Abstract:

This document provides a technical guide for project managers and management teams evaluating and implementing monitored natural recovery MNR at contaminated sediment sites. It is primarily intended to support environmental restoration at United States Department of Defense DoD sites however, many aspects of the document also may be useful for other government organizations, potentially responsible parties, communities, and stakeholders involved in management of sediment cleanup. Specific objectives include 1. Establishing principles and evaluation criteria for the comprehensive and cost-effective evaluation of MNR as a remedial option. 2. Providing a framework to properly design, implement, and monitor MNR and to predict the long-term performance of natural recovery processes in managing or reducing ecological and human health risks. In meeting these objectives, this technical guide promotes consistency among practitioners in developing lines of evidence to evaluate the site-specific suitability of MNR and in applying MNR to sediment sites. It provides a framework to consider alternative remedies or, as appropriate, to enhance MNR via thin-layer capping or other actions that might be required to achieve appropriate risk reduction within an acceptable time frame.
