The project involves implementation of a water treatment system and other improvements that would help to remove groundwater contamination from the Charnock groundwater sub-basin and restore this resource as a water supply for the City of Santa Monica. The project involves implementation of a water treatment system and other improvements that would help to remove groundwater contamination from the Charnock groundwater sub-basin and restore this resource as a water supply for the City of Santa Monica. Improvements are proposed at two existing City-operated water service facilities; the Charnock Well Field site and the Santa Monica Water Treatment Plant (SMWTP). The improvements proposed at the Charnock Well Field site involve the installation of a Granular Activated Carbon (GAC) absorption system to treat contaminated groundwater from three wells within the Charnock well field. The proposed improvements at the SMWTP facility include demolition of three onsite structures and installation of a greensand filtration facility, reserve osmosis facility, air striping decarbonators, chemical storage and feed facilities for disinfection and fluoridation and electrical upgrades. The treatment process includes filtration using greensand filters to remove iron and manganese and a softening system utilizing reverse osmosis membrane technology.
