A developer wants to build on a brownfield site. A manufacturer needs to demonstrate compliance with a new stormwater permit. A municipality is trying to understand the contamination plume under a closed landfill. Environmental consultants are the technical professionals who get called when organizations face problems that sit at the intersection of engineering, science, regulation, and liability. The work is project-driven, technically demanding, and consequential in ways that are visible in the real world.
What Does an Environmental Consultant Do?
Environmental consultants advise organizations on environmental compliance, site assessment, remediation, permitting, and impact analysis. The role combines field investigation, laboratory data interpretation, technical writing, and client management.
On a given week, an environmental consultant might collect soil and groundwater samples at a contaminated site; review analytical results and compare them to regulatory cleanup standards; develop a remedial action plan for a petroleum-impacted property; prepare an air emissions inventory for a manufacturing client seeking a Title V permit; and present findings to a regulatory agency or client team. They also conduct Phase I and Phase II environmental site assessments, write NEPA environmental impact statements, manage subcontractors on remediation projects, and respond to regulatory agency comment letters.
The work is more writing-intensive than most people expect entering the field. Technical reports, regulatory submissions, and client deliverables are the primary products of environmental consulting practice. Engineers who can write clearly and structure complex technical information for both regulatory and non-technical audiences are consistently more valuable.
Where Do Environmental Consultants Work?
Environmental consulting positions exist at a wide range of firm types across every U.S. state. The career is genuinely national.
Large multidisciplinary engineering and environmental consulting firms including AECOM, Tetra Tech, WSP, Arcadis, and Stantec employ environmental consultants who serve industrial, government, and real estate clients across site assessment, remediation, compliance, and permitting. Mid-size regional environmental consulting firms employ consultants with strong local regulatory knowledge and established client relationships in specific markets. Small specialty consulting firms focus on niche areas including remediation technology, environmental compliance management, or specific regulatory programs.
Federal agencies including the EPA, Army Corps of Engineers, and Department of Defense employ environmental engineers and scientists in regulatory oversight and project management roles. State environmental agencies employ consultants in permitting, compliance, and cleanup program management. Law firms with environmental practices employ technical consultants as expert advisors on environmental litigation. The career is most active in states with significant industrial history, active real estate markets, and strong environmental regulatory programs.
Environmental Consultant Career Trajectory
The ladder runs: Staff Environmental Scientist / Engineer → Environmental Consultant → Senior Consultant / Project Manager → Principal Consultant / Senior Project Manager → Director / Partner.
Staff Environmental Scientist or Engineer is the entry point. You collect field samples, analyze data, draft report sections, and support project managers on client deliverables. Strong attention to detail and the ability to follow established protocols consistently are the baseline requirements.
From there, an Environmental Consultant leads defined project components, manages client communication on specific deliverables, and begins developing independent technical judgment. A Senior Consultant or Project Manager owns full project delivery and client relationships, manages junior staff, and contributes to proposal development. This level typically takes four to eight years to reach.
Principal Consultant and Senior Project Manager roles involve leading multiple projects simultaneously, developing new client relationships, and setting technical standards within a practice area. Director and Partner roles provide full business and technical leadership for a consulting practice.
Environmental Consultant Salary and Job Outlook
The program page references environmental engineers at a BLS median of approximately $97,000 as of 2022. Environmental consultants at large engineering firms track within that range at mid and senior levels. Entry-level staff positions are lower.
| Career Stage | Typical Annual Salary |
|---|---|
| Staff Environmental Scientist / Engineer (entry level) | $48,000 – $66,000 |
| Environmental Consultant (early to mid career) | $64,000 – $88,000 |
| Senior Consultant / Project Manager (mid career) | $84,000 – $115,000 |
| Principal / Director / Partner (senior level) | $110,000 – $170,000+ |
Salaries climb with Professional Engineer (PE) licensure, employer size, geographic location, and specialization. Hazardous materials, PFAS remediation, and environmental compliance management are among the higher-compensating specializations. Major industrial markets including Houston, Chicago, Los Angeles, and the Mid-Atlantic tend to offer stronger base compensation. Large firms pay above regional boutique consultancies at most career stages.
Job Outlook: The BLS projects 6% growth for environmental engineers through 2032. Environmental consulting specifically benefits from expanding PFAS contamination liability, the Infrastructure Investment and Jobs Act’s investment in water infrastructure and remediation, and the ongoing regulatory complexity of environmental compliance across industrial sectors. Consultants with strong technical writing skills alongside engineering credentials are consistently in strong demand.
Skills You’ll Build at Unity
Unity’s BS in Environmental Engineering builds the contamination science, regulatory knowledge, water systems, and technical analysis skills that environmental consulting careers require. The curriculum is directly applicable to the most common project types in the field.
Environmental Remediation and Toxicology (ENGR 304) is the most directly applicable course for site assessment and remediation consulting. It develops the contamination science and toxicological knowledge that environmental consultants apply when evaluating site conditions, interpreting risk, and developing cleanup approaches. Phase I/II site assessment and remediation project work are the bread and butter of environmental consulting practice.
Environmental Fate and Transport (ENGR 402) develops the scientific understanding of how contaminants move through soil, groundwater, and air systems. This knowledge is foundational for developing conceptual site models, designing monitoring programs, and evaluating remediation effectiveness.
Environmental Regulatory Compliance for Engineers (ENGR 310) builds the regulatory literacy that consultants apply across every project type. Understanding the Clean Water Act, Clean Air Act, RCRA, CERCLA, and related state regulations is not background knowledge in environmental consulting; it is the primary framework within which all technical work is conducted.
Environmental Impact Assessment for Engineers (ENGR 313) develops the systematic evaluation skills that environmental consultants apply on NEPA and state equivalent environmental review projects, one of the most active areas of environmental consulting work for infrastructure, energy, and development projects.
Hydrology (ENGR 305) builds the water systems knowledge that underlies much of environmental consulting practice, including groundwater contamination assessment, stormwater management, and watershed-scale environmental analysis.
Data Management in Python (DATA 301) develops the computational data analysis skills that modern environmental consulting increasingly relies on for large dataset management, statistical analysis, and visualization of environmental monitoring results.
How to Get Started
Environmental consulting careers have a well-defined professional development pathway. Understanding it from the start accelerates advancement significantly.
Pursue the Professional Engineer (PE) license as your long-term credential target. The PE is the recognized professional credential for engineers and is expected for senior consulting roles that involve stamping and signing technical documents. The path begins with the Fundamentals of Engineering (FE) exam, which Unity’s program prepares students to take. Note that Unity expects to apply for ABET accreditation in 2029; verify current state FE exam requirements regarding accreditation at the time you plan to sit for the exam.
Consider the Academy of Board Certified Environmental Professionals (ABCEP) Certified Environmental Professional (CEP) credential as a near-term certification target. The CEP is recognized across the environmental consulting field and validates technical competency across environmental science and regulatory disciplines. It is achievable with relevant education and professional experience and is applicable whether your practice focus is site assessment, permitting, or compliance management.
Develop technical writing skills deliberately alongside your engineering education. Environmental consulting firms consistently report that the hardest skill to find in entry-level candidates is the ability to write clear, well-organized technical reports that hold up under regulatory review. Seek out every opportunity to practice technical writing: lab reports, project summaries, case study analyses. The ability to write is what separates competitive candidates in this field.
