Environmental Effects Monitoring

Trinity’s Aquatic Environmental scientists are recognized as experts and have been involved in EEM since its initial development in the early 1990s and have completed numerous EEMs for the pulp and paper and mining industries.

Trinity’s Aquatic Environmental scientists are recognized as experts in the delivery of Environmental Effects Monitoring (EEM) studies as required under the Canadian Fisheries Act for several types of industrial discharges. Our scientists have been involved in EEM since its initial development in the early 1990s and have completed numerous EEMs for the pulp and paper industry (under Canada’s Pulp and Paper Effluent Regulations promulgated in 1992) and for the mining Industry (under Canada’s Metal Mining Effluent Regulations promulgated in 2002).

How We Can Help

Our scientists have presented numerous technical papers on EEM, including three technical presentations at the EEM Investigation of Cause (IOC) workshop attended by government agencies, industry, and consultant groups. Most recently, the Canadian Metal Mining Effluent Regulations were updated to the Metal and Diamond Mining Effluent Regulations (MDMER) to include diamond mines.  

Our team has completed approximately 130 EEM studies at 34 mills and mines across Canada. Based on this substantial breadth of experience, we have gained an exceptional understanding of the nuances of EEM and the associated regulations, and therefore fully understand the variety of approaches that can be applied in meeting site-specific EEM needs. We also have particular expertise and experience in application of EEM across multiple facilities located in the same area (i.e., multi-facility EEMs) and for effectively integrating EEM into broader environmental monitoring programs, both of which result in cost optimization.
