Sylvania Water Hardness & Quality Report (2026)

The City of Sylvania Water Department serves approximately 21,618 residents in Sylvania, Lucas County, Ohio, and surrounding areas in northwest Ohio near the Michigan border. The utility purchases all surface water from the City of Toledo, drawn primarily from Lake Erie. Treatment occurs at Toledo's facilities using conventional filtration, pre-oxidation with chlorine, and disinfection via chlorine and chlorine dioxide before distribution through Sylvania's system. For inquiries, contact 419-885-8965; the 2024 Consumer Confidence Report is available from the City of Sylvania.

The supply originates in the Lake Erie watershed, part of North America's largest Great Lakes basin, with water impounded in Lake Erie overlying Silurian Bass Islands dolomite and Devonian Columbus limestone formations. Pleistocene Wisconsinan glacial drift covers the region, buffering direct rock–water interaction. This surface water character results in a soft supply, with low dissolved minerals acquired during minimal transit through low-carbonate lakebed sediments, contrasting with harder groundwater from Ohio's underlying carbonate aquifers.

At soft water levels, scale buildup is minimal, sparing appliances like water heaters, dishwashers, and washing machines from rapid mineral deposits. Soap and detergent efficiency is high. A water softener is not needed or recommended; instead, monitor for potential corrosion from low hardness and consider phosphate additives if pipes show wear. The 2024 Consumer Confidence Report details testing for over 15 contaminants, with 3 exceeding EPA health-based guidelines though all within legal MCLs. Treatment includes coagulation, sedimentation, filtration, and chlorination; surface water sources require ongoing monitoring for disinfection byproducts and microbes.
