j r � LI �� typically represent the highest PID reading recorded for each soil boring and the sample just above first-encountered groundwater. Sample Documentation The following will be used during sampling and analysis to provide chain-of custody control during sample handling from collection through storage. Sample documentation will include the use of the following: • Labels to identify individual samples • Chain-of-custody record sheets for documenting possession and transfer of samples • Laboratory analysis request sheets for documenting analyses to be performed Sample labels will contain the following information: • Project number • Sample number • Sampler's initials • Date and time of collection Sampline and Analysis Chain-of-Custody Record The Sampling and Analysis Chain-of-Custody Record, initiated at the time of sampling, contains, but is not limited to, the well number, sample type, analytical request, date of sampling, and the name of the sampler. The record sheet will be signed, timed, and dated by the sampler when transferring the samples. A copy of the Sampling and Analysis Chain-of-Custody Record is returned to Stratus Environmental, Inc. with the analytical results. Stockpiled Drill Cuttings and Soil Sampling Soil generated during drilling operations will be stockpiled on-site. The stockpile will be set on and covered by plastic sheeting in a manner to prevent rain water from coming in contact with the soil. Prior to collecting soil samples, Stratus personnel will calculate the approximate volume of soil in the stockpile. The stockpile will then divided into sections, if warranted, containing the predetermined volume sampling interval. Soil samples will be collected at 0.5 to 2 feet below the surface of the stockpile. Four soil samples will be collected from the stockpile and composited into one sample by the laboratory prior to analysis. The soil samples will be collected in cleaned brass, two by six inch tubes using a hand driven sampling device. To reduce the potential for cross-contanlination between samples, the sampler will be cleaned between each sampling event. Upon recovery , the sample container will be sealed at each end with Teflon sheeting and plastic caps to minimize the potential of volatilization and cross-contan I ination prior to chemical analysis. The soil sample will be labeled,placed on ice, and delivered to a state-certified analytical laboratory, along with the appropriate chain-of-custody documentation. APPENDIX-soil boring
