L. *ftw, \� <br /> sampler's initials. Any observations regarding the sampling process and field related activities <br /> or the surrounding environment which may affect the sampling quality will be noted in the log <br /> book. Each page of the log book will be dated along with the logger's initials and the project <br /> name. Any deviations from the sampling protocol or approved work plan will be entered in the <br /> log book. <br /> A WESTON sample label will be affixed to every sample container and will include the <br /> following information: project ID or project number, sample ID, date, time of sample <br /> collection, sampler's initials, analytes requested and preservatives used, if any. <br /> A Chain-of-Custody document will be initiated at the time of sampling and will accompany the <br /> sample until it is received by the laboratory. The Chain-of-Custody form shall be protected by <br /> y sealing it into a water tight plastic ziplock bag, placed with the samples during sample shipment. <br /> 3.2 Sampling Technique <br /> 3.2.1 Soil Sample Screening and Selection <br /> Each soil sample from the soil borings will be screened for the presence of hydrocarbon vapor <br /> using a FID or a PID.

The sleeves will be labeled and placed into ziplock plastic bags for <br /> temporary storage in a cooler :W"A f � pending transport to the laboratory. <br /> 3.2.2 Monitor Well Groundwater Sampling <br /> �. Before sampling, the groundwater elevation will be measured and recorded and the well will be <br /> purged of three to five casing volumes in order to obtain a representative groundwater sample. <br /> As a routine part of the monitoring program, the groundwater physical parameters of <br /> ,.. temperature, electrical conductivity and pH will be measured and recorded. <br /> The samples will be collected using a teflon bailer equipped with a thin nylon line. Groundwater <br /> collected in the bailer will be poured into the sample containers to minimize aeration of the <br /> sample. Containers will be completely filled and then tightly capped. The sample containers <br /> will then be labeled, sealed into individual ziplock baggies and placed into an insulated cooler <br /> �- with ice. <br /> 3.3 Equipment Decontamination <br /> All non-disposable equipment used will be decontaminated prior to sampling and between sample <br /> points. A solution of tap water and a laboratory grade cleaning detergent will be used to clean <br /> `W the equipment and deionized water of known quality will be used for rinsing. <br /> w. <br /> MXkRP'r SICMVCD.WM ! 04�194 <br /> 1.. <br />
