Broad incumbents

• Tetra Tech: Global consulting and engineering firm with a large EHS and environmental remediation practice. Comparable because it delivers site assessment, remediation, EHS compliance, and water/environmental services to the same regulated verticals HETI serves, though at vastly greater scale.
• AECOM: Mega-cap engineering and environmental services firm with substantial EHS, remediation, and compliance auditing practices. Comparable in service lines and verticals served; differs primarily in scale and capital structure.
• Jacobs Solutions: Global professional services firm with a significant environmental and EHS practice including site investigation, remediation, and industrial hygiene. Overlaps with HETI's environmental and EHS service lines but at significantly larger scale.
• WSP Global: Global engineering consultancy with environmental, EHS, and site assessment practices. Comparable in EHS compliance and remediation delivery and in the regulated-vertical client base, though it serves a far broader geographic and service footprint.
• Arcadis: Global design and consultancy firm with established environmental and EHS advisory services. Comparable for environmental due diligence, remediation, and EHS compliance work targeting real estate, financial services, and industrial clients.

Direct peers

• Environmental Resources Management (ERM): Largest pure-play global EHS and sustainability consultancy. Directly comparable as it provides site investigation, EHS auditing, industrial hygiene, and sustainability risk services to insurance, energy, life sciences, and healthcare clients—the same mix that anchors HETI's book of business.
• SLR Consulting: Global environmental and advisory consultancy with deep site assessment, remediation, and EHS capabilities. Closely comparable as it competes for the same regulated-environmental mandates and serves overlapping insurance, energy, and real estate client segments.
• Trinity Consultants: Specialist EHS consulting firm focused on air quality, permitting, and regulatory compliance. Directly comparable on environmental compliance, air pollution control, and EHS auditing services that map closely to HETI's multimedia compliance audit work.
• Haley & Aldrich: Northeast-based environmental and geotechnical consulting firm. Comparable as it serves similar real estate, industrial, and institutional clients on site assessment, remediation, and EHS compliance with a similar specialty-firm profile.
• Roux Associates: Mid-sized environmental consulting firm specializing in site investigation and remediation under state-specific Licensed Site Professional programs. Closely comparable in service mix and in the state-licensed professional model that defines HETI's competitive moat.
