The Approved Assessment Report was a required element in the development of the Source Protection Plan. The report contains the technical and scientific information that the Source Protection Committee used to develop the Mattagami Region Source Protection Plan.
The Report assesses the state of the City of Timmins municipal drinking water source – the Mattagami River. It describes the amount of water that is available for drinking and the quality of that water.
The Assessment Report also describes the vulnerable areas around the municipal drinking water system where spills, pollution, contamination and overuse could harm source water.
