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 />
