What Makes Cherryland's Water Unique?
Local geology and source profile
Cherryland, California, in Alameda County — an unincorporated Alameda County community adjacent to Hayward and San Lorenzo in the east San Francisco Bay — receives its water from the East Bay Municipal Utility District (EBMUD), drawing from the Mokelumne River (Alameda County) through the east Bay Area distribution.
The soft 75 mg/L hardness and TDS of 176.2 mg/L reflect the east Bay Area EBMUD Mokelumne River supply's low Sierra Nevada granite character — consistent with other EBMUD east Bay communities (Oakland: ~72 mg/L; Berkeley: ~74 mg/L). The Mokelumne River at the EBMUD Pardee and Camanche reservoirs drains the Sierra Nevada — Mesozoic Sierra Nevada Batholith (granite — insoluble, primary supply), Precambrian metamorphic basement (slightly calcareous — minor hardness contributor), and Tertiary volcanic input. The insoluble Sierra Nevada granite produces the soft east Bay Area supply.
At 75 mg/L, Cherryland's water is soft — light scale forms slowly, soap lathers well, and appliances maintain good efficiency. Semi-annual descaling is appropriate. The PFAS level of 4.2 ppt warrants a certified drinking water filter — the Alameda County east Bay Area industrial corridor and Alameda Naval Air Station (legacy AFFF — closed but legacy plume) contribute to Cherryland's readings.
