International Conference on Offshore Freshened Groundwater – Kalkara, Malta 18-20 May 2026

The Management Committee of the OFF-SOURCE COST Action (CA21112) is delighted to announce its final conference. This event is the main dissemination hub for our network, uniting leading researchers, industry professionals, policymakers, and early-career investigators to share the latest advancements in the study of Offshore Freshened Groundwater (OFG). Together, we will foster new collaborations, explore the culmination of four years of work, and chart the future for this promising unconventional water resource. We look forward to you joining us to shape the next chapter in OFG research and application.

Objectives

This conference seeks to:

• Disseminate of the key findings and outcomes of the OFF-SOURCE COST Action
• Connect a diverse community of scientists, engineers, water managers, and policymakers.
• Expand the OFG network by fostering collaboration between academic and non-academic partners.
• Define future research priorities and pathways for the sustainable use of OFG resources.

Themes

The scientific program is organized around four key themes reflecting the OFF-SOURCE Working Groups.

Mapping and Characterizing Global OFG Systems

Exploring the fundamental understanding of OFG through data compilation, literature synthesis, and database development. Contributions highlighting the extent, volume, and hydrogeological context of OFG bodies in Europe and beyond are welcome.

Innovative Methods and Technologies for OFG Exploration

Presenting cutting-edge tools for OFG detection and analysis, including geophysical surveys, geochemical methods, hydrogeological modelling, and integrated interpretation of multidisciplinary datasets.

From Resource to Reality: Utilization, Economics, and Feasibility

Bridging science and application by examining the technological, economic, and practical feasibility of OFG as a potable water source. Case studies, industry collaborations, and economic models are encouraged.

Sustainable Management and Governance of OFG Resources

Addressing environmental, legal, and policy challenges for long-term OFG sustainability. Topics include responsible abstraction, environmental impacts, and governance frameworks.
