Worlung To Restore Nature <br /> o Drilled three soil borings, north, east and south of the former tank location at the Van <br /> Buren Street property to further define the extent of soil contamination (Figure 2), <br /> O Collected two to three soil samples for analysts from each boring Analyzed the collected <br /> i samples for BTEX and TPHg, <br /> i <br /> ' O Collected a hydropunch water sample from each boring to provide additional groundwater <br /> analytical data, analyzing the collected samples for BTEX and TPHg <br /> ' Methodology <br /> RESNA drilled five soil borings, two of which were completed as groundwater monitoring <br /> wells The borings were drilled by Spectrum Exploration, Inc , license no 512268, using a <br /> hollow stem auger ng A field geologist was present to log all drill cuttings and soil samples <br /> utilizing the Unified Soil Classification System Descriptions of soil types encountered, sample <br /> collection intervals and well construction details are recorded on boring/well logs and included <br /> in Appendix 1. <br /> i <br /> ' Two borings were advanced to approximately 42 feet below surface grade, 15 feet below the <br /> water table and completed as groundwater monitoring wells (MW-8 and MW-9) Cored soil <br /> samples were collected for lithologic description above the water table at 5-foot intervals and <br /> below the water table at selected intervals in accordance with RESNA's Soil Sampling Protocol <br /> ' (RESNA, May 4, 1994, Workplan for Additional Site Investigation, Appendix I) Two soil <br /> samples were collected for laboratory analysis from each of these borings one sample was <br /> ' collected from areas where physical evidence indicated contamination or at depths where impact <br /> was previously noted, and the second sample was collected from the capillary fringe sods, <br /> ' approximately 26 feet below surface grade The locations of the wells are shown on Figure 2 <br /> 1 <br /> 15oo iowmPOATSI.SR-06%F NL 7 <br />
