What Makes Mounds View's Water Unique?
Local geology and source profile
Mounds View, Minnesota, in Ramsey County — a Ramsey County city adjacent to Roseville and New Brighton in the north Minneapolis-St. Paul metro — receives its water from the Mounds View Water system, drawing from the Mississippi River or local Prairie du Chien aquifer (Ramsey County) through the north Twin Cities distribution.
The very hard 262 mg/L hardness and TDS of 666.9 mg/L reflect the north Twin Cities Ramsey County supply's very hard dolomitic character — the Ordovician Prairie du Chien Dolomite aquifer across Ramsey County produces extremely hard water consistent with the Minneapolis-St. Paul metro communities (compare Waunakee WI: 233.5/728.8; Vadnais Heights MN: ~230 mg/L on the same Ramsey County Prairie du Chien draw; Mounds View among the harder northern Ramsey County cities). The Prairie du Chien aquifer at Ramsey 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 262 mg/L with TDS 667, Mounds View's 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 7.2 ppt warrants a certified drinking water filter — the Ramsey County north Twin Cities industrial corridor contribute to Mounds View's elevated readings.
Geology & Source: Mounds View in Ramsey County draws from the Mounds View Water on the Prairie du Chien aquifer (Ramsey County, north Minneapolis-St. Paul metro, Minnesota) — the Prairie du Chien aquifer at Ramsey County is developed in Ordovician Prairie du Chien Dolomite (dolomitic) and Cambrian Jordan Sandstone (insoluble) — Minnesota Ramsey County Prairie du Chien Ordovician dolomitic aquifer produces very hard water at 262 mg/L with TDS 666.9 mg/L.
