US & CANADA: Lake Superior clean-up recommends zero discharges

Nine critical pollutants have been prioritised for the second stage in the environmental clean-up of Lake Superior. The US EPA and Environment Canada have both endorsed a report that recommends an ultimate goal of zero discharges for the nine pollutants.


Protecting Lake Superior: Lakewide Management Plant, Stage 2, Load Reduction Targets for Critical Pollutants is the product of three years’ research and consultation. The report identifies the following nine pollutants for significant reduction:

  • dioxin
  • mercury
  • hexachlorobenzene (HCB)
  • octachlorostyrene (OCS)
  • polychlorinated biphenyls (PCBs)
  • chlordane – a pesticide
  • DDT – a pesticide
  • dieldrin – a pesticide
  • toxaphene – a pesticide

The report forms part of the Lake Superior Lakewide Management Plan (LaMP), which is part of the Binational Program to Restore and Protect the Lake Superior Basin. A binational action plan to meet the pollutant reduction targets in the report will be the next step in LaMP’s process.
