4W <br /> Kennedy/Jenks Consultants <br /> The soil borings will be drilled in the vicinity of the former ASTs as shown on the boring <br />,a„ permit application (Appendix B). <br /> Soil samples will be continuously collected from near the surface to total depth. A <br /> Kennedy/Jenks geologist will lithoiogically log each boring using the Unified Soil <br /> Classification System (ASTM D2488-93). The soil samples will be screened in the field for <br /> the presence of volatile organic compounds using an organic vapor meter (OVM). Field <br /> documentation will include the completion of boring logs that record lithologies encountered <br /> during drilling of each boring, soil sampling intervals, and field samples headspace <br />+ measurements. Two soil samples will be collected from each boring for laboratory analysis <br /> based upon visual observation and OVM screening. <br />+W A reconnaissance groundwater sample will be collected from each boring. The sampling <br /> method generally consists of temporarily lowering a PVC-slotted well casing into the <br /> borehole, and collecting a sample of water that flows into the casing. Following the <br /> collection of soil and reconnaissance groundwater samples, each borehole will be grouted <br /> to the ground surface with cement/bentonite grout using the tremie method. These sample <br /> collection procedures are described in detail in Appendix A. <br /> Drill cuttings and wash water will be contained in either DOT-approved 55-gallon drums <br /> with bolt-on lids or 5-gallon pails, which will be sealed, dated, and labeled as to their <br /> contents. Investigation-derived residuals will be temporarily stored at the Site prior to <br /> disposal, pending receipt of laboratory analytical results for the samples. <br />.:q. <br /> Task 3 — Laboratory Analysis <br /> Soil and groundwater samples will be submitted to a state-certified laboratory for analysis. <br /> A chain-of-custody record will be completed for the samples and will accompany the <br /> samples until receipt by the laboratory. Selected soil and groundwater samples will be <br />.AW analyzed for: <br /> • TPH - fuel fingerprinting (modified EPA Method 8015) <br /> • Semi-volatile organic compounds (SVOCs) (EPA Method 8270) <br /> The fuel fingerprinting analyses will result in concentrations of petroleum hydrocarbons <br /> calculated over three carbon ranges: C6 to C10 (gasoline), C10 to C22 (diesel), and C22 to <br /> C36 (heavy oil). If petroleum hydrocarbons in the diesel or heavy oil range are detected in <br /> the fuel fingerprinting analyses, one soil and one groundwater sample will be analyzed for <br /> SVOCs. The SVOC analysis will help identify possible toxic constituents present in the <br /> petroleum hydrocarbons detected at the Site. <br /> A blind duplicate groundwater sample will be collected from one of the borings for quality <br /> assurance purposes. Duplicate samples are designed to monitor overall sampling and <br /> analytical precision. Duplicate samples will be assigned a unique sample number so that <br /> the laboratory is not aware that they are duplicates. <br /> 1:1jobTS 950073.00lrptlworkplanitext.doc 2 <br /> tih11 <br />
