What Makes Marysville's Water Unique?
Local geology and source profile
Marysville, California, in Yuba County — the Yuba County seat adjacent to Yuba City on the Yuba River in the Sacramento Valley — receives its water from the City of Marysville Water, drawing from the Yuba River or Feather River (Yuba County) through the Sacramento Valley distribution.
The hard 155.5 mg/L hardness and TDS of 455.7 mg/L are harder than expected for Sierra Nevada-fed rivers (typically softer) — reflecting Marysville's Sacramento Valley floor position where the Eocene Ione Formation slightly calcareous valley sediment contacts and Sacramento Valley evaporative concentration add significant hardness over the pure Sierra Nevada insoluble supply (compare Half Moon Bay CA: 114/356 in San Mateo County comparable; Marysville harder from the Sacramento Valley calcareous accumulation). The Yuba River at Yuba County — Cretaceous Sierra Nevada Batholith (insoluble — primary dilutant from mountains), Eocene Ione Formation (slightly calcareous — primary hardness contributor), and valley evaporative concentration (calcareous — TDS contributor).
At 155.5 mg/L with TDS 456, Marysville's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 6.5 ppt warrants a certified drinking water filter — the Yuba County Sacramento Valley agricultural and industrial corridor contribute to Marysville's elevated readings.
Geology & Source: Marysville in Yuba County is served by City of Marysville Water drawing from the Yuba River — the Yuba-Feather watershed drains Cretaceous Sierra Nevada Batholith (insoluble) and Eocene Ione Formation (slightly calcareous) — CA Yuba County Sacramento Valley Sierra Nevada supply produces hard water at 155.5 mg/L with TDS 455.7 mg/L.
