Courses identified as option electives allow students to learn about a specific topic in more depth. Option electives are grouped into four different focus areas as shown below. Environmental engineering students are required to complete 9 credits of option electives (generally three 3‐credit courses). Check with the Undergraduate Program Director before registering for an option elective course that is not on the approved list of option electives below.
