What Makes Shakopee's Water Unique?
Local geology and source profile
Shakopee, Minnesota, the Scott County seat — a major south Twin Cities suburban community on the Minnesota River, home of Valleyfair Amusement Park (one of the largest amusement parks in the upper Midwest), the Canterbury Park horse racing venue, and the Mystic Lake Casino (one of the largest Native American casinos in the United States, owned by the Shakopee Mdewakanton Sioux Community — the community for whom Shakopee is named), a historically significant Dakota Sioux (Mdewakanton Dakota) community site — draws its municipal water supply from the Prairie du Chien–Jordan Aquifer via the City of Shakopee Water Division. Water hardness in Shakopee measures 120.5 mg/L — classified as moderately hard.
Shakopee's moderate hardness reflects the Scott County Paleozoic carbonate aquifer geology. The Prairie du Chien–Jordan Aquifer at Shakopee–Scott County draws from: the Ordovician Prairie du Chien Dolomite (highly calcareous dolomite of the Twin Cities artesian basin — the primary source aquifer); the Cambrian Jordan Sandstone (siliceous sandstone with calcareous cement). The aquifer is confined beneath calcareous Wisconsin Age glacial till, accumulating moderate dolomite hardness. City of Shakopee's treatment of the Prairie du Chien Dolomite water produces the moderate 120.5 mg/L.
At 120.5 mg/L, Shakopee residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. City of Shakopee Water Division consistently delivers water meeting all Minnesota MDH and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Prairie du Chien–Jordan Aquifer via the City of Shakopee Water Division — the Scott County Minnesota south Twin Cities suburban Minnesota River Valley (Ordovician calcareous Prairie du Chien Dolomite and Cambrian Jordan Sandstone — the Twin Cities Paleozoic carbonate sequence, with significant calcareous till cover); moderately hard supply at 120.5 mg/L in Scott County.
