1 <br /> 3.0 Site Investigation Results <br /> ' 3.1 Subsurface Investigation <br /> 3.1.1 Soil Sample Results <br /> 1 The soil samples analyzed during this site investigation from the soil borings were not reported <br /> to contain TPHg, TPHd, or TPHo at concentrations exceeding the analytical method reporting <br /> limits. In addition, volatile organic compounds benzene, toluene, ethylbenzene, and xylenes <br /> (BTEX), and methyl-tert-butyl-ether(MTBE)were not reported at concentrations exceeding the <br /> analytical method reporting limits (Tables 1 and 2). Organic lead was not reported at <br /> concentrations exceeding the analytical method reporting limits. In the five samples analyzed, <br /> pH ranged from 7.8 to 8.7. <br /> ' 3.1.2 Groundwater Grab Sample Results <br /> Groundwater grab samples from the two hollow stem auger soil borings were not reported to <br /> contain TPHg, BTEX, or MTBE at concentrations in excess of the analytical method reporting <br /> limits (Table 3). TPHd and TPHo were detected in two groundwater grab samples at the <br /> ' following concentrations. <br /> SR 120-HS 1: 110 µg/1 TPHd and 86 ug/l TPHo. <br /> ' • SR 120-HS2: 130 µg/1 TPHd and 100 ug/1 TPHo. <br /> ' -IMCRFPACOMMOMSKD9200MR.MJ&8M347802m..dx 3-1 <br />
