SESOIL Output <br /> The SESOIL model was run for 99 years (the maximum duration allowed by the model) for <br /> tetradecane. SESOIL provides a detailed output for every month and a summary for each <br /> year of the simulation The model estimates the partitioning of the chemical in each layer <br /> between the soil-gas, soil-moisture, adsorbed fraction on soil particles, and a pure phase if <br /> leachate loading exceeds the aqueous solubility of the chemical The model provides <br /> information on the mass of chemical in each layer as well as the total mass of chemical that <br /> exits the soil column and is predicted to enter the groundwater A printout of input files <br /> and key output years from the SESOIL model are presented in APPENDIX B <br /> Tetradecane, representing petroleum hydrocarbons at the site, was conservatively predicted <br /> to migrate through the soil column less than one foot to an actual depth of less than 41 feet <br /> bgs Therefore, the model predicts that the petroleum hydrocarbons will not reach <br /> groundwater, currently at 55 feet bgs <br /> 4.5 Exposure Assessment Summary <br /> Each of the three potential exposure pathways, direct contact,vapor inhalation, and ingested <br /> groundwater, has been shown to be incomplete, therefore, there is no site-related exposure <br /> to petroleum hydrocarbons <br /> G U=1TSNrrAFE FNL\k"as 2693 4-15 ch=Ri.P 1%3 <br />
