Characterization of trichloroethylene contamination in the fractured bedrock at the Smithville site / by A. Brown [and seven others]. : En13-5/97-140E-PDF
"This study has examined trichloroethylene (TCE) contamination and groundwater geochemistry of the bedrock units underlying the CWML site in Smithville. Two approaches were developed to measure the concentration of TCE discrete fractures, and to examine-the extent of contamination in the deeper rock units. The first approach used a small, 0.1 m sampling interval and a down-hole pneumatic pump to isolate and sample single discrete features, using existing transmissivity data to guide fracture location. The second approach focused on building a borehole concentration profile, using a larger submersible pump with a 1.5 m sampling interval. Geochemistry results, including anions, cations and dissolved oxygen, were obtained from most of the 0.1 m zones isolated. Trichloroethylene concentration, Eh, pH, TCE biodegradation products and trichlorobenzenes were all sampled for from the discrete features and larger zones"--Executive summary, page i.
