A CONTROLLED FIELD EVALUATION OF CONTINUOUS VS. PULSED PUMP-AND-TREAT REMEDIATION OF A VOC-CONTAMINATED AQUIFER : SITE CHARACTERIZATION, EXPERIMENTAL SETUP, AND OVERVIEW OF RESULTS

BROWN M. J. / MACKAY D. M. / WILSON R. D. / et al. - ARTICLE DE PERIODIQUE - 2000

Methods and results of the estimation of the pre-pumping and post pumping distributions and masses of volatile organic contaminants. Details of cell construction and locations of core collection and well installation. Sorption characteristics of the coarse sand and silty clay loam are investigated for PCE and TCE. Schematic of the extraction-injection tracing system used in each experimental cell is developped. Comparison between pulsed and continuous pumping results effects on the concentration evolution of VOC. Mass estimates by core sampling or multi-level technic. Discussion on the cumulative removal.
