Superfund Research Program
Project Leader: Alexander F. van Geen
Grant Number: P42ES010349
Funding Period: 2000-2021
The Columbia Superfund Research Program’s Hydrogeology Core continues to generate hydrogeological data needed to how fast and how far an As contaminated plume spreads beyond its source. In the Cohort Study of Health Effects of Arsenic Longitudinal Study area in Bangladesh, where most of the Alexander van Geen’s, Ph.D., activities are concentrated as well, this Core supports on-going field work and contributed to the modeling of groundwater flow into the intermediate low-arsenic aquifer in the area that has been tapped to lower exposure by the installation of thousands of private wells (Mihajlov et al., in review; Mozumder et al., in review). The Hydrogeology Core Laboratories support for field studies under Benjamin Bostick, Ph.D., at the Lot 86 Superfund sites on the North Carolina State University campus was carried over to the next year because of an unanticipated delay in obtaining state approval for a deviation from the Record of Decision.
