What Makes Maple Grove's Water Unique?
Local geology and source profile
Maple Grove, Minnesota, in northwest Hennepin County — one of the Twin Cities' fastest-growing suburbs, consistently ranked among the best places to live in Minnesota — draws its municipal water supply through the City of Maple Grove Utilities Water Division, sourcing from a blend of Minneapolis Water Works treated Mississippi River water (distributed through the western Hennepin County regional grid) and local City of Maple Grove groundwater wells accessing the Jordan Sandstone and Prairie du Chien Group aquifer system beneath northwest Hennepin County. Water hardness in Maple Grove measures 105.5 mg/L — classified as moderately hard.
Maple Grove's moderate hardness reflects the northwest Hennepin County water blend from Mississippi River and Jordan Sandstone groundwater. The Minneapolis Water Works Mississippi River supply accumulates moderate dissolved calcium from the upstream Cambrian and Ordovician carbonate terrain in the upper Minnesota River watershed. Local Maple Grove groundwater from the Jordan Sandstone (Upper Cambrian) and Prairie du Chien Group (Lower Ordovician — calcareous dolomite) contribute dissolved calcium and magnesium. Maple Grove's moderate 105.5 mg/L is consistent with neighboring Plymouth (128 mg/L) in the same northwest Hennepin supply zone.
At 105.5 mg/L, Maple Grove residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. City of Maple Grove Utilities and Minneapolis Water Works consistently deliver water meeting all Minnesota MDH and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Minneapolis Water Works (City of Minneapolis) Mississippi River water and local Hennepin County groundwater via the City of Maple Grove Utilities Water Division — the northwest Hennepin County suburban Chicago distribution zone and the Jordan Sandstone–Prairie du Chien Dolomite aquifer; moderately hard supply at 105.5 mg/L in Hennepin County.
