Understanding East Gwillimbury's Water Source
East Gwillimbury draws its drinking water from a combination of local groundwater wells and surface water (Lake Ontario) supplied by York Region. Because municipal wells tap into deep limestone aquifers, East Gwillimbury's municipal water has high natural concentrations of calcium and magnesium, classifying it as Hard to Very Hard.
Hardness Ratings by Community
Water hardness is measured in parts per million (ppm) or grains per gallon (GPG). Any measurement above 120 ppm (7 GPG) is classified as hard water.
| Community / Sector | Hardness (ppm) | Hardness (GPG) | Water Softener Status |
|---|---|---|---|
| Mount Albert | 315 ppm | 18.4 GPG | Mandatory (Extremely Hard) |
| Sharon | 175 ppm | 10.2 GPG | Highly Recommended |
| Holland Landing | 175 ppm | 10.2 GPG | Highly Recommended |
| Queensville | 175 ppm | 10.2 GPG | Highly Recommended |
| Yonge & Green Lane Corridor | 170 ppm | 9.9 GPG | Highly Recommended |
How Hard Water Ruins Your Appliances
When hard water is heated, the minerals solidify into calcium carbonate scale. This scale accumulates on water heater elements, reducing efficiency by 20% and clogging pipe fixtures, forcing premature replacement of washing machines and dishwashers.
