GeoSyntec Consultants <br /> Himanshu H . Mehta, P . E . <br /> 11 November 2005 <br /> Page 2 <br /> correspondence indicating that the area of visually stained soils was very limited) . Once <br /> all visually impacted soil has been excavated (maximum of two drums of soil) a soil <br /> sample will be collected from the bottom of the excavation area for laboratory analyses <br /> for the Florida Used Oil Group (SW8260, SW8270, FLPRO, arsenic, cadmium, <br /> chromium, and lead) to confirm that the waste oil impacted soil has been removed . To <br /> provide documentation of the groundwater conditions beneath the area impacted by the <br /> waste oil release, GeoSyntec will install a temporary well point (with a pr pack well <br /> screen to reduce potential turbidity interferences) within the excavation area and collect <br /> groundwater samples for laboratory analyses for the Florida Used Oil Group . All soil <br /> and groundwater sampling activities will be performed in accordance with Florida <br /> Department of Environmental Protection Standard Operating Procedures . Upon <br /> completion of the excavation activities , the excavation area will be backfilled with clean <br /> fill (up to 15 ft3) and the disturbed area will be sodded . A soil sample will be collected <br /> from the drummed waste-oil impacted soils for disposal characterization . The drums <br /> containing the excavated soils will be labeled and stored on site pending laboratory <br /> analytical results . <br /> Upon receipt of laboratory analytical results for the drummed soils , GeoSyntec will <br /> coordinate with IRCDUS to have the soil disposal manifest signed and the soil properly <br /> disposed off-site . GeoSyntec will prepare a brief letter report which summarizes the <br /> field excavation activities and results of soil and groundwater sampling activities . The <br /> letter report will be signed/sealed by the Florida licensed professional engineer or <br /> geologist in responsible charge of the project . <br /> ASSUMPTIONS <br /> During the preparation of this proposal , GeoSyntec has made theollowing <br /> assumptions : <br /> • Access to sampling locations is not restricted to GeoSyntec. <br /> • All sampling can be performed in Level D personal protective equipment . <br /> • GeoSyntec will be able to work unimpeded between Monday and Frid y from 7 <br /> am - 7 pm . <br /> • The area of excavation is estimated to be 14 . 7 ft3 or less (two 55 -gallon Irums of <br /> soil) . <br /> R050076 — IRC Waste Oil Contaminated Soil Proposal <br />
