Science-backed remediation technologies built to perform
For over 30 years, we’ve developed the industry’s most trusted in situ remediation technologies — each one field-tested, scientifically validated, and focused on one thing: delivering results that last.
What we offer
Regenesis technologies are engineered to treat a wide range of contaminants — including chlorinated solvents, petroleum hydrocarbons, PFAS, and metals. Our products are designed for enhanced bioremediation, chemical oxidation and reduction, adsorption, and more — all optimized for in situ application.
PFAS Treatment
- Challenge: PFAS resist natural degradation and create groundwater plumes that threaten receptors and communities.
- Treatment need: Requires technologies that capture and immobilize compounds to prevent migration and exposure.
- REGENESIS solutions: PlumeStop and SourceStop bind PFAS in place, removing contaminants from mobile groundwater and reducing risk immediately.
- Applications: Particularly effective for airports, military bases, and industrial facilities where fast, reliable treatment is critical.
Sorption
- Validated approach: Immobilizes dissolved contaminants in groundwater by binding them to solid materials, preventing further migration and reducing exposure risks.
- Advantages: Provides immediate reduction in contaminant concentrations with no energy use, no waste generated, and no need for long-term O&M.
- REGENESIS solutions: PlumeStop uses colloidal activated carbon to coat aquifer materials, capturing PFAS and chlorinated solvents in place while maintaining groundwater flow.
- Applications: Effective for treating PFAS and chlorinated solvent plumes; when paired with electron donor amendments, supports biodegradation and regenerates sorption capacity for extended treatment.
Chemical Oxidation (ISCO)
- Widely applied method: Destroys organic contaminants directly in the subsurface by injecting oxidizing agents into soil and groundwater.
- Targets: Petroleum hydrocarbons, chlorinated solvents, and other persistent organics, breaking them into harmless end products.
- REGENESIS solutions: PersulfOx and RegenOx activate safely in place, sustain reactions over time, and minimize disruption to site operations.
- Applications: Especially effective in source zones or high-concentration areas; delivered via wells, direct-push methods, or soil mixing for rapid, reliable cleanup.
Chemical Reduction (ISCR)
- Remediation approach: Applies strong reductive agents to destroy contaminants directly in the subsurface.
- Targets: Chlorinated solvents, toxic metals such as hexavalent chromium, and other persistent compounds, reducing them to less harmful or immobile forms.
- REGENESIS solution: S-MicroZVI, a sulfidated colloidal zero-valent iron, provides high reactivity, extended longevity, and creates conditions favorable for anaerobic biodegradation.
- Applications: Suited for complex sites; delivered via wells, direct-push methods, or soil mixing for durable, long-term cleanup.
Bioremediation
- Accelerates nature: Modifies aquifer conditions for microorganisms to degrade contaminants into harmless end products.
- Advantages: Low-cost, resilient, and minimally disruptive; effective for petroleum hydrocarbons, chlorinated solvents, and other organics.
- REGENESIS solutions: ORC Advanced delivers controlled-release oxygen for aerobic petroleum degradation; AquiFix and 3-D Microemulsion provide long-term hydrogen release for anaerobic bioremediation of solvents.
- Applications: Suitable for petroleum plumes, chlorinated solvent sites, and mixed contaminant settings; applied via wells or direct-push methods for long-lasting treatment.
Vapor Intrusion Barriers
- Protective systems: Installed beneath buildings to block harmful vapors from migrating into indoor air.
- Targets: Vapors from chlorinated solvents, petroleum hydrocarbons, methane, and other volatile chemicals traveling through contaminated soil or groundwater.
- REGENESIS solutions: TerraShield, MonoShield, Nitra-Seal, and Retro-Coat provide durable, chemical-resistant barriers with advanced materials, validated by rigorous QA/QC testing.
- Applications: Effective for new construction or retrofits; ensures long-term occupant protection while meeting regulatory standards.

Featured Case Study
PFAS Contaminants Reduced to Non-Detect
This case study reviews a bulk storage facility located in the Middle East region that had released a mixed plume of petroleum hydrocarbons and Per and Polyfluoroalkyl substances (PFAS). PFAS constituents were effectively reduced to non-detect following the application of PlumeStop and have remained at these levels for twelve months post-application.

Implementing a PlumeStop Barrier for PFAS Plume Control at Airport in Sweden
At Örnsköldsvik Airport in northeastern Sweden, significant groundwater PFAS contamination had been observed, primarily originating from a fire training ground where PFAS containing Aqueous Film-Forming Foam (AFFF) was discharged during firefighting exercises.

Effective In-Situ Treatment of a 3,280 Ft. PCE Plume in Finland
In Eastern Finland, a fast-moving PCE (perchloroethene) plume beneath a metal-processing facility was remediated to reduce impacts on a municipal drinking water source. The demonstration project achieved PCE concentration reductions of approximately 80% in the plume within months and 90 to 95% by 18 months, ultimately reducing PCE to below the drinking water limit at the municipal water supply well.

SourceStop Reduces PFAS by >99% at Belgian Factory Site
A textile manufacturing facility in Belgium used per- and polyfluoroalkyl substances (PFAS) in its manufacturing process. Over time, spills and leaks led to the accumulation of PFAS in the shallow soil, which eventually leached into the groundwater, forming a diffuse PFAS plume. SourceStop® – Liquid, a colloidal activated carbon (CAC) technology, was applied to reduce PFAS migration beneath the source area.

Successful standalone treatment of a large plume with difficult site conditions
The process of Enhanced Reductive Dechlorination (ERD) for the biological degradation of chlorinated compounds, is now a widely used and proven in situ remediation approach. Nevertheless, ERD is often used only as a ‘polishing step’ of the plume, rather than a stand-alone primary remediation technology.
