What Makes Glen Avon's Water Unique?
Local geology and source profile
Glen Avon, California, in Riverside County — an unincorporated Riverside County community in the Jurupa Valley along the Santa Ana River corridor adjacent to Mira Loma and Jurupa Valley — receives its municipal water from the Jurupa Community Services District or Western Municipal Water District (WMWD), which draws from the Riverside-Arlington Basin groundwater and Colorado River Aqueduct (CRA) import through the Metropolitan Water District (MWD) regional distribution system.
The moderately hard 124 mg/L hardness and TDS of 330.4 mg/L reflect the Riverside Basin's blended groundwater and CRA import character. The Riverside-Arlington Basin alluvial aquifer receives recharge from the Santa Ana River and local runoff draining the Jurupa Hills (Cretaceous granodiorite of the Peninsular Ranges — soft) and the Badlands (Tertiary conglomeratic sediment). The CRA Colorado River import adds harder water character, and the blend with older, more mineralized alluvial groundwater produces the moderately hard 124 mg/L outcome in the Jurupa Valley supply zone.
At 124 mg/L, Glen Avon's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.5 ppt warrants a certified drinking water filter — the March Air Reserve Base (Riverside County — a major AFFF user), the Riverside County industrial and manufacturing corridor, and the Santa Ana River basin's PFAS legacy contribute to Glen Avon's PFAS readings.
Geology & Source: Glen Avon in Riverside County draws from the Jurupa Community Services District or Western Municipal Water District (WMWD) on the Riverside Basin Groundwater and MWD Colorado River Aqueduct import — the Riverside Basin accesses the Rialto-Colton Basin alluvial aquifer blended with CRA import — alluvial basin groundwater and Colorado River Aqueduct blend produces moderately hard water at 124 mg/L with TDS 330 mg/L in this Riverside County California community.
