The water distributed by Monte Vista Water District that our customers receive at their taps meets or exceeds all state and federal drinking water standards set to protect public health. Groundwater produced by MVWD’s wells requires very minimal treatment prior to distribution. However, the groundwater basin from which MVWD draws water has areas of high concentration of nitrates, a salt that at certain levels may pose a health risk to vulnerable populations. MVWD currently uses ion exchange treatment to remove nitrates from the pumped groundwater. The Plant 30 Wellhead Treatment Project will add granular-activated carbon (GAC), which is recognized by the State of California as the “best available technology” to remove TCP and improve drinking water quality for MVWD customers.
