Geosyntec to Showcase Technical Leadership at Battelle's 2016 Chlorinated Conference

As in previous years, Geosyntec will make a significant technical contribution to the Tenth International Conference on Remediation of Chlorinated and Recalcitrant Compounds at the Palm Springs Convention Center in Palm Springs, California on May 22-26 2016.

The activities of our 26 attendees will include six session chairs, 27 platform presentations, two panel moderators, 21 poster presentations, and a display in booth 405 at the exhibition hall.

The conference will provide a robust technical program as well as the opportunity to network with environmental professionals from around the world. The conference is planned to be large as well with 930 platform talks and poster presentations scheduled in 71 specialized sessions, 10 panel discussions on key topics, over 100 exhibitors, a student mixer, 8 short courses, and multiple informal networking opportunities. Attendance is expected to be 1,500 to 1,700 scientists, engineers, regulators, and other environmental professionals representing universities, government site management and regulatory agencies, and R&D and manufacturing firms from more than 30 countries.
