What Makes Roseville's Water Unique?
Local geology and source profile
Roseville, Minnesota, in Ramsey County — a major north suburban St. Paul community (Roseville is the most populous city in Ramsey County outside of St. Paul — a first-ring north suburban community directly adjacent to St. Paul and Minneapolis), home of Rosedale Center (a major Twin Cities regional shopping mall), home of the former Har Mar Mall and a major commercial corridor along Snelling Avenue (the Roseville–Arden Hills commercial strip is one of the most economically significant suburban corridors in Ramsey County), and a diverse Ramsey County community with a significant Vietnamese-American, Hmong-American, and Korean-American population — draws its municipal water supply from the deep Prairie du Chien–Jordan aquifer via the City of Roseville Water Division. Water hardness in Roseville measures 284 mg/L — classified as very hard.
Roseville's very hard supply reflects the Ramsey County Paleozoic carbonate aquifer's highly calcareous character. The Prairie du Chien Dolomite and Jordan Sandstone at Roseville–Ramsey County draws from: the Ordovician Prairie du Chien Group Dolomite (highly calcareous dolomite — the primary Twin Cities deep aquifer carbonate); the Cambrian Jordan Sandstone (calcareous-moderate deep aquifer); and the Ordovician St. Peter Sandstone (calcareous-moderate). City of Roseville applies minimal softening, producing the very hard 284 mg/L — one of the hardest municipal supplies in the Twin Cities metro.
At 284 mg/L, Roseville residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. City of Roseville Water Division consistently delivers water meeting all Minnesota PCA and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Jordan Sandstone and Prairie du Chien Dolomite Aquifer via the City of Roseville Water Division (Ramsey County) — the Ramsey County north suburban St. Paul corridor (Ordovician Prairie du Chien Dolomite and Cambrian Jordan Sandstone — the highly calcareous Minnesota Twin Cities Paleozoic carbonate aquifer; Roseville north Ramsey distribution zone); very hard supply at 284 mg/L in Ramsey County.
