All samples will be handled in accordance to procedures and chain-of- <br /> custody guidelines specified in Sections 8.3 and 8.4. Sample containers will be labeled in <br /> accordance with Section 8.4, sealed with tape and placed in coolers for transport to the <br /> appropriate laboratory. Samples will be collected and containers and placed in coolers as <br /> specified in Section 8.2 and in Tables 4-1 through 4-4. <br /> 6.1 Field Health and Safety Procedures <br /> A site-specific Health and Safety Plan has been prepared for this field investigation and is <br /> submitted under separate cover(Appendix B). The Health and Safety Plan details project-specific <br /> health and safety procedures that must be followed in the field, including safety equipment and <br /> clothing that may be required, explanation of potential hazards that may be encountered, and <br /> location and route to the nearest hospital or medical treatment facility. <br /> 6.2 Soil Sampling <br /> As shown in Figure 3-1, soil samples will be collected at eight locations on Weber Block. <br /> Approximate soil sampling locations (within a 10-foot radius of location shown on Figure 3-1) <br /> will be determined in the field based on accessibility, historic maps indicating locations of <br /> possible storage of hazardous substances, and visible signs of potential contamination (e.g., <br /> stained soils, odors, and field screening with a PID when drilling). Exact soil sample locations <br /> will be recorded in the field logbook as sampling is completed. A sketch of the sample location <br /> will be entered into the logbook and any physical reference points will be labeled. If possible, <br /> distances to the reference points will be given. <br /> The Diedrich probe (similar to Geoprobe direct push sampling apparatus) will be used for soil <br /> and groundwater sampling. The system utilizes an outer and inner rod that is driven <br /> simultaneously. The outer rod has an outside diameter of 1-314 inches and inside diameter of <br /> 1 114 inches. The inner rod has an outside diameter of 1-118 inches and an inside diameter of <br /> 518 inches. The probe system is operated with a CME 55 drill rig. The rods are pushed <br /> hydraulically with the top head of the rig. If the hydraulic rams meet refusal, an automatic <br /> hydraulically driven hammer is used to drive the rods. By using the CME 55 to operate the <br /> probe system, a hollow stem auger will be used to collect samples if the geology stops the probe <br /> system from reaching the desired depths. <br /> Soil samples will be collected as grab samples (independent, discrete samples) from a depth of <br /> 2 to 2.5 feet bgs and 5.5 to 6 feet bgs at sample locations WB-SB5 to WB-SB9 and at 5 feet <br /> intervals to the water table for samples locations WB-SBI through WB-SB3.
