What Makes Rivière-du-Loup's Water Unique?

Local geology and source profile

Source: RiverTDS: 45.5 mg/LpH: 7

Ville de Rivière-du-Loup draws its water from the Rivière du Loup or a reservoir within the Notre-Dame Mountains watershed. This supply, originating from the Appalachian Highlands on the south shore of the Bas-Saint-Laurent, undergoes treatment at a local facility before reaching consumers.

The water's exceptional softness is a direct result of its geological origins. It flows through the metavolcanic and metasedimentary rocks of the Appalachian Highlands, a terrain that contributes very few dissolved minerals, particularly calcium and magnesium, to the water supply.

This very soft water means you might need to use less soap and detergent to get a good lather. Over time, it generally won't cause scale buildup in your pipes or appliances like water heaters or dishwashers. Some people find the taste different from harder water, but it poses no health risks and is safe for all household uses.
