Environmental engineers are encouraged to become licensed as a professional engineer (PE). Licensure generally requires the following:
A degree from an engineering program accredited by ABET
A passing score on the Fundamentals of Engineering (FE) exam
Relevant work experience
A passing score on the Professional Engineering (PE) exam
The initial FE exam can be taken after graduation. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After getting suitable work experience, EITs can take the second exam, called the Principles and Practice of Engineering.
Several states require continuing education for engineers to keep their licenses. Most states recognize licensure from other states if the licensing state's requirements meet or exceed their own requirements.
After licensing, environmental engineers can earn board certification from the American Academy of Environmental Engineers and Scientists. This certification shows that an environmental engineer has expertise in one or more areas of specialization.
Chemical engineers apply the principles of chemistry, biology, physics, and math to solve problems that involve the production or use of chemicals, fuel, drugs, food, and many other products. They design processes and equipment for large-scale safe and sustainable manufacturing, plan and test methods of manufacturing products and treating byproducts, and supervise production.
Civil engineers design, construct, supervise, operate, and maintain large construction projects and systems, including roads, buildings, airports, tunnels, dams, bridges, and systems for water supply and sewage treatment.
Environmental engineering technicians carry out the plans that environmental engineers develop. They test, operate, and, if necessary, modify equipment used to prevent or clean up environmental pollution. They may collect samples for testing, or they may work to mitigate sources of environmental pollution.
Environmental scientists and specialists use their knowledge of the natural sciences to protect the environment and human health. They may clean up polluted areas, advise policy makers, or work with industry to reduce waste.
Natural sciences managers supervise the work of scientists, including chemists, physicists, and biologists. They direct activities related to research and development, and coordinate activities such as testing, quality control, and production.
