Foreword
The U.S. Environmental Protection Agency is charged by Congress with
protecting the Nation's land, air, and water resources. Under a mandate of national
environmental laws, the Agency strives to formulate and implement actions leading
to a compatible balance between human activities and the ability of natural systems
to support and nurture life. To meet these mandates, EPA's research program is
providing data and technical support for solving environmental problems today and
building a science knowledge base necessary to manage our ecological resources
wisely, understand how pollutants affect our health, and prevent or reduce environ-
mental risks in the future.
The National Risk Management Research Laboratory (NRMRL) is the Agency's
center for investigation of technological and management approaches for reducing
risks from threats to human health and the environment. The focus of the
Laboratory's research program is on methods for the prevention and control of
pollution to air, land, water, and subsurface resources; protection of water quality in
public water systems; remediation of contaminated sites and ground water; and
prevention and control of indoor air pollution. The goal of this research effort is to
catalyze development and implementation of innovative, cost-effective environ-
mental technologies; develop scientific and engineering information needed by
EPA to support regulatory and policy decisions; and provide technical support and
information transfer to ensure effective implementation of environmental regula-
tions and strategies.
Environmental scientists are generally familiar with the concept of barriers for
restricting the movement of contaminant plumes in ground water. Such barriers are
typically constructed of highly impermeable emplacements of materials such as
grouts, slurries, or sheet pilings to form a subsurface "wall." The goal of such
installations is to eliminate the possibility that a contaminant plume can move
toward and endanger sensitive receptors such as drinking water wells or discharge
into surface waters. Permeable reactive barrier walls reverse this concept of
subsurface barriers. Rather than serving to constrain plume migration, permeable
reactive barriers (PRBs) are designed as preferential conduits for the contaminated
ground water flow. A permeable reactive subsurface barrier is an emplacement of
reactive materials where a contaminant plume must move through it as it flows,
typically under natural gradient, and treated water exits on the other side. The
purpose of this document is to provide detailed design, installation and perfor-
mance monitoring data on a full-scale PRB application which successfully remediated
a mixed waste (chromate and chlorinated organic compounds) ground-water
plume. It was also the first full-scale installation of this technology to use a trencher
to install a continuous reactive wall to intercept a contaminant plume. The informa-
tion will be of use to stakeholders such as implementors, state and federal
regulators, Native American tribes, consultants, contractors, and all other inter-
ested parties. There currently is no other site which has used this innovative
technology and reported on its performance to the extent detailed in this report. It
is hoped that this will prove to be a very valuable technical resource for all parties
with interest in the implementation of this innovative, passive, remedial technology.

Abstract
A 46 meter long, 7.3 meter deep and 0.6 meter wide reactive barrier was installed at the U.S. Coast Guard
Support Center (USCG) in Elizabeth City, North Carolina, in June 1996. The reactive barrier was designed to
remediate a hexavalent chromium [Cr(VI)] groundwater plume, in addition to treating portions of a larger and not yet
fully characterized trichloroethylene (TCE) groundwater plume at the site. The barrier is composed of Peerless Metal
and Abrasives of Detroit, Michigan (Peerless™) granular iron and removes Cr(VI) and TCE from the groundwater via
processes of reduction and precipitation, and reductive-dechlorination, respectively.
In addition to nine large-screen compliance wells, a monitoring network of approximately 150 small-screen
sampling points was installed in November 1996 to provide detailed information on changes in porewater
geochemistry through the barrier. This network was sampled seven times between November 1996 and December
1998 at 3 to 6 month intervals: November 1996, February 1997, June 1997, September 1997, March 1998, June
1998 and December 1998.
Eh values decline from background values between 100 and 500 mV (vs. Standard Hydrogen Electrode, SHE)
to values as low as -580 mV SHE within the barrier. Groundwater pH values rise from background values between
6 and 8 to values as high as 11.74 within the barrier. These extreme Eh and pH conditions within the barrier have a
significant impact on the groundwater geochemistry. Concentrations of redox sensitive species such as sulphate
(SO4) and nitrate (NO3) decline from background values of up to 140 mg/Land 5 mg/Lto less than 20 mg/Land 0.05
mg/L, respectively. The decline of concentrations of Ca, Mg, Mn and alkalinity within the barrier may be the result of
Ca, Mg, Mn carbonate mineral precipitation. Geochemical calculations indicate that the water within the barrier
becomes supersaturated with respect to calcite [CaCO3], dolomite [CaMg(CO3)2] and rhodochrosite (MnCO3).
Low Eh and high pH values indicate that conditions are suitable for the reduction of Cr(VI), the precipitation of
Cr(lll) oxyhydroxides and the reductive-dechlorination of TCE within the barrier. Sampling results indicate that
upgradient concentrations of up to 5.1 mg/L Cr are consistently reduced to less than the maximum contaminant level
(MCL) of <0.05 mg/L within the zero valent iron barrier. In addition, the upgradient concentration of TCE (up to
5,652 u,g/L) is being reduced to close to or less than the maximum contaminant level (5 u,g/L TCE) within the
permeable barrier. Cr(VI) concentrations of less than the MCL value were consistently maintained downgradient of
the barrier. TCE and cis-1,2DCE (cDCE) concentrations of less than MCL values were maintained downgradient of
the barrier for most of the sampling sessions.
High TCE concentrations (> MCL) were regularly measured in the deepest (7 m) downgradient monitoring points
and in two downgradient compliance wells, one located at the western extent of the barrier and one located beneath
the barrier. Due to the limited size of the barrier, this part of the TCE plume was not intercepted by the barrier. In the
February and June 1997 sessions, TCE breakthrough at 17 and 6.8 u,g/L (respectively) was observed downgradient
of the barrier at one location, suggesting the presence of a zone of lower granular iron density or thickness. Although
there is localized breakthrough of TCE contaminated water, the results suggest that TCE and Cr(VI) contaminated
water that flows through the barrier is successfully treated to MCL values.
Vinyl chloride (VC) is also treated as the groundwater flows through the barrier. Occasionally VC concentrations
downgradient of the barrier concentrations exceed the MCL (2u,g/L). This breakthrough of VC may result from
inadequate residence time within the barrier, possibly due to higher than anticipated groundwater velocities within
the barrier, or less iron thickness in the barrier than the design criteria.

Introduction
A permeable in situ subsurface reactive barrier was installed in June 1996, at the U.S. Coast Guard support center located
near Elizabeth City, NC (Figure 1), to treat ground water contaminated by Cr(VI) and TCE (Bennett, 1997; Blowes etal.,
2000). The primary goal of the barrier was to remediate a 35 m wide and 6.5 m deep Cr(VI) plume which extends northward
from an old chrome plating shop towards the Pasquotank River (Figure 2). In addition to remediating the Cr(VI) plume, the
barrier is intended to treat portions of a larger overlapping TCE plume. Cr concentrations in excess of 10 mg/L and TCE
concentrations in excess of 19,200 ug/L have been detected in the shallow aquifer since 1991 (Puls et al., 1994; Parsons
Engineering Science, 1993,1994,1995,1997). These concentrations are orders of magnitude greater than the MCL for
these contaminants (0.05 mg/L Cr and 5 ug/L TCE).
The heterogeneous surficial aquifer at the site is composed of layers of fine sand mixed with varying amounts of silty clay,
which range between less than 0.3 m and greater than 3 m thick (Puls etal., 1994; Bennett, 1997). The aquifer is underlain
at approximately 20 m depth by dense clay of the Yorktown confining unit. The ground-water flow direction varies between
approximately N30°E and N10°W, with an average horizontal hydraulic gradient of between 0.0011 and 0.0033. Previous
studies provide a more detailed description of site geology and history (Parsons Engineering Science, 1993,1995,1997;
Puls etal., 1995; Bennett, 1997).
The barrier is a permeable subsurface wall composed of granular iron, installed in a 46 mlong, 7.3 m deep and 0.6 mwide
trench oriented perpendicular to the direction of ground-water flow (Blowes etal., 2000). The mass of Peerless™ granular
iron deposited into the trench (280 tons) was less than the design estimate of 450 tons. Assuming the iron fills the trench
completely, the calculated average emplaced density is 1.69 g/cm3. This emplacement density is lower than the value
determined for laboratory column tests, which were the basis of the barrier design (Blowes et al., 2000). The higher
laboratory-measured bulk density of 2.72 g/cm3, suggests that the in situ porosity of the emplaced iron (porosity^ = 0.62)
is greater than observed in the laboratory (n = 0.43). Alternatively, the lower mass of iron deposited in the trench suggests
that the granular iron may not occupy the entire volume of the trench. The physical properties of the granular iron,
calculated from previous laboratory column experiments (Bennett, 1997; Blowes etal., 2000), are shown in Table 1.
The granular iron reduces Cr(VI) and reductively-dechlorinates TCE in the ground waterthat flows through the barrier. At an
emplaced density of 2.72 g/cm3, the 60 cm wide barrier was calculated to provide sufficient residence time to remove
Cr(VI) from the ground water and degrade TCE and chlorinated degradation products that are intercepted by the barrier to
less than MCL values (Bennett, 1997; Blowes etal., 2000). Patents held by the University of Waterloo coverthe removal
of dissolved metals from ground water through the in situ precipitation of harmless, insoluble reduced metal phases in a
permeable reactive mixture placed in the path of the contaminated ground water (U.S. Patents 5,362,394 and 5,514,279).
A patent held by the University of Waterloo covers the in situ removal of dissolved halogenated organic contaminants from
water using zero valent iron installed in the pathway of the contaminated ground water (U.S. Patent 5,266,213).
The goal of this study was to determine changes in ground-water chemistry as the ground water flows through the reactive
barrier and to assess the effectiveness of the reactive barrier in reducing Cr(VI), TCE and degradation product
concentrations to less than their MCL values. Nine 10 ft (3.05 m) screened compliance wells were installed in the vicinity
of the barrier for long term monitoring of ground-water quality and for regulatory compliance. Five of these wells were
installed downgradient of the barrierto determine whether ground water directly downgradient, on either side of and beneath
the barrier meets the MCL values. A detailed monitoring network composed of three rows or transects of multilevel
samplers was also installed across the reactive barrier in November 1996 (Figure 3). This network was installed for
research purposes to provide a detailed description of ground-water geochemistry between the watertable and the bottom
of the barrier. The piezometer network was sampled seven times between November 1996 and December 1998, at 3 to 6
month intervals after barrier installation: November 1996, February 1997, June 1997, September 1997, March 1998, June
1998 and December 1998. Single well response tests were performed to assess the hydraulic conductivity within the
vicinity of the barrier. These results were used in conjunction with two-dimensional (2D) reactive-transport modeling to
assess the distribution and trends of ground-water contaminants and constituents. Ground-water samples were collected
and analyzed to determine the concentrations of the target contaminants Cr(VI), TCE, cDCE and VC. Ground-water

samples were also collected to define the overall ground-water geochemistry. Water chemistry data were interpreted with
the assistance ofthegeochemicalspeciation computer program, MINTEQA2 (Allison etal., 1990).
Objectives
The goals of the present study are to evaluate the in-situ hydraulic properties of the barrier and to determine if design
parameters were met. The collected data will provide evidence of the portion of the contaminant plume intercepted by the
barrier. Ground-water sampling several times a year, for several years will be used to determine the degree of removal of
the target contaminants TCE, cDCE, VC and Cr(VI) from the water, and for evaluating the long-term performance of the
barrier at removing the target contaminants.
Background
Reactive Barriers
Permeable in situ subsurface reactive barriers are a promising new technology that can be applied to treat ground water
contaminated by chromium (Blowes and Ptacek, 1992; Blowes etal., 1995a, 1995c, 1997; Puls etal., 1995), halogenated
organics (Gillhamand O'Hannesin, 1992, 1994; O'Hannesin, 1993), gasoline derivatives (Bianchi-Mosquera etal., 1994),
dissolved nutrients (Robertson and Cherry, 1995; Baker et al., 1996) and acid minedrainage (Blowes etal., 1995b; Benner
etal., 1 997; Waybrant etal., 1998; Benner et al., 1999). These barriers are composed of a permeable reactive material that
reacts with the contaminant in the ground water, reducing its concentration by physical or chemical processes. Processes
that can reduce the aqueous concentration of a ground-water constituent include adsorption, oxidation, reduction,
precipitation, chemical transformation or a combination of these processes. These subsurface reactive barriers are
installed into the flowpath of the contaminated ground-water plumes. The contaminated ground water is passively
remediated as it flows through the reactive barrier.
