GAC Reactivation

We offer an alternative reactivation solution designed for systems that generate smaller quantities of granular activated carbon (GAC).  Our process enables isolated, small-batch reactivation of GAC, making reactivation feasible and cost-effective for smaller systems through our exclusive partnership with DESOTEC.

Additionally, we provide traditional media exchange services and stock management where we store your reactivated media until the next scheduled changeout, allowing for greater operational flexibility and streamlined inventory management. This approach helps utilities optimize media usage while reducing waste and overall treatment costs.

Responsible Disposal

Whether your utility prefers incineration or landfill disposal, Sentinel delivers a turnkey media disposal solution, handling logistics from media removal and packaging to transport, documentation, and facility coordination. We ensure that disposal is conducted safely, legally, and with full transparency.

Landfill Disposal Coordination

For utilities seeking a non-thermal disposal route, we facilitate permitted landfill disposal of spent GAC and IX resin in accordance with applicable local, state, and federal regulations. This includes:

• Waste characterization and profiling
• Coordination with RCRA-compliant landfill facilities
• Transportation logistics and documentation
• Support with disposal approvals and permitting

High-Temperature Incineration

Where appropriate, Sentinel coordinates the secure thermal destruction of spent media via permitted incinerators, a preferred option for PFAS-impacted materials. Our incineration support includes:

• Management of PFAS-laden GAC or IX resins
• Chain-of-custody and transport compliance
• Partnering with EPA-approved thermal treatment facilities
• Detailed reporting for audit and compliance needs
