Cause and Effects of Water Pollution Essay

Water Quality is very much in the news these days and it is also a suppuration public concern. Water is one of the most important resources on the planet and affects nearly every aspect of life. The Great Lakes pissingshed contains a large persona of the worlds fresh surface water. The Lakes support the water needs, and jobs of millions of people and poor water quality is an increasing frustration.DescriptionLake Huron is the second largest of the Great Lakes and the 5th largest in the world, with the most irregular shape of any of the Great Lakes. Even its largest island, Manitoulin, is wider than the State of Rhode Island, and has five small lakes of its own. The lake is connected with its neighbor, nearly same-sized L. Michigan, only by a narrow straight called the Straights of Mackinac, which is spanned by an 8 km-long bridge, the Mighty Mac. (International Lake Environment Committee) Water pollution is defined as a change in the chemical, physical and biological health of a waterway due to human activity. Unfortunately, this definition applies to the waters of Lake Huron and has had a negative feign on the people who use and rely on this body of water. (Study mode 04, 2012) Although there are many causes of Lake Hurons pollution, most fall under(a) 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, and salt from roadways, agricultural chemicals, and solid foods and toxicant materials from urban or rural areas (The Lake Huron Centre for Coastal Conservation, 1998-2012). There are many different causes for the pollution in Lake Huron. Some pollutants institute include chemicals and metals, nutrient enrichment, pathogens and bacteria, and calefaction.

The urban areas are constructed with a lot of water-repellent materials used to lay roads and build houses. With impermeable materials covering most of the ground, there is no place for rainwater water to sink in. All the rain water, along with all the chemicals it washes away, runs off in a gutter system. This in turn f pocket-sizes into a stream or the lake itself. This type of runoff includes chemicals, fertilizers, pesticides and suspended solids. (Cause and Effect of the Pollution of Lake Huron.

The effects of water pollution can range from aquatic deformities to contaminated fish to dead lakes.

Sources of nutrients include municipal wastewater treatment plants, septic systems, and agricultural runoff. Areas of Lake Huron where pathogens are of concern are Saginaw Bay, Severn Sound, and the southeastern shore of the Lake Huron Basin. Effects of pathogens in these regions have included localized beach closings due to E. coli contamination. (Human Health and the Great Lakes April 29, 2003)Chemical contaminationContaminants to Lake Huron originate from a number of sources, including industrial and municipal discharges, spills, landfills, storm sewers, and agricultural runoff. Contaminants enter Lake Huron through a variety of pathways including direct dischar ges, atmospheric deposition, and tri exactlyary discharge. In comparison to Lakes Michigan, Erie and Ontario, contaminant concentrations are relatively low in Lake Huron. Nevertheless, public health advisories exist regarding consumption of trout from the open lake and all Areas of Concern. (Human Health and the Great Lakes April 29, 2003)www.martinfrost.ws/htmlfiles/june2008Economic Cope Zone DefinitionZone A Water level regimes that are acceptable and within the tolerance and expectations of a sector. Acceptable levels may vary by sector and location, but are mostly within the historical range and not at the extremes. Minimal economic impact. Zone B Water level regimes at which stakeholders can cope under existing policies and infrastructure, but conditions are less than ideal. Stakeholders may suffer negative impacts and may incur additional costs to minimize impacts in this zone. Marginal conditions but generally survivable. Moderate economic impact short to moderate term. Z one C Water level regimes at which stakeholders cant cope victimization existing policies and infrastructure. Sustainability is threatened for example marinas to go out of business, commercial shipping is severely curtailed, coastal properties are destroyed, significant damage to infrastructure. Severe economic impact long-term permanent loss. www.glisaclimate.org/wiki/hrwc-economics-impacts.SourcesWorld Wide Web http//www.antiessays.com/free-essays/211875.html The Lake Huron Centre for Coastal Conservation, 1998-2012. www.lakehuron.on.ca Human Health and the Great Lakes http//www.great-lakes.net
