3. Scope of Work <br /> The planned scope of work for an initial screening of groundwater for contaminants at the Site from historical <br /> operations in the surrounding industrial area. This Preliminary Subsurface Investigation includes the <br /> collection of grab groundwater samples from two temporary borings on Site (Figure 2) advanced to 25 feet <br /> below ground surface (bgs). Roux will contract with Cascade Drilling, a C-57 drilling contractor, to conduct <br /> the drilling activities on Site. The first five feet of each boring will be advanced with a hand auger and the <br /> remaining depth of the boring will be advanced with a Direct Push Technology (DPT) Geoprobe rig. <br /> The grab groundwater samples will be analyzed for volatile organic compounds (VOCs) by U.S. <br /> Environmental Protect Agency(EPA)Method 8260B,total petroleum hydrocarbons as gasoline(TPH-g), and <br /> TPH as diesel and motor oil (TPH d/-mo) by EPA Method 8015/8015B, and PAHs by EPA Method 8270C (or <br /> equivalent). <br /> There will be no non-routine activities to be performed by Roux personnel. <br /> If there are any changes with the scope, a revision of the HASP will be required to address any new hazards. <br /> 5175.0001S102/HSP Site-Specific Health and Safety Plan I ROUX 18 <br />
