Wow, we studied this case almost to ad nauseam when I was pursing a BS in Environmental Science between 1976-80.
General Electric was accused of dumping large amounts of toxic and carcinogenic chemicals into the food chain. It was alleged that one of the conglomerate's subsidiary businesses dumped an estimated 1.3 million pounds of PCB's (polychlorinated biphenyls) into the Hudson River between 1947-77, consequentially ruining fisheries, countless lives many lives? When it became obvious that indeed, GE was responsible for poisoning the river and they were asked to clean it up, they dug in their heels, hid behind counsel, and waited until their accusers gave up. But they never did.
Now, after more than sixty years after they began dumping hazardous waste from a transformer plant in Hudson Falls into the Hudson River, a court in Washington ruled that they must clean it up.
GE loses to EPA in ruling on river dredging
