Di Salva Tmek Lines-SIR ya, March 9,1995 Page-4- terephthalate liner. Following collection of the core sample, the liner was removed from the coring r. tool and one soil sample was collected from the linear at the selected interval using a 1-inch diameter, clean, brass sleeve. Soil samples were collected from SP2, SP3 and SP4 at 6 feet and 12 feet bgs. i. Following soil sample collection, the brass sleeve was prepared for shipment to the laboratory. The remainder of the core sample was used for geological logging and screened in the field with a Photo Ionization Detector (PID). The PID is accurate from a range of approximately 1 part per million (ppm) to 2,000 ppm total hydrocarbon gases. L Each soil sample collected for laboratory analyses was sealed at both ends with Teflon tape, 6W capped, wrapped with duct tape, and labeled. All soil samples were stored for shipment in a cooler chilled with real ice and delivered under chain-of-custody procedures to GeoAnalytical Laboratories, Inc., located in Modesto, California. The core soil samples collected from the subsurface were logged using the Unified Soil Classification System by a geologist working under the supervision of a Californian registered engineer. The geological logs include field observations such as soil type and color, estimated moisture content, presence of petroleum odor and field PID measurements. The soil L logs for SPI through SP4 are contained in Appendix B. The soil and materials generated during continuous coring and the cleaning effluent were place in a 55-gallon D.O.T. drum and left on site. L Disposal of hazardous materials, if any, will be the responsibility of Di Salvo Truck Lines. `a 3.2 Sample Collection - Groundwater Following collection of the soil sample from the capillary zone at a depth of approximately 12 feet bgs, the continuous coring tool was driven to a total depth of approximately 16 feet bgs. The coring tool was removed from the soil probe and groundwater was allowed to stabilize. The sidewalls in each soil probe collapsed beneath the capillary zone and, as a result, the final depth of each soil hip probe was approximately 13.5 feet bgs. Groundwater stabilized in each soil probe at a depth of L approximately 12 feet bgs. LTo collect a groundwater sample, a disposable, polyethylene bailer was lowered into each 2- inch diameter soil probe and allowed to fill with groundwater. The rate of groundwater recharge into { SPI, SP2, and SP4 permitted the collection of only one liter of water plus the VOA samples.
