Contaminated Sediment Remediation Guidance Released
On December 28, 2005, EPA's Office of Solid Waste and Emergency Response issued the final Contaminated Sediment Remediation Guidance for Hazardous Waste Sites. Contaminated sediment can significantly impair the navigational and recreational uses of many rivers and harbors in the United States, and is a contributing factor to the need for fish consumption advisories.
The guidance encourages project managers to consider a number of factors during cleanup of contaminated sediment, such as:
- Identifying and controlling the sources of sediment contamination and identifying the pathways of contaminant exposure, prior to cleanup;
- Using a technical team approach, and involving the community and other stakeholders throughout the cleanup process;
- Considering all three major approaches to management of contaminated sediment (monitored natural recovery, in-situ capping, and dredging), and considering alternatives which combine approaches;
- Validating models used to support sediment decisions and considering model uncertainty and sensitivity;
- Considering how contaminated sediment alternatives manage or reduce risks, including consideration of residual risks; and
- Monitoring the effectiveness of remedies at contaminated sediment sites.
The final guidance is available on EPA's Contaminated Sediments in Superfund Web site. For additional information, contact Leah Evison (email@example.com) of the Office of Superfund Remediation and Technology Innovation.
