What Insitu Remediation Services Ltd does

InSitu Remediation Services Limited (IRSL) is a privately held Canadian environmental remediation company headquartered in St. George, Ontario, with staging sites in Calgary, Ottawa Valley, and Vancouver. The company delivers in-situ and ex-situ treatment of contaminated soil and groundwater, targeting petroleum hydrocarbons, chlorinated solvents, PFAS compounds, and LNAPL across bulk fuel facilities, gasoline retail stations, industrial sites, and residential properties. IRSL has operated for 15 years and reports 200+ worksites completed across 17 countries in North America, Central America, South America, Europe, and the Middle East, and self-describes as one of Canada's largest remediation companies.

IRSL's service portfolio is organized into three layers: in-situ treatment (chemical oxidation, chemical reduction, aerobic and anaerobic bioremediation, cosolvent flushing, surfactant flushing, and hybrid remediation); ex-situ treatment (activated carbon, groundwater treatment, NAPL removal, soil vapour treatment, thermal treatment, and integrated remediation); and remediation support services (performance modeling, remedial option reviews, system audits, system optimization, and tracer testing). The company deploys proprietary tooling, including an analytical model for injection design and several specialized extraction configurations (pneumatic skimming, dual-phase extraction, and multiphase extraction), and operates a technology partnership with Regenesis for PlumeStop and Colloidal Activated Carbon deployments. Portable, pre-packaged equipment is a deliberate design choice to support projects in permafrost, desert, and other remote locations.

IRSL generates revenue through project-based professional services contracts with facility owners, environmental consultants, and industrial clients. Pricing is quote-based and project-specific with no public disclosure. The go-to-market motion is sales-led and direct, supplemented by referrals from environmental consulting firms, industry conference presence, published case studies, and active membership in eight professional associations. The company has a Brazilian operating brand, Aquífero Serviços de Remediação, and a Mandarin Chinese-language website, signaling formal expansion into Latin America and tentative interest in Asia. No funding rounds, M&A activity, headcount, or revenue figures are publicly disclosed.

Core offering

Insitu Remediation Services Ltd provides in-situ and ex-situ environmental remediation services for soil and groundwater contamination, including chemical oxidation/reduction, aerobic and anaerobic bioremediation, cosolvent and surfactant flushing, activated carbon treatment, NAPL removal, and thermal and soil vapour treatment. The company also offers remediation support services such as performance modeling, remedial option reviews, system audits and optimization, and tracer testing, and specializes in deploying portable equipment to remote and challenging environments.

Product overview

Insitu Remediation Services Ltd offers a comprehensive portfolio of environmental remediation services organized into three main categories: In-Situ Remediation (chemical oxidation, chemical reduction, aerobic bioremediation, anaerobic bioremediation, cosolvent flushing, surfactant flushing, and hybrid remediation systems), Ex-Situ Remediation (activated carbon treatment, groundwater treatment, NAPL removal, soil vapour treatment, thermal treatment, and integrated remediation), and Remediation Support services (performance modeling, remedial option reviews, remedial system audits, remedial system optimization, and tracer testing). The company also provides specialized remote location remediation services for challenging environments. The portfolio is structured as a service-based offering rather than a software platform, with each remediation technology available as a distinct service offering tailored to specific contamination types including petroleum hydrocarbons, chlorinated compounds, PFAS, and heavy metals.

Products and services

• Chemical Oxidation An in-situ remediation technique that injects oxidizing agents into contaminated soil and groundwater to break down organic pollutants, used by industrial and commercial clients with petroleum hydrocarbon or chlorinated compound contamination.
• Chemical Reduction An in-situ remediation technique that uses reducing agents to transform contaminants such as chlorinated compounds into less harmful substances in soil and groundwater.
• Aerobic Bioremediation Uses oxygen and naturally occurring microorganisms to biodegrade organic contaminants in soil and groundwater, applied at petroleum hydrocarbon and other organic-contaminated sites.
• Anaerobic Bioremediation Uses anaerobic microorganisms to break down contaminants in the absence of oxygen, typically applied at chlorinated solvent sites.
• Cosolvent Flushing Injecting cosolvents to enhance the solubility and mobility of hydrophobic contaminants for removal from soil and groundwater.
• Surfactant Flushing Uses surfactants to reduce surface tension and mobilize contaminants for extraction from soil at sites with NAPL or other hard-to-treat contamination.
• Hybrid Remediation Combines multiple in-situ remediation technologies to address complex contamination scenarios that cannot be resolved with a single technique.
• Activated Carbon Treatment Uses activated carbon adsorption to remove organic contaminants from extracted water and soil at industrial and commercial sites.
• Groundwater Treatment Treatment systems designed to treat contaminated groundwater that has been extracted from contaminated sites.
• NAPL Removal Removal of Non-Aqueous Phase Liquids such as oil and gasoline from groundwater and soil at bulk fuel, retail, and industrial sites.
• Soil Vapour Treatment Treatment systems for soil vapors extracted from contaminated sites to remove volatile organic compounds.
• Thermal Treatment Uses thermal energy to volatilize and remove contaminants from soil at sites with heavy or recalcitrant contamination.
• Integrated Remediation Combines multiple ex-situ treatment technologies for comprehensive site remediation of complex contamination scenarios.
• Performance Modeling Predictive modeling services to simulate and optimize remediation system performance, used by clients and consultants during project design and review.
• Remedial Option Reviews Technical evaluation of various remediation approaches for a specific site, helping clients select the most appropriate technology.
• Remedial System Audits Independent assessment of existing remediation systems for compliance and effectiveness, delivered to facility owners and regulators.
• Remedial System Optimization Services to improve the efficiency and cost-effectiveness of existing remediation systems, delivered to owners of operating treatment systems.
• Tracer Testing Testing using tracers to understand groundwater flow patterns and contaminant migration at remediation sites.
• Remote Location Ready Remediation Services Remediation services specifically designed for remote and challenging environments including permafrost, mountains, and deserts, deploying portable equipment and minimal-infrastructure setups for industrial clients.
