Soil and groundwater remediation

Daramend® Reagent

DARAMEND® Reagent represents a superior treatment technology for solid materials impacted by recalcitrant organic compounds. Since the first application in 1996, variations of the technology have been successfully used to treat >10,000,000 tons of soil, sediment and other solid materials.

DARAMEND® Reagent treats soils containing chlorinated herbicides and pesticides, organic explosive compounds, and chlorinated VOCs (CVOCs) at many sites throughout the world. The DARAMEND® technology is uniquely advantageous because it can often be applied without excavation; its implementation generates no odors or leachate; and it is typically applied at 1 to 3% (soil mass), so it does not result in soil bulking.


  • Improves soil health - tilth and fertility - reduces toxicity
  • Hydrophilic character increases soil water holding
  • Balanced range of nutrients
  • Promotes remediation of most persistent contaminants in soils


  • Organic explosives
  • Chlorinated VOCs
  • Chlorinated pesticides

Key functions

  • In situ landfarming
  • Shallow groundwater trench applications


In situ chemical reduction (ISCR) is the combination of abiotic chemical reduction, using zero valent iron(ZVI) and/or reduced minerals (magnetite, pyrite), coupled with anaerobic bioremediation for the effective treatment of chlorinated solvents, pesticides, and energetics. Physical, chemical, and biological processes combine to create an extremely reduced environment that stimulates chemical and microbiological dechlorination of otherwise persistent compounds.

Technical bulletins

This document summarizes our experience treating organochlorine pesticides (OCPs) in soil and groundwater using DARAMEND® and EHC® Reagents.

DARAMEND® application guides

We present common soil and groundwater remediation approaches for the use of DARAMEND® Reagent as a cost-effective solution for excavation backfills and trench-type PRB applications.

DARAMEND® webinars

Dr. Alan Seech explains how DARAMEND® Reagent controls soil chemistry to foster chemical and microbiological processes that enhance the anaerobic destruction of key explosive compounds and their degradation products.

Dr. Alan Seech presents the original in situ chemical reduction technology based on DARAMEND® Reagent. Case studies show the advantages of this effective and cost-efficient technique compared to other soil remediation methods.

Dr. Alan Seech provides an overview of the chemistry of the ISCR process for treating pesticides using a cyclic, anaerobic/aerobic approach. A key advantage of this ISCR treatment is its ability to meet even the most stringent residential soil remediation criteria.

Dr. Alan Seech will provide an overview of Evonik's reagents for in situ and ex situ remediation of soils contaminated with organic explosives and organic compounds. He will present the benefits, composition, treatment chemistry and applicability for remediating soil contamination of the DARAMEND® family, and share results from completed projects where DARAMEND® has been used to effectively remediate soils.
