In 1970s Woburn, Massachusetts, families noticed too many children with leukemia on too few streets, and two municipal wells were found laced with industrial solvents. Mothers organized, and the trial later told in A Civil Action showed how hard it is to prove causation in court. That lesson fed Congress toward the 1980 Superfund law, built on strict, retroactive liability.
Whether the well water caused the leukemias is formally open: the cluster is established but the causal link is probable, not proven. Fairness of the Beatrice verdict and the accuracy of A Civil Action are also argued, as are Superfund's costs and benefits.
