What Makes North Royalton's Water Unique?
Local geology and source profile
North Royalton, Ohio, in Cuyahoga County — a major southwest Cleveland suburban community (North Royalton is a significant Cuyahoga County city — a southwest Cleveland suburb in the outer Cuyahoga County ring; North Royalton is known as a primarily family-oriented suburban community with a strong community identity, excellent public schools, and significant residential development since the post-WWII era), a diverse Cuyahoga County community with a primarily working-class, Slavic-American (Czech-American, Slovak-American, Polish-American), and suburban family population, adjacent to Broadview Heights and Brecksville in the southwest Cuyahoga County corridor, home of North Royalton City School District (one of the consistently high-performing school districts in southwest Cuyahoga County), and one of the southwest Cleveland suburban communities — draws its municipal water supply from Lake Erie via the Cleveland Division of Water. Water hardness in North Royalton measures 246 mg/L — classified as very hard.
North Royalton's very hard supply reflects the southwest Cleveland CDW distribution zone's limited softening. The Cleveland Division of Water distributes Lake Erie supply through the southwest Cuyahoga County North Royalton zone with limited softening, producing the very hard 246 mg/L.
At 246 mg/L, North Royalton residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. Cleveland Division of Water consistently delivers water meeting all Ohio EPA and EPA Safe Drinking Water Act requirements.
Geology & Source: Lake supply from the Lake Erie via the Cleveland Division of Water (CDW) — the Cuyahoga County southwest Cleveland suburban North Royalton corridor (Devonian calcareous Ohio Shale and Devonian calcareous-moderate Berea Sandstone — the calcareous southwest Cleveland CDW distribution to North Royalton; limited softening); very hard supply at 246 mg/L in Cuyahoga County.
