Strongsville Water Hardness & Quality Report (2026)

Strongsville, Ohio, in Cuyahoga County south of Cleveland — a major Cleveland south suburban community, one of Cuyahoga County's largest suburban cities, a premier south Cleveland suburb known for SouthPark Mall (one of northern Ohio's largest shopping centers), the Strongsville Performing Arts Center, and a community with strong Slovak-American and Italian-American heritage — draws its municipal water supply from Lake Erie via the Cleveland Water Division, distributed to Strongsville. Water hardness in Strongsville measures 122 mg/L — classified as moderately hard.

Strongsville's moderate hardness — softer than inner Cleveland suburban zones — reflects the South Cleveland suburban distribution characteristics. Strongsville is one of Cuyahoga County's more distant south suburbs (approximately 15 miles from downtown Cleveland). The Cleveland Water Division distribution in the Strongsville zone includes moderately aged infrastructure from the 1960s–1990s Strongsville suburban buildout era — newer overall than the inner Cleveland suburbs, with a mix of cast-iron and ductile-iron mains. The newer infrastructure in the Strongsville zone accumulates less mineral content than the older inner suburb zones, producing the moderate 122 mg/L.

At 122 mg/L, Strongsville residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. City of Strongsville Water Division consistently delivers water meeting all Ohio EPA and federal EPA Safe Drinking Water Act requirements.
