! The samples were placed in an ice chest at four degrees centigrade and.transported under chain of <br /> custody to 1VIcCampbell Analytical (ELAP.1644) for analysis. Analysis for each sample consisted of <br /> total petroleum hydrocarbons as gasoline(TPHg) and total petroleum hydrocarbons as diesel (TPHd) <br /> by EPA method 8015; benzene, toluene, ethylbenzene, and xylenes(BTEX) by EPA method 8020; <br /> oxygenated fuel additives by EPA.method 8260; halogenated ;volatile organic compounds by EPA <br /> method 8260; polychlorinated biphenyls by EPA method 8080; LUFT metals by EPA method 6010 <br /> and hexavalent chromium by EPA method 7196. In addition, the sample from the soil stockpile was <br /> analyzed for semi-volatile organic compounds by EPA method 8270;and for.total oil.and grease(TOG) <br /> by EPA method 413.1. <br /> No detectable concentrations of any organic analytes were present in the`soil sample collected from <br /> beneath the UST. Metals in both samples were at naturally occurring background concentrations. The <br /> results from the sample collected from the soil pile showed slightly elevated levels of TPHg, TPHd and . <br /> TOG. However, the analytical-results from the sample taken beneath the former UST indicate that no <br /> significant impact had occurred. It appears that any contamination present in the vicinity of the tank <br /> was removed during the excavation. Analytical.-results are summarized in Table 1. Laboratory data. <br /> sheets are included in Attachment C. <br /> The stockpiled soil was`removed from the property and transported to the Forward Inc. landfill <br /> P P y p , <br /> for disposal.
