What Makes Rogers's Water Unique?
Local geology and source profile
Rogers, Minnesota, in Hennepin County — a Hennepin County city adjacent to Elk River and Dayton in the northwest Twin Cities metro — receives its water from the City of Rogers Water, drawing from the Mississippi River or Prairie du Chien aquifer (Hennepin County) through the northwest Twin Cities distribution.
The very hard 268.5 mg/L hardness and TDS of 692.8 mg/L reflect the northwest Twin Cities Hennepin County supply's very hard dolomitic character — the Ordovician Prairie du Chien Dolomite aquifer produces very hard water throughout the Twin Cities metro (compare Mounds View MN: 262/667 in Ramsey County on the same Prairie du Chien supply; Rogers comparable on the Hennepin County northwest metro draw). The Prairie du Chien aquifer at Hennepin County — Ordovician Prairie du Chien Dolomite (dolomitic — primary hardness contributor), Ordovician Oneota Dolomite (dolomitic — secondary contributor), and Cambrian Jordan Sandstone (insoluble — dilutant at base).
At 268.5 mg/L with TDS 693, Rogers' water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 7.3 ppt warrants a certified drinking water filter — the Hennepin County northwest Twin Cities industrial corridor contribute to Rogers' elevated readings.
Geology & Source: Rogers in Hennepin County draws from the City of Rogers Water on the Prairie du Chien aquifer (Hennepin County, northwest Twin Cities metro, Minnesota) — the Prairie du Chien aquifer at Hennepin County is developed in Ordovician Prairie du Chien Dolomite (dolomitic) and Cambrian Jordan Sandstone (insoluble) — Minnesota Hennepin County Prairie du Chien Ordovician dolomitic aquifer produces very hard water at 268.5 mg/L with TDS 692.8 mg/L.
