This data release contains concentration and quality-assurance results for inorganic, organic analytes and microbiological pathogens collected from 30 different commercial bottled water sources. Samples were processed on July 20 and August 17, 2020 at the New Jersey Water Science Center and analyzed at various U.S. Geological Survey laboratories. Samples were analyzed for nutrients, cations and anions, trace elements and rare earth elements (REE) at the Redox Chemistry Laboratory and Analytical Trace Element Chemistry Laboratory in Boulder, Colorado; pharmaceutical, pesticide, per- and polyfluoroalkyl substances and volatile organic compounds at the National Water Quality Laboratory, Denver, Colorado; disinfection byproducts at the Organic Chemistry Research Laboratory, Sacramento, California; and microbiology at the Environmental and Public Health Microbiology Laboratory, St. Petersburg, Florida and Michigan Bacteriological Research Laboratory, Lansing, Michigan.

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 DBP were analyzed at the USGS Organic Chemistry Research Laboratory (OCRL) in Sacramento, California. Inorganic contaminants were analyzed at the USGS Redox Chemistry Laboratory (RCL) and the Analytical Trace Element Chemistry Laboratory (ATECL), Boulder, Colorado. Cyanotoxins were analyzed at the USGS Organic Geochemistry Research Laboratory (OGRL), Lawrence, Kansas. Microbiological pathogens were analyzed by the National Institute of Health/National Institute of Allergy and Infections Disease, Rocky Mountain Laboratory, Hamilton, Montana.
