Brunswick Water Hardness & Quality Report (2026)

Brunswick, Ohio, in Medina County — a major northeast Ohio suburban community between Akron and Cleveland (Brunswick is one of the most significant Medina County suburban communities — a major bedroom community in the I-71 corridor between Cleveland and Akron, representing the suburban expansion of northeast Ohio's two major metros), a rapidly growing Medina County community with significant residential development from the 1970s onward, a diverse Medina County community with a significant Appalachian heritage, Slovak-American, and Polish-American population, and a community in one of the most rapidly changing demographic corridors in northeast Ohio — draws its municipal water supply via the City of Brunswick Water Division. Water hardness in Brunswick measures 187 mg/L — classified as hard.

Brunswick's hard supply reflects the northeast Ohio Medina County geology. The supply at Brunswick–Medina County draws from: the Pennsylvanian Allegheny Group (calcareous-poor to moderate coal-bearing shale and sandstone); the Devonian–Mississippian Bedford Shale and Berea Sandstone (calcareous-moderate); and the Wisconsin Age calcareous Erie Lobe till (carbonate-rich calcareous glacial till with abundant limestone rock fragments — the dominant surface geology of Medina County). City of Brunswick treatment produces the hard 187 mg/L.

At 187 mg/L, Brunswick residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. City of Brunswick Water Division consistently delivers water meeting all Ohio EPA and federal EPA Safe Drinking Water Act requirements.
