The Gems of Water is a citizen engagement project for water quality monitoring. By challenging the typical roles of citizens and scientists, the project connects local groups concerned with water quality issues around the world to scientists, who provide methodological, technical and analytical support to monitor pollution caused by organic contaminants.The Gems of Water uses an advanced technique, the Stir Bar Sorptive Extraction (SBSE), to assess the occurrence of agrochemicals in surface and groundwater. The project is currently travelling to various locations, including Costa Rica, Kenya, Australia, Romania and Bulgaria.The project aligns with UN resolutions on monitoring water quality. It supports the World Water Quality Alliance in collaboration with the UN Environment Programme Global Environment Monitoring System for Water (UNEP GEMS/Water) collecting different types of data on water quality around the world.© European Union, 2025 The Gems of Water storiesDiscover stories and data from Costa Rica"In my case, at one of the points the extraction was complicated since the river changed and we could not reach it safely. Thanks to the help of a local, we were able to extract the sample from above a bridge with a fishing line. It was a beautiful experience. When there was something to solve, creativity was key to achieving it. Everyone's flexibility and enthusiasm was a plus. These insights will be valuable for future projects".- Maria, Coral ConservationDiscover stories and data from Kenya"I was motivated to join by my passion for advocating for conservation protection and proper management of freshwater sources in Kenya for the benefit of people and nature".– Enock, Kenya National Association of Water Resources Users AssociationDiscover stories and data from Bulgaria"The project is very valuable and gives the opportunity to evaluate the water quality for the content of substances with mini concentrations with a maxi effect on the biota. The project realizes the possibility of open and accessible science for citizens." – Anonymous participant, Sofia University "St.Kliment Ohridski"Discover stories and data from Romania"One of the most interesting aspects of the project was the interaction with people and giving them the opportunity to experience some aspects of analytical chemistry applied to environmental protection, which is what I experience every day. The fact of sharing their needs with our professional experience and of having achieved these results should make all project participants proud."- Giulio, EC-JRCDiscover stories and data from Australia"For LAWROC, it is a new experience to work so closely with European scientists on a project of this nature, we have engaged local scientists for testing in the past but your ability to enlist us in a citizen science project using EU standards for testing has been quite empowering for us. You have given us confidence to continue the citizen science path!”- Neil, LAWROC How to become a Gem of Water Citizens can receive a tool kit with instructions and protocols to become their own water scientists!
