Many sites have been required to add the analysis of PFAS to their ground water sampling plans. Military bases, airports, landfills and manufacturing facilities are sites where PFAS contamination may be present due to the use of PFAS in activities such as fire suppression, waste disposal, or industrial processes. Collecting samples for PFAS can be different from sampling for fuels, solvents, and other chemical contaminants, as potential sources of PFAS are nearly everywhere - in waterproof clothing and field gear, personal care products, and sampling equipment. But, is there really a risk from all of these sources? Do we need to eliminate all of these items to avoid sample contamination? And what about fluoropolymers like Teflon that have been used in sampling equipment for more than three decades? Can we use these systems to collect samples for PFAS analysis or do we need new equipment that is entirely free of all fluoropolymers?
Currently there is no standard method or protocols for sample collection, handling, or quality control measures outside of those referenced for potable water in the EPA drinking water methods. Specific attention must be paid to the protocols employed by the laboratory and the field sampling team.
In this webinar, David Kaminski with QED Environmental Systems will explore the sources of PFAS sample contamination and dispel some of the myths and speculation surrounding the issue. Taryn McKnight with Eurofins Environment Testing (EET) will catalog what research studies have shown us to date, what best practices to adopt, and what data gaps still exist.
