The effort to place a containment dome over one of two remaining leaks from last month’s Deepwater Horizon oil spill has failed.

According to CNN, BP was unable to place the structure over the breach due to large volumes of hydrates – crystals which form when gas combines with water – accumulated inside the dome.

The structure is now sitting on the ocean floor off to the side of the wellhead.

Surfrider Foundation has also received unconfirmed reports that the effort may have somehow actually made the situation worse.
