Reconnaissance sampling of 100 streams across the USA to provide baseline data on the occurrence of antibiotics in streams. Occurrences of antibiotics to be compared with predominant animal type for respective watersheds. [C] Reconnaissance sampling to determine occurrence of antibiotics in 30 streams in Iowa and the potential relation of such occurrence to density of swine operations. [C] Cooperative project with CDC Reconnaissance and Experimental Field study of the occurrence of antibiotics, pathogens, and bacterial resistance patterns in soil, surface and ground water at CAFO's [C]. Also occurrence of antibiotics in and near wastewater treatment plants in Georgia [C]. Cooperative Project with EPA occurrence of antibiotics in confined swine feeding operations and in soil, surface and ground water in the Neuse River basin, NC and in surface water and sediment that drains poultry land-use areas in the Delmarva Peninsula [C]. Cooperative project with EPA occurrence of antibiotics in surface water draining areas with confined animal feeding operations in Oklahoma [P]. Assessment of exposure of biota to hormonal simulators (endocrine disruptors) in the field. Conduct laboratory bioassays to determine relative promotion or antagonism of constituents. Relate results to potential species at risk (i.e., low fecundity rates and/or isolated distributions) [P] __________________________________________________________________ Monitoring concentrations and transport of nutrients and bacteria in ground water and soil from swine operations, Savoy experimental field, Fayetteville Arkansas. [C] Monitoring of water quality of springs in karst areas in northern Arkansas populated with poultry AFOs to determine the nonpoint source of nutrient and bacterial contamination. [C] Stateline water-quality monitoring of streams in Arkansas with potential nonpoint contamination from cattle and poultry operations.

[C] RNA ribotyping technique being developed/applied to track the source of microorganisms found in Virginia streams or ground water near AFOs. [C] Use of age-dating techniques and nitrogen isotope ratios on ground-water samples in Colorado to determine if origin of elevated nitrate and ammonia concentrations is from swine operation. Completed study: indicated that nitrogen concen- trations were not related to the current swine operation.[D] Use of dye tracers to determine source of nutrient and bacterial contamination of shallow wells and springs in a watershed with dairy and swine feedlots, Buffalo River watershed, AK. [C] Characterize the distribution and sources of fecal coliform and E.coli in No. Carolina streams and sediments near AFOs (dairies) and use coliphage serotyping techniques to distinguish animal from human fecal bacteria. [C] Development/use of statistical procedures such as discriminant analysis in addition to analyses of isotope and organic tracers to identify the source of nitrate contamination in No. Carolina ground water. Sources being evaluated include poultry waste, swine waste, human waste, and commercial fertilizer. [C] Evaluation of the BARNY and WINHUSLE computer models to compare phosphorus loads from AFOs and croplands in the Otter Creek Watershed, Wisconsin.
