Hudson River Dredging - Essay Example

GE, along with supporters from a portion of the public, strongly opposed dredging as a cleanup option, stating that it was unnecessary since the river was eliminating the PCBs through natural means. However, in 2002 EPA initiated the dredging of two million cubic meters of sediment to remove an estimated 68,000 kilograms of PCBs from a 250-kilometer stretch of the upper Hudson. For the design and implementation of the dredging project, active public involvement was ensured by EPA2. The fish caught from the upper Hudson River were found to be contaminated with the 209 different chemical compounds of PCBs which accumulate in its fat tissues.

Humans who consume contaminated fish increase their risk of cancer. Currently, PCB pollution is such that fishing for the purpose of human consumption is prohibited in the upper Hudson River, and permitted only to a limited extent downstream, by health advisories3. While cleaning the Hudson River through dredging and remediation are essential, the technological feasibility, the overall environmental benefits, the adverse impacts caused by hazardous waste from the operations, and the problems caused to nearby communities need to be taken into consideration.

Thesis statement: The purpose of this paper is to discuss Hudson River dredging and remediation to remove PCBs; and to examine the environmental benefits and disadvantages resulting from the operations. The Hudson River in New York State is one of the best known examples of a large river system with widespread sediment contamination with PCBs. The upper forty miles of river will undergo cleaning operations, with 2.65 million cubic yards of sediment proposed to be removed. Cleanup has yet to begin, although dredging of 265,000 cubic yards from 94 acres is planned for the first year of dredging operations4.
