Michael Verreault
Hydrogeologist – President
Michael Verreault holds a bachelor's degree in geological engineering and a master's degree in hydrogeology. Mr. Verreault's master's topic dealt with the protection of groundwater in a complex environment. The latter has developed particular expertise in tracing tests in underground and surface water and also with the use of numerical modeling by finite elements and differences. Being a hydrogeologist, Mr. Verreault has obviously carried out a multitude of underground water supply projects throughout the province of Quebec. He carried out the design and analysis of wells pumping up to 40,000 l/min and able to supply more than 60,000 people. In recent years, he has mainly worked in the mining sector, carrying out projects on a global scale. In particular, he adapted the profile tracing test method, which makes it possible to locate contrasting flow zones in a fractured rock environment. Mr. Verreault is a particularly pleasant person to work with and clients greatly appreciate his simplicity in carrying out small or large-scale projects. The latter is always looking for the best possible solution and offers innovative ideas that allow customers to save and optimize. The honesty and quality of the service offered remain his main concerns.
Thierno Bah
Director of Operations
Thierno BAH holds a master's degree in geology from the University of Starsbourg in France and an environmental engineering degree from the Agronomic Institute of Guinea. Thierno BAH's training is that of a geologist, with a good knowledge of geophysics. During his studies in Strasbourg, he learned to apply different methods of analysis and to work independently at the interface of different disciplines linking observations, data analysis and modelling. His Master's internship aimed to study the partition of elements of economic interest (Ni, Sc) within the alteration of laterites in New Caledonia. His work demonstrated a remarkable capacity for learning and an excellent knowledge in the fields of petro-geochemistry and geology in the broad sense. Over the past 7 years, Mr. BAH has successfully conducted fieldwork in mining hydrogeology in various underground sites or open pit mines in Canada, the United States and Mexico. He has also developed serious skills in data interpretation, database systems and 3D software such as Datamine Discover.

Considering Hydro-Ressources Inc. as his home, his mission is to contribute to its expansion throughout the world, more particularly in the African continent considered as a mining scandal. Amadou is a dedicated employee, in search of knowledge and has a concern for a job well done. Hydro-Ressources is blessed and proud to have him on its team.
Pier-Olivier Gilbert
EIT- Master's Student in Hydrogeology
Pier-Olivier holds a bachelor's degree in Geological Engineering from the Université du Québec à Chicoutimi and is currently pursuing graduate studies in hydrogeology. He joined the Hydro-Ressources team in May 2022, where he works as a field supervisor. Driven by curiosity and a desire to explore new horizons, he is a dedicated and valuable member of the company.
Jason Center, L.G
Field Geologist
Jason Center possesses a professional geologist license in the state of Washington, USA, and holds degrees in Geology and Environmental Science from Northern Arizona University. Jason’s academic background provides him with a comprehensive understanding of the natural sciences. His professional experience has centered around Geotechnical Engineering within the construction and mining sectors, as well as management of the mining lease program for public lands in Washington State. He has executed a diverse array of applied geologic tasks supporting numerous varieties of projects in field, laboratory, and office settings. Jason has a comprehensive understanding of the processes and principles that form the backbone of our work at Hydro-Ressources, Inc. Jason joined the Hydro-Ressources team in 2025. His work with Hydro-Ressources is focused on Hydrogeologic field testing at project sites internationally. He is a valuable contributor to these projects, demonstrating meticulous attention to detail, accuracy, efficiency, and adept problem-solving skills.
Valérie Vaillancourt
Numerical simulation and hydrogeological modeling
Valérie joined the Hydro-Ressources team in 2020. She specializes in numerical simulation and hydrogeological modeling. She uses FEFLOW to simulate groundwater flow and assess the impacts of mining activities. She is proficient with MapInfo Pro for geospatial data management, as well as Leapfrog Geo for building 3D models from borehole data. She creates precise technical plans using CorelCAD and AutoCAD. Valérie regularly interprets field tests (pumping, injection, tracing, etc.) and writes detailed technical reports. She also manages projects and budgets, delivering results that are rigorous and well presented. In parallel, she is pursuing continuing education in mining environment. Her work reflects strong expertise and scientific rigor. Outside of work, she enjoys playing tennis and running.
Cécile Fehr
Hydrologue
Cécile holds a bachelor's degree in Earth sciences and a master's degree specializing in natural hazards. His interests for the environment and water resources have led him to evolve within the Hydro-Ressources team for several years. She mainly works on themes in hydrology, hydrogeology and environmental expertise. Cécile is always ready to start a new project and delivers impeccable work on time. His professionalism is to his credit.
