recorded on monitoring well purge tables. The groundwater samples will be analyzed for TPH- <br /> g, TPH-d, TPH-j, BTEX and five fuel oxygenates. <br /> 3.5 EXCAVATION OF UNIDENTIFIED OBJECTS <br /> Two areas of uplifted asphaltic-concrete pavement in the second survey area, east of the CSMS, <br /> were surveyed in March 2000 using a metal detector and GPR. Metal was not detected at either <br /> of the two targets. The GPR indicated an object was located immediately beneath the pavement <br /> at each location. <br /> A backhoe and hand excavation equipment will be used to carefully remove the pavement, and <br /> expose the GPR-identified object at each location. Depending on the object, it will be removed <br /> from the ground and sealed in a DOT-approved, steel, 55-gallon drum. The drum will be labeled <br /> with the contents, the source of the contents, the date of accumulation, and a contact phone <br /> number. The excavation will be backfilled with suitable non-engineered fill material, <br /> compacted, wheel-rolled at the surface, planed, and a hot-asphalt patch applied to match the <br /> surrounding pavement. Photo-documentation of the excavation and investigation activities will <br /> be made. <br /> If the object(s) is considered to be hazardous to remove, it will left in place, covered by a steel <br /> plate, and the area marked to not disturb. <br /> 3.6 STORAGE AND DISPOSAL OF WASTES <br /> Drill cuttings and water collected during the soil drilling operation and groundwater sampling <br /> activities will be stored in DOT-approved, 55-gallon steel drums in a secure area at the Site. The <br /> contents of the drums and the dates of collection will be clearly marked on appropriate labels. <br /> All equipment, decontamination materials, and disposable personal protective gear will also be <br /> placed in drums. When the hazardous characteristics of the materials have been determined, they <br /> will be disposed of using proper procedures. <br /> 3.7 REPORTING <br /> Following the completion of the field activities, a Site investigation report will be prepared. The <br /> report will summarize all Site investigation activities, variations from the work plan, and include <br /> all pertinent laboratory reports, figures, tables, and appendices supporting the investigation and <br /> findings of the report. <br /> 10 <br /> 3027-03/104700.4766.230/JUL23'03 <br />
