Drinking Water Protection Zone is an official designation in the Canadian province of Ontario for areas that feed a well or municipal water supply. Road signs identify a “Drinking Water Protection Zone” with a graphic of a water glass. These signs are a standardized sign being used across the province to indicate areas where a spill of toxic liquids including oil could impact a source of water for a municipal drinking water system.
Criteria for location of road signs
The road signs indicate intake protection zones and wellhead protection areas around the municipal drinking water systems where a spill could be a significant drinking water threat. These zones were determined by calculating how quickly surface water and groundwater move toward municipal intakes and wells.
Purpose of the signs
The primary purpose of the signs is to remind first responders the locations where a spill could impact a municipal drinking water source. In the event of a spill in the drinking water protection zones it is important to notify the appropriate authorities including the Ontario government's Spills Action Centre and the operators of the municipal drinking systems that a spill has occurred. It may be necessary for the operator to shut down the system so that contaminants do not enter the system.
A secondary purpose is to raise public awareness of the Source Protection Program. Many people do not know or consider where their water comes from and that human activities on the land can negatively impact the quality of the drinking water. It is therefore a key component of the overall education and outreach efforts of the Source Protection Committees across the province.
