DATES COVERED (From -To) SUPPLEMENTARY NOTES ABSTRACTTotal petroleum hydrocarbon (TPH) fractional analysis and tiered risk assessments at petroleum release sites are replacing cleanup approaches based upon total TPH concentrations. Field demonstrations of the Total Petroleum Hydrocarbon Criteria Working Group (TPHSWG) approach for assessing human health risk at petroleum release sites were performed at eight Department of Defense installations. One site also provided an opportunity to demonstrate the Massachusetts Department of environmental Protection methodology and compare the approaches. Two lessons learned from the field demonstrations were: (1) TPH fractional analysis approaches provide a scientific bases for assessing risk and implementing appropriate criteria alone; and (2) the TPHCWG approach should not be used at relatively "fresh" petroleum product release sites because benzene, a know human carcinogen, is likely to be present at concentrations high enough to dominate cleanup decisions. d u ctio n ............................................................................................................................ This report summarizes the results of a series of field demonstrations that were performed at seven Department of Defense installations in the United States and one Air Force installation in Japan using the TPHCWG methodology. The field demonstrations were conducted at Misawa Air Base, Japan; El Toro Marine Air Station, CA; Tinker AFB, OK; Scott AFB, IL; WrightPatterson AFB, OH; Elmendorf AFB, AK; Dobbins AFB, GA; and the Springfield Air National Guard Base (SANGB), OH. All eight field demonstrations were conducted between August 1998 and December 2002. Four of the demonstration sites were contaminated with jet fuel (i.e., JP-4, JP-5 or JP-8). The Misawa Air Base site was contaminated with a mixture of JP-4, JP-8, gasoline and diesel fuel. The Elmendorf AFB site was contaminated with diesel fuel, the El Toro site with both diesel fuel and heating oil, and the Tinker AFB site with JP-4 and diesel...
