This technical reference illustrates the abiotic and biotic degradation pathways for chlorinated volatile organic compounds (CVOCs), linking contaminant fate and transport to applicable in situ remediation and bioremediation technologies.

Learn how BioBoost™ GeoChem enhances CVOC remediation by improving iron mobility, promoting reactive iron sulfide formation, and supporting sustained sulfate-reducing conditions. This poster discusses the science behind coupled abiotic and biological degradation pathways and key considerations for field implementation.

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.

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.   

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.

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.

SDS for Tersus Environmental’s BioBoost™ GeoChem amendment used to generate reactive iron sulfide (FeS) minerals in situ.

This document summarizes Tersus Environmental’s remediation technologies for chlorinated volatile organic compounds (CVOCs), including chlorinated ethenes and ethanes. The brochure covers abiotic and biotic treatment pathways, in situ chemical reduction, enhanced bioremediation, and integrated approaches for source areas, dissolved plumes, and leading-edge conditions.

Compound-Specific Isotope Analysis (CSIA) is a powerful environmental forensics and performance-monitoring tool used to evaluate contaminant sources, distinguish degradation mechanisms, and assess the effectiveness of remediation treatments. This Tech Brief explains how CSIA supports plume forensics, monitored natural attenuation (MNA), and verification of remediation performance at petroleum and chlorinated solvent sites.
