Improving the Understanding of Nitrate Sources in Freshwater Systems Through Linking Isotopes and Contaminants of Emerging Concern

This publication is designed for water managers, scientists, and environmental practitioners seeking to improve their knowledge of water quality assessment using nitrate isotopes and chemical parameters. It provides expert guidance on the combined use of nitrogen and oxygen isotopes in nitrate together with contaminants of emerging concern to accurately trace pollution sources in freshwater systems. By helping differentiate agricultural, animal-derived and human-derived sources of nitrogen contamination, this publication serves as a valuable resource for the monitoring, management and remediation of water pollution in human-impacted environments.
