The Agency for Toxic Substances and Disease Registry (ATSDR) is conducting an epidemiological study to evaluate whether exposures (in-utero and during infancy - up to 1 year of age) to volatile organic compounds that contaminated the drinking water at the U.S. Marine Corps Base Camp Lejeune, North Carolina, were associated with specific birth defects and childhood cancers that are observed at the site. The study includes the births that occurred to women who were pregnant while they resided in the family housing at the base during the period 1968 - 1985. There is no exposure data and very limited site-specific contamination data are available to support the epidemiological study. As a result, ATSDR is using modeling techniques to estimate the historical and present-day contamination conditions in the groundwater and the water treatment plant at Camp Lejeune, North Carolina. Owing to the complexity of the historical reconstruction process, a number of reports are being prepared to provide a comprehensive description of information and data used in historical reconstruction and present-day analyses at Tarawa Terrace and vicinity. To complement these studies, this report describes the effect of groundwater pumping schedule variations on the arrival times of Tetrachloroethylene (PCE) at water-supply wells and the water treatment plant (WTP).
This report is based on the work conducted in Multimedia Environmental Simulations Laboratory in the School of Civil and Environmental Engineering, Georgia Institute of Technology.
