To: Manus Mine environmentalists, Manus river communities whose rivers may potentially be impacted by sediments from upstream mining activities, Manus DEC scientists, and interested Manus environmentalists. The Secretariat of Science Research and Technology has sponsored a Conference next week from Mon 17th Nov to 21st Nov at UPNG. One of the four pillars is Responsible and Sustainable Environmental Development. At this forum, I will be presenting a paper on a model which I have developed to track mine derived sediments in rivers. I call this model the TRACER. The presentation will be next Wednesday 19th Nov 1:10 pm - 1:30 pm, Science Lecture Theater, UPNG. If interested to listen in, I will most welcome your presence. Presentation to CSIRO scientists such as Chief Scientist Dr. Graeme Batley and Geomophologists such as Dr. Geoff Pickup have withstood their scientific scrutiny. An abridged version of my Abstract is as follows: TRACER: A Geochemical Tracer for Responsible and Sustainable Environment Monitoring of Mine Derived Sediments Before, During and After Mine Closure. The sight of suspended sediments and riverbed aggradation in rivers that receive mine wastes are the most tangible and emotive legacy of any mining operation. Impacted and perceived impacted riparian communities of these rivers often want to know of transport, extent and duration of mine derived sediments in their rivers. TRACER is a geochemical model which promises to address such queries. This author developed TRACER (which stands for Tracking Riverine Anomalous Congeners by Enrichment Ratios) to trace mine derived sediments in impacted rivers. TRACER analyses enrichment ratios and relative abundance of congener elements in the mine derived sediments (MDS) then compares these ratios against geochemical signatures of regional control streams. Transport, extent and duration of MDS can qualitatively be determined by graphical observations of extent of decay of MDS giving way to domination by control stream sediments. This paper demonstrates application of TRACER at three PNG mines. In order to promote sustainable and responsible M&E, the author proposes to align TRACER with World Bank’s principle of “Participatory Monitoring and Evaluation Involving Primary Stakeholders”.
