(Blaine Tech),to describe the results of groundwater monitoring that was <br /> performed at the subject site on October 31, 1995. <br /> During their October site visit,Blaine-Tech gauged and sampled seven.of the fourteen site-related wells. <br /> The remaining seven are completed above the present.groundwater levelAll groundwater samples were <br /> analyzed for the presence of TPHGas and BTEX constituents. <br /> The measured direction of groundwaterflow.during October was toward the east-southeast.Detectable <br /> concentrations of dissolved hydrocarbons were measured,at wells'MW-9 and MW-13. The measured <br /> concentrations were consistent with those detected during previous site monitoring events.The y <br /> groundwater results at all other wells were non-detect. J <br /> If you have any questions or comments,I.can be reached at(510) 842-8695. <br /> Sincerely, <br /> _ <br /> Brett L.Hunter - - - - - - <br /> Environmental Engineer . <br /> Site Assessment and Remediation <br /> Re ycrtUte <br />
