Direct peers

• Clean Harbors: Largest publicly traded North American provider of environmental and industrial services, including hazardous waste management and site remediation. Directly comparable to RSI across excavation, treatment, and disposal services, though at vastly greater scale and geographic breadth.
• SCS Engineers: Environmental engineering and construction firm delivering remediation, landfill design, and compliance services. Overlaps with RSI on landfill expansion, lagoon closures, and site remediation projects.
• Heritage Environmental Services: Privately held hazardous waste management and environmental services firm offering treatment, disposal, and on-site remediation. Closely matches RSI's hazardous waste, lagoon closure, and industrial decontamination capabilities.
• Cascade Environmental Holdings: National environmental services firm providing soil and groundwater remediation, drilling, and demolition services. Comparable to RSI in service mix, federal/industrial client focus, and mid-market positioning.
• Sevenson Environmental Services: Specialty contractor focused on environmental remediation, including soil and groundwater cleanup, sediment remediation, and demolition. Direct mid-size competitor to RSI with overlapping federal and industrial client base.

Broad incumbents

• Veolia North America: Global environmental services operator offering hazardous waste treatment, soil remediation, and industrial cleanup. Competitor to RSI on large industrial decontamination and remediation projects, with substantially greater geographic and capital footprint.
• Clean Earth: National provider of specialized waste management and environmental services, including hazardous waste treatment and contaminated soil handling. A broader incumbent with overlapping disposal and treatment capabilities but a wider portfolio.
• Stericycle: Large regulated waste services provider focused on medical and hazardous waste. Overlaps with RSI on hazardous waste handling and compliance, but Stericycle's scale and regulated-waste focus make it a broader incumbent rather than direct competitor.
• Tetra Tech: Global consulting and engineering firm with a large environmental services practice covering site assessment, remediation design, and water treatment. Competes with RSI on engineering-led remediation programs, though its model is primarily consulting rather than self-perform contracting.

Emerging players

• Brownfield Restoration Group: Specialty contractor focused on brownfield site remediation and redevelopment support, overlapping with RSI's State Voluntary Clean-Up Programs and brownfield redevelopment workstreams.
