The oil spill resulting from a pipeline explosion in the port city of Dalian on July 29th is being cleaned up by a small army of fisherman, locals, and government workers manning over 250 oil-skimming vessels and 8,000 fishing boats - much of the work being done by hand. The spill, now contained according to authorities, grew to 430 square kilometers (165 sq mi), but was prevented from fouling international waters. The explosion was due to improper desulfurizer injections into the pipeline, according to a report by Xinhua, China's state news agency. As workers continue their efforts and watchdog groups like Greenpeace level criticism for what they call an inadequate response to date, Dalian Port has already resumed operations at two of its oil berths, the company said on Sunday.
