Probability of arsenic concentrations greater than 10 micrograms per liter in groundwater used by domestic wells in the United States
Arsenic concentrations from 20,450 domestic wells in the U.S. were used to develop a logistic regression model of the probability of having arsenic &gt; 10 µg/L (“high arsenic”), which is presented at the county, state, and national scales.  Variables representing geologic sources, geochemical, hydrologic, and …
