Each Source Protection Area submitted an Assessment Report to the Ministry of the Environment in July of 2011. They were formally accepted by the Minister and posted to the Ontario Environmental Registry on January 23, 2012.
The Assessment Reports provide detailed technical analyses and mapping of the physical and human geography of the region. A water quantity threats assessment was completed using a tiered water budget process. Any existing water quality issues were reviewed and documented. Highly vulnerable aquifers, significant groundwater recharge areas, Wellhead Protection Areas, and Intake Protection Zones were delineated and evaluated with respect to susceptibility to contamination. Human activities in vulnerable areas that are or would be significant drinking water threats were also identified.
The Assessment Report can be downloaded in it's entirety from this website. Copies are also available for inspection at the offices of the Raisin Region Conservation Authority.
