PFAS in Groundwater Workshop: The Professional’s Challenge (#138)

Date: August 14-15, 2018
Location: St. Paul, Minnesota

As of July 18, this work shop is sold out. To be added to a waiting list, pending any cancellations, please phone NGWA customer service at (800) 551-7379 or (614) 898-7791. Thank you!

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.

While focusing on the current state of knowledge and practice regarding the fate, transport, and remediation of these chemical compounds, additional presentations will address the legal and regulatory requirements at PFAS-contaminated sites and drinking water systems, and how to effectively communicate risks.
