Restored wetland at New Bedford Harbor Superfund Site
|
Cleanups selected at 150 sites - As of September 2005, Superfund has selected a remedy at over 150 sediment sites. Eleven of these sediment sites are considered "mega sites" where the cost for the sediment portion of the remedy exceeded $50 million. There are approximately 50 other sites with ongoing sediment investigations, several of which are expected to become mega sites.
Key Principle in Remedy Evaluation - EPA encourages it project managers to develop and refine a conceptual site model that considers key site uncertainties and use it within an adaptive management framework to select and implement a cost-effective remedy that controls sources and achieves long-term protection while minimizing short-term impacts.
