It’s been over a week since a ruptured underwater pipeline led to an oil spill across Southern California’s coastline, taking a big toll on the environment, wildlife, and local economy.

As the mitigation and recovery efforts continue, investigators are still grappling with questions around the cause of the incident and how it could have been prevented.

Residents and business owners have filed lawsuits against the pipeline operators, and in the meantime, safety regulations are being brought under the spotlight.
