Comparative Analysis of PFAS Removal Methods: H2Plus Technology Efficacy Study

Introduction

The widespread contamination of water sources by per- and polyfluoroalkyl substances (PFAS) has catalyzed a global effort to mitigate health and environmental risks posed by these persistent compounds. As regulatory limits tighten—most notably under new EPA maximum contaminant levels—utilities, industries, and remediation firms are urgently seeking the most effective, cost-efficient, and scalable treatment options available.

This white paper presents a comparative evaluation of conventional PFAS removal technologies versus the H2Plus hydrated electron-based destruction system, with a focus on destruction efficiency, operational cost, environmental impact, and deployment flexibility. The findings are based on field data, laboratory testing, and independent third-party validation.

Software and tools

H2Plus provides utilities and organizations with:

Comparative ROI analysis vs. GAC/RO systems
Custom pilot units for site-specific validation
Third-party lab support for defensible results
Full system integration with SCADA and water operations
Regulatory support packages for EPA/state compliance reporting

Overview of Common PFAS Treatment Methods

Technology	Mechanism	Removal Efficiency	Waste Byproduct	Notes
Granular Activated Carbon (GAC)	Adsorption	High for long-chain PFAS	Requires regeneration/disposal	Poor short-chain removal
Ion Exchange Resins	Adsorption	High for many PFAS types	Requires disposal/regeneration	Selectivity issues
Reverse Osmosis (RO)	Filtration	Very high	High-energy use and brine waste	Expensive and not scalable for large volumes
Foam Fractionation	Surface tension separation	Effective for some PFAS	Concentrated foam waste	Limited field applications
Thermal Incineration	High-temp destruction	Complete	High cost, energy, and emissions	Questionable reliability in practice
H2Plus Technology	Hydrated electron degradation	Up to 99%+ (incl. short-chain)	No secondary waste	Cost-effective, scalable destruction

Performance Metrics from H2Plus Pilot Studies

PFOA Reduction: From 1,885 ng/L to 2.9 ng/L (99.8%)
PFOS Reduction: From 1,215 ng/L to 37 ng/L (97%)
Cost per gallon treated: ~$0.09 (compared to $0.24–$0.45 for alternatives)
System Footprint: Modular and mobile (fits in shipping container or skid)

Lifecycle & Environmental Impact

Unlike filter- or capture-based systems, H2Plus permanently breaks PFAS molecules into safe byproducts like water, CO₂, and fluoride salts. There is no need for incineration, landfill disposal, or brine management—dramatically reducing downstream liabilities and environmental costs.

Conclusion

In the evolving landscape of PFAS remediation, not all treatment technologies are created equal. While legacy methods like GAC and RO serve as temporary containment strategies, they do not solve the core problem—and often create new ones.

H2Plus offers a fundamental shift: a scalable, field-proven method that actually destroys PFAS. With significantly lower operating costs, no hazardous waste streams, and high destruction efficacy across PFAS chemistries, H2Plus represents a best-in-class solution for long-term compliance and environmental stewardship.
