What Makes Westlake's Water Unique?
Local geology and source profile
Westlake, Ohio, in Cuyahoga County — a major west Cleveland suburban community (Westlake is one of the premier west Cleveland suburbs — an affluent Cuyahoga County community with high household incomes, excellent public schools, and a significant commercial and corporate presence along the Detroit Road–Crocker Road corridor), home of a significant corporate and healthcare campus cluster (Westlake's Crocker Park — a large outdoor lifestyle shopping center and mixed-use development — is one of the most significant retail and commercial developments in the Cleveland metro), a diverse Cuyahoga County community with a significant professional and older suburban population, adjacent to Bay Village and Rocky River along the Lake Erie shoreline, and a community with strong civic amenities and parks — draws its municipal water supply from Lake Erie via the Westlake Water Division. Water hardness in Westlake measures 165.5 mg/L — classified as hard.
Westlake's hard supply reflects the Cuyahoga County Lake Erie supply's calcareous character. The Lake Erie supply at Westlake–Cuyahoga County is influenced by the Devonian Ohio Shale and Silurian Niagaran Dolomite watershed geology. Westlake Water Division distributes Lake Erie supply (with treatment) to the west Cleveland suburban zone, producing the hard 165.5 mg/L.
At 165.5 mg/L, Westlake residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. Westlake Water Division consistently delivers water meeting all Ohio EPA and EPA Safe Drinking Water Act requirements.
Geology & Source: Lake supply from Lake Erie via the Westlake Water Division or Cuyahoga County water system — the Cuyahoga County west Cleveland suburban Westlake corridor (Devonian calcareous Ohio Shale and Silurian Niagaran Dolomite — the highly calcareous northeast Ohio Paleozoic carbonate; Cuyahoga County Lake Erie supply with treatment to Westlake west Cleveland zone); hard supply at 165.5 mg/L in Cuyahoga County.
