This Watershed Characterization Report, a snapshot of the drinking water source situation within the Mississippi and Rideau watersheds in Eastern Ontario, is the first product in the process. Parts of this report plus other technical "modules" (vulnerability analysis, threats inventory, water quality and quantity risk assessments) will eventually be brought together to form the Assessment Report detailing the issues around drinking water sources. Finally, a detailed Source Protection Plan for each watershed will be developed with full public participation in which current threats to municipal drinking water will be reduced and future threats will be reduced or eliminated.
