It <br /> E r <br /> 4 <br /> f 2.4 Boring Logs is <br /> A detailed boring log was kept of the boring. SeeAppendix A. <br /> 2.6 Disposition of Soil Boring Cutting <br /> r L- <br /> Soil.cuttings were stockpiled until the results �o f the analysis were obtained. <br /> Il �. Disposition will follow along with the soil that will be excavated. <br /> 2,7 Soil Analyses <br /> IMM <br /> The soil samples were sealed and stored on ice until transported to a California- <br /> registered laboratory. Soil samples were analyzed f1or gasoline according to <br /> modified Method 8015. This methodspeciates and quantifies gasoline <br /> compounds by a solvent extraction of hydro11 carbons from the soil matrix, <br /> L injection of the solvent into the capillary column of a gas chromatograph, and <br /> flame ionization detection of hydrocarbons. Also; soil samples were analyzed for <br /> BTEX using method 8020. <br /> t <br /> 3.0 PRESENTATION OF RESULTS AND RECOMMENDATIONS <br /> Soil analysis results are indicated below in table 1. At a ,depth of 26.5 to 27 feet, it <br /> appears that the presence of gasoline is reduced.
