' 30 January 2015 AGE Project No. 14-3154 ' Page 2 of 6 2.0. SOIL PROBE BORING ADVANCEMENT ' On 04 December 2014, seven soil borings (AB1 through AB7) were advanced near the 1985 straw oil line leak and 1992 fuel oil leak from an AST, south of the electrical ' transformer station and west of the station. On 05 December 2014, nine soil borings (AB8 through AB16) were advanced within an ' area of the property were former glass debris and dust waste streams were historically managed/treated, stored and disposed on the surface. One soil boring was advanced at ' the eastern edge of the southern parcel near a depression which was depicted to have surface water discharged. Several borings were also advanced near the former surface sewer discharge areas, east of the glass storage area. ' On 08 December 2014, five soil borings (A617 through AB21) were advanced within an area of the property were former glass debris and dust waste streams were historically ' managed/treated, stored and disposed on the surface. Borings were advanced utilizing an AMS Powerprobe 9600 direct push drilling rig ' equipped with 1.25-inch diameter probing rods. Samples were collected utilizing a Geoprobe soil sampling tool and one two-foot long acetate sleeve. ' The majority of the soil borings were advanced to depths of 15 feet below surface grade (bsg). However, borings AB1, AB2, AB3 were advanced to depths of 25 feet bsg; and borings AB6 through AB8, A1310, AB12 and AB16 were advanced to depths of 20 feet ' bsg. Soil boring locations are illustrated in Figure 2. Prior to sample collection, equipment was thoroughly rinsed with clean water after being ' washed with a solution of Alconox. Probing rods and drilling equipment were thoroughly cleaned prior to soil probe boring advancement. ' 2.1. SOIL SAMPLE COLLECTION ' Soil samples were collected at a minimum of five foot intervals from the soil borings using a 1.45-inch diameter Geoprobe soil sampling assembly loaded with one two-foot long acetate sleeve. After sample collection, a portion of the acetate sleeve was ' separated and the ends were covered with Teflon sheets, capped and sealed with tape. Sample sleeves were labeled with soil boring location, depth, time, date and sampler's initials and then placed in a chilled container. ' Soil sample duplicates were extruded into plastic bags and field-screened for the presence of organic vapors using an organic vapor meter (OVM), equipped with a ' photo-ionization detector (PID). Additionally, the soil was visually classified in accordance with the Unified Soil Classification System (USCS). Soil boring logs are included in this report (Appendix A).
