Pollution in the Great Lakes

"Today roughly one-quarter of Canada's population drink from the Great Lakes" (Walker, 2013).

Pollution in the Great Lakes has been a concern since the 60s when high levels of phosphates were found in the lakes due to household detergents. Water is the universal solvent and does not distinguish between good and bad solutes. Once pollutants have been dissolved in water, it can be difficult to impossible to remove them from bodies of water.
