Another alternative may exist besides the options of incineration. There is the process called bioremediation. The PCB's in the ground can be eliminated by the action of bacteria. Specific bacteria are cultivated and manufactured that can break down PCB and other Chlorinated hydrocarbons. A soil farming method possibly could be used on site to reduce the PCB levels to reasonable amounts. It may also cost a lot less that having to truck soil out or having to have a incinerator located on site. I was just wondering why this solution has not been thought about and if so why was it not thought to be a viable method for reducing PCB levels in the contaminated soil and ground water.
