FRESNO, Calif. – The Bureau of Reclamation has released final environmental documents for a pilot project for Widren Water District that would allow the district to convey up to 1,000 acre-feet of reverse osmosis treated groundwater through the Delta-Mendota Canal and potentially store it in San Luis Reservoir. The pilot project is part of a larger effort aimed at reducing dissolved minerals like salt and selenium in a 97,000 acre area known as the Grassland Drainage Area.

Widren Water District, located in northwestern Fresno County west of Firebaugh, has recently constructed a reverse osmosis treatment plant to extract and treat its in-district shallow groundwater. It has been shown in the region that removal of shallow groundwater can assist in reducing drainage impacts by lowering poor-quality drain water below the crop root zone.

A final Environmental Assessment and Finding of No Significant Impact were prepared in accordance with the National Environmental Policy Act, and are available at
