Abstract
Polyfluoroalkyl substances (PFAS), more commonly known as forever chemicals, are a widespread group of environmental contaminants, commonly coming from fire fighting foams. The current detection methods for these compounds entail a long wait time and high costs. Our research uses fluorescent compounds as a means of rapid field detection for these compounds in environmental soil and water samples. Samples are combined with a solution of the fluorophore and methanol and tested both visually and by fluorometer. Through the use of fluorometry and visual testing, the presence (or absence) of significant PFAS concentrations can be determined from a fluorescence shift from green to blue light in a matter of seconds. This methodology will allow for much more time and cost effective PFAS field testing for both initial evaluation and for remediation effectiveness.
