What is the situation at Westleigh?

The NSW RFS has identified locations where PFAS foam has been used in significant quantities as part of firefighting training. One of these locations is the Westleigh training site 12 Warrigal Drive, Westleigh.  

The site is owned by Hornsby Shire Council and used by the NSW RFS. The site has been used as a training facility for many years by NSW RFS members.  

Following an initial inspection and limited soil sampling at the site by the EPA, the NSW RFS engaged an environmental consultant, Arcadis, to conduct limited baseline testing for PFAS in soil and groundwater on-site, and in groundwater and surface water off-site.  

PFAS was detected in soil on-site and in groundwater up-gradient and down-gradient of the site.

The presence of PFAS in the environment does not necessarily mean there is a human health risk. It is also important to assess if there are pathways through which people might be exposed to PFAS. For example, exposure via extraction of groundwater on or offsite for drinking or other domestic use is unlikely as the area is serviced by ‘town-water’ from the Sydney Water supply.

What happens now?

The NSW RFS is working with the Environment Protection Authority and Hornsby Shire Council to investigate the extent of any PFAS contamination on the training site and off-site in the surrounding area.

A preliminary site investigation by the consultant has identified pathways through which NSW RFS members and local residents may come into contact with these chemicals.

Over the coming months, there will be detailed testing in and around the training area of:

  • soil
  • surface water and sediment in drains, ponds and dams, and surrounding creeks; and
  • groundwater.

What should you do in the meantime?

Wait for the results of the detailed testing. The detailed testing will assist in determining the extent of the contamination, and any pathways through which RFS personnel and volunteers, and residents might be exposed to PFAS.
