The news cycle is dominated by the COVID-19 virus, and many environmental professionals are fielding questions about the fate and transport of viruses and other pathogens in groundwater. To provide factual information on this topic, GRA has reached out to two leading experts, Dr. Ken Bradbury at the University of Wisconsin and Dr. Mark Borchardt at the USDA Agricultural Research Service to share their work on the transport of human enteric viruses in the subsurface. Human enteric viruses are derived primarily from human and animal wastes, and have been detected in groundwater samples from many water supply wells throughout the U.S. Attenuation mechanisms for viruses and other pathogens in the subsurface are different than for dissolved contaminants, and artificial conduits (e.g., abandoned water wells) can quickly convey enteric viruses to significant depths in drinking water aquifers. While this presentation will focus on the fate and transport of enteric viruses in the subsurface, the presenters will share their thoughts on the fate and transport of the COVID-19 virus and other pathogens in groundwater during a question & answer session immediately following their presentation.
