Target-chemical concentrations and microbiological results in surface water and tapwater, Montana, 2022 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...

Of these samples 252 were from publicly supplied tapwater locations, and 155 were sourced from private wells, springs or catchment vessels. Additionally, three surface-water samples were collected in New Hampshire (as denoted with a site code suffix of '_SW' in Table 2a). An additional 85 samples were collected at 3 locations (privately sourced tapwater samples in New Jersey (30) and South Carolina (20), and a publicly...

Mead, Nebraska, is an agricultural community about 30 miles west of Omaha. To help address the lack of data on broad contaminant exposures in TW sourced from private water wells, a total of 22 samples were collected from 18 private wells during June 2022 and January 2023 and analyzed for 495 organic compounds, 34 inorganic constituents, and 11 microbial groups. The organic compounds included pesticides, pharmaceuticals, volatile organic compounds (VOCs), disinfection byproducts...

Samples were obtained from multiple publicly distributed water sources in Minnesota in 2019. Due to privacy concerns, the exact location where samples were collected are not reported and station identification numbers have been anonymized.
