16.e %.w Honeybaked Ham Company, Inc. June 14, 1994 Project No. 200439-02 research has also revealed that the subject site is located in the immediate vicinity of a plume of chlorinated solvent contaminated groundwater. This plume reportedly originated at the Lincoln Center (shopping center) Iocated directly west of the site, across Pacific Avenue. A representative of the California Regional Water Quality Control Board, Central Valley Region (RWQCBCV), indicated that definition of the horizontal and vertical extent of this plume is incomplete and that the responsible party will be requested to perform additional work to fully define the extent of the plume. Based on the findings of our preliminary research,we recommended to HBHC that a limited subsurface evaluation of soil and groundwater at the subject site be performed. At the direction of HBHC and in accordance with SJCEHD requirements, we have prepared this work plan. The work plan includes the following scope of services which are based on our research completed to date. Scope of Services Ninyo & Moore's proposed scope of work includes the following: • Obtain the appropriate permits from SjCEHD to perform the proposed work(see attached SjCEHD Application Package). • Perform a subsurface geophysical survey to clear two selected sampling locations of subsurface interferences. Sampling locations, shown on Figure 1, attached, were selected based on proximity to areas of concern in the site vicinity. • Collect two soil and one in-situ groundwater sample from each of the two sampling locations using the Stratoprobe Sampling System (Stratoprobe) of Transglobal Environmental Geochemistry (TEG) of Sacramento, California. The Stratoprobe operates in a manner similar to a soil vapor probe. A 1.5-inch diameter, hollow, stainless steel rod is hydraulically driven into the subsurface. Relatively undisturbed soil, and in-situ groundwater samples are collected from the probe tip at the selected depth intervals. Collection of soil and groundwater samples with the Stratoprobe will not produce waste material or leave any structures in the ground. Soil samples will be collected from depths of approximately 10 and 40 feet below surface grade (bsg) at each of the two sampling locations. Soil samples will be collected by driving pre-cleaned brass tubes into the soil. Groundwater is reportedly located approximately 45 feet bsg in the site vicinity. Groundwater samples will be collected with a stainless steel bailer and placed, with no visible 2 vins®&MOUr,
