Drinking Water Source Protection

Source water is untreated water from lakes, streams, and aquifers that is used to supply municipal drinking water systems. Protecting source water simply means to protect this water from overuse or contamination due to pathogens or chemicals. This will ensure that there is enough safe water for all designated uses – for now and in the future.

The Ontario government passed the Clean Water Act in 2006 to protect these sources of municipal drinking water supplies throughout Ontario. Under the Act, 19 source protection regions were designated in Ontario.
