Erin Brockovich explains how she uncovered PG&E's use of hexavalent chromium — a cancer-causing chemical — in Hinkley, California, leading to a $333 million settlement for 634 plaintiffs. She describes how PG&E held town halls telling residents the chromium in their water was safe and found in breakfast cereal, deliberately omitting that it was the toxic hexavalent form. Now she's raising the same alarm about AI data centers being built in secrecy — including Meta's 4-million-square-foot 'Hyperion' campus in Louisiana — warning that the pattern of hidden environmental harm is repeating itself.
Key Moments
Erin Brockovich
“You piss off one mom and you pissed off Roberta and they've got great instincts and they think you're lying to them, they're going to go find 10 other fuckin' pissed-off moms and they're going to actually use these instincts and they will come at you.”
Erin explaining how PG&E's deception at town hall meetings backfired by uniting community mothers against the company.
“It never dawned on me that I had to be any of that.”
Erin responding to being told she wasn't a doctor, lawyer, scientist, or politician — and therefore had no standing to investigate the Hinkley contamination.
“They were telling everybody that it was chromium in their water, which is a natural element, and it's good for you. You can find it in your breakfast cereal. They weren't telling him that it was hexavalent chromium, and it was a poison.”
Erin describing how PG&E misled Hinkley residents at town hall meetings about the chemical contaminating their water supply.
Erin Brockovich is an environmental activist and consumer advocate best known for building the landmark case against Pacific Gas and Electric Company, which resulted in a $333 million settlement — the largest ever paid in a U.S. direct-action lawsuit at the time. Her story was immortalized in the 2000 film 'Erin Brockovich,' starring Julia Roberts. She continues to advocate for communities affected by pollution and corporate negligence, and has more recently turned her attention to the environmental and resource impacts of AI data centers.
Takeaways
1
Secrecy is the first red flag for environmental harm Brockovich's core heuristic — developed across Hinkley, Flint, and BP — is that harmful projects are built in secret. She applied this directly to Meta's 4-million-square-foot 'Hyperion' AI campus in Louisiana, asking: if data centers are so beneficial, why aren't communities being openly consulted about their water and energy consumption?
2
Filing as direct action, not class action, maximized victim compensation The 634 Hinkley plaintiffs were represented in a direct action suit rather than a class action, allowing damages to be individually calibrated — those closest to the PG&E facility with decades of high-level exposure received far more than those on the plume boundary. This legal structure was critical to the $333 million outcome.
3
Corporate deception, not pollution, is the real crime PG&E didn't just contaminate Hinkley's water with hexavalent chromium — they actively told residents at town halls it was safe, naturally occurring chromium found in breakfast cereal. Brockovich argues communities can handle the truth and adapt, but the deliberate lie denies them the chance to protect themselves.
4
Angry, organized mothers are the most effective environmental force In every major case Brockovich has worked — Hinkley, Flint, BP oil spill — a single mother's suppressed concern became a formidable coalition once other mothers joined. She argues that institutional dismissal ('hysterical mother') backfires, because it motivates these women to return armed with facts and allies.
5
Dyslexic pattern recognition drove the Hinkley investigation Brockovich credits her dyslexia — specifically her instinct to calculate backwards from high historical numbers rather than forward from current readings — with helping her build the contamination timeline that proved long-term exposure. She is now an ambassador for Made by Dyslexia alongside Richard Branson, and notes there are an estimated 1 billion dyslexics globally.
