Target-Chemical Concentrations and Microbiological Results for Assessment of Mixed Contaminant and Biological Exposures in Bottled Water, 2020

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.
