Water Quality is very much in the news these days and it is also a growing public concern. Water is one of the most important resources on the planet and affects nearly every aspect of life.

(Study mode 04, 2012) 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, and salt from roadways, agricultural chemicals, and nutrients and toxic materials from urban or rural areas (The Lake Huron Centre for Coastal Conservation, 1998-2012).
