文摘

Available tools to trace the origin of pollutants at industrial sites are inadequate. Data of stable isotopes of H2O in groundwater at an industrial site are shown. High ClO3 and ClO4 contents and 2H enrichment are found in groundwater. The electrolysis process leads to a large 2H enrichment (+ 425‰) in solutions. Isotopes enable to identify pollutants released from storage tanks or soil.
