What Makes Rexdale-Kipling's Water Unique?
Local geology and source profile
Toronto Water supplies the Rexdale-Kipling neighbourhood, located in the former City of Etobicoke, now part of Toronto. The primary water source is Lake Ontario, with treatment occurring at the R.C. Harris Water Treatment Plant and the F.J. Horgan Water Treatment Plant. In some instances, York Region may provide supplemental groundwater to portions of northwest Etobicoke. This system serves approximately 25 square kilometers, catering to residential, commercial, and industrial customers within the Rexdale-Kipling area.
The water's journey begins in the Lake Ontario watershed, which receives drainage from tributaries connected to the Niagara Escarpment and the Precambrian Shield. Beneath the lakebed and surrounding areas lie Ordovician limestones, specifically formations like the Georgian Bay and Queenston formations. As water interacts with these bedrock layers and the overlying glacial tills found in regional aquifers, it dissolves carbonate minerals. This geological makeup, rich in limestone, is the reason for the consistently hard water supply observed throughout the Greater Toronto Area.
Homeowners in Rexdale-Kipling may notice scale accumulating in appliances such as water heaters, dishwashers, and coffee makers, which can impact their efficiency and longevity. You might also find stubborn spots on fixtures and experience reduced lathering from soaps and detergents. To combat these effects and prolong the life of your appliances, installing a water softener is often recommended. Fortunately, Toronto water consistently meets provincial drinking water standards, with recent pipe replacement programs helping to maintain low levels of lead and copper. Trace levels of PFAS are also reported to be well below Health Canada guidelines.
