Where Pataskala's Water Comes From
Pataskala is served by the City of Pataskala water system, drawing from Licking County groundwater sources. The city has grown rapidly as a Columbus exurb, with significant new construction. Pataskala's Licking County limestone geology produces very hard water — among the hardest in the Columbus metro.
Pataskala Water: Licking County Limestone at the Columbus Exurban Edge
Pataskala sits in western Licking County where the limestone and dolomite formations are thick and calcium-rich. The city's groundwater draws from the Licking County limestone aquifer, producing 15–18 gpg hardness — comparable to Powell and Lewis Center in Delaware County. Pataskala's rapid growth as a Columbus exurb has brought significant new construction, with modern appliances that residents expect to last — but hard water shortens that lifespan dramatically without treatment.
