Fijians are ingesting microplastics through everyday drinking water, according to new research by The University of the South Pacific (USP), raising fresh concerns about water safety and public health.
The study, released to coincide with World Water Day 2026, provides the first baseline evidence of microplastics in Fiji’s drinking water systems.
“Our findings show that people of Fiji are ingesting microplastics through drinking water, and this highlights the need for enhanced monitoring, treatment and public awareness to safeguard both people and ecosystems,” said Associate Professor David Rohindra, who led the research.
The study analysed multiple water sources, including tap water, groundwater, rainwater and bottled water, and found microplastic particles present across all categories.
Tap water recorded concentrations ranging from 0.10 to 2.90 particles per litre, while some bottled water samples contained up to 2.20 particles per litre. Rainwater showed the lowest levels of contamination.
Although the levels remain below critical pollution thresholds, researchers say the findings present a critical opportunity for early intervention.
“This is not a cause for panic, but a window for action,” Associate Professor Rohindra said.
The research comes amid growing global concern over microplastics, which have been detected in environments ranging from oceans to human bodies.
Beyond environmental concerns, the study highlights social impacts, particularly on women and girls in Pacific communities who often bear the responsibility for securing and managing household water.
“When water is unsafe, it is often women who must find alternatives, treat water and care for those affected,” Rohindra said.
Researchers say improving water quality could therefore directly support gender equality by reducing this burden.
The findings also point to broader regional challenges, including increasing urbanisation, limited waste management systems and the vulnerability of Pacific water sources to plastic pollution.
USP is now calling for microplastics to be included in routine water quality monitoring and for stronger collaboration between governments, utilities and communities.
The research team is also exploring innovative solutions, including the development of a low-cost hydrogel made from waste crab shells that could help remove microplastics from water.
The study adds to global calls for further research into the health impacts of microplastics, while reinforcing the importance of protecting water resources to safeguard both people and the environment.
