11 Jul Works When You Are On Vacation – RPI’s Maintenance-Free Remedies
Over 22 years ago, RPI revolutionized the remediation industry by inventing carbon-based injectates. A key goal was to develop a process requiring no maintenance, starkly contrasting the pump-and-treat and dual-phase extraction systems so prevalent then, as well as ephemeral injectates like oxygenates. These remedies require multiple site mobilizations to support repeated injections or repair of equipment.
We envisioned a remediation process that would operate continuously, year-round, and for years to come. Our solution is to use activated carbon as the foundation for in situ injectates. The activated carbon adsorbs contaminants, and we attack these adsorbed contaminants with a permanent treatment that destroys them. For example, BOS 100® uses metallic iron within the carbon structure to destroy adsorbed chlorinated solvents. BOS 200® and BOS 200+® utilize a supported microbial community to degrade petroleum contaminants. CAT 100 combines both biotic and abiotic modes of destruction. Regardless of the specific product – no maintenance, no fuss remediation proceeds to completion.
With RPI products, you can enjoy peace of mind, knowing that remediation continues at your site—even when you’re on vacation.

Featured Case Study:
Yet Again, BOS 100 Demonstrates PRB Performance Longevity
BOS 100® was injected adjacent to and beneath a stream at a Superfund site using a direct push angle drilling technique to successfully create a PRB and limit PCE flux from the upgradient source area into the stream.
What’s New with RPI Group?
Activated Carbon Injection for In-Situ Remediation
(What is Activated Carbon, Patterns of Distribution upon In Situ Injection, and Evidence of Efficacy)
July 25, 2024 at 2:00PM EST/12:00PM MST
Activated carbon (AC) injection as a remedy for subsurface contamination has gained wide acceptance and is acknowledged for its effectiveness. Hundreds of closure letters, no further action letters, and similar documents have been issued by regulatory agencies in the United States and abroad. This presentation will describe some unique characteristics of activated carbon as a material. We will present patterns of AC distribution upon in situ injection. Finally, will provide evidence of decreasing soil and aquifer concentrations, changes in the microbial population, stable carbon isotopes, confocal microscope, and scanning electron microscope.
