I want to know the answer to the following question:
How many tons of PCBs were claimed to have been dumped by GE's Waterford Plant in the 1983 lawsuit?
All the background I'm provided with is that "In 1999, the company agreed to pay a $250 million settlement in connection with claims it polluted the Housatonic River (Pittsfield, Massachusetts) and other sites with polychlorinated biphenyls (PCBs) and other hazardous substances.". Is that enough to answer the question?
