What Makes Fairview's Water Unique?
Local geology and source profile
Fairview, California, in Alameda County — an Alameda County unincorporated community adjacent to Castro Valley and San Lorenzo in the east San Francisco Bay Area — receives its water from the East Bay Municipal Utility District (EBMUD), drawing from the Mokelumne River aqueduct and local East Bay sources through the east Bay Area distribution.
The hard 131.5 mg/L hardness and TDS of 363.1 mg/L reflect the Alameda County supply's hard blended East Bay character — the Miocene Briones Formation and Quaternary East Bay Hills alluvium are slightly calcareous-calcareous formations in the East Bay Hills; Fairview's supply blends Mokelumne River imported water with local East Bay groundwater, concentrating moderate to hard mineral content in the east Bay Area flatlands (compare Castro Valley CA: 127/353 in Alameda County comparable; San Lorenzo CA: 135/373 in Alameda County comparable; Fairview consistent hard from the same Alameda County Mokelumne watershed Miocene supply). The Mokelumne/East Bay supply — Miocene Briones Formation (slightly calcareous — secondary contributor), Quaternary East Bay Hills alluvium (calcareous — primary hardness contributor), and Quaternary Bay Area alluvial fan deposit (calcareous — TDS contributor).
At 131.5 mg/L with TDS 363, Fairview's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 5.8 ppt warrants a certified drinking water filter. Review EBMUD's annual water quality report.
Geology & Source: Fairview in Alameda County draws from the East Bay Municipal Utility District on the Mokelumne/local blend supply (Alameda County, east San Francisco Bay Area) — the East Bay Hills at Alameda County draws from Miocene Briones Formation (slightly calcareous) and Quaternary East Bay Hills alluvium (calcareous) — California Alameda County Mokelumne watershed Miocene supply produces hard water at 131.5 mg/L with TDS 363.1 mg/L.
