Interim Human Health Risk Assessment for RAAF Base Tindal and surrounding communities

05-Jan-2018 10:46 AM

The Department of Defence has released the Interim Human Health Risk Assessment (IHHRA) Report for RAAF Base Tindal.

The key findings of the IHHRA were presented at a community engagement event in December 2017.

The assessment was conducted as part of the detailed environmental investigation into per- and poly-fluoroalkyl substances (PFAS) on, and in the vicinity of, RAAF Base Tindal. This investigation is following a nationally agreed framework for the investigation of contaminated sites.

The IHHRA seeks to identify major pathways and risk-factors with the aim of informing future advice provided by government agencies and authorities on how to minimise risk from PFAS. This assessment informs the advice provided to the public by the relevant health, water and environmental authorities.

The findings of the IHHRA report were used to inform the Government’s decision on the $5.7 million Katherine Community Support Package, which was announced on 3 December 2017.
