What Makes Ingersoll's Water Unique?
Local geology and source profile
Ingersoll's drinking water is managed by the Town of Ingersoll or County of Oxford, drawing from the Thames River watershed — Ingersoll is a historic town on the Thames River in Oxford County midway between London and Woodstock, known for the world-famous Canadian cheese industry heritage (the Ingersoll Cheese Factory, where the world's largest cheese was exhibited at the 1893 World's Columbian Exposition in Chicago), and a historic manufacturing town alongside the automotive sector centred on the Toyota Motor Manufacturing Canada plant (TMMC) which produces the RAV4 and 4Runner for North American and global markets. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 182.5 mg/L (10.7 gpg) — classified as very hard by Health Canada (just above the 180 mg/L threshold), consistent with the Thames River Oxford County watershed supply character.
Ingersoll draws from the Thames River at Oxford County — the Thames in this stretch flows through the Devonian limestone and dolostone of southwestern Ontario's London Platform (Onondaga, Detroit River, and Hamilton Formations), with glacial till and carbonate sand plains contributing dissolved calcium and magnesium. The 182.5 mg/L is consistent with southwestern Ontario Thames River supply character (harder than the Ottawa River but softer than the Grand River/Waterloo dolostone supply at 229–245 mg/L), reflecting the moderate carbonate dissolution in the Oxford–Elgin segment of the Thames watershed.
At 182.5 mg/L, Ingersoll homes experience persistent scale deposits — monthly kettle and showerhead cleaning is typical. Hot water tanks benefit from periodic inspection and flushing. The Town of Ingersoll provides water quality information at ingersoll.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the historic Ingersoll downtown heritage district and the established residential streets near the Thames River valley.
Geology & Source: Supplied by the Town of Ingersoll or County of Oxford from the Thames River watershed — the Ingersoll supply from the Oxford County Thames River corridor produces very hard water at 182.5 mg/L (10.7 gpg).
