What Makes Canoga Park's Water Unique?
Local geology and source profile
Canoga Park, California, in the west San Fernando Valley — a community within Los Angeles (formerly the City of Owensmouth), known for its aerospace and industrial heritage adjacent to Warner Center and Chatsworth — draws its municipal water supply from the Metropolitan Water District (MWD) imported water (Colorado River Aqueduct and State Water Project) and local San Fernando Valley Groundwater Basin via the Los Angeles Department of Water and Power (LADWP) West Valley District. Water hardness in Canoga Park measures 98.5 mg/L — classified as moderately soft.
Canoga Park's moderate softness reflects the west San Fernando Valley LADWP supply blend's favorable State Water Project fraction. In the west San Fernando Valley (Canoga Park, Reseda, West Hills), the LADWP blend tends to carry a higher fraction of soft SWP Sacramento–Feather River water compared to the east Valley zones closer to the Owens River Aqueduct. The local San Fernando Valley Groundwater Basin — the Sylmar Basin and Canoga Park sub-basin of the west Valley — contributes moderate calcareous groundwater from the Quaternary alluvial fill of the Santa Susana foothills and Simi Hills drainage. The blend produces the moderate 98.5 mg/L at Canoga Park.
With hardness at 98.5 mg/L, Canoga Park residents enjoy moderately soft water with minimal scale challenges. LADWP consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Metropolitan Water District (MWD) imports (Colorado River Aqueduct and State Water Project) and local San Fernando Valley Groundwater Basin via the Los Angeles Department of Water and Power (LADWP) West Valley District — the west San Fernando Valley MWD–LADWP blend; moderately soft supply at 98.5 mg/L in Los Angeles County.
