The largest environmental dredging project ever undertaken in the United States occurred in the ______.

The largest environmental dredging project ever undertaken in the United States occurred in the ______.

• A. Lower Hudson River
• B. Great Lakes
• C. Mississippi River
• D. Upper Hudson River

Answer: (D)

The event tests understanding of large-scale environmental remediation, specifically PCB cleanup in the Hudson River. The cleanup of PCB-contaminated sediments in the Upper Hudson River, part of the General Electric Superfund site, is widely cited as the largest dredging project in U.S. history. Over roughly 40 miles of river, about 2.6 million cubic yards of contaminated sediment were dredged and treated for disposal, a scope that surpasses other U.S. dredging efforts. The other locations listed have dredging or remediation, but not on this same scale for environmental cleanup of PCBs, which is why the Upper Hudson River is the correct context.
