PFAS in Biosolids: A Southern Arizona Case Study

Rationale for Study

PFAS are fluorinated compounds that comprise a family of anthropogenic chemicals used for decades to make products resistant to heat, oil stains, grease, and water. Of these, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been the most prominently used in the U.S. PFAS are now regarded by EPA to be “emerging contaminants”.

WA State General Permit for Biosolids

The Washington State Dept. of Ecology announced their determination that the general permit under WAC-173-308 is the best approach to implementing the statewide program. This is following a complete review of comments, of which Northwest Biosolids comments were included, on the preliminary notice to issue a revised general permit.

PFAS in Wastewater Resources
As the PFAS topic continues to evolve, new resources have also become available to help the water and wastewater sector better understand the weight of this on their programs.
