Canton Water Hardness & Quality Report (2026)

The Canton Water Department serves approximately 70,000 residents in Stark County, Ohio. Water is sourced from three treatment plants utilizing a mix of groundwater and surface water: the West Branch Water Treatment Plant drawing from the West Branch of Nimishillen Creek and local aquifers, the Tuscarawas Water Treatment Plant sourcing from the Tuscarawas River, and the Hall of Fame Water Treatment Plant also tapping river influences. Treatment involves coagulation, sedimentation, filtration, disinfection with chlorine, and pH adjustment to ensure compliance with state and federal standards.

The watershed encompasses the Tuscarawas River basin within the larger Ohio River drainage, characterized by rolling glacial plains and underlying Paleozoic sedimentary rocks. Devonian shale and limestone formations, interspersed with Carboniferous sandstones, form the bedrock aquifer system. Glacial deposits from the Pleistocene Wisconsinan glaciation have shaped shallow unconfined aquifers, imparting a hard character through mineral dissolution from carbonate rocks. This geology results in naturally mineralized water with elevated calcium and magnesium, typical of the region's hard water supply.

Hard water promotes significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Soap and detergent performance diminishes, leading to higher usage and residue on dishes or skin. A water softener is strongly recommended for households, along with regular flushing of hot water systems and installing scale inhibitors. The Canton Water Department reports consistent compliance with EPA standards, including no lead or copper violations under the LCR; iron levels occasionally cause discoloration, addressed through aeration and filtration. pH is maintained around 7.5–8.5, and no PFAS exceedances are noted in recent Consumer Confidence Reports.
