Woodward-Clyde V Soil samples were collected during Phase I and II using a "Probe-Drive Sampler" tool V developed by Geoprobe. The Probe-Drive Sampler is attached to the leading end of the probe rod and is driven into the subsurface. The threaded stop-pin in the trailing end of the sampler assembly prevents the piston tip and piston rod from sliding into the sample collection tube as the assembly is being driven to depth. At the desired sampling depth, the �— stop-pin, which is threaded into the drive head of the sampler assembly (lined with four 6- inch long by 1-inch diameter brass liners), is removed using extension rods inserted down the inside diameter of the probe rods. After the stop-pin has been removed, the sampler is again driven forward, soil is collected in the sample chamber as the piston retracts. The assembly is then brought back to the surface. The sample is prepared for chemical analysis V by placing Teflon sheeting and plastic end caps over the brass liner sections, labeling the sample with sample number, date, time, and project number, placing the sample in a resealable plastic bag, then placing the sample on ice in an ice chest until the samples were transported under chain of custody procedures to California Laboratory Services in Rancho Cordova, California, a California certified analytical laboratory. All samplers and probe rods were steam cleaned prior to use in each boring location. The samplers were decontaminated between each sample advancement using Alconox detergent wash, double tap water rinse, and double deionized water rinse. V Soil boring B-1 was advanced to a depth of 31 feet bgs located southeast of the former UST excavation in the vicinity of the former stockpile (Figure 4). Soil samples were collected at 3, 5, 10, 15, 19, 25, and 29 feet bgs. Soil samples for chemical analysis were collected from 4.5 to 5, 6.5 to 7, 11.5 to 12, 16 to 16.5, 19.5 to 20, 20 to 20.5, 25.5 to 26, and 30 to 30.5 feet bgs. No visible contamination, or elevated headspace readings were observed during the advancement of B-1. Soil boring B-2 was advanced to a depth of 31 feet bgs located northwest of the former UST excavation near an existing propane tank. Soil samples were collected at 5, 10, 15, 18, 20, 25, and 29 feet bgs. Soil samples for chemical analysis were collected from 16.5 to 17, 18.5 to 19, 19 to 19.5, 21.5 to 22, and 26 to 26.5 feet bgs. No visible contamination, or elevated headspace readings were observed during the advancement of B-2. V V 8054/FEMAWAXPIER.RFT/8-24-95 SAC 2-3 V
