What Makes Valencia's Water Unique?
Local geology and source profile
Valencia, California is served by Valencia Heights Water Company, operating in the Santa Clarita area of Los Angeles County. The utility draws from three major sources: groundwater from the Main San Gabriel Basin, surface water from the San Gabriel River treated by Covina Irrigating Company, and treated surface water imported from the Metropolitan Water District of Southern California. The company maintains multiple treatment and distribution facilities across its service area. Its 2023 Consumer Confidence Report, filed with California's Division of Drinking Water, confirms compliance with all Federal and State drinking water standards, with sodium levels reported at approximately 69 mg/L and lead and copper compliance achieved through corrosion control treatment.
The Main San Gabriel Basin underlies the service area and consists of Quaternary alluvial deposits and older Tertiary sedimentary formations resting on Precambrian crystalline basement rock. The San Gabriel River watershed drains the San Gabriel Mountains and transits through similar sedimentary geology. These formations are naturally enriched in calcium and magnesium minerals, which dissolve readily into groundwater and surface runoff, creating the characteristically very hard water supply typical of much of Southern California.
Valencia's water is classified as very hard at 570 mg/L, meaning residents experience noticeable scale buildup on fixtures, reduced soap lathering, and potential damage to water heaters and appliances over time. A water softener is strongly recommended for households and businesses. While hard water does not pose a health risk, it creates aesthetic issues such as spots on glassware and porcelain, and increases energy costs as mineral deposits accumulate and reduce appliance efficiency over time.
Geology & Source: Main San Gabriel Basin — Quaternary alluvial and Tertiary sedimentary deposits overlying Precambrian crystalline basement; calcium and magnesium-rich minerals produce very hard supply

Data Sources & Methodology
Water quality data for Valencia 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.
