USTs was noted. An electric power line which runs between the light poles on the property was also noted (Figure 2). DRILLING AND SOIL SAMPLE COLLECTION On March 26, 2012, three (3) soil borings (SBI, SB2, and SB3) were advance on the property (Figure 2). The borings were advanced by Cascade Drilling of Sacramento, California using a truck-mounted direct-push drilling rig. The rig was a model 6600 direct-push rig. The borings were advanced to depths between 20 and 46 feet below ground surface (bgs). • Boring SB1 was advanced at the location of the eastern area of soil disturbance as noted during the geophysical survey. • Boring SB2 was advanced at the location of the western area of soil disturbance. • Boring SB3 was advanced to the northwest of the areas of soil disturbance. The borings were advanced using direct-push rods and samples were collected by advancing the rods with acetate sample liners in approximately 2- to 4-foot intervals. After each interval, the core was retrieved, core barrel disassembled, and the sample liner was removed and transferred to the onsite geologist. The soil borings were logged using the Unified Soil Classification System. A photo ionization detector (PID) was used to screen soil samples in the field and the PID readings for each sample were included on the boring logs (Appendix Q. Down-hole equipment was decontaminated using a triple rinse system containing detergent. Waste generated was drummed, sealed, labeled and left onsite. GROUNDWATER SAMPLE COLLECTION On March 26, 2012, attempts were made to sample groundwater from boring SB1. A layer of very moist silt was noted in at between 36 to 37.5 feet bgs in boring SB1. Drilling continued to 46 feet bgs when the rods were removed and groundwater was allowed to enter the boring. Groundwater was collected using temporary PVC casing inserted into the borehole and collected using tubing and a check valve connected to the bottom of the tubing. Groundwater sampling was not planned for borings SB2 and SB3 and no groundwater was encountered or sampled from those borings. BORING DESTRUCTION Following completion of sample collection and removal of tooling, the borings were backfilled with neat cement grout as required by the permitting agency SJCEHD and completed at the surface with concrete to match the surrounding conditions. An inspector from the SJCEHD was onsite to witness the grouting. LABORATORY ANALYSIS The soil and groundwater samples were labeled and placed into a cooler with ice following sampling. All of the samples were transferred under appropriate chain-of-custody Project No. 305662 AE1 April 4, 2012 Page 3 of 6
