You've successfully filtered PFAS and other challenging contaminants out of your water, protecting public health and ensuring compliance. Now, you’re left with thousands of pounds of saturated "Spent Carbon" or ion exchange resin. The moment that media is vacuumed out of the vessel, it enters a critical regulatory pipeline.
Under the Resource Conservation and Recovery Act (RCRA) and stringent new state-specific PFAS regulations, the site owner is designated as the Generator of that waste. This means your responsibility for that material is "cradle-to-grave" – from its creation until its final destruction or secure sequestration. Navigating this labyrinth of compliance requires more than just a disposal contract; it demands an ironclad audit trail.
A Hazardous Waste Manifest is a specialized, multi-part shipping document (most commonly EPA Form 8700-22) that serves as a legal tracking system for hazardous waste. It accompanies the waste from the generator's site, to the transporter, and finally to the designated treatment, storage, and disposal facility (TSDF).
For spent carbon or resin media, the manifest must precisely detail the waste codes, physical state, total weight, and the concentration of chemical constituents like PFAS to ensure proper handling and compliance with federal and state environmental laws.
Understanding each phase of the waste lifecycle is crucial for maintaining compliance and minimizing liability:
This is the point when the media is declared "spent" and removed from the filtration vessel. Analytical testing of the spent media is performed to determine its specific hazardous waste codes (eg D004 for arsenic, D008 for lead, or specific state codes for PFAS). This analytical data creates the Waste Profile Number, which is essential for proper manifesting.
Selecting only EPA-licensed hazardous waste transporters is non-negotiable. The manifest must travel with the waste at all times, acting as its legal passport. Any discrepancies between the manifest and the load can lead to severe penalties.
This is the final, authorized destination. For spent carbon, this might be high-temperature incineration (for PFAS destruction) or thermal reactivation (where the carbon is treated and potentially reused, though often not for PFAS-laden media due to cross-contamination risks).
The most critical step in closing the loop is receiving the signed-back copy of the manifest from the TSDF. This document confirms that the waste was received and managed as intended. Without it, your "cradle-to-grave" responsibility remains open-ended.
Ensuring compliance with PFAS waste manifesting hinges on document synchronization and timeliness. Operators must meticulously verify that the Waste Profile Number on the manifest precisely matches the laboratory analytical data for the spent media.
Furthermore, the generator is legally required to receive a signed, dated confirmation of disposal from the TSDF within 35 to 45 days of the waste leaving their site. Failure to receive this confirmation within the specified window mandates the filing of an Exception Report to the EPA, indicating a potential break in the chain of custody.
The traditional paper manifest system is a hotbed for compliance failures:
A robust digital system is no longer a luxury; it’s a necessity for real-time tracking and automated compliance alerts.
Managing the lifecycle of spent media requires more than just a disposal contract; it demands a defensible record of action. Want to see FieldEx in action? Book a free demo today, or simply reach out. We're here to help.
