Assessment Report

The Assessment Report is a technical document that looks at the watershed in its entirety, the Assessment Report provides information about ground and surface water characteristics for each municipal drinking water system.  This report brings together key findings about the source water in the Greater Sudbury Source Protection Area and includes information about the amount of water available for drinking and the quality of the water.DWSP-testing-water

The Assessment Report contains the technical and scientific information the Source Protection Committee requires to develop the Source Protection Plan, including:

  • watershed characterization
  • groundwater vulnerability
  • surface water vulnerability
  • water quantity analysis
  • water quality threats and issues

This document identifies vulnerable areas for both groundwater and surface water sources, along with activities that pose a risk to the quality and quantity of drinking water sources within the Source Protection Area. Identified risks to water quality and quantity are ranked as low, moderate or significant threats on a scale from 0 to 100, with significant threats scoring above 80. The priority risks identified in the Assessment Report will be the first ones considered during the development of the Source Protection Plan.
