This site provides access to performance standard monitoring data that is being generated as part of Phase 2 dredging and sediment processing facility operations. For more information about the Hudson River PCBs Superfund Site go to: www.epa.gov/hudson.

Phase 2 Year 3 dredging began on April 29, 2013 and ended in November 2013.  Backfilling continued into December 2013. Approximately 628,000 cubic yards of PCB-contaminated sediment was removed during the 2013 dredging season. Since the dredging project began in 2009, more than 1.9 million cubic yards of PCB-contaminated sediment have been removed from the Hudson River.  Phase 2 dredging operations will resume in spring 2014. 

To view Phase 2 data, click on one of the categories on the left side of the screen, or go to the interactive data maps. The interactive data maps show, by location, project activities and monitoring data for both engineering performance standards of water quality (resuspension) and quality of life performance standards such as air quality, odor, noise, lighting, and navigation.

Phase 1 dredging occurred between May 15 and October 26, 2009. Performance standard monitoring data was collected daily between May and December 2009. Phase 1 data can be accessed at the bottom of each monitoring page. The second phase of the Hudson River dredging project began in spring 2011. Dredging occurred between June 6 and November 8, 2011, May 9 and mid-November 2012, and April 29 and November 2013.
