The first phase of corporate PFAS strategy — installing removal technology such as GAC or ion-exchange to meet drinking-water MCLs and discharge obligations — is largely behind most affected companies. It does not, however, solve the underlying liability question, because removal only concentrates the problem into a spent medium. The second phase, focused on destruction of those concentrated streams via electrochemical oxidation, plasma or supercritical water oxidation, is now the defining corporate PFAS decision for 2026–2028, and it demands a different sensor, data and governance architecture. Boards should treat it as a process technology change on that scale, not as a procurement line item.

Why Removal Alone Is No Longer Sufficient
Between 2022 and 2025, most large industrial and utility PFAS programmes focused on removal. Granular activated carbon, ion-exchange resin and reverse osmosis were the dominant technology choices, and the operational focus was on the 4 ppt MCL for PFOA and PFOS in drinking water and on early implementation of state-level industrial discharge limits.
That focus was appropriate for its time. What has changed since is not a single rule but a tightening of the waste end of the problem:
- Federal treatment of PFAS waste is still unsettled. EPA’s February 2024 proposal to list nine PFAS — including PFOA, PFOS and GenX — as RCRA hazardous constituents is still pending, not final; in May 2026 the agency withdrew a separate RCRA corrective-action definition rule, and its Spring 2025 regulatory agenda continues to list the PFAS listing as an intended finalisation. The direction of travel is clear even where the rule is not.
- Landfill and incinerator acceptance has tightened. Several major operators now decline spent GAC and resin without documentation of PFAS-specific handling, and incineration of PFAS media has been shown in independent studies to release short-chain PFAS byproducts — an environmental and reputational problem of its own.
- EPA issued updated interim guidance on the destruction and disposal of PFAS in April 2026, which steers waste managers toward Class I wells, RCRA landfills and thermal treatment while acknowledging significant data gaps. It is guidance for comment, not binding standards, but it signals how regulators will read disposal choices.
The consequence is a strategic dead end: companies that installed removal technology now accumulate PFAS-laden media that is hard to dispose of, carrying an environmental and balance-sheet liability that grows with every regeneration cycle.
The Destruction Alternative
Destruction technologies convert PFAS into fluoride and short-chain organic acids, eliminating the media disposal problem. The three with meaningful commercial traction in 2026 are:
- Electrochemical oxidation (EO): mature, scalable, well suited to concentrated PFAS streams from foam fractionation.
- Plasma treatment: energy-intensive but effective on gaseous PFAS byproducts.
- Supercritical water oxidation (SCWO): highest capital cost, strong destruction efficiency across a wide range of PFAS compounds.
Each works on concentrated streams rather than dilute inflows, so they sit downstream of a concentration step such as foam fractionation. Every destruction reactor is also a demanding sensor environment: aggressive oxidants, elevated temperatures, fluoride byproducts and dynamic process behaviour.
Shanghai ChiMay’s inline analyzer family has been engineered around those conditions, with materials specifications and firmware capabilities that support continuous operation in destruction reactor environments.
Board-Level Framing for the Second Phase
Six questions frame the decision:
- Scale and pace: how much of the corporate PFAS stream should be routed to destruction, and over what horizon?
- Technology selection: EO, plasma, SCWO, or a combination, based on stream composition and volume?
- In-house versus service model: build and operate destruction reactors internally, or contract a service provider?
- Sensor and data architecture: what monitoring package supports both technical performance and regulatory defensibility?
- Regulatory alignment: how do we work with EPA and state agencies to have the chosen destruction pathway recognised within the compliance framework?
- Stakeholder communications: how do we explain the transition to shareholders, employees, the community and customers?
Each question has technical, financial and reputational dimensions. Boards that work through all six explicitly tend to move through the transition with materially fewer surprises than boards that debate only the technology choice.
Investment Profile
A representative investment profile for a mid-size industrial site making the removal-to-destruction transition, to be read as a planning shape rather than a quotation:
| Category | 2026 | 2027 | 2028 |
|---|---|---|---|
| Foam fractionation upgrade | USD 2 M | USD 1 M | USD 500 K |
| Destruction reactor CAPEX | USD 4 M | USD 8 M | USD 6 M |
| Sensor and monitoring package | USD 600 K | USD 400 K | USD 200 K |
| Regulatory engagement | USD 300 K | USD 200 K | USD 150 K |
| Training and organisational | USD 250 K | USD 200 K | USD 150 K |
That totals about USD 24 million over three years for a mid-size site. Larger sites can face several times that figure over the same period. Boards should size the investment relative to the enterprise value at risk, which is usually far larger than the destruction investment itself.
Sensor Architecture as a Strategic Enabler
The sensor architecture is a strategic input, not just an operational component, for three reasons:
- Regulator engagement: destruction technologies are new, and regulators want monitoring evidence before they accept a pathway. A well-designed architecture shortens that conversation.
- Insurance underwriting: environmental carriers now differentiate destruction pilots by the sensor data available, and stronger monitoring improves the terms available.
- Litigation defence: sensor data from destruction reactors is a primary evidence source in any future PFAS litigation.
Shanghai ChiMay’s coordinated package for destruction reactors — inline pH, conductivity, ORP, dissolved oxygen and turbidity on a shared transmitter platform — provides that data foundation without a multi-vendor integration.
Governance Considerations
The board should establish governance protocols for the destruction programme early. Standard elements:
- Quarterly board review of programme milestones and sensor data quality.
- Annual third-party audit of the destruction reactor monitoring system.
- Named executive accountability for the destruction programme, separate from routine sensor deployment.
- Regular briefings to major shareholders on progress and material risks.
These protocols support the programme itself and they strengthen the governance narrative that ratings agencies and investors evaluate.
Communicating the Transition
The transition is significant enough to warrant deliberate stakeholder communication:
- A public commitment to destruction as the corporate PFAS strategy, aligned with sustainability reporting cycles.
- Technical white papers or case studies documenting programme performance.
- Regular engagement with community and environmental groups.
- Investor day content covering the strategic rationale and expected financial impact.
Companies that communicate the transition well tend to receive more favourable ESG scoring and stronger stakeholder support than companies that treat it as a private operational matter.
Timeline Considerations
For a company starting the transition in 2026, a realistic sequence:
- 2026 Q3: strategic decision and initial capital commitment.
- 2026 Q4: pilot destruction reactor procurement and installation.
- 2027 H1: pilot operation and regulator engagement.
- 2027 H2: scale-up decision and full-system procurement.
- 2028: full destruction system operation, with monitoring data building the compliance evidence base.
Companies that follow this sequence should have destruction capability in place before the next wave of PFAS tightening, which most observers expect in the 2028 timeframe.
Closing Thoughts
The removal-to-destruction transition is the defining corporate PFAS decision for the 2026–2028 window. Boards that frame it as a strategic decision rather than a technology substitution, invest in the sensor and data architecture that makes destruction defensible, and communicate the programme with intent will enter the next regulatory phase with materially less risk than boards that stay with removal alone. Shanghai ChiMay’s analyzer platform, designed for both conventional water quality monitoring and destruction reactor conditions, is one of the more defensible technical foundations available for that transition.
