Performance of Two Technologies to Control Difficult-to-Treat Matrix Diffusion Zones: Post-Bioremediation Sustained Treatment and MNA in Low Permeability Units
Abstract
In-situ bioremediation (ISB) and monitored natural attenuation (MNA) are two widely used approaches to treat and control persistent matrix diffusion sources at chlorinated solvent sites. Such source zones represent a significant liability to the Department of Defense (DoD). Research has suggested that processes may be active at both ISB and MNA sites that could provide additional benefits to their application near or within low-permeability (lowK) matrix diffusion zones. The objectives of the project were: i) to develop new process knowledge on how to measure and demonstrate sustained treatment following application of ISBand ii) to evaluate and quantify MNA processes in low-K matrix diffusion zones. Data from field demonstrations and data mining of other sites indicated the occurrence of these processes and provided useful information on quantifying and assessing these processes. Fact Sheets are provided to allow cost effective application of these concepts at other sites using existing site data.
