Geosyntec Practitioners to Contribute to WEFTEC 2025

Geosyntec practitioners will make significant contributions to the Water Environment Federation’s Technical Exhibition and Conference (WEFTEC) 2025 from September 27 through October 1, 2025, in Chicago, Illinois.

In addition, Geosyntec will host a booth at the WEFTEC Career Fair for Students and Young Professionals from 1:00 to 4:00 p.m. CT on Monday, September 29.

WEFTEC offers education and training to water-quality professionals from around the world. At the event, industry leaders, suppliers, and colleagues come together to explore, learn, network, grow professionally, and strengthen their connections to the water community.

The conference is sponsored by the Water Environment Federation (WEF), a nonprofit that provides technical education and training for thousands of water quality professionals who clean water and return it safely to the environment.
