how did they clean up exxon valdez oil spill?

Answer 1

A trial burn was conducted during the early stages of the spill, in a region of the spill isolated from the rest by a fire-resistant boom. The test was relatively successful, but because of unfavorable weather no additional burning was attempted in this cleanup effort. Mechanical cleanup was started shortly afterward using booms and skimmers, but the skimmers were not readily available during the first 24 hours following the spill, and thick oil and kelp tended to clog the equipment. A private company applied dispersants on March 24 with a helicopter and dispersant bucket. Because there was not enough wave action to mix the dispersant with the oil in the water, their use was discontinued.
