What Makes Gander's Water Unique?
Local geology and source profile
Gander's drinking water is managed by the Town of Gander, drawing from a local central Newfoundland reservoir — Gander is the aviation city of Newfoundland and Labrador, built around the historic Gander International Airport (once the world's transatlantic aviation hub) in the boreal interior of central Newfoundland, the community immortalised in the musical 'Come From Away' for its extraordinary hospitality during the September 11 diversion when 38 aircraft carrying 6,579 passengers were diverted to Gander, stranding them for five days while the entire Gander community opened its homes, schools, and churches to the stranded travellers, a defining story of Newfoundland warmth and generosity. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 40.5 mg/L (2.4 gpg) — classified as soft by Health Canada, consistent with the central Newfoundland reservoir supply character.
Gander draws from a local central Newfoundland reservoir in the boreal Shield country of the Gander Lake–Exploits River watershed — the Gander area sits on Precambrian and Cambrian granitic and metasedimentary rocks of the Gander Zone (Gondwana-derived Avalonia terrane) in the central Newfoundland Shield, with essentially pure bedrock catchment terrain producing very low mineral runoff. The 40.5 mg/L for Gander is at the upper end of the NL reference range (6.5–33.5 mg/L from reference data), slightly higher than the pure granitic Shield supplies, reflecting some marginal carbonate input from local Cambrian carbonate lithologies in the Gander Zone.
With 40.5 mg/L, Gander homes are essentially scale-free — occasional kettle cleaning every three months is adequate. Hot water tanks have an excellent operational lifespan. The Town of Gander provides water quality information at gandercanada.com. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Gander townsite near the Gander International Airport heritage buildings.
Geology & Source: Supplied by the Town of Gander from a local central Newfoundland reservoir — the Gander supply from the Newfoundland Shield watershed produces soft water at 40.5 mg/L (2.4 gpg), consistent with the central Newfoundland reservoir supply character.
