PCB Remedial Dredging: Phase 1 Results and Relevance to New York/New Jersey Harbor Estuary
Monday, March 15,
Smithsonian's National Museum of the American Indian, New York, New York
The Hudson River Foundation hosted a seminar on Monday, March 15, 2010, concerning Phase 1 of remedial dredging of the Hudson River PCBs SuperFund Site. Mr. Walter Mugdan, Director of the Emergency and Remedial Response Division at the Region 2 office of the U.S Environmental Protection Agency (EPA) presented a summary of the Phase 1 dredging operation, completed by the General Electric Company in October 2009, and EPA’s findings to date.
The upriver PCB issue is critically linked to past, present, and future conditions of the New York/New Jersey Harbor Estuary. For example, the Contamination Assessment and Reduction Project (CARP) found that the Upper Hudson River PCBs Superfund Site is the dominant external source of PCBs to the Harbor Estuary. Additionally, through modeling, CARP concluded that if PCB loadings continue at current levels, sediments in most of the Harbor Estuary are likely to remain “contaminated” (by dredged material ocean disposal standards) even three decades from now. The seminar provided important information about progress and decisions being made now that will impact future conditions in the Harbor Estuary.
