The government thought that new sediments will accumulate & bury the contamination, the Environmental Protection Agency thinks this is ideal because:
put more effort into safe handling and
transporting the PCBs.
The role of all environmental groups was to stop the contamination in the body's of water. They started to really show interest after the spill in the Hudson River. These groups were:

PCB's contaminated the Fort Edward Dam which was south from the Fort Edward plant where General Electric's employs were working on compacitors.
A puddle of PCBs in the Fort Edward Dam emptied into the Hudson River. After that event government started testing and searching for a solution. Eventually between Fort Edward and Troy in N.Y. there were 40 hot spots.
Located south of the Fort Edward plant. The Thompson Island Pool has the most concentrated pollution of PCBs. This was all caused by the removal of the Fort Edward Dam which led to the downstream movement of PCBs.
-Chloracne: Combination of
blackheads and pustules.
Similar to adolescent acne.
If exposed to PCB's for a short term and with low levels, PCB's did not cause any serious injury's.
Long term exposure can let PCB's enter the body through:
It's been linked to liver damage by "The Journal of Industrial Hygiene and Toxicology".
PCBs associated to breast cancer but it has not been proven yet.
-Breast tissue from nine women that were alive in 1994 & 1997 were tested.
Their hasn't been any significant evidence yet but it's still being tested. .
In 1977 & 1980 used for hydraulic fluids like:
-Surface coating for carbonless copy paper
-Plansticizers in sealants
-Caulkings -Synthetic resins
-Rubbers -Paints
-Waxes - Asphalts
-A flame retardants in lubricating oils.
An Industrial chemical used by electrical Industry's.
Used for a safer cooling and insulating fluid for industrial transformations and capacitors.
-Monsanto Corporation produced PCB's and licensed others
to do the same.
-1200 people were poisoned in Japan by rice oil containing
PCB's
PCB's caused health problems since their beginning. Monsanto Corporations were aware but continued using the product because of great results. In a meeting with the U.S Public Health Service Monsanto Corporations said that they would stop because it was a "miracle chemical that could not be replaced"
