Overview

This analysis assesses PFAS and precursor transformations in wastewater, highlighting significant findings on effluent concentrations.

Key Points

  • PFAS concentrations in effluent ranged from 356 to 558 ng/L, revealing limited treatment efficiency across stages.
  • Total oxidizable precursor assays indicated PFAS levels increased twofold in influent and 1.5-fold in effluent samples.
  • Advanced analysis combined with USEPA Draft Method 1633 provided detailed insights into PFAS behavior and transformations.
  • Significant quantities of PFAS were found in sludge, posing risks for terrestrial redistribution through land application.
