Input and results from a random forest classification (RFC) model that predicts redox conditions in groundwater in the contiguous United States This data release provides model inputs and outputs for a model that predicts redox conditions in groundwater in the contiguous United States. Input variables describe the hydrology, soils, geology, and hydrologic position of groundwater sample locations. The data release accompanies a journal article that describes model development and applications (Tesoriero_and_others_2023).

The database provides information for each withdrawal point including estimated location and completion interval (Moreo and others, 2003). Groundwater withdrawal estimates for each withdrawal point have been compiled by water use and year. Uncertainty was assigned to the annual withdrawal values based on the use and method of estimation (Moreo and others, 2003)....

A base model was constructed using water-level, salinity, and withdrawal data available during the period from 2009 to 2017. Groundwater recharge for the base model was from a published daily water budget representing rainfall for the period 1984-2008. The SUTRA code was modified to include simplified unsaturated zone properties in the subroutine UNSAT. Changes in...
