Battelle 2026 - Accelerating Reductive Dechlorination Using In Situ Alcoholysis of Electron Donor	This poster evaluates a catalyzed electron donor system based on in situ alcoholysis of vegetable oils to enhance reductive bioremediation. Field results demonstrate improved donor distribution, increased volatile fatty acid production, rapid establishment of reducing conditions, and accelerated degradation of chlorinated solvents in source zones.

Battelle 2026 - Identifying Preferential Flow Paths Using iFLUX Samplers: Quantifying Groundwater and Contaminant Flux at Discrete Depths	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.

Battelle 2026 – Enhancing Biodegradation in Clay-Rich Soils Using ISCO and Reinjectable DPT Points	This poster evaluates a combined ISCO and anaerobic biostimulation approach for BTEX remediation in clay-rich soils. Reinjectable direct-push injection points enable repeated amendment delivery, while CSIA and monitoring data confirm the transition from chemical oxidation to sustained anaerobic biodegradation, improving treatment performance in low-permeability environments.

Battelle 2026 – Rethinking Remediation: Using CSIA to Strengthen Site Decisions	This poster highlights the use of compound-specific isotope analysis (CSIA) to improve interpretation of remediation performance. By distinguishing degradation from dilution and identifying dominant pathways, CSIA strengthens conceptual site models and supports more confident, defensible site decisions.	View Download
