West Henrietta Water Hardness & Quality Report (2026)

Residents of West Henrietta, New York, receive their drinking water from the Town of Henrietta Water Department. Their primary sources have been Hemlock and Canadice Lakes since 1876. This supply is augmented by water purchased from the Monroe County Water Authority, which draws from Lake Ontario and treats it at the Shoremont Treatment Plant on Dewey Avenue in Rochester. The Town of Henrietta Water Department serves both residential and commercial customers in this Monroe County suburb, west of Rochester. The watershed supplying Hemlock and Canadice Lakes is located in the southern Finger Lakes region, with streams feeding these reservoirs draining Devonian limestone and shale bedrock characteristic of the Appalachian Basin. Glacial till covers these bedrock formations, influencing the chemistry of surface runoff. Water drawn from Lake Ontario interacts with Silurian dolomites and shales within the larger Great Lakes basin.

This geological makeup results in a hard water supply. As water flows through Devonian limestone and Silurian dolomite formations, it dissolves calcium and magnesium ions. The prevalence of karst features within the Appalachian Basin bedrock further enhances this mineral pickup. This process naturally mineralizes the water, creating a profile typical of the region's hydrology, which is influenced by glacial deposits and bedrock interactions. The Monroe County Water Authority's Lake Ontario supply also picks up minerals from its surrounding geological environment, reinforcing the hard water characteristics observed in the West Henrietta service area.

Homeowners in West Henrietta may notice the effects of hard water on their appliances and plumbing. Scale buildup is common in pipes, water heaters, and dishwashers, which can reduce efficiency and shorten their lifespan. You might also observe soap scum in bathrooms and on dishes after washing. To combat these issues, regular descaling of appliances with vinegar is recommended, along with annual checks of water heater elements. Installing a water softener is often advised to protect your plumbing and reduce the frequency of these maintenance tasks. While the EPA sets legal standards for drinking water, analyses have detected contaminants like radium and trihalomethanes above health guidelines, though they are colorless and tasteless. Treatment processes at the Shoremont and local plants include filtration, disinfection with chlorination, and fluoridation to ensure safety.
