SOIL BORING ADVANCEMENT <br />A total of four (4) borings will be advanced in northwest area of the site around the <br />former underground and waste oil tanks. A total of three (3) soil borings will be <br />advanced in the southeastern portion of the site around well MW-5 (Figure 2). All <br />borings will be advanced utilizing a van-mounted direct push drilling rig equipped with <br />1.5-inch probing rods. All borings will be advanced to a total depth of ten feet below <br />surface grade for collection of soil samples. <br />Soil samples will be collected from all borings at five-foot intervals at 5 and 10 feet bsg. <br />However, field personnel may adjust the frequency and method of sampling in <br />consultation with an AGE Professional Geologist. <br />Soil samples surrounding the former northwestern tank and in the area surrounding well <br />MW-5 will be analyzed for: <br />Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g and <br />TPH-d) by EPA method 8015B; and <br />Full scan volatile organic compounds (VOC's) in accordance with EPA method <br />8260B; <br />Soil samples surrounding the former waste oil tank will be analyzed for: <br />TPH-g and TPH-d by EPA method 8015B; <br />Total oil and grease by EPA method 1664; <br />VOC's in accordance with EPA method 8260B; <br />Semi-volatile organic compounds by EPA method 8270; <br />Polychlorinated biphenyls (PCBs) by EPA method 8080; and <br />Title 22 metals by EPA method 200.7. <br />Laboratory reports for groundwater analysis, testing methods and laboratory quality <br />assurance/quality control (QA/QC), and sample chain of custody documentation will be <br />presented in a report with findings and recommendations.
