What Makes Quartz Hill's Water Unique?
Local geology and source profile
Quartz Hill, California, in Los Angeles County — a Los Angeles County unincorporated community adjacent to Palmdale and Lancaster in the Antelope Valley — receives its water from Los Angeles County Waterworks District (LACWWD) or California Water Service, drawing from the Colorado River aqueduct and local groundwater through the south-central California distribution.
The moderately hard 91 mg/L hardness and TDS of 221.3 mg/L reflect the Antelope Valley supply's moderate character — the Precambrian San Gabriel Granite is largely insoluble, while Quaternary Antelope Valley alluvium contributes moderate calcareous mineral content, and the Colorado River aqueduct contributes additional dissolved minerals from its arid-region drainage (compare Palmdale CA: 88/215 in Los Angeles County comparable; Lancaster CA: 93/227 in Los Angeles County comparable; Quartz Hill consistent moderate from the same Los Angeles County Colorado River Antelope Valley granitic supply). The Antelope Valley supply — Precambrian San Gabriel Granite (insoluble — primary dilutant), Quaternary Antelope Valley alluvium (calcareous — primary hardness contributor), and Quaternary Colorado River alluvium (calcareous — TDS contributor).
At 91 mg/L with TDS 221, Quartz Hill's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 4.5 ppt is moderate — a certified drinking water filter provides added protection. Review LACWWD's annual water quality report.
Geology & Source: Quartz Hill in Los Angeles County draws from the LACWWD on the Colorado River supply (Los Angeles County, south California) — the Antelope Valley draws from Precambrian San Gabriel Granite (insoluble) and Quaternary Antelope Valley alluvium (calcareous) — California Los Angeles County Colorado River Antelope Valley granitic supply produces moderately hard water at 91 mg/L with TDS 221.3 mg/L.
