Kirk Nordstrom is a world leading geochemist with research expertise in mine drainage and geothermal chemistry, arsenic geochemistry, thermodynamics and geochemical modelling. Kirk completed his PhD in 1976 and developed the first speciation code for acid mine drainage and subsequently he has made his career with the USGS over the last 45 years. He has an excellent publication record with more than 270 peer reviewed papers or chapters, and 2 books including ‘Geothermal Thermodynamics’ co-authored with Jim Muñoz, which remains a must have text for aspiring geochemists. There is often a seminal quality or completeness to his work that that sets it apart, and most academic papers written on mine drainages would be incomplete without one or two ‘Nordstrom, et al…’ citations.
Blair Douglas is the Global Practice Lead for Hydrology and Water for BHP Resource Engineering Centre of Excellence, a technical leadership role setting technical direction on water management across multiple commodities to lift capability and awareness of water related risks and challenges. Prior to this role he was BHPs technical lead for river remediation and recovery efforts at Samarco, Brazil. A hydrogeologist by training and with over 25 years’ experience in the mining industry, he has held technical and management roles at multiple operations in various countries and environments, specifically in the field of mine dewatering, pit slope depressurisation, mine water management and more recently in characterizing and managing regional and cumulative water resource impacts. He directed technical studies, water related approvals and Regulatory negotiations for BHP iron ore growth phase from 2009 to 2015. Prior to joining BHP, Blair worked as a consultant in Australian mines and the large copper and gold operations of Chile, Peru and Indonesia.
Bill Perkins is an environmental geochemist and analyst who has worked at Aberystwyth University, in central Wales for over 30 years. The university at Aberystwyth sits in the middle of the mid-Wales orefield; a lead/zinc mining area that was active during the 17th, 18th and 19th centuries. This abandoned mining area is characterised by circum-neutral metal mine drainage. During his time at Aberystwyth Bill has been the lead scientist on a number of projects investigating novel absorbers for mine waters within the mid-Wales orefield and beyond. These projects have investigated a wide range of materials including an EU project on dealginated seaweed, projects on green rust, fly-ash, steel-making slag and, more recently a UK government-funded project on the potential of biochar as a sustainable metal adsorber. In addition to the field trials of alternative adsorbers Bill has supervised students in laboratory experiments using cheap apatite-based materials to treat local metal mine drainage. Wales has a number of challenging mine water problems not least of which is the drainage from Parys Mountain on the Isle of Anglesey. This site, together with the Avoca mine site in Ireland have provided excellent natural laboratories for teaching students about AMD. In addition to the work on mine drainage Bill is also responsible for the analytical laboratories in his department and looks after a wide range of analytical equipment including ICP-MS instruments.

Plenary Speakers & Session Chairs
Dr. Christopher Weisener is a Professor at the University of Windsor Ontario. He is an established multidisciplinary researcher at the Great Lakes Institute for Environmental Research (GLIER) and is recognized for his contributions in the field of environmental geomicrobiology throughout the world. His research programs link multidisciplinary themes (i.e. microbiology, geochemistry and molecular ecology) within applied and fundamental research frameworks for habitat restoration. He specializes in developing cutting edge science which correlates contaminant stress with microbial community function in both terrestrial and aquatic systems. In particular his group focuses on the, mobility, cycling, and bioavailability of nutrients (e.g. carbon, nitrogen, sulfur and phosphorous) and toxic metals in soils/ aqueous sediments under fluctuating redox conditions. This information can be used to design sustainable solutions for waste and water management and ecosystem services.
He completed his PhD in Applied Science in geochemistry at the University of South Australia in Adelaide, Australia.
Prof. Andrea Gerson is the Managing Director of Blue Minerals Consultancy (BMC); Hon. Prof. Fellow, Dept. Physics, Melbourne University; Hon. Prof., Research School of Earth Sciences, Australian National University and Adjunct Professor, School of Physical Sciences – Centre for Ore Deposit Earth Sciences, University of Tasmania. She completed a PhD at Strathclyde University (Scotland) in 1990, followed by a post-doc at King’s College (London) until 1993, both focussing on n-alkane crystal structure. Prior to establishing BMC in 2015 she lead the Research Group, Minerals and Materials Science and Technology at the University of South Australia. She specialises in the relationship between mineral structure, reactivity and implications for environmental impact and remediation. She now applies and develops advanced analytical techniques for direct application to industrial environmental issues. Andrea has 200 publications, over 11,000 citations and an H-index of 43.

Associate Professor Mansour Edraki is a geo-environmental scientist specialising in the field of inorganic geochemistry. His research interest is in understanding and predicting the source, transformations and fate of contaminants, particularly acid and metalliferous drainage (AMD), in the mining environment. Through field monitoring, laboratory experiments and modelling he follows the geochemical pathways of heavy metals, metalloids (e.g. arsenic) and salts and investigates the natural processes that may degrade the quality of surface and groundwater and natural soils. Mansour uses that knowledge to quantify the extent of the current and future effects of those processes for optimum remediation and rehabilitation outcomes.
Associate Professor Edraki joined UQ in 2000 following completion of his PhD at University of New England. Prior to that, and before immigrating to Australia in mid 1990s, he was a lecturer in earth sciences. Since joining UQ, Dr Edraki has focused on developing innovative techniques for understanding and predicting geochemical processes which underpin sustainable management of mine waste and mine water, particularly acid and metalliferous drainage.
