Source Water Protection

Source water is untreated water from streams, lakes, rivers or underground aquifers that people use for potable water supply. Protecting source water is a team effort, a collaboration between Source Protection Authorities, municipalities, the province, and community members.

What is source water protection?

Source water protection protects Ontario's municipal drinking water from overuse and contamination, and complements water treatment and monitoring by reducing risks to water supplies in the first place.

Threats to source water

The provincial government identified 21 significant threats to our drinking water, from waste management and sewage to road salt and pesticides. The level of risk they pose depends on the nature of the threat and its location.

Vulnerable areas

There are four categories of areas defined by the Clean Water Act as in need of protection. These “vulnerable areas” include:

Wellhead Protection Areas
Intake Protection Zones
Significant Groundwater Recharge Areas
Highly Vulnerable Aquifers
