No - 5095 P. 14 <br /> 19 March 2004 <br /> AGE-NC Project No. 02-0886 <br /> Page 3 of 8 <br /> grab ground water samples were collected from each boring. ` <br /> TPH as gasoline was reported in soil samples at concentrations ranging from non-detect (ND)to <br /> 1,800 parts per million(ppm);TPH as diesel was reported in soil samples at concentrations ranging <br /> from ND to 580 ppm. BTEX constituents were reported in soil samples at concentrations ranging <br /> from ND to 170 ppm.Although reported in one sample using EPA Method 8021,no MTBE or other <br /> fuel oxygenates wereereported in any of the samples selected for analysis using EPA Method <br /> 8260. re <br /> he <br /> TPH as gasoline,16TEX and MTBE were reported in each of the three grab ground water samples <br /> .. collected from the borings at concentrations ranging from 2.3 parts per billion(ppb)to 180 ppb.No <br /> TPH as diesel was reported in any of the grab ground water samples. The laboratory report and <br /> chains-of-custody are included as Appendix A. <br /> 3.0. SCOPE OF WORK <br /> y The scope of the work initially includes the advancement of one soil boring for completion as a <br /> ground water monitoring well. Based upon results of ground water samples collected from the <br /> monitoring well,two additional pilot borings maybe advanced for the installation of two additional <br /> monitoring wells. Upon installation, each well will be developed and sampled and, if necessary, <br /> placed into a quarterly ground water monitoring program. The scope of work will consist of the <br /> following tasks: <br /> e Permitting and pre-fieldwork activities; <br /> .. • Drilling and soil sample collection; <br /> • Monitoring well installation and development; <br /> e Ground water sampling and analysis; and <br /> • Report preparation. <br /> 3.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained from the EHD. In addition, an update to the <br /> health and safety plan presently on-file will be prepared in accordance with Occupational Safety and <br /> Health Guidance Manual for Hazardous Waste Site Activities(National Institute for Occupational <br /> Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, <br /> y 1985). Prior to mobilization, the proposed well locations will be clearly marked and a utility <br /> Advanced GeoEnvironmenul,Inc. <br /> r <br /> r <br />
