Abstract

A method for controlling petroleum hydrocarbon (NAPL) sheen releases resulting from seeps, ebullition and erosion, on water surfaces, is described. An oleophilic bio-Barrier (OBBs), which may include a composite of hydrocarbon sorptive materials through which water is readily conducted, is placed at a groundwater/surface water interface (GSI) for promoting natural aerobic degradation of the intercepted/adsorbed NAPL through natural cycling of aerobic surface water and/or atmospheric oxygen. OBBs may be protected by structural covers (i.e., sand and rock gabions, as examples).
