Environmental and Ecological Engineering, BSEEE

Location(s): West Lafayette


About the Program


The BS program in Environmental and Ecological Engineering (EEE), housed in the School of Sustainability Engineering and Environmental Engineering (SEE), is accredited by the Engineering Accreditation Commission of ABET, under the commission’s General Criteria and Program Criteria for Environmental Engineering and Similarly Named Engineering Programs. Our multidisciplinary faculty rigorously prepare students to address the issues that environmental engineers traditionally consider and to proactively prevent environmental problems. 

  • Coursework:  Undergraduate coursework in EEE focuses on environmental issues, ecological interactions, the complexity and connectivity between systems, and “designing for the environment.” Topics include systems modeling, urban ecology, industrial sustainability, environmental modeling and remediation, and life-cycle analysis, soil and water resource engineering, global and environmental issues, water and wastewater treatment, hydrology, disaster and emergency relief, habitat restoration, air pollution control and design, and climate action initiatives. 

  • Integrated mentorship:  EEE’s mentoring program is an integrated partnership that emphasizes one-on-one attention. Each student is assigned an EEE advisor to discuss academic and personal concerns, and paired with a faculty mentor to provide guidance in identifying research interests and pursuing long-term goals. 

  • Flexible plans of study:  An advisor and faculty mentor work with each student to craft an individualized plan of study. Students complete extensive elective coursework in addition to the core curriculum, enabling each degree to be tailored strategically to individual interests and career plans. 

  • Experiential learning:  Our students participate in a broad range of hands-on learning activities, including cooperative education, undergraduate research, study abroad programs, internships, and service learning. 

  • Community:  EEE undergraduates are a close-knit group of students who prioritize peer support over competition. Our program’s female enrollment is 50 percent, among the largest percentages of female students in any College of Engineering major. 

  • Strong career opportunities: The job placement rate and starting salary range EEE graduates are commensurate with those for other College of Engineering majors. EEE graduates are equipped to enter a wide range of employment sectors in environmental and engineering fields, such as consulting and engineering services, manufacturing, industrial and construction, government, municipal and public service, non-governmental organizations (NGOs), and academia.

Non-Course/Non-Credit Requirements


Experiential education at Purdue University is a planned pedagogy centering on an authentic experience to strengthen students’ knowledge, skills, and abilities, paired with student reflection.

Participation in an experiential education opportunity is expected in EEE, and necessary prior to enrolling in EEE 48100: Reflective Practitioner, a required major course in the senior year. 
Experiential education may include internships/co-ops, clinical placements and other field-based experiences, projects with community/industry partners, and undergraduate research. Not all experiences are course-based. Some common examples are listed here, but are not limited to: 
  • EPCS, VIP, GEP - any course level, and any credit level 
  • EEE 29199, 29299, 39399, 39499, 39599, 38199, 38299, 38399, 39699 - all EEE Coop/Internship courses

  • EEE 47200 - real-world, client-based service-learning design experience 
  • Study Abroad - any course level, any credit level, any time duration 

GPA Requirements


  • A GPA of 2.0 is required for all Baccalaureate degrees.
  • A 2.0 GPA is required in College of Engineering courses at the 20000-level and above.

Pass/No Pass Policy


  • Courses with a Pass/No Pass grade (P/NP) may not be used to satisfy degree requirements. 

Transfer Credit Policy


  • If you are interested in registering for a course offered by a different institution, please review the information on the Purdue Office of the Registrar Transfer Credit website. 
     * If you are an admitted transfer student, please review the above Transfer Credit website and then work with your academic advisor to determine exactly how your previous courses might apply.

World Language Courses


World Language proficiency requirements vary by program. The following list is inclusive of all world languages PWL offers for credit; for acceptable languages and proficiency levels, see your advisor. (ASL-American Sign Language; ARAB-Arabic; CHNS-Chinese; FR-French; GER-German; GREK-Greek(Ancient); HEBR-Hebrew(Biblical); HEBR-Hebrew(Modern); ITAL-Italian; JPNS-Japanese; KOR-Korean; LATN-Latin; PTGS-Portuguese; RUSS-Russian; SPAN-Spanish)

Critical Course


The ♦ course is considered critical.

In alignment with the Degree Map Guidance for Indiana’s Public Colleges and Universities, published by the Commission for Higher Education (pursuant to HEA 1348-2013), a Critical Course is identified as “one that a student must be able to pass to persist and succeed in a particular major. Students who want to be nurses, for example, should know that they are expected to be proficient in courses like biology in order to be successful. These would be identified by the institutions for each degree program.”

Disclaimer


The student is ultimately responsible for knowing and completing all degree requirements. Consultation with an advisor may result in an altered plan customized for an individual student. The myPurduePlan powered by DegreeWorks is the knowledge source for specific requirements and completion.
