What was done to clean up the PCB pollution in the Hudson River?
In 2001, after a ten-year study of PCB contamination in the Hudson River, EPA proposed a plan to clean up the river by dredging more than 100,000 pounds (45,000 kg) of PCBs. The worst PCB hotspots are targeted for remediation by removing and disposing of more than 2.6 million cubic yards of contaminated sediment.
Is the Hudson River being cleaned?
The Hudson River is not cleaning itself. But the decline is largely due to the ban on PCB discharges that went into effect that year. When direct discharges of the contaminant were stopped, PCB concentrations in river water and fish, logically, dropped as well.
Is the Hudson River still a Superfund site?
Today, 200 miles of the Hudson River is classified by EPA as a Superfund site – one of the largest in the country. In 1984, 200 miles of river, between Hudson Falls and the Battery in New York City, was placed on EPA’s National Priorities List of the country’s most contaminated hazardous waste sites.
Did the dredging project work?
Yes. Data show the Hudson River dredging project is working. PCB levels in water have dropped at every monitoring station along the Hudson, ranging from a 78% reduction near Fort Edward to a 54% reduction near Poughkeepsie.
What is the dirtiest river in the world?
Citarum River
1. Citarum River, Indonesia – The Citarum River is known as the most polluted river in the world and is located in West Java, Indonesia.
Is the Hudson River polluted?
It’s honestly just common sense to not take a dip in the Hudson River. It’s polluted with PCBs (polychlorinated biphenyls — which are man-made chemicals), cadmium, sewage, urban runoff, heavy metals, pesticides, and lots and lots of bacteria. Also, dead bodies have been found in the river (this is a recent example).
How much would it cost to clean the Hudson River?
It is estimated that those under construction will cost $967‐million and those being designed, $412‐million. Of the $1.4‐billion cleanup cost, the Federal Government Is paying $878‐million, New York State $353‐million and localities $213‐million.

Where was the Hudson River PCBs Superfund site?
In February 2002, the EPA issued a Record of Decision (ROD) for the Hudson River PCBs Superfund Site that called for targeted environmental dredging of approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile section of the Upper Hudson River from Fort Edward to Troy, NY.
Who is involved in the Hudson River cleanup?
(See Investigating the Floodplain for more information.) EPA is the lead agency for cleanup of the Hudson River PCBs Superfund site. The New York State Department of Environmental Conservation (NYSDEC) is the support agency for this project.
When did GE start cleaning up the Hudson River?
On May 15, 2009, GE began the long-delayed clean-up of the Hudson River! Although the project is slated to operate 24 hours per day, due to changes in the river flow, the actual number of hours of dredging was far lower.
How long will it take to remove PCBs from the Hudson River?
Phase 1 dredging was scheduled to run for approximately 6 months in the upper Hudson and remove approximately 10% of the PCBs slated to be removed. Phase 2 will remove most of remaining targeted contaminants and operate for several years.
