The French Broad River (FBR) serves as the home to several endangered species, raising concern due to the possible presence of endocrine-active compounds (EAC). Research shows that exposure to EACs in wastewater treatment plant (WWTP) effluent, namely phthalates, induces complications in reproductive physiology of fish and animals. Quantification of EAC concentration in WWTP effluent was conducted in Asheville, NC. Multiple phthalate monoester concentrations have been successfully detected in WWTP effluent above the LOD and LOQ, though the use of solid-phase extraction and a Shimadzu Liquid Chromatograph Mass Spectrometer-8040 (LCMS). Moving forward, metabolite concentrations acquired in WWTP influent will be compared to concentrations located in the effluent. This comparison will describe the effectiveness of WWTP removal of EACs, and increase awareness in the community for environmental sustainability. We hypothesize that processes within the WWTP might promote an increase in monoester concentration due to the cleaving of the glucuronide bond on phthalate glucuronide metabolites. Considering the WWTP makes use of a rotating biological contactor, the biofilm located on the surface of the contactors could be a prime location for glucuronide cleaving.
