Inorganic Concentration Results for Assessment of Mixed-Organic/Inorganic Chemical and Biological Exposures in North Dakota and South Dakota Tapwater, 2019
tabular digital data
https://doi.org/10.5066/P9DBCKT4
This data set reports results for inorganic constituents analyzed at the Redox Chemistry Laboratory in Boulder, Colorado, for the 2019 tapwater study conducted in North Dakota and South Dakota, USA. This project is part of the U.S. Geological Survey, Environmental Health Mission Area, Water and Wastewater Infrastructure Program.
Data were collected to provide a 'snap shot' into potential human-health exposures from tapwater sources. Samples were obtained from both private groundwater and publicly distributed water sources. Due to privacy concerns, the exact location of samples are anonymized.
