About the report

This report combines three recent outputs associated with the following ARRTC (Alligator Rivers Region Technical Committee) Key Knowledge Need (KKN): Develop a conceptual model of the ARR system (including the uranium mines) and reassess and quantify contaminant movement within the biophysical pathways.

Section 2 represents a Discussion Paper prepared for the 11th Meeting of ARRTC on 17-19 February 2003. This paper discusses the initial efforts to address the above KKN and places the issue of mining in the Alligator Rivers Region (ARR) within a landscape context, highlighting the multiple pressures acting on the region.

Section 3 represents a Discussion Paper prepared for the 13th Meeting of ARRTC on 15-16 March 2004. This paper provides further context and background of the above KKN and represents the progression of the associated tasks/activities introduced in the previous Discussion Paper (Section 2). It also outlines the proposed process to complete the activities associated with addressing the KKN.

Section 4 represents a PowerPoint presentation presented at the joint CSIRO and Land & Water Australia workshop on Contaminants and Ecological Risk Assessment, in Adelaide, 5-7 April 2004. The purpose of the presentation was to communicate the importance of conceptual models in risk assessment and to seek feedback and suggestions for improvement on the approach being adopted for the development of the conceptual model for contaminant pathways at Ranger.
