Dredging The Hudson River For PCBs Tens of thousands of years ago‚ glaciers carved out the Hudson River. It is an estuary‚ " An estuary is a semi-enclosed coastal body of water with a free connection to the open sea and within which sea water is diluted by fresh water"(life.bio.sunysb.edu). The Hudson River begins in Lake Tear of the Clouds on the southwest side of Mount Marcy‚ the highest peak in New York‚ and is 315 miles long. At its deepest point‚ World ’s End near West Point‚ it is 216 feet

Over a span of nearly thirty years‚ more than a million pounds of polychlorinated biphenyls (PCBs) were released into the Hudson River‚ severely polluting the water and harming the wildlife that inhabit it. These toxins‚ which are responsible for the death of many fish and birds and the cause of many serious health problems in humans‚ settle to the bottom of the river‚ as they are unable to break down. One species in particular that was affected by this extreme level of pollution was the Hudson River

learned about PCBs in CCP and broke paper destined for recycle. NCR did not keep their use of Aroclor 1242 a secret: for example‚ this fact was published in the form of patents. Recycling paper mills were aware that CCP and broke paper needed de-inking before they could be re-sold as recycled paper. What is important is not whether NCR or the mills knew PCBs were being released to the River through that process but rather implications of the releases. At the time there were no PCB discharge regulations

biphenyls (PCBs)‚ which have been widely used as plasticizers‚ hydraulic and heat exchange fluids‚ coolants and lubricants in transformers and capacitors‚ may also be present in the e-waste stream. Due to its high capacity to store pollutants‚ soil appears to be the major sink for PCBs in various environments (Dalla Valle et al.‚ 2005). Soil samples collected from several villages in Taizhou e-waste recycling area contained high levels of PCBs (52.0 - 5789.5 μg/kg) (Tang et al.‚ 2010a). PCBs were also
