Perfluoroalkyl Substances (PFAS) are a large family of synthetic chemicals used in a wide variety of products including fire-fighting foams, food packaging, and non-stick coatings. These compounds are also present in equipment used in standard environmental sampling efforts. Recent U.S. EPA Health Advisory Levels have been set at 70 parts-per-trillion and some states have set significantly lower regulatory requirements for allowable drinking water concentrations. The very low regulatory requirements require analysis of this common compound to levels of one to two parts-per-trillion. The concentrations at which PFAS must be analyzed and the ubiquity of these compounds in many common products require special precautions be taken to ensure, and to demonstrate, that samples are not biased during collection, transport, and analysis. State of the practice sampling and analysis considerations will be described in this presentation.

Andy Horn has been an environmental and water resource consultant for over 25 years and is currently a member of the National Groundwater Association Best Suggested Practices Task Group developing a guidance document series on PFAS. Andy has performed hydrogeologic investigations on hazardous waste sites and facilities including US EPA Superfund, manufacturing, fueling & maintenance, and chemical storage & distribution and for basic scientific research. Andy’s areas of expertise include data collection program design and management, data analysis and synthesis, and study results reporting and presentation. Andy has worked on a variety of projects across the U.S. He earned his Bachelor of Science in Geology from the University of Alabama and his Master of Science degree from the University of Colorado. Andy is a registered professional geologist in Kansas.
