| Abstract | The primary objective of EPAs Nine POTW Study (the Study) was to investigate the occurrence of Contaminants of Emerging Concern (CECs) in untreated and fully treated wastewater at publicly owned treatment works (POTWs). EPA also initially investigated the occurrence of conventional, non-conventional, and toxic pollutants, including many of the pollutants in EPAs 1982 50-POTW Study (EPA, 1982). For the first four POTWs in this Study, EPA selected facilities that treated industrial discharges because POTWs receiving significant volumes of discharges from pharmaceutical or other manufacturing facilities might be expected to receive a significant quantity and variety of CECs. |

| Contents Notes | "The primary objective of EPA's Nine POTW Study (the Study) was to investigate the occurrence of Contaminants of Emerging Concern (CECs) in untreated and fully treated wastewater at publicly owned treatment works (POTWs). EPA also initially investigated the occurrence of conventional, non-conventional, and toxic pollutants, including many of the pollutants in EPA's 1982 "50-POTW Study" (EPA, 1982). For the first four POTWs in this Study, EPA selected facilities that treated industrial discharges because POTWs receiving significant volumes of discharges from pharmaceutical or other manufacturing facilities might be expected to receive a significant quantity and variety of CECs ... This report presents the findings from the Nine POTW Study for informational purposes. Caution should be used in interpreting the results. For several reasons, the study does not lend itself to national conclusions. The Study had two very distinct stages, each with different analytical methods, sampling techniques and POTW selection criteria. The nine POTWs in this study are not statistically representative of all POTWs in the country, nor would they be expected to statistically represent particular subpopulations of POTWs. The analytical methods were under development during much of this study, which resulted in certain data quality issues during laboratory analysis. Additionally, sample collection efforts were not designed to calculate removal of CECs from POTWs. Although some reduction in concentration levels of many CECs was observed in the effluent, the data are not sufficient to draw any conclusions about treatment effectiveness."--Introduction. |
