What CoreWater Technologies does

CoreWater Technologies is a privately held water treatment technology company founded in 2019 and headquartered in Oberlin, Ohio. The company has developed two proprietary innovations for PFAS ("forever chemicals") remediation: the Core+™ patented composite adsorbent particle—a surface-modified granular activated carbon (GAC) with a functionalized nanoscale coating engineered to selectively adsorb PFAS and enable in-situ regeneration—and the ARID Process™ (Adsorb, Regenerate, Isolate & Destroy), a four-step closed-loop remediation framework that integrates adsorption, in-situ regeneration of media, isolation of PFAS into a salt-free concentrate, and on-site destruction via compatible destruction technologies (EOC, HALT, SCWO, UV photochemical). The technology uses industry-standard GAC as a renewable base, integrates into existing water treatment infrastructure without new equipment, and operates at ambient conditions.

CoreWater serves three customer segments: U.S. water municipalities seeking PFAS removal within existing filter bed operations, commercial and industrial operators seeking to eliminate PFAS emissions, and consumer-facing home water filter manufacturers who embed Core+ into products such as pitchers and under-sink filters. The business model combines technology licensing, Core+ particle sales, and managed on-site treatment arrangements. Distribution occurs through direct enterprise sales to utilities, licensing agreements with GAC producers for broad market reach, and OEM embedding with consumer filter manufacturers. No pricing is publicly disclosed; prospective customers contact the CEO directly for collaboration inquiries.

The company is led by three generations of the Flood family—Dennis M. Flood (President & CEO), Dr. Dennis J. Flood (CTO), and Cody Flood (Director of Research)—with approximately 8 core team members and a board including Dr. George Gray (former EPA Assistant Administrator). To date CoreWater has drawn $2.9 million in private investment at founding and an additional ~$4.9 million in February 2025, for cumulative funding of approximately $7.8 million. The company is actively pursuing joint development agreements and technology licenses, and is positioning its narrative around tightening EPA PFAS drinking water standards as a regulatory tailwind.

Revenue model

1. Technology Licensing: CoreWater Technologies licenses its patented Core+ particle technology and the ARID Process to water utilities, water treatment companies, and GAC manufacturers. The company seeks active joint development agreements and technology licenses as a primary revenue mechanism.
2. Core+ Particle Sales: Sale of the proprietary Core+ composite adsorbent particle to municipal water utilities and commercial/industrial water treatment operators for use in existing filtration infrastructure.
3. Managed Services / On-Site Treatment Systems: CoreWater provides complete on-site PFAS remediation solutions that integrate the ARID Process, potentially offered as managed service arrangements with utilities and industrial facilities.

Core offering

CoreWater Technologies develops and commercializes a proprietary PFAS remediation technology consisting of the patented Core+™ composite adsorbent particle — surface-modified granular activated carbon with a functionalized nanoscale coating that selectively adsorbs PFAS from water and enables in-situ regeneration — and the ARID Process™, a four-step closed-loop framework (Adsorb, Regenerate, Isolate, Destroy) that captures PFAS, strips and reuses the media, concentrates the isolated PFAS into a salt-free stream, and enables permanent destruction.

Product overview

CoreWater Technologies offers a unified water treatment technology portfolio centered on two core offerings: the Core+™ patented composite adsorbent particle (surface-modified granular activated carbon) and the ARID Process™ (a four-step Adsorption, Regeneration, Isolation, and Destruction methodology). These products work together as an integrated system—the Core+™ particle captures PFAS from water, while the ARID Process™ enables in-situ regeneration of the media and on-site destruction of concentrated PFAS. The company serves three distinct market segments: water municipalities (utility-scale filtration systems), commercial and industrial facilities, and consumers (home water filters and pitchers). The technology eliminates hazardous operations associated with PFAS disposal and reduces lifecycle costs compared to traditional single-use granular activated carbon approaches.

• Core+™: Patented adsorbent particle using surface-modified granular activated carbon capable of removing PFAS from water with high efficiency. The material can be rinsed in place and reused for several cycles.
• ARID Process™

Products and services

• Core+™ Composite Adsorbent Particle Patented composite adsorbent particle consisting of surface-modified granular activated carbon engineered to adsorb PFAS from water with high efficiency and to be regenerated and reused in-situ across multiple cycles, extending water treatment bed longevity.
• ARID Process™ (Adsorb, Regenerate, Isolate & Destroy) Four-step PFAS remediation framework integrating Adsorption (Core+ captures PFAS), Regeneration (in-situ chemical rinse releases PFAS and reuses the media), Isolation (PFAS concentrated into a salt-free controllable waste stream), and Destruction (concentrated PFAS destroyed on-site using compatible destruction technologies such as EOC, HALT, SCWO, and UV photochemical systems).
• CoreWater Municipal Water Systems Water treatment solution for U.S. water municipalities using filter beds for primary filtration, integrating Core+ and the ARID Process to enable PFAS removal, in-situ regeneration, and on-site destruction while reducing landfill waste and lifecycle costs versus conventional granular activated carbon systems.
• CoreWater Commercial & Industrial Solutions Water treatment technology for commercial and industrial users seeking to produce PFAS-free drinking water and eliminate PFAS emissions from their operations, delivered via Core+ and the ARID Process.
• CoreWater Consumer Products (via Home Filter Manufacturers) Channel for home water filter manufacturers to embed CoreWater's patented Core+ particle into consumer products such as water pitchers and under-sink filters, enabling PFAS-free drinking water for households and supporting filter recycling programs that reduce landfill contamination.
