Templeton-Est Water Hardness & Quality Report (2026)

Templeton-Est (a residential neighbourhood in the eastern sector of Gatineau, Quebec — located in the former Buckingham–Masson–Angers corridor in the Outaouais region, east of the main Hull–Aylmer urban core of Gatineau along the Ottawa River's north shore) receives its drinking water from Ville de Gatineau, drawing from the Ottawa River via the Gatineau regional water treatment system serving all of Gatineau's sectors. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 104 mg/L (6.1 gpg) — classified as moderately hard by Health Canada, consistent with the Ottawa River corridor supply character.

Templeton-Est's 104 mg/L reflects the Ottawa River supply at the Gatineau intake — the Ottawa River drains the Grenville Province of the Canadian Shield through the Outaouais region, passing through sections with Ordovician limestone outcrops in the Ottawa Embayment that contribute dissolved calcium, producing the moderately hard ~100–120 mg/L supply characteristic of the Ottawa–Gatineau area. Templeton-Est's 104 mg/L is consistent with the Ottawa/Gatineau supply range, slightly softer than the City of Ottawa's typical 116–120 mg/L, reflecting the eastern Gatineau distribution sub-zone's specific supply characteristics.

At 104 mg/L, Templeton-Est residents experience moderate scale deposits — cleaning every six to eight weeks is adequate. Hot water tanks operate reliably at this hardness. Ville de Gatineau publishes annual water quality reports following Ministère de l'Environnement standards. Health Canada lead precautionary guidance applies to residents in Templeton-Est's older pre-1975 residential properties in the historic Buckingham sector.
