Per- and Polyfluoroalkyl Substances (PFAS) in Municipal Solid Waste and Landfill Leachate

May 9, 2018 @ 2:00 pm - 3:30 pm

| Free

Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals that are commonly used in consumer and industrial products. There has been growing concern about the presence of the PFAS-containing products in landfills and potential occurrence of these compounds in leachate.

This 90-minute webinar will cover the following topics:

  • Overview of what exactly are PFASs
  • Regulatory concerns about PFASs from an environmental and exposure standpoint
  • Sources of PFASs and how they get disposed of in landfills
  • Fate within a landfill
  • Presence and potential treatability of PFASs in leachate



Scott Grieco, PhD, PE, Senior Technical Consultant and Emerging Contaminants Team Leader – CH2M

Dr. Grieco has over 26 years of experience in the evaluation, and design, and optimization of ground water remediation, leachate treatment, and industrial wastewater treatment systems.  Scott is a recognized Subject Matter Expert in physical/chemical treatment and separation technologies as applied to ex-situ ground water and industrial wastewater treatment. He has extensive process design experience in industrial wastewater, environmental waters (dredge water, sediment dewatering) and groundwater remediation treatment systems utilizing activated carbon, synthetic adsorbents, advanced oxidation processes, and membrane treatment processes.  He is an expert in treatment of environmentally persistent compounds such as PFAS, mercury, arsenic, selenium, and polychlorinated biphenyls (PCBs).  Scott is a peer-reviewer for Separations and Purification Journal and is an Adjunct Professor at SUNY ESF and Guest Lecturer at Syracuse University on environmental engineering and remediation.
