Weber Ave.,3'Floor <br /> Stockton,CA 95202 <br /> Re: Response to Phone Calls–Sept 13, 1999 <br /> C& B Equipment,7474 West I Ith Street,Tracy,California <br /> Dear Mr.Rowe: <br /> In response to your phone calls September 13, 1999, Geological Techoics Inc. has prepared <br /> the,following information. <br /> Domestic Well Surma Request Letter: <br /> Comment: You requested that a copy of the letter to Gordon Boggs requesting that a water <br /> well survey be performed around the C&B property be sent to you, <br /> Response: Attached please find the letter Geological Technics sent to Mr. Boggs for his <br /> signature and the address of Mr. Jim Gibboney of DWR for him to send it to. <br /> We also requested a copy of the signed letter be returned to Geological <br /> Technics,but evidently was not returned since we do not have it in our files. <br /> Geophysical Testine: <br /> Comment: You requested that a copy of the geophysical testing results on the soil be <br /> submitted to you as outlined in the work plan. <br /> Response: In the course of preparing the Cost Pre-Approval request; the geophysics[ <br /> parameter testing was not included, Therefore the testing was not performed. <br /> At this point that data is not needed since the down gradient wells are not <br /> contaminated. If they were contaminated, then the geophysical data could be <br /> used to make basic fate and transport calculations to estimate the downgradient t <br /> extent of the plume migration. However, since the plume is defined, the C <br /> geophysical data is inconsequential. <br /> i <br /> Respectfully, <br /> GEOLOC2CS9L 9EC)f7VCS 29V17 <br /> Y <br /> Raynold 1.
