Water flows through a single cycle from air to surface water and groundwater, or from land to lakes and streams, evaporating and beginning its journey all over again. But environmental law and policy often overlook an entire arc of the cycle, regulating groundwater separately and increasing the potential for risks to public health and ecosystem degradation.
The 2012 Great Lakes Water Quality Agreement is beginning to change that. One important step forward is the inclusion of an annex devoted to groundwater. Annex 8 commits the Canadian and United States governments to coordinating groundwater science and management actions. The goal is to build the base of knowledge about the impact of groundwater on the Great Lakes, leading to specific policy and science actions.
