Vegetative buffer strips have been demonstrated to effectively reduce loads of sediment, nutrients, and herbicides in surface runoff, but their effectiveness for reducing veterinary antibiotic loads in runoff has not been well documented. Surface runoff simulation where performed to determine the effectiveness of Vegetative buffer strips vegetation and width on surface runoff loads of the veterinary antibiotics sulfamethazine and lincomycin. The three datasets in this release document 1. physical and chemical soil properties for soil located on experimental vegetated buffer strip plots prior to surface runoff simulations; 2. Rainfall simulator performance data and antecedent soil water content data for all vegetated...

Chemical and microbiological results, quality assurance and quality control, site location, and method information for surface water, bed sediment, and wastewater effluent collected from 34 stream locations across Iowa (United States). Environmental samples were analyzed for a suite of 29 antibiotics, plated on selective media for 15 types of bacteria growth, and DNA was extracted from culture growth and used in downstream polymerase chain reaction (PCR) assays for the detection of 24 antibiotic resistance genes. Environmental field data were collected in-situ for water temperature (°C), specific conductivity (µs/cm), dissolved oxygen (mg/L), pH (standard units), and turbidity (FNU) using a multiparameter sonde...

Chemical and biological results, quality assurance and quality control, and method information from groundwater, surface water, and litter samples, collected from nine locations in Iowa and one in Wisconsin in 2016. Thirteen groundwater, nine surface water, four poultry litter, and four QA/QC samples were collected. Samples were analyzed at U.S. Geological Survey laboratories; bacteria, pathogens, and antibiotic resistance genes at the Michigan Bacteriological Research Laboratory, F+ specific coliphage at the St. Petersburg Coastal and Marine Science Center, hormones and antibiotics at the Organic Geochemistry Research Laboratory, nutrients at the National Water Quality Laboratory, total estrogenicity at Fish Health...
