Environmental Effects Monitoring

Environmental Effects Monitoring (EEM) studies are conducted by industries to identify potential effects caused by effluents on fish, fish habitat and use by humans of fish.

EEM is a science-based performance measurement tool used to evaluate the adequacy of effluent regulation in protecting fish, fish habitats and the usability of fisheries resources.

EEM studies can include:

  • water quality monitoring
  • effluent chemical characterization
  • effluent sublethal toxicity testing
  • biological monitoring in the receiving environment
