PFAS in Groundwater Workshop: The Professional’s Challenge (#139)

Register Now

Date: December 5, 2019
Location: Las Vegas, Nevada

Overview:

Designed to be highly participative, this NGWA workshop will address and sharpen the thought processes of practitioners regarding how to apply scientific and legal considerations to sites contaminated with per- and polyfluoroalkyl substances (PFAS), a unique class of emerging contaminants widespread in groundwater and surface water, which, due to their toxicological characteristics, are increasingly the focus of environmental protection agencies worldwide.

PFAS include several thousand individual chemical compounds, each with at least one carbon-fluorine (C-F) bond and most of which are soluble in groundwater. The C-F bond is one of the strongest chemical bonds in nature. While useful in a wide variety of applications, the unique C-F chemistry of PFAS also creates significant challenges in water treatment and remediation. The fate, transport, and chemical transformations of most PFAS in the environment are still unknown and are areas of active scientific research.

This one-day workshop will include an opening presentation followed by group work sessions and discussions designed to improve analytical and problem-solving skills.

Those who complete the workshop will receive the PFAS Site Assessment and Remediation Certificate, which:

  • Demonstrates the ability to analyze a site for the potential presence of PFAS
  • Demonstrates an awareness of current PFAS information in the scientific and regulatory arena
  • Identifies data gaps in site assessments needed to recommend mitigation options such as containment or remediation
  • Devises a remediation plan including, but not limited to, treatment technologies, communicating risk, and quantifying cost benefit in the context of regulation.
