Quarterly Sampling Results
The DMT sediment and surface water study was performed in accordance with the USEPA
technical approach for the evaluation of chromium in sediment (USEPA, 2005a), as
described in the Work Plan and Section 3 of this report. The quarterly sampling program
was conducted within the zone potentially impacted by chromium releases at or from DMT
and at reference locations to support the following objectives:
1. Characterize the nature and extent of chromium in pore water, surface water, and
sediment in the Patapsco River adjacent to DMT as compared to USEPA’s NRWQC
(as applicable) and concentrations measured at reference locations.
2. Evaluate the fate and transport of chromium based on the characterization of
geochemical conditions that govern the presence of chromium as Cr(III) versus
Cr(VI).
3. Provide data to support the human health and ecological risk assessments for DMT,
including concentrations of other COPR constituents at DMT relative to those
measured at reference locations.
This section presents the results of the four quarterly sampling events, including summaries
of the full data set across the seasons and quarterly data summaries that characterize
seasonal influences on analytical results. This section is organized as follows:
Section 5.1: Nature and Extent of Chromium at DMT
Section 5.2: Delineation of Geochemical Conditions that Influence Fate and Transport
of Chromium
Section 5.3: Distribution and Extent of Other COPR Constituents
Section 5.4: Comparison to Results from Previous Studies Conducted in Baltimore
Harbor
A summary of the data validation procedures and reports are provided in Appendix D, and
full analytical results are provided in Appendix E. The data validation process
demonstrated and documented that analytical data were within the acceptance criteria for
the associated methods, and are of sufficient quality to be used for qualitative and
quantitative purposes. The only exception to this determination related to SEM mercury
results for four sediment samples collected in the first quarterly sampling event 1 . Overall,
the validation has demonstrated that the quality of the data is sufficient for achieving
project objectives and can be used both in the characterization of chromium and other COPR
constituents at DMT as well as the evaluation of risks, and thus is of sufficient quality for
risk-management decision making. Specifically, as detailed below, the DMT data are

non-recovery of mercury in the matrix spike and matrix spike duplicate. However, the non-recovery of the spiked mercury can
be attributed to the nature of the AVS extraction, and not to the sediment sample matrix.

sufficient to support the conclusion that the nature and extent of chromium in the Patapsco
River and Colgate Creek are delineated, in accordance with the approach defined in the
Work Plan, and as such, meet the requirements as stipulated in the Consent Decree.
5.1 Nature and Extent of Chromium
Results for chromium in all media are presented in Tables 5-1 to 5-4, which show the
detection frequency, the range of detected concentrations, the average concentration, and
the location-specific results for pore water, surface water, surficial sediment (0 to 6 inches)
and subsurface sediment (approximately 6 inches to 3 feet below sediment surface),
respectively. The maximum detected concentrations of Cr(VI) and total chromium in each
medium during any sampling event is illustrated on Figure 5-1a. Pore water, surface water,
and sediment results for chromium are discussed in detail below.
5.1.1 Nature and Extent of Chromium in Pore Water
Pore water results for DMT and the three reference locations for the May 2007 through
February 2008 sampling efforts are presented in Tables 5-1a (DMT locations) and 5-1b
(reference locations), and illustrated on Figure 5-1b. Pore water was collected from each
location during each quarter of sampling, with very limited exceptions when the volume of
pore water extracted from the sediment was insufficient to conduct any or all of the
chemical analyses. Those sampling locations and the associated sampling event are
specifically identified in Table 5-1a.
Hexavalent Chromium in Pore Water
Cr(VI) was not detected in pore water in any of the samples taken from DMT in any of the
sampling events. The detection limit of 5 μg/L was well below the USEPA’s saltwater acute
and chronic NRWQC for Cr(VI) (1,100 and 50 μg/L, respectively). According to USEPA and
published scientific studies, if Cr(VI) were present in sediment and biologically available, it
would be detected in pore water (USEPA, 2005a; Berry et al., 2004; Besser et al., 2004). The
absence of measurable Cr(VI) in pore water establishes that neither whole sediments nor
pore water is contaminated with Cr(VI). The absence of Cr(VI) in pore water also
demonstrates that Cr(VI) is not being transported to the Patapsco River via groundwater
upwelling. The lack of measurements of Cr(VI) in pore water confirms that the nature and
extent of Cr(VI) in pore water and sediment is defined.
Dissolved Total Chromium [Cr(III)] in Pore Water
As discussed in Section 3.2, USEPA NRWQCs are based on chromium as Cr(VI) and Cr(III).
The absence of Cr(VI) in pore water as discussed above indicates that the dissolved total
chromium that is present is in the form of Cr(III). Unfiltered total chromium concentrations
(hereafter referred to as total chromium) are also shown in Table 5-1a.
Cr(III) was detected in 70 of 131 pore water samples from the four quarterly sampling
events at concentrations ranging from 2.3 to 16.2 μg/L (mean = 3.7 μg/L), with little
variation between individual sampling events. The Cr(III) concentrations detected in pore
water from DMT locations were consistent with or less than those at the three reference
locations (mean = 6.5 μg/L; Figure 5-1b). Most importantly, however, concentrations of
Cr(III) at both DMT and reference locations were well below each of the NRWQC, the

