Hatfield is a global leader in studying the aquatic effects of industrial and municipal effluents, and developing acceptable water quality thresholds for specific aquatic environments. Our diverse range of effects monitoring and ecotoxicology services include:
- Complete design and implementation of aquatic effects monitoring programs, such as the Canadian Environmental Effects Monitoring (EEM) program and similar programs, to assess the effects of effluents from metal and coal mines, pulp and paper mills, oil sands facilities, and municipal discharges;
- Developing site-specific water quality thresholds for metals and ions in aquatic environments, using toxicity-based methods, ranges of natural variability, and/or inputs from affected local communities;
- Toxicity Identification Evaluations (TIE) that identify specific constituents of industrial effluents causing environmental effects;
- State-of-the-environment assessments including comprehensive reviews and statistical assessments of historical monitoring results; and
- Quantitative risk assessments of contaminants in the environment.
Hatfield’s experienced multi-disciplinary team has expertise in diverse areas of aquatic environmental science and monitoring. Our staff have been heavily involved in the development and implementation of federal EEM programs for the pulp and paper and metal-mining sectors since the 1990s; we implement the majority of such EEMs in Western Canada today, in addition to implementing numerous similar discharge-specific or regional monitoring programs associated with coal mines, oil sands facilities and municipal discharges. We have designed and implemented similar programs internationally, in Southeast Asia and elsewhere, and have advised international clients on effective and efficient monitoring program design.
