What Makes Red Bluff's Water Unique?
Local geology and source profile
Red Bluff, California, in Tehama County — the Tehama County seat adjacent to Corning and Redding on the Sacramento River in north California — receives its water from the Red Bluff Utilities District, drawing from the Sacramento River (Tehama County) through the north California distribution.
The hard 180 mg/L hardness and very high TDS of 560.8 mg/L (TDS elevated relative to hardness — reflecting the Sacramento River's accumulation of dissolved solids from the upper Sacramento Valley) reflect the north California Tehama County Sacramento River supply's hard calcareous character. The Sacramento River at Tehama County drains the Cascade Range and Klamath Mountains — Quaternary Lassen Volcanic (slightly calcareous), Cretaceous Klamath Mountains metasedimentary (calcareous — primary hardness contributor), Quaternary Trinity Alps metamorphic (slightly calcareous), and the upper Sacramento Valley Great Valley Sequence (calcareous).
At 180 mg/L with TDS 560, Red Bluff's water is hard with very high dissolved solids. A water softener is recommended and a reverse osmosis system for drinking water is advisable. The PFAS level of 7.3 ppt warrants a certified reverse osmosis drinking water filter — Beale Air Force Base (Yuba County — AFFF) and the north California Sacramento Valley corridor contribute to Red Bluff's elevated readings.
Geology & Source: Red Bluff in Tehama County draws from the Red Bluff District on the Sacramento River (Tehama County, north California) — the Sacramento at Tehama drains the Cascade Range (Quaternary Lassen volcanic — slightly calcareous) and Cretaceous Great Valley Sequence (calcareous) — California Tehama County Sacramento River Cascade-Great Valley calcareous watershed produces hard water at 180 mg/L with TDS 560.8 mg/L.
