As an environmental engineer, you'll develop new solutions to ensure clean water, air and soil for the health of humans and the environment. This major will teach you how to treat tap water and wastewater, manage stormwater, and protect surface and groundwater sources. With a solid background in chemistry, biology, microbiology and core engineering classes, you will be well-prepared to tackle real-world challenges.

Our faculty have specialized expertise in areas like bioremediation of chlorinated solvents and emerging contaminants, sustainable biological wastewater treatment, the environmental impacts of nanoparticles and microplastics, and the persistence of antibiotic-resistant bacteria in wastewater systems.

After graduation, go on to design technologies to reduce and clean up pollution, recycle waste products, prevent contamination of our water and food supply, and preserve natural resources and habitats.

As a first-year student, Jackie Nguyen started working with Tala Navab-Daneshmand, assistant professor of environmental engineering, on a project to learn more about antibiotic-resistant bacteria in wastewater treatment facilities across Oregon. Jackie continued to work in the lab for four years. She presented her research at national, regional, and local conferences and has co-authored articles in peer-reviewed publications. 

My greatest achievement 
Ken Williamson, B.S. civil engineering ’68, M.S. environmental engineering ’70  joined the College of Engineering as an undergrad, stayed for his master’s degree, returned as a professor, and eventually became a school head. Now, a decade into his ‘retirement,’ he’s a key industry partner.

To become a CBEE graduate student you must be admitted to Oregon State University through both the Graduate School and the School of CBEE. The faculty in CBEE examine the material submitted to determine adequacy of academic background and to decide whether facilities in the School are adequate for the expressed aims of the student. The Graduate School will determine whether the general university conditions for admission have been met. Applicants will be notified by the Graduate School as to the action taken. A critical consideration in the decision is whether the applicant's academic objectives can be satisfactorily fulfilled. CBEE does not have the capacity to accommodate all applicants who meet the minimum admission requirements. Applicants to the school of CBEE graduate program must meet the OSU Graduate School's CBEE minimum admission requirements listed below, and submit a complete application package in order to be considered for admission https://gradschool.oregonstate.edu/admissions/process .

International students interested in the Master of Engineering (MEng) program should apply through Master's International Direct.

Only complete applications will be reviewed and considered for admission.

Application Cycles/Deadlines

CBEE only accepts students for the fall term.  We do not allow admissions for winter or spring terms.

  • Application deadlines for MS and PhD programs: Priority Deadline December 1, 2023, Final Deadline January 5th, 2024.
  • Applications deadline for MEng program: May 1, 2023.


The School of CBEE application process is highly competitive and we normally make no more than 5 offers of support (assistantships) per year. Applicants with a very strong record and particular aptitude for graduate research may be offered a term by term assistantship which provides a stipend and tuition remission. We cannot guarantee that you will always be awarded funding. These are offered the first of April for the upcoming school year and are chosen from the accepted applicants. Graduate assistants may work up to 20 hours per week during the academic year. If you are not awarded funding you should be prepared to be a self-supporting student. Also, due to the limited number of assistantships available, MEng students are not funded in this manner. Applicants to the School of CBEE do not need to complete a separate application in order to be considered for assistantships. A complete application consists of all the materials listed on the Graduate Application.

Grade Point Average

The School of CBEE requires a four-year baccalaureate degree (or international equivalent), a professional degree, or an appropriate U.S./Canadian alternative degree, from a regionally accredited (US) or recognized (International) college or university, with a cumulative B average (equivalent 3.00 on a U.S. 4.00 grading scale) on the most recent baccalaureate degree or any subsequent graduate degree from a regionally accredited (US) or recognized (International) college or university, plus all work completed thereafter.


The GRE is not required for application/admission into our programs.

Language Proficiency

The CBEE minimum TOEFL is 580 (237 computer, 92-93 iBT with a minimum score of 18 on each section). TOEFL must be less than two years old. The IELTS is accepted as well. The minimum score is 6.5. Language Proficiency tests are not required for US citizens or those who received their undergraduate degree from an English speaking country institution.

Applying for Admission

1. Materials that must be submitted electronically

  • Application for Graduate Admission: online application form Graduate Application(International students interested in the Master of Engineering (MEng) program should apply through Master's International Direct.)
  • Application Fee by credit card (part of online application)
  • Statement of Objectives: (part of online application)
  • Resume/CV
  • Recommendation Letters: You must provide the names and email addresses of three professional references as part of the degree-specific portion of the online application. The references will be sent instructions on how to submit their letters and you will receive an email with a link to manage those reference requests after submitting the application.
  • TOEFL: You must self-report your scores as part of the online application. You must also request that TOEFL send your scores to OSU. Scores must be no older than 2 years at the time when your graduate studies start.

One official copy of your final transcripts must be submitted to the Graduate School in order to complete the acceptance process. International applicants must provide a certified English translation of their academic transcripts.

Portrait of Lauren Crandon

“Every day is different, and you’re able to get involved in every aspect. You may be writing a research paper, performing an economic analysis, or in the lab running experiments.” – Lauren Crandon, Ph.D. environmental engineering ’18, research engineer at OnTo Technology. Read about Lauren’s experience at Oregon State.  

Jackie Wells is a master’s degree student in environmental engineering. She is working on a rain garden system to remove contaminants from stormwater. Jackie is advised by Tyler Radniecki, associate professor of environmental engineering.

Experiences of Nonbinary Students in Engineering  
In a recent episode of the SWE Diverse podcast, Andrea Haverkamp (Ph.D. environmental engineering ’21) talks about her research project exploring the experiences of transgender and gender-nonconforming students in engineering and computer science, such as their sources of community support and collective resilience in the face of adversity.

Oregon State University scientists find tiny tire particles can harm aquatic life
