An aquatic expert warns that despite improved policies and extensive clean-up, the Great Lakes remain stressed and threatened.

Doug Haffner, the senior Canada research chair in Great Lakes Research at the University of Windsor, says a number of pollutant abatement programs implemented since the 1960s had a positive impact on the lakes.

“However, we have new issues. The Great Lakes have many different stresses on them right now,” Haffner said.

Chemicals of concern

  • Cosmetics.
  • Paints.
  • Electronics.
  • Fertilizers.
  • Fragrances.
  • Disinfectants.
  • Pesticides.

He said one newer concern is pharmaceutical waste.


“The other factor is climate change,” Haffner said.

Warmer water temperatures increase the amount of toxic algae that grows in the Great Lakes. Lake Erie is particularly vulnerable because it’s the shallowest of the Great Lakes.
