According to Wikipedia the definition of water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and ground water). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. # During the 18th and 19th centuries it was believed that water could dilute any substance and people would use the rivers and lakes as dumping ground for waste. Without thinking about contamination and their downstream neighbors animal carcasses, industrial effluent and raw sewage were often dumped into waterways. The main ways that pollutants enter the Great Lakes region are point source pollution, non point source pollution and atmospheric pollution. Point source pollution is when pollutants enter through a specific point such as a drainage pipe. This can be traced back to a specific owner and point. Non point source pollution such as sediment from construction sites and eroding shorelines; fertilizer and pesticides from homeowners and farms; human and animal waste; and oil, grease and salt from highways are harder to trace to a specific owner or entry point. This is usually when rain or snowmelt move over the land which picks up pollutants and dumps them into water bodies. Atmospheric pollution is when the pollution falls form the sky and is another form of non point pollution. Waste incinerators and coal burning energy plants are a major cause of atmospheric pollution. Waste from hospitals and burning of fossil fuels produces large amounts of mercury in the air. This happens as the pollution moves through the air and is deposited by rain or snow such as acid rain. Lake Huron is 850 cubic miles or water, has 3,827 miles of lakeshore, it is 206 miles across, 183 miles north to south and has an average depth of 195 feet. Lake Huron’s 23,000 square…...

Lake Huron

...Great Lakes are the world’s largest freshwater system (TEACH). Including Lake Erie, Michigan, Huron, Superior, and Ontario, the five lakes are an important source of fresh water and are home to many species of wildlife. However, with the belief that water could dilute any substance, the lakes also became a destination of dumping grounds for many different types of pollutants. Ranging from point source pollution such as industrial waste from drainage pipes to non-point source pollution like pesticide and fertilizer runoff from farms, these pollutants and others have had adverse effects on the lakes. Such adverse effects include reducing the water quality, contaminating soils, and damaging the lake ecosystems. This damage produces harmful repercussions on the fish and wildlife stocks, and to the humans surrounding the Great Lakes region as well. To observe this, we will analyze the tissue concentrations in lake trout of four influential pollutants in Lake Huron, to see if there is a correlation to the total biomass of the lake trout. BACKGROUND Sources of Pollution in the Great Lakes Point-source pollution refers to a direct source of pollution, such as a pipe or other vessel. Early industries like pulp and paper companies located in the Great Lakes region believed that anything could be dissolved in water, and thus neutralized. As a result, many wastes (such as mercury) were dumped into the Great Lakes. There have also been observations of fecal matter pollution from......

Cause and Effect on Pollution in Lake Huron

...Water quality has become a major issue along the southern shores of Lake Huron in recent years. The sources of this pollution are many, and the culprits as equally diverse. Nonpoint-source pollution is another term for polluted runoff. Water washing over the land, whether from precipitation, car washing or watering crops or lawns, picks up an array of contaminants including oil, sand and salt from roadways, agricultural chemicals, and nutrients and toxic materials from both urban and rural areas. The term nonpoint is used to distinguish this type of pollution from point source pollution, which comes from specific sources such as sewage treatment plants or industrial facilities. •Pathogens Pathogens are disease causing microorganisms, such as bacteria and viruses that come from the fecal waste of animals and humans. Pathogens wash off the land from wild animal, farm animal and pet waste, and can also enter the lake from improperly functioning septic systems, leaky sewer lines and boat sanitary disposal systems. •Nutrients Nutrients are compounds that stimulate plant growth, like nitrogen and phosphorous. In high concentrations, they can become both an environmental and health threat. Nutrients in polluted waters can come from agricultural fertilizers, septic systems, home lawn care products, and yard and animal wastes. •Toxic Contaminants Toxins are substances that can harm aquatic and human life. They are created by a wide variety of human practices and......

...Cause and Effects of Water Pollution in Lake Huron Litiecha A. Lee English Composition/115 Saturday, November 17, 12 Jeanette Trammell Cause and Effect of Water Pollution in Lake Huron The North American great lakes including Lake Erie, Michigan, Huron, Superior, and Ontario, are the largest fresh water supply and home to many of the world’s wildlife. Lake Huron is the third largest of the lakes by volume of water. It average depth is 59 meters and it has a maximum depth of 750 feet. The following paragraphs will outline a major cause of pollution in found in Lake Huron, a secondary cause, two contributing causes, its effect on humans, and the effect pollution found in Lake Huron has on the economy. The pollution in Lake Huron has a negative effect on the vegetation, wildlife and humans. Sources of pollution in the lake are diverse, over the years pollutant sources were separated into two categories, point source and non-point source. The point source of pollution in Lake Huron was due to an earlier belief that water can melt and neutralize waste and chemicals. Because of this belief, in the early nineteenth century and part of the early twentieth century sewage was released directly into the lake waters during a storm to avoid sewage overload. According to Shear, H. (2006), “Both sewage and other organic wastes cause the water quality to decline and bacteria growth to increase.” Today the process has changed or is in the process of changing,......

