Per- and polyfluoroalkyl Substances (PFAS) represent a large range of chemicals that science is only beginning to understand with respect to their persistence, bioaccumulation, toxicity and mobility in the environment.  There are presently no Australian health-related guidelines or Trigger Points for Investigation (TPI) for PFAS that specifically apply to recycled water used for agricultural irrigation.

The objective of this project was to develop TPI for PFAS in recycled water for the protection of stock feed and human crops. The PFAS Exposure Model for Irrigation (PEMI) was developed to access the exposure of PFAS to animal feed and human crops irrigated with recycled water.
