Cleanup of the Superfund site of the Hudson River started with a scoop of mud being extracted by dredge guided by a computer. PCBs are going to be removed round the clock six days a week from May to October. The sediments are then transported by freight trains to a hazardous landfill in Texas. The cause of the Superfund Site is from two General Electric factories that contaminated the land for three decades before PCBs are banned. Dredging of the 197 mile land is suppose to be continued until 2015.
If there are no delays, the cleanup of the Hudson River will probably be completed by 2015. It is important to cleanup hazardous materials from the environment and I am glad to hear this cleanup is finally starting. The Hudson River is a defining and important landmark of New York, so I hope the plan succeeds.

This fits in nicely with our class discussions on PCBs and clean-up!
