Tables of Drinking Water Threats

We've made tables that include the 21 drinking water quality threat activities, set out in O. Reg. 287/07, which may pose a risk to a municipal drinking water supply. The tables also provide all the circumstances associated with each threat.

The tables separate drinking water quality threats into two sections: chemical and pathogen.
