“…The notion of injecting remediation amendments into contaminated sediment has been previously researched by Cantrell et al (1997) and Cable et al (2005). Both of these research groups attempted to develop a delivery method that would inject particulate amendments as a slurry into the sediment.…”

While the techniques and technologies associated with contaminated sediment remediation are relatively mature, there are several issues associated with these practices that make them unattractive. The inability of currently used mechanical mixing implements to place amendments in aqueous environments and their intrusive behavior toward benthic communities are just two examples of a necessity for an improved delivery method. Waterjets may be a viable option for placement of particulate remediation amendments, such as activated carbon and granular iron, at depth. A custom waterjet nozzle and injection system has been fabricated by the authors to examine this delivery concept. The developed injection system's performance was tested by characterizing the waterjet-delivered amendment (activated carbon and granular iron) distributions in a surrogate sediment. The delivered amendment distributions followed similar patterns for a range of injection times and a variety of amendments. The injection depths, however, were dependent upon the type of amendment being injected. These findings have led to a better understanding of what occurs during an amendment injection, which can be used for a more controlled placement of remediation amendments using this technique in the future. The laboratory results indicate that the subject waterjet system may have the potential for field-scale applications, especially for granular iron delivery, as the authors were able to place between 60 and 70 wt percent into a surrogate sediment bed along the path of injection.

“…11.6.4.2.2.4.5.1 Permeable reactive barriers Permeable reactive barriers include reactive filter beds containing zero-valent iron (Fe 0 ), phosphate rock (apatite), silica sand, and organic materials (EPA, 1999c). The barriers can be installed by digging a trench in the flow path of a contaminated groundwater plume and backfilling with reactive material or injecting either a suspension of colloidal material or a solution containing a strong reductant (Abdelouas et al, 1999;Cantrell et al, 1995Cantrell et al, , 1997. The reactive filter material is used to reduce and precipitate the uranium from solution while allowing the treated water to flow through the reactive bed.…”

“…It also decreases the aggregation of the iron particles while increasing their sedimentation time (Comba and Sethi, 2009). The viscosity increase can be achieved using special polymers with shear thinning properties such as guar gum or xanthan gum (Cantrell et al, 1997a(Cantrell et al, , 1997bComba and Sethi, 2009;Comba et al, 2011a;Dalla Vecchia et al, 2009;Oostrom et al, 2007).…”
