Source Water Protection

A Drinking Water Protection Zone sign displayed next to a road way.

More than 80 per cent of Ontario’s population receives their drinking water from a municipal drinking water system. Municipalities, source protection authorities and others all play a strong role in ensuring that municipally treated drinking water is safe for our use (Conservation Ontario, 2021).

The following resources were collected for their relevance to source water protection planning.
