k'■ K L E I N F E L D E R <br />5 ANALYTICAL RESULTS <br />5.1 SOIL SAMPLING RESULTS <br />The three soil borings were drilled on May 28, 2002. The locations of MW -1 and MW -3 were <br />chosen to assess downgradient groundwater and soil conditions of the former reported leaking <br />hydraulic lift located in the service garage area. The MW -2 location was chosen to assess the <br />groundwater and soil conditions upgradient of the service garage area. The soils encountered <br />ranged from sand to silty sand, and clay. No unusual odors or soil discoloration were noted from <br />the soil cuttings. First encountered groundwater was noted at a depth of approximately 20 feet bgs. <br />Eighteen (18) soil samples were collected from the three soil borings drilled for the installation <br />of the monitoring wells. A total of two soil samples collected from each soil boring were <br />analyzed. The results for the soil samples collected for laboratory analyses are presented in Table <br />2. <br />TABLE 2 <br />SUMMARY OF SOIL ANALYTICAL RESULTS <br />Sample Location <br />MW -1 <br />MW -2 <br />MW -3 <br />Units <br />Date Sampled <br />Sample Depth (bgs) <br />Sample ID Number <br />5/20/02 <br />10' <br />25228 <br />5/20/02 <br />15' <br />25229 <br />5/20/02 <br />10' <br />25234 <br />5/20/02 <br />15' <br />25235 <br />5/20/02 <br />to, <br />25240 <br />5/20/02 <br />15' <br />25241 <br />TPH-g <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Benzene <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Toluene <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Eth lbenzene <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Xylene <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />MTBE <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />DIPE <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />ETBE <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />TAME <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Methanol <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />mg/kg <br />Fuel Fingerprint <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />m <br />mg/kg = milligrams per kilogram <br />bgs = below ground surface <br />ND = analyte not detected above the laboratory reporting limit <br />20-3978-03.CHEV / ST02RI I I Page 11 of 18 <br />Copyright 2002, Kleinfelder, Inc.
