to P-8 (part of AGE investigation of the Pacific Pride site) on the sidewalk south of MW- <1 <br /> 4. Lithologic data from the AGE Report of Investigation will be used to locate sample <br /> depths for this boring. <br /> Each CPT boring will be advanced to 125 ft. bsg. This will result in penetration of three <br /> to four water zones. Water samples will be secured from each water zone for each boring, <br /> including the boring on the sidewalk south of MW-4 (using the AGE lithologic data) . - h <br /> ave HZ <br /> All samples will be secured using a hydropunch sample tool, either mounted on the CPT -Crr <br /> rig,k or a separate Geoprobe, ample depths will be determined using the lithologic data <br /> generated by the CPT. The sample boring will be adjacent to the CPT boring. In addition <br /> to water samples from all borings, soil samples will be secured representative of the first <br /> water zone from the two borings on the sidewalk, north and south of MW-4, to be <br /> analyzed for percent organic carbon by weight and total effective porosity. The <br /> associated water samples will be analyzed for dissolved oxygen, ferrous iron, nitrate and <br /> sulfate, in addition to the hydrocarbons of concern Finally, a water sample will be <br /> secured from MW4 to be analyzed for electron acceptors. These data will be used to <br /> ( �evaluate natural attenuation at these locations, oI rz�i as <br /> a <br /> All water samples will be analyzed for hydrocarbon contaminants as follows: <br /> • TPH gasoline, diesel and motor oil using LUFT GUMS . <br /> • BTEX, TBA MTBE, EDB, 1 ,2 DCA, DIPE, ETBE & TAME using EPA 8260B . <br /> Soil borings will be backfilled with cement grout, and all rinseate generated during <br /> drilling will be stored in labeled drums on-site for disposal in an approved manner. <br /> A Report of Investigation will be prepared at the completion of this work, which will <br /> include all lithologic and analytical data collected . Cross sections will be developed as <br /> shown on Figure 3 , and conclusions and recommendations for fixture work will be <br /> included . <br /> I <br /> 4 <br />
