Description

This presentation demonstrates how iFLUX samplers quantify groundwater and contaminant mass flux at discrete depths to identify preferential flow paths that control plume migration. By integrating flux measurements with compound-specific isotope analysis (CSIA), the IsoFLUX approach distinguishes degradation from dilution and provides a more defensible basis for site characterization and remediation decisions.  Authors:  David F.
