Our practitioners will chair seven sessions, conduct six platform presentations, and present seven posters. Visit Geosyntec at booth 308 and SiREM at booth 420 to learn how we can help remediate sediments in aquatic environments. Geosyntec is a sponsor of the event.
The 2025 Sediments Conference is a forum for sharing research results, practical experiences, and innovative approaches to investigating, remediating, and restoring the environmental and economic vitality of waterways and aquatic systems.
