There's no end in sight yet as thousands of gallons of oil spew uncontrolled into the Gulf of Mexico each day.
Reports estimated that at least 20 million gallons are now believed to have leaked into the ocean since BP-leased Deepwater Horizon oil rig exploded on April 20 and sank. Eleven workers were killed in that incident.
After many efforts to stop a gushing oil well in the Gulf have failed, BP plans a new approach while the White House sends more resources.
The British oil giant has acknowledged failure in its "top kill" attempt to plug the underwater well. Company officials said it could take a week to implement the next bid -- placing a cap over the leak.
The disaster has already closed stretches of coastal fishing waters, endangering the seafood industry and tourism, and threatening a catastrophe for Louisiana marshes, home to many rare species, according to news reports.
