In Situ TPH Remediation

The Challenge of TPH Contamination

Benzene is not the only regulatory trigger that can stall operations, depress property values, and invite costly penalties — total petroleum hydrocarbons (TPHs) drive the completion of risk pathways. RPI®‘s in situ BOS 200+® eliminates TPH in the subsurface, restoring sites to safe, compliant conditions without digging, hauling, or long-term equipment maintenance.

TPH contamination often results from accidental spills or improper disposal of fuels, oils, and petroleum products used in transportation, refining, and manufacturing industries. Left unchecked, each compound contributes to contamination in both soil and groundwater, making TPH a risk to human health and the environment. 

TPH contamination can also lead to: 

  • Regulatory compliance violations.
  • Long-term environmental damage.
  • Delays in property transactions or redevelopment.

Our Noninvasive In Situ TPH Remediation Solution

Our science-backed technology and field-demonstrated BOS 200+® deliver cost-effective TPH cleanup right where contamination sits. Our products are safe for people, infrastructure, and the environment.

RPI®‘s proprietary approach combines: 

  • Activated carbon: These platforms instantly capture and immobilize contaminants. 
  • Microbial blends: They break down hydrocarbons under aerobic and anaerobic conditions.
  • Nutrient blends: These formulations sustain microbial biodegradation for long-term TPH remediation solutions.

How It Works

How Our In Situ TPH Remediation Services Work

RPI group companies provide processes that deliver fast, lasting results for even the most challenging sites:

  • Assessment and modeling: We begin with high-density conceptual site modeling to pinpoint contamination and determine the most effective treatment design. 
  • Immediate contaminant capture: Activated carbon adsorbs TPH, cutting off exposure pathways and stabilizing the site. 
  • Accelerated biodegradation: Proprietary microbes, supported by time-released nutrients and electron acceptors, break down petroleum hydrocarbons. 
  • Long-term protection: Treatment remains active in the subsurface, preventing contaminant rebound and delivering sustained TPH remediation.
