NO3GWT version 1.0.0

A groundwater Nitrate Decision Support Tool (GW-NDST) for wells in Wisconsin was developed to assist resource managers with assessing how legacy and possible future nitrate leaching rates, combined with groundwater lag times and potential denitrification, influence nitrate concentrations in wells (Juckem et al. 2024). The GW-NDST was reviewed and approved by the journal via this official USGS approved and released version 1.0.0 of the software. Updates were made to the code following submission of the paper to the journal and prior to publication of the paper. Thus, this version 1.0.0 of the software is expected to be superseded at the time of publication of the paper.
