What Makes La Haute-Saint-Charles's Water Unique?
Local geology and source profile
Water for the La Haute-Saint-Charles district comes from the Ville de Québec municipal system. This supply originates from the Rivière Saint-Charles and Lac Saint-Charles, located in the northern highlands of Quebec City. The exact treatment facilities and processes used by Ville de Québec are not detailed in the available information, and official water quality reports were not accessible. Residents seeking specific details on treatment, hardness levels, or any detected contaminants should contact the Ville de Québec water department directly.
This water originates from the Precambrian Laurentian Shield, a vast geological area known for its ancient igneous and metamorphic rocks. As water flows through this terrain, it picks up very few dissolved minerals. Consequently, the water supplied to La Haute-Saint-Charles is notably soft, registering at only 2.9 grains per gallon (gpg). This geological characteristic is the primary reason for the water's low mineral content and soft nature.
Because the water is very soft, you might notice that soap lathers more easily, and less detergent is needed for laundry and dishes. Over time, very soft water can be gentler on plumbing and appliances, potentially extending their lifespan by reducing mineral buildup. However, some people find the taste slightly different compared to harder water. Should you prefer a higher mineral content, a whole-house water conditioner could be considered, though it's not typically necessary for health or appliance protection with this water quality.
