Materials balance on an oil washed from a sandy substrate using shoreline cleaners | Conference Paper individual record

An experiment was conducted at a wave-tank facility, investigating shoreline-cleaner use on oiled sandy substrates. In each tank, a beach was configured, wave/tidal cycles were used, and alongshore currents were simulated through the use of influent/effiuent flow ports. The experimental treatments included oiled control, oil-plus-Corexit® 9580, and oil-plus-CytoSol®. Oil was applied to each beach and weathered 24 hr before experimental onset. Some comparisons between treatments were difficult. In the oiled-control tank, 75% of the oil could not be accounted for in the materials balance; this was partially due to beach erosion. The CytoSol tank also experienced beach erosion to a similar degree, but most of the oil was accounted for in the materials balance. The CytoSol shoreline cleaner was more effective than the Corexit 9580 cleaner. CytoSol mobilized and removed a higher percentage of the oil from the sandy substrate, with the aid of the high-energy waves. The CytoSol-treated slick was more manageable and easier to collect at the end of the experiment. The CytoSol-treated oil was subject to entrainment in the water column, as evidenced by the higher oil losses in the effluent. This is an abstract of a paper presented at the 23rd Arctic and Marine Oil Spill Program, AMOP Technical Seminar (Vancouver, British Columbia, Canada 6/14-16/2000).
