Blaine McCleskey Carrie A. McDonough Meppelink, Shannon M. Christopher P. Weis Vickie S. Wilson 2021 publication This dataset provides the water-quality results for organic and inorganic concentrations analyzed from samples collected at residential tapwater faucets, sourced from private drinking water wells in Cape Cod, Massachusetts. Samples were collected in July and August, 2018 from 20 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 analyses; and the Organic Chemistry Research Laboratory in Sacramento, California for disinfectant byproduct analyses. Additionally, samples were analyzed for per- and polyfluoroalkyl substances at the Colorado School of Mines in Golden, Colorado. This project seeks to describe differences in tapwater which is sourced from private and public drinking water sources in Cape Cod, Massachusetts. 20180701 20180831 ground condition Complete None planned -70.6970 -69.9170 42.1064 41.4839 World ISO 19115 Topic Category biota None tapwater point of use emerging contaminants USGS Metadata Identifier USGS:5d3f07aae4b01d82ce8d902e World Cape Cod Massachusetts none none None.
