What Makes Saint-Bruno-de-Montarville's Water Unique?
Local geology and source profile
Residents of Saint-Bruno-de-Montarville receive their water from the Ville de Saint-Bruno-de-Montarville, which is part of the Montérégie regional south shore system. This system draws its supply directly from the St. Lawrence River. The water treatment process, aimed at delivering safe and clean drinking water, is managed to meet the needs of the community served by this expansive municipal network. This river serves as the primary source for a significant population.
The Montarville highland supply, situated on the south shore of Montréal, draws from the St. Lawrence River. This area's geology contributes to the water's characteristics. The underlying rock formations in the Montérégie region are predominantly sedimentary. These types of rocks often contain minerals that dissolve into the water, resulting in a moderately hard water profile for the Montarville supply.
With water hardness reported at 7.0 grains per gallon, homeowners might notice some effects on their appliances. Over time, mineral buildup can occur in pipes and water heaters, potentially reducing their efficiency and lifespan. Using slightly more soap or detergent for laundry and dishes is common with moderately hard water. Regular descaling of fixtures and appliances can help mitigate these effects. A water softener is an option for those seeking to reduce the mineral content further.
Geology & Source: Montérégie highlands; sedimentary rocks produce moderately hard water
