Groundwater nitrate contamination (SSWR.405.1 and SSWR.405.4)

EPA-ORD-CPHEA's Michael Pennino and Jana Compton were invited to present on groundwater nitrate at SSWR’s Quarterly Research Area Coordination Team (RACT) meeting for the Nutrients topic SSWR.4 on June 5,  2024.  This meeting brings together the research coordination team to discuss different products and subproducts within the Nutrients topic.  Their presentation will outline the temporal trends and spatial patterns in nitrate concentrations and risk of nitrate violation across the US landscape, based on a modeling effort to use EPA's National Nutrient Inventory along with other datasets to predict this risk across the conterminous US, published by Pennino et al. in Science of the Total Environment in 2021.  An example testing the accuracy of these predictions using domestic well data in Oregon will be presented and other research on groundwater nitrate contamination in Kansas, along with background information about the National Nutrient Inventory.
