Product Overview
RemSorb® is a patented, ready-to-use colloidal activated carbon suspension designed for rapid, in situ adsorption of organic contaminants in groundwater. Engineered for outstanding mobility and permanent deposition in the subsurface, RemSorb creates highly effective adsorption barriers that stop contaminant migration and support long-term site stability.
Developed for robust performance even in challenging conditions, RemSorb is ideal for both source zone treatment and plume management, providing fast concentration reductions and long-lasting protection.

Features & Benefits
Immediate Plume Cutoff
Quickly adsorbs organic contaminants, reducing concentrations within weeks and preventing further migration. Effective on dissolved and sorbed contaminants.
High Controlled Subsurface Mobility
The colloidal formulation is optimized to move easily through the aquifer matrix during injection, ensuring uniform distribution in the target zone. Within a few days, RemSorb adheres to the soil matrix, preventing the risk of carbon being washed out.
Safe and Environmentally Compatible
Produced with extremely high-quality activated carbons approved for use around drinking water resources.
Long-Term Effectiveness
Once deposited, the fine activated carbon particles remain in place, creating an in situ barrier that can last for many years with no maintenance.
Supports Natural Attenuation
By retaining contaminants on its surface, RemSorb creates conditions that promote microbial degradation over time. Amendments can be added to support microbial activity.
Ideal for Sensitive or Low-Impact Sites
Provides rapid and reliable results without excavation, pumping systems, or significant site disruption.
How It Works
RemSorb® is ideal for the in situ treatment of:
- Petroleum hydrocarbons (TPH)
- Aromatics (BTEX, etc.)
- PAHs
- MTBE and ETBE
- Chlorinated and halogenated organic contaminants
- Pesticides
- Persistent Organic Pollutants (POPs)
- Almost any organic contaminant
- A wide range of dissolved-phase organic pollutants
Common deployment scenarios include:
- Permeable reactive barriers (PRBs)
- Plume cutoff walls
- Source zone stabilization
- Low-impact remediation at active industrial or commercial properties
