NACWA, in partnership with the National Council for Air and Stream Improvement (NCASI) and the American Forest and Paper Association (AF&PA), is pleased to share with members a new report prepared by Stone Environmental detailing a more thorough “how-to” guide to understanding how the Pesticide Root Zone Model (PRZM) may be used to screen for PFAS potentially leaching into groundwater from land applied residuals and
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”.
Washington State Department of Ecology (Ecology) has requested comments on their draft PFAS Draft Chemical Action Plan (CAP). This CAP includes a variety of chapters, one of which is on biosolids. To review the CAP and provide comments, visit the PFAS CAP website. The comment period has been extended to January 22, 2021.

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.
