Preliminary Assessment of Certain Beach Cleanup Techniques

📖 The Scoop

A study was performed to evaluate, in a controlled environment, the effectiveness of in-situ burning, sorbent techniques, a coating agent, a burning promoter and combinations thereof for protecting beaches or cleaning oil off contaminated beaches. The test program was carried out in British Columbia in the Vancouver area during January and February 1979. The location and time of year were selected to simulate the colder ambient temperatures that could be expected in the arctic and sub-arctic regions in the non-winter months. Fine gravel, sand and mud flat type beach soils were used in combination with two crude oils - one light-to-medium density and the other medium-to-heavy - as the primary parameters in the study. Thickness of the oil coating, position of the water table, and application of a burning promoter and a surface coating agent were the other main parameters in the program. The effectiveness of the burns was evaluated in terms of type of burn achieved (i.e., good, fair or no burn), type of residue left, additional depth of penetration of the oil in the soil due to the burn, and efficiency of the burn as determinded by comparing the amount of oil present before and after the burn.