Cr(VI) Reduction
One of the principal contaminants at the U.S. Coast Guard Support Center (USCG), Elizabeth City, is Cr(VI). Cr(VI)
undergoes little adsorption or retardation in the saturated sediments at the Elizabeth City site and is found at concentra-
tions up to 10 mg/L (Puls et al., 1994). These Cr(VI) concentrations are significantly greater than the MCL value of
0.05 mg/L.
The approach to removing the Cr(VI) from the ground water at the site is to reduce Cr(VI) to Cr(lll) using zero-valent iron,
Fe°, as the reductant (eqn. 1).
8H+ + CrO42- + Fe° -» Fe3+ + Cr3+ + 4H2O (1)
The reduction of Cr(VI) by Fe° exhibit half-order kinetics with respect to Cr(VI) and H+ and is dependent on the surface-area
of Fe° (Gould, 1 982) as shown in eqn. 2
A (2)
where A is the surface area of zero-valent iron (cm2/L) and the surface-area normalized rate constant /(has a value of 5.45
x 10-5 L cm-2 min-1, or 3,270 L nr2 Ir1.
Laboratory experiments indicate that the reduction of Cr(VI) to Cr(lll) by granular iron is very rapid (Blowes and Ptacek,
1992; Powell et al., 1995; Blowes et al., 1997; Blowes et al., 2000). In treatability studies conducted using groundwater
from the Elizabeth City site, 12 mg/L Cr(VI) was reduced to less than the detection limit of 0.01 mg/L within tens of minutes
in batch experiments with Peerlessa granular iron (O'Hannesin etal., 1995; Blowes etal., 2000).
Once reduced by Fe°, Cr as Cr(lll) forms sparingly soluble hydroxides in water (eqn. 3) which have a minimum solubility
between pH 7 and 10. Underthese conditions, sparingly soluble Cr(lll) hydroxide or mixed Fe(lll)-Cr(lll) hydroxides may
precipitate (Eary and Rai, 1988; Schwertmann, 1989; Puls etal., 1994; Powell etal., 1995; Blowes etal., 1997; Blowes et
al., 2000) limiting dissolved Cr(lll) concentrations to less than the MCL value (Rai etal., 1 987; Sass and Rai, 1987; Blowes
etal., 1997).
(x) Cr 3+ + (1 -x) Fe3+ + 3H2O <^» (CrxFe1 x)(OH)3 + 3H+ (3)
The reduction ofCr(VI) by granular iron has also been demonstrated in small-scale field experiments (Puls etal., 1995) to
rapidly remove Crfrom contaminated ground water.
-------
TCE Reductive-Dechlorination
The other principal contaminant at the USCG site is TCE. The reductive-dechlorination of chlorinated aliphatics, such as
TCE, by Fe° is thermodynamically favored (Vogel et al., 1987). The reductive-dechlorination of TCE by Fe° to non-toxic
hydrocarbon end products occurs by both reductive p-elimination and sequential hydrogenolysis (Roberts et al., 1996;
Arnold and Roberts, 1997). The sequential hydrogenolysis pathway results in the production of toxic chlorinated
intermediates, such as cis-dichloroethylene (cDCE) and vinyl chloride (VC) (Figure 4). However, less than 10-20% of the
TCE mass degrades via this pathway producing cDCE and VC byproducts (Orth and Gillham, 1996), and these byproducts
are themselves reductively-dechlorinated by Fe°. The major end products of reductive-chlorination of TCE are ethene and
ethane. Ethene, ethane and lower concentrations of methane, propene, propane, 1-butene and butane end products have
been observed in previous laboratory experiments with granular iron (Orth and Gillham, 1996).
The reductive-dechlorination of TCE, cDCE and VC fits a pseudo first-order reaction mechanism. Johnson et al. (1996)
describe a pseudo first-order kinetic model forthe dehalogenation of various chlorinated hydrocarbons by Fe°:
(4)
where ksa is the specific reaction rate constant normalized to the surface area of Fe° (L Ir1 nr2), as is the surface area of Fe°
(m2 g~1) and pm is the mass concentration of Fe° (g L1 of solution). In this case, [P\ represents the concentration of TCE,
cDCE or VC. Reaction rates for TCE, cDCE and VC with Peerless™ granular iron were calculated from previous column
experiments (Bennett, 1997; Blowes et al., 2000) and are shown in Table 2.
Iron Corrosion
In addition to Cr(VI), TCE, cDCE and VC, other oxidized species are present in the ground water at the Elizabeth City site.
These include dissolved O2, NO3 and SO4. These oxidized species are reduced at the surface of the granular iron through
corrosion reactions similar to those observed for Cr(VI) and TCE. The redox potentials for these oxidized constituents
decline in the order: O2> NO3>SO4. Reduction of all of these constituents by granular iron is thermodynamically favorable,
with the energy yield decreasing in the same order: O2 > NO3 > SO4. Generally, redox processes proceed sequentially from
the highest energy yield downwards (Appelo and Postma, 1994), suggesting that O2 will be removed or reduced first
(eqn. 5).
2 Fe° + 02 + 2 H20 <=> 2 Fe2+ + 4 OH- (5)
Nitrate is expected to be reduced next (eqn. 6). Laboratory experiments indicate that the reduction of NO3~ by zero-valent
iron is rapid (Rahman and Agrawal, 1997; Cheng et al., 1997). This reaction forms a nitrite, NO2~, intermediate and
ammonia, NH3, as the end product.
4 Fe° + N03- + 10 H+ <=> 4 Fe2+ + NH4+ + 3 H2O (6)
Sulfate should be reduced next (eqn. 7). This reaction has been found to be quite slow, unless bacterially or microbially
catalyzed.
4 Fe° + SO42- + 10 H+ <^» 4 Fe2+ + H2S + 4 H2O (7)
In the absence of oxygen, the corrosion of iron by water itself can occur (Reardon, 1995) (eqn. 8).
Fe° + 2 H2O <^> Fe2+ + 2 OH- + H2(g) (8)
These reactions result in a decrease in these oxidized constituents and net increase in pH and ferrous iron concentration.
Laboratory experiments indicate that the iron corrosion rate and equilibrium pH are a function of solution composition
(Reardon, 1995). Geochemical calculations suggest that the pH of ground-water solutions in the presence of iron can be
controlled by ferrous iron mineral phases, which include amakinite [Fe(OH)2] and siderite [FeCO3].

Methodology
Monitoring Network Install at! on
Nine compliance wells and a detailed monitoring network of multilevel samplers were installed in the vicinity of the reactive
barrier (Figure 5, Appendix A). The compliance wells are constructed of 5.05cm (2 in) schedule 40 PVC pipe, with 1.5 or
3 m screened sections. Immediately downgradient of the barrier, two compliance wells (MW47 and MW49) are screened
between 4.3 and 7.3 m below ground surface and one deep well (MW50) is screened between 7.3 and 9.1 m below ground
surface. Further downgradient of the barrier, one well (MW46) is located at the western extent of the barrier and screened
between 4.3 and 7.3 m below ground surface and the other (MW35D) is centrally located and screened between 16.1 and
19.1 m below ground surface. The other four compliance wells are screened between 4.3 and 7.3 m below ground surface
and are located upgradient of the barrier. These compliance wells were installed using a hollow stem auger, as described
by Parsons Engineering Science (1995).
The detailed monitoring network consists of two rows of multilevel sampling bundles (Transects 1 and 3) and one row of
well clusters (transect 2). The multilevel sampling bundles and well clusters were installed in transects, each aligned
perpendicular to the reactive barrier and parallel to ground-water flow direction (Figure 3). The three transects were installed
across the width of the barrier (Figure 3, 5). Each transect contains five multilevel sampler bundles. Within each transect,
one multilevel sampler was placed approximately 2 m upgradient of the reactive barrier and one was placed approximately
1.5 m downgradient. The remaining three sampling bundles were placed in the barrier, inside of a 1.25 m long by 0.64 m
wide and 0.5 to 0.7 m deep metal-sided roadbox.
Multilevel sampling bundles of two configurations were installed into transects 1 and 3. Three of the multilevel sampling
bundles in transects 1 and 3 (ML11, ML14 and ML15; ML31, ML34 and ML35) are composed often 0.32 cm I.D. (0.125 in)
Teflon™ sampling tubes attached with nylon ties to a 1.26 cm (0.5 in) schedule 80 PVC centerstock (Figure 6). Bundles
ML12, ML13, ML32 and ML33 used 0.95 cm I.D. by 1.27 cm O.D. (0.375 in by 0.5 in) polyethylene centerstock. The ends
of the Teflon™ sampling tubes are arranged at 50 cm intervals, from depths of 2 to 6.5 m along the centerstock. Each
sampling tube terminates with a 15 cm (6 in) slotted section which is screened with 0.02 cm (0.0083 in) opening NYTEX™
nylon mesh attached with stainless steel wire. The PVC centerstock also terminates with a 15 cm (6 in) long 0.025 cm
(0.01 in) slotted section placed at a depth of 7 meters below ground surface (Appendix A).
The well clusters in transect 2 are comprised of seven 1.26 cm I.D. (1/4 in) Schedule 80 PVC wells. These wells were
assembled from commercial flush-joint casing slotted over the bottom section 15 cm (6 in) with 0.025 cm (0.01 in) slots.
The wells in each cluster were placed with their slotted sections terminating at 50 cm intervals from approximately 7 meters
depth to 4 meters depth below ground surface.
Bundles orwell clusters located outside of the permeable iron barrierwere installed using a 6.9 cm (2% in) I.D. hollow stem
auger. Bundles located within the granular iron barrier, inside the roadboxes, were installed using 5 cm (2 in) E/Wflush joint
drive casing. The use of smaller diameter drive casing caused less disturbance within the vicinity of the granular iron
barrier.
Field Analysis
Samples from the multilevel bundle piezometers were collected according to a modified version of the Standard Operating
Procedure RSKSOP-152 (Appendix I). Appendix H lists the standard operating procedures used for analytical measure-
ments. Measurements of Cr(VI), ferrous iron [Fe(ll)], dissolved sulfide (S2~), dissolved O2 (DO), electrical conductivity,
temperature, pH, Eh, alkalinity and ground-water turbidity were made in the field. Cr(VI), Fe(ll) and S2~ were analyzed in the
field colorimetrically with a UV/VIS spectrophotometer (Hach® DR/2010). Cr(VI) was analyzed directly on the spectropho-
tometer using 1,5-diphenylcarbazide as the complexing agent (Standard Methods, 1992). Fe(ll) was analyzed directly by a
colorimetric method using 1,10-phenanthroline as the complexing agent (Standard Methods, 1992). Dissolved sulfide was
determined colorimetrically using the methylene blue method (Standard Methods, 1992). Dissolved O2 measurements were
made using a CHEMets® colorimetric test kit for DO, which utilizes a rhodazine-D colorimetric technique (White et al.,
1990). Ground water electrical conductivity and temperature measurements were conducted on freshly pumped water
using an ORION® Model 128 conductivity probe and meter. The Eh and pH of freshly pumped ground water were measured
in a sealed flow-through cell using platinum redox and glass-bulb pH electrodes (ORION® 9678BN combination redox
electrode; ORION® Ross 815600 combination pH electrode). A constant-temperature water bath was used to maintain the
flow cell at ground-watertemperatures during pH and Eh measurements. The pH electrode and meter (Fisher Model 955
pH/mV meter) were calibrated at ground-watertemperatures using pH 4 and 7 or 7 and 10 buffer solutions at the start of the
day and between samples. The stability of the Eh meter and electrode were checked with Zobell solution (Zobell, 1946;
Nordstrom, 1977) and Light solution (Light, 1972) between samples. Alkalinity measurements were made by titrating
freshly filtered ground-water samples with standardized H2SO4 acid using a Hach® Digital Titratorand bromocresol green-
methyl red indicator. The turbidity of unfiltered ground water was determined with a Hach® turbidimeter (Model 21 OOP).
Where appropriate, field measurements were later corrected fortemperature.
-------
Sampling, Storage and Analysis
Ground-water sampling was conducted by University of Waterloo personnel at bundles located in transects 1 and 3.
