Misawa Air Base, Japan, has an ongoing investigative effort to characterize the extent of petroleum soil contamination related to Tank Farm 2. During the period or 18 to 19 August 1998, soil and water samples were collected through a collaborative effort between the base, Air Force Center of Environmental Excellence and the Environmental Protection...

This paper presents a quantitative method for the risk-based evaluation of Total Petroleum Hydrocarbons (TPH) in vapor intrusion investigations. Vapors from petroleum fuels are characterized by a complex mixture of aliphatic and, to a lesser extent, aromatic compounds. These compounds can be measured and described in terms of TPH carbon ranges. Tox...
The US Environmental Protection Agency Office of Underground Storage Tanks (US EPA OUST) and Interstate Technology and Regulatory Council (ITRC) have recently published guidance indicating that buildings separated from light non-aqueous phase liquid (LNAPL) sources by more than 15 ft (4.6 m) are not a concern for vapour intrusion at petroleum under...
Subsurface sources of petroleum hydrocarbons emanating from leaking underground storage tank (LUST) systems typically do not result in the intrusion of associated vapors into overlying buildings. However, under certain circumstances, this type of vapor intrusion can occur. To better understand the conditions under which vapor intrusion may or may n...

Total 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 (TPHCWG) 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 known human carcinogen, is likely to be present at concentrations high enough to dominate cleanup decisions.
