Source Protection Information Atlas

The Source Protection Information Atlas enables anyone to determine if an address is within a Source Protection Vulnerable Area. The map displays over 20 layers of Source Protection data for Ontario. The map uses a ESRI_GEOCORTEX API (Application Programming Interface). There are 4 vulnerable area types that surround municipal water supplies: Wellhead Protection Areas, Intake Protection Zones, Significant Groundwater Recharge Areas and Highly Vulnerable Aquifers. For details on the assessment reports and plans that contain definitions of these zones please click on one of these links. For access to the raw data contact the Conservation Authority for the jurisdiction you are interested in.

These assessments were documented in 38 local assessment reports that were approved by the ministry. The data collected from these reports form the foundation for the Source Water Protection Mapping Tool. This interactive map allows you to search for a location in Ontario and determine if it is in a Source Protection vulnerable area. The map will show the location information, vulnerable zone type and score, as well as provide link(s) to local source protection plans where you can find the policies associated with the search location. Searches can be performed by street address, geographic coordinates or several other search options listed in the help. Confirm the location by using the satellite imagery. Please note that searches by geographic coordinates (Lat. and Long) will return the most accurate results. Searches performed with a street address, postal code, municipality, lot, concession or township may require you to further refine the location by moving the pin to the accurate location based on your knowledge of the site. Please refer to the help (Primary Navigation Pane) for tips on searching, and the proper syntax of your searches. Questions?
