Background
Per- and polyfluoroalkyl substances (PFAS) present unique challenges in groundwater systems, setting them apart from conventional contaminants like trichloroethylene (TCE) or benzene. PFAS’s distinct chemical and physical properties necessitate specialized investigative approaches. These substances are characterized by environmental persistence, resistance to traditional remediation techniques, and complex, still-evolving toxicological profiles. Understanding PFAS chemistry, toxicology, and environmental behavior is crucial for effective site characterization and remediation strategies.
The course
This 3-4 hour course aims to impart an in-depth understanding of PFAS-related environmental concerns, focusing on conceptual models and characterization goals essential for remedial investigations at PFAS-impacted sites. The course outline includes:
· The PFAS Problem: An overview of the environmental impact and significance of PFAS contamination.
· PFAS Chemistry, Toxicology, and Conceptual Models: Detailed exploration of PFAS properties, health implications, and the development of effective conceptual models for site investigation.
· PFAS Fate and Transport Modeling: Discussing the challenges in predicting PFAS behavior and risk in the environment.
· The PFAS Retention Paradigm: A brief overview of how PFAS interacts with different environmental matrices.
· Characterizing PFAS Sites: Understanding what makes PFAS site characterization different from conventional pollutants.
· Key Site Characterization Goals: Focusing on PFAS mass discharge and travel time estimation.
· Case Studies on High Resolution Site Characterization and Mass Discharge: Practical examples highlighting the approaches and methodologies in PFAS site characterization.
· New Challenges: PFAS in Stormwater and Surface Water: Exploring emerging issues and investigative strategies. Surface Water Investigations: Case studies providing insights into PFAS impact and management in surface water environments.
The course will emphasize that remedial investigations at PFAS-impacted sites require distinct, tailored approaches compared to traditional methods for other groundwater contaminants. Participants will gain a comprehensive conceptual understanding and practical knowledge for addressing PFAS contamination, including the importance of site-specific models, the behavior of PFAS in the environment, and innovative strategies for characterization and mitigation, especially in groundwater systems.
