Soil and Groundwater Remediation

For over 20 years, our products have been used to successfully treat soil and groundwater at thousands of polluted sites around the world. We respond to the nature of soil and groundwater with our products, remediation and bioremediation technologies and individually developed remediation concepts for contaminant removal. This is because each site requires the selection of the right remediation measures. 

Our portfolio of proven chemical oxidation, chemical reduction, metals treatment and bioremediation technologies promotes the rapid and cost-effective removal of a wide range of organic compounds and heavy metals that have a harmful impact on soil and groundwater. We continue to develop and offer several effective remediation technologies including ISCO, ISCR, bioremediation, metals treatment and stabilization. Learn more about our diverse portfolio of proven remediation technologies.

Chemical Oxidation

The KLOZUR® persulfate portfolio comprises multiple high-value, environmental-grade persulfate products used for In-Situ Chemical Oxidation (ISCO) of contaminants in soil and groundwater including petroleum hydrocarbons, chlorinated solvents, and PAHs.

Chemical Reduction

EHC® ISCR reagent consists of controlled-release carbon, zero-valent iron (ZVI) particles, and nutrients used for in situ treatment of groundwater and saturated soils contaminated with heavy metals and persistent organic compounds such as chlorinated solvents, pesticides, and energy sources.

EHC® Liquid ISCR Reagent is a liquid version of EHC® ISCR Reagent and is specifically designed for injection through existing wells or hydraulic injection networks to treat a wide range of groundwater contaminants.

EHC® Plus is a combination of EHC reagent and powdered activated carbon (PAC). This combined approach can be used to treat groundwater and saturated soil contaminated by persistent halogenated compounds, including chlorinated solvents, pesticides, and organic explosives.

DARAMEND® treats soils containing chlorinated herbicides and pesticides, organic explosives and chlorinated VOCs (CVOCs), often eliminating the need for excavation. 

Enhanced Reductive Dechlorination

ELS® is a lecithin-based, food-grade carbon substrate used to enhance anaerobic bioremediation and is delivered as either a 25 percent microemulsion or a 100 percent concentrate that is cold-water soluble. 

Aerobic Bioremediation

TERRAMEND® Reagent aerobic bioremediation reagent is a cost-effective technology for treating soils contaminated by organic compounds. TERRAMEND® technology can often be used without excavation, does not produce odors or leachate, and does not cause soil bloat.

PERMEOX® Ultra is a specially formulated calcium peroxide that provides prolonged oxygen release for enhanced aerobic bioremediation. PERMEOX® Ultra contains a minimum of 18% active oxygen and is available in powder and granule form.


GEROFORM® Biogeochemical Reagents provide the building blocks needed to promote biogeochemical reactions in situ. GEOFORM® provides a source of sulfate, iron, electron donors, pH buffers and nutrients to promote mechanisms for dehalogenation through enhanced anaerobic bioremediation, abiotic degradation and the formation of reactive minerals.

Metals Treatment

METAFIX® Reagents are custom formulations of reducing agents, reactive minerals, mineral activators, catalysts and pH modifiers for cost-effective treatment of heavy metals at even the most challenging sites. 

NAPL Stabilization/Mass Flux Reduction

ISGS® remediation technology uses a permanganate-based solution to geochemically stabilize dense non-aqueous phase liquids (DNAPL) in the aquifer.

Portfolio of Proven Technologies

ISCO, ISCR, bioremediation and metal stabilization technolgies are used to treat contaminated soil.

We offer ISCO, ISCR, metal stabilization and bioremediation technologies based on proven science and decades of results. We treat a wide range of contaminants. Our persulfates are suitable for a variety of application methods, including fixed wells, direct push, pneumatic and hydraulic fracturing, soil mixing and more.

Laboratory Services and Equipment Rentals

The modern equipment of our environmental laboratory allows us to conduct research, field tests and special studies on soil and groundwater contamination.

In a state-of-the-art environmental laboratory, we focus on research and development and studies for soil and groundwater treatment. We have quantitative field test kits specifically designed for soil and groundwater applications, as well as the equipment and expertise to mix and process products.

Experienced technical support

We provide our customers technical support in chemistry, microbiology, geology and field applications and evaluate their data.

A team of experienced environmental professionals, including PEs, Ph.D. scientists, and recognized experts in chemistry, microbiology, geology, and field applications, will estimate your product needs and assist you with planning and remediation activities, including on-site. Based on the application, we will evaluate your data at no charge.
