Primary and secondary effluents were analyzed for three WRRFs under dry conditions in Texas and Oklahoma for a suite of 95 CECs. For the study set of 95 CECs, 82 were detected above the corresponding minimum reporting limit (MRL) in the primary effluent. 14 CECs were not detected in any WRRF samples. 18 of the studied 95 CECs were fully (100%) removed by full-scale WRRF biological treatment. 64 of the 95 studied CECs were found to exist in the secondary effluent at residual concentrations above MRL.
