What Makes Avenal's Water Unique?
Local geology and source profile
Avenal, California, in Kings County — a Kings County city adjacent to Coalinga and Huron in the west San Joaquin Valley — receives its water from the City of Avenal Water, drawing from the State Water Project (Kings County) through the central California San Joaquin Valley distribution.
The moderately soft 43 mg/L hardness and TDS of 90.2 mg/L reflect the central California Kings County SWP supply's soft character — driven by the Sierra Nevada snowmelt insoluble granodiorite runoff that is the primary source for the SWP Northern California component, producing the characteristic soft water of the Central Valley SWP supply cities that receive primarily Northern California water (compare Discovery Bay CA: 29 mg/L on the purer Delta supply; Avenal slightly harder from the blended SWP delivery). The Kings County SWP supply — Jurassic Sierra Nevada granodiorite (insoluble — primary dilutant via SWP), Quaternary Delta alluvium (slightly calcareous — trace contributor), and limited Coast Range calcareous input (slightly calcareous — minor contributor).
At 43 mg/L, Avenal's water is moderately soft — light scale forms very slowly in appliances, dishwashers remain efficient, and no softening is needed. Annual descaling is appropriate. The PFAS level of 3.2 ppt warrants a certified drinking water filter — the Kings County central California agricultural-industrial corridor contribute to Avenal's readings.
Geology & Source: Avenal in Kings County draws from the City of Avenal Water on the State Water Project (Kings County, central California San Joaquin Valley) — the SWP at Kings County delivers Sierra Nevada (Jurassic granodiorite — insoluble) snowmelt with minor calcareous delta sediment input — California Kings County State Water Project Sierra Nevada Jurassic-Quaternary insoluble supply produces moderately soft water at 43 mg/L with TDS 90.2 mg/L.