Personnel from the R.S. Kerr Environmental Research Laboratory, U.S. EPA and from ManTech Environmental Research
Services Corp., Ada, Oklahoma, sampled bundles located in transect 2 in addition to the compliance wells at the site.
Detailed sampling included the collection of organic and inorganic samples, pH and Eh data, alkalinity, Cr(VI), Fe(ll) and
dissolved oxygen concentrations, ground-water electrical conductivity and turbidity. Detailed sampling was conducted at
even-numbered points in transects 1 and 3 and at all points in transect 2. At the odd-numbered points in transects 1 and 3,
all parameters except pH and Eh were collected. The following procedure and equipment description is forthe analysis and
collection of samples in transects 1 and 3. The procedures used by the EPA and ManTech for transect 2 were mostly
similar, except that a dissolved oxygen probe was used to determine DO concentrations.
Stainless steel sampling manifolds (Figure 7) were used to fill two 40 ml volatile organic analysis (VOA) glass vials and a
60 ml glass serum vial, for analysis of dissolved gases and volatile organic compounds (VOC). These manifolds,
designed and constructed at the University of Waterloo, prevent exposure of volatile organic ground-water samples to the
air and pump tubing, minimizing volatilization and adsorption. The manifold was placed upstream of a peristaltic pump
(Masterflex® Model 7533-20). Between 1.5 and 2 purge volumes of ground water (225-300 ml) were passed through the
manifold prior to collection of the samples. After the turbidity had been recorded, ground-water samples for analysis of
volatile organic parameters were collected. The samples were collected within the next 2 manifold purge volumes
(~300 ml) at flowrates of 100 to 200 mL/min, using the peristaltic pump, regardless of the turbidity of the ground water. In
most cases, purging, combined with the slow pumping rate resulted in lowwaterturbidity (<20 ntu; Nephelometric Turbidity
Units). Upon collection, the VOA and gas/VOC samples were preserved with one drop of concentrated H2SO4 and were
placed into coolers with ice until analysis. Between samples, the manifolds and pump lines were flushed with Alconox™
solution (~150 ml), followed by about 0.5 L of deionized water. All organic and inorganic contaminant samples were
submitted for analysis at ManTech Environmental Research Services Corp by the ManTech personnel. A discussion of the
quality assurance/quality control (QA/QC) results for field blanks, duplicates and trip blanks collected during the sampling
sessions is in included in Appendix J.
For each sampling session, at one point in each bundle, the sampling manifold was monitored for cross-contamination
effects. These field-blank samples consisted of deionized water pumped through the manifold immediately after being
flushed (using the normal field sampling routine) with Alconox™ solution and deionized water. At least one complete set of
duplicate samples (VOA and gases) was collected for each bundle, preserved according to the description above. Two
sets of trip blanks, originating from the EPA and the University of Waterloo research groups, were prepared for each
sampling session. Additional samples were collected from transects 1 and 3 for VOC analysis at the University of Waterloo
for comparison. Samples for analysis at the University of Waterloo were collected at even numbered points in transect 3,
where the VOC concentrations were higher, and one organic sample was collected from each bundle piezometer along
transect 1.
VOA vials were sampled automatically for analysis using a PTA-30 carousel type autosampler connected to a Tekmar LSC
2000 sample concentrator. Desorbed analytes were then transferred to a Hewlet-Packard Model 5890 gas chromatograph
(GC), where separated analytes were detected by a Flame lonization Detector (FID). Dissolved gases including ethene,
ethane and methane were analyzed by GC and FID (Kampbell etal., 1991). Refer to Appendix H forthe list of operating
procedures used forthe analysis of dissolved VOCs in the water.
After the ground water was sampled for organic parameters, samples were collected for the analysis of inorganic
parameters. Measurements of pH, Eh and carbonate alkalinity were made immediately before collecting water for cation
and anion analysis. The electrical conductivity of the unfiltered sample water was measured periodically as pH and Eh were
being measured. Temperature measurements were generally made after a bundle was completely sampled or during
purging. Cation and anion samples were collected downstream from the peristaltic pump (Masterflex® Model 7533-20), at
flowrates of 50 to 100 mL/min, after the turbidity had been recorded. Both filtered and unfiltered samples were collected for
cation analysis and were acidified to pH 1 with concentrated nitric (HNO3) acid. Filtered samples were passed through
disposable 0.45 urn Gelman™ Aquaprep filters after allowing a 100 ml purge volume to pass. Additional sets of unfiltered
samples were collected at each sampling point for comparative cation analysis by personnel from the R.S. Kerr
Environmental Research Laboratory, U.S. EPA. Total metal content was determined by ICP on an Atomcomp 975 system.
Refer to Appendix H forthe list of operating procedures used forthe analysis of dissolved cations in the water. Samples
that appeared turbid (generally greater than 75 ntu) were filtered prior to analysis for Cr(VI) and Fe(ll) on the Hach®
spectrophotometer.
Samples collected for anion analysis were unfiltered and not acidified. NO2 and NO3 concentrations were determined
colorimetrically following hydrazine reduction (Kamphake etal., 1967). Cl and SO4 concentrations were determined using
the Waters capillary electrophoresis method. Unfiltered samples were also collected for total organic carbon (TOC)
analysis. These samples were preserved with one drop of concentrated H2SO4. Appendix H summarizes the operating
procedures used forthe analysis of dissolved anions in the water.
-------
Even numbered sample points were analyzed for Cr(VI), Fe(ll) and DO after the collection of samples for inorganic
parameters. Forthe odd numbered points, these measurements were made afterthe collection of the VOC samples. DO
values were determined on freshly pumped well water, while Fe(ll) and Cr(VI) were analyzed within 10 minutes of being
collected, unfiltered.
Between samples, the pump lines were flushed with Alconox™ solution (~150 ml), followed by about 0.5 Lof deionized
water. At least one complete set (cations, anions, total organic carbon) of duplicate samples and post-decontamination
samples was collected for each bundle. These samples were filtered and preserved according to the description above.
The post-decontamination samples were collected after flushing the pump lines with Alconox™ and deionized water. Two
sets of trip blanks, originating from the EPA and the University of Waterloo research groups, were prepared for each
sampling session.
In the February 1997 and December 1998 sampling sessions, unfiltered, unpreserved water was collected in transects 1
and 3 for the analysis of34S enrichment of dissolved SO4. These analyses were conducted at the University of Waterloo
Environmental Isotope Laboratory.
Ground Water Flow
The piezometer elevations were surveyed and water level measurements were made to determine hydraulic head
(Appendix A). These measurements were made in the 1.26 cm I.D. wells in transect 2 and in the center stocks of the
bundles in transect 1 and 3, but not in the 0.32 cm I.D. Teflon™ multilevel bundles due to equipment limitations. Field
measurements of hydraulic conductivity were calculated from single-well response tests for wells in transect 2 and for the
center stock points of bundles upgradient and downgradient of the barrier in transects 1 and 3. Water levels were lowered
to steady drawdown values below static level at constant pumping rates and were monitored as the water level recovered
(Appendix F). Hydraulic conductivity was then calculated using the constant-head or variable-head method of Hvorslev
(1951).
Methods of Interpretation
Reactive-Transport Modeling
Two-dimensional ground-water flow and reactive transport simulations were performed with the computer model FRAC3D.
FRAC3D is a three-dimensional (3D) finite-element reactive-transport model that has been previously used to simulate the
flow hydraulics of Funnel-and-Gate systems (Shikaze and Austrins, 1995; Shikaze et al., 1995) and reactive barriers
(Bennett, 1997; Blowes etal., 2000). Using calculated hydraulic conductivities in transect 2, ground-water flow simulations
were used to estimate possible ground-water velocity distributions and ground-water flow pathlines within the vicinity of the
barrier. In addition, reactive transport simulations of the decay of TCE, cDCE and VC were performed to determine the
granular iron zone thickness necessary to explain the observed breakthrough of VC in transect 2.
Geochemical Modeling
The geochemical speciation computer model MINTEQA2 was used to assist in the interpretation of trends observed in the
data. The database of the model was modified to be consistent with the database of WATEQ4F (Ball and Nordstrom,
1991). The solid phase amakinite, Fe(OH)2, was added to the database. The reaction, expressed using MINTEQA2
components, is shown in eqn. 9.
Fe2+ + 2 H2O - 2 H+ <^» Fe(OH)2(s) Log K = -13.31 (9)

Results and Discussion
Hydrogeology
Hydraulic conductivity values were calculated for all sampling points in transect 2 (Figure 8a). Duplicate bail tests were
also conducted and generally indicated 30% agreement between values fora given sampling point. Because of the small
diameter of the sampling tubes in transects 1 and 3, hydraulic conductivity testing in these transects could be conducted
on only the larger center stock points, which are the deepest points in the bundles.
Calculated hydraulic conductivity values within the aquifer vary from 1 m/day to 16 m/day (Appendix F1). These values,
calculated in 15cm long, 1.26 cm diameter screened wells, differ from those measured in previous tracer and pump tests,
which were conducted within 1.5 m long, 5.05 cm (2 in) diameter screened wells. In the earlier well-response tests,
calculated hydraulic conductivity values were between 0.1 and 4.8 m/day (Sabatini etal., 1997). The hydraulic conductivity
estimated from a previous tracer test was 26 m/day (Sabatini et al., 1997). The aquifer in the vicinity of the permeable
reactive barrier is heterogeneous, and is comprised of a series of layers. The thickness of these layers varies from 0.3 to
3 m. The hydraulic conductivity values calculated from the small well screens, installed in the vicinity of the permeable
barrier, are probably reasonable estimates for these layers. Slug tests, conducted in the 1.5 m long screened wells, may
yield hydraulic conductivity values which represent an average of many layers within the screened interval. The operational
hydraulic conductivity varies with the scale of the problem and with the scale of the measurement (Bradbury and Muldoon,
1989), suggesting that the field measurements should be conducted on the same scale as the field problem. Bradbury and
Muldoon (1989) indicate that slug tests may only provide representative hydraulic conductivity values for the volume of
material tested; i.e., on the order of m3 for slug tests. The hydraulic conductivity values calculated within this study
therefore may be representative for the small, approximately 4 m by 3 m, cross-sectional area occupied by the sampling
points of the well clusters in transect 2.
The positions of the upgradient and downgradient edges of the barrier are inferred from construction information (Blowes et
al., 2000), and from measurements made in the field after the barrier was installed. Hydraulic conductivities measured
within the inferred zone of granular iron vary from 0.01 to 196 m/day. The highest hydraulic conductivity values measured
exceed the laboratory measured hydraulic conductivity of 85 m/day. The high hydraulic conductivity values measured
within the granular iron zone may result from the lower mass of granular iron deposited into the trench and the
corresponding lower emplaced density. The barrier design called for the installation of 450 tons of granular iron into the
trench; 280 tons of iron were actually installed. Assuming that the granular iron filled the entire volume of the 46 m x 7.3 m
x 0.6 m trench, the minimum average emplacement density is 1.69 g/cm3. This value is 62% of the value determined in the
laboratory column experiments (2.72 g/cm3).
The wide range of hydraulic conductivity values measured in the barrier may be a result of the installation technique. Due
to the installation method, the exact location of the front and rear of the barrier, the nature of the aquifer-barrier contact is
not known. The distribution of hydraulic conductivity values in the vicinity of the barrier suggests the locally, the zone of
granular iron may be thinnerthan the design value of 60 cm. Low hydraulic conductivity values (< 0.2 m/day) are measured
between approximately 4 - 5 m and 6.5 - 7 m depth below ground surface, nearthe upgradient side of the barrier. These low
hydraulic conductivity zones may result from mixing and disturbance of granular iron and aquifer material orslumping of
aquifer material into the granular iron zone.
Two-dimensional simulations of ground-water flow were performed using hydraulic conductivity values similar to those
observed within transect 2. The model domain was 4 m by 3.7 m (Figure 8b) with a grid spacing varying between 0.02 and
0.1 m. The top and bottom boundaries were designated as no-flow boundaries. The upgradient and downgradient
boundaries were assigned constant head values, resulting in an average horizontal hydraulic gradient of 0.0033 across the
domain. The flow simulation results (Figure 8c) indicate a zone of preferential flow and higher ground-water velocities
between 4.5 to 6 m depth, upgradient of the barrier. This zone moves downward to 5.5 to 6.5 m depth immediately
upgradient of the barrier because of the presence of low hydraulic conductivity zones at a depth of 4 to 5 m. Ground-water
velocities within the barrier also increase, perhaps as a result of a funnelling effect produced by the low hydraulic
conductivity layers on the upgradient side of the barrier. Modeled ground-water velocities are calculated to approach 0.20
m/day within the barrier.
