Weber Street Mr <br /> Stockton, CA 95201 0 <br /> W <br /> Pro sed Groundwater Treatment Plan Site Code 22073 <br /> Van den Bergh Foods Company Stockton <br /> Dear Ms. Meays: <br /> On behalf of Van den Bergh Foods Company, we have attached our proposed treatment plan <br /> for the groundwater at the subject site, pursuant to your request. During the second quarter <br /> 1996 .groundwater sampling (May 1996), no detectable concentrations of TPH as diesel in the <br /> groundwater were measured. However, you had expressed concern that the TPH as diesel <br /> concentrations detected in soil at depth (<1,000 mg/kg) could significantly impact the <br /> groundwater quality at the site. Due to your concern, we are proceeding with the subject <br /> plan, to mitigate any potential impact to groundwater. <br /> We are proposing to use ORC® "filter socks" to increase the dissolved oxygen levels in the <br /> groundwater and thereby enhance the biodegradation of TPH as diesel that was detected in <br /> groundwater. We plan to install the ORO filter socks on Thursday, August 22, 1996. <br /> Should this date conflict with your schedule, please contact us as soon as possible. <br /> We appreciate your cooperation in this matter. Should you have any questions, please call <br /> me at (510) 372-5253. <br /> Sincerely, <br /> Linus Farias <br /> Project Manager <br /> Enclosure <br /> cc: Ms. Elizabeth Thayer, Central Valley RWQCB <br /> Mr. Frank Yoneshige, Van den Bergh Foods Co. <br /> Mr. Bud Kopp, Van den Bergh Foods Co: <br /> IT Corporation is a wholly owned subsidiary of Internotionai Technology Carparahon <br />
