The University of Coimbra researchers participated in the “Water – an Unfiltered exhibition” and showcased the development of their H2OforAll project. The exhibition aimed to raise awareness about the basic right to drinking water, using science, technology, and the collective commitment of all of us. It invited visitors to explore various aspects of the availability and use of this vital resource in a positive and engaging way. This exhibition was held as part of the International Decade for Action on Water for Sustainable Development and is aligned with United Nations Sustainable Development Goal 6, which aims to ensure water and sanitation for all by 2030. Visitors were able to witness how the innovative technologies developed through the H2OforAll project will help prevent, monitor, and decontaminate drinking water, ensuring the highest quality for our consumption.
