The CUF <br /> concurs with the EHD that additional remediation is necessary to achieve water quality <br /> objectives in a timely manner. <br /> The consultant had proposed investigating the potential use of insitu chemical oxidation (ISCO) <br /> to address the contaminants, but has found high sodium and other dissolved metals <br /> concentrations in groundwater. The consultant is reevaluating ISCO and may propose an <br /> alternative technology. Questions or comments should be directed to Lori Duncan at (209)468- <br /> 0337 or to Nuel Henderson at (209) 468-3436. <br /> Sincerely, <br /> Lori Duncan, REHS Nuel Henderson, PG <br /> Senior Registered Environmental Engineering Geologist <br /> Health Specialist <br /> Annual 5-Year Review Update Response.doc <br />
