• 2.0 Purpose and Scope of the Investigation 2.1 Purpose The purpose and scope of the project is to take soil samples at two locations identified on Figure 2 and conduct laboratory analysis for the presence of Volatile Organic Compounds (VOC)and Total Petroleum Hydrocarbons Diesel Range Organics (TPH-DRU). The scope of work will consist of the following: • Collecting soil samples from two boring Locations; • Analyzing soil samples for VOC using EPA Method 8260 and TPH-DRO by EPA Method 8015;and • Preparing a soil sample report of site activities and analytical results. 2.2 Drilling and Sampling Procedures Drilling will be accomplished using a truck mounted auger. The south boring will be advanced to a depth of 15 feet with soil samples collected at about 5 and 14 feet:below ground surface(bgs). The north boring will be advanced to a depth of 5 feet with a sample collected at about 3 feet bgs. The samples will be placed in discreet laboratory supplied containers for analysis. All samples will be labeled with a unique alpha-numeric identifier, site location, name of sampler, etc.; placed in a cooler to keep them at the appropriate temperature (40 C) and delivered to a state certified laboratory as soon as possible. A Chain of Custody form will be completed for the samples prior to leaving the site. 2.3 Laboratory Analysis Laboratory analysis will be undertaken at Curtis and Tompkins Ltd., located at 2323 Fifth Street,Berkley, California 94720. The soil samples will be analyzed for VOCs using EPA Method 8260, and for Total and TPH DRO using EPA Method 8015. 2.4 Boring construction/deconstruction methods The boring will be advanced using a truck-mounted rig with an eight inch diameter hollow-stem auger. Samples will be collected at appropriate intervals using a moci lied California-style sampler. Upon completion of the boring the hole will be backfilled using cement grout. The modified California-style sampler will be decontaminated between each environmental sample using a non-phosphate detergent and distilled water and rinsed with distilled water. Augers and center plugs and other drilling equipment that comes into contact with subsurface soils will be decontaminated before removal from the site using a pressure washer;water will be collected in a tub or basin. 2.5 Disposal of soil and/or water generated Soils generated during boring activities and water generated during decontamination activities will be drummed in separate labeled metal 55-gallon drum and stored on site until analytical results of the contents are received so as to determine the appropriate disposal method.
