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 ...view middle of the document...
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 miles of surface area has made it very vulnerable to atmospheric deposition of contaminants. This is the major cause of pollution to Lake Huron because it has few local contaminant point sources. Sediments and land runoff are continual sources of pollution to Lake Huron. Some of the toxins include phosphorus, dieldrin, DDT, furans, dioxin and PCB’s.

The pollution in Lake Huron has a negative effect on people and the economy of the area. Phosphorus levels threaten the safety of drinking water because of the harmful algae blooms. Deficient oxygen levels because of excessive algae growth makes the fish communities unstable and harmful for consumption. It can cause the extinction of a specifies which disrupts nature’s balance and creates harm to other species. The economic affects are just as devastating. Lake Huron beaches are enjoyed for local residents and tourists every year. The pollution in Lake Huron will reduce the tourism to the area and cause local residents to go elsewhere to spend their money. Property values decline due to the loss or tourism and recreational opportunities. Protecting the drinking water adds costs to the public industries, and government.

The contamination of Lake Huron has been ongoing for the past couple centuries. People, wildlife and the economy is heavily affected by the pollution from health, extinction of species to loss of revenues. The government and other countries have established programs to help combat the problems of pollution but there are still many pollutants that affect the ecosystem today.
