PFAS: Investigating Wastewater & Septic Systems as the Source (webinar)

Dr. Jennifer Harfmann, New Hampshire DES presented Presence of PFAS in Domestic Wastewater & Potential Sources [PDF]. Jennifer highlighted a case study of monthly PFAS sampling from a residential community septic system in NH to estimate a typical domestic PFAS signature and per capita load of PFAS to the environment. She also discussed upcoming research to refine the estimate and identify key household products and activities contributing to PFAS in domestic wastewater.

Brittany O’Brien-Drake & Jasmine Stefansky, New York State DEC presented Two Case Studies: Exploring Commercial, Industrial, & Wastewater Sources of PFAS [PDF]. Brittany and Jasmine presented investigations into the sources of PFAS contamination of drinking water wells at two sites with no obvious suspected sources. Investigations included: hydrogeologic characterization, including borehole geophysics; environmental media sampling at suspected sources; septic tracer sampling; and PFAS fingerprinting.
