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 Laboratory.

In the United States and globally, the lack of data on contaminant exposure from unregulated private-well point-of-use (POU) tapwater (TW) is a recognized public health data gap and an obstacle to risk management and homeowner decision making. Mead, Nebraska, is an agricultural community about 30 miles west of Omaha. To help address the lack of data on broad contaminant exposures in TW sourced from private water wells, a total of 22 samples were collected from 18 private wells during June 2022 and January 2023 and analyzed for 495 organic compounds, 34 inorganic constituents, and 11 microbial groups. The organic compounds included pesticides, pharmaceuticals, volatile organic compounds (VOCs), disinfection byproducts (DBPs), per- and polyfluoroalkyl substances (PFAS), and cyanotoxins. An additional three samples from existing private POU water filters were collected and analyzed only for pesticides. Pesticides and disinfection byproducts (DBP) were analyzed at the USGS Organic Chemistry Research Laboratory (OCRL) in Sacramento, California. Pharmaceuticals, VOCs, and PFAS were analyzed at the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Denver, Colorado. Cyanotoxins were analyzed at the USGS Organic Geochemistry Research Laboratory (OGRL) in Lawrence, Kansas. Inorganic constituents were analyzed at the USGS Redox Chemistry Laboratory (RCL) in Boulder, Colorado. Microbiological samples were analyzed by the USGS Michigan Bacterial Research Laboratory (MIBaRL) in Lansing, Michigan.

In the United States and globally, contaminant exposure in unregulated private-well point-of-use (POU) tapwater (TW) is a recognized public health data gap and an obstacle to both risk management and homeowner decision making. To help address the lack of data on broad contaminant exposures in private-well TW from hydrologically vulnerable (alluvial or karst) aquifers in agriculturally intensive landscapes, samples were collected in 2018-2019 from 47 northeast Iowa farms and analyzed for 437 unique organic compounds, 32 inorganic constituents, 5 in vitro bioassays, and 11 microbial assays.

Chemical and biological concentration results, quality assurance and quality control and statistical summaries from 26 tapwater samples, collected from paired residential and work place sites in 11 states in 2016. Samples were analylzed at U.S. Geological Survey and U.S. Environmental Protection Agency laboratories.

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 and recorded in the National Water Information System (NWIS) (Table S2). Stream discharge (ft3/s) and gage height (ft) values were estimated using available rating curves from adjacent USGS stream gages when available and relative flow was categorized by comparing discharge on the day of sample collection to discharge over the previous three to five years. Samples were analyzed at U.S. Geological Survey laboratories: bacteria enumeration and growth and antibiotic resistance genes at the Michigan Bacteriological Research Laboratory and antibiotic concentrations at the Organic Geochemistry Research Laboratory.
