in 1973 the two chemists received a patent for the formula. 3M reformulated Scotchgard and since June 2003 has replaced PFOS with perfluorobutanesulfonic acid (PFBS). PFBS has a much shorter half-life in people than PFOS (a little over one month vs. 5.4 years). 3M now states that Scotchgard utilizes a proprietary fluorinated urethane. Environmental concerns During 1999, the United States Environmental Protection Agency (EPA) began an investigation into the class of chemicals used in Scotchgard, after receiving information on the ...

Plat
In the United States, a plat ( or ) (plan) is a cadastral map, drawn to scale, showing the divisions of a piece of land. United States General Land Office surveyors drafted township plats of Public Lands Surveys to show the distance and bearing between section corners, sometimes including topographic or vegetation information. City, town or village plats show subdivisions broken into blocks with streets and alleys. Further refinement often splits blocks into individual lots, usually for the purpose of selling the described lots; this has become known as subdivision. After the filing of a plat, legal descriptions can refer to block and lot-numbers rather than portions of sections. In order for plats to become legally valid, a local governing body, such as a public works department, urban planning commission, or zoning board must normally review and approve them. In gardening history, in both varieties of English (and in French etc), a "plat" means a section of a formal par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
