This paper reports the results and interpretation of a detailed experimental investigationof the physical and biological factors affecting gasoline vapor transport from contaminated soils intoa building.

The study was conducted at the site of a former gasoline station located at the Alameda Naval AirStation (ANAS), California (see Figure 1). In 1980, one of three 45-m3 undergroundstorage tanks was damaged. The tank was drained and repaired between 1980 and 1987. Subsequenttests revealed that subsurface leakage continued to be a problem, and in 1990 fuel was removedand . . .
