What Makes Leamington's Water Unique?
Local geology and source profile
Leamington's drinking water is managed by the Municipality of Leamington, Canada's southernmost town on the north shore of Lake Erie in Essex County, drawing from Lake Erie via the Leamington Water Treatment Plant on the lakeshore. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 265 mg/L (15.5 gpg) — classified as very hard by Health Canada, with TDS of 607 mg/L, reflecting the extreme mineral loading of the Lake Erie source in western Essex County.
Leamington's position on the western Lake Erie shoreline places it at the heart of the Michigan Basin carbonate and evaporite province. The western Lake Erie basin receives water from the Detroit River and the Maumee and Erie watershed, all deeply influenced by Silurian Salina Formation gypsum and anhydrite evaporites and Devonian Detroit River, Lucas, and Dundee Formation limestone and dolostone that underlie the Michigan Basin from Lake Huron southward. These highly soluble formations dissolve progressively into the shallow western Lake Erie basin, producing the very high calcium and sulphate concentrations that characterise Leamington and all southwestern Essex County municipal supplies.
At 265 mg/L, Leamington homeowners face severe and persistent scale challenges. Monthly kettle descaling is essential; hot water tank elements accumulate significant scale and require annual servicing. A whole-home ion-exchange water softener is a practical and widely installed appliance throughout Essex County's greenhouse agriculture district. The Municipality of Leamington provides water quality information at leamington.ca, and water treatment specialists serving Canada's greenhouse capital region are well acquainted with managing the characteristically very hard Lake Erie supply.
Geology & Source: Supplied by Municipality of Leamington from Lake Erie via the Leamington Water Treatment Plant — Lake Erie supply at Canada's southernmost point carries extreme Silurian Salina Formation evaporite and Devonian carbonate mineral loading from the Michigan Basin at 265 mg/L (15.5 gpg).
