KennedyiJenks Consultants samples and/or a reconnaissance groundwater sample. The reconnaissance groundwater sampling techniques are described in Appendix C. 2.2.3 Management of Investigation-Derived Residuals Kennedy/Jenks anticipates generating up to one 55-gallon drum of soil cuttings and one 55-gallon drum of groundwater purge/equipment decontamination water. We will place the material in DOT approved drums and label them as to their contents. Appropriate disposal of the residuals will depend upon concentrations of constituents of concern found in the samples collected. 2.3 Laboratory Analyses All samples collected for laboratory analysis will be stored at 4°C in pre-cleaned coolers. Standard chain-of-custody procedures will be followed when the samples are transmitted to a California certified analytical laboratory. After collection, the sample will be labeled, placed in a watertight bag and, immediately placed on ice in a cooler for temporary storage. At the end of each day, and prior to the transfer of the samples offsite, chain-of-custody entries will be made for all samples. The chain-of-custody form will be completed and will identify the sample number, location, depth, date of collection, and the specific analytical requests for that sample. Finally, information on the labels will be checked against chain-of-custody forms, and the samples will be recounted before being submitted for analysis. All samples will be transported to the laboratory with completed chain-of-custody forms. Based on field screening, up to 2 soil samples per boring will be analyzed for total petroleum hydrocarbons as gasoline (TPHg) using Modified EPA Method 8015, benzene, toluene, ethylbenzene and total xylenes (BTEX), and methyl-tertiary-butyl-ether (MTBE) using EPA Method 8020, and total lead using EPA Method 6010/7000. If any groundwater samples are collected, they will also be analyzed for the same constituents. is\job\96\966070.01\workplan\text.doc 3
