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,...
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...

This data set contains the result for inorganic constituents and organic compounds collected from tapwater locations, as well as water filtration plants, in East Chicago, Indiana, and Chicago, Illinois in 2017. Additionally quality assurance data collected was summarized. Residential samples collected were done so directly from residential kitchen taps (faucets) as is, it was noted if a point-of-use filtration device was utilized by the homeowner, but they were not removed for sampling. Samples were collected at various times of the day, without regard to previous water use. Results were analyzed using ToxCast, and Exposure Activity Ratios (EARs) are presented. Water filtration plant samples were taken from Lake...
