r. <br /> �O <br /> IN r <br /> .r+ <br /> E S <br /> Wo <br /> Et�l contamination was apparent in the fuel pipe trenches. Confirmatory in-situ <br /> soil samples were collected from UST excavations on February B, and from the <br /> fuel and oil pipe trenches on February 21 (Table 1). Removal of USTs and <br /> r confirmatory sampling was performed in the presence of and with the <br /> concurrence of San Joaquin County Public Health Services Department and City <br /> � of Stockton Fire Department personnel. _Soil sampling is discussed in Section <br /> ( s 3.2 and analytical results are discussed in Section 5.0. <br /> r <br /> Excavated soils were placed in stockpiles and segregated as originating from <br /> �j <br /> either the "new" excavation, the fuel UST excavation, or the motor and used <br /> oil UST excavation. Composite soil- samples were taken from stockpiles in <br /> -order to determine appropriate disposal methods. Soil sampling is discussed <br /> in Section 3.2 and analytical results and disposal are discussed in Section <br /> l-i 5.0. <br /> 2.0 SCOPE OF WORK <br /> kilt <br /> IT's work pertained to environmental aspects of UST removal and replacement, <br /> ' n h terization an disposal of stockpiled soils from the UST excava- <br /> tions. <br /> � <br /> and c arac d p p ; <br /> tions.
