About Environmental Engineers

Environmental Engineers develop solutions to environmental problems including air and water pollution, contaminated site remediation, waste management, and sustainability. They apply engineering principles alongside biology, chemistry, and ecology to design systems that protect human health and the natural environment. In water and wastewater engineering, they design treatment plants, distribution systems, and stormwater management infrastructure. In air quality, they design emission control systems for industrial facilities and model pollutant dispersion. In contaminated site remediation, they assess the extent of soil and groundwater contamination, design cleanup systems, and oversee remediation contractors. Environmental engineers must navigate complex regulatory frameworks—Clean Air Act, Clean Water Act, RCRA, CERCLA—and often interact with federal and state environmental agencies. They prepare environmental impact assessments for development projects, conduct environmental compliance audits for industrial operations, and develop environmental management systems. Increasing focus on climate change has expanded the role into greenhouse gas accounting, carbon management, and resilience planning.
