Oleophilic bio barriers (OBBs) for control of hydrocarbon sheens at groundwater-surface water interfaces
Sheens are a common problem at petroleum facilities located adjacent to surface water bodies. Thin, iridescent films of Non-Aqueous Phase Liquid (NAPL) can form on surface water sporadically and unpredictably via three processes: seeps, ebullition, and/or shoreline erosion. Because the appearance of sheens can elicit a notice of violation of the Clean Water Act, a suite of remedies has been used to address them. Common remedies are often predicated on physical barriers and sorbent barriers, both of which can be expensive and/or prone to failure due to bypass and/or finite storage capacities. ...
