An Introduction to the ISRAP and Long-Term Monitoring Strategies for Contaminated Sediment Management Guidance

The goal of this web portal is to illustrate an optimized, cost-effective framework to bridge the gap between detailed monitoring tool descriptions and general guidelines that identify monitoring needs. The Navy (under the Navy's Environmental Sustainability Development to Integration (NESDI) program) developed this contaminated sediment monitoring guidance for sediment sites that undergo remediation.

This guidance also serves as a detailed reference companion for the remedy-specific validation and monitoring matrices of the Interactive Sediment Remedy Assessment Portal (ISRAP). The ISRAP relates monitoring tools to specific monitoring needs for dredging, capping, and monitored natural recovery (MNR), to help remedial project managers (RPMs) focus on key issues associated with site-specific monitoring needs and tools and to facilitate the design of cost effective and meaningful monitoring plans. The interactive tool facilitates navigation of the large volume of information in the matrices, and allows technical contents to be updated and modified over time.

It is envisioned that this guidance will be useful to RPMs at a variety of stages in the Remedial Investigation/Feasibility Study (RI/FS) process, but will be particularly useful in understanding and planning for monitoring needs following remedy implementation at contaminated sediment sites.  The ISRAP can also be useful in understanding data needs during RI/FS, especially as they pertain to remedies themselves, and post-remedy monitoring. 

Information presented in the ISRAP is meant to be comprehensive, and should only be used as an approximate guide. The monitoring tools and needs listed in the ISRAP address a wide spectrum of stakeholder concerns and remedial goals that are not all likely to be relevant for all sites. Alternately, due to the evolving nature of science and engineering aspects of sediment management and wide array of stakeholder concerns, the ISRAP does not include all remedy functions or critical monitoring questions. Users should default to stakeholder and regulatory concerns - remedial needs should be identified from site-specific remedial action objectives (RAOs) or the record of decision (ROD) prior to using the matrices to investigate the details associated with remedial needs and assist in the identification of appropriate monitoring tools.


The ISRAP was created by Space and Naval Warfare Systems Center Pacific (SSC Pacific) under the Navy's Environmental Sustainability Development to Integration (NESDI) program, with technical assistance from ENVIRON International Corporation.
