What Makes Linda's Water Unique?
Local geology and source profile
Linda, California, in Yuba County — an unincorporated Yuba County community adjacent to Marysville and Olivehurst in the northern Sacramento Valley — receives its municipal water from the Linda County Water District or Yuba County Water Agency, drawing from the Yuba River at the Yuba County intake, fed by New Bullards Bar Reservoir (Yuba County).
The extremely soft 36 mg/L hardness and very low TDS of 74.1 mg/L reflect the northern Sierra Nevada's insoluble crystalline watershed. The Yuba River drains the northern Sierra Nevada foothills and mountains — Jurassic Smartville Complex ophiolite (dark mafic volcanic rock — insoluble), Cretaceous Sierra Nevada Batholith granodiorite (insoluble granite), and Pleistocene glacial outwash (pure silica). The essentially insoluble Sierra Nevada crystalline geology produces the near-distilled soft water characteristic of all northern California Sierra Nevada supplies.
At 36 mg/L, Linda's water is extremely soft — no scale ever forms, soap lathers maximally, and appliances achieve maximum lifespan. No descaling is needed. The PFAS level of 3.0 ppt warrants a certified drinking water filter — Beale Air Force Base (Yuba County — AFFF, one of the closest major PFAS sources to the Yuba River watershed), and the northern Sacramento Valley PFAS background contribute to Linda's readings.
Geology & Source: Linda in Yuba County draws from the Linda County Water District on the Yuba River (Yuba County, northern California) — the Yuba drains the Sierra Nevada (Jurassic Smartville Complex ophiolite, Cretaceous Sierra Nevada Batholith granodiorite) — California Sierra Nevada granitic-ophiolite insoluble watershed produces extremely soft water at 36 mg/L with very low TDS 74.1 mg/L in this Yuba County California community.
