Larkspur Landing - Main Conference Room 1701 East Valley Road, Renton, WA 98055 [directions]
Course Reviews (4.8/5):
Abstract: This course provides a practical overview of contaminant behavior in soil and groundwater with an emphasis on petroleum, chlorinated solvents, per- and polyfluoroalkyl substances (PFAS), and metals. The material is intended for consultants and regulators managing contaminated sites. Course content is constantly updated and includes new approaches for characterizing contaminant distribution and hydrogeology in the subsurface.
Note: This course is preceded by the Chemistry Refresher for Environmental Professionals on November 19, 2019, which is recommended for those seeking a review of environmental chemistry principles. Attendees of both classes receive the group rate ($640 for 3 days of training).
