For two decades, Andy Dinsdale has walked the southern English coastline searching for rare seeds carried across oceans. In the process, he has become a dedicated observer of coastal pollution. But nothing prepared him for what he and citizen science group Strandliners found in early November at Camber Sands: millions of black plastic pellets scattered across the beach.
The pellets, known as bio-beads, are used in wastewater treatment systems to support bacteria that break down pollutants. A mechanical failure at a treatment plant more than 35 miles away caused an estimated 10 tons of these beads to spill into the English Channel. Up to 650 million of them were swept into sand dunes, creeks and the nearby Rye Harbour Nature Reserve, one of the country’s most important coastal habitats.
Southern Water, which operates the facility, accepted responsibility for the October 29 incident and has begun extensive cleanup operations with contractors and local authorities. Volunteers joined the effort immediately, using household tools to sift through sand during the first days of recovery.
The company estimates that about 80% of the beads on the beach had been collected by November 11, though more may wash ashore with changing tides. Concerns remain about how long the remaining microplastics will persist in the environment.
