- One sample is already being tested
- Tar balls and an oil mat have been found since Hurricane Isaac
- BP says it's investigating whether oil is from the 2010 Gulf spill
- It's possible the oil is from another source, a BP spokesman says
BP said Wednesday it is heading to the Louisiana coast to test whether tar balls and oil found on shore after Hurricane Isaac are from the company's 2010 Gulf oil spill.
State officials reported tar balls and a large oil mat along the Gulf shore south of New Orleans, and the U.S. Coast Guard reported finding three oiled birds in the area on Monday.
BP spokesman Ray Melick said the area is one where BP teams were already helping with cleanup from the 2010 spill before Isaac arrived. As soon as they're given the all-clear, they will return to do more cleanup and test whether the new oil is from their spill or another source.
"There's a lot of oil out there that may not be ours," Melick said.
