A new assessment of water quality in the Caribbean Netherlands identifies significant concerns related to nutrient pollution and chemical contaminants in Bonaire’s coastal waters. The Bonaire Nature Platform (BNP) agrees with the findings of the report and calls for urgent action to address the sources of pollution threatening the island’s communities and marine ecosystems.
The study, conducted by Wageningen Marine Research in collaboration with STINAPA Bonaire, Reef Renewal Foundation Bonaire (RRFB), and other local partners, is the most comprehensive water quality assessment undertaken in the Caribbean Netherlands to date.
The findings show that many of the pressures affecting Bonaire’s marine environment originate on land, including wastewater, stormwater runoff, erosion, and other forms of pollution that are entering the sea and negatively affecting water quality.
“Water quality is closely linked to many of Bonaire’s environmental challenges,” the Nature Platform states. “Addressing pollution will also support efforts related to erosion control, wastewater management, habitat restoration, climate resilience, and sustainable development.”
The report found that nutrient levels in Bonaire’s coastal waters frequently exceed levels considered healthy for coral reefs. Excess nutrients stimulate algal growth, reducing the ability of corals to survive and recover. Excess nutrients and chemical pollution combined with increasing ocean temperatures and recurring bleaching events further reduce reef resilience.
Healthy coral reefs are not only important for nature, but also for Bonaire’s economy. They support fisheries, attract visitors from around the world, and help protect Bonaire’s coastline.
Scientists conclude that reducing local sources of pollution is one of the most effective actions available to improve the long-term health of Bonaire’s reefs.
The report also identified elevated levels of several harmful chemical contaminants in marine sediments. These pollutants can accumulate in marine organisms and potentially enter the food chain, highlighting the need for further research into possible impacts on human health and marine life.
The Bonaire Nature Platform also calls for stronger action to address pollution at its source, including improvements to wastewater and waste management infrastructure, enforcement against illegal dumping, compliance with environmental legislation, and action against globally banned harmful chemicals. On Bonaire, priority should be given to addressing contamination associated with the BOPEC site and the areas around Lagun.
The BNP would like to see a structurally funded water quality monitoring and assessment program for the Caribbean Netherlands, including clear standards, binding thresholds, compliance assessments, and predefined management responses. It also calls for continuation and expansion of additional biological monitoring to determine whether contaminants are accumulating in marine organisms and seafood species, allowing
environmental and human health risks to be assessed more regularly.
“The science is clear,” the Nature Platform states. “Improving water quality is essential for healthy ecosystems, sustainable tourism, fisheries, and the wellbeing of our community. The findings
should serve as a call to action and an opportunity to invest in Bonaire’s future.”
