No can do. Regulations prohibit dumping the separated water back into the Gulf.
Oil is vacuumed up with seawater and separated on the ships with the clean water discharged back to the sea. If it has a sheen the fines are huge to the captain of the vessel. Guess it is better to have all that oil in the gulf than have a slight sheen on the excess water that would soon biodegrade,
Wow, much work needs doing cleaning up uber stupid reg. and procedures created by very smart stupid people!
