Pacific Gas & Electric (PG&E) was in trouble. Serious trouble. Four decades after the world's largest utility started dumping 370 million gallons of cancer-causing chemicals into unlined ponds in Hinkley, California, the company's actions had finally been uncovered. Uncovered by Erin Brockovich (a formerly unemployed, single mother of three working in a California law firm) who wanted to know what medical records had to do with a real estate file. What she found out led to the biggest settlement on record for a civil class action lawsuit.
