Monitored Natural Attenuation (MNA) and Enhanced Passive Remediation (EPR) for chlorinated solvents
The Department of Energy (DOE) sponsored an initiative to facilitate efficient, effective and
responsible use of Monitored Natural Attenuation (MNA) and Enhanced Passive Remediation
(EPR) for chlorinated solvents. This Office of Environmental Management (EM) “Alternative
Project,” focuses on providing scientific and policy support for MNA/EPR. The initial product of the technical working group
was a summary report that articulated the conceptual approach and central scientific tenants of
the project, and that identified a prioritized listing of technical targets for field research. This
report documented the process in which: 1) scientific ground rules were developed, 2) lines of
inquiry were identified and then critically evaluated, 3) promising applied reseach topics were
highlighted in the various lines of inquiry, and 4) these were discussed and prioritized. The
summary report serves as a resource to guide management and decisionmaking throughout
the period of the subject MNA/EPR Alternative Project. The series of supplemental
documents present the full texts from the technical analyses within the various lines of
inquiry (see listing below).
Report ID:
Summary Report: Natural and Passive Remediation of Chlorinated Solvents: Critical Evaluation of Science and Technology Targets, WSRC-TR-2003-00328 This is the baseline document that describes the conceptual approach
and central scientific tenants in which the project would invest its resources.

Attenuation: Lines of Inquiry Supporting Monitored Natural Attenuation and Enhanced Passive Remediation of Chlorinated Solvents, WSRC-TR-2003-00332 Supporting document to WSRC-TR-2003-00328 that documents the project team’s evaluation of the state of the science of the characterization and monitoring process and tools.
Historical and Retrospective Survey of Monitored Natural Attenuation: A Line of Inquiry Supporting Monitored Natural Attenuation and Enhanced Passive Remediation of Chlorinated Solvents, WSRC-TR-2003-00333 Supporting document to WSRC-TR-2003-00328 that documents the results of a survey of site owners with chlorinated solvent plumes to assess, using a retrospective survey, what
has worked and where there are barriers to implementation. |
