0 <br /> AEI Project No. 319400 <br /> May 22, 2013 <br /> Page 4 of 5 <br /> Soil in the borings will be continuously collected in liners within the sampling barrel from which <br /> a 6-inch sample will be collected at appropriate depths. The sample will be sealed with Teflon <br /> tape and plastic end caps. <br /> The soil borings will be logged using the Unified Soil Classification System. A photo ionization <br /> detector (PID) will be used to screen soil samples in the field and the PID readings for each <br /> sample will be included on the boring logs. <br /> Groundwater Sample Collection <br /> When first groundwater is encountered, a slotted PVC casing will be temporarily inserted into <br /> the borehole to facilitate groundwater collection. Groundwater samples will be collected using <br /> either a disposable bailer or peristaltic pump and decanted into the appropriate sample <br /> containers. The containers will be sealed so that no head-space or air bubbles are visible within <br /> the containers. <br /> Boring Destruction <br /> Following completion of sample collection and removal of tooling, the borings will be backfilled <br /> with neat cement grout as required by the permitting agency and completed at the surface with <br /> to match the surrounding conditions. <br /> Laboratory Analysis <br /> The soil and groundwater samples will be labeled and placed into a cooler with ice following <br /> sampling. All of the samples will be transferred under appropriate chain-of-custody <br /> documentation to a state-certified laboratory. <br /> Laboratory analysis of soil and groundwater samples from the area of the USTs and fuel <br /> dispensers (borings B-1 though 13-6) will consist of the following: <br /> • TPH multi-range (gasoline, diesel, motor oil) by EPA Method 8015M <br /> • BTEX and Oxygenates by EPA Method 8260 <br /> Laboratory analysis of soil or groundwater samples from the area of the former hydraulic lift <br /> (boring 13-7) will consist of the following: <br /> • TPH as hydraulic oil by EPA Method 8015 <br /> • Polychlorinated Biphenyls (PCBs) by EPA Method 8082 <br /> Waste <br /> Drill cuttings and purge water will be stored onsite in sealed 55-gallon drums, pending the <br /> results of sample analyses. Any equipment rinse water will also be stored in 55-gallon drums. <br /> Upon receipt of analytical data, the removal and disposal of the waste to an appropriate <br /> disposal facility will be recommended. <br /> 5.0 Estimated Schedule and Reporting <br />
