ITRC Publishes New Guidance Document on Contaminated Sediments Remediation
Remediation of contaminated sediments commonly targets the complimentary goals of protecting human health and the environment and restoring impaired environmental resources to beneficial use. Remediating contaminated sediment sites is challenging from a technical and risk-management perspective. A new ITRC web-based guidance document presents a remedy selection framework for contaminated sediments to help project managers evaluate remediation technologies and develop remediation alternatives based on site-specific data. General categories of contaminated sediment remedial technologies covered in the guidance document include monitored natural recovery (MNR) and enhanced monitored natural recovery (EMNR), in situ treatment, capping (conventional and amended), and removal (dredging and excavation). Additional factors that need to be considered as part of the evaluation process are summarized (e.g. feasibility, cost, stakeholder and local governments concerns, and others).
