What Makes Emeryville's Water Unique?
Local geology and source profile
Emeryville, California, in Alameda County — an Alameda County city adjacent to Oakland and Berkeley on the east shore of San Francisco Bay — receives its water from the East Bay Municipal Utility District (EBMUD), drawing from Pardee Reservoir on the Mokelumne River through the East Bay California distribution.
The soft 71.5 mg/L hardness and TDS of 166.3 mg/L reflect the Alameda County Mokelumne supply's soft Sierra Nevada character — the Mesozoic Sierra Nevada Granodiorite is highly insoluble, producing the naturally soft water characteristic of Sierra snowmelt runoff (compare Oakland CA: 70/163 in Alameda County comparable; Berkeley CA: 73/170 in Alameda County comparable; Emeryville consistent soft from the same Alameda County EBMUD Mokelumne River Sierra Nevada supply). The Mokelumne watershed at Alameda County — Mesozoic Sierra Nevada Granodiorite (insoluble — primary dilutant), Quaternary Delta alluvium (slightly calcareous — primary hardness contributor), and Holocene Bay Area alluvium (slightly calcareous — minor TDS).
At 71.5 mg/L with TDS 166, Emeryville's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 4.1 ppt is moderate — a certified drinking water filter provides added protection. Review EBMUD's annual water quality report for the latest contaminant monitoring data, particularly regarding Emeryville's industrial brownfield legacy.
Geology & Source: Emeryville in Alameda County draws from East Bay MUD on Mokelumne River aqueduct (Alameda County, north California) — the Mokelumne watershed at Alameda County drains Mesozoic Sierra Nevada Granodiorite (insoluble) and Quaternary Delta alluvium (slightly calcareous) — California Alameda County Mokelumne River Sierra Nevada supply produces soft water at 71.5 mg/L with TDS 166.3 mg/L.
