' 18 April 2000 <br /> . AGE-NC Project No 98-0534 <br />' Page 4 of 9 <br />' The total depth of the T1 excavation was five feet bsg Field observation indicated a minor <br /> hydrocarbon-impact to soil the floor of excavation T1 Hydrocarbon-impacted soil in the DT <br /> excavation was not observed I <br /> rSoil samples were collected from the DT and the Tl excavation side walls at depths of 3 feet bsg and <br /> two soil samples were collected from floor of the T1 excavation at a depth of five feet bsg <br /> On 13 October 1999, the stockpiled soil from the UST removal and over-excavation was transported <br /> to Forward Landfill for final disposal Tracking records of the disposal are in Appendix A <br /> I <br /> 32 PROBE BORINGS AND SAMPLING <br />' On 02 and 03 November 1999 a total of 10 soil10 P h 1 throe P robe borings were advanced at <br /> p g ( g } <br /> the site, under observation by the PHS-EHD Probe borings were advanced in the area of the former <br /> USTs, over the former dispenser island locations and northwest of the former dispensers to collect <br /> grab water samples Probe boring P3 was advanced to a depth of 15 feet below surface grade Probe <br /> borings P1, P2, P4, P5, P7, and P8 were advanced to a depth of 25 feet below surface grade (bsg), <br /> borings P6, P9, and P 10 were advanced to 30 feet bsg, Locations of the soil probe borings are <br /> illustrated on Figure 2 <br /> SO11 in the probe borings was sampled using a Geoprobe soil sampling device loaded with four 6- <br /> inch by 1 125-inch brass sleeves Soil samples were collected at five-foot intervals The second <br /> sleeve collected was covered with Teflon sheets, capped and sealed with tape All samples were <br /> uniquely labeled <br /> I Collected samples preserved for laboratory analysis were placed in a chilled container, under ice, and <br /> transported to McCampbeil Analytical, Inc, (MAI)under chain-of-custody The sampling equipment <br /> was washed in an Alconox solution and rinsed with water prior to each sampling run to avoid cross- <br /> contamination <br /> All probe borings were permanently sealed to prevent vertical migration of contaminants Soil <br /> Eborings were abandoned by backfilling with cement slurry from the total depth to surface grade <br /> 3 3 SOIL LOGGING <br /> I After sample preservation, soil was extruded from the remaining sleeves and screened utilizing <br /> organic vapor meters (OVMs), equipped with a photo-ionization detector (PID Thermo <br /> • <br /> Advancer(GeoEnvironmental,Inc <br />
