Our drinking water comes from lakes, rivers, streams and underground aquifers - sources that are connected within a watershed. It is important to protect these sources of drinking water from becoming contaminated or depleted because it can be expensive or impossible to correct. This is the goal of source water protection.
May 2000 – Walkerton Tragedy
The Walkerton tragedy showed us how vulnerable our drinking water can be when it is not managed properly. An inquiry into the tragedy recommended many changes to how we manage drinking water in Ontario. The recommendations emphasized a need for source water protection and recommended it be done on a watershed basis by Conservation Authorities.
