What Makes Anoka's Water Unique?
Local geology and source profile
Anoka, Minnesota, in Anoka County — the Anoka County seat adjacent to Coon Rapids and Fridley on the Mississippi River at the mouth of the Rum River in the north Minneapolis metro — receives its municipal water from the Anoka Water Division, drawing from the Mississippi River at the Anoka intake (Anoka County).
The moderately hard 155.5 mg/L hardness and TDS of 303.2 mg/L are softer than the Minneapolis-Hopkins downstream reading (265 mg/L), as the Mississippi at Anoka is upstream of the Twin Cities and receives less carbonate loading from the Minnesota Drift Plain. The Mississippi at Anoka drains the central Minnesota uplands — Ordovician Prairie du Chien dolomite (carbonate aquifer recharge), Cretaceous Greenhorn calcareous shale, and calcareous Pleistocene Des Moines Lobe till.
At 155.5 mg/L, Anoka's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 4.7 ppt warrants a certified drinking water filter — the Anoka County Minneapolis metro suburban corridor, the upper Mississippi PFAS input, and the north Minnesota PFAS background contribute to Anoka's readings.
Geology & Source: Anoka in Anoka County draws from the Anoka Water Division on the Mississippi River (Anoka County, north Minneapolis metro) — the Mississippi at Anoka drains the Minnesota Drift Plain (Ordovician Prairie du Chien dolomite, calcareous Pleistocene Des Moines Lobe till) — Minnesota Anoka County Mississippi River Ordovician dolomite watershed produces moderately hard water at 155.5 mg/L with TDS 303.2 mg/L in this Anoka County Minnesota city.
