portrait View Pierre D S Rousseau's profile on LinkedIn Pierre Rousseau is the Owner and Principal of Terrachem Pty Ltd. He has an M.Sc. in Geochemistry and more than 19 years' experience in environmental geochemistry and mine water and waste management. He has worked on several large, high profile, mining, power generation and industrial projects in Africa, Australia and Asia.

Pierre has carried out all aspects of geochemical assessment, including project management, sampling, data evaluation, geochemical modelling, reporting and communications. He has provided support for all stages of project development, from pre-feasibility to post closure. Pierre is affiliated with the Australian Insitute of Geoscientists (AIG) and is registered as an RPGeo for environmental geoscience and geochemistry disciplines. He is also a registered professional geoscientist with the South African Council of Natural Scientific Professionals (SACNASP) in the categories Earth Science and Environmental Science and has been an Associate Editor for the Mine Water & Environment Journal of the International Mine Water Association since 2015.

Pierre specialises in integrating geochemical, hydrological and geotechnical components of mining projects, to provide an understanding of factors affecting future water quality evolution or to explain current water quality. He has carried out or participated in assessments for several commodities, including coal, gold, iron ore, nickel, cobalt-copper, diamonds and uranium. He has also completed assessments of metallurgical waste, coal fired power station ash and flue gas desulphurisation residues, along with geochemical problem solving for engineering applications. He has extensive field experience and is proficient with several spatial and geochemical modelling software packages, along with other supporting software to provide the range of expertise required to contextualise geochemical data and develop relevant strategies within the relevant project environment. Pierre also has experience in environmental management, through acting as a Mine Environmental Officer early in his career and participation in a one year professional exhange programme in Germany on Environmental Management and Costing.

Pierre also has substantial expertise in geochemical mineral exploration in addition to his environmental geochemical specialist background. This diversity and range of practical experience is invaluable for the contextualisation and integration of geochemistry with other relevant disciplines and for communicating with other project personnel and stakeholders.
