What Makes Studio City's Water Unique?
Local geology and source profile
Studio City, California, a neighborhood in the San Fernando Valley portion of Los Angeles in Los Angeles County — a major entertainment industry community (Studio City is named for the CBS Studio Center, formerly the Republic Pictures studio — one of the most active television production facilities in the entertainment industry; numerous major TV shows have been filmed at the Radford Avenue studio complex; Studio City is surrounded by entertainment industry professionals), home of the Ventura Boulevard commercial corridor (the Ventura Boulevard entertainment strip running through Studio City is one of the most well-known commercial streets in the San Fernando Valley, lined with restaurants, shops, and entertainment venues), a diverse Los Angeles County community with a significant Jewish-American, Persian-American, and entertainment industry professional population, and a primarily upscale residential neighborhood adjacent to the Santa Monica Mountains — draws its municipal water supply via the Los Angeles Department of Water and Power (LADWP). Water hardness in Studio City measures 164 mg/L — classified as hard.
Studio City's hard supply reflects the San Fernando Valley LADWP supply blend's calcareous characteristics. The LADWP San Fernando Valley supply at Studio City draws from: the San Fernando Valley Groundwater Basin (calcareous-moderate Quaternary alluvium); and the MWD Colorado River import (approximately 280–320 mg/L). The Studio City Valley distribution zone's Colorado River-blended supply produces the hard 164 mg/L.
At 164 mg/L, Studio City residents face regular hard water challenges. Monthly descaling with citric acid solution is recommended. LADWP consistently delivers water meeting all California State Water Board and EPA Safe Drinking Water Act requirements.
Geology & Source: Mountain reservoir supply via the Metropolitan Water District (MWD) of Southern California — the Los Angeles County San Fernando Valley Studio City corridor (MWD State Water Project (SWP) and Colorado River blend — the Los Angeles DWP San Fernando Valley supply; Studio City Valley distribution with effective treatment); hard supply at 164 mg/L in Los Angeles County.
