Natural and Passive Remediation of Chlorinated Solvents: Critical Evaluation of Science and Technology Targets

This report was written for multiple audiences. Each reader will likely approach the subject from a different perspective, seeking different information. The team that developed the document consisted of several technical experts on monitored natural attenuation (MNA) and included participants who were integral in the development of US EPA's chlorinated solvent MNA protocol and the subsequent US EPA and Office of Solid Waste and emergency Response (OSWER) policy directive. The primary assignment to the interdisciplinary team was to generate a summary of the state-of-the-art, particularly for chlorinated solvent applications and to identify high-priority opportunities for advancement. A diverse jury of peers reviewed the draft report; the report was edited in response to their comments.
