The rig equipment and augers were steam cleaned before and after the drilling of each borehole Sampling equipment was washed xNith a solution of TSP and rinsed in clean water between each sampling interval SOIL SAMPLE PRESERVATION The soil samples were preserved by covering the brass sample sleeve ends with a teflon liner and then sealing the teflon covered ends with plastic caps Each sleeve was labeled with the site name, date, time, sample location, and analyses to be performed Each labeled soil sample was placed in a separate zip lock bag, deposited in an ice chest, and cooled to 4°C The samples and accompanying cliain-of-custody documentation were deliver ed to Kiff Analytical Laboratories {DHS 92236) on June 15, 2001 SELECTION AND CERTIFIED LABORATORY ANALYSES OF SOIL SAMPLES The three soil samples collected from MW4 at 10, 15, and 20 feet bgs were analyzed by Kiff Analytical Laboratories for concentrations of TPH-G BTEX and MTBE using, EPA method 8260B RESULTS OF CERTIFIED LABORATORY ANALYSES OF SOIL SAMPLES The results of the certified analyses of soil samples collected on June 12, 2001 are shown . in Table 2 Copies of the laboratory reports are included as Appendix C of this report TPH-G concentrations were 7,000 nig/kg, 2,400 mg/kg, and 93 mg/kg at the 10, 15 and 20 foot depth intervals respectively MTBE was not detected any of the three samples DISPOSITION OF SOIL CUTTINGS AND WASTE WATER The didling of MW4 generated approximately one cubic yard of soil cuttings The soil cuttings were stockpiled on-site with a covering and base of 6-m►1 polyethylene sheeting A WEGE geologist collected one composite soil samples from four locations within the soil pile on June 19, 2001 The soil sample was labeled and preserved as described above The composite sample was analyzed by Kiff for concentrations of TPH-G, BTEX and MTBE using EPA method 8260B and lead using EPA method 6010 The analytical results will be used to profile the soil for disposal at an appropijate landfill facility Rinse water from the washing of the augers and sampling equipment was stored on-site in labeled 17H 55 gallon DOT approved drums The rinse water will be transported to the M P Environmental recycling facility under a non-hazardous waste manifest along with the wastewater generated by quarterly groundwater monitoring following the next quarterly monitoring round 4 Ai c Pump QM 4-6, 2001
