What Is Environmental Engineer?

Environmental engineers work to prevent, control or remediate any hazards to the environment using their engineering expertise. Their work might focus on topics like waste disposal, erosion, and water and air pollution.

“Most people really don’t know what environmental engineers do,” says Dan Wittliff, managing director of environmental services with GDS Associates in Austin, Texas. They hear “environmental engineer,” and they often think “environmentalist,” he adds.

“It’s not only about Earth Day and environmental consciousness,” Wittliff says. “Those can be part of what an environmental engineer does, but in terms of what an environmental engineer does a day in and day out, you’re really focused on what the regulations say, what you’re required to do to meet those regulations and how you’re going to do it, (while also bearing in mind) the cost and the timeline.”

The Bureau of Labor Statistics projects 5.1 % employment growth for environmental engineers between 2018 and 2028. In that period, an estimated 2,900 jobs should open up.
