PlumeStop is an innovative groundwater remediation technology that rapidly reduces contaminant concentrations and accelerates biodegradation in situ. Unlike traditional granular activated carbon, PlumeStop is a colloidal suspension that can be widely dispersed throughout the subsurface using simple injection methods, overcoming distribution challenges and reducing application costs. Its dual function—rapid sorption of contaminants and creation of a high-surface-area matrix for microbial colonization—results in immediate risk reduction and long-term contaminant destruction.

Highlights:

• Wide-Area Dispersion: PlumeStop’s colloidal formulation allows for easy and uniform distribution throughout soil and groundwater using low-pressure injections, overcoming the limitations of traditional activated carbon and reducing the number of required injection points, which lowers costs and site disturbance.
• Rapid Contaminant Reduction: The technology quickly sorbs contaminants from groundwater, achieving dramatic concentration reductions (often >90–99%) within days to weeks after application.
• Enhanced Bioremediation: PlumeStop provides a favorable matrix for microbial colonization, concentrating contaminants and degraders together, which accelerates biodegradation rates and enables effective treatment even at very low contaminant levels.
• Long-Term, Sustainable Solution: The reagent is not consumed during remediation, allowing for ongoing immobilization and biodegradation of contaminants over decades, making it ideal for addressing persistent sources and matrix back-diffusion.
