May 9, 2019, 8 A.M. to 5 P.M. (1 Day)
Quality Inn - Conference Center
1274 N. Atherton Street, State College, PA 16803 [directions]
Overview: This course provides an introduction to managing per- and polyfluoroalkyl substances (PFAS) contamination in the environment. PFAS have been in use since the 1940s, resist degradation, and are becoming increasingly regulated. The training begins with a review of PFAS sources, toxicity, and the common forms detected in the environment including perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), newer GenX related chemicals including hexafluoropropylene oxide (HFPO) dimer acid, and perfluorobutane sulfonic acid (PFBS). The course then focuses on more advanced topics including PFAS transport and fate, site assessment methods, and effective remediation strategies.
Note: This course is preceded by the Chlorinated Hydrocarbon Remediation Principles and Technologies course May 7 - 8, 2019 at the same location. This class is recommended for those seeking an improved understanding of chlorinated hydrocarbon remediation (e.g., PCE, TCE, 1,1,1-TCA, etc.). You may register for both classes in the series at the same time.
