What Makes Saint-Lazare's Water Unique?
Local geology and source profile
Saint-Lazare, a municipality situated west of Montreal, Quebec, receives its water supply from the Ville de Saint-Lazare municipal utility. The water originates from groundwater aquifers located within the St. Lawrence Lowlands region. The municipality actively manages a water source protection plan, with its most recent update following a groundwater vulnerability assessment conducted in 2021. Water undergoes treatment and is regularly analyzed by certified laboratories to guarantee its safety and adherence to drinking water standards.
The Saint-Lazare water supply is drawn from Ordovician and Cambrian sedimentary aquifers, which are typical of the St. Lawrence Lowlands. These geological formations are mainly composed of limestone and dolomite bedrock. This bedrock readily dissolves in groundwater, leading to significant concentrations of dissolved calcium and magnesium. This particular geological setting is the reason behind the hard water supply commonly found in the area, and the carbonate-rich geology dictates the mineral content of the water throughout its time in the aquifer.
Homeowners in Saint-Lazare might notice scale buildup on pipes, decreased efficiency in their water heaters, and spotting on dishes due to the water's hardness. Soaps and detergents may also be less effective. Appliances like dishwashers, washing machines, and water heaters are particularly susceptible to the effects of hard water. Residents are encouraged to clean or replace filters more often, especially if they observe high sediment concentrations, which typically result from mineral precipitation. Installing a water softener could also help reduce mineral deposits, improve cleaning effectiveness, and extend the lifespan of appliances.
