What Makes Canton's Water Unique?
Local geology and source profile
Canton, Ohio, the Stark County seat — home of the Pro Football Hall of Fame and the McKinley Presidential Library — draws its municipal water supply from the West Branch Tuscarawas River reservoir system (including the Sippo Lake and reservoir network in western Stark County) via the City of Canton Public Utilities Department Water Division, treating West Branch Tuscarawas water at the Canton Water Treatment Plant. The West Branch Tuscarawas River drains the northeastern Ohio Allegheny Plateau. Water hardness in Canton measures 233 mg/L — classified as very hard.
Canton's very hard supply reflects the northeastern Ohio Allegheny Plateau's geology in Stark County. The West Branch Tuscarawas watershed drains: the Devonian Ohio Shale and Columbus Limestone (calcareous black shale and limestone — significant carbonate contribution); the Mississippian Berea Sandstone (a siliceous sandstone, minor calcium contribution); the Cuyahoga Formation (Devonian–Mississippian calcareous shale and siltstone); and the Quaternary calcareous glacial till of the northeastern Ohio glacial plain (Laurentide Ice Sheet–derived calcareous drift). The calcareous Ohio Shale and glacial till combination in Stark County produces the very hard supply characteristic of the Tuscarawas–Massillon–Canton water district zone.
At 233 mg/L, Canton residents face significant hard water challenges. Scale deposits form rapidly on faucet aerators, showerheads, shower glass, and tile — monthly descaling with citric acid solution is essential maintenance. City of Canton Public Utilities Water Division consistently delivers water meeting all Ohio EPA and federal EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from Meyers Lake (Nimisila Reservoir watershed, West Branch Tuscarawas River) via the City of Canton Public Utilities Department Water Division — the Northeastern Ohio Allegheny Plateau Mississippian Berea Sandstone, Cuyahoga Shale, and Devonian Ohio Shale of Stark County; very hard supply at 233 mg/L in Stark County.
