NSW EPA releases PFAS Decision Tree – October 2016

The NSW EPA is implementing a state wide strategy to identify facilities in NSW where the past use of per- and poly-fluorinated alkyl substances (PFAS) may have resulted in site contamination.

This strategy includes an initial screening of sites, particularly focusing on whether the chemicals are present in soil or water. A decision tree has been developed to assist in the evaluation of the preliminary results for site prioritisation. This includes the use of trigger points to assist in the screening of data. Detailed investigations, if warranted, will be undertaken in accordance with appropriate contaminated land guidelines.

The decision tree will be reviewed following the release of national guidance on PFAS.
