Remediation of PCE-contaminated Groundwater Using Permeable Reactive Barrier System with M0M-Bentonite

Abstract

The objectives of this research were to study the applicability and limitations of permeable reactive barrier (PRB) for the removal of tetrachloroethylene (PCE) from the groundwater. PRB column tests were conducted using reactive material with Moringa Oleifera Mass -Bentonite (Mom-Bentonite). Most of the PCE in the groundwater was degraded and/or captured (sorpted) in the zone containing activated material (MOM-Bentonite). The removal rate of PCE from the groundwater was 90% and 75% after 30 days and 180 days, respectively. The effect of micro-organisms on the long-term permeability and reactivity of the barrier is not well understood. MOM-Bentonite PRB system in this research has the potential to be developed into an environmentally and economically acceptable technology for the in situ remediation of PCE-contaminated groundwater.

Evaluation of Changes in the Permeability Characteristics of a Geotextile–Polynorbornene Liner for the Prevention of Pollutant Diffusion in Oil-Contaminated Soils

“…Ji and Cheong [30] applied PRBs as a method for remediating contaminated leachate from mines on-site and recommended the application of organic carbon mixtures as reactive media to remove high concentrations of aluminum. Furthermore, Chung and Lee [31] evaluated the suitability and limitations of Moringa oleifera mass bentonite (MOM-bentonite) as the reactive media of reactive barriers for treating aquifers contaminated by the movement of PCE-contaminated groundwater on site. Guerin et al [32] evaluated the applicability of PRBs for the remediation of groundwater contaminated with petroleum hydrocarbons.…”

A study on water quality change by land use change using HSPF

“…The riverine areas serve as important buffer zones that vertically and horizontally connect water ecosystems and wildlife ecosystems and are considered especially important in terms of the management of river ecological environments [8,9]. Riverine areas also play a significant role in maintaining the overall sizes of rivers and the adaptability of rivers to environmental changes, and have been reported as being important elements with respect to the hydrological river management practices associated with flood and drought control [10].…”

The Effect of the Mixture of Nonionic Surfactant and Bioactive Agent for Surfactant-enhanced Soil Flushing (SESF) of TCB Contaminated Soil

“…Dense non-aqueous phase liquids (DNAPLs), such as trichlorobenezene (TCB), have posed a threat to the environment in industrial areas of Korea (Lee et al, 2001;Chung and Lee, 2012). Under normal flow regimes, this DNAPL phase is immobile and often represents a long-term source of aquifer contamination as it slowly dissolves into the groundwater (Deshpande et al, 1999;Wang and Mulligan, 2004).…”
