source water protection

Source water protection is protecting water sources from overuse and contamination. This helps to safeguard public health.

In Ontario, source water protection is carried out under the Clean Water Act, 2006. Source water protection is considered the “first barrier” of a multi-barrier approach to providing safe drinking water. Other barriers are effective water treatment, proper distribution, operator training and adequate water testing.

Source water is untreated surface water and groundwater that people use to supply drinking water systems.

Municipalities obtain water for municipal distribution and public use from both groundwater and surface water sources.

Groundwater is drawn from wells drilled into an underlying aquifer, which is the water source.

Surface water sources include lakes, rivers and bays such as the Bay of Quinte, Lake Ontario, Roblin Lake and the Napanee River. Surface water is drawn through intakes (pipes) in the surface water.

The Municipality of Marmora and Lake has one municipal system (Village of Marmora) in the Trent Conservation Coalition Source Protection Region and another (Village of Deloro) in the Quinte Source Protection Region.


Business developers

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).

Farm Owners

Find out if the property site has restrictions affecting animal penning, manure storage or fertilizer use.


Find vulnerable areas to help when issuing building permits, developing Official Plans, plotting utility or transportation corridors, or creating risk management plans.

Prospective home owners

Find out if the property you want to buy has specific requirements.

The following links can be used to search if your property is in a vulnerable area (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 source protection plan to find out what activities are prohibited or need to be managed.
