A proprietary injectable amendment designed to treat petroleum hydrocarbons in groundwater and soil through sorption and biodegradation.
How It Works
BOS 200® is a high-performance, carbon-based amendment specifically designed to treat petroleum hydrocarbons in groundwater and soil. It utilizes a proprietary blend of activated carbon and support compounds to rapidly capture and immobilize contaminants.
Mechanism:
- Sorption: High-surface-area carbon adsorbs hydrocarbons on contact, significantly reducing dissolved-phase mass.
- Biodegradation Support: BOS 200® includes a proprietary nutrient blend that stimulates native microbial populations, accelerating aerobic biodegradation of adsorbed and dissolved contaminants.
- Sustained Remediation: Combines immediate mass reduction with long-term biological activity for continued performance after injection.
BOS 200® is highly effective even in coarse-grained soils and can be injected into smear zones, residual LNAPL areas, and groundwater plumes.
Performance Results
BOS 200® has achieved >90% reduction in petroleum mass at numerous impacted sites.
- Gasoline Plume Collapse: 93% BTEX reduction in 4 months – Urban fuel station, Northeast U.S.
- TPH Reduction: >80% DRO reduction – Military motor pool, Southwest U.S.
- LNAPL Smear Zone Cleanup: Confirmed disappearance of mobile LNAPL with no rebound after 2 years – Coastal remediation site
Common applications:
- BTEX, LNAPL, and TPH plumes
- Residual smear zones
- Fuel depot or UST releases
- MNA supplement or post-excavation polishing
Typical site types:
- Gas stations
- Refineries and terminals
- Rail yards and logistics hubs
- Military fueling areas
- Airports
- Emergency spill response sites
