This study evaluated the effects of heterogeneous thermally altered carbonaceous matter (CM) on trichloroethylene (TCE) sorption for a low fraction organic carbon content (foc) alluvial sedimentary aquifer and aquitard system (foc=0.046-0.105%). The

Pump-and-treat (PT) remediation and associated concentration tailing are investigated at the field scale in a mildly heterogeneous sandy aquifer through the extraction of dissolved chlorinated solvent plumes that had developed over 475 d from a multi

Contaminant concentration ratios are used commonly to distinguish between different sources of contamination and to evaluate contaminant attenuation in groundwater, soil air, soil, and sediment. Logarithmic-scale correlation (log-log) plots provide s

The physical and chemical characteristics of NAPL (nonaqueous phase liquid) source zones in the subsurface present substantial challenges to the representativeness of soil samples collected for the purpose of characterizing the NAPL source. The princ

A chlorinated solvent mixture (2.0 L of trichloroethylene, 0.5 L of chloroform, and 2.5 L of tetrachloroethylene) was released into a sandy aquifer to create a heterogeneously distributed DNAPL (dense nonaqueous-phase liquid) source. The dissolution

Small-scale spatial variability of chemical concentrations in soil samples can introduce substantial uncertainty in the calculation of average concentrations and chemical mass in non-aqueous phase liquid (NAPL) source zones. Centimeter-scale sampling

This paper describes some of the results from a field experiment at the Canadian Forces Base Borden, Ontario, Canada. Five liters of a chlorinated solvent mixture (2.0 L of trichloroethylene, 0.5 L of chloroform, and 2.5 L of tetrachloroethylene) was

The low concentrations (ppm to ppb) typical of organic pollutants dissolved in groundwater have been a major factor limiting the application of stable isotope tracing techniques at contaminated field sites. In this study, pentane extraction of benzen
