The 2024 Symposium was held at the Muckleshoot Casino Resort in Auburn, Washington, April 22-25, 2024.

Thank you to all who contributed to the success of this biennial Symposium, which attracted 235 registrants. Eighteen Sponsors and Exhibitors displayed their cutting-edge technology and offered information on licensing and available resources. 

Field trips to the Pierce County Clear Creek Habitat restoration site and Lake Tapps/Geyser State Park kicked off the Symposium on Monday, followed by two days of presentations, panels, posters, and keynote speakers. The Symposium was followed by a day of workshops on Washington State Water Law and Water Rights, optimizing water wellfield performance, using Python in Hydrogeology, and Ex Situ/In Situ Treatment for PFAS. 

Participants had the opportunity to network with colleagues at the Tuesday evening reception, the two lunches, refreshment breaks, and a fantastic raffle with extraordinary prizes. Scholarships were also awarded to accomplished students in Washington State.
