Rafat Abbasi, Robbie Ettinger, Zach Capehart, Mahsa Shayan, Ravi Arulanantham, and Rula Deeb and SiREM’s Sandra Dworatzek will contribute to the Association for Environmental Health and Sciences (AEHS) 35th Annual International Conference on Soil, Water, Energy, and Air, also known as AEHS West.

The conference will be held on March 16 through 19, 2026, in San Diego, California. Geosyntec is a sponsor of the event.

AEHS West is an environmental conference that brings together professionals from state and federal agencies, environmental engineering firms, consulting companies, industry, and academia to share cutting-edge research, innovative approaches, and practical insights.

The AEHS Foundation is a nonprofit professional organization that fosters communication and cooperation among professionals who assess, clean up, and protect soil, sediment, and water. The AEHS network spans professional disciplines, including biology, chemistry, geology, engineering, and regulatory science.
