Target-Chemical Concentration Results of Mixed-Organic/Inorganic Chemical Exposures in Puerto Rico Tapwater, 2017 to 2018

This dataset provides the water-quality results for organic and inorganic concentrations analyzed from samples collected at domestic and commercial tapwater faucets and one spring, sourced in Puerto Rico. Samples were collected in October, 2017 and August and December, 2018 from 19 locations. Samples were analyzed at various U.S. Geological Survey laboratories: the National Water Quality Laboratory in Denver, Colorado for organic compounds; the Redox Chemistry Laboratory in Boulder, Colorado for inorganic constituents; the Organic Geochemistry Laboratory in Lawrence, Kansas for microcystin and pesticides including glyphosate and atrazine; the Organic Chemistry Research Laboratory in Sacramento, California for disinfection byproducts; and at Michigan Microbiological Research Laboratory in Lansing, Michigan for microbiological bacteria cell counts. Additionally, samples were analyzed for per- and polyfluoroalkyl substances at the Colorado School of Mines in Golden, Colorado and for phthalates at the University of Puerto Rico, Mayaguez.
