Two of three water-distribution systems that have historically supplied drinking water to family housing at U.S. Marine Corps Base Camp Lejeune, North Carolina, were contaminated with volatile organic compounds (VOCs). Tarawa Terrace was contaminated mostly with tetrachloroethylene (PCE), and Hadnot Point was contaminated mostly with trichloroethylene (TCE). Because scientific data relating to the harmful effects of VOCs on a child or fetus are limited, the Agency for Toxic Substances and Disease Registry (ATSDR), an agency of the U.S. Department of Health and Human Services, is conducting an epidemiological study to evaluate potential associations between in utero and infant (up to 1 year of age) exposures to VOCs in contaminated drinking water at Camp Lejeune and specific birth defects and childhood cancers. The study includes births occurring during the period 1968-1985 to women who were pregnant while they resided in family housing in Camp Lejeune. Because limited measurements of contaminants and exposure data are available to support the epidemiological study, ATSDR is using modeling techniques to reconstruct historical conditions of groundwater flow, contaminant fate and transport, and the distribution of drinking water contaminated with VOCs delivered to family housing areas. This report describes the three-dimensional simulation of the fate, degradation, and advective dispersive transport of PCE and associated degradation by-products - TCE, trans-1,2-dichloroethylene (1,2-tDCE), and vinyl chloride (VC)-within the Tarawa Terrace aquifer and Castle Hayne aquifer system at Tarawa Terrace and vicinity.