During several of the sampling sessions, the roadboxes in transects 1 and 2 were observed to fill with water from the
parking lot during rain events. The hydrogeological implications of this flooding have not been determined. Although the
hydrogeological response in the aquiferto these flooding events was not monitored, the spatial distribution of geochemical
parameters within the aquifer remained relatively uniform between sampling episodes. The Roadbox in transect 3 did not fill
with water during the rain events.
Conservative Ground Water Constituents
Sodium and chloride are anticipated to be relatively conservative under the geochemical conditions present at the site.
Between November 1996 and December 1998, only small variations in the Na and Cl concentration profiles are observed
-------
(Figure 9, Appendices D and E). The highest concentrations of Na and Cl coincide with the zones of highest concentrations
of Cr(VI) and dissolved organic contaminants.
Comparison of Na and Cl concentrations indicates a 1:1 molar stoichiometry. The Na:CI ratio is similar upgradient, within
and downgradient of the reactive barrier. The concentrations of these species do not change significantly in the vicinity of
the barrier or downgradient. These observations suggest that the granular iron of the barrier does not affect the transport of
Na and Cl. Na and Cl, therefore, can be used as conservative tracers, their vertical distribution indicating preferential
flowpaths and possible higher conductivity zones within each transect. There is some agreement between measured
hydraulic conductivity, the flow modeling results and the distribution of Na and Cl within transect 2. These results suggest
that there is a preferential flowpath between 4 and 6 m depth below surface.
Redox and pH Conditions
The Eh of untreated ground water entering the barrier is generally high, at between 400 to 500 mV at ground-water
temperatures (15-20°C) (Figures 10,11; Appendix B). The Eh decreases sharply, by several hundred mV, within the barrier
to between +50 and -600 mV, reflecting the removal of oxidized species including dissolved oxygen, nitrate, ferric iron, and
sulfate from water in the barrier. Both high and low Eh values are observed in the sampling bundles located just upgradient
of the front of the barrier in transect 1. This distribution suggests that the piezometer bundles ML12, ML22 and ML32 are
located at the leading edge of the barrier, where the distribution of granular iron is irregular. Within the barrier, Eh values in
transect 1 are generally several hundred mVlowerthan in the other two transects. Between November 1996 and December
1998, Eh values downgradient of the barrier decreased slightly. Within the barrier, no consistent change in Eh values was
evident between sampling episodes.
The measured pH of untreated ground water entering the barrier is slightly acidic, with pH values between 5.5 and 6.7 at
ground-water temperatures (Figures 12,13, Appendix B). The pH of water entering the barrier increases sharply to between
7.6 and 11. The increase in pH in the barrier is likely most attributable to the corrosion of iron (eqns. 5, 8). The pH within the
barrier in transect 3 is generally lowerthan in the othertwo transects, possibly reflecting different positions of the sampling
points relative to the upstream edge of the barrier. At the most downgradient bundle in each transect, pH values decrease
to between 6.5 and 9.4, suggesting that water with higher pH values generated in the barrier is being transported and
neutralized in the aquifer downgradient of the barrier. In general, ground-water Eh and pH values approach background
levels downgradient of the barrier.
Major Ions
Upgradient of the barrier, the dissolved iron concentration is highest between 2 and 4 m (up to 7.5 mg/L total Fe) below
surface. Dissolved iron is not detectable at greater depth (Figure 14,15; Appendix D). Total dissolved iron concentrations
(Fe) are occasionally higher than ferrous iron [Fe(ll)] concentrations. Underthe neutral to alkaline pH conditions that prevail
in the aquifer, dissolved Fe(lll) concentrations are expected to be negligible because of the low solubility of Fe(lll)
oxyhydroxide minerals. The higher concentrations of total dissolved iron may reflect differences between the methods
used to measure the total and ferrous iron concentrations. The colorimetric method used to measure Fe(ll) does not detect
iron bound to colloidal material. In contrast, the ground-water samples analyzed by ICP were preserved by acidification.
Acidifying the samples may have dissolved colloidally bound Fe(ll) and Fe(lll), resulting in higher measured total iron
concentrations.
The exposure of the ground waterto the atmosphere during sampling may have resulted in oxidation of Fe(ll)to Fe(lll), and
subsequently lower Fe(ll) concentrations. Hem (1982) suggests that the precipitation of ferric oxyhydroxide by oxygenation
of ferrous solutions is rapid at near neutral pH and increases by a factor of 100 for each unit increase in pH. In an effort to
minimize the possibility of this complication, samples at the field site were typically analyzed for Fe(ll) within 10 minutes
of being collected.
At shallow depths upgradient of the barrier, iron concentrations increase between the November 1996 and December 1998
sampling sessions. MINTEQA2 calculations suggest that, where Fe is measurable upgradient of the barrier, the ground
water is supersaturated with respect to ferrihydrite [Fe(OH)3] and goethite [FeOOH] (Figures 16-18, Appendix G).
Precipitation of these phases may limit Fe concentrations at shallow depths, upgradient of the barrier. Between 4 and 7 m
depth upgradient of the barrier, Fe concentrations are consistently near detection.
Iron Corrosion
Total iron concentrations increase from upgradient values of < 0.5 mg/L, to as much as 18 mg/L at the upgradient edge of
the barrier (Figures 14,15). The presence of high Fe concentrations in the bundles just upgradient of the barrier (bundle
ML12) suggests that granular iron may exist in front of the assumed position of the front of the barrier. This increase in
concentrations in the barrier is probably a result of the corrosion of the granular iron (eqn. 5, 8) and the removal of Cr(VI)
(eqn. 1). In transects 1 and 2 total iron concentrations decrease to less than 1 mg/L further downgradient in the barrier. In
transect 3, ground waterwith a total iron concentration of 0.1 to 4 mg/L persists across the width of the barrier. Total iron
reaches peak concentrations of 14 to 16 mg/L locally within transect 3.
-------
MDLforFeis lower forthe performance report. Total iron concentrations at the most downgradient bundle in each transect
(5th bundle position, ML x5, where x=1,2, 3; Figures 3, 5) range from the detection limit (0.002 mg/L) to 5 mg/L. The higher
concentrations (> 2 mg/L) in the most downgradient bundles are observed at depths less than 4 m. At these points, higher
Fe concentrations may result from the oxidation of mixtures of granular iron, entrained in the aquifer material, by infiltrating
surface water. The absence of higher Fe concentrations in the deeper points of the 5th bundle position suggest that Fe
released during the reduction of Cr(VI) is removed from the water before leaving the barrier, or in the aquifer sediments
between the barrier and the 5th bundle.
MINTEQA2 calculations suggest that the water within and downgradient of the barrier approaches equilibrium with respect
to ferrihydrite and is supersaturated with respect to goethite (Figure 16). These calculations assume a Fe concentration of
Fe=0.001 mg/L (/.e.,20% of the MDL) for samples containing Fe concentrations that are below analytical detection. It is
likely that precipitation of ferrihydrite, goethite or a mixed Cr-Fe oxyhydroxide limits Fe(lll) concentrations within the barrier.
In all cases, the Fe(lll) concentration is calculated from the total iron concentration based on the measured Eh of the water.
Samples from transect 3 (Figure 18) have the highest concentrations of Fe. The water in the barrier at transect 3 ranges
from slightly undersaturated to slightly supersaturated with respect to ferrihydrite (-1.4 < SI < 1.6, SI=Saturation Index) and
is supersaturated with respect to goethite. An analysis of the barrier materials using samples collected six months after
installation, confirmed the presence of goethite (Palmer, 1999). These results are consistent with laboratory experiments in
which Cr(VI) removal from the water with Fe° was attributed to the co-precipitation of Cr with goethite (Blowes etal., 1997;
Blowes etal., 2000), ora mixed Fe(lll)-Cr(lll) hydroxide solid (Puls etal., 1994; Powell etal., 1995 and Blowes etal., 1997).
Where dissolved iron concentrations within the barrier exceed the MDL (transects 2 and 3), MINTEQA2 calculations
suggest that the water approaches or attains equilibrium with respect to siderite and amakinite (Figures 19, 20).
Precipitation of these minerals may affect the pH and may limit Fe concentrations in the water as it passes through the
barrier. In areas where the Fe concentration is below the MDL, the Fe concentration was assumed to be 0.001 mg/L (i.e.,
20% of the minimum detection limit (MDL)). The saturation index values reported from these locations, therefore, are not
strictly representative of the aquifer/barrier conditions. Palmer (1999) confirmed the presence of amakinite, but did not
unequivocally identify siderite in material collected from the barrier six months after installation.
The observed increase in ferrous and total iron concentrations near the upstream edge of the barrier indicates that the
corrosion (eqn. 8) or oxidation of zero-valent iron (eqn. 7) is occurring. The oxidation of zero valent iron is coupled with the
reduction of oxidized species, such as DO, NO3,orSO4 (eqns. 5-7). The DO concentrations in the barrier and aquifer are
variable, but generally are low(< 1 mg/L; Figures 21-26). Upgradientofthe barrier, the highest concentrations of NO3 and
SO4 were measured between 4 and 6 m below the ground surface. Sulfate concentrations in the upgradient water vary by
40-80 mg/L between sampling sessions, with no trend overtime. Nitrate and SO4 concentrations decrease sharply as the
ground water enters the barrier. Nitrate concentrations of up to 8 mg/L in the upgradient zone decrease to below detectable
values (0.1 mg/L) within a few centimeters distance into each transect. Sulfate concentrations decrease more slowly with
distance into the barrier. Influent SO4 concentrations of up to 140 mg/L generally decline to detection limit values (0.1 mg/L)
before reaching the downgradient side of the barrier. The relative depletion of NO3 and SO4 in the barrier is consistent with
the thermodynamically predicted sequence, where the species with lower redox potential persist (eqns. 5-7).
Sulfate concentrations at locations within and downgradient of the barrier are similar in all sampling sessions. Nitrate and
SO4 remain at low concentrations downgradient of the barrier (Figures 21-26), suggesting that these compounds are being
mineralized or retained within the barrier. Underthe strongly reducing conditions present within the barrier, NO3 and SO4 are
thermodynamically unstable and may be reduced to ammonia and sulfide species. Determinations of the 34S/32S isotopic
ratio of dissolved sulfate-sulfur indicate that the dissolved sulfate of water samples collected from several locations within
and downgradient of the barrier in transect 3 is enriched in 34S relative to upgradient locations (Table 3). Enriched 34S
concentrations is indicative of bacterially mediated sulfate reduction (Thode, 1951). Within transect 1, there is no clear
evidence of 34S enrichment. In most parts of the barrier, SO4 concentrations were too low for sulfur isotopes to be quantified
on 1 liter samples.
Geochemical calculations conducted with MINTEQA2 suggest that the reduced forms for nitrogen and sulfur (NH3 and S2~
respectively) are the dominant aqueous forms under the measured pH and Eh conditions. Saturation index values for
ferrous monosulfide and mackinawite [FeS] were calculated using the measured pH, Eh, total iron and sulfate values and
allowing the field-measure redox potential to control the speciation of iron and sulfur. The results from the November 1996
sampling session suggest that the water is generally undersaturated with respect to ferrous monosulfide and mackinawite
within the barrier, although supersaturation is indicated at one location in transect 1 (Figure 27). In areas where Fe and SO4
are below detection, the Fe and SO4 concentrations specified forthe MINTEQA2 calculations were set at 0.001 mg/L (20%
MDL) and 0.01 mg/L (10% MDL) respectively. Mineralogical study of the barrier materials did not confirm the presence of
secondary sulfides (Palmer, 1999). The lack of detection of these phases may reflect the difficulty in detecting the small
mass that could have formed in the 6 month treatment period before analysis of the material. SI values forthe December
1998 data (Figure 27, Appendix G) suggest that the water is near equilibrium or is supersaturated with respect to
mackinawite at locations nearthe middle or downgradient side of the barrier in transects 1 and 2. These results suggest
-------
that the precipitation of these sulfide minerals or other less crystalline precursors within the reactive barrier is thermody-
namically favored.
