Abstract

The legacy effect of contaminated land is a widespread issue, even in remote, polar regions such as Antarctica. Despite the management and remediation of contaminants attracting significant scientific attention in temperate environments, there remains a limitation of successfully trialled technologies suitable for implementation at metal contaminated sites in cold climates. In response, various new and innovative technologies applicable to metal contaminated sites are being developed. These technologies can generally be applied in-situ and are feasible and effective for the long-term management of contaminants despite the logistical constraints associated with working in polar environments such as Antarctica.

Several technologies are currently being adapted to and trialled in polar environments. This research focuses on the application of orthophosphate chemical fixation, silica microencapsulation technologies and permeable reactive barriers at Casey Station, Antarctica. Orthophosphate fixation reduces the environmental harm posed by metal contaminants in soil by transforming metals into inert, non-bioavailable metal-phosphate minerals, whereas encapsulation technologies contain metals in a microscopic silica coating and prevent migration of contaminants to surrounding soil strata. Permeable reactive barriers are a passive barriers installed in-situ technology and are being developed to remediate contaminated groundwater. These technologies have independently demonstrated their effectiveness for the management of metal contaminants and show potential for larger-scale remediation operations when used simultaneously.
