What Makes Kingsburg's Water Unique?
Local geology and source profile
Kingsburg, California, in Fresno County — a Fresno County city adjacent to Selma and Reedley on the Kings River in the San Joaquin Valley of central California — receives its water from the City of Kingsburg Water system or a local district, drawing from the Kings River and supplemental San Joaquin Valley groundwater through the central California distribution.
The hard 169.5 mg/L hardness and elevated TDS of 511.4 mg/L reflect the Fresno County Kings River supply's hard character with additional dissolved solids — the Kings River originates in Sierra Nevada granodiorite (insoluble), but valley blending with Kings River Terrace alluvium and Kings River groundwater adds sulfates, chlorides, and bicarbonates characteristic of the arid San Joaquin Valley (compare Selma CA: 166/504 in Fresno County comparable; Reedley CA: 172/518 in Fresno County comparable; Kingsburg consistent hard from the same Fresno County Kings River Sierra Nevada calcareous supply). The Kings River at Fresno County — Cretaceous Sierra Nevada Granodiorite (insoluble — dilutant), Tertiary Kern River Formation (slightly calcareous — primary hardness contributor), and Quaternary San Joaquin Valley alluvium (calcareous — TDS contributor).
At 169.5 mg/L with TDS 511, Kingsburg's water is hard with elevated TDS — scale builds in appliances over months. Quarterly descaling is appropriate. The PFAS level of 6.9 ppt warrants a certified drinking water filter. Review the City of Kingsburg's annual water quality report for the latest contaminant data.
Geology & Source: Kingsburg in Fresno County draws from the Kingsburg Water on the Kings River (Fresno County, central California) — the Kings River at Fresno County drains Cretaceous Sierra Nevada Granodiorite (insoluble) and Tertiary Kern River Formation (slightly calcareous) — California Fresno County Kings River Sierra Nevada calcareous supply produces hard water at 169.5 mg/L with TDS 511.4 mg/L.
