What Makes Citrus's Water Unique?
Local geology and source profile
Citrus, California, in Los Angeles County — a Los Angeles County unincorporated community adjacent to Azusa and San Dimas in the San Gabriel foothills — receives its water from Golden State Water or San Gabriel Valley Municipal Water District (SGVMWD), drawing from the San Gabriel River and local groundwater through the south-central California distribution.
The hard 167 mg/L hardness and TDS of 498 mg/L reflect the Los Angeles County San Gabriel supply's hard calcareous character — the Jurassic San Gabriel Granodiorite is largely insoluble, while Quaternary San Gabriel Valley alluvium concentrates calcareous mineral content from the San Gabriel Mountains drainage, and the Colorado River imported water supply contributes additional dissolved minerals (compare Azusa CA: 164/490 in Los Angeles County comparable; San Dimas CA: 169/506 in Los Angeles County comparable; Citrus consistent hard from the same Los Angeles County San Gabriel River granodiorite supply). The San Gabriel watershed — Jurassic San Gabriel Granodiorite (insoluble — primary dilutant), Quaternary San Gabriel Valley alluvium (highly calcareous — primary hardness contributor), and Quaternary Colorado River alluvium (calcareous — TDS contributor).
At 167 mg/L with TDS 498, Citrus' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.7 ppt warrants a certified drinking water filter. Review Golden State Water's annual water quality report.
Geology & Source: Citrus in Los Angeles County draws from the Golden State Water on the San Gabriel River supply (Los Angeles County, south California) — the San Gabriel watershed draws from Jurassic San Gabriel Granodiorite (insoluble) and Quaternary San Gabriel Valley alluvium (highly calcareous) — California Los Angeles County San Gabriel River granodiorite supply produces hard water at 167 mg/L with TDS 498 mg/L.

Data Sources & Methodology
Water quality data for Citrus is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
