This research test program was initiated by the U.S. Environmental Protection Agency (EPA) to determine the effect sorbent materials and fire fighting foam have on containment, recovery and vapor suppression of floatable hazardous materials (HM) spilled on water. The test plan incorporates some of the equipment used during a 1975 U.S. EPA hazardous materials test at the Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT). The devices used in both programs were the Clean Water Incorporated Harbour Boom and the Industrial and Municipal Engineering Swiss OELA III Skimmer. Dioctyl phthalate (DOP), octanol, and naphtha served as the hazardous materials. The sorbent materials were polyurethane foam cubes, Clean Water, Inc. Sorbent C and Dow Chemical Co. Imbiber Beads. An aqueous film forming foam (AFFF), FC-206, from 3M Company was used as the fire fighting foam. The type of HM, Sorbent, tow speed, and wave condition served as controlled and independent variables. Critical tow speed of the boom (the speed at which oil loss began), HM vapor concentration, and fluid recovered by the skimmer were the dependent variables. Results of the tests were evaluated in terms of the differences in these dependent variables when sorbents and foams were distributed on the HM slick versus a pure HM slick.
