What Makes Wildomar's Water Unique?
Local geology and source profile
Wildomar, California, in Riverside County — a major southwest Riverside County community incorporated in 2008 (Wildomar incorporated as a city in 2008 — one of the newest incorporated cities in Riverside County, carved from the unincorporated Elsinore Valley area), located in the Temecula Valley–Lake Elsinore corridor (one of the fastest-growing areas in California — the southwest Riverside County corridor has had dramatic population growth since the 1990s), adjacent to Lake Elsinore and the Elsinore Valley Municipal Water District service area, and a diverse Riverside County community with a significant Latino-American and military family population (adjacent to Camp Pendleton) — draws its municipal water supply via the Elsinore Valley Municipal Water District (EVMWD). Water hardness in Wildomar measures 133.5 mg/L — classified as moderately hard.
Wildomar's moderate hardness reflects the Elsinore Valley Municipal Water District's supply blend characteristics. The EVMWD supply at Wildomar–southwest Riverside County draws from: the Elsinore Valley Alluvial Aquifer (calcareous-moderate Quaternary alluvium in the Elsinore Valley — with some Colorado River-sourced recharge); and the MWD import blend (SWP and Colorado River water). The EVMWD blend produces the moderate 133.5 mg/L.
At 133.5 mg/L, Wildomar residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Elsinore Valley Municipal Water District consistently delivers water meeting all California State Water Board and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Elsinore Valley Municipal Water District (EVMWD) and Metropolitan Water District (MWD) import via the Elsinore Valley Municipal Water District — the Riverside County southwest Temecula Valley corridor (Quaternary calcareous-moderate Elsinore Valley alluvium and MWD Colorado River/SWP blend; EVMWD southwest Riverside County distribution); moderately hard supply at 133.5 mg/L in Riverside County.
