24 December 2014 <br />AGE Project No. 14-3154 <br />Page 2 of 7 <br /> <br />Advanced GeoEnvironmental Inc. <br /> <br />On 05 December 2014, eight soil borings (AB8 through AB16) were advanced within an <br />area of the property were former glass debris and dust waste streams were historically <br />managed/treated, stored and on the surface disposed. One soil boring was advanced at <br />eastern edge of the southern parcel near depression which was depicted to have <br />surface water discharged. Several borings were also advanced near the former surface <br />sewer discharge areas, east of the glass storage area. <br /> <br /> On 08 December 2014, five soil borings (AB17 through AB21) were advanced within an <br />area of the property were former glass debris and dust waste streams were historically <br />managed/treated, stored and on the surface disposed. <br /> <br />Samples were collected utilizing a Borings were advanced utilizing an AMS <br />Powerprobe 9600 direct push drilling rig equipped with 1.25-inch diameter probing rods. <br />or van-mounted, Geoprobe® 5400 direct-push probing unit equipped with 1.25-inch <br />diameter probing rods. Soil borings B1, B2 and B3 were advanced in the northwest, <br />northeast and middle sections of the building, respectively. Soil borings B4 and B5 were <br />located outside the building near the southwest and southeast outer corners of the <br />building, respectively. The direct-push probing unit advanced soil borings B1 through B5 <br />using a hydraulic hammer to drive sampling tools to specified depths. <br /> <br />All borings were advanced to a depth of 15 feet below surface grade (bsg). Borings <br />AB1, AB2, AB3 were advanced to a depth of 25 feet bsg; Borings AB6 through AB8, <br />AB10, AB12 and AB16 were advanced to a depth of 20 feet bsg; for collection of soil <br />samples. Soil boring locations are illustrated in Figure 2. <br /> <br />Prior to sample collection, equipment was thoroughly rinsed with clean water after being <br />washed with a solution of Alconox. Probing rods and drilling equipment were thoroughly <br />cleaned prior to soil probe boring advancement. <br /> <br /> <br />2.1. SOIL SAMPLE COLLECTION <br /> <br />Soil samples were collected at five foot minimum intervals from boring, using a 1.5-inch <br />diameter Geoprobe soil sampling assembly loaded with one two-foot long acetate <br />sleeve. After sample collection, a portion of the acetate sleeve was separated and the <br />ends were covered with Teflon sheets, capped and sealed with tape. Sample sleeves <br />were labeled with soil boring location, depth, time, date and sampler's initials and then <br />placed in a chilled container. <br /> <br />Soil sample duplicates were extruded into plastic bags and field-screened for the <br />presence of organic vapors using an organic vapor meter (OVM), equipped with a <br />photo-ionization detector (PID). Additionally, the soil was visually classified in <br />accordance with the Unified Soil Classification System (USCS). Soil boring logs are <br />included in this report (Appendix A). <br />
