Drinking Water Replacement

The MTBE Contaminated Wells Are Currently NOT Being Used.

The MTBE contaminated wells are NOT currently being used for supplying drinking water.  Soon after the discovery of the MTBE pollution at the City of Santa Monica's wellfield, these wells were shut down.  Southern California Water Company then shut down their wells in order to prevent the spread of contamination to these wells.

City of Santa Monica Charnock Well Number 13 (shut down since 1996)
Since 1996, the City of Santa Monica and Southern California Water Company have purchased replacement water from the Metropolitan Water District. A small group of the parties with responsibility for potential source-sites (Shell and Chevron, joined in 1998 by Exxon) reimbursed the City and Southern California Water Company for these costs until January 2000. The Agreements under which these parties reimbursed the City and State for water replacement expired in January 2000. Enforcement orders from EPA and the Los Angeles Regional Water Quality Control Board now require a total of 16 parties to provide water replacement until January 2005.  The cost of this replacement water is approximately $3.2 million per year. 

Water replacement orders are available in PDF format.

Where does the water come from (for residents of Santa Monica and Culver City/West Los Angeles)?

For Santa Monica Residents 

Prior to 1996, Santa Monica residents received a portion of their water from the groundwater at the Arcadia Wellfield near Wilshire and Bundy and the Charnock Wellfields. The rest of Santa Monica's water, about 50%, came from surface water imported by the Metropolitan Water District via the State Water Project Aqueduct from Northern California rivers and the Colorado River Aqueduct. Since 1996, when Santa Monica's Arcadia and Charnock Wellfields were shut down due to MTBE, about 95% of the city's water has been from imported water supplied by the Metropolitan Water District. The remainder of Santa Monica's water comes from the Olympic Sub-Basin wells, which have not been impacted by MTBE contamination.

Palms/Mar Vista/Culver City Residents 

Residents in the Palms, Mar Vista, and Culver City areas receive their water from either the Los Angeles Department of Water and Power or the Southern California Water Company.

Prior to 1996, residents who receive water from the Southern California Water Company received a portion of their water from the company's Charnock Wellfield. Since 1996, when the company's wellfield was shutdown after MTBE was detected in Santa Monica's Charnock Wellfield, Southern California Water Company customers have received only treated surface water imported by the Metropolitan Water District from Northern California Rivers and the Colorado River Aqueduct.

Residents who receive water from the Los Angeles Department of Water and Power have received only treated surface water imported by the Metropolitan Water District from the State Water Project, Colorado River Aqueduct, and via the Los Angeles Aqueduct from the Owens Valley.

Is the water I drink tested for MTBE? 

Yes. The California Department of Health Services requires that all drinking water sources be tested for MTBE at least once annually. Water suppliers often test more frequently for MTBE voluntarily. For further information on the quality of your drinking water, see below.
