Water Services and Technologies, in conjunction with the Brazilian Groundwater Association – Núcleo Minas Gerais (ABAS-MG) and Hidrogeo, is pleased to offer this course focused on hydrogeochemistry principles and applications. The participant will have the opportunity to improve knowledge about environmental geochemistry, and its applications in the most diverse fields.

In this course, fundamentals and applied aspects of hydrogeochemistry will be addressed, related to the chemical composition and quality of groundwater. The main themes to be presented are:

  • – Introduction to hydrogeochemistry, geology applied to hydrogeochemistry, physical-chemical and biogeochemical processes in groundwater, hydrochemical classification and classification (Res. CONAMA 396/2008), and concepts of vulnerability and risk.
  • – Steps involved in a hydrogeochemical characterization / monitoring work: Definition of a monitoring program (legal and applied aspects), field and laboratory techniques, quality control and interpretation of results.
  • – Specific applied topics: Hydrogeochemistry in mining areas, acid mine drainage, transport of contaminants, hydrogeochemistry in karst environments and hydrogeochemical numerical modeling concepts.
  • – Practical exercise of hydrogeochemical data analysis using specialized software – Aquachem.

Ph.D in Mineral Resources and Hydrogeology; M.Sc in Geochemistry and Environment. Industrial chemistry. For 27 years he was Professor in the Undergraduate courses in Geology and Post-Graduate in Geochemistry and Environment at the Geosciences Institute of UFBA. Currently he works as a consultant in monitoring, classification and classification of groundwater, including working on UNESCO projects associated with the theme. For more than 20 years he has been instructor of numerous courses and lectures in other Universities, Organizations and scientific events, on Environmental Hydrogeochemistry, Groundwater Geochemistry and Contamination, Protection and Management of Groundwater, Quality of Water Resources in hydrographic basins, among others . Scientific activities include coordination and participation in several national and international projects, publications and book chapters related to the Quality of Water Resources, Hydrogeochemistry and Groundwater Monitoring.

Environmental Geochemist: Geologist, with 25 years of experience in the Area of Environmental Sciences and Engineering (Performance in the study of bioavailability of metals in sediments by the University of Delaware USA and impacts of arsenic in mining sites by UFMG and in a consulting company); master’s and doctorate from the Colorado School of Mines USA and postdoctoral from the University of Delaware and UFMG. Elaboration and development of more than one hundred studies on the transport of contaminants in groundwater, a model of the future quality of a cava lake, an industrial waste disposal mixture area and in project management that involve the elaboration of conceptual decommissioning plans for mining (Nexa Resources SA; Anglo Gold Ashanti and Vale – Águas Claras Mine). Strong performance in the technical area of management of contaminated areas including study of geochemical background, preliminary, confirmatory and detailed investigations in industrial sites in operation or already paralyzed. In 2009 he led the creation of the scientific technical entity SANAP (South America Network for Acid Prevention) whose main objective is to promote scientific discussion of the Acid Rock Drainage issue among research centers, universities, consulting companies and mining companies . Author of the book: Water Quality Assessment – Technological Basis for Environmental Management. In 2017 he worked as a consultant for Fundação Renova in the project to evaluate the quality of sediments and waters of the Rio Doce after Mariana’s accident.

Geologist graduated from Acadia University, with a master’s degree in geology focused on hydrogeochemistry from Simon Fraser University, Canada. He has 10 years of experience in hydrogeology and hydrogeochemistry projects, having worked in works related to mining, regional aquifers, natural and anthropic occurrence of metals and other solutes in groundwater, and use of hydrogeochemical and isotopic parameters in hydrogeological studies. He has solid experience in conceptual and numerical modeling of flow and transport. He received an award from the Geological Society of America for the quality and relevance of his master’s research, related to the mobilization of metals in groundwater. He is a member of the Water Services and Technologies consulting team, and also regularly teaches courses and webinars on numerical modeling, hydrogeochemical data analysis and interpretation of pumping tests.
