These types of treatment options are particularly attractive for decommissioning in situations where effluent loadings are low and flows seasonal. The effluent-cleansing processes are natural in passive systems, and are biologically-mediated. Wetland sediments are the most important aspect of these natural treatment systems.enpassive treatment systemswetland sedimentswaste waterdecommissioningmicrobial activitymuskeg sedimentsarsenicnickelseepage treatmentTechnical Report
