Computing & Engineering

Environmental Engineering major, explained.

Engineer practical systems that protect environmental and human health.

Environmental Engineering explores how chemistry, biology, hydrology, infrastructure, modeling, treatment systems, and regulation address water, air, waste, and pollution. Students commonly study Water and wastewater treatment, Air pollution control, Environmental chemistry, Hydrology, and Environmental systems design. Programs vary by college, but the field generally combines foundational ideas with applied work so students can investigate meaningful questions, make informed decisions, and communicate what they discover.
