No, the Master Agreement on Apportionment has a general statement (Section 6.1) to consider groundwater matters that have implications affecting transboundary surface and groundwater. Problems can be referred to the Board who can consider recommendations. The current Agreement does not outline how groundwater should be monitored or shared across jurisdictions or how interjurisdictional issues should be addressed.
The provinces are the primary authorities to manage groundwater, and are reponsible to manage and protect groundwater quality within the province (Alberta, Saskatchewan, Manitoba). Provincial drinking water guidelines apply to both surface and groundwater water supplies.
The Committee on Groundwater and the Board is evaluating the need for a Schedule F that would provide a framework to address interjurisdictional groundwater issues. The questions of groundwater monitoring and groundwater quality objectives or targets are being considered.
