This data release contains the concentration and quality-assurance results for inorganic constituents, as well as organic compounds (volatile organic compounds [VOC], per- and polyfluoroalkyl substances [PFAS], pesticides and disinfection byproducts [DBP]) and microbiological results collected in the Little Big Horn River and residential or commercial tapwater locations in Montana. Twenty-two tapwater samples (six sourced from public supply and 14 sourced from private wells) and six surface-water samples were collected in Montana between August 8-10, 2022. Pharmaceuticals, VOC, and PFAS were analyzed at the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Denver, Colorado. Pesticides and...

This dataset contains the trace element concentration results for samples collected from tapwater sites in East Chicago, Indiana, August-September, 2017, and Chicago, Illinois, July-December, 2017. Samples were collected one time, from 45 private residences and associated drinking water plants and source water locations. Water-quality samples were analyzed at two U.S. Geological Survey laboratories: National Water Quality Laboratory, Denver, Colorado and at the Redox Chemistry Laboratory, Boulder, Colorado.

Water-quality samples were collected at 49 surface water sites covering a range of land uses across the state of Iowa starting the summer of 2022 and continuing into the spring of 2023 by staff from the U.S. Geological Survey Central Midwest Water Science Center. Samples were submitted to the National Water Quality Laboratory in Denver, Colorado, and were analyzed for 32 per- and polyfluoroalkyl substances. Additional samples for N-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD) and 6PPD-Quinone were sent from a subset of the sites to the Organic Geochemistry Research Laboratory in Lawrence, Kansas.

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...

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...
