Infurna: <br /> Please find attached a report dated January 9, 1996,which was prepared by Chevron's consultant,Blaine <br /> Tech Services,Inc. (Blaine Tech),to describe the results of groundwater monitoring that was performed at <br /> the subject site on November 30, 1995. <br /> During their November site visit,Blaine Tech gauged and sampled all nine site-related wells. The <br /> measured direction of groundwater flow was generally toward the northeast under a hydraulic gradient of <br /> 0.005 ft/ft. All groundwater samples were analyzed for the presence of TPHGas and BTEX constituents. <br /> Detectable concentrations of dissolved hydrocarbons were measured at all wells. The measured <br /> concentrations were similar to those detected during previous site monitoring events. <br /> Chevron's consultant,Terra Vac,recently completed the installation of three additional monitoring wells <br /> downgradient from the subject site. A report describing their procedures and findings is forthcoming. <br /> If you have any questions or comments,I can be reached at(510)842-8695. <br /> Sincerely, <br /> /T 'e- i <br /> Brett L.
