“…Poor handling practices and the large volume of hydrocarbons required for operations has led to the contamination of these once pristine environments. A number of innovative approaches have been developed to remediate hydrocarbon-contaminated soil, water and source plumes in these areas including bioremediation, landfarming, landfills, containment barriers, biopiles and permeable treatment barriers (Van Stempvoort and Biggar, 2008;Snape et al, 2008;Paudyn et al, 2008;Kalinovich et al, 2008Kalinovich et al, , 2012Sancartier et al, 2009;Mumford et al, 2013Mumford et al, , 2014McWatters and Rowe, 2015).…”

“…Alternatively, Mumford et al (2014) reports a significant increase in the B63 mm fraction from GAC, indicating that freezeÁthaw accelerates particle break up. Mumford et al (2014) recommend the mixing of GAC with more robust materials (e.g., zeolites, sand) to ensure permeability and longevity of petroleum hydrocarbon capture in Antarctica and the Arctic.…”

“…While maintaining PRB media reactivity is important for the retention of petroleum hydrocarbons from groundwater, the most critical aspect of PRB performance is the maintenance of permeability (Mumford et al 2014). This is particularly relevant in the Antarctic and Arctic where materials are subject to freezeÁthaw processes (Gore 2009).…”

“…PRBs are one of the most practical technologies for onsite or in situ groundwater remediation in cold regions on account of their minimal energy, monitoring and maintenance requirements (Snape et al 2001;Mumford et al 2013;Mumford et al 2014). In a PRB, contaminated groundwater passively flows through a single or multiple compartments of reactive material wherein the contaminants are physically adsorbed or degraded by chemical or biological processes (Gore 2009;Yeh et al 2010;Camenzuli et al 2013).…”

“…The composition of MPRB materials for remediation of groundwater heavily contaminated by a mixture of heavy metals (Cd, Cu, Ni, Pb, Zn) using different layers of activated carbon (GAC), zeolite (Z) and zero-valent iron (ZVI) basing on laboratory test results and literature [16,29,30] was determined. In groundwater contaminated by mixtures of heavy metals (e.g., Cd, Cu, Ni, Pb, Zn), several processes such as sorption, ion-exchange, reductive-oxidative degradation, reduction and/or precipitation processes offered by ZVI, GAC, and zeolite may be used [8,31,32].…”

Abstract. Permeable reactive barriers (PRBs) are employed as in situ groundwater remediation technology. The installation of PRBs is usually a major investment, where one of the biggest cost drivers are material costs. PRBs are barriers against contaminants moving under the natural gradient, however not against groundwater contaminants. The most common construction of a PRB is a single barrier, but in the case of contaminant mixtures a multi-layered construction, i.e. a combination of different reactive materials and removal processes, is required. The most important parameters for PRB design are dimensions. The barrier must be long enough to treat the entire width of the plume (dimension perpendicular to groundwater flow) and should extend to and be keyed into an impermeable layer. The problem is to determine the optimal thickness of a PRB, which should provide a residence time appropriate for reducing the concentration of contaminants to the desired effluent concentration. In PRBs, design is accomplished using numerical methods or simulators, which are useful to predict the scenarios and evaluate the resulting groundwater flow systems to specific site conditions. On the other hand, numerical methods are complicated and may have significant errors if the discretization is too coarse or is incorrectly aligned. This paper deals with a simple, conceptual model of a one-approach optimization method for multi-layered PRB design. Based on literature and laboratory test results (residence time, density and hydraulic coefficient), a selection of layers of reactive materials was determined. Considering the lowest cost of the reactive materials, the required thicknesses of activated carbon, zeolite and zero valent iron were calculated using two different algorithms. The simple model may be used for preliminary barrier design and cost calculations. Using the optimization model in a preliminary design stage, it is possible to reject the PRB concept and avoid losing time for the complicated analysis.