SECTION 5—QUARTERLY SAMPLING RESULTS
freshwater acute and chronic criteria as well as the hardness-adjusted acute and chronic
criteria as illustrated on Figure 5-2a.
Concentrations of Cr(III) in pore water were significantly lower at the shallow water
Transects A, B, C and J than at the deeper water Transects D–H (p < 0.05; Figure 5-2b).
Transects A, B, C and J are the areas with the highest total chromium concentrations in
sediment (see Section 5.1.3). Cr(III) in pore water was detected in 79 percent of the samples
in Transects D–H, but only 20 percent of the samples at Transects A, B, C and J. Dissolved
Cr(III) is typically found associated with DOC, and Transects A, B, C and J have mostly
sandy sediments that contain lower concentrations of organic carbon.
There was no discernable relationship between Cr(III) in pore water and total chromium
concentrations in sediment from DMT or reference locations as evidenced by the fact that
Cr(III) in pore water was below the mean detected value at the surficial sediment sampling
locations with some of the highest total chromium concentrations. Transects D and E near
the 13th and 12th Street outfalls, respectively, show a trend of decreasing Cr(III)
concentrations with distance from the shoreline; however, this trend was not apparent at the
other transects (Figure 5-1b). There was no apparent clustering of higher Cr(III)
concentrations adjacent to the shoreline or in the outfall areas. Finally, there are no
significant relationship between concentrations of Cr(III) in pore water and location relative
to the dredged channels.
The measurements of dissolved Cr(III) in pore water well below the NRWQC confirm that
the nature and extent of Cr(III) in pore water are defined.
5.1.2 Nature and Extent of Chromium in Surface Water
Cr(VI) and total chromium surface water results for the May 2007 through February 2008
sampling events are presented in Tables 5-2a (DMT locations) and 5-2b (reference locations)
and illustrated on Figure 5-1c. Note that dissolved total chromium in surface water can be
Cr(III), Cr(VI), or a mixture of both. Dissolved total chromium is assumed to be Cr(III) if
Cr(VI) is not present.
Surface water samples were collected from up to three discrete depths as described in
Section 4.1.1 at DMT and reference locations during each of the four quarterly sampling
events.
Hexavalent Chromium in Surface Water
Cr(VI) was not detected in 97 percent of the surface water samples analyzed 1 and in those
limited locations where it was detected, concentrations were well below the USEPA’s
NRWQC. The majority of detected concentrations were at or near the detection limit.
Detected concentrations were consistently identified in areas adjacent to stormwater
outfalls, and with limited exception followed wet weather events.
In total, Cr(VI) was detected in 9 of 320 DMT surface water samples (excluding two
duplicate samples). Cr(VI) was not detected in surface water at the reference locations.
Cr(VI) was detected at sampling locations B3, B4, C1, D1, D3, E1 and E2 at concentrations
ranging from 6 to 35 μg/L (Figure 5-1c). Cr(VI) was detected in three consecutive sampling

