The Center for Environmental Studies in Cienfuegos (CEAC) is set to embark on a research project sanctioned by the International Atomic Energy Agency (IAEA) to examine the presence of microplastics in Cuba's groundwater. This initiative was reported by the Cuban News Agency last Wednesday, referencing the Network of Cuban Communicators (RECNUC).
This project is part of the IAEA's Coordinated Research Project F33032, officially launched in early October 2026 and scheduled to run until 2030. Cuba joins eight other nations in this effort: Argentina, Brazil, Cameroon, France, India, Morocco, Sweden, and Tunisia.
The full title of the Cuban agreement is "Development of an Integrated Methodological Framework Combining Isotopic Hydrology, Environmental Tracers, Hydrogeochemistry, and Microplastics Analysis to Assess Sources of Contamination, Transport Pathways, and Environmental Fate in Cuban Groundwater Systems," as detailed by the Cuban News Agency.
Engineer Anamary Acosta Valladares, identified as a Research Candidate, will lead the scientific efforts on behalf of the CEAC.
Scientific Goals and Approach
"The project will allow us to merge isotopic hydrology, environmental tracers, hydrogeochemistry, and microplastics analysis to determine the origins of these contaminants in Cuban groundwater, their transport mechanisms, and ultimate fate," explained Acosta Valladares.
The initiative will begin with gathering existing data on groundwater quality, the presence of microplastics, and other pollutants. Subsequently, sampling sites will be pinpointed, and a monitoring program will be established.
The Process and Expected Outcomes
Samples will undergo quality-controlled testing at the CEAC's Environmental Testing Laboratory to ascertain contaminant composition and water origin. The findings will also enable analysis of microplastic degradation processes and their relationship with groundwater recharge and movement, paving the way for scientific publications and technical guidelines.
It’s crucial to note that this project is not based on confirmed groundwater contamination in Cuba or any identified health risks; it is a scientific monitoring and research venture in a field where, according to the IAEA, the sources, transport mechanisms, and impacts of microplastics in aquifers "remain poorly understood due to methodological limitations and lack of standardized approaches."
Background and Broader Implications
The CEAC has prior experience in this domain. In 2020, the center detected microplastics in the Bay of Cienfuegos, recording 49,562 particles per cubic meter during the dry season. In May 2026, they announced a project to study microplastics in marine organisms using nuclear techniques and participated in a study on sediments from the Almendares River and Havana Bay, published in the Marine Pollution Bulletin.
While this new contract F33032 focuses on groundwater—a less explored environment compared to marine or surface systems—Cuba, on a national scale, has documented over 2,200 sources of water contamination from industrial, agricultural, and urban activities. This underscores the importance of having surveillance data on the nation's aquifers.
The international project aims to produce harmonized sampling and analysis protocols, a global database on microplastics and isotopes, and case studies from pilot sites that enhance the technical capabilities of participating countries.
Understanding Microplastics and Their Impact on Groundwater
What is the main objective of the IAEA project in Cuba?
The primary goal is to investigate the presence and impact of microplastics in Cuban groundwater and to develop methodologies for assessing sources, transport pathways, and environmental fate.
Why is this research significant for Cuba?
Given the documented sources of water contamination in Cuba, such research is crucial for understanding groundwater quality and ensuring environmental protection.
How will the findings of this project be used?
The results will be used to analyze microplastic degradation processes, contribute to scientific publications, and develop technical guidelines for better environmental management.