Water Pollution Cause and Effect Essay

...Water Pollution Cause And Effect Essay Water pollution is a global plague that affects the people, animals, and plants. These life forms need water to survive. The causes are contributed greatly by the human population. Recently, laws have been passed to protect the precious drinking waters. Although they are in effect, most are ignored or loop holes have been found by major corporations so the can still "legally" dump harmful waste near water supplies. There are several factors that causes water pollution. One of the reasons that the water pollution problem is so severe is that it is not actually illegal to dump pollutants into water bodies. Sewage, sludge, garbage, and even toxic pollutants are all dumped into the water. Often, governments either do not care or simply look the other way. Across the world, about half of all sewage is dumped into water bodies in its original form. No efforts are made to disinfect the sewage or to remove especially harmful pollutants. Even if sewage is treated, problems still arise. Treated sewage forms sludge, which is sent out into the sea and dumped. Many cities and countries dump sewage out at sea. Often, they place it not far from their own coastline, often killing all the sea wildlife in the dumping area. In addition to sewage, chemicals dumped by industries and governments are another major source of water pollution. Raymond Furon could not believe his finds when he tested a river used by a reservation as a main source of water...

Pollution in Lake Huron

...Thesis Statement Lake Huron is the third largest of the Great Lakes by volume containing 850 cubic miles of water and it measures 206 miles from east to west and 183 miles north to south. In addition, Lake Huron has 3,827 miles of coastline (Human Health and the Great Lakes n.d.). Lake Huron, much like most lakes, contains a large variety of fish and wildlife and there is always the chance of pollution occurring in lakes due to illegal dumping and waste disposal, discharge of pollutants from vessels on the lake, human waste sewage, and faulty infrastructure which can accidently cause pollution. However pollution may occur, it is harmful to not only the ecology and the fish and wildlife in the area but also to humans who reside near the lake. According to a University of Michigan (U of M) report, Pollution’s Effects on the Great Lakes Ecosystems, over 20% of the world’s fresh water supply is in the Great Lakes region (U of M, n.d.) and with the world water reserves diminishing, it is essential to protect the integrity of the water to the maximum extent possible. Major Causes of Pollution in Lake Huron While there are many factors which contribute to the pollution of Lake Huron, the main source sources of pollution which cause the most damage is direct dumping of hazardous and toxic materials in the lake such as industrial waste, discharges from ships on the lake and also raw human sewage which is dumped in the lake. According to the Lake Huron Center for Coastal......

Lake Huron and the

...wellbeing of animals, humans, and the environment that our society had clean water not only in and around areas of Lake Huron but for the world as a whole. “About 70 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers.” (How much water is there on, in, and above the Earth?, 2013) The impact of polluted water can affect many different sources that can greatly impact our society in a negative way. “The effects of water pollution are varied. They include poisonous drinking water, poisonous food animals (due to these organisms having bio accumulated toxins from the environment over their life spans), unbalanced river and lake ecosystems that can no longer support full biological diversity, deforestation from acid rain, and many other effects. These effects are, of course, specific to the various contaminants.” (Rubin) In order to help prevent the negatives effects happening in Lake Heron, the public must be informed and governmental agencies need to create more action in improving this matter. Figure 1: (http://www.mnr.gov.on.ca/en/Business/GreatLakes/2ColumnSubPage/STEL02_173901.html) Lake Heron, located between Michigan and Canada, is the third largest bodies of water in the world and covers at least 23,000 square miles.

...Hillary Ogutu Honors Environmental Mr. Sup October 3, 20113 Water Pollution All around the world countries are fighting to keep their water clean.  Whether it’s streams, rivers, lakes, or the oceans, countries have taken greater measures to maintain a high quality of water for both human consumption and as a key component to the environment. We deal with the pollution problems and then decide on ways to clean it up. This valuable resource is the key to survival; both plants and animals depend on water for their growth so it must be kept clean. The major contributors to water pollution can be classified into two categories, industrial and agricultural.             What is water pollution? “It is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks uses or lives in it. “ Water covers up 70% of the Earth’s surface and makes up over 60% of the human body. Water pollution affects marine, ecosystems, wildlife health and human well being. Some of the major contributors that lead to water pollution come from industrial and agricultural.             Industry is the highest source of pollution in the United States, causing for more than half of the volume of all the water pollution and also for the most deadly pollutants.  Many of the industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. The industrial contains pollutants like asbestos, phosphates,......

Lake Huron

...Water Pollution is a very big deal in The Great Lakes. Lake Huron is the third biggest lake of the The Great Lakes and it is being polluted everyday. The people around Lake Huron are also being affected by the pollution. The three main causes of the pollution is nonpoint source pollution, point source pollution and Air Pollution. Non-point Source pollution is pollution that does not come from specific locations. The water quality has become a major issue along the southern shores of Lake Huron in recent years. The major types of pollutant carried by run-offs are pathogens, nutrients and toxic contaminants. Pathogens are bacterias that come from the fiscal waste of animals and humans. It also comes from leaky sewer lines and boat sanitary disposal systems. Nutrients are compounds that stimulate plant growth, like nitrogen and phosphorus. In high concentrations, it can become a threat to the environment and to humans health. Nutrients in polluted waters can also come from agricultural fertilizers, septic systems, home lawn care and yard and animal wastes. The toxic contaminants are created by a variety of human practices and products like heavy metals, pesticides, and organic compounds like PCB’s. PCBs are Polychlorinated Biphenyls which is a group of manufactured organic chemicals that contains 209 individual chlorinated chemicals. Oil, grease, gasoline from roadways, and chemicals used in homes, gardens, yards and on farm crops are major sources of the toxic......

