What Makes Live Oak's Water Unique?
Local geology and source profile
Live Oak, California, in Santa Cruz County — an unincorporated Santa Cruz County community adjacent to Santa Cruz and Capitola on the north Monterey Bay coast — receives its municipal water from the Soquel Creek Water District or Santa Cruz Water Department, drawing from Soquel Creek basin wells and Loch Lomond Reservoir (Santa Cruz Mountains) through the local water system.
The moderately soft 85.5 mg/L hardness and TDS of 207.2 mg/L reflect the Santa Cruz Mountains mixed supply character. The Soquel Creek basin draws from Quaternary alluvial fill (Soquel Valley), Cretaceous Santa Cruz Mudstone (slightly calcareous — minor hardness), and the Jurassic Franciscan Complex (insoluble mafic melange — primary softness contributor in the Santa Cruz Mountains). The small coastal watershed produces the moderately soft supply.
At 85.5 mg/L, Live Oak's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 4.5 ppt warrants a certified drinking water filter — the Monterey Bay coastal PFAS background, the Santa Cruz County urban runoff, and the northern Monterey Bay suburban PFAS complex contribute to Live Oak's readings.
Geology & Source: Live Oak in Santa Cruz County draws from the Soquel Creek Water District on the Soquel Creek wells (Santa Cruz County) — the aquifer draws from Quaternary alluvium over Cretaceous Santa Cruz Mudstone and Jurassic Franciscan Complex — California Santa Cruz County alluvial-Franciscan supply produces moderately soft water at 85.5 mg/L with TDS 207.2 mg/L in this Santa Cruz County community.
