2.2 Scope of Work The soil borings will be performed by V&W Drilling of Rio Vista, CA (C57 #658786) Boreholes will be drilled by both hand auger and hollow stem drilling methods The proposed hand auguring activities inside the shop and the inaccessible points were the drilling rig will not be able to gain entry, will be drilled by Del-Tech under the supervision of V&W The leted V &ll Drilling installation of the monitoring wells and drilled soil borings will be comp - They will use a truck mounted hollow stem auger drilling rig to complete thhee installation The subsurface geologic investigation and logging of the soil borings will be completed by Tim McDonald of Geological Technics All of the stated tasks will be supervised by Ray Kablanow, PhD, R G #5234 of Geological Technics Modesto, California All of the cuttings produced from this event will be placed on 6 mil plastic, covered and stored on site until analytical results have been received Soil screening with a photo ionization detector will be performed to monitor the presence of volatile aromatics during the auguring of the hand borings and a discrete soil sample will be collected for laboratory quantification at the interval showing substantial signs of petroleum hydrocarbons During all the drilling activities a discrete sample will be collected at five foot intervals These soil samples will be logged for their geological characteristics. At a minimum two discrete soil samples will be collected from each soil boring from appropriate horizons representing the vertical geologic strata and by field indications of contamination One sample from the vadose zone and one at the capillary fringe Each of the samples will be collected with a driven tube sampler utilizing a new, clean 2" x 6" brass sample tube The brass tubes containing the soil samples will be sealed with teflon tape,clean plastic end caps, duct tape, labeled and placed in a chilled ice chest To ensure sample integrity all drilling equipment and the drive sampler will be decontaminated with a steam cleaner between each sample point A sample Chain-of-Custody (COC) will be initiated and all samples will be labeled and entered into the (COC) at the time of collection The samples will be placed into a ice chest with ice or blue ice to maintain a level of 4 degrees celsius while in transit to the laboratory Samples submitted to Sherwood Analytical Laboratory in Hilmar, California, DHS Certification #1400 will be requested to be analyzed for TPH- Gasoline, TPH- Diesel & B T X E (EPA Method 8015 Mod 0 4
