Tackle the world’s most pressing environmental problems with a major in Environmental Chemistry.

You’ll learn the impact that chemical substances have on the earth’s ecosystems by building your knowledge of both chemistry and environmental science. Get ready to confront climate change, find ways to clean up air and water pollution, and respond to environmental disasters. Or figure out solutions to problems related to energy, waste and recycling.

You’ll join a student-faculty research group for at least two semesters, where you’ll learn the process of research from beginning to end. Apply your knowledge in the state-of-the-art labs of the John Brooks Williams Natural Sciences Center. Graduate with a solid understanding of the science — and the connections between the environment, economics and policy.

You’ll leave St. Edward’s ready to make a difference.

A few examples of courses students in this major take:             

  • Environmental Politics and Policy – Explore new demands worldwide for dealing with the risks of climate change, population growth, loss of biological diversity and terrorism, which will force governments everywhere to rethink policy strategies and find new ways to reconcile environmental and economic goals.
  • Thermodynamics and Kinetics – A rigorous consideration of thermodynamics, statistical mechanics and chemical kinetics.
  • Biochemistry – Survey of the fundamentals of biochemistry. Topics include structure of proteins, lipids and carbohydrates, catalysis, kinetics, bioenergetics and metabolism, and information pathways.

Our Faculty and Student Support Services

“As a scientist, it is my goal to explore the natural world through the lens of chemistry and contribute to the global community of scientific explorers. As a teacher and mentor, I hope to guide students through this never-ending journey of exploration they will continue well beyond their years at St. Edward’s.”

– Santiago Toledo, Assistant Professor of Chemistry

Student Support Services

Along with personal attention and mentorship from their professors, our students have access to offices and programs outside of the classroom that support their success. We encourage students to take advantage these resources that help them thrive and excel:

  • Academic counseling and advising
  • Supplemental instruction and tutoring
  • Career preparation and advising 
  • Writing Center consultation
  • Health and wellness counseling
  • Student disability support

Outside the Classroom

We emphasize experiential learning, so students majoring in Environmental Chemistry enroll in at least two semesters of research courses and join a student-faculty research group with the goal of producing and presenting professional-level work.

On Campus Projects

Students may also participate in [insert types of projects/ opportunity] on campus. For example, six students in an installation art class with professor Alexandra Robinson created an interactive art installation for high-school students visiting campus [provide an example from your major, as available].


Our internship program acquaints students with practical experience. Our students have recently interned with:

  • Tetra Tech
  • Texas Commission on Environmental Quality
