Five years after the Deepwater Horizon oil spill in the Gulf of Mexico, residents and ecologists say the effects of the disaster are still being felt.

An explosion on the Deepwater Horizon drilling rig on April 20, 2010, resulted in the largest accidental release of oil into marine waters in history. Estimates of the size of the spill vary, but a U.S. government panel puts it at 650 million litres between the time of the explosion and when the well was finally capped 87 days later.

The CBC's Paul Hunter visited Louisiana to find out how the spill continues to affect the region.​
