The Multi-Barrier Approach: What goes into keeping your drinking water clean听
In Ontario, most municipalities have the privilege of accessing safe and clean drinking water simply by turning on a tap. This is made possible by unique legislation designed to protect municipal drinking water from source to tap. A multi-barrier approach to ensuring water safety was introduced following the tragic Walkerton, Ontario incident in 2000. This approach aims to keep contaminated water from reaching consumers by implementing multiple layers of protection.鈥�听听
The multi-barrier approach involves a combination of processes and procedures to prevent and reduce contamination in drinking water. There is no single solution that can fully safeguard a water system; instead, multiple methods must work together to minimize and eliminate contamination. This approach also includes creating safeguards and contingency plans to quickly respond听to emergencies and ensuring system redundancies to mitigate potential negative impacts.鈥�听
Source Water Protection is the initial step in this process. By safeguarding the sources of drinking water鈥攕uch as rivers, aquifers, and lakes鈥攚e ensure their cleanliness. Ontario鈥檚 Clean Water Act supports this protection through Source Protection Plans across the province.鈥�听
The Safe Drinking Water Act mandates that water treatment systems are in place to ensure you can #TrustTheTap for safe drinking water. Water must be treated to remove or reduce harmful contaminants and organisms. Municipal drinking water systems are subject to inspections to ensure compliance with regulations. Trained and certified operators routinely test water quality, and corrective actions are taken if any issues are detected. The distribution system, including pipes and pumping stations, is also tested and disinfected to ensure safe water delivery right to your homes.鈥�听
More than 80% of Ontario’s population receives drinking water from municipal systems. Ensuring safe and abundant drinking water is crucial for public health, and protecting it is a shared responsibility. With robust legislative and regulatory frameworks in place, Ontario鈥檚 drinking water remains clean and safe from source to tap.鈥�听
