Summary

This data release contains chemical and isotopic data used in an investigation of nitrate sources and transport in the Upper Illinois River basin. Samples (total = 445) include river water from the Upper Illinois River and its major tributaries plus urban wastewater and agricultural groundwater. Data include concentrations of nitrate, chloride, and sulfate; isotope ratios of N and O in nitrate; and isotope ratios of H and O in water.

Purpose

Data were collected as part of an investigation of seasonal and spatial variation of nitrate sources and transport processes in the Upper Illinois River Basin to inform management practices aimed at reducing nitrogen loads to the Mississippi River and nutrient-sensitive coastal waters in the Gulf of Mexico.
