Search a location to see if it is in a vulnerable area – that is, close to a municipal drinking water well or other drinking water intake. In these areas certain land or water activities, if left unchecked, could pollute the water supply. If your location is in a vulnerable area, follow the link to the Help section, identify the threats for the zone, check the policy tab and if needed go to the source protection plan to find out what activities are prohibited or need to be managed.
You may also follow the link to the Threats Tool, in the Help section to identify what activities pose a threat to drinking water sources in the zone.

Find out if the property you are looking at has land-use restrictions because ground or surface water is nearby. This map also gives you vital information you’ll need to complete your application for a provincial Environmental Compliance Approval (ECA). See all ECAs at Access Environment.
Find out if the property site has restrictions affecting animal penning, manure storage or fertilizer use. You may also wish to view the Agricultural Atlas.
Find vulnerable areas to help when issuing building permits, developing Official Plans, plotting utility or transportation corridors, or creating risk management plans.
Find out if the property you want to buy has specific requirements, e.g., a fuel tank must be above ground.