The ground-water Eh declines from upgradient values of 100 to 500 mV SHE to less than -100 mV SHE within the barrier,
in all transects (Figures 10, 11). In transects 1 and 3, Eh values less than -500 mV SHE approach the lower limit of
thermodynamic stability for water. These strongly reducing conditions suggest that the reduction of water by Fe° may be
occurring. The reduction of water is a net acid consuming reaction, which increases the pH and releases H2 gas (eqns. 5,
8). The pH increases from between 5.5 and 7 upgradient of the barrier, to between 8.5 and 11 within the barrier (Figures 12,
13). Changes in the pH measurements made at individual sampling points between the first and last sampling sessions are
minimal.
The rate of iron corrosion in ground water has been estimated from hydrogen evolution rates (Reardon, 1995). Iron corrosion
rates of approximately 0.05 - 0.7 mmol Fe2+ (kg Fe)~1 day1 were reported. Assuming a residence time of 4 days within the
barrier and a calculated iron density of 3.9 kg Fe/L H2O, a maximum ferrous iron concentration of approximately 520 mg/L
is expected. The maximum observed concentration of 15 mg/LFe is significantly lower than the calculated concentration.
Reardon (1995) found that the iron-corrosion system reaches an invariant composition upon saturation with respect to iron
mineral phases, which included amakinite and siderite. The calculated pH of these invariant systems was in close
agreement with observed iron-corrosion experiments.
Cr(VI) Reduction
Upgradient of the barrier, the center of Cr plume mass is located between 4.5 and 5.5m below the ground surface (Figures
28,29). The margins of the plume, defined by the MCL value of 0.05 mg/L, are located between 4 and 7 m below the ground
surface. The highest Cr(VI) concentrations (2-4 mg/L) are observed upgradient of the barrier in transects 1 and 2. Cr(VI)
concentrations entering transect 3 are lower than in transects 1 and 2, with maximum values varying with time between 0.1
and 0.5 mg/L. Between November 1996 and December 1998, the concentrations and distribution Cr(VI) upgradient of the
barrier vary by 1 - 2 mg/L (Figures 30-32). The Cr plume extends beyond transect 1 to the east, but is fully intercepted on
west side of the barrier. The vertical extent of the Cr plume is fully intercepted by the barrier.
Total Cr and Cr(VI) determinations (Appendices B and D) indicate that Cr(VI) is the dominant valence of dissolved Cr in
ground water entering the barrier and that Cr(lll) concentrations in this water are low. In transects 2 and 3, Cr(VI)
concentrations decrease slightly priorto entering the barrier (Figures 31, 32). Where Cr concentrations are above detection
upgradient of the barrier, the ground water is slightly supersaturated with respect to amorphous Cr(OH)3 and is
undersaturated with respect to crystalline Cr(OH)3 (Figures 16-18). This early depletion of Cr(VI) suggests that some zero
valent iron may have been entrained in the sand adjacent to the barrier and that Cr(VI) reduction begins a few centimeters
in front of the assumed barrier position.
In each transect the Cr plume dips to a greater depth as it approaches the barrier. The change is most pronounced in
transect 2, where it enters the barrier at 6-7 m depth. Within a few centimeters (<10 cm) travel distance into the barrier,
Cr(VI) concentrations decline from upgradient values as high as 4 mg/L to less than 0.01 mg/L (Figures 30-32). Underthe
highly reducing conditions within the barrier, Eh values approach -600 mV SHE (Figures 10, 11). Thermodynamic
calculations suggest that Cr(lll) is the dominant valence state of Cr below an Eh of approximately 200 mVat pH 10.
Cr042- + 3 e- + 5 H+ => Cr(OH)3° + H2O Log K= 60.27 (10)
pe = 20.09-1.67 pH
The high pH conditions within the barrier favor the precipitation of sparingly soluble Cr(lll) hydroxide and mixed Cr(lll)-
Fe(lll) hydroxide phases. Analytical measurements confirm that the total Cr concentrations and therefore also the Cr(lll)
concentrations are near the Cr analytical detection limit (0.002 mg/L) within the barrier. Calculations conducted with
MINTEQA2 suggest that dissolved Cr(lll) concentrations of 0.01 mg/L Cr(lll) (i.e., 50% of the Cr(VI) MDL) within the barrier
would result in supersaturation of the waterwith respect to amorphous Cr(OH)3. The co-precipitation of Crwithin a mixed
Fe(lll)-Cr(lll) oxyhydroxide (e.g. CrxFe1 x(OH)3) would also result in the observed low Cr concentrations. The total dissolved
Cr concentration, and therefore dissolved Cr(VI) concentration, remains less than 0.01 mg/Ldowngradientofthe barrier in
all transects and all sampling sessions. There is no indication of a decline in effectiveness of the granular iron barrier at
removing Cr over the two and one half-year monitoring period (Table 4).
Unfiltered samples were analyzed for Cr(VI) in the field using a UV/VIS Hach DR/2010 spectrophotometer and
1,5-diphenylcarbazide complexing agent. This technique is specific for Cr(VI), whereas total Cr samples were analyzed in
the laboratory by ICP. Although the total Cr samples were filtered, the 0.45 urn filter may not exclude colloidal particles
which contain adsorbed Cr(VI) or possibly reduced Cr(lll) precipitates. Acidification of the ground-water samples as a
preservation technique may also release the colloidal Cr. As a result, the measured total Cr concentrations (i.e., including
colloidal Cr) may be higherthan the actual aqueous total Cr values. A comparison conducted during one sampling session
(March 1998) suggests that 0.45 urn filtered total Cr and unfiltered Cr(VI) concentrations are similar.

Reductive-dechlorination of Chlorinated Aliphatics
TCE, cDCE and VC
Upgradient of the barrier, the TCE plume occurs at two discrete depth intervals (Figures 33-38). The upper part of the plume
is 4 to 5 m below ground surface and is totally intercepted by the barrier. The deeper plume is present below 6 m depth, and
is not totally intercepted by the barrier. The highest TCE concentration (3,790 ug/L, December 1 998; Appendix C) is located
upgradient of the barrier in transect 2, in the lower plume. Maximum TCE concentrations within the upper plume are found
in the upgradient portion of transect 3 (680 to 2,000 u,g/L). The lowest influent TCE concentrations are located upgradient
of transect 1 (60 to 114 u,g/L). Between November 1996 and December 1998, there is no consistent increase or decrease
in TCE concentrations upgradient of the barrier (Table 4).
In addition to TCE, the ground-water upgradient of the barrier contains cDCE and VC. The cDCE (Figures 34, 37) and VC
(Figures 35, 38) plumes are located between 4 and 5 m below ground surface, with the highest concentrations
(170-286 u,g/L cDCE, 29-65 u,g/L VC) located upgradient of transects 2 and 3. Between November 1996 and December
1998, there is no consistent increase or decrease in cDCE or VC concentration upgradient of the barrier. cDCE and VC
were not detected in the lower plume, upgradient of the barrier (Table 4).
TCE, cDCE and VC distribution along transects 1 , 2 and 3 are shown in Figures 39 through 44. The upper TCE plume dips
slightly as it approaches the barrier. Ground-water flow and contaminant transport simulations (Figure 45) indicate that the
TCE plume moves downward due to the presence of the low hydraulic conductivity zones immediately upgradient of the
reactive barrier. In each transect the TCE concentration decreases to less than approximately 5 u,g/L within a few
centimeters travel distance into the barrier. The degree of TCE treatment in the barrier does not change significantly
between the first and last sampling sessions (Table 4). TCE concentrations remain less than 5 u,g/L downgradient of the
barrier in all sampling sessions.
The cDCE concentration decreases from a maximum value of 290 u,g/L upgradient of the barrier to less than 24 u,g/L within
a few centimeters travel distance in the barrier. Except for one measurement of 22 ug/L (February 1997; Table 4), cDCE
concentrations downgradient of the barrier are < 11 ug/L. These cDCE concentrations are less than the MCL value of
70
The maximum VC concentration upgradient from transects 2 and 3 varies from 32 to 65 u,g/L. These VC concentrations are
reduced within the barrierto less than 6 u,g/L. Generally, VC concentrations downgradient of the barrier are less than 5 u,g/L,
slightly greaterthan the MCL value of 2 ug/L, however, the concentrations vary from less than the MCL up to 9 ug/L. VC
concentrations of ~1 ug/L are common downgradient of transect 1 in the November 1996 and December 1998 sampling
sessions, although VC was not detected upgradient of the barrier during these periods. This VC is a product of TCE
degradation. The degree of removal VC does not vary significantly between sampling sessions.
In each transect, the distribution of TCE, cDCE and VC remains relatively constant between sampling sessions. However,
the maximum TCE concentration upgradient of transect 3 increases from approximately 400 ug/L to 2,000 ug/L between
November 1996 and February 1997 and then decreases to 670 ug/L in December 1998. Higher TCE, cDCE and VC
concentrations within and downgradient of the barrier in the February 1 997 sampling session are associated with these high
upgradient TCE concentrations. For example, downgradient of the barrier cDCE concentrations increase from 1 1 ug/L in
November 1996, to 23 ug/L in February 1997. This increase in the cDCE concentration downgradient of the barrier is
probably due to the increased TCE concentration entering the barrier in February 1 997. These cDCE concentrations remain
below the MCL of 70 ug/L, however.
A second, deeper TCE plume is located at > 6 m depth in transects 2 and 3 (Figures 36, 39-44). The concentrations of
cDCE and VC are not detected in the position of this deeper TCE plume. Maximum TCE concentrations of 5,652 ug/L were
measured within this deep plume at the front of the barrier (ML22-1, transect 2) in November 1996. During subsequent
sampling sessions, TCE concentrations at this position decreased, eventually to 242 u,g/L in December 1998 (Table 4).
These concentrations declined to less than 5 u,g/L downgradient within the barrier. In the November 1 996 and February
1 997 sampling sessions, TCE concentrations at the deepest point in the farthest downgradient bundle in transect 2 are at
high values, between 50 and 140 u,g/L (Figure 40). This observation suggests that part of the TCE plume extends below the
base of the barrier and is not treated. In subsequent sampling sessions, however, TCE at this point was below the MCL,
suggesting the direction of flow may vary periodically. cDCE concentrations exceeding MCL values were not detected in
these deepest monitoring points. In February 1997 and December 1998, VC concentrations (4-15 u,g/L) at these deep
monitoring points exceeded MCL values in transect 2.
Continued monitoring of the reactive barrier indicates that the barrier is reducing TCE and cDCE concentrations to less than
MCL values. The sampling results suggest that the granular iron has remained effective at removing the TCE and cDCE
overthe two and one-half year monitoring period. VC concentrations of up to 5 u,g/L are present downgradient of the barrier
and exceed the MCL value of 2 u,g/L. The breakthrough of VC at just above MCL values may result from inadequate
residence time within the barrier. The short residence time may result from a combination of factors including higherthan
11
-------
anticipated ground-water velocities within the barrier, reaction rates that are slower than measured in laboratory
experiments, and lower density of iron within the barrier. Lower iron densities may occur where the granular iron pinches out
orthins to less than the design value of 60 cm. In places, the iron emplacement density may also be less than the average
value. Increased ground-water velocities may result from the funnelling effects of low conductivity layers upgradient of the
barrier. Laboratory measurements indicated that the reductive-dechlorination rates are surface-area dependent and thus
are proportional to the density of granular iron within the barrier (Gillham and O'Hannesin, 1994). Because the emplaced
granular iron density is less than the laboratory-measured value, the reaction rates between the iron and volatile organic
contaminants within the barrier will be less than the laboratory-measured rates.
Reactive Transport Simulations
Three reactive transport simulations were performed with FRAC3D to assess the thickness of granular iron that would
explain the observed breakthrough of 5 ug/L VC (Bennett, 1997). The transport parameters used are shown in Table 5 and
the results from these simulations are shown in Table 6. Simulation 1 assumes that the emplaced iron density (2.72 g/cm3)
and reaction rates are the same as in the laboratory. Simulation 2 assumes that the granular iron occupies the entire
volume of the trench and therefore has a lower emplacement density of 1.69 g/cm3. Corresponding overall reaction rates
are only 62% of the laboratory-measured values because the surface area density of granular iron would be only 62% of the
laboratory-measured value. Simulation 3 has the same assumptions as simulation 2. However, the lower emplacement
density corresponds to a higher porosity, which is calculated to be 0.62. This higher porosity will result in lower ground-
water velocities within the barrier.
