Remediation of Contaminated Sediments Training Course
Training > Sediments > Remediation of Contaminated Sediments
Remediation of contaminated sediments commonly targets the complimentary goals of protecting human health and the environment and restoring impaired environmental resources to beneficial use. Although the selection and implementation of sediment remedies can be straightforward for simple sites, many contaminated sediment sites are challenging from a technical and risk-management perspective. This training course offers a remedy selection framework to help project managers evaluate remedial technologies and develop remedial alternatives (often composed of multiple technologies) based on site-specific data. General categories of contaminated sediment remedial technologies covered in this training course include monitored natural recovery (MNR) and enhanced monitored natural recovery (EMNR); in situ treatment; capping (conventional and amended); and removal (dredging and excavation).
Remedy Selection for Contaminated Sediments
The sediments underlying many of our nation’s major waterways are contaminated with toxic pollutants from past industrial activities. Cleaning up contaminated sediments is expensive and technically-challenging. Sediment sites are unique, complex, and require a multidisciplinary approach and often project managers lack sediments experience. ITRC developed the technical and regulatory guidance, Remedy Selection for Contaminated Sediments (CS-2, 2014), to assist decision-makers in identifying which contaminated sediment management technology is most favorable based on an evaluation of site specific physical, sediment, contaminant, and land and waterway use characteristics. The document provides a remedial selection framework to help identify favorable technologies, and identifies additional factors (feasibility, cost, stakeholder concerns, and others) that need to be considered as part of the remedy selection process. This ITRC training course supports participants with applying the technical and regulatory guidance as a tool to overcome the remedial challenges posed by contaminated sediment sites. Participants learn how to:
- Identify site-specific characteristics and data needed for site decision making
- Evaluate potential technologies based on site information
- Select the most favorable contaminant management technology for their site
For reference during the training class, participants should have a copy of Figure 2-1, Framework for Sediment Remedy Evaluation. It is available as a 1-page PDF at http://www.cluin.org/conf/itrc/ContSedRem/ITRC-SedimentRemedyEvaluation.pdf.
Participants should also be familiar with the ITRC technology and regulatory guidance for Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites Website (CS-1, 2011) and associated Internet-based training that assists state regulators and practitioners with understanding and incorporating fundamental concepts of bioavailability in contaminated sediment management practices.
