The sampling and analysis plan has been prepared based upon the Scope of Work and is site- <br /> specific. The SAP presents the sampling objectives, sampling techniques and procedures, <br /> decontamination procedures, sample handling procedures, quality assurance/quality control, and <br /> field-related documentation that will be employed for field sampling during the site investigation <br /> activities. <br /> 1. SOIL SAMPLING <br /> 1.1 Field Immunoassay Testing <br /> The field screening test kit will be utilized to analyze the soil for total petroleum hydrocarbons. <br /> The field screening kit is called PetroFLAG and is manufactured by Dexsil Corporation. The <br /> screening samples will be taken at each face of the two excavations and additional samples may <br /> be taken upon the discretion of the Field Manager. A stainless steel trowel will be utilized to <br /> collect the samples and placed into a ziplock bag with a label indicating the location, including <br /> depth, of the sample. The samples will then be analyzed to determine if the excavations have <br /> removed TPH impacted soil to a level below the action level. The sampling kit analyzes for TPH <br /> from non detect, ND, to 100 ppm with a detection limit of 10 ppm for hydraulic fluid and 13 <br /> ppm for diesel fuel. The procedure takes approximately 20 minutes and up to 20 samples can be <br /> run simultaneously. <br /> Clean soil for Backfill <br /> One grab sample per 50 cubic yards will be taken from the segregated clean pile of excavated <br /> soil to be used as backfill and analyzed for TPH hydraulic oil and diesel via the PetroFLAG kit <br /> and by the fixed laboratory for confirmation. <br /> Rough&Ready Island 1 Tetra Tech, Inc. <br /> Revised Draft SAP November 18, 1998 <br />
