What Makes Hudson's Water Unique?
Local geology and source profile
Hudson, Ohio, in Summit County — one of Northeast Ohio's most affluent and historically preserved communities, known for its exceptional Western Reserve architecture, Hudson Green historic district, and top-ranked schools — receives its municipal water from the City of Hudson Water Division or through purchase from the Summit County regional system, which draws from the Cuyahoga River corridor supply. Hudson is served through the Summit County northeastern distribution network.
The moderately hard 147.5 mg/L hardness and TDS of 273.7 mg/L reflect the Cuyahoga River basin's carbonate character in the Summit County reach. The Cuyahoga River and its Summit County tributaries drain the Devonian Columbus Limestone and Delaware Limestone of northeast Ohio — ancient marine carbonate formations providing consistent spring-fed carbonate baseflow to the river system throughout the year. The Cuyahoga's upper-basin carbonate aquifer sustains moderate hardness in the Summit County supply zone, producing water that is harder than expected for a river drawing from forested northeastern Ohio terrain but consistent with the regional Devonian carbonate platform geology.
At 147.5 mg/L, Hudson's water is moderately hard — a typical Summit County supply profile. Scale builds in kettles and coffee machines over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling of heating appliances is the standard schedule. The PFAS level of 5.7 ppt warrants a certified drinking water filter — the Cuyahoga River corridor's industrial manufacturing heritage (rubber and polymer industry in Akron, steel manufacturing in the lower Cuyahoga Valley) and the northeast Ohio industrial supply chain legacy contribute to PFAS levels in the Summit County regional water supply.
Geology & Source: Hudson in Summit County draws from the Akron-area regional water system or Summit County supply treating the Cuyahoga River — the upper Cuyahoga drains the Devonian carbonate platform (Columbus Limestone, Berea Sandstone) of northeast Ohio with spring carbonate baseflow — Devonian limestone drainage produces moderately hard water at 147.5 mg/L with TDS 274 mg/L in this affluent Summit County community.
