What we've done

---

Operating independently since 2015, Jay Toews P. Biol., R.P.Bio., C.Chem., P.Chem. has led a diverse collection of projects, including:

• A study determining that non-compliant turbidity in potable water was caused by algae species succession in a drinking water reservoir rather than chemical processes in the reservoir or treatment plant.

• Calculation of whole-lake nutrient budgets, including external and internal phosphorus loading, through analysis of algal taxonomy, chemistry and hydrological data, after training local Conservation District staff in data collection methods.

• Interpretation of chemistry and algae taxonomy data to provide guidance to water quality improvement strategies in lakes in Alberta and Quebec.

• Development of a water quality model for a 105-km reach of a river receiving historical and ongoing nutrient loading from agricultural runoff and wastewater effluents.

• Research, pioneering novel, non-destructive sampling techniques, on protected freshwater mussel species in turbid river environments.

• Project Management and technical leadership for a program that included assessment of water quality and harmful algal blooms, fish habitat, hydrotechnical and geotechnical engineering studies, as well as an extensive community engagement program, to develop a Water Level Management Plan and design criteria for lake control structure, thus resolving long-standing conflictual challenges in a divided community.

• Senior advisory and review support to Environmental Assessments for three mines in British Columbia, including site-specific toxicity studies and development of regulatory discharge criteria.

• Completion of the Federal Review Process and contribution to design specifications for dam construction and shoreline stabilization projects on First Nations lands.

• Environmental permitting and mitigation plan development for seven riverbank stabilization projects in locations inhabited by Species At Risk.

• Environmental permitting and co-authorship of the Preliminary Design and Remedial Action Plan for a contaminated site on the Souris River in Saskatchewan.

• Creation of an Ecological Inventory Workplan and a long-term Programming Strategic Plan for development of the East Braintree Boreal Ecology Centre.

Jay is the current Northern and Western Canada Director for the North American Lake Management Society.  Jay is also honoured to serve as a scientific advisor to A Rocha Manitoba and the Riding Mountain UNESCO Biosphere Reserve.
