What Makes West Hollywood's Water Unique?
Local geology and source profile
West Hollywood, California, in Los Angeles County — a small but culturally significant city (West Hollywood is only 1.9 square miles — one of the smallest incorporated cities in Los Angeles County by area, yet one of the most culturally influential), renowned as one of the most prominent LGBTQ+ community centers in the United States (West Hollywood's Santa Monica Boulevard corridor is among the most iconic LGBTQ+ commercial and cultural districts in the world — WeHo Pride is a major annual event), home of the Sunset Strip (the legendary Sunset Boulevard entertainment corridor in West Hollywood — site of iconic rock and roll clubs, hotels, and music venues), and a diverse West Hollywood community balancing entertainment industry workers, LGBTQ+ community, and Russian-Jewish immigrant communities — draws its municipal water supply via MWD import through the City of West Hollywood Public Works. Water hardness in West Hollywood measures 56.5 mg/L — classified as soft.
West Hollywood's soft supply reflects the MWD State Water Project import's calcareous-poor characteristics. The MWD supply (primarily Sierra Nevada snowmelt via the California Aqueduct SWP) is exceptionally soft (approximately 30–60 mg/L). West Hollywood's direct MWD supply with minimal groundwater well contribution produces the soft 56.5 mg/L.
With hardness at 56.5 mg/L, West Hollywood residents enjoy soft water. City of West Hollywood Public Works consistently delivers water meeting all California State Water Board and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the West Basin Municipal Water District and Metropolitan Water District (MWD) import via the City of West Hollywood Public Works — the Los Angeles County west Los Angeles urban basin (Quaternary calcareous-poor Los Angeles Basin alluvium and MWD State Water Project/Colorado River blend; West Hollywood LA Basin distribution zone); soft supply at 56.5 mg/L in Los Angeles County.