SEDIMENT AND SURFACE WATER STUDY REPORT
events at sampling location E1 but was not detected more than once at the other six
sampling locations. Six of the nine Cr(VI) detections in surface water occurred during
rainfall events (Table 5-5). The remaining three detections were in samples collected when
rain occurred within 3 days of sampling. Typically, the detections occurred in the
uppermost sampling interval (approximately 3 feet below the air-water interface). The
concentrations of Cr(VI) reported in the surface water at DMT were all below the Cr(VI)
saltwater acute and chronic NRWQC of 1,100 and 50 g/L, respectively (Figure 5-3a).
There is evidence that the Cr(VI) detected in surface water is rapidly reduced to Cr(III)
because at locations where Cr(VI) was found at concentrations above 25 g/L (B-4 and E-1),
concentrations of dissolved total chromium were significantly higher than the site average
of 2.2 g/L, ranging from 26 to 44 g/L. The reduction of Cr(VI) to Cr(III) by natural
organic matter in the water column is consistent with findings from JHU studies (described
further in Section 5.4).
Given the low detection frequency, no discernable pattern of Cr(VI) concentrations with
increasing distance from the shoreline was evident, with Cr(VI) detections at both near and
far shore sampling locations (Figure 5-1c). There was no relationship between Cr(VI)
concentrations in surface water and concentrations of chromium in sediment or pore water
(as total or dissolved total chromium). Finally, there was no discernable relationship
between key sediment constituents that may influence chromium speciation (i.e. Fe(II), AVS,
organic carbon) and the presence or absence of Cr(VI). This serves as additional evidence
that the Cr(VI) detections in surface water do not originate from and are not related to
concentrations of chromium in sediment.
The DMT stormwater outfalls are in the same vicinity as Transects B–E where Cr(VI) was
detected (Figure 5-1c). The fact that Cr(VI) was detected during or after rainfall events
suggests a potential source of Cr(VI) from these outfalls. Figure 5-3b illustrates the
relationship between Cr(VI) detections in surface water and corresponding rainfall events.
However, Fe(II) and DOC were detected in approximately 70 and 80 percent of surface
water samples, respectively, indicating that Cr(VI) in the river is likely rapidly reduced
upon interaction with key reductants in the water column and sediment.
These Cr(VI) results are consistent with the CSM showing that during the occasions when
wet weather stormwater discharges are occurring, the influence of Cr(VI) on the adjacent
water body is minimal even in the area where the least mixing/dilution occurs, at least in
part because Cr(VI) is rapidly reduced to Cr(III). The measurements of Cr(VI) in surface
water well below the NRWQC confirm that the nature and extent of Cr(VI) are defined.
Dissolved Total Chromium in Surface Water
Dissolved total chromium was detected in 19 percent of samples from the four quarters of
sampling, at concentrations ranging from 2.3 to 37.6 μg/L (mean = 2.2 g/L 1 ). These
concentrations are well below the acute and chronic NRWQC for Cr(III) (Figure 5-4). In
samples where dissolved total chromium was detected in surface water, 94 percent of DMT
samples were at or near the detection limit of 2.3 g/L. Dissolved total chromium was
1 The mean is lower than the minimum value because the minimum value reported is the minimum detected value, whereas
the mean is based on the entire data set, with a value of one-half the detection limit used for samples where chromium was not
detected.

SECTION 5—QUARTERLY SAMPLING RESULTS
detected in 14 percent of reference samples and concentrations were not significantly
different than dissolved total chromium concentrations at DMT (reference mean = 1.4 g/L;
r = <0.05). Moreover, there was very little variation in dissolved total chromium
concentrations between sampling events.
Dissolved total chromium concentrations in surface water appear to decrease with distance
from the shoreline at Transects C, D and E. There were no notable trends in dissolved total
chromium concentrations in surface water in shallow (A, B, C and J) versus deep water
transects (D–H; Figure 5-1c). There were also no significant trends in concentrations of
dissolved total chromium from within the dredged channels. Finally, while there appears to
be a trend of higher dissolved total chromium concentrations in the uppermost water
column interval versus the bottom waters, the trend is not statistically significant. The most
significant relationship is between concentrations of dissolved total chromium in surface
water and the few detected concentrations of Cr(VI) as discussed above.
The measurements of dissolved total chromium in surface water at concentrations well
below the NRWQC and consistent with reference locations confirms that the nature and
extent of chromium in surface water are defined.
5.1.3 Nature and Extent of Chromium in Sediment
Surficial (0-6 inches) and subsurface sediment samples (to a depth of 3 feet below the
sediment water interface) were collected at the locations indicated in Figure 5-1b using
methodologies described in Section 4.1.2. Surficial samples were collected in May and
August 2007, and subsurface samples were collected in August only. An additional Transect
J and one station on Transect B were added for sediment collection and analysis in February
2008 to further characterize the nature and extent of chromium at DMT. The results for the
combined sediment data sets are discussed in detail below.
A total of 41 locations were sampled near DMT from three depths: 0–6 inches, and two 6–
inch subsurface intervals that were selected based on sediment lithology and stratigraphy.
Results are summarized in Table 5-3a and 5-3b. The primary findings associated with the
sediment sample results are as follows:

