Per-and poly-fluoroalkyl substances (PFAS) are stable chemical compounds with multiple industrial uses, including as components in firefighting foams, nonstick cookware, food packaging, insecticides, and waterproof and fire-resistant fabrics. However, the stability that makes PFAS so useful also prevents them from breaking down readily.
CRC CARE is developing a National Remediation Framework (NRF) for remediating and managing contaminated sites. The NRF is designed to harmonise guidance and best practice in the remediation and management of contaminated sites in Australia, and builds on existing best practice and regulation.
