Next Generation - Monitored Natural Attenuation And Enhanced Attenuation - Chlorinated Solvents

PDF Version Also Available for Download.

Description

Monitored Natural Attenuation (MNA) is a necessary part of the remedial action at most chlorinated solvent sites. As a result, site owners, stakeholders, and regulators are identifying and responding to MNAs technical challenges. For example, many contaminated plumes are not in anaerobic settings, making it unlikely the predominant mechanism embodied in existing protocols and guidance documents, reductive dechlorination, will be viable. This is the case for many of the chlorinated solvent sites at Department of Energy (DOE) facilities. The DOE is conducting a project to explore the possibility of other mechanisms contributing to the attenuation of chlorination solvents in the ... continued below

Description

Monitored Natural Attenuation (MNA) is a necessary part of the remedial action at most chlorinated solvent sites. As a result, site owners, stakeholders, and regulators are identifying and responding to MNAs technical challenges. For example, many contaminated plumes are not in anaerobic settings, making it unlikely the predominant mechanism embodied in existing protocols and guidance documents, reductive dechlorination, will be viable. This is the case for many of the chlorinated solvent sites at Department of Energy (DOE) facilities. The DOE is conducting a project to explore the possibility of other mechanisms contributing to the attenuation of chlorination solvents in the environment. The project is exploring three key areas: mass balance as a way to evaluate the significance of the different processes occurring at a site, sustainable enhancements as a way to increase the attenuation capacity of a site so that it is sustained allowing remediation goals to be met, and characterization and performance monitoring methods that will support the first two areas in a manner that will support transition to legacy management.
