| Short description: |
A field study was performed to evaluate indoor air concentrations and vapor intrusion (VI) of tetrachloroethylene (PCE) and other chlorinated solvents at a commercial retail site in Dallas, TX.
VI often is the dominant pathway in risk assessments for sites with petroleum fuels or chlorinated solvents. Dry cleaning establishments are a common type of VI site, but no studies at such sites are found in the literature. This paper presents the results of an unusually comprehensive site investigation at a former dry cleaning establishment, and the results offer important insights into two issues of intense debate among practitioners: whether external soilgas data are representative of subslab soil gas and what a lower bound attenuation factor is,
