Presentation Abstract

Our understanding of the class of chemicals known as per- and polyfluoroalkyl substances, or PFAS, is rapidly evolving both here in Minnesota, in the US, and around the world.  PFAS have gained attention globally because some of them are highly persistent, soluble, mobile, and potentially harmful at even extremely low concentrations in drinking water.  Minnesota has been one of the epicenters of PFAS investigations in the US, having discovered PFAS contamination of groundwater in the east metro area in 2003 where the drinking water of over 140,000 people has been affected.  We’ll look at the current status of the on-going investigations in the east metro, touch on several other sites that have been identified in the state, and discuss the state’s efforts to create a ranked system to identify and evaluate other potential PFAS sources/sites.  Using case studies from several sites, we’ll also cover some of the unique fate and transport aspects of these highly persistent and mobile chemicals. This talk will also provide an update on recent state and national developments in PFAS risk assessment, regulation, and treatment technologies. 


Speaker Biography

Ginny Yingling is a senior hydrogeologist in the Environmental Health Division of the Minnesota Department of Health. She works with a team of Health Risk Assessors to evaluate human exposures to harmful chemicals in drinking water related to man-made contaminated sites.  Since 2003, she has been the agency’s lead investigator of PFAS.  She has a BS and MS in geology (from Penn State and University of Wyoming, respectively) and over 25 years of experience working on contaminated sites - first as an environmental consultant, then at the Minnesota Pollution Control Agency, and at the Department of Health since 2000. 


Ginny is also the co-chair of the Interstate Technology and Regulatory Council’s PFAS Team, a group of over 400 environmental professionals drawn from state and federal agencies, academia, industry, consulting, and public interest groups.  The team has developed a series of seven factsheets on PFAS, conducts PFAS training events, is developing a PFAS risk communication tool-box, and is preparing a detailed report on the current state of knowledge regarding PFAS.
