building, under a shed like roof, located behind the warehouse <br /> facing Hazelton Avenue, with the closest cross street Lincoln Road. <br /> A Boring, identified as B-T, was placed by JPCA on June 24 , 1994 , <br /> approximately in the center of the former UST and extended to the <br /> saturated zone, approximately 35 feet. Soil samples were collected <br /> at each five feet commencing at 11 feet. A grab water sample was <br /> collected. Figure 2 presents the location of the former UST area <br /> and B-T. ' <br /> The soil and groundwater samples were analyzed for Total Petroleum <br /> Hydrocarbons as Gasoline (TPHG) and Benzene, Toluene, Ethylbenzene <br /> and Xylene (BTEX) using Modified EPA Methods 8015/8020 . <br /> Based on the results of the analysis from the initial boring, San <br /> Joaquin County Environmental Health Division (SJCEHD) required an <br /> additional subsurface investigation to better define the extent of <br /> the soil and possible groundwater contamination. JPCA addressed <br /> the county requirements and prepared a workplan which was accepted <br /> by SJCEHD. <br /> A permit was requested and received from SJCEHD prior to drilling <br /> the three borings and three monitoring wells. In October 1994 , the <br /> borings and wells were completed with soil and groundwater samples <br /> collected for analysis. The borings were identified as MW-1 , MW-2 , <br /> MW-3 , B-1 , B-2 and B-3 . <br />•� Soil samples collected from a depth of 20 feet to groundwater at <br /> approximately 30 feet were analyzed and contained gasoline and <br /> gasoline constituents. The soil samples from borings B-1 and B-3 <br /> located north and south of the former UST had no detectable <br /> concentrations of TPHG and/or BTEX. <br /> The soils samples from the former UST pit area and in what maybe <br /> identified as the area extending in the south west quadrant from <br /> the UST pit had high concentrations of TPHG and BTEX especially in <br /> the area below the former UST at approximately 15 to 25 feet below <br /> grade. The soil samples collected from the borings identified as <br /> MW-1 , MW-2 and B-2 had high concentrations of TPHG and BTEX <br /> commencing below 20 feet and continuing to approximately 30 feet <br /> below grade. The water bearing zone commences at approximately <br /> some 17 feet below grade. A clay lens was encountered during the <br /> well drilling at approximately 40 feet below grade. A decision to <br /> not penetrate this clay layer was made to avert contamination from <br /> the first water bearing aquifer. <br /> Groundwater samples collected from the wells contained actionable <br /> levels of gasoline and gasoline constituents. <br /> The results of the samples collected from the soil borings are <br /> shown in Table 2 as a separate table at the end of this quarterly <br /> report. All concentrations of TPHG and BTEX are in parts per <br />• 2 <br />
