NRSA2324 Nitrate Stable Isotope Ratios

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2025-06-02
Stable Isotope Ratios of Nitrate from the National Aquatic Resource Survey 2023 and 2024. We analyzed 163 samples with nitrate concentrations above 2 mg-N/L for oxygen and nitrogen isotopes of nitrate. We also include the water stable isotope values for those same samples. Metadata and QA data are provided in the spreadsheet.