The highest concentrations of total chromium in surficial sediment were found
proximate to Area 1501/1602 where concentrations were higher than the Site-wide
average and reference areas. Surficial chromium concentrations were also higher than
reference in Transect I.

Overall, concentrations of total chromium in surficial sediment declined with distance
from the shoreline, with total chromium concentrations at sampling locations furthest
from the shoreline similar to reference concentrations at Transects A, B and D
through H.

Geochemical parameters in sediment provide compelling evidence of geochemical
conditions that favor the presence of chromium as Cr(III) rather than Cr(VI), which is
consistent with the CSM for DMT.
Total chromium results for surficial and subsurface sediment samples are discussed in detail
below.

SEDIMENT AND SURFACE WATER STUDY REPORT
Total Chromium in Surficial Sediment
Results for total chromium in surficial sediment are presented in Tables 5-3a (DMT
locations) and 5-3b (reference locations) and illustrated on Figure 5-1b. Chromium was
detected at every location sampled at DMT and reference areas.
Concentrations of total chromium in surficial sediments near DMT ranged from 33 to
2,360 mg/kg (mean = 394 mg/kg). While chromium concentration in surficial sediments
Site-wide were significantly greater than the reference locations (range = 89.2 to 166 mg/kg;
mean = 127 mg/kg; p < 0.05), chromium concentrations at Transects D–H (mean =
156 mg/kg) were consistent with concentrations seen at the reference locations.
The highest concentrations of total chromium in surficial sediments at DMT were seen
closest to the shoreline at Transect J, adjacent to Area 1501/1602. Concentrations of total
chromium in surficial sediments at Transect J range from 1,260 to 2,360 mg/kg (mean =
1,820 mg/kg). Concentrations of total chromium from the four transects closest to Area
1501/1602 (shallow Transects A, B, C and J) have total chromium concentrations ranging
from 58 to 2,360 mg/kg (mean = 719 mg/kg), which are higher than total chromium
concentrations at the deep water Transects D–H (range = 33 to 310 mg/kg; mean =
156 mg/kg; p < 0.05). Surface sediments in Colgate Creek (Transect I) have total chromium
concentrations between these two groups (mean = 410 mg/kg). There is a trend of
decreasing chromium concentrations with increasing distance from the shoreline in
Transects A, B and C. Total chromium concentrations at sampling locations furthest from
the shoreline were similar to reference concentrations at Transects A, B, and D through H.
Total Chromium in Subsurface Sediment
Subsurface sediment samples, collected at two discrete intervals between 0.5 and 3 feet
deep, were collected at DMT in August 2007 and February 2008. Results are presented in
Table 5-3c and 5-3d and Figure 5-1b. Total chromium concentrations in subsurface sediment
from DMT ranged from 1.2 to 8,140 mg/kg (mean = 372 mg/kg). Concentrations of total
chromium in subsurface sediment from the reference locations ranged from 55 to
147 mg/kg (mean = 86 mg/kg).
The average concentration of total chromium in subsurface sediment at combined Transects
A, B, C and J, which are all within close proximity to Area 1501/1602, is 674 mg/kg. These
concentrations are higher than concentrations measured in subsurface samples from deep
Transects D-H (mean = 111 mg/kg; p < 0.05), which are similar to the reference areas. Total
chromium concentrations in subsurface sediment decrease with increasing distance from the
shoreline in Transects A and C in Area 1501/1602. Total chromium concentrations appear to
increase with distance from the bulkhead at Transect B and Transect I in Colgate Creek.
Conclusions Regarding Chromium Distribution in Surficial and Subsurface Sediment
Total chromium concentrations in surficial and subsurface sediments were highest near
Area 1501/1602 and at Transect I in Colgate Creek. Concentrations in Area 1501/1602
generally decreased with increasing distance from the shoreline and with increasing depth
in the sediment column. In Transect I in Colgate Creek, the highest concentrations were
found at depth at the location furthest from DMT. Transects D–H have mean total
chromium concentrations that are statistically similar to reference areas.