The reactive transport simulations indicate that the observed breakthrough of 5 u,g/L VC would occur if the width of the
granular iron zone were between 8 cm and 12 cm, depending on the emplaced density of granular iron. The observed
breakthrough of VC suggests that in places the barrier thickness may not meet the design criteria.
Dechlorination Products
The major end products of reductive-chlorination of TCE are ethene and ethane. Ethene, ethane and lower concentrations
of methane, propene, propane, 1 -butene and butane have been found to account for 70% of the TCE mass in iron column
experiments (Orth and Gillham, 1996). Ethene, ethane and methane are not detected upgradient of the barrier (Figures 46,
47). The concentrations of these dissolved gases increase within and downgradient of the barrier. The highest concentra-
tions are generally found in transects 2 and 3. Ethene concentrations increase from below detection (3 u,g/L) upgradient of
the barrier to as high as 44 u,g/L in the barrier (transect 2, November 1996), with downgradient concentrations ranging from
4 to 24 u,g/L. Ethane concentrations increase from below detection (2 u,g/L) upgradient of the barrierto as high as 59 u,g/L
within the barrier (transect 2, November 1996). Downgradient from the barrier, ethane concentrations up to 39 u,g/L are
observed. Methane concentrations increase from less than 1 u,g/L upgradient of the barrierto 31 u,g/L at the front of the
barrier. Between the November 1996 and December 1998 sampling sessions, the maximum concentrations of these gases
decreased by 50 to 75% (Figures 46, 47 Appendix C).
Compared in terms of molar concentrations, the maximum concentrations of 1.5 u,M ethene, 0.3 u,M ethane and 2 mM
methane are significantly greaterthan the maximum TCE concentration of 0.05 mM. A mass balance comparison of TCE,
cDCE and VC and methane, ethane and ethene concentrations indicates that these hydrocarbons can account for more
than 100% of the chlorinated organics present. Figures 48 and 49 indicate that the TOC content of the water increases
slightly within the barrier. The spatial correlation between these gases and the chlorinated organics is poor. As a result, a
mass balance for breakdown products cannot be conducted as these observations suggest that other sources are
generating organic carbon, increasing the TOC and releasing methane. Hydrocarbons have been produced in water/iron
batch and column systems in the absence of chlorinated aliphatic compounds. It has been hypothesized that these
hydrocarbons were formed by the reduction ofaqueousCO2byzero-valentiron (Hardy and Gillham, 1996). Alternatively,
the carbide carbon in iron has been suggested as a likely source for the production of background hydrocarbons (Deng et
al., 1997). A mass balance comparison of TCE, cDCE, VC and chloride ion is similarly inconclusive as upgradient Cl
concentrations are significantly larger, by a factor of 20 or more, than chlorinated organic concentrations.
Mineral Precipitation
Major cations within the ground water include Ca, Mg and Mn. The highest concentrations of these ions are observed
between 3 and 5 m below ground surface. The concentrations of these species decline in all transects as ground water
moves into the barrier (Figures 50-55; Appendix D and E). Ca concentrations decrease from as high as 40 mg/L upgradient
of the barrierto less than 5 mg/L within and downgradient of the barrier. Mg concentrations decrease from up to 17 mg/L to
less than 5 mg/L. Mn concentrations decrease from up to 3.3 mg/L to less than 0.1 mg/L. The concentration of Ca, Mg and
Mn remained consistent in all transects between samplings sessions.
Upgradient of the barrier alkalinity values range between 40 and 110 mg/L as CaCO3. Alkalinity values decrease
substantially within the barrier, to between 10 and 80 mg/L CaCO3 (Figures 56, 57; Appendix B). These lower alkalinity
12
-------
values extend downgradient of the barrier. Geochemical calculations indicate that the SI values of calcite [CaCO3],
aragonite [CaCO3], dolomite [CaMg(CO3)2], siderite, rhodochrosite [MnCO3] and magnesite [MgCO3] (Figures 58-63)
approach or exceed 0 within the barrier. The concentrations of dissolved Ca, Mg, Mn and alkalinity, therefore, may be
controlled by the precipitation of carbonate minerals, or more hydrated carbonate phases. Between November 1996 and
December 1998, alkalinity values throughout each transect varied without consistency.
The precipitation of carbonate, sulfide and hydroxide minerals within the barrier also can impact the performance of the
barrier, by altering the porosity and reactivity (available reactive surface) of the granular iron media. A decrease in porosity
will result in increased ground-water velocities within the barrier, with an associated reduction in available reactive surface
area. Secondary mineral precipitation may eventually lead to clogging of the barrier. Previous column studies using zero
valent iron have indicated uniform porosity losses throughout the column, which decline rapidly at first and then level off to
between 5-15%. This porosity change was attributed to the precipitation of Fe(OH)2 (amakinite) and the formation of a thin
H2 gas film around the Fe° particles, which occurs throughout the column. The precipitation of ferrous and calcium
carbonate minerals from anaerobic, high alkalinity ground water was also indicated by Wavelength Dispersive Spectros-
copy (WDS) and X-ray photoelectron microscopy (XPS). The precipitation of these minerals was believed to occur nearthe
influent end of the iron columns, where declines in calcium and alkalinity were observed. Schuhmacher et al. (1997)
similarly detected the presence of CaCO3 and FeCO3 on iron surfaces by using scanning electron microscopy (SEM) and
X-ray spectroscopy. Raman spectroscopy indicated that calcium carbonate was present as aragonite in the first 4 cm of
the granular iron columns. Mackenzie et al. (1997a) calculated that the precipitation of carbonate minerals and Fe(OH)2
throughout the column could only account for 0.3% and 1%, respectively, of the observed porosity loss. However, enough
H2 was produced by the anaerobic corrosion of iron in one day to account for a porosity loss of 10% within their column.
They suggested that the formation of a thin film of H2 gas around iron particles could account for the observed porosity loss
and that the precipitation of minerals may affect porosity over longer treatment times (Mackenzie etal., 1997b).
The porosity losses due to CaCO3 and Fe(OH)2 precipitation can be estimated from the observed ground-water
concentrations of Ca, alkalinity and iron corrosion rates. At ground-water flow velocities averaging 15 cm/day (Puls etal.,
1995), 50% estimated barrier porosity and concentrations of 100 mg/L CaCO3 (alkalinity), and assuming a molar volume of
35 mL/mol for CaCO3, a uniform porosity loss rate of 8.7 x 10~6 ml_mL1day-1 or 0.0009 %/day is calculated. At this rate, a
porosity decrease of 10% throughout the barrier would take 32 years. If the CaCO3 only precipitates within the first 10 cm
of the barrier, a porosity loss rate of 5.2x10'5 mLmL1day-1 is calculated for this zone. At this rate, the porosity of the front
of the barrier would decrease by 10% over about 5 years. As a worst case, if calcite precipitation concentrates in the front
5 cm or 2.5 cm of the barrier, a 10% reduction in porosity would be observed after 2.6 or 1.3 years, respectively. Siderite
may precipitate instead of calcite. If siderite precipitation occurs, the porosity will decrease 20% more slowly (e.g.,
6.2 years fora 10 cm zone), because of the lower molar volume of siderite (29.4 ml/mol).
Using an iron corrosion rate of 0.6 mmol Fe2+/kg Fe per day (Reardon, 1995) and a Fe(OH)2 molar volume of 26.4 mL/mol,
the porosity loss rate due to Fe(OH)2 precipitation would be 0.006% per day. At this rate, a uniform porosity loss of 10%
throughout the barrier would take 4.5 years.
Sulfate entering the barrier is consumed before discharging from the barrier. The sulfate may be reduced to sulfide, which
may then precipitate as an insoluble metal sulfide, such as iron sulfide (FeS, molar volume 24.4 ml/mol). Assuming an
average input concentration of 50 mg/L SO4, and that Fe2+ is available in excess, a 10% porosity loss in the front 10 cm of
the barrier would occur over 15 years, or 75 years over the full thickness of the barrier.
These calculations suggest that the precipitation of CaCO3 or FeCO3 at the front of the barrier and Fe(OH)2 or iron sulfide
throughout the barrier may be important in adversely influencing the porosity and hydraulic conductivity of the barrier over
long time periods. However, these calculations assume that all the minerals precipitate within the barrier and adhere to the
granular iron. In addition, the precipitation of Fe(OH)2 does not account for the original volume of Fe° that dissolves to form
Fe2+. The long-term impact of precipitate formation on barrier porosity is considered further in Volume 3.
Mineralogical study of barrier materials collected immediately after installation of the barrier (June 1996) and 6 months
later, in November 1996 confirmed that secondary Fe(OH)2 and ferric hydroxides (goethite) formed on iron within the barrier
after installation (Palmer, 1999). Secondary carbonates (siderite) were not unequivocally identified. Secondary sulfides
were not detected on the granular iron, though this may be a result of the small mass that would have formed in the six
month treatment period before the analysis (Palmer, 1999).
In terms of precipitate impact on reactivity, column studies with zero-valent iron conducted for more than three hundred
pore volumes indicate minimal loss in reactivity towards TCE (Cippollone et al., 1997). At ground-water velocities of
10 cm/day, this corresponds to a barrier lifetime of at least 5 years with a minimal decline in TCE reaction rate. Similarly,
laboratory column experiments (O'Hannesin et al., 1995; Blowes et al., 2000) indicated Cr(VI) front migration which
suggested breakthrough of Cr(VI) after 1,400-2,000 pore volumes. This would correspond to a barrier lifetime of between
19-28 years. These estimates suggest that the precipitation of minerals may have an impact on granular iron reactivity
towards Cr(VI) and TCE over a long time period.

Other Impacts
Apart from Na and Cl, the concentrations of all other major ground-water constituents (Ca, Cr, Mg, Mn, SO4, NO3and CO3)
decline within the barrier. The decreases in aqueous constituent concentrations, resulting from reduction and precipitation,
affect the electrical conductivity of the ground water. The electrical conductivity of a solution is proportional to the
concentrations of dissolved ions (Hem, 1982). Thus, as dissolved species are removed from solution by precipitation, the
electrical conductivity decreases. In transect 1, electrical conductivity values decrease from 230-880 u,S/cm upgradient of
the barrier, to 40-600 u,S/cm within and downgradient of the barrier (Figures 64,65). In transect 3, the electrical conductivity
decreases from 150-600 u,S/cm upgradient of the barrier, to 150-500 u,S/cm downgradient. Electrical conductivities were
similar in each of the sampling sessions. For comparison, electrical conductivity values were also calculated using
Onsager's limiting law expression and observed ground-water constituent concentrations (Hem, 1982). The distribution of
electrical conductivity calculated from the ionic concentrations is very similar to the observed electrical conductivity
(Figure 66).
Compliance Well Results
Chromium concentrations are below detection in all compliance wells downgradient of the barrier, for all sampling periods
(Table 7), suggesting that Cr(VI) is reduced by the granular iron barrier. The results indicate the barrier has removed
dissolved Cr throughout the two and one half-year monitoring period with no apparent decline in effectiveness.
In all sampling sessions, TCE concentrations are also below MCL values in MW47 and MW49, located immediately
downgradient of the reactive barrier (Figure 5; Table 8). These wells are screened over approximately the same depth
interval as the reactive barrier and represent concentrations that are averaged over the screened interval. The low TCE
concentrations (< MCL) measured in these compliance wells indicate that the granular iron is reducing TCE concentrations
in the ground waterthat flows through the barrier. The results suggest the effectiveness of the barrier has not declined over
the two and one half-year monitoring period.
TCE concentrations in MW46, located near the river and toward the western extent of the barrier (Figure 5), are greater than
the MCL value. However, the quality of water at MW46 with respect to TCE, seems to be improving with time. The TCE
concentrations at MW46 decreased from high values in November 1996 (256 ug/L) and February 1997 (636 ug/L) to values
< 75 ug/L in all sampling sessions other than March 1998. These results suggest that the reactive barrier is not intercepting
the western extent of the TCE plume.
