of the Tarawa Terrace drinking water system
at U.S. Marine Corps Base Camp Lejeune, North
Carolina that former Marines and their families
who lived in Tarawa Terrace family housing units
during the period November 1957 through February
1987 received drinking water contaminated with
the dry-cleaning solvent tetrachloroethylene
(PCE) at levels above the current maximum contaminant
level (MCL) of 5 ppb. [PDF, 2190KB]

Chapter
C
This report, Chapter C, describes
the development and calibration of a digital
model applied to the simulation of groundwater
flow within the Tarawa Terrace aquifer and Upper
Castle Hayne aquifer system at and in the vicinity
of the Tarawa Terrace housing areas. [PDF, 5347KB]
Chapter
D
The Chapter D report provides abridged
information describing the most salient properties
and biodegradation of 27 chlorinated volatile
organic compounds detected during groundwater
studies in the United States. This information
is condensed from an extensive list of reports,
papers, and literature published by the U.S.
Government, various State governments, and peer-reviewed
journals. The list includes literature reviews,
compilations, and summaries describing volatile
organic compounds in ground water. [PDF, 2274KB]
Chapter
E
This report, Chapter E, describes
the occurrence and distribution of tetrachloroethylene
and related contaminants within the Upper Castle
Hayne Aquifer System at and in the vicinity
of the Tarawa Terrace housing area. There also
is a brief description of the occurrence and
distribution of benzene, toluene, ethylene,
and xylene (BTEX) and related compounds. [PDF,

Chapter
F
This report, Chapter F, describes the development and calibration of a digital model applied to the simulation of the fate and transport of tetrachloroethylene (PCE) within the Tarawa Terrace aquifer and the Castle Hayne aquifer system at and in the vicinity of the Tarawa Terrace housing area, U.S. Marine Corps Base Camp Lejeune, North Carolina.

Table of Simulated Concentrations of PCE
This table lists the levels of
tetrachloroethylene (PCE) and other chemicals
that may have been in your drinking water during
your tour of duty at Camp Lejeune. [PDF, 97KB]
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
