Fate of Sulfamethoxazole, 4-Nonylphenol, and 17β-Estradiol in Groundwater Contaminated by Wastewater Treatment Plant Effluent

Fate of sulfamethoxazole, 4-nonylphenol, and 17beta-estradiol in groundwater contaminated by wastewater treatment plant effluent.

Organic wastewater contaminants (OWCs) were measured in samples collected from monitoring wells located along a 4.5-km transect of a plume of groundwater contaminated by 60 years of continuous rapid infiltration disposal of wastewater treatment plant effluent. Fifteen percent of the 212 OWCs analyzed were detected, including the antibiotic sulfamethoxazole (SX), the nonionic surfactant degradat...

Pharmaceuticals in Wastewater Treatment Plant Effluent Waters

Pharmaceuticals are being used at an increasing rate, and end up in wastewater through excretion and disposal. They also end up in the effluent water of wastewater treatment plants because they are not specifically designed for pharmaceutical removal. Several studies suggest diverse negative effects on aquatic life that are exposed to these trace amounts of pharmaceuticals in their habitats. Th...

Demasculinization of male fish by wastewater treatment plant effluent.

Adult male fathead minnows (Pimephales promelas) were exposed to effluent from the City of Boulder, Colorado wastewater treatment plant (WWTP) under controlled conditions in the field to determine if the effluent induced reproductive disruption in fish. Gonadal intersex and other evidence of reproductive disruption were previously identified in white suckers (Catostomus commersoni) in Boulder C...

Occurrence and fate of emerging pollutants of 17beta-estradiol and testosterone in hospital wastewater and effluent: The effect of activated sludge and chlorination processes

Introduction: In 2015, the European Union placed estrogen hormones on the list of compounds with a possible real risk to living organisms and emphasized the need for environmental research. The aim of this study was to determine the occurrence and effect of activated sludge process and chlorination on the fate of 17-beta estradiol and testosterone in hospital wastewater. Materials and Methods: ...
