Camp Lejeune, North Carolina: Water Modeling

Tarawa Terrace

The Agency for Toxic Substances and Disease Registry is the lead agency determining if exposures to PCE and TCE in drinking water are associated with adverse health outcomes among the children of Marines stationed at Marine Corps Base Camp Lejeune, North Carolina.

A new analysis shows that former Marines and their families who lived in Tarawa Terrace family housing units during the period November 1957 through February 1987 received contaminated drinking water containing the dry-cleaning solvent, tetrachloroethylene (PCE). Levels of PCE in the drinking water during this period exceeded the amount currently allowed by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act.

Exposure to PCE-contaminated drinking water occurred because PCE leaked into groundwater that supplied the Tarawa Terrace drinking water system from a dry-cleaner located outside the Camp Lejeune military base. In 1987, the military base shut down the Tarawa Terrace water treatment plant because of PCE contamination of the drinking water.

The following information helps explain the table listing the levels of tetrachloroethylene (PCE) and other chemicals that may have been in your drinking water during your tour of duty at Camp Lejeune.

  • Micrograms per liter (μg/L) is equivalent to parts per billion (ppb)


  • Two approaches to modeling the water system contaminants were used
    • The “MT3DMS” model is less complex and ignores the fact that PCE breaks down (or degrades) in the ground water to TCE, DCE and vinyl chloride
    • Because of concern by members of the affected community, a second model was used to estimate the amount of PCE degradation products (TCE, DCE and vinyl chloride) in the drinking water
      • This model requires more assumptions and is more complex
    • Both approaches provided similar results
