What Makes East Hemet's Water Unique?
Local geology and source profile
East Hemet, California, in Riverside County — an unincorporated Riverside County community adjacent to Hemet and San Jacinto in the San Jacinto Valley of the Inland Empire — receives its municipal water from the Eastern Municipal Water District (EMWD), drawing from the State Water Project (SWP) via Diamond Valley Lake (Hemet) and local groundwater wells in the San Jacinto Valley alluvial aquifer.
The moderately hard 146 mg/L hardness and TDS of 411.6 mg/L (relatively high TDS for this hardness) reflect the San Jacinto Valley blended supply. The SWP delivers northern California Sierra Nevada snowmelt (insoluble granodiorite — very soft); local San Jacinto River alluvial wells draw from the Quaternary San Jacinto Valley alluvial fill mixed with the Cretaceous Peninsular Ranges batholith (granodiorite — moderately insoluble). The elevated TDS relative to hardness suggests the local groundwater component contributes higher dissolved solids.
At 146 mg/L, East Hemet'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 6.1 ppt warrants a certified drinking water filter — the Riverside County military corridor (March Air Reserve Base — AFFF, in the San Jacinto Valley watershed), the Inland Empire industrial complex, and the southern California PFAS background contribute to East Hemet's readings.
Geology & Source: East Hemet in Riverside County draws from Eastern Municipal Water District on the State Water Project and Diamond Valley Lake (Riverside County) — the SWP-local blend mixes Sierra Nevada snowmelt (insoluble) with San Jacinto Valley wells (Quaternary alluvium, Cretaceous Peninsular Ranges granite) — California Riverside County SWP-local supply produces moderately hard water at 146 mg/L with TDS 411.6 mg/L in this Riverside County city.
