This document
provides a detailed report about a field study conducted by
EQM/URS on behalf of EPA's National Risk Management Research
Laboratory to characterize the subsurface contamination of
volatile organic compounds (VOCs) at a Brownfield commercial
site. The Triad approach was implemented to characterize the
extent of soil, groundwater, and soil gas contamination. These
data were used to assess impact on indoor air due to vapor
intrusion. Seventy-seven soil samples, twenty-eight groundwater
samples, and ten soil-gas samples were collected from
Geoprobe(TM) borings and analyzed on-site by USEPA Method SW-846
8265 direct sampling ion trap mass spectrometry (DSTIMS).
Additional SW-8260b and TO-15 analyses were performed on
approximately 10% of the samples by off-site laboratories.
Tetrachloroethylene (PCE), trichloroethylene (TCE) and
cis-1,2-dichloroethylene (DCE) were detected in all media with
PCE as the prevalent compound (September 2006, 86 pages).
