NSW regulator confirms presence of harmful PFOS chemical in Belubula River

The New South Wales Environment Protection Authority (EPA) has confirmed the presence of perfluorooctane sulfonate (PFOS), a harmful "forever chemical," in the Belubula River. PFOS levels were found to be toxic to aquatic life but below safe limits for human consumption. The EPA is investigating the source of PFOS contamination, which may be linked to local industries. Recent testing showed PFOS levels decreased from earlier samples, but foam in the river remains a concern. The EPA plans to conduct further sediment and soil testing. The National Health and Medical Research Council is proposing stricter drinking water guidelines for PFAS chemicals, including PFOS. Public submissions on these guidelines will close on November 22, and a federal ban on certain PFAS variants will take effect in July 2025.
