Permeable Reactive Barriers for Petroleum Hydrocarbons Compounds (PHCs)

Managing dissolved contamination along property boundaries or adjacent to sensitive receptors such as residential properties or streams has long been an area of focus for the environmental industry. Risk Control Measures are often required in conjunction with risk assessment or remediation. In the 1990s the permeable reactive barrier (PRB) was pioneered – an underground permeable "wall" which is a barrier to contaminants but allows the natural flow of groundwater to continue through the subsurface wall. The initial PRB used zero valent iron (ZVI), was termed the “Iron Wall”, and was very effective and widely applied for the treatment of chlorinated volatile organic compounds (cVOCs). Unfortunately the Iron Wall is ineffective for petroleum hydrocarbons (PHCs). For more than 20 years many attempts have been made at creating a PRB for the treatment of PHCs, but until recently each technique has had serious limitations. The purpose of this talk is to showcase a new in-situ Granular Activated Carbon (GAC) based technology which has been successfully used to treat PHCs (and cVOCs) along property boundaries. The technology is referred to as a “Trap and Treat” concept. Previously the use of GAC in the subsurface has been limited due to the limited adsorptive capacity of the GAC. However, a new technology (to Canada) allows for both the adsorption and the treatment of the dissolved PHCs. Thus passive PRBs can be installed to allow for PHC plume capture and treatment over a long period of time. This talk will present the “Trap and Treat” technology and describe how the technology can be applied along property boundaries, adjacent to streams, or along other sensitive receptors. A case study will also be provided. Additionally, other emerging PHC PRB approaches will be showcased, compared and contrasted to the use of the Trap and Treat approach. The talk will conclude with general recommendations on installation techniques for PRBs for PHC treatment.
