What Makes Junction Area's Water Unique?
Local geology and source profile
The Junction Area receives its water from York Region's Water Services Division, which draws from a mixed supply. This includes surface water from Lake Ontario and Lake Simcoe, supplemented by groundwater from various well stations. Major treatment facilities like the Lake Ontario Water Treatment Plant in Unionville and the Lake Simcoe Water Treatment Plant in Keswick process these sources. The utility serves over 1.1 million residents across municipalities such as Vaughan, Markham, Richmond Hill, Aurora, and Newmarket, distributing the treated water through an extensive network of pipes.
The underlying geology consists of Paleozoic limestone and dolomite formations. As water percolates through the soil or flows over these carbonate rocks, it dissolves minerals like calcium and magnesium. Groundwater, in particular, becomes harder due to extended contact with these mineral-rich sediments within regional aquifers, like those in inter-till formations. Surface waters also pick up hardness from limestone runoff within their watersheds, contributing to the overall hard water profile observed in the Junction Area.
Homeowners in areas with hard water often notice scale buildup in appliances such as kettles, coffee makers, and dishwashers, which can decrease their efficiency and shorten their lifespan. Water heaters and boilers are particularly susceptible to these mineral deposits. To combat these effects, regular descaling with vinegar, the installation of scale inhibitors, or a whole-house water softener are effective solutions. Installing a water softener is frequently recommended to protect plumbing, improve the lathering of soaps and detergents, and reduce wear on household appliances.
