Eric Dickenson, Associate Guest Editor
Eric is a project manager for the Water Quality and Research and Development section at the Southern Nevada Water Authority. He has more than 20 years of experience in the treatment of traditional and emerging chemical contaminants. His recent research, peer-reviewed publications, and invited presentations have focused on the occurrence and treatment of PFAS in drinking water, wastewater, and potable reuse applications. Eric has led as principal investigator (PI) or co-PI on multiple PFAS-focused projects funded by The Water Research Foundation, Department of Defense’s Strategic Environmental Research and Development Program, US Department of Agriculture, and US Environmental Protection Agency. He recently served on the National Water Research Institute’s independent advisory panel that provided guidance for direct potable reuse regulations for the State of Colorado.
Dickenson received a BS in chemical engineering from the University of California, Davis, and an MS and PhD in civil engineering from the University of Colorado, Boulder.
Jennifer Guelfo, Associate Guest Editor
For the past 10 years, Jennifer’s research has focused on PFAS in the environment. She is the principal investigator (PI) or co-PI on projects related to PFAS occurrence, fate, and treatment of PFAS in landfill leachate, wastewater, and firefighting foam-impacted soil and groundwater funded by the Department of Defense’s Strategic Environmental Research and Development Program, the US Environmental Protection Agency, and the Water Resources Foundation. In addition to academia, Jennifer also has a combination of consulting and industry experience, and she uses this background to engage in activities that can inform policy and bridge gaps between research and practice.
Jennifer earned her BA degree in geology at the College of Charleston, her MS and PhD degrees from the Colorado School of Mines, and she completed a postdoctoral appointment at Brown University. She is an assistant professor in the Civil, Environmental, and Construction Engineering Department at Texas Tech University.
Detlef Knappe, Associate Guest Editor
Detlef has conducted research in the field of water quality and treatment for more than 30 years. Ongoing research focuses on developing analytical methods for the characterization of water quality and evaluating/developing treatment approaches for the control of organic contaminants. At North Carolina State University, Detlef is a member of the Center for Human Health and the Environment and deputy director of the Superfund Research Program’s Center for Human and Environmental Health Effects of Per- and Polyfluoroalkyl Substances (PFAS). Detlef is a member of the North Carolina Secretaries’ Science Advisory Board (convened by the Secretaries of the North Carolina Departments of Environmental Quality and Health and Human Services) and serves as trustee of the Water Science and Research Division of AWWA.
