In situ anaerobic transformation of trichlorofluoroethene in trichloroethene-contaminated groundwater.
Methods are needed to obtain in situ information on the transformation rates of trichloroethene (TCE), the most commonly detected organic groundwater contaminant. The objective of this research was to investigate the potential for determining TCE transformation rates in groundwater by measuring the transformation rate of its fluorinated surrogate, trichlorofluoroethene (TCFE). To explore this h...
متن کاملQuantifying the effects of fumarate on in situ reductive dechlorination rates.
In situ methods are needed to evaluate the effectiveness of chemical amendments at enhancing reductive dechlorination rates in groundwater that is contaminated with the priority pollutant, trichloroethene (TCE). In this communication, a method that utilizes single-well, "push-pull" tests to quantify the effects of chemical amendments on in situ reductive dechlorination rates is presented and de...
متن کاملAnaerobic reductive dechlorination of 1-chloro-1-fluoroethene to track the transformation of vinyl chloride.
1-Chloro-1-fluoroethene (1,1-CFE) was studied as a reactive tracer to quantify the anaerobic transformation of vinyl chloride (VC). Batch kinetic studies of 1,1-CFE and VC transformation were performed with an enrichment culture obtained from the Evanite site in Corvallis, OR. The culture is capable of completely transforming trichloroethene (TCE) through cis-dichloroethene (c-DCE) and VC to et...
متن کاملAnaerobic Biodegradation of RDX and TCE: Single- and Dual-Contaminant Batch Tests
Several sites in the United States have groundwater contaminated with mixtures of high explosives and chlorinated solvents. This research examined the ability of two microbial cultures (anaerobic sludge and a facultative enrichment culture) to biodegrade singleand dual-contaminant mixtures of trichloroethene (TCE) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) under anaerobic conditions. In ...
متن کامل"Forced mass balance" technique for estimating in situ transformation rates of sorbing solutes in groundwater.
A method for estimating in situ transformation rates of sorbing solutes in groundwater is presented. The method utilizes a novel data processing technique called "forced mass balance" (FMB) to remove the effects of transport processes from reactant and product concentrations measured during single-well, "push-pull" tests. The effectiveness of the FMB technique was evaluated by quantifying error...
