Chicago Lake Tunnel
The Chicago Lake Tunnel was the first of several tunnels built from the city of Chicago's shore on Lake Michigan two miles out into the lake to access unpolluted fresh water far from the city's sewage. Waterborne disease in early Chicago In the early decades of its existence, the growing city was only about three feet above the surface of Lake Michigan, and the areas of early European settlement were flat and sandy with a high water table. European settlers in Chicago only needed to dig 6 to 12 feet to create a private well. The same settlers, however, would also dig privy vaults for human waste nearby. Because the sandy soil topped a layer of hard clay, human waste would sink from the outhouse, meet the impervious clay, and travel laterally into the freshwater supply. As a result, Chicago suffered numerous widespread outbreaks of waterborne diseases. The Chicago Board of Health was organized in 1835, in response to the threat of a cholera epidemic, and later outbreaks of cholera i ...

Lake Michigan
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume () and the third-largest by surface area (), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide, deep, Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake. Lake Michigan is the world's largest lake by area in one country. Located in the United States, it is shared, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan. Ports along its shores include Milwaukee and the City of Green Bay in Wisconsin; Chicago in Illinois; Gary in Indiana; and Muskegon in Michigan. Green Bay is a large bay in its northwest, and Grand Traverse Bay is in the northeast. The word "Michigan" is believed to come from the Ojibwe word (''michi-gami'' or ''mishigami'') meaning "great water". History Some of most studie ...

Privy Digging
Privy digging is the process of locating and investigating the contents of defunct outhouse vaults. The purpose of privy digging is the salvage of antique bottles and everyday household artifacts from the past. Privy digging is a form of historical digging and is often conducted on private residential properties. Construction sites and major developments around older areas of towns and cities are also likely places to look for evidence of privies. Historical contractors (privy diggers who dare to enter into contracts enabling them to investigate vaults on commercial or industrial properties) are also engaging in privy digging. Privies are also called pits, holes, and chambers. In some locations, like New York City, vaults are sometimes referred to as “wells”, due to their appearance and often considerable depth. In these instances well digging is synonymous with privy digging. Academic controversies There are controversies regarding who should be permitted to investigate pri ...

Waterborne Diseases
Waterborne diseases are conditions (meaning adverse effects on human health, such as death, disability, illness or disorders) caused by pathogenic micro-organisms that are transmitted in water. These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. They are a pressing issue in rural areas amongst developing countries all over the world. While diarrhea and vomiting are the most commonly reported symptoms of waterborne illness, other symptoms can include skin, ear, respiratory, or eye problems. Lack of clean water supply, sanitation and hygiene (WASH) are major causes for the spread of waterborne diseases in a community. Therefore, reliable access to clean drinking water and sanitation is the main method to prevent waterborne diseases. Microorganisms causing diseases that characteristically are waterborne prominently include protozoa and bacteria, many of which are intestinal parasites, or invade the tissues or circ ...

Cholera
Cholera is an infection of the small intestine by some strains of the bacterium '' Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure. Cholera is caused by a number of types of ''Vibrio cholerae'', with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked shellfish is a common source. Humans are the only known host for the bacteria. Risk factors for the disease include poor sanitation, not enou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archai ...

Water Cribs In Chicago
The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the City of Chicago with drinking water from Lake Michigan. Water is collected and transported through tunnels located close to beneath the lake, varying in shape from circular to oval, and ranging in diameter from . The tunnels lead from the water cribs to Pumping Stations located onshore, then to water purification plants Jardine Water Purification Plant (the world's largest) and the Sawyer Water Purification Plant (operating since 1947), where the water is then treated before being pumped to all parts of the city as well as 118 suburbs. The city has had nine permanent cribs of which six are still standing and two are in active use. Current and former water cribs Two-Mile Crib The Two-Mile Crib was constructed as part of a scheme by Ellis S. Chesbrough in 1865, to help with the purification of the water because of damage caused by the city dumping sewage into the la ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in ...
