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 4 dredging began on May 7, 2014 and ended in November 2014.  Backfilling continued into December 2014. Approximately 582,000 cubic yards of PCB-contaminated sediment was removed during the 2014 dredging season. Since the dredging project began in 2009, more than 2.5  million cubic yards of PCB-contaminated sediment have been removed from the Hudson River. Phase 2 dredging operations will resume in spring 2015.

Phase 2 data is collected daily during the dredging season. To view Phase 2 data, click on one of the categories on the left side of the screen (monitoring pages), 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 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.
