Practical Applications of Hydrogeochemistry: Analysis and Presentation of Hydrochemical Data

In this two-day course, participants will learn some fundamentals in the field of hydrogeochemistry, and will put these theories into practice by analyzing hydrochemical data in different ways using the tools available in the AquaChem software. The focus of the course will be on data management and the generation of interpretive graphs efficiently, and considering the chemical reactions that typically influence the composition of the water. The objective of this course is to provide the participant with the ability to go beyond the basics in obtaining relevant information from hydrochemical data.


  • – Fundamental concepts on hydrogeochemical reactions and water-rock interaction;
  • – Data management, analysis and generation of interpretative graphs in AquaChem;
  • – Quality control of hydrochemical data;
  • – Obtaining saturation and activity indexes using the PHREEQC model;
  • – Exercise: Database development and analysis using Aquachem.

Instructor: Rafael Cavalcanti de Albuquerque

Rafael Cavalcanti de Albuquerque works on projects in the areas of hydrogeology and hydrogeochemistry. He has extensive knowledge and experience in the interpretation of hydrogeochemical data and water isotopes, and in the development of hydrogeological numerical models. His master’s thesis, carried out in Canada, was focused on understanding the hydrogeochemical evolution and mobilization of metals in aquifers, having received an award from the Geological Society of America for the quality and relevance of the research carried out.
