The persistence of pharmaceuticals, hormones, and household and industrial chemicals through a pure‐oxygen activated sludge, nitrification, denitrification wastewater treatment facility was evaluated. Of the 125 micropollutants that were tested in this study, 55 compounds were detected in the untreated wastewater, and 27 compounds were detected in the disinfected effluent. The persistent compounds included surfactants, fire‐retardant chemicals, pesticides, fragrance compounds, hormones, and one pharmaceutical. Physical‐chemical properties of micropollutants that affected partitioning onto wastewater solids included vapor pressure and octanol‐water partition coefficients.
