Businessman and environmental advocate Eli Fuller is calling for an investigation after alleging that thousands of gallons of waste oil were dumped into mangroves near the island’s landfill, contaminating Five Islands Harbour following recent heavy rainfall.

In a social media post, Fuller said he had previously warned that oil appeared to be entering the mangroves off the top of the landfill. After record rainfall earlier this month, he said he began receiving reports of oil visible in the harbour.

“Whenever plenty of rain falls oil finds its way to the sea, and yesterday I started receiving calls about large amounts of oil being in Five Islands Harbor,” Fuller wrote.

He described the situation as one of the worst environmental incidents he has witnessed, warning of serious cultural, environmental and economic consequences. Mangroves serve as critical nurseries for marine life and help protect coastlines from erosion.

Fuller said he visited the area and spoke with one of the remaining cockle fishermen, expressing concern about the impact on livelihoods in the Five Islands community.

He questioned how such dumping could occur, noting that security is stationed at the landfill and trucks are reportedly inspected before being directed to designated dumping areas.

“This kind of environmental crime should result in a court case where somebody pays for the incredible amount of destruction caused by dumping thousands of gallons of oil into one of our most important bays,” Fuller said.

He added that he is willing to work with the government to explore solutions but stressed the need for accountability.

Authorities have not yet publicly responded to the allegations.
