What Makes La Riviera's Water Unique?
Local geology and source profile
La Riviera, California, in Sacramento County — a Sacramento County unincorporated community adjacent to Rancho Cordova and Citrus Heights in the east Sacramento Valley — receives its water from Sacramento County Water Agency or Sacramento Utilities, drawing from the American River through the north-central California distribution.
The very soft 45.5 mg/L hardness and low TDS of 96.8 mg/L reflect the Sacramento County American River supply's very soft Sierra Nevada character — the Precambrian Sierra Nevada Granite is largely insoluble, and Sierra Nevada snowmelt dilutes mineral content as it flows through the Sacramento Valley (compare Rancho Cordova CA: 43/92 in Sacramento County comparable; Citrus Heights CA: 47/101 in Sacramento County comparable; La Riviera consistent very soft from the same Sacramento County American River Sierra Nevada insoluble supply). The American River watershed — Precambrian Sierra Nevada Granite (insoluble — primary dilutant), Quaternary Sacramento alluvium (slightly calcareous — primary hardness contributor), and Holocene American River alluvium (slightly calcareous — minor TDS).
At 45.5 mg/L with TDS 97, La Riviera's water is very soft — virtually no scale buildup. Soft water can be mildly corrosive — monitor for copper staining. The PFAS level of 3.3 ppt is low — a clean result for the Sacramento area. Review Sacramento Utilities' annual water quality report.
Geology & Source: La Riviera in Sacramento County draws from the Sacramento Utilities on the American River (Sacramento County, north California) — the American River draws from Precambrian Sierra Nevada Granite (insoluble) and Quaternary Sacramento alluvium (slightly calcareous) — California Sacramento County American River Sierra Nevada insoluble supply produces very soft water at 45.5 mg/L with TDS 96.8 mg/L.
