Product Overview
ABC-Olé® is an emulsified fatty acid ester substrate engineered to support anaerobic bioremediation of chlorinated solvents and related contaminants in soil and groundwater. Designed as a high-performance alternative to traditional emulsified vegetable oils (EVO), ABC-Olé provides a balanced blend of long-lasting carbon, buffering agents, and fast-acting components to establish and sustain strong reducing conditions.
With excellent mobility and stability in the subsurface, ABC-Olé is well-suited for sites where maintaining an effective, long-term electron donor source is critical for complete reductive dechlorination.
Features & Benefits
Optimized Fatty Acid Ester Blend
Contains 30–55% fatty acid esters, providing a reliable and durable carbon source for sustained microbial activity.
Formulated for High-Permeability Aquifers
Engineered to remain effective even in areas with higher groundwater flow, ensuring persistent availability of electron donor.
Balanced Chemistry for Predictable Performance
Includes buffering and fast-acting components to quickly establish favorable conditions for anaerobic microbes.
Supports Complete Reductive Dechlorination
Promotes the biological breakdown of chlorinated ethenes and other compounds all the way to non-toxic end products.
Improved Stability and Distribution
The emulsified structure enhances subsurface migration, ensuring consistent contact with contaminated zones.
How It Works
ABC-Olé® delivers an emulsified carbon substrate into the subsurface, where it slowly breaks down and releases hydrogen—the electron donor required for microbial reductive dechlorination. This process supports naturally occurring bacteria capable of sequentially transforming chlorinated solvents through their complete degradation pathway.
The formulation helps maintain stable anaerobic conditions over extended periods, giving microbial communities the environment they need for efficient and reliable contaminant reduction.
Applications
ABC-Olé® is effective for anaerobic bioremediation of:
- Chlorinated solvents
- PCE, TCE, DCE, VC
- Chlorinated ethanes
- Chlorinated methanes
- Pesticides
- Industrial solvents
- Other contaminants treated via reductive pathways
Suitable for treating both source zones and dissolved-phase groundwater plumes.
Delivery & Handling
ABC-Olé® is provided as a pumpable liquid emulsion that can be injected through:
- Direct-push points
- Injection wells
- Recirculation systems
Its flowable formulation makes it straightforward to handle in the field, and its natural, biodegradable ingredients make it safe and environmentally responsible.
