Trap & Treat® BOS 200+® for In Situ MTBE Remediation

Trap & Treat^® BOS 200+^® for In Situ MTBE Remediation

When methyl tert-butyl ether (MTBE) moves farther and faster than the rest of the fuel signature, you need in situ remediation that controls the plume and drives closure. BOS 200+^® delivers long-term MTBE remediation by pairing precise source control with sustained, in‑place biodegradation, giving you an MTBE contamination solution that align with remediation regulations and drives compliance.

Why BOS 200+^® for MTBE and TBA?

BOS 200+^® is purpose‑built for oxygenate plumes. It extends the BOS 200^® platform with a pre‑conditioned activated carbon base plus complex carbohydrates, amino acids, nutrients, and time‑released terminal electron acceptors to support persistent degradation of MTBE and TBA, including where plumes “outrun” hydrocarbons. It performs under aerobic and anaerobic conditions and is insensitive to typical groundwater geochemistry, supporting reliable MTBE remediation in real‑world settings.

Our Proven Approach to

How It Works

The RPI^® Trap & Treat^® BOS 200+^® system leverages nitrate and sulfate as terminal electron acceptors, together with its pre‑conditioned activated carbon matrix, to keep the microbial community active where it matters — in the treatment zone. That design aligns deployment with how oxygenates actually move and degrade in the field, pairing immediate adsorption with sustained in situ biodegradation.

The two core principles of this MTBE contamination solution are simple.

Trap: Activated carbon immediately adsorbs MTBE to cut exposure pathways while the plume is brought under control.
Treat: Pre‑conditioning (complex carbohydrates, amino acids, and nutrients) and time‑released terminal electron acceptors build a robust microbial community to biodegrade oxygenates in place, supporting enhanced MTBE bioremediation and MTBE source control under nitrate‑ and sulfate‑reducing conditions.

Field‑proven results of the success of Trap & Treat^® BOS 200+^® for controlling exposure and treating MTBE contamination include:

MTBE decreases about 50-fold at a gasoline site after a BOS 200+^® injection.
MTBE and TBA were below 10 μg/L within 10 months at another site, setting up long‑term compliance.

Where BOS 200+^® Excels

BOS 200+^® contains no caustic, explosive, or toxic chemicals. The product remains effective across aerobic/anaerobic zones and is tolerant of high salinity, helping teams navigate MTBE remediation regulations and reporting across various subsurface conditions.

BOS 200+^® is a strong fit for the following scenarios:

Gasoline release sites where oxygenates lead the dissolved plume.
Mixed petroleum settings that require simultaneous control of BTEX and oxygenates.
Large projects prioritizing minimal disruption with durable, in‑place outcomes.
