PhD opportunity in hydrogeology and geochemistry at Université du Québec à Montréal (UQAM) , Montréal, on the quantification of groundwater vulnerability in river bank filtration systems in Québec . The project focuses on understanding surface water infiltration dynamics, water travel times, and flowpaths toward exploitation wells in river bank filtration contexts. Research activities include field and laboratory work using isotopic tracers , geochemical tracers , and dissolved gas analyses with the miniRUEDI field mass spectrometer. The research environment is the CHAIRE UNESCO en changements environnementaux à l'échelle du globe in the Department of Earth and Atmospheric Sciences at UQAM, with international collaboration involving the University of Oulu in Finland. Funding: 3 years of funding are mentioned. The post does not specify a stipend amount, but it is presented as a funded PhD project. Eligibility: candidates should have an M.Sc. and/or engineering degree in hydrogeology and/or geochemistry, relevant laboratory experience, and strong fieldwork skills. Experience in isotopic geochemistry, environmental tracers, hydrochemical/isotopic analyses, or hydrogeological modelling would be an asset. Start date: September 2026. How to apply: send your CV, cover letter, and academic record to Antoine Picard at [email protected] . More information is available via the linked project page. This project aims to improve the protection and long-term sustainability of drinking water resources in Québec under changing hydroclimatic conditions.

PhD opportunity in groundwater vulnerability , hydrogeology , geochemistry , and environmental tracer analysis at Université du Québec à Montréal (UQAM), Canada . The project, titled “Quantification of the vulnerability of groundwater in river bank filtration in Québec” , focuses on river bank filtration (RBF/BF) systems and how surface water infiltrates aquifers and reaches pumping wells. The research aims to develop innovative tracer approaches to quantify infiltration dynamics, response times, and flowpaths in Québec, with direct relevance to drinking water protection, climate resilience, and source-to-tap management. Research activities include field tracer experiments and laboratory development/testing of analytical methods. The project will use isotopic tracers such as δ²H and δ³⁷Cl, and geochemical tracers such as Br, noble gases, and SF₆. A key component is the use of miniRUEDI, a field mass spectrometer for dissolved gas analysis. Field campaigns will cover urban, industrial, and agricultural settings. The PhD will be carried out within the UNESCO Chair in Global Environmental Change at UQAM’s Department of Earth and Atmospheric Sciences in Montréal, with international collaboration planned with the University of Oulu, Finland. Funding: 3 years of funding from MELCCFP and Fonds Bleu. Start date: September 2026. Eligibility: M.Sc. and/or engineering degree in hydrogeology and/or geochemistry; relevant laboratory experience in hydrochemical and isotopic analyses; proven fieldwork experience; knowledge of isotopic geochemistry, environmental tracers, and hydrogeological modelling is an advantage. How to apply: Send your CV, cover letter, and M.Sc. academic record to Dr. Antoine Picard at [email protected]. More details are available via the project link.
