What Makes Willowridge-Martingrove-Richview's Water Unique?
Local geology and source profile
Willowridge-Martingrove-Richview, a Toronto neighbourhood, receives its water from City of Toronto Water, a division of Toronto Water. The main supply comes from Lake Ontario, which is processed at the R.C. Harris Water Treatment Plant and the F.J. Horgan Water Treatment Plant. These facilities treat the surface water, occasionally blending it with groundwater from the regional system if necessary. The water originates from the Lake Ontario watershed, part of the vast Great Lakes Basin, and is delivered to residents in Etobicoke and across the Greater Toronto Area.
The geology beneath Willowridge-Martingrove-Richview consists of Ordovician-Silurian limestones and dolomites, including formations like the Queenston Formation. These bedrock types are rich in calcium and magnesium carbonates. As water interacts with these soluble Paleozoic rocks, these minerals dissolve, contributing to the naturally hard character of both the surface water from Lake Ontario and any groundwater that might be used. This process is typical for the region's karst terrain.
Homeowners in this area will likely notice scale buildup on faucets, in kettles, and inside appliances like dishwashers and washing machines. This mineral deposit reduces the efficiency of water heaters and other fixtures, potentially increasing energy costs by up to 30%. To combat this, regular descaling with vinegar or installing a whole-house water softener is often recommended. Toronto Water also works to control corrosion by maintaining a pH between 7.2-8.0 and has reported full compliance with lead and copper regulations, with ongoing service line replacement projects.
Geology & Source: Great Lakes watershed - Lake Ontario; Paleozoic limestone and dolostone (Ordovician-Silurian, Georgian Bay Formation, Lindsay Formation) readily dissolve calcium and magnesium, creating hard water.
