Environmental Engineer Job Descriptions, Average Salary, Interview Questions

What Does an Environmental Engineer Do?

Environmental engineers design systems and components to reduce the negative impact on the environment. They work on the challenges of pollution, waste management, air quality, and more. They conduct research on the environmental impact of projects, analyze data, and implement quality control checks to ensure environmental policies and standards are met. They use extensive knowledge of engineering principles, soil science, biology, and chemistry to create technically sound solutions to environmental problems. Some environmental engineers serve as technical advisors to ensure regulatory applicability. 

An environmental engineer must have good collaboration skills as they work closely with scientists, planners, and other experts. They need good verbal and written communication skills to provide recommendations, write reports, and document plans and standard operating procedures. They need to be proficient in relevant analytical and compliance software such as SAS or Autocad, be able to see the big picture, and be familiar with all environmental rules, regulations, and best practices. Environmental engineers develop real environmental and ecological improvement in their cities, regions, and beyond.
