Erin Brockovich, an environmental activist who was central to winning a lawsuit against a major utility over groundwater contamination, on Tuesday spoke at Indiana University Southeast.

Brockovich became famous when her actions in the case against Pacific Gas & Electric were told in the 2000 movie "Erin Brockovich," which starred Julia Roberts.

Her speech at IUS' Sanders Speakers Series gave insight into her childhood struggles with dyslexia, time during the lawsuit and what she has been working on to make sure people across the nation have clean water.

"There's three pivotal people in my life that were preparing me for what was going to come," Brockovich said. "But I didn't know what was coming."