TCE concentrations in MW50, a deep well immediately downgradient of the barrier, are greaterthan the MCL value. MW50
is located below the barrier for the purpose of monitoring the quality of the ground water flowing beneath the barrier. The
TCE concentrations in this compliance well tend to increase between sampling sessions, from < 50 ug/L in November 1996
and February 1997 to a maximum value of 548 ug/L in September 1997. Between March 1998 and December 1998, TCE
concentrations were lower, between 171 and 390 ug/L. The measurement of high concentrations of TCE in the deepest
piezometers in the barrier suggests that portions of the TCE plume extend beneath and are not intercepted.
The concentration of cDCE is equal to or less than MCL values (70 u,g/L) in all compliance wells in all sampling sessions
(Appendix C). Between November 1996 and September 1997, VC concentrations at the compliance wells downgradient of
the barrier were less than or equal to the MCL (2u,g/L). In March 1998 however, VC concentrations in MW46, 47, 49 and
50 first exceeded MCL, with values between 2.5 and 4.9 ug/L (Table 9). Data collected in 1998 indicate that VC
concentrations in the compliance wells started to increase after September 1997. In all of the 1998 sampling sessions, VC
values exceeded the MCL in compliance wells downgradient of the barrier. In December 1998, VC concentrations reached
a maximum value of 8.7 ug/L at MW46, located near the river and toward the western extent of the barrier. It is probable that
water at this compliance well was not fully intercepted and treated by the barrier. VC concentrations at the downgradient
compliance wells are not consistently above the MCL. At times, VC concentrations decrease below detection in some of
the compliance wells that in a previous session showed VC concentrations that exceeded the MCL. The periodic
breakthrough of VC at compliance wells located downgradient of the barrier may be a result of insufficient residence time
in the barrier.

Conclusions
A permeable reactive barrier containing Peerless™ granular iron was installed at the U.S. Coast Guard Support Center,
Elizabeth City, N.C., in June 1996. The performance of the barrier was monitored on seven occasions between November
1996 and December 1998. The highest concentrations of all major ground-water constituents, including Cr(VI) and
chlorinated organics, occur within a higher hydraulic conductivity zone, located at 4.5 to 6.5 m depth upgradient of the
barrier. Flow modeling suggests that ground-water flow occurs primarily in this zone, due to confinement by natural low
hydraulic conductivity zones upgradient of the barrier. Additional low hydraulic conductivity zones occur discontinuously
near the upgradient contact between the aquifer and the barrier. This low hydraulic conductivity possibly results from the
mixing of aquifer material and granular iron. Ground water preferentially flows within the higher conductivity zone toward the
granular iron barrier, where the Eh and pH change dramatically. The corrosion of granular iron by water, Cr(VI), SO4, NO3
and other oxidized species produces extremely low Eh conditions (e.g., Eh values below -500 mV SHE) and high pH
conditions (e.g., pH values that exceed 10). These changes in Eh and pH reflect a marked shift in the ground-water
chemistry. The only major ground-water constituents that remain unaffected are Na and Cl, two relatively conservative
species unaffected by changing redoxand pH conditions.
A review of the November 1996, February 1997 and December 1998 data indicates that most inorganic ground-water
constituents, including Cr(VI), are removed from the ground water in the vicinity of the reactive barrier by processes
including reduction and precipitation, which are favored under the Eh-pH conditions present within the barrier. Oxidized
species such as Cr(VI), SO4and NO3 are reduced within the barrier, while aqueous CO3 (expressed as alkalinity), Mn, Mg,
Ca, Fe and Cr(lll) concentrations decrease, possibly as a result of carbonate, sulfide and hydroxide mineral precipitation.
Geochemical calculations indicate that the saturation indices of various carbonate and hydroxide mineral phases exceed
zero within the barrier, suggesting that the precipitation of these minerals is thermodynamically favored. The electrical
conductivity of the ground water also decreases, as it is proportional to the concentrations of ionic species within the
ground water.
The precipitation of secondary minerals within the barrier may have an important impact upon the performance of the barrier
in terms of Cr(VI) reduction and the reductive-dechlorination of TCE and its daughter products. Precipitates may alterthe
reactivity of the granular iron by making the iron particle surfaces inaccessible, or may alter the ground-water flow velocity
and direction if the hydraulic conductivity or porosity of the barrier decrease. However, slug tests performed at the February
1997 sampling session indicate that the hydraulic conductivity of the granular iron is greater than 85 m/day and thus is
significantly greater than the hydraulic conductivity of the aquifer (1-16 m/day).
The dominant valence state of Cr in plume water is Cr(VI). Cr(VI) and total Cr concentrations decrease to less than the MCL
value of 0.05 mg/L within anddowngradientofthe barrier. The reactions within the barrier also decrease the TCE, cDCE
and VC concentrations to near or below their MCL values of 5 u,g/L TCE, 70 u,g/L cDCE and 2 u,g/L VC. In addition, the TCE
plume appears to be heterogeneously distributed with depth. Part of the plume occurs at depths below the barrier and the
deepest monitoring points. The presence of TCE concentrations above the MCL value at the deepest downgradient
monitoring points may indicate that this part of the plume flows beneath the barrier and is not treated.
TCE concentrations are reduced by orders of magnitude within the barrier, although TCE concentrations of up to 15 u,g/L
are observed downgradient. Similarly, VC concentrations are significantly reduced within the granular iron barrier, although
concentrations of up to 5 u,g/L persist downgradient. These concentrations exceed the MCL at only a few downgradient
sampling points and may indicate inadequate residence and treatment time within the barrier. Hydraulic conductivity
measurements indicate that low hydraulic conductivity zones upgradient of the barrier may focus flow through higher
conductivity zones, increasing ground-water velocities within the barrier. The mass of granular iron emplaced in the trench
(280 tons) was less than originally planned (450 tons). As a result, the granular iron density may be lower and granular iron
zone may be thinnerthan originally designed. Reactive transport simulations indicate that the observed breakthrough of
5 u,g/L VC within transect 2 would occur if the granular iron thickness was less than approximately 6-12 cm.
Results from the compliance wells indicate that contaminated ground water flowing through the barrier is treated
successfully to below the MCL values for Cr(VI) and cDCE at all times. TCE concentrations in two of the compliance wells
(MW47, MW49) located directly downgradient of the barrier also meet MCL values at all times. The compliance wells,
however, give contaminant concentrations that are averaged over a 1.5 or 3 m screened interval. The smaller 15 cm long
screened multilevel samplers indicate that breakthrough of TCE and VC slightly above MCL values occurs in localized
points downgradient of the barrier.
TCE concentrations in two other compliance wells exceed the MCL value periodically. One of these wells (MW46) is
located toward the western extent of the barrier and may represent water that was not fully intercepted and treated by the
barrier. The other well (MW50) is screened at depths below the barrier. The ground water in this well did not flow through and
was not treated by the barrier. The high TCE concentrations in this well confirm that part of the TCE plume extends below
the barrier, at depths greater than 7.3 m.
15
-------
VC concentrations in the compliance wells downgradient of the barrier were below MCL values between November 1996
and June 1997. Between September 1997 and December 1998, VC concentrations in these wells exceeded the MCL value
slightly. The periodic breakthrough of VC at these wells may be a result of insufficient residence time in the barrier, as
mentioned above.
The reviewed data suggest that the effectiveness of the granular iron at removing Cr(VI), TCE and cDCE has not
diminished over the two and one-half year monitoring period.

Appendix I Ground Water Sampling - Standard Operating Procedures
I. Disclaimer:
This standard operating procedure has been modified from the procedure prepared for the use of the Robert S. Kerr
Environmental Research Laboratory (RSKSOP-152, Revision 4) of the U.S. Environmental Protection Agency. This
procedure is suitable for University of Waterloo sampling at the U.S. Coast Guard Elizabeth City site and may not be
specifically applicable to the activities of other organizations.
II. Purpose: (Scope and Application)
This document describes the procedures used to obtain the most "representative" ground-water samples currently
possible from monitoring wells for the determination of ground water quality in general and specifically to determine
extent of contaminant release.
III. Summary of Method:
The following ground-water sampling procedure is based on several years of experience in sampling ground waters for
both metals and organic compounds (Puls and Barcelona, 1989; Puls et al., 1990; Puls et al. 1991; Puls and Powell,
1992; Paul and Puls, 1992). The primary limitations to the collection of "representative" ground-water samples are the
following: disturbance of the stagnant water column above the screened interval (e.g. mixing due to insertion of the
sampling device or ground water level measurement device); resuspension of settled solids at the base of the casing
(e.g. high pumping rates, raising and lowering a bailer); disturbance at the well screen during purging and sampling (e.g.
high pump rates, raising and lowering a bailer); introduction of atmospheric gases or degassing from the water (e.g.
sample handling, transfer, vacuum from sampling device etc.).
Samples should not be taken immediately following well development. A sufficient time should elapse to allow the ground
waterflow regime in the vicinity of the monitoring well to stabilize and to let chemical equilibrium with the well construction
materials be approached. This lag time will depend on site and installation specific parameters.
It is generally agreed that the purging of monitoring wells for the purpose of obtaining representative samples is
necessary in most instances. Ground-water chemistry can be altered through contact with the atmosphere, well casing
materials, screen, gravel pack and surface seal. Rather than using a general guideline of purging three casing volumes
prior to sampling, it is recommended that an in-line water quality indicator device be used to establish the equilibration
time for several parameters (e.g. pH, specific conductance, redox, dissolved oxygen, turbidity) on a well-specific basis
and the volume required for parameter equilibration then become the accepted (documented) purge volume.
With these limitations or constraints in mind, and acknowledging that it may in fact be impossible to obtain a perfectly
"representative" sample, the following general recommendations are made and incorporated into this procedure:
• the use of low flow rates (< 0.5 L/min), both during purging and sampling,
• placement of the sampling device intake at the desired sampling point,
• minimal disturbance of the stagnant water column above the screened interval (during water level measurement and
sample device insertion),
• monitoring of water quality indicators during purging,
• minimization of atmospheric contact with samples,
• collection of unfiltered samples for estimating contaminant loading and transport potential in the subsurface system.
These recommendations and much of the following assume the use of portable sampling equipment, that is,
non-dedicated systems. In the majority of cases, these methods will result in low turbidity samples precluding the need
for filtration, resulting in less sample handling and fewer sampling artifacts. Such a method would also include the
potentially mobile colloidal-associated metal contaminant fraction, which would otherwise be eliminated.

V. Procedure:
In advance of sampling set-up or opening of the wells, all sampling and monitoring equipment should be calibrated
according to manufacturers recommendations. Calibration of pH should be performed with at least two buffers that
bracket the expected range. Dissolved oxygen calibration must be corrected for local barometric pressure readings and
elevation.
A. Water Level Measurement
Use a device that will only disturb the uppermost portion of water in the casing. Well depth should be
obtained from the well logs. Measuring to the bottom of the well casing will only cause resuspension of
settled solids from the formation and require longer purging times for turbidity equilibration. The water level
measurement should be taken from the permanent reference point, which is surveyed in relative to ground
elevation. For the University of Waterloo small diameter multilevel monitoring system, the centre stock will
serve as the only water level monitoring point.
B. Sampling Device Insertion and Equipment Set-up
The sampling device intake should be slowly and carefully lowered to the middle of the screened interval or
slightly above the middle (e.g. 1.5-2.5 ft below the top of a 5 ft screen). This is to minimize excessive mixing
of the stagnant water above the casing with the screened interval zone water, and to minimize resuspension
of solids (i.e. fines) which have collected at the bottom of the well casing. These two 'disturbance' effects
have been shown to directly affect time for purging (i.e. time to reach equilibration of water quality indicator
parameters). Also there appears to be a direct correlation with size of sampling device and purge time (i.e.
increased time for increasing size of device). The key is to minimize disturbance of the water and solids in
the well casing. The monitoring points of the multilevel samples serve as dedicated samplers, which are
connected directly to a peristaltic sampling pump. These samplers will be pumped at low flow rates to
minimize disturbance effects.
