While surface oiling from the roughly 11-million-gallon spill of crude has disappeared, oil now turns up with some regularity just under the surface of tidal sediments in areas that initially had been heavily hit. Or so notes a 2009 Status Report that was issued this month by the Exxon Valdez Oil Spill Trustee Council. This joint state-and-federal body was established to oversee the use of a $900 million civil settlement (collected from Exxon Co. USA, now ExxonMobil) to restore the area’s oil-hammered ecosystems.
The natural removal of this residual oil has slowed to a glacial pace, it says — “0 to 4 percent per year, with only a 5 percent chance that the rate is as high as 4 percent.”
Especially troubling, it adds: In some places this oil “is nearly as toxic as it was the first few weeks after the spill.”
