What Makes Palos Verdes Estates's Water Unique?
Local geology and source profile
Palos Verdes Estates, California, in Los Angeles County — a Los Angeles County city adjacent to Rancho Palos Verdes and Rolling Hills on the Palos Verdes Peninsula in south California — receives its water from Palos Verdes Water or California Water Service, drawing from the Metropolitan Water District (Los Angeles County) through the south California distribution.
The moderately hard 132.5 mg/L hardness and TDS of 362.3 mg/L (TDS elevated relative to hardness — reflecting the MWD Colorado River-SWP blended supply's dissolved solids from the Colorado River evaporitic content) reflect the south California Los Angeles County MWD supply's moderate calcareous character. The MWD blended supply at Los Angeles County — Colorado River (calcareous-evaporitic — primary hardness and TDS contributor), State Water Project Northern California (very soft — dilutant), and local Los Angeles County distribution system dissolution (minor TDS contributor).
At 132.5 mg/L, Palos Verdes Estates' water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.7 ppt warrants a certified drinking water filter — Los Angeles Air Force Base (Los Angeles County — AFFF) and the south California Los Angeles County industrial corridor contribute to Palos Verdes Estates' readings.
Geology & Source: Palos Verdes Estates in Los Angeles County draws from the Palos Verdes Water or California Water Service on the Colorado River via Metropolitan Water District or State Water Project (Los Angeles County, south California) — the MWD supply blends Colorado River (calcareous) and SWP (soft) — California Los Angeles County MWD Colorado River-SWP blended supply produces moderately hard water at 132.5 mg/L with TDS 362.3 mg/L.
