Water Quality, Ecotoxicology, Fisheries and Aquatic Resources
We provide clients a highly experienced team with broad technical depth and practical expertise. Our focus is on studies involving aquatic biology, ecotoxicology, water quality, fisheries and fisheries resources.
Whether conducting baseline studies, obtaining permits to do work in a watercourse, designing an innovative study to identify causes of impacts in a receiver, providing strategic advice or review; if it’s related to water and aquatic resources, Ecoreg Solutions can help.

Hydrology and Fluvial Geomorphology
To complement our aquatic resources expertise, Ecoreg Solutions conducts hydrological and water quality modeling work to characterize receiving environments and inform water management decision-making. We also study and map stream morphology, function, erosion and design. This work is completed as part of baseline characterization, during designing and planning, or operations and closure.
Receiving water assessments
Effluent dispersion and assimilative capacity modeling
Plume delineations
Effluent water quality modeling and management
Hydrological studies (flow, quantity, quality) and loadings investigations
Watershed and subwatershed studies, planning and development
Erosion and stream restoration studies
Channel inventories and geomorphological assessments
Meander belt assessment
Environmental Permitting and Regulatory Compliance
Project development activities conducted by our clients are subject to complicated, sometimes overlapping federal, provincial and local environmental permitting requirements. We work with you and regulatory agencies providing strategic advice to negotiate and obtain permits and approvals. Ecoreg also provides expert testimony at hearings.
Department of Fisheries and Oceans (DFO) Fisheries Act Authorizations and Offsetting Plans (i.e. stream diversions, water crossings, bridges, culverts)
Metal and Diamond Mining (MDMER) and Pulp and Paper Effluent Regulations (PPER) Environmental Effects Monitoring, Schedule 2 Listings
Federal and Provincial Environmental Assessment Legislation
Ministry of Natural Resources and Forestry (MNRF) Acts, Licences and Approvals

Environmental Assessment
The regulatory framework can be complex when navigating federal and provincial requirements, especially when developing a large-scale green or brownfield project. Our team has worked on small to large-scale environmental assessments across central and eastern Canada.
Critical issues identification, environmental gap analysis
High level environmental analysis at PEA, PFS, FS levels
Early regulatory support or regulatory roadmaps around project interactions with water and fisheries resources
Baseline studies (water quality, fisheries and aquatic resources)
Technical water and/or aquatic environmental assessment partner (EIA, EIS)
Toxicological assessments, delineation of historical impacts
Surface water supply and management
Experienced working with EA geochemists, hydrogeologists, geologists and mining engineers, human and ecological risk assessors
Stakeholder and agency engagement and meetings
Site Closure and Reclamation
Our experience in acid mine drainage and mine wastewater remediation and reclamation work spans almost three decades. Important at the commissioning and closure stages, this work has become increasingly important in assessing site water risk and long-term environmental objectives.
Ecoreg senior management has worked on many multi- year pre- and post-reclamation projects as part of large multidisciplinary teams. One long term project involved the first HDPE cover to be successfully used in Canada (1994-2011).
Conceptual closure strategy and reclamation planning
Contaminated site assessment
Development of remedial objectives and benchmarks
Progressive reclamation planning, implementation and management, working with engineers
Pre- and post-reclamation biomonitoring
Long term tailings and water management studies
Closure compliance monitoring
Participation in public outreach and Aboriginal engagement
Research and Development
Ecoreg Solutions believes strongly in innovation and supporting research that leads to better environmental decision making. We can help you find ways to leverage existing work, available grants or funding sources and academic partners.
We have a proven track record for developing partnerships and using research and innovation to solve problems for industry. Ecoreg Solutions ongoing research includes:
Mine Wastewater Solutions: Application of Genomics Technologies to Understand Microbes and Improve Strategies to Manage Mine Wastewaters. EcoReg Solutions is a partner in a five-year international research project led by Professor Lesley Warren, Chair in Mineral Engineering at University of Toronto. Research is funded by Genome Canada, Ontario Genomics and Ontario Research Fund. The outcome will be very useful to mining companies providing information for more passive mine wastewater treatment options both during operations and after closure.
Ontario Genomics research project with our industry partners in progress to develop DNA-based methods of identifying benthic invertebrates, which could provide an accurate and time efficient method for future biomonitoring. The research will help to develop appropriate standard methods.
Ecoreg Solutions co-authored a publication in Aquatic Toxicology (Sept. 2018) based on an NSERC CRD – Subcellular partitioning of metals and metalloids (As, Cd, Cu, Se and Zn) in liver and gonads of wild White Suckers (Catostomus commersonii) collected downstream from a mining operation. The research led to important insights into metal handling strategies in fish and causes of observed effects, as well as providing valuable data for risk assessment and environmental site management.
Arsenic Bioavailability, Bioaccumulation and Toxicity – EcoReg Solutions is involved in several innovative arsenic projects using biogeochemistry, bioavailability and alternative arsenic speciation techniques to assess arsenic species in biota and arsenic movement and risks at historically contaminated sites.
