What Makes Edmundston's Water Unique?
Local geology and source profile
The City of Edmundston, New Brunswick, draws its drinking water from the Rivière-Verte (Green River). This surface water supply flows into the city's treatment facilities, serving residents in the Madawaska region. Public works officials note that the Rivière-Verte provides relatively clean raw water, meaning treatment requirements are minimal. The watershed itself is located in the Appalachian physiographic region of northwestern New Brunswick.
The underlying geology features Paleozoic sedimentary and metamorphic bedrock, with geological formations rich in carbonates. This composition naturally leaches minerals, such as calcium and magnesium carbonates, into the Rivière-Verte. This process results in a water supply that is characteristically hard for the region, with a moderate mineral content.
Homeowners in Edmundston might notice that this hard water reduces soap lathering and can lead to mineral buildup on fixtures and appliances. Spotting on dishes and glassware is also common. Appliances like water heaters and dishwashers are particularly vulnerable to scale accumulation. Consider installing point-of-use water softeners for high-temperature applications, and regularly descale appliances. Using chelating agents in cleaning products can also help manage mineral deposit issues.
Geology & Source: Paleozoic sedimentary and metamorphic bedrock; carbonate-rich formations produce moderate to hard water
