SOURCES, TEMPORAL VARIATIONS, AND FATE AND TRANSPORT OF SELECTED ENDOCRINE DISRUPTING COMPOUNDS AND PHARMACEUTICALS, NEBRASKA, USA. Presented at National Ground Water Association's Third International Conference on Pharmaceuticals & Endocrine Disrupting Chemicals in Water, Minneapolis, MN, 3/19-21/2003.
Description:
Known or suspected endocrine disrupting compounds have been detected in water from streams, groundwater, and drinking water. In 2001 and 2002, the U.S. Geological Survey in cooperation with the U.S./ Environmental Protection Agency and the City of Lincoln, Nebraska, collected various environmental water samples from the City of Lincoln well field and nearby surface waters to evaluate (1) the sources (samples were collected from a lagoon at two animal feeding operations and from the effluent of a wastewater treatment plant) and temporal variations of known or suspected endocrine disrupters, pharmaceuticals, hormones, and othere wastewater compounds and (2) the fate and transport of these compounds from the Platte River through an alluvial aquifer into water from wells used for drinking water. Environmental samples were analyzed for more than 150 dissolved compounds, including herbicides and their metabolites; personal-care products; prescription and nonprescription drugs; and industrial compounds. In addition, batch and undisturbed column experiments are being done (1) to determine differences in transport and attenuation of selected contaminants in riverbed sediments with different hydrologic conditions and (2) to assess attenuation processes. Samples of batch and column experiments will be analyzed for atrazine, alachlor, alachlor ethylsulfonic acid, sulfmethoxazole, sulfathiazole, trymethoprin, lyncomycin, erythromycine, chlortetracycline, and 17-p-estradiol.
