In Situ Bioremediation

When hydrocarbons impact the subsurface, your first priority is to control exposure while treating contamination. RPI®‘s Trap & Treat® technologies enable in situ bioremediation by pairing adsorption with sustained biostimulation — contaminants are adsorbed to activated carbon while a supported microbial community degrades them in place. The result is practical cleanup of gasoline, diesel, lube oils, and fuel oxygenates that keeps working underground without ongoing maintenance.

How Trap & Treat® Supports in Situ Bioremediation

Trap & Treat® applies a carbon‑plus‑biology platform to treat petroleum impacts in place. 

The core elements are:

  • Adsorption for exposure control: An activated carbon platform adsorbs dissolved hydrocarbons in soil and groundwater, cutting off risk pathways while treatment proceeds.
  • Sustained biostimulation: Select nutrients and time‑released terminal electron acceptors support a vigorous microbial community capable of degrading petroleum hydrocarbons across aerobic and anaerobic zones.
  • Technologies that fit the site: BOS 200® addresses petroleum hydrocarbons in dissolved plumes and LNAPL, while BOS 200+® extends the platform with enhanced nutrition for complex mixtures, to address extensive LNAPLs, heavy hydrocarbons, and oxygenates such as MTBE and TBA.

Where RPI®‘s Technology Excels 

Trap & Treat® supports soil bioremediation techniques at petroleum‑impacted sites where adsorption for exposure control and biology for long‑term mass reduction are needed. 

Common use cases include:

  • Bioremediation of oil spills in the subsurface, including weathered hydrocarbons under variable redox conditions
  • Gasoline and diesel plumes near source areas and along downgradient migration pathways
  • LNAPL management, where a carbon platform plus biostimulation can drive sustained degradation and move sites toward closure

One-Stop Design, Installation, and Verification 

Effective in situ bioremediation with RPI® starts with Remedial Design Characterization (RDC) to map mass and pathways. These data inform targeted designs that place treatment where it will be most effective. Turnkey installations are performed solely by RPI®‑approved installers, who deliver the carbon‑based slurry efficiently throughout the subsurface. Our in-house RPI® Support Lab provides GC/MS and selected inorganic analyses at no charge before, during, and after projects to help confirm distribution and track performance over time. 

How RPI® Integrates in Situ Bioremediation

Trap & Treat® brings RPI®‘s in situ bioremediation approach to your site design. Using advanced quantitative high-resolution site characterization (qHRSC) and remedial design characterization (RDC) to understand contamination patterns and support a superior conceptual site model (CSM), we develop targeted strategies and treatment procedures that include built‑in biostimulation to sustain degradation across changing subsurface conditions. 

If your team is evaluating bioremediation companies, Trap & Treat® technologies integrate seamlessly with your program. The activated carbon platform controls exposure while an aerobic/anaerobic microcosm drives ongoing biological degradation — supporting efficient, data‑driven site management. Your team retains full control of the remediation strategy while RPI® provides proven technologies, design input informed by RDC data, and Support Lab analytics to help verify distribution and track progress.

Why Choose RPI®‘s Carbon‑Plus‑Biology Approach?

RPI’s Trap & Treat® platform is engineered for real‑world variability. It combines activated carbon adsorption for exposure control with in‑place biological or abiotic treatment that keeps working underground.

It provides:

  • Exposure control and treatment in one step: Adsorption interrupts risk pathways while microbes degrade hydrocarbons in place.
  • Suitability for changing conditions: The microcosm functions in both aerobic and anaerobic subsurface conditions.
  • Life cycle support: From RDC through installation and post‑treatment checks, the emphasis is on site‑specific design and measurable outcomes.