Cartoon commenting on polluted condition of the Thames. Punch, 10 July 1858. Source: Wikimedia Commons • The growth of the major industrial cities also caused water pollution. All too often, rivers that pass through urban areas became a receptacle for human waste products, both domestic and industrial. Sewage, as in most cities, was washed out into the streets where it found its way to the rivers with disastrous consequences. • In the first half of the 18th century, both London and Paris, the largest cities in Europe with respectively 1 and 2.4 million inhabitants by 1850, experienced a series of recurring epidemics of cholera and typhoid. In 1832 over 20,000 Parisians died in a cholera outbreak; London experienced similar outbreaks. This was caused by increasing amounts of sewage dumped into the Seine and Thames rivers. • London was one of the first cities in the world to build a sewer system and improve the quality of its drinking water supply. The London Board of Health eliminated cesspools in the late 1840s, and a Metropolis Water Act of 1852 forced water companies to move their intakes upstream and regulate......

The Effects of Water Pollution on the Economy

...The Effects of Water Pollution on the Economy Terri Cunningham ECO 405 Dr. Page July 25, 2014 Every human has five basic needs in order to survive: food, water, air, shelter, and warmth. Of these five needs, three are in grave danger from the effects of pollution. The water and air supply are being contaminated on a daily basis, and as a direct result, spreading to the food supply. A variety of pollutants from a number of sources are constantly being introduced into the environment, with most people none the wiser. Most of the population is aware of, or can extrapolate the negative effects environmental pollution can have on a person, plant, or animal’s physical health, but many don’t realize the major impact that pollution can have on a country’s economic health. With the global population increasing every moment, the demand for food resources rises right along with it, putting a strain on the planet’s water resources. As farmers scramble to produce more crops to meet the growing demand, they inadvertently add more harmful contaminates to the water supply. According to a Bloomberg article, the Organization for Economic Cooperation and Development said that this surge in agricultural production and water pollution costs billions of dollars in developed countries like the United States, France, and Spain, and is ready to surpass that mark in China and India (Patel, 2012). The chemical pesticides and fertilizers widely used in agricultural farming leech......

Determining the Causes and Effects of Water Pollution in Lake Huron

...Causes and Effects of Water Pollution in Lake Huron The Great Lakes, Lake Erie, Michigan, Huron, Superior, and Ontario, are our largest freshwater system. Lake Huron, like the other Great Lakes contain many species of wildlife, and is in danger of being polluted. This pollution is harmful to fish, wildlife stocks, and to the humans of this region. At the University of Mississippi, Latham, A., Wright, E., & Tsang, A. [n.d.] produced a study that focused specifically on Pollution's Effects on the Great Lakes Ecosystem. Determining the causes and effects of water pollution in Lake Huron may facilitate new ideas and solutions for cleaning up our waterways’ and improving public health. Although there are many causes of Lake Huron’s pollution, most fall under three categories: 1) Point-source pollution; 2) Nonpoint-source pollution; and 3) Air pollution. Point-source pollution refers to mercury, fecal matter, and sewage, from treatment plants or industrial facilities, being dumped into the Lake. Nonpoint-source pollution refers to runoff of polluted water from crops or lawns which contain contaminants. These contaminants may be oil, sand, salt from roadways, agricultural chemicals, and nutrients and toxic materials from urban or rural areas (The Lake Huron Centre for Coastal Conservation, 1998-2012). Additionally, air pollution is also a major concern. According to the Lake Huron Centre for Coastal Conservation, “…the air quality of the Ontario Lake Huron......

...Eng115 Cause and effect draft | Cause And Effect Of Water Pollution In Lake Huron | Assignment 3.1 Determining Cause and Effects | Keimara Brooks | | 8/19/2012 | Dr.Gordon | Introduction The Great Lakes together form the world’s largest fresh water system. They supply a significant amount of the world’s fresh water supply. The great lakes are not only an important source of fresh water, these mast bodies of water also are known to be a home for many wildlife species. For many years the Great Lakes have served as a dumping ground for many harmful pollutants. From industrial waste and drain pipes to pesticides and fertilizer runoff s the Great Lakes are suffering. Damage of this kind produce harmful conditions for the fish, wildlife, and humans dwelling in the surrounding area of the region. Sources of Pollution in the Great Lakes Earlier age industrial companies, such as pulp and paper, operating near the Great Lakes region dumped waste including mercury into the water using pipes and/or vessels. Some of this polluting was done involuntarily with the malfunctioning of these pipes or vessels. Other times were intentional sticking to the theory that water “neutralizes” all substances. Fecal matter was another strand of pollution found in later experiments performed on the water of the Great Lakes. The source of this pollutant was believed to be......
