Developing an Approach to Groundwater DQRA for PFAS

Per- and poly-fluoroalkyl substances (PFAS) are a broad group of synthetic fluorinated chemicals which are persistent in the environment. Some are bio-accumulative and toxic, and/or highly mobile. PFAS are used in a wide variety of consumer products and industrial applications because of their unique chemical and physical properties, including oil, water and stain repellence, temperature and chemical resistance, and surfactant properties. PFAS are widespread within the water environment because of the direct and in...
