What Makes Huntington Park's Water Unique?
Local geology and source profile
Huntington Park, California, in south Los Angeles County between Bell and South Gate — a densely populated industrial city historically known for the Southeast Los Angeles Mexican-American working-class community, once described as the 'Mexican Beverly Hills' of the 1920s–1930s era for its then-prosperous community — draws its municipal water supply from the Central Basin of the Los Angeles Coastal Plain Groundwater Basin and Metropolitan Water District (MWD) imported water via the City of Huntington Park Public Works Water Division. Water hardness in Huntington Park measures 36.5 mg/L — classified as very soft.
Huntington Park's very soft supply reflects the south Los Angeles Central Basin's extensive MWD State Water Project recharge. The Central Basin (Los Angeles Central Groundwater Basin) in the south Los Angeles area is managed by the Central Basin Municipal Water District (CBMWD), which has developed extensive artificial recharge spreading grounds to inject soft MWD State Water Project Sacramento–Feather River water (very soft, 20–50 mg/L) into the basin. The dominant SWP recharge water fills the Huntington Park zone of the Central Basin, producing the very soft 36.5 mg/L — one of the softest municipal supplies in the Los Angeles metro area.
With hardness at 36.5 mg/L, Huntington Park residents enjoy very soft water with essentially no scale challenges. City of Huntington Park Public Works Water Division consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Central Basin (Los Angeles Coastal Plain) and Metropolitan Water District (MWD) imports via the City of Huntington Park Public Works Water Division — the south Los Angeles Coastal Plain alluvial basin; very soft supply at 36.5 mg/L — reflecting the Central Basin's extensive MWD SWP import recharge in the south LA urban core.
