What Makes North Saint Paul's Water Unique?
Local geology and source profile
North Saint Paul, Minnesota, in Ramsey County — a Ramsey County city adjacent to Maplewood and Little Canada in the northeast Saint Paul suburbs — receives its water from the Saint Paul Regional Water Services, drawing from the Mississippi River through the east-central Minnesota distribution.
The hard 148 mg/L hardness and TDS of 282.7 mg/L reflect the Ramsey County Mississippi River supply's hard character — the Precambrian Canadian Shield provides insoluble granitic dilution, while Ordovician Prairie du Chien Dolomite and Cambrian Jordan Sandstone contribute dolomitic mineral content from the Mississippi headwaters limestone belt (compare Maplewood MN: 145/276 in Ramsey County comparable; Little Canada MN: 151/289 in Ramsey County comparable; North Saint Paul consistent hard from the same Ramsey County Mississippi River Precambrian-Ordovician supply). The Mississippi watershed at Ramsey County — Precambrian Canadian Shield (insoluble — primary dilutant), Ordovician Prairie du Chien Dolomite (dolomitic — primary hardness contributor), and Cambrian Jordan Sandstone (slightly calcareous — minor TDS).
At 148 mg/L with TDS 283, North Saint Paul's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 4.6 ppt is moderate — a certified drinking water filter provides added protection. Review Saint Paul Regional Water Services' annual water quality report.
