Gates-North Gates Water Hardness & Quality Report (2026)

The Town of Gates Water Department supplies residents of Gates-North Gates, New York, primarily from Hemlock and Canadice Lakes, two of the Finger Lakes, a system in place since 1876. This supply is augmented by treated water purchased from the Monroe County Water Authority (MCWA), which draws from Lake Ontario via its Shoremont Treatment Plant on Dewey Avenue in Rochester. This combined surface water strategy serves about 30,000 people in Monroe County, a part of the Rochester metropolitan area, with watershed drainage extending through the Genesee Basin and the Great Lakes system.

The water's journey from these sources means it interacts with the region's underlying geology. Devonian-age sedimentary rocks, including limestones and shales found in the Appalachian Plateau, naturally contribute dissolved calcium and magnesium ions. This dissolution, along with mineral leaching through glacial till and bedrock fractures, gives the water a moderately mineralized character. Unlike waters from purely granitic areas, this supply carries a notable mineral content due to the carbonate-rich bedrock and glacial deposits common in this glaciated upstate New York terrain.

This moderately hard water can lead to noticeable scale buildup on fixtures like kettles and showerheads, potentially reducing the efficiency and lifespan of appliances such as dishwashers. You might also find that soap doesn't lather as easily, which can affect skin and hair. Simple steps like regular descaling with vinegar, using low-flow aerators, and choosing detergents designed for hard water can help manage these effects. For those concerned about appliance longevity or the feel of the water, installing a water softener is often recommended. The MCWA's treated water meets EPA standards, including controlled fluoride levels and minimal lead and copper. While Gates' supply has shown a few contaminants slightly above health guidelines, they remain below legal limits, and filtration is generally advised.
