Sydney: Authorities in Sydney have revealed that the mysterious marble-sized balls that led to the closure of several Sydney beaches last week contained saturated acids, E. coli, and faecal bacteria. The discovery follows an earlier incident in October when similar debris appeared on the city’s coasts, stimulating widespread closures and a large-scale clean-up.
The Northern Beaches council demonstrated that the balls, which were first spotted on 14 January at popular spots like Manly and Dee Why, were collected and sent to the New South Wales Environment Protection Authority (EPA) for further testing. The council urged the public not to handle any of the balls and to report sightings to local authorities.
In addition to the harmful acids and bacteria, the balls were also found to contain volcanic rock pumice. The council is hopeful that the EPA’s analysis will identify the source of the debris, allowing them to prevent future occurrences and protect the region’s beaches.
Mayor Sue Heins emphasised the extent of the investigation, stating that, “We are continuing to execute regular inspections of our beaches and encourage the community to report any sightings.” The council has been actively cleaning up the debris from the harbour beaches this week.
The earlier batch of debris in October sparked alarm when it was initially mistaken for “tar balls.” Further investigation indicated a mix of substances, including cooking oil, soap scum molecules, blood pressure medication, pesticides, and even methamphetamine and veterinary drugs.
Scientists have compared the blobs to “fatbergs,” which typically form in sewage systems. Despite concerns, Sydney Water confirmed that the city’s water treatment plants were operating normally and that there were no comprehended issues with the waste systems.
