Unpacking PFAS NEMP 3.0 for beneficial reuse of biosolids

Welcome to our online event where we delve into the complexities of reusing biosolids contaminated with PFAS. Join Professor Paul Nathanail, as we discuss the PFAS NEMP 3.0 for beneficial reuse of biosolids.

Summary

* Introduction to Biosolids

* How the NEMP 3.0 criteria for (PFOS + PFHxS) and PFOA were derived

* Choosing a margin of safety (MoS)

* How the criteria can be used to calculate contaminant limiting biosolids application rates (CLBAR)

* What to do about other PFAS

* Jurisdictional differences across Australia

Biosolids are stabilised organic solids derived from the treatment of municipal sewage. They comprise nutrient-rich materials that can be used to fertilize or otherwise benefit agricultural soil including for meat, milk and fodder production.

Biosolids can contain PFAS, and other contaminants, resulting in potential ecological and/or human exposure. The PFAS NEMP 3.0 provides guidance for all jurisdictions to incorporate within their existing biosolids management frameworks. The PFAS NEMP 3.0 includes criteria for (PFOS + PFHxS) and PFOA for beneficial reuse of biosolids and provides a framework for deriving criteria for other PFAS, including precursors such as diPAP. Subsidiarity, a thread running through NEMP 3.0, may result in limits on other PFAS or allow beneficial reuse at concentrations above the criteria.

Demonstrating biosolids can be applied to a specific site involves showing PFAS concentrations in biosolids are below threshold concentrations and in-situ soil concentrations are below the laboratory limit of reporting OR showing the calculated contaminant limiting biosolids application rate (CLBAR) will provide nutrient benefit to the crop. Margins of safety can help account for uncertainties in calculations of CLBAR, exposure from pathways not considered and exposure to PFAS other than (PFOS + PFHxS) and PFOA.
