What are the steps to get licensed as an environmental engineer?

Earning a degree in environmental engineering is the first step toward a career in the field, but a license is required for higher responsibility and independent work. Here’s what it takes to become a licensed environmental engineer in the US.

1. Pass the Fundamentals of Engineering (FE) Exam: The FE exam is administered by the National Council of Examiners for Engineering and Surveying (NCEES). Passing it is the first major step toward professional licensure.

The test evaluates one’s knowledge in areas like math, ethics, fluid mechanics, and environmental chemistry. This computer-based, six-hour exam includes 110 questions on general engineering and environmental topics.

2. Gain Relevant Work Experience: Accumulate at least four years of qualifying engineering experience under the supervision of a licensed Professional Engineer (PE). Hands-on training in areas like site remediation, air quality control, and wastewater management helps prepare professionals for independent work.

Similar to how aspiring professionals explore how to become a park ranger—which involves formal education, fieldwork, and sometimes state-specific requirements—future environmental engineers must meet specific criteria to advance in their careers.

3. Pass the Principles and Practice of Engineering (PE) Exam: Candidates become eligible for the PE exam in environmental engineering after completing four years of supervised work experience. The PE exam is a nine-hour, open-book exam with 80 questions, covering both theoretical knowledge and real-world problem-solving. Administered by the NCEES, the exam requires a deep understanding of engineering ethics, sustainability principles, and risk management.

4. Obtain State Licensure: To legally practice as a Professional Engineer (PE), candidates must apply for licensure through their state's engineering board. After obtaining licensure, they will be recognized as PEs in environmental engineering. This designation allows them to sign off on projects, take on leadership roles, and offer engineering services independently.

What degree do you need to become an environmental engineer?

To pursue a career as an environmental engineer in the US, a bachelor's degree in environmental engineering is the standard educational requirement. Alternatively, an online engineering degree in related fields such as civil, chemical, or general engineering is also acceptable. 

For those planning to obtain licensure, enrolling in a standard degree track or dual degree programs accredited by the Accreditation Board for Engineering and Technology (ABET) is highly recommended. Many states require this accreditation for professional certification, as it ensures a strong educational foundation. For engineers looking to advance further, a master’s degree can provide specialized expertise and lead to higher-level roles in the field.

How do recent graduates stand out in the environmental engineering job market?

Landing a job in environmental engineering takes more than just having a standard or accelerated college degree. Employers want to see real-world experience and specialized skills. Taking the initiative to build these early on can make graduates more competitive in the job market.

• Gain Practical Experience: Participating in internships or cooperative education programs allows students to develop industry-specific skills and build stronger resumes.
• Develop Specialized Skills: Gaining expertise in areas such as renewable energy, sustainable design, or environmental compliance can increase employability. To develop these, students can take elective courses or complete a specialized training program like an
• Obtain Professional Certifications: Earning credentials like the Engineer-in-Training (EIT) or Leadership in Energy and Environmental Design (LEED) accreditation showcases a commitment to the field. Candidates can prepare for these certifications through coursework, self-study, or training programs offered by professional organizations. There are also easy certifications to get online that can enhance skills and boost employability.

How can students gain hands-on experience in environmental engineering?

Internships are one of the best ways to apply theoretical knowledge in real-world settings. The US Environmental Protection Agency (EPA) offers programs like the Green Engineering Internship, while job platforms like Indeed provide listings for opportunities across the country. Many universities and no application fee online colleges also facilitate internships, such as the University of Washington’s Department of Civil & Environmental Engineering. 

Volunteer work is another great option. Organizations like Engineers Without Borders USA allow students to work on community-based projects. Government programs like the USDA’s Natural Resources Conservation Service also provide volunteer positions for conservation projects.

What are the job prospects for environmental engineers?

The US Bureau of Labor Statistics projects a 7% employment growth for environmental engineers. This growth translates to about 3,000 job openings each year.

Environmental engineers work in a variety of industries, including government agencies, consulting firms, construction companies, and manufacturing. Depending on the role, they may focus on assessing environmental impact, designing pollution control systems, or ensuring regulatory compliance. For those looking to advance into leadership roles, pursuing the cheapest Masters in Engineering Management online can be a cost-effective way to gain management skills while continuing to work in the field. 

Common job titles include:

• environmental engineer
• water resources engineer
• environmental consultant
• environmental scientist

What is the best way to get an entry-level job in environmental engineering?

To get an entry-level job in environmental engineering, consider smaller firms and startups. Many job seekers focus on big companies, but smaller firms hire faster and offer more hands-on experience.

Temporary or contract roles are also a good way to start. Many companies hire for short-term projects like site assessments or compliance audits. These jobs often lead to full-time positions.

Showcasing your skills through independent projects is another great strategy. Create a portfolio with research, case studies, or environmental assessments. Employers value candidates who go beyond coursework. Publishing your work on LinkedIn or ResearchGate can attract attention.

Just like those exploring the paleontologist career path build their credentials through field digs, fossil analysis, and academic publications, aspiring environmental engineers can stand out by demonstrating practical experience and passion for sustainability early on.
