Agoura Water Hardness & Quality Report (2026)

Agoura, California, in Los Angeles County — an unincorporated Los Angeles County community in the Conejo Valley adjacent to Agoura Hills in the western Santa Monica Mountains corridor, a hillside community in the US-101 Ventura Freeway corridor of western LA County — receives its municipal water from the Las Virgenes Municipal Water District (LVMWD), which draws from the Metropolitan Water District (MWD) State Water Project import. LVMWD serves the Calabasas-Agoura-Westlake Village corridor almost exclusively on MWD-sourced water.

The very soft 32 mg/L hardness and very low TDS of 64.2 mg/L are essentially identical to Agoura Hills (batch-125 — 30 mg/L, TDS ~62 mg/L) — confirming both communities draw from the same LVMWD SWP supply system. The State Water Project water delivered through MWD to LVMWD originates in the Sierra Nevada snowmelt (Feather River, Sacramento River watersheds) — very soft, low-mineral water from the Sierra's crystalline granite terrain. LVMWD's service area has essentially no local groundwater production, making the SWP import the near-exclusive source and producing the very soft, very low TDS finished water characteristic of the western LA-Ventura County mountain-foothill corridor.

At 32 mg/L, Agoura's water is very soft — excellent for household use. Scale essentially never forms, soap lathers abundantly, and appliances maintain maximum efficiency. Annual descaling is more than sufficient. The PFAS level of 2.8 ppt is very good for the western LA corridor — the Rocketdyne Propulsion Field Laboratory (former) on the eastern Santa Susana Mountains (a significant aerospace chemical site), and the Malibu-Conejo corridor military and aerospace PFAS background are relatively limited, producing the low reading.
