Erin Brockovich is an environmental activist known for a significant legal case against Pacific Gas and Electric Company (PG&E). She helped bring a lawsuit on behalf of residents of Hinkley, California whose drinking water was contaminated with hexavalent chromium from PG&E's operations. The contamination caused numerous health issues in the community. The case resulted in a $333 million settlement, the largest direct-action lawsuit settlement in U.S. history at that time. Brockovich continues to advocate for communities affected by pollution and educate about the dangers of hexavalent chromium.
