Abstract

With the advent of risk-based decision-making at petroleum and other chemical-release sites, screening-level models for the subsurface vapor-to-indoor air pathway are being used to identify scenarios for which there might be significant adverse impacts; determining when site-specific assessment is necessary; and development of target soil and groundwater screening levels. Objective comparison of the strengths and weaknesses of the various approaches and screening models has been difficult because of the scarcity of data and experience. One such data set comes from the Colorado Department of Transportation Materials Testing Laboratory Site in Denver, CO. This data set is of particular interest because of the large number (> 1000) of groundwater, soil gas, and indoor air concentration data.
