Threats to Groundwater Supplies in Canada Require Coordinated Response: C.D. Howe Institute
TORONTO, Feb. 10 /CNW/
– Better oversight of Canada’s groundwater resources is required in the face of numerous challenges, according to a study released today by the C.D. Howe Institute.
In ” Protecting Groundwater: The Invisible and Vital Resource, ” James Bruce, recently chair of the Council of Canadian Academies Expert Panel on Groundwater, assesses present and emerging threats and makes recommendations for better groundwater management in Canada.

Challenges for groundwater management, the author says, include energy issues, such as the uncertain impact of shale gas “fracking,” slow recharge rates of aquifers, agricultural intensification, and contamination. Canada has yet to experience large-scale over-exploitation of groundwater resources and its groundwater remains of good quality.
Bruce says the time is right, however, for establishing the legal, regulatory and management systems, along with the necessary monitoring provisions, to overcome the threats to groundwater.
Nearly 10 million Canadians, including about 80 percent of the rural population and many small- to medium-sized municipalities, rely on groundwater for their everyday needs. However, Canadians living in large cities and most policymakers tend to ignore groundwater and its management. This asymmetry of interests has resulted in fragmented knowledge of groundwater locations, their quantity, quality, and how groundwater supplies are changing over time in Canada.
Bruce says an effective groundwater management strategy would adhere to five major principles for sustainability. They are: protection from depletion; protection from contamination; ecosystem viability; allocation to maximize groundwater’s contribution to social and economic well-being; and the application of good governance.
Given the challenges that lie ahead, the author concludes, meaningful cooperation by three levels of government, as well as prices that better match the costs of delivering water and wastewater services, and an expansion in data collection efforts are required to sustainably manage Canada’s groundwater.
