"It's disgusting that oil companies dump wastewater into California's ocean," said Miyoko Sakashita, CBD oceans director, in a press release. "You can see the rigs from shore, but the contaminated waters are hidden from view. Our goal is to make sure toxic fracking chemicals don't poison wildlife or end up in the food chain."

Fracking wastewater contains more than just the chemicals used by oil and gas companies to break up the rocks, including toxic substances like methanol, benzene, naphthalene, and trimethylbenzene. It can also include nasties that it picks up from those deep rock formations, including lead and arsenic. And while safely disposing of such substances isn't easy in the best of situations, ocean disposal poses special risks for those who play in, live near, or eat fish from the sea.
