To date, none of the methods (chemical injection and dual-phase extraction) have <br /> been proven to be a feasible remedial method.The RWQCB directed the installation of a biosparge <br /> well to test the feasibility of biosparging as a remedial method. This scope of work involves the <br /> drilling of two CPT borings, one to determine lithology and one to collect soil samples, and the <br /> installation of one biosparge well to test the effectiveness of biosparging as a remedial method. <br /> Future work includes design and implementation of a full-scale remedial system at the site and <br /> eventual well destruction of all wells and probes associated with the Site once the Site has been <br /> granted closure.There are no current plans to redevelop the Site from its current use/configuration. <br />
