Gander Water Hardness & Quality Report (2026)

The Town of Gander Water Services Division, part of the Planning & Public Works Department, provides the municipal water supply to Gander and Gander International Airport in Newfoundland and Labrador. This public utility draws exclusively from Gander Lake, a surface reservoir situated on the Gander River system. Water undergoes treatment at the Gander Water Treatment Plant, which includes operations at two pump houses and an extensive distribution network serving urban areas and airport facilities. The utility guarantees a consistent year-round supply to homes, businesses, and institutions.

Gander Lake is located within the Gander River watershed, traversing the central Newfoundland Appalachian terrain. The region's geology is characterized by ancient metamorphic and sedimentary rocks belonging to the Paleozoic Gander Belt. Crucially, this area lacks the carbonate formations, such as limestone or dolomite, that typically contribute to water hardness in other locales. The landscape is dominated by peatlands and forested uplands, which contribute naturally occurring organic matter to the reservoir. This results in very soft water with low alkalinity, minimal dissolved minerals, and a naturally high organic colour.

Because the water is very soft, scale buildup is practically nonexistent, which is good news for appliances like water heaters, dishwashers, and coffee makers, as they are spared from mineral deposits. You'll find that soap lathers exceptionally well, potentially reducing the amount of detergent needed for laundry and cleaning. However, the presence of organics might occasionally lead to iron staining. No water softening equipment is recommended; instead, homeowners might consider filtration systems if they wish to address the water's colour and taste. Routine maintenance should involve checking for corrosion in pipes, a possibility due to the water's low buffering capacity.
