The properties of ethylbenzene were obtained from a file internal to SESOIL and were the same for <br /> all simulations The climatic data was obtained from a current California data file internal to <br /> SESOIL and were the same for all simulations The climatic data is from a Stockton observation <br /> point <br /> i <br /> An extract of the output from each of the three simulations is contained in Appendix A through C <br /> The depth of maximum contaminant transport in Run 1 (realistic case) is 1594 cm, short of the top <br /> of the saturated zone No increase in the concentration of dissolved ethylbenzene in ground water <br /> resulted from the simulated transport of Run 1 Contaminant transport in Run 2 (worst case) <br /> occurred to the saturated zone, with an indicated increase in concentration of dissolved <br /> ethylbenzene in ground water The depth of maximum contaminant transport in Run 3 (best case) <br /> is 1260 cm, short of the top of the saturated zone No increase in the concentration of dissolved <br /> ethylbenzene in ground water resulted from the simulated transport of Run 3 <br /> I <br /> In summary, in a 10-year simulation, SESOIL calculations, using realistic parameter values, <br /> indicate that leaching of ethylbenzene to the saturated zone at 305 South Hutchins Street is <br /> unlikely Therefore, it would be unlikely to expect ethylbenzene concentrations in ground water to <br /> increase because of transport from the unsaturated zone This leads to the conclusion that leaching <br /> of other fuel hydrocarbons to the saturated zone from the vadose zone beneath the 305 South <br /> Hutchins Street site is not likely <br /> I <br /> ll <br />
