Honeybaked Ham Company, Inc. July 29, 1994 <br /> Project No. 200439-02 <br /> The site is located at 6530 Pacific Avenue, southeast of the intersection of Ben Holt Drive and <br /> Pacific Avenue, in Stockton, California (Figure 1). The site is currently occupied by a vacant <br /> bank building and parking areas. The property and building are owned by The Bank of <br /> America (BOA). Ninyo &Moore was retained by Honeybaked Ham Company,Inc. (HBHC), <br /> to perform a property transfer environmental site assessment of the site. <br /> Our previous study (Ninyo & Moore, 1994b) indicated that the site is located within <br /> approximately 200 feet of two gasoline stations with leaking underground storage tanks <br /> (Chevron at 6633 Pacific Avenue, and Exxon at 6425 Pacific Avenue). Groundwater beneath <br /> these two gasoline stations has reportedly been contaminated with petroleum hydrocarbons <br /> including gasoline and benzene, toluene, ethylbenzene and xylenes (BTEX). The SJCEHD <br /> Underground Storage Tank (UST) Cleanup Unit stated that based on currently available <br /> data there is no indication that contamination from these two gasoline stations has migrated <br /> beneath the subject site. However, a representative of the SJCEHD indicated that <br /> groundwater remediation has yet to begin at these two properties and that further migration <br /> of groundwater contamination is possible. In addition, our study indicated that the subject <br /> site is Iocated in the immediate vicinity of a plume of chlorinated solvent (halogenated <br /> organic compounds) contaminated groundwater. This plume reportedly originated at the <br /> Lincoln Center Shopping Center located directly west of the site, across Pacific Avenue. A <br /> representative of the California Regional Water Quality Control Board,Central Valley Region <br /> (RWQCBCV), indicated that delineation of the horizontal and vertical extent of this plume <br /> has been inconclusive and that the responsible parties will be requested to perform <br /> additional work to further delineate the extent of the plume. <br /> SUBSURFACE SAMPLING <br /> Subsurface samples were collected from the approximate locations shown on figure 2. The <br /> sampling locations were selected based on proximity to areas of concern in the site vicinity. <br /> The sampling locations (SP-1 and SP-2) were evaluated for the presence of subsurface <br /> structures by a subsurface geophysical survey, prior to commencement of sampling. <br /> 2 #dnY®&*'M8sP- <br />
