exxon valdez spill (alaska)

Ship spilled 10.8 us gallons. Beach applications of dispersants were tried in several locations. Corexit 7664 was applied on Ingot Island, followed by a warm water wash. No significant change in oil cover or the physical state of the oil was observed as a result of the treatment. Some ecological impacts were observed in the treated areas. It appeared that the effects were largely due to the intensive washing more than to the use of Corexit 7664, and were evident in intertidal epibenthic macrobiota.
