Deal with People
Environmental engineers use the principles of engineering, soil science, biology, and chemistry to develop solutions to environmental problems. They are involved in efforts to improve recycling, waste disposal, public health, and water and air pollution control. They also address global issues, such as unsafe drinking water, climate change, and environmental sustainability.Duties
Environmental engineers typically do the following:
Environmental engineers conduct hazardous-waste management studies in which they evaluate the significance of a hazard and advise on treating and containing it. They also design systems for municipal and industrial water supplies and industrial wastewater treatment, and research the environmental impact of proposed construction projects. Environmental engineers in government develop regulations to prevent mishaps.
Some environmental engineers study ways to minimize the effects of acid rain, climate change, automobile emissions, and ozone depletion. They also collaborate with environmental scientists, planners, hazardous waste technicians, and other engineers, as well as with specialists such as experts in law and business, to address environmental problems and environmental sustainability. For more information, see the job profiles on environmental scientists and specialists, hazardous materials removal workers, lawyers, and urban and regional planners.
Environmental engineers must have a bachelor’s degree in environmental engineering or a related field, such as civil, chemical, or general engineering. Employers also value practical experience. Therefore, cooperative engineering programs, in which college credit is awarded for structured job experience, are valuable as well.Education
Entry-level environmental engineering jobs require a bachelor’s degree. Programs include classroom, laboratory, and field studies. Some colleges and universities offer cooperative programs in which students gain practical experience while completing their education.
At some colleges and universities, a student can enroll in a 5-year program that leads to both a bachelor’s and a master’s degree. A graduate degree allows an engineer to work as an instructor at some colleges and universities or to do research and development, and some employers prefer candidates to have a master’s degree.
Students interested in becoming an environmental engineer should take high school courses in chemistry, biology, physics, and math, including algebra, trigonometry, and calculus.
Many engineering programs are accredited by ABET. Some employers prefer to hire candidates who have graduated from an accredited program. A degree from an ABET-accredited program is usually necessary for a person to become a licensed professional engineer.Important Qualities
Imagination. Environmental engineers sometimes have to design systems that will be part of larger ones. They must be able to foresee how the proposed designs will interact with other components of the larger system, including the workers, machinery, and equipment, as well as with the environment.
Interpersonal skills. Environmental engineers must be able to work with others toward a common goal. They usually work with engineers and scientists who design other systems and with the technicians and mechanics who put the designs into practice.
Problem-solving skills. When designing facilities and processes, environmental engineers strive to solve several issues at once, from workers’ safety to environmental protection. They must be able to identify and anticipate problems in order to prevent losses for their employers, safeguard workers’ health, and mitigate environmental damage.
Reading skills. Environmental engineers often work with businesspeople, lawyers, and other professionals outside their field. They frequently are required to read and understand documents with topics outside their scope of training.
Writing skills. Environmental engineers must be able to write clearly so that others without their specific training can understand their plans, proposals, specifications, findings, and other documents.Licenses, Certifications, and Registrations
Licensure is not required for entry-level positions as an environmental engineer. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one’s career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. State licensure generally requires
The initial FE exam can be taken after one earns a bachelor’s degree. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering.
Several states require continuing education in order 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.Advancement
As beginning engineers gain knowledge and experience, they move on to more difficult projects and they have greater independence to develop designs, solve problems, and make decisions. Eventually, environmental engineers may advance to become technical specialists or to supervise a team of engineers and technicians.
Some may even become engineering managers or move into executive positions, such as program managers. However, before assuming a managerial position, an engineer most often works under the supervision of a more experienced engineer.
