Perrysburg Water Hardness & Quality Report (2026)

Perrysburg, Ohio, in Wood County — the Wood County seat south of Toledo on the Maumee River, site of the Battle of Fallen Timbers (1794), a rapidly growing Toledo suburban community known for the Levis Commons lifestyle center and the strong Wood County school district — receives its municipal water from the Perrysburg Water Treatment Plant, which draws from the Maumee River at the Perrysburg reach. The Maumee River is the primary drinking water source for the Toledo metropolitan area's Wood County communities.

The moderately hard 185 mg/L hardness and TDS of 395.9 mg/L reflect the Maumee River watershed's northwest Ohio carbonate geology. The Maumee River drains the Great Black Swamp — the former vast wetland of northwest Ohio — a flat lacustrine plain underlain by the Silurian Niagara Dolomite platform (the same ancient reef dolomite responsible for hard water throughout the Great Lakes dolomite plain) and the Devonian Sylvania Sandstone carbonate formation. The Maumee watershed's extensive agricultural tile drain network releases dissolved minerals from calcareous glacial till soils, and the dolomite bedrock provides continuous carbonate input to the river. Perrysburg's Maumee River supply reflects this consistently moderately hard northwest Ohio carbonate character.

At 185 mg/L, Perrysburg's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and bathroom fixtures develop calcium deposits. Quarterly descaling of heating appliances is the standard schedule. The PFAS level of 7.2 ppt warrants a certified drinking water filter — the Maumee River watershed's extensive agricultural drainage (legacy agricultural PFAS products), the Toledo industrial corridor, and the northwest Ohio manufacturing and logistics belt contribute to Wood County's PFAS background.
