Abstract
A method for identifying and characterizing contaminated sources in a site having contaminated soils and sediments in which vapor pressure is measured at a plurality of subsurface soil sampling locations of the site, which measurements are then mapped, resulting in generation of a subsurface vapor pressure map. Contaminant mobility at the subsurface soil sampling locations having a peak vapor pressure is then determined and contaminants in fast release compartments and slow release compartments in the contaminated soils and sediments identified. Thereafter, the fraction of contaminants in the fast release compartments and the slow release compartments is determined. Calibration of the contaminant-specific vapor pressure with laboratory measurements of the rapid release fraction at each site allows a meaningful and rapid estimation of the spatial location and mass distribution of source areas.
