What Makes Yonge-Eglinton's Water Unique?
Local geology and source profile
Yonge-Eglinton's water comes from the City of Toronto Water division, which supplies over 500,000 residents. The primary source is Lake Ontario, with additional water drawn from local groundwater aquifers. Treatment occurs at facilities such as the R.C. Harris Water Treatment Plant and the Island Filtration Plant. This supply serves the heart of Toronto, including the Yonge-Eglinton neighbourhood. The water's journey begins within the Lake Ontario watershed, which is influenced by the Niagara Escarpment and the Oak Ridges Moraine.
The region's geology is defined by Paleozoic limestone and shale formations. Groundwater aquifers, including those in the Simcoe Uplands, tap into these bedrock layers. Because these rocks are rich in calcium and magnesium carbonates, they dissolve minerals into the water as it flows through fractures and bedrock. This process results in a hard water profile, especially for groundwater which has had prolonged contact with the rock. Surface water from Lake Ontario also picks up minerals from limestone drainage in the watershed, contributing to the overall hardness.
Homes in Yonge-Eglinton may notice scale buildup in appliances like kettles, water heaters, and dishwashers, which can reduce efficiency and increase energy bills. Over time, pipes and fixtures can develop deposits, necessitating occasional descaling. Many homeowners opt for a water softener to combat these effects, which helps extend the lifespan of appliances and improves how effectively soap lathers. Toronto's water is generally well-treated, with pH levels typically between 7.5 and 8.5, and strict monitoring for contaminants like lead and copper.
Geology & Source: Paleozoic limestone and dolomite; soluble sedimentary rocks rich in calcium and magnesium carbonates result in a hard supply.
