What Makes Kingsville's Water Unique?
Local geology and source profile
Kingsville's drinking water is managed by the Town of Kingsville (Canada's southernmost municipality, on the north shore of Lake Erie in Essex County — known as the 'Greenhouse Capital of North America' for its vast greenhouse vegetable production), drawing from Lake Erie via the Essex County regional water supply system. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 301 mg/L (17.6 gpg) — classified as very hard by Health Canada, with TDS of 760 mg/L and pH 8.4 — among the highest measured in any batch in this dataset, reflecting Lake Erie's exceptional mineral richness.
Lake Erie is the shallowest Great Lake (mean depth 19 m) and its water has the longest residence time in contact with the extremely soluble Devonian Onondaga Formation limestone and dolostone and Silurian A-1 Evaporite (gypsum, anhydrite) bedrock that forms the Erie basin floor across Ohio, Pennsylvania, and Ontario. This prolonged mineral contact at Kingsville's southernmost Ontario intake produces very high dissolved calcium and sulphate concentrations — TDS of 760 mg/L and pH 8.4 confirming significant bicarbonate and carbonate saturation. Kingsville's 301 mg/L is notably harder than the Tecumseh (271.5 mg/L) and Windsor (255 mg/L) Lake St. Clair supply to the north, making it one of the hardest municipal supplies documented in southwestern Ontario.
At 301 mg/L, Kingsville homeowners face some of Ontario's most severe scale problems — kettle elements and showerhead fixtures require weekly cleaning. Hot water tank elements accumulate heavy scale; biannual inspection and servicing are warranted. A whole-home water softener is an essential appliance throughout the Lake Erie shore communities of Essex County. The Town of Kingsville provides water quality information at kingsville.ca.
Geology & Source: Supplied by Town of Kingsville from Lake Erie via the Essex County regional water supply system — Lake Erie water from the shallowest Great Lake, with extreme Devonian dolostone, limestone, and evaporite mineral loading, produces the hardest recorded supply in the batch at 301 mg/L (17.6 gpg).
