May 18, 2020

Data from 38,105 wells were used to characterize fluoride occurrence in untreated United States groundwater. The data were retrieved from the U.S. Geological Survey (USGS) National Water Information System (NWIS). Groundwater samples were collected from 1988 to 2017 in the conterminous United States. Data for groundwater included in this dataset are pH, water temperature, and concentrations of dissolved oxygen, calcium, magnesium, potassium, sodium, alkalinity, chloride, fluoride, silica, sulfate, aluminum, iron, manganese, and total dissolved solids.
