FRx

What FRx does

FRx, Inc. is a privately held specialty industrial services company founded in 1994 by Larry Murdoch and Bill Slack — both formerly adjunct faculty at the University of Cincinnati, where they led US EPA-funded research on applying hydraulic fracturing to environmental remediation. The firm is operationally headquartered in Travelers Rest, South Carolina, and delivers in situ injection services for the cleanup of contaminated soil, bedrock, and groundwater. Over its 30-year history FRx has executed thousands of injection events at more than 350 sites spanning 42+ US states, Ontario, Quebec, and Northern Europe, working in geological media ranging from soft shallow soils and glacial till to deep crystalline bedrock at depths from approximately 3 ft to 225 ft.

The company's core technology is the patented DPT Jet Injection Method (US Patent 6102621) and associated slurry transport formulation, which enables controlled sheet-like hydraulic fractures to deliver oxidants (potassium permanganate, sodium persulfate, Fenton's Reagent), reductants (zero valent iron, emulsified ZVI), bioremediation amendments, and proppants into target formations. FRx monetizes this capability through three principal application services: Well Enhancement (delivering up to ten-fold greater discharge rates than conventional wells), Contaminant Capture via Passive Reactive Barriers, and Diffusive Distribution (passive reagent delivery producing treatment halos that persist for up to a decade). A 2023-era innovation initiative called C-SURGE adapts the same injection approach to shallow geologic carbon storage and flood-risk mitigation through sawdust injection.

FRx operates exclusively as a project-based professional services provider — it sells no products, performs no drilling itself, and custom-mobilizes its own equipment and trained crews to each client job site. Pricing is fully project-specific (quotation issued after the firm reviews site characterization data on elevations, geology, contaminant profile, and remedial approach), with multi-year contract cadences and the option to deliver turn-key engagements in which FRx purchases remedial materials and oversees the full scope. The firm is tightly held by its founders with no disclosed institutional investors, no parent company, fewer than 50 employees, and named senior personnel including President Larry Murdoch (concurrently Clemson University Professor of Geology), Treasurer Bill Slack, VP of Operations Doug Knight, Director of Technology Chapman Ross, and Senior Geologist Drew Baird (joined 2015).

Core offering

FRx provides specialty injection and delivery services for in situ remediation of contaminated soil, bedrock, and groundwater. The company uses proprietary hydraulic fracturing methods—most notably the patented DPT Jet Injection technique—to place treatment materials at targeted subsurface elevations, enabling removal or in situ destruction of contaminants. Services are delivered by dispatching custom-built equipment and trained crews to client sites, and can be executed in turn-key fashion including procurement of remedial materials.

Product overview

FRx is a specialty injection services company offering a unified portfolio of in situ remediation solutions centered on proprietary hydraulic fracturing technology. The core offering is the DPT Jet Injection Technology, which creates controlled fracture structures for delivering treatment materials into contaminated subsurface formations. This core technology enables three primary application services: Well Enhancement (improving flow rates to/from wells), Contaminant Capture via Passive Reactive Barriers, and Diffusive Distribution for passive long-term reagent delivery. FRx also offers an innovation initiative called C-SURGE applying the same injection technology to shallow geologic carbon storage for climate mitigation. The company works with various treatment materials (oxidants, reductants, bioremediation amendments, proppants) that are injected through the hydraulic fracture structures. All services are delivered through custom-built equipment packages deployed to client sites across North America and Northern Europe.

• US EPAcoreStrategic or Co-development Partner · 1 January 1986US EPA funded research projects at University of Cincinnati off-campus laboratory led by founders Larry Murdoch and Bill Slack. EPA funding supported development and validation of hydraulic fracturing technique for environmental remediation, including bench-scale demonstrations, field tests at clean test sites, and first contaminated site application in Oak Brook, Illinois (1990). FRx was founded in 1994 to provide services related to these EPA-developed technologies.

Broad incumbents

• WSP: Global professional services firm with a sizable environment and remediation practice, including legacy Golder Associates expertise in geotechnical and environmental services. Comparable to FRx in the contamination cleanup space though with a much broader service mix and global footprint.
• Clean Harbors: Large environmental and industrial services provider offering site remediation, waste management, and emergency response across North America. Overlaps with FRx on contaminated-site work but at vastly larger scale, broader service portfolio, and as a potential prime contractor that may subcontract specialty injection.
• Tetra Tech: Global consulting and engineering firm with a deep environmental remediation practice spanning site assessment, design, and field implementation. Comparable to FRx in environmental services but operates at much greater scale across water, environment, and sustainable infrastructure.
• AECOM: Major global infrastructure consulting firm with substantial environmental services practice including site investigation and remediation. Comparable as a buyer of specialty injection services or as a competitor on integrated remediation programs, though AECOM operates at vastly broader scope.
• Stantec: Global engineering, architecture, and environmental services firm with North American environmental remediation capability. Comparable in serving contaminated-site customers and providing injection-based in situ treatment design, but at much larger scale and broader portfolio.
• Arcadis: International design and consultancy firm with a meaningful environment and remediation practice, including legacy Callidus and Hyder Consulting capabilities. Comparable as a remediation services competitor or partner, but Arcadis operates across many sectors at enterprise scale.
• ERM (Environmental Resources Management): Global sustainability and environmental consultancy with deep practice in contaminated site management and remediation strategy. Comparable in advising and supporting remediation projects involving subsurface injection, though ERM operates as a broad consultancy rather than specialty injection provider.

Direct peers

• Haley & Aldrich: Geotechnical and environmental engineering firm offering subsurface characterization and remediation services. Comparable to FRx as a specialty consultancy working on contaminated site remediation with deep technical expertise and direct involvement in injection and in situ treatment programs.
• Geosyntec Consultants: Environmental and geotechnical engineering consultancy with strong practice in in situ remediation, soil and groundwater treatment, and emerging contaminant work. Directly comparable to FRx in technical depth on injection-based delivery of treatment reagents into low-permeability formations.
• Cascade Environmental: Provides drilling, injection, and direct-push services for environmental remediation projects. Comparable to FRx in the field-deployment model for delivering materials into subsurface formations and in the customer base of remediation site owners and engineering consultants.
