A Site Ifistory
Building 25 operated as a dry cleaning facility beginning in the 1940s. Five 750-gallon USTs
were installed on the north side of the building to store dry cleaning fluids. Initially,VarsolTM
was used in dry cleaning operations at Building 25. Because of flammability concerns,the use of
Varsol was discontinued in the 1970s and it was replaced with tetrachloroethene (PCE). The
PCE was stored in one 150-gallon aboveground storage tank (AST) adjacent to the north wall of
Building 25,in the same vicinity as the USTs. PCE was reportedly stored in the AST from the
1970s until 1995. During this time,facility employees have reported that spent PCE was
disposed of in floor drains that discharged to the sanitary sewer that serviced the building.
The USTs and AST were removed in November 1995. The dry cleaning operations ceased in
January 2004,and the building was demolished in August 2004.The site is currently an asphalt
parking lot that is located in a developed area of the Base. It is surrounded by buildings,
parking lots, streets, and sidewalks (Figures 1 and 2).
Investigation and remediation activities conducted at Site 88 include:
• Focused Remedial Investigation,1997
• Free Phase DNAPL Recovery, 1998: Conducted north of Building 25
• Partitioning Inter-well Tracer Test (PITT), 1998: Conducted adjacent to the north wall of
Building 25
• Surfactant-Enhanced Aquifer Remediation(SEAR), 1998-1999: Conducted adjacent to the
north wall of Building 25
• Reductive Anaerobic In-Situ Treatment Technology (RABITT),2001: Conducted at
monitoring wells IR88-MW05 and IR88-MW05IW,approximately 200 ft northwest of the
test area
• Shallow soil mixing with clay-zero valent iron,2005: Conducted north of Building 25
B. Hydrogeologic Description
General Regional Geologic and Hydrogeologic Framework
Southeastern North Carolina and Marine Corps Base Camp Lejeune (MCB CamLej) are within
the Tidewater region of the Atlantic Coastal Plain physiographic province. The MCB CamLej
area is underlain by an eastward thickening wedge of marine and non-marine sediments
ranging in age from early Cretaceous to Holocene. This wedge of sediment begins at the Fall
Line (western boundary of Atlantic Coastal Plain physiographic province) and dips
southeastward towards the coast. Along the coastline, several thousands of feet of interlayered,
unconsolidated sediment are present,consisting of gravel, sand, silt,clay deposits,calcareous
clays,shell beds,sandstone and limestone that was deposited over pre-Cretaceous crystalline
basement rock. Minor amounts of detrital carbonate shells, and secondary minerals such as
glauconite, siderite, and chlorite, often distinguish these sedimentary units.
Sedimentation and deposition within the Coastal Plain is controlled by fluctuations in sea level
on a subsiding continental margin in marine and near-shore environments (Winner and Coble,
1989). Confining units associated with specific aquifers within the Coastal Plain region are
composed of less permeable beds of clay and silt.Within the MCB CamLej area,approximately
1,500 ft of sediment overlies the basement rock. These sediments contain seven aquifers and

their associated confining units,and include the surficial, Castle Hayne,Beaufort,Peedee,Black
Creek, and Upper and Lower Cape Fear aquifers (Cardinell,Berg,and Lloyd,1993).
The lithology of the injection area consists of alternating fine grained silty sand and sand to
approximately 20 ft bgs,which are underlain by a more dense silty clay and clay layer
approximately 7 to 12 feet thick to a depth of approximately 30 ft bgs. Below this unit are
alternating layers of silty sand and sand. The sands become more dominate with depth and
fewer fines are present,generally between 40 to 60 ft bgs. A geologic cross-section within the
vicinity of the injection area is presented on Figure 2.
Site Specific Hydrogeology
The hydrogeologic setting at Site 88 is that of a two aquifer system,the surficial aquifer and the
Castle Hayne Aquifer,with the two aquifers typically separated by a low permeability clayey
silt aquitard (Duke,1999). This low permeability unit is present under former Building 25 in the
injection area, and is discontinuous to the west of former Building 25.
In November 2009, depth-to-water measurements were taken across Site 88. In the vicinity of
the injection area,the water table was found to occur from 7.25 to 10.10 ft bgs. The depth to
water in monitoring wells screened within the upper portion of the Castle Hayne Aquifer in the
vicinity of the test area,ranged from 14.46 to 15.62 ft bgs.
The potentiometric surface of the surficial aquifer and upper portion of the Castle Hayne
aquifer as measured in November 2009 are depicted on Figures 3 and 4,respectively. Shallow
groundwater flow in the injection area is to the southwest,with a horizontal hydraulic gradient
of approximately 0.002 ft/ft. Groundwater flow in the upper portion of the Castle Hayne
aquifer is generally to the west,with an approximate horizontal hydraulic gradient in the
vicinity of the injection area of 0.0004 ft/ft.
Aquifer testing was conducted in December 2009.A pneumatic slug test method was employed
through DPT-installed steel rod piezometers at three locations across the injection area. A
groundwater sampler equipped with a screen was installed in each boring to the terminating
depth of the testing interval. The drill rods were then pulled up to expose two feet of the screen
and conduct the slug test.
Hydraulic conductivity was calculated using the Hvorslev method. The hydraulic conductivity
values calculated at each slug test location are summarized below in Table 1.

Ingestion: Phosphates are slowly and incompletely absorbed when ingested, and seldom result in systemic
effects. However, such effects have occurred. May cause gastrointestinal tract irritation with nausea, vomiting,
and diarrhea. May affect behavior/central nervous system/peripherial nervous system (somnolence, convulsions,
lethargy, flaccid paralysis), urinary system (kidneys- renal failure, acute tubular necrosis). It may also cause heart
disturbances (fall in blood pressure, slow pulse) and blood chemistry effects (reduction of serum level of calcium).
The toxicity of phosphates is because of their ability to sequester calcium. Systemic metabolic acidosis may
result as this material is believed to be hydrolyzed to ortho phosphates when ingested (before absorption). Tetany
may also occur as a result of reduction in serum level of ionic calcium.

Section 12 Ecological Information
ENTRY TO THE ENVIRONMENT
Potassium permanganate has a low estimated lifetime in the environment,being readily converted by oxidizable
materials to insoluble Mn02.
BIOCONCENTRATION POTENTIAL
In non-reducing and non-acidic environments,Mn02 is insoluble and has a very low bioaccumulative potential.
AQUATIC TOXICITY
The toxicity data for Potassium permanganate is given below:
Rainbow trout,96 hour LC50: 1.8 mg/L
Bluegill sunfish,96 hour LC50: 2.3 mg/L
Milk fish Chanos Chanos /96 hour LC50: >1.4m 1
Section 13 Disposal Considerations
Offer surplus and non-recyclable product or solutions to a licensed disposal company.
Reduce RemOx®S ISCO Reagent in aqueous solutions with sodium thiosulfate,a bisulfite or ferrous salt solution.
The bisulfate or ferrous salt may require some dilute sulfuric acid(10%w/w)to promote reduction. Neutralize with
sodium carbonate to neutral pH,if acid was used. Decant or filter and deposit sludge in approved landfill. Where
permitted,the sludge may be drained into sewer with large quantities of water. Contact Carus Corporation for
additional recommendations.
Packaging materials must be triple rinsed to remove all RemOx®S ISCO Reagent prior to re-cycling or disposal.
