' Report-Soil and Groundwater Investigation <br /> Herman&Helen's Marina <br /> September 26,1995 <br /> ' Page-5- <br /> rinsed with hydrocarbon-free water. The Hydropunch II was lowered to the bottom of the boring, <br /> ' just above the water table, and pushed approximately 4 feet ahead of the augers. The rod was then <br /> withdrawn to expose approximately 3.5 feet of the PVC screen so that groundwater entered the <br /> ' sampling chamber. <br /> ' A Teflon bailer was lowered into the sampling chamber and a groundwater sample was <br /> collected. The bailer sample was inspected for free product, petroleum odor, and sheen. The <br /> ' sample was gently poured into two (2) 40-m1 glass volatile organic analyses (VOA) vials, and one (1) <br /> 1-liter amber glass bottle. The sample containers were sealed, labeled, and placed in a cooler chilled <br /> ' with ice for delivery under chain-of-custody procedures to GeoAnalytical Laboratories, in Modesto, <br /> California for analysis. <br /> ' 3.5 Laboratory Analysis <br /> ' The soil and groundwater samples collected for chemical analysis were analyzed for benzene, <br /> toluene, ethyl benzene, and total xylenes (BTEX) by EPA Method 8020 (602 for water), for total <br /> petroleum hydrocarbons quantified as gasoline (TPH-G) by Method 5030/LUFT, and for total <br /> ' extractable petroleum hydrocarbons, quantified as diesel, motor oil, and kerosene (TEPH) by Method <br /> 3015/LUFT. The results of the soil and groundwater analyses are presented in Sections 3.5.1 and <br /> 3.5.2, below. <br /> ' 3.5.1 Laboratory Results - Soil <br /> Three (3) soil samples (1 sarnple per borehole) were retained for laboratory analysis. Each <br /> ' sample was labeled according to the specific project number, the borehole number, and the depth at <br /> which the sample was collected. <br /> ' The laboratory analyses indicate concentrations of TPH-G and BTEX in the soil samples <br /> ' analyzed from each borehole. BTEX concentrations were detected ranging from 5.2 Ilg/kg to 22,000 <br /> µg/kg. TPH-G concentrations were detected in the soil at concentrations ranging from 7.5 mg/kg to <br /> ' 300 mg/kg. TEPH (diesel) concentrations were detected in HP-3 at 16 mg/kg and in HP-1 at 190 <br /> mg/kg. The results of the soil analyses are shown in Table 1, below. Laboratory report sheets <br /> ' indicating analytical methods used, detection limits, and results of analyses are located in Appendix C. <br /> n *%� <br /> ' L� CONDOR <br />
