What Makes Massillon's Water Unique?
Local geology and source profile
Massillon, Ohio, in Stark County — a major northeast Ohio industrial city (Massillon is one of Stark County's most historically significant cities — famous as a football powerhouse (Massillon Washington High School is the most celebrated high school football program in Ohio history, with more state championships than any other Ohio school); Massillon was a major steel and industrial city in the early 20th century), home of the Paul Brown Tiger Stadium (named for Paul Brown — the legendary football coach who was born in Norwalk, Ohio and coached at Massillon before going on to found the Cleveland Browns and Cincinnati Bengals NFL franchises), a diverse Stark County community with a primarily working-class heritage, adjacent to Canton (the NFL Hall of Fame city) in the Stark County metro, and a city in the post-industrial Ohio Rust Belt — draws its municipal water supply from the Tuscarawas River via the City of Massillon Water Division. Water hardness in Massillon measures 231 mg/L — classified as very hard.
Massillon's very hard supply reflects the Stark County Tuscarawas River watershed's calcareous carboniferous geology. The Tuscarawas River watershed drains the Mississippian Maxville Limestone and Pennsylvanian Pottsville Formation (calcareous carbonate). City of Massillon applies limited treatment, producing the very hard 231 mg/L.
At 231 mg/L, Massillon residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. City of Massillon Water Division consistently delivers water meeting all Ohio EPA and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Tuscarawas River via the City of Massillon Water Division — the Stark County northeast Ohio Tuscarawas River corridor (Mississippian calcareous Maxville Limestone and Pennsylvanian calcareous-moderate Pottsville sandstone — the highly calcareous northeast Ohio carboniferous terrain; Stark County Tuscarawas River supply with limited softening); very hard supply at 231 mg/L in Stark County.