DOCUMENT FILE LOC: 4.3.3.3.3
SECTION 5—QUARTERLY SAMPLING RESULTS
The higher concentrations of total chromium in sediment immediately adjacent to Area
1501/1602 are likely related to historical stormwater runoff from uncovered COPR
stockpiles and other filling operations prior to placement of the asphalt cover. Prior to
construction of Area 1501/1602, approximately 800,000 cubic yards of COPR were
stockpiled in the southeast corner of DMT. During this period, stormwater runoff
containing Cr(VI) from the stockpiles entered the Patapsco River at the former shoreline that
is now occupied by Area 1501/1602. The runoff was eventually contained by earthen dikes
and sumps installed by MPA. Over 200,000 cubic yards of material were then placed in
containment cells above the water table during construction of Area 1501/1602. During
construction, clean fill material was deposited into the river to allow construction of the
containment cells. This filling process likely displaced the sediments affected by previous
stormwater runoff outward into the river in a progressive mud wave as the filling
advanced. Therefore, it is likely that sediment samples collected near the current shoreline
of Area 1501/1602 contain chromium contributions from historical runoff. Total chromium
in sediment in the vicinity of Transect C may also be due to historical releases of Cr(VI) via
the stormwater outfalls that reduced to Cr(III), which precipitated from the water column
and accumulated in sediment.
Groundwater upwelling does not appear to contribute to chromium in sediments because
Cr(VI) concentrations in groundwater samples from the perimeter of Area 1501/1602 are
below the NRWQC, Cr(VI) was not detected in pore water samples, and chromium
concentrations are higher in surficial sediment than in subsurface sediment, which is
inconsistent with a discharging groundwater source.
The limited horizontal extent of the elevated chromium concentrations indicates that
minimal sediment resuspension and transport has occurred. Results for Cr(VI) and Cr(III) in
pore water samples from locations in Colgate Creek indicate that additional investigation of
nature and extent of chromium in this area is not required.
Based on these findings, and given that Cr(VI) and total dissolved chromium concentrations
in pore water and surface water from all DMT locations are well below the NRWQC, the
nature and extent of total chromium in sediment is defined.
5.2 Delineation of Geochemical Conditions that Influence Fate
and Transport of Chromium
As discussed in Section 3.2, geochemical parameters can be used to understand and predict
chromium behavior in an estuarine environment. These parameters were analyzed during
each of the four quarterly sampling events. Characterizing in situ geochemical conditions is
critical to understanding the behavior of chromium, and provides insight into the
distribution, toxicity, and long-term stability of chromium in sediments. This section
describes both spatial variations in geochemical constituents at DMT as well as the influence
of season on the concentration of these constituents, and evaluates whether these variations
influence the behavior of chromium at DMT.
The most important constituents that reduce Cr(VI) to Cr(III) include sulfides, Fe(II), and
natural organic matter (Hansel et al., 2003). While sulfides and Fe(II) are able to donate
electrons for Cr(VI) reduction, organic carbon, specifically humic and fulvic acids, contain
HONEYWELL SITE#: R37825

