Saint Romuald Water Hardness & Quality Report (2026)

Ville de Lévis supplies Saint-Romuald with water drawn directly from the St. Lawrence River. This major waterway, forming the estuary near Quebec City, is the primary source, with contributions from the Chaudière River. The Lévis municipal treatment facilities manage the purification process for the Chaudière-Appalaches region's south shore communities, including Saint-Romuald. While specific plant names aren't provided, the distribution network ensures potable water meeting federal standards reaches all residents.

The watershed's geology is dominated by Paleozoic sedimentary bedrock, specifically Ordovician limestones and shales, part of the Appalachian foreland basin. These carbonate-rich formations readily dissolve calcium and magnesium ions as the St. Lawrence River flows through. Further mineral contributions come from the Chaudière River, which drains Appalachian metamorphic and igneous terrains. Though glacial till and marine clays overlay the bedrock, they only partially moderate the mineral pickup, resulting in a moderately mineralised supply.

Homeowners might notice a moderate buildup of limescale in appliances like water heaters and coffee makers, which can affect their efficiency. You'll likely find that soaps and detergents require a bit more product to lather effectively. While regular descaling with vinegar can manage this, installing a water softener is typically optional but can extend appliance life and improve sudsing. The water's pH is a neutral 7.6, and lead levels are well below federal action limits.
