Water Quality Testing
What is the indicator and why measure it?
All water distributed in the Regional Municipality of Waterloo system must meet high levels of quality legislated by the Ontario Ministry of Environment. On an annual basis, the Region performs over 100,000 laboratory tests on drinking water obtained from groundwater sources (80%) and the Grand River (20%). This indicator, measured as a percentage of tests meeting compliance, is commonly used as a benchmark between municipalities. Proactive protection of groundwater resources is a significant focus of Water Services which aids in providing clean drinking water prior to the treatment process. Water treatment facilities, water storage reservoirs and pumping stations located throughout the Region distribute treated water to consumers.
