The water company is conducting an inquiry after millions of contaminated plastic beads were found on Camber Sands beach, sparking fears of a potential "environmental catastrophe".
The plastic pellets could cause severe harm on marine life, according to a local MP, with concerns that protected marine species, including seabirds, porpoises, and marine mammals, might ingest them and perish.
A local official suspects the pellets may have been released from a nearby water treatment centre and has sent a letter to the water company's chief executive, demanding an explanation.
This coastal area, located in the southeastern region, is one of England’s most beloved beaches, known for rare dune habitat and expansive areas of fine grains.
Local helpers have been working urgently to remove the beads, filling dozens of bags with the synthetic debris, but the scale of the contamination event is vast, and it is unlikely they will be able to remove all of them.
An expert from a environmental organization remarked recently, "This represents the most severe contamination incident I have ever witnessed. It is contaminated plastic. Marine animals will consume small plastic items once they are in the ocean; they will draw in microorganisms, they will appear edible, in essence."
"After ingestion, that’s it: they can’t get it out. They will remain buoyant. It will create a slick which draws in plunging seabirds."
The expert continued that the removal work have been draining. "Yesterday, I was out there cleaning it up. We are trying to really piece together the timeline and the story for this horrendous event. It’s terrible."
"They are so small that from a very long way off, the beach appears unaffected. But as soon as you approach closely, you see there are millions black pellets, nestled under seaweed. It’s an impossible task – helpers have been raking for days, and they will continue to rake, but we cannot remove every pellet. It is the most severe I have ever seen of a polluted beach."
The local MP, who joined the clean-up efforts, remarked, "The immense quantity of plastic beads that have appeared on this shore threatens an environmental catastrophe. These plastic items are lethal to marine life and wildlife, and we are observing more dead seals, fish and porpoises on the coast."
"Local residents are laboring diligently to clear away as many beads as possible, but it’s a race against time. Southern Water must urgently establish if their local wastewater plants could be the origin of these pellets, and I’ve requested to dedicate all available resources to supporting the clean-up operation in the interim."
These pellets are additionally hazardous to canines as they contain a significant amount of PAHs, which are recognized for carcinogenic properties, and they often contain harmful substances including heavy metals, metalloids, and bromine.
A spokesperson for Southern Water stated, "We are working closely with the regulatory body and local council to investigate the source of polymer pellets which have washed up on the shoreline. This investigation work is still in progress."
"The district council is leading the clean-up of the shore, using specialists with a specialized machinery to extract the pellets. We are also supporting with the clean-up."
"We have performed water-quality sampling on the beach, which has shown no impact to environmental water quality. These results has been provided with the district council and the Environment Agency."
Regulatory officials has been contacted for a statement.