C. Well Purging
In most cases the water in the well casing (particularly above the screened interval) is of different chemical
quality to that of the formation water due to a variety of physical, chemical and microbiological processes
which can occur overtime. The use of low flow (e.g. 0.1-0.5 L/min) pumps is suggested. These include
bladder pumps (e.g. GeoTech small dia. bladder pump; QED Well Wizard bladder pump), submersible
pumps (e.g. Grundfos Redi-Flo, 2 in. dia. pump), and peristaltic pumps. The peristaltic pump can cause
degassing resulting in alteration of pH, alkalinity, and some volatiles loss. All pumps have some minor
limitations and these should be investigated with respect to your particular application. The use of bailers is
strongly discouraged. Water level is continuously checked to monitor drawdown in the well as a guide to flow
rate adjustment. The goal is minimal drawdown (<0.3 ft) during purging. In-line water quality indicator
parameters should be continuously monitored during purging. The water quality indicator parameters
monitored can include pH, oxidation-reduction potential (redox), specific conductance, dissolved oxygen
(DO) and turbidity. The most sensitive of these parameters are the last three. Once documented, the time or
volume required to obtain equilibration of parameter readings, can be used as a future guide to purge time
135

or volume for that well. Measurements should betaken at least every three minutes if the above suggested
flow rates are used. Equilibration is achieved after all parameters have stabilized for three successive
readings. In lieu of measuring all 5 parameters a minimum subset would include specific conductance, DO
and turbidity. In the case of the small diameter multilevel sampling wells, the minimum subset will include pH
and Eh, which will be measured on-line in a sealed flow-through system. More specific equilibration
guidelines are the following: three successive readings are within ±0.1/min for pH, ±10 mV/min for redox,
±3%/min for specific conductance, ±10%/min for DO, and ±10%/min for turbidity. Equilibrated trends are
generally obvious and follow either an exponential decay or asymptotic trend during purging. Dissolved
oxygen and turbidity usually require the longest time for equilibration. The above equilibration guidelines are
provided as rough estimates based on experience. Upon parameter equilibration, sampling can be initiated.
The sequence in which samples are collected is immaterial unless there will be filtration. Filtering should be
done last and in-line filters should be used as discussed below.
D. Well Sampling
Upon water quality parameter equilibration, sampling should begin immediately and using the same device
as was used for purging. Ideally sampling should occur in a progression from least to most contaminated
well if this is known. During both well purging and sampling, proper protective clothing and equipment must
be used based upon the type and level of contaminants present.
E. Sample Containers & Filtration
The appropriate sample container will be prepared in advance of actual sample collection for the analyte of
interest including where necessary a sample preservative. The water sample should be collected directly
into this container from the pump tubing. Methods for sample handling and preservation are spelled out in
Handbook for Sampling and Sample Preservation of Water and Wastewater, EPA/600/4-82.
If samples are field-filtered, an in-line high-capacity filter should be used. The filters must be pre-rinsed
following manufacturer's recommendations. If there are no recommendations for rinsing, pass through a
minimum of 1 L of ground water following purging and prior to sampling. In-line filters are available in both
disposable (barrel filters) and non-disposable (in-line filter holder, flat membrane filters) formats and various
filter pore sizes (0.1-5.0 m).
F. Sampler & Equipment Decontamination
Specific decontamination protocols for sampling devices are dependent to some extent on the type of device
used and the type of contaminants encountered. The pump (including support cable and electrical wires
which are in contact with the sample) can be decontaminated by the following procedure:
1. Pump Alconox™ solution through the pump and tubing.
2. Pump water through the pump and tubing.
3. Where gross contamination by VOCs are encountered, pump methanol through the pump and
tubing.
4. Pump at least one system volume (pump, tubing, etc.) of distilled water through the pump and
tubing. All other equipment that comes in contact with contaminated groundwater can be
decontaminated similarly. The duration of flushing with de-ionized water following the use of
methanol shall be sufficiently long to ensure that all solvent has been rinsed out. This can be
monitored via a conductivity meter and probe. Equipment blanks shall be collected to monitor
the decontamination procedures.
G. Sample Blanks
The following blanks should always be collected:
1. field equipment/decontamination process blanks.
2. trip blank - sample bottle filled with laboratory-grade deionized water and stored and shipped
with samples.
H. Dedicated Well Pumps (specific to Elizabeth City site)
If the wells have dedicated pumps (bladder, electric submersible, peristaltic tubes) installed, studies at the
site have shown the need for little purging. A general guideline is 3 system volumes (pump, tubing, etc.)
purged prior to sample collection. One record of parameter equilibration should be established to verify this
for subsequent sampling events.

Appendix J Quality Assurance - Quality Control Narrative
A large number of samples were analyzed over the duration of the project (> 1,200 sets of samples) with a number of
analyses performed (> 40 per set). The data quality was assessed using blank samples, duplicate samples, and spike
recovery samples. The quality of the dataset is excellent.
Other than selected duplicate organic samples collected for UW, all groundwater samples collected at the Elizabeth City
site were analyzed by the ManTech Environmental Research Services Corporation, Ada, OK using methods developed
for, or recommended by, the EPA Subsurface Protection and Remediation Division (Appendix H). Once analyzed, the
complete analytical results, including quality control (QC) measures such as spikes, duplicates, known standards and
blanks, were reported to NRMRL-EPA. The groundwater results were organized and provided to UWby NRMRL-EPA
and did not include the QC results from ManTech. During the organization of the data at NRMRL-EPA, the QC measures
performed by the contract lab were examined and any unusual results were flagged in the datasets.
Duplicates
Analytical results for duplicate samples are shown in Tables J1-J4. Statistical analyses were performed on selected
organic (TCE, c-DCE and VC; Table J4) and cation (Na, K, Ca, Mg and Cr; Table J2) components of interest. The
replicate results are in good agreement. In general, the variability of the measurements is low and within acceptable limits
(< 5 % difference). The spread of the data, as indicated by percent relative standard deviation (RSD) calculations, is
< 10% and usually below 5%. As expected, larger percent differences and standard deviations were observed for
measurements approaching the detection limit.
Field and Trip Blanks
Results for the field/decontamination and trip blanks analyzed are presented in Tables J5-J7. Few contamination effects
were observed with the majority of the analytical results reported as ND or BLQ values. General observations and any
corrective measures implemented are described below.
Forthe target species of interest in this project, Cr and TCE, the field and trip blanks show few false positive results. The
majority of the field blanks had Cr values below the limit of quantitation with all field and trip blanks reporting
< 0.006 u,g/L Cr (Table J5). TCE contamination of the field and trip blanks was observed at only one sample point in
June, 1997 (1.1 u,g/L, Table J7) and is very close to the limit of quantitation of 1 u,g/L.
Sodium was detected at quantifiable concentrations in 65% of the field blanks and in 60% of the trip blanks analyzed, but
generally did not exceed 1 u,g/LNa (Table J5). Because the average field blank Na values for a particular sample session
represented only 0.6% to 2.3% of the average groundwater Na concentration measured forthattime, Na contamination
was considered a minor effect. The presence of sodium in the blanks may be attributed to a sample bottle contaminant
or, for the field blanks, incomplete rinsing of Alconox® solution from the sampling lines during decontamination
procedures. (Sodium is the primary cation in the Alconox® formulation.) This problem was addressed, although not
completely resolved, by rinsing the sample bottles with groundwater before sample collection and ensuring more
complete flushing of the sampling system with deionized water after the Alconox® rinse between sample points. Sodium
is a pervasive cation in the environment. With ICP detection limits approaching better than 1 u,g/L for this element,
prevention of contamination is difficult.
Field blanks collected along the ML2 transect in March, 1998 contain elevated Gland SO4 values of < 10u,g/L (Table J6).
The Cl concentrations are generally below the values measured in the piezometers previously sampled by the same
equipment, whereas the blank SO4 concentrations are higher. These effects were not observed in other sampling
sessions or at other locations and are probably due to incomplete rinsing of Alconox® from the sampling equipment
between sample points. Both Cl and SO4are present in the Alconox® cleaning solution, and at concentrations similar to
the measured contamination levels, 9 ppm Cl and 12 ppm S at the recommended 1% Alconox® dilution. Corrective
measures to alleviate this contamination included a more thorough rinsing of the equipment after the Alconox® flush.
c-DCE values of < 9, 8 and 3 u,g/L were observed along the ML2 transect in the field blanks for March, June and
December, 1998, respectively (Table J7). These measured values may be due to incomplete cleaning of sampling
equipment during sampling and are not attributed to Alconox® or bottle contamination. The problem was addressed,
although not completely alleviated, by ensuring more complete flushing of the sample manifold with Alconox® solution.
Few manifold (i.e. organic) cross-contamination problems were observed along the ML1 and MLS transects. All TCE,
137
-------
c-DCE and VC measurements on the trip blanks analyzed were below the limit of detection suggesting that the sample
bottles were not a source of organic contamination.
Comparison of Organic Samples Analyzed by ManTech and UW
Groundwater in the multilevel bundle piezometers was sampled using a modified version of the Standard Operating
Procedure RSKSOP-152 (Appendix I). Organic samples for analysis at UWwere collected in series in the manifolds to
ensure that relative comparisons could be made.
Concentrations of TCE and its degradation products were determined by headspace gas chromatography (GC) at the
University of Waterloo (described in Document I), and by automated purge and trap /GC analysis at ManTech according
to RSKSOP-146. The UW method requires that the partitioning of the analyte between the liquid and gas phase be at
equilibrium between the two phases, as opposed to being exhaustively extracted from the water, as is the case with
purge and trap techniques. Pentane extraction and headspace analytical techniques are especially suited for column
treatability studies and for groundwater samples from multilevel piezometers, because they can accommodate the small
sample sizes removed from ports along the column profile or from points along the piezometer bundle. At UW, a 1 ml
sample volume was needed for TCE analysis via an ECD, and a 1 ml sample volume was needed for DCE and VC
analyses via a PID. This is in contrast to the EPA recommended purge and trap GC method which requires a sample
volume of at least 5 ml for detection with an FID detector.
Table J8 compares the TCE, c-DCE and VC results for the organic field samples analyzed via the EPA purge and trap
and the UW headspace methods. Statistical analyses, including relative percent differences and standard deviations, are
reported. For the statistical calculations, values reported as BLQ or ND were set to 1 u,g/L, the limit of quantitation for
ManTech and UW analyses.
The TCE results between the ManTech and UW labs are in good agreement. In general, the variability of the
measurements is low and within acceptable limits, with relative differences < 7%. The spread of the data, as indicated by
the RSD, is < 10%. Approximately 48% of the organic samples analyzed at UW are higher in TCE concentration than
samples analyzed at ManTech suggesting a lack of bias between the two different analytical techniques. TCE samples
measured at the low end of the calibration curve (< 10 u,g/L) were reported with similar accuracy between the two labs.
In contrast to the TCE results, the c-DCE and VC measurements between the two labs agree to a lesser extent. With
c-DCE and VC present as degradation products of the TCE treatment process, the majority of the groundwater samples
analyzed by both labs are low in c-DCE and VC (< 10 u,g/L) and approach the detection limits for each analyte. Average
relative differences approach 20% for c-DCE and 24% for VC. The ManTech results for c-DCE and VC are consistently
higher, in 76% and 89% of the samples, respectively. In general, samples reported by ManTech as having measurable
c-DCE and VC concentrations below < 10 u,g/L were reported as ND by the UW lab. The differences in reported values
are probably due to the differences in analytical methods including calibration effects. For VC analysis at UW, a linear
calibration curves is utilized over a longer range (1- 700 u,g/L at UW vs. 1-100 u,g/L at ManTech), however, the majority
of the samples are near the lowest standard (10u,g/L). For c-DCE, both labs run similar calibration ranges (1 -1,000 u,g/L),
however, as is the case with VC, the majority of the samples are at the low end of the curve, near 10 u,g/L. Because small
variations in linear calibration curve setup, or differences in calibration standards, can cause large changes in results for
samples measured at the low or high end of a curve, the differing results in this range are not unexpected.
Data Quality
Considering the large number of samples collected during the project and the number of analyses performed, the quality
of the dataset is excellent. Sample collection and analysis sheets compiled during the project report few problems. All
field analyses were performed according to EPA recommended or approved protocols. The dataset was examined for
entry errors and unusual results or comments were flagged. Deviations of sample duplicates, field and trip blanks from
expected results are noted above and are considered minor. Differences between c-DCE and VC analyses at ManTech
and the UW labs are notable, however, both sets of analyses indicate that TCE and its degradation products are being
successfully removed from the site groundwater, as is Cr(VI), using the zero valent iron reactive barrier.
