The ends covered with aluminum foil, plastic caps and <br /> sealed, labeled and placed on blue ice ;�in an ice chest for I <br /> transport to a state certified analytical laboratory with the <br /> chain-of-custody. <br /> } <br /> E <br /> LABORATORY ANALYSES: <br /> I� <br /> The soil samples (1 and 2) were analyzed for Total Petroleum <br /> i <br /> Hydrocarbons as Gasoline (TPHg) , Benzene, Toluene, Ethylbenzene, <br /> Xylene (BTEX) and EPA Methods 7420/7421 and8240. Soil Samples (3 k <br /> f ! <br /> and 4 ) were analyzed for Total Petroleum Hydrocarbons as Diesel <br /> (TPHd) and BTEX. <br /> The results of analysis of the soil samples�lcollected are shown in <br /> Table 1. The locations of the soil samples taken from the i <br /> excavation are shown on the site plan (Figure 1) . The laboratory <br /> testing results by Anametrix, Inc. with chain-of-custody is <br /> iF <br /> attached. <br /> r <br /> FINDINGS: 't <br /> TPHg for sample 1 is 290 milligram per kilogram (mg/kg) , Benzene <br /> and Toluene are (non-detectable) , Ethylbenzene (1.6 mg/kg) , and <br /> SOIL TECH ENGINEERING, INC. <br /> {P Ik <br /> t <br /> 2 I <br /> it <br />
