AGE-NC-07-1517 17 March 2008 Page 3 of 7 Soil samples BNEWSN and BNEWSS were collected from approximately one foot bsg from the west sidewall of the northeast excavation area, which was extended on 01 February 2008. Soil samples SES 1 through SES3 were collected at approximately one foot bsg from the east sidewall north, middle and south sections of the southeast excavation area. Soil sample SEB was collected from approximately 2 feet bsg from the center floor of the southeast excavation area at the location of former sampling point CC. Following sample collection, each sleeve end was covered with a teflon sheet, capped and sealed with tape to preserve the sample. The sample sleeve was labeled with the boring location, depth, time,date and sampler's initials.Appropriately sealed and labeled samples were placed in a chilled container under ice and transported under chain-of-custody procedure to a Cal Tech Environmental Laboratory of Paramount, California, a California Department of Public Health (CDPH)-certified laboratory. Selected soil samples were analyzed for the following constituents: • Total Petroleum Hydrocarbons quantified as gasoline (TPH-g) and diesel (TPH-d) by USEPA Method 8015 Modified; • Full list of Volatile Organic Compounds (VOCs)by USEPA Method 8260; • LUFT Metals by USEPA Method 6010B; • Lead with soluble threshold limit concentration(STLC)by USEPA Method Wet Extraction USEPA Method 6010B; • Lead with total threshold limit concentration(TTLC)by USEPA Method 6010B/1311 and • Semi-Volatile Organic Compounds by USEPA Method 8270 (selected stockpile samples only). Soil sample locations are depicted on Figure 4. 2.2.3. Backfilling Backfilling was not performed at the time of publication of this report. 2.2.4.
