Pincourt Water Hardness & Quality Report (2026)

Pincourt's drinking water is managed by the Ville de Pincourt, drawing from the Ottawa River or Lac des Deux-Montagnes — Pincourt is a suburb on Île-Perrot, the large island at the confluence of the Ottawa and St. Lawrence Rivers at the western end of the Island of Montreal, a bedroom community connected to the Island of Montreal by the Île-Perrot Bridge and the Autoroute 20-40 interchange, home to a suburban Quebec community with deep roots in the île-Perrot agricultural heritage and the modern suburban residential development of the Montérégie-Laurentides west island corridor. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 79.5 mg/L (4.6 gpg) — classified as moderately hard by Health Canada, consistent with the Ottawa River west-island supply.

Pincourt draws from the Ottawa River / Lac des Deux-Montagnes on the west side of the Montréal archipelago — at Île-Perrot, the water draws from the Ottawa River before it meets the St. Lawrence. The Ottawa River supply at this point carries dissolved Precambrian Canadian Shield minerals mixed with the lower Ottawa Valley carbonate lowland input, producing moderately hard water at 79.5 mg/L — softer than the main Montréal West Island supply (110.5–115.5 mg/L from reference data) but reflecting the specific Île-Perrot Ottawa River intake at the Lake of Two Mountains. Water quality reports are published under Ministère de l'Environnement oversight.

At 79.5 mg/L, Pincourt homes experience light scale deposits — cleaning every two months is adequate. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Île-Perrot residential neighbourhoods near the Lac des Deux-Montagnes waterfront.
