Maple Heights Water Hardness & Quality Report (2026)

Maple Heights, Ohio, in Cuyahoga County in the southeast Cleveland metropolitan area — a working-class suburban community adjacent to Garfield Heights and Shaker Heights — receives its municipal water from the City of Maple Heights Water Division or through purchase from the Cleveland Division of Water, which draws from the Cuyahoga River or Lake Erie through the regional Northeast Ohio distribution system. Maple Heights is served through Cuyahoga County's southeastern distribution network.

The very hard 213 mg/L hardness and elevated TDS of 500.2 mg/L are notably harder than the Cleveland city core's Lake Erie supply (~145–165 mg/L), reflecting higher Cuyahoga River carbonate input in the southeast Cuyahoga County service zone. The Cuyahoga River drains the Devonian Columbus Limestone and Delaware Limestone of northeast Ohio — ancient Devonian marine carbonates with prolific spring baseflow from the carbonate aquifer sustaining consistently high calcium and magnesium bicarbonate concentrations. The southeast Cleveland suburbs in the Cuyahoga River service zone receive harder water than the direct Lake Erie intake zones because the Cuyahoga's carbonate baseflow significantly adds to the blended distribution hardness.

At 213 mg/L, Maple Heights residents face very hard water — consistent with the southeast Cuyahoga County suburban supply. Scale builds rapidly in kettles and coffee machines within weeks, dishwashers require rinse aid or softener treatment, and bathroom fixtures develop persistent calcium deposits. Descaling appliances every four to six weeks is the appropriate cadence. A whole-house water softener is strongly recommended for Cuyahoga County homes at this hardness level. The PFAS level of 8.4 ppt warrants a certified drinking water filter — the Cuyahoga River's industrial legacy (the infamous 1969 river fire) and the southeast Cleveland industrial corridor contribute substantially to PFAS levels in the southeast Cuyahoga supply zone.
