News release: “U.S. Environmental Protection Agency Regional Administrator Judith A. Enck was joined by New York State Department of Environmental Conservation Deputy Commissioner Eugene Leff today to kick off the start of the fourth season of dredging in the Upper Hudson River. Portions of the Upper Hudson are being dredged to remove sediment contaminated with polychlorinated biphenyls (PCBs), which are potentially cancer-causing chemicals that build up in the food chain and can cause neurological damage, especially in children. In 2013, dredging will begin south of the village of Fort Edward, New York around Griffin Island and will continue south in the main stem of the river to the Thompson Island Dam. Additional dredging is planned between Champlain Canal Lock 5 and 6 near the towns of Northumberland and Schuylerville…The historic dredging project targets approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile stretch of the upper Hudson River between Fort Edward and Troy, New York. At the end of the 2012 dredging season, the project was nearly half-way to its target with more than 1.3 million cubic yards removed since the project began in 2009. The dredging goal for 2013 is 350,000 cubic yards. The rest of the cleanup is expected to take three to five more years to complete.”
