A former underground storage tank site at Scott Air Force Base, Illinois, was selected for a field demonstration of the Total Petroleum Hydrocarbon Criteria Working Group approach. Soil at the site was impacted by a release of JP-8 jet fuel. The Working Group approach assesses total petroleum hydrocarbon (TPH) mixtures in 13 fate and transport fractions and applies best available toxicity criteria to each of the fractions to develop Risk Based Screening Levels (RBSLs). TPH levels detected at the site were very low. The majority of the released JP-8 had been previously excavated during removal of the tanks. With the exception of the volatilization to indoor air pathway, the findings of this risk assessment suggest no further action is necessary. Due to the extremely low levels of volatile organic carbon detected and the fact that there is currently no structure on the site, volatilization to indoor air is not a complete pathway, nor likely to be. The RBSLs developed from the Working Group approach for this site were especially suitable due to the lack of carcinogenic benzene or polycyclic aromatic hydrocarbons detected.
