4 Based on the latest available data, just one year after dredging was completed, EPA noted improvements in PCB levels in fish. The Agency’s 2017 Five Year Review Report notes: “2016 fish data suggest that fish have begun to recover from dredging impacts and are generally declining … it is anticipated that it will require approximately 8 years for fish tissue to decline to 50 percent of its current PCB concentration …”4 No additional dredging in the Upper or Lower Hudson was recommended. Water, sediment and fish data will be collected for the foreseeable future, and EPA will continue to monitor river conditions closely. EPA CHOOSES BALANCED APPROACH EPA selected dredging as the remedy for PCBs in sediments in the Upper Hudson in 2002 after 12 years of study and input from scientists, environmental groups, elected officials and local community representatives. The Agency considered multiple options ranging from no dredging to an even larger dredging project than was ultimately selected. The chosen remedy was grounded in a careful, quantitative analysis and tailored to the specific conditions of the site.