SEDIMENT AND SURFACE WATER STUDY REPORT
binding sites that can form complexes with chromium and reduce its bioavailability.
According to USEPA (2005a), the presence of detectable AVS alone is an indication that any
chromium in sediment would be present primarily as Cr(III).
Results for geochemical parameters in pore water, surface water, and sediment are provided
in Tables 5-1 through 5-4. Spatial and temporal variations in geochemical conditions are
described below.
5.2.1 Spatial Variations in Geochemical Constituents
To evaluate spatial variations in geochemical conditions, results for geochemical parameters
at DMT locations were compared to those at the reference locations. Additionally, results for
samples from the shallow, sandy transects (Transects A, B, C, and J) were compared to those
from the deeper transects with finer-grained sediments (Transects D-H). While
concentrations of AVS and Fe(II) were not significantly different in Site versus reference
sediments, concentrations of TOC were significantly higher in the reference sediments
(mean = 2.9 percent) than in Site sediments (mean = 1.8 percent; p < 0.05). However,
concentrations of DOC were similar in surface water and pore water at the Site versus at the
reference locations. Overall, concentrations of geochemical constituents in all media,
including AVS/sulfides, Fe(II), and organic carbon, were substantially lower in the sandy,
shallow transects (Transects A, B, C and J) than in the silty deeper Transects (Transects D–
H). Despite the lower concentrations of these reducing agents in Transect A, B, C and J,
there is a surplus of reducing capacity in these sediments to insure the stability of Cr(III), as
evidenced by the fact that Cr(VI) was not detected in pore water at any location. Figure 5-5a
clearly demonstrates that concentrations of reducing agents are found in excess in all DMT
sediments.
5.2.2 Seasonal Variations in Geochemical Conditions
Seasonal variations in temperature and freshwater input may impact concentrations of key
geochemical constituents. Estuarine sediments, such as those in Baltimore Harbor, tend
toward anoxic or hypoxic conditions during summer months due to diminished freshwater
inputs, high water temperatures, and increased biological activity; which leads to increased
oxygen consumption. This results in an increase in the decay of organic matter and blooms
of macroalgae throughout the estuary that consume oxygen in the sediment and water
column. This decrease in oxygen concentrations is accompanied by an increase in sulfide
and Fe(II) production. Reduction and subsequent immobilization of Cr(VI) results from a
coupled biotic-abiotic reaction pathway in which Fe(II) or hydrogen sulfide (H2S) produced
during microbial respiration catalyze the reduction of Cr(VI).
The geochemical measures of AVS and Fe(II) showed very strong evidence that there was
adequate AVS and/or Fe(II) throughout the Site and during all seasons to maintain the
reducing conditions that would ensure the presence of chromium as Cr(III), as illustrated on
Figures 5-5a and 5-5b. Figure 5a shows that even in the limited number of areas where AVS
measures were low, there were substantial amounts of excess Fe(II) indicating reducing
conditions (and thus, the presence of chromium as Cr(III)). Figures 5-5a and 5-5b show
seasonal fluctuations, and despite fluctuations in temperature and freshwater inputs that
influence concentrations of DO, concentrations of reducing agents in sediments such as AVS
and Fe(II) remain substantial. Specifically, AVS was found in concentrations that exceed
concentrations of SEM in 90 percent of samples, regardless of season or DO concentration.
5-8
HONEYWELL SITE#: R37825
DOCUMENT FILE LOC: 4.3.3.3.3
SECTION 5—QUARTERLY SAMPLING RESULTS
As discussed previously, USEPA acknowledges that geochemical factors determine both the
bioavailability of chromium and its oxidation and reduction potential (USEPA, 2005a). As
shown in Figure 5-5b, regardless of the variations in DO concentrations with season or
depth at DMT, the concentrations of reducing agents are sufficient to ensure that chromium
is stable as Cr(III). At the few locations where AVS was not found in excess, Fe(II) was
available to act as the key reductant in the sediment (Table 5-4) as well as in surface and
pore water. The results demonstrate that chromium remains stable as Cr(III) and is not
oxidizable in even moderately oxidizing (aerobic) conditions. These results are also very
consistent with findings of JHU researchers and researchers at other estuarine sites, as
described in Section 5.4.
Chromium is stable as Cr(III) at DMT because reduction processes out-compete oxidation
processes, despite fluctuations in concentrations of various geochemical constituents.
Concentrations of reducing agents available to reduce Cr(VI) to Cr(III) far exceed the
concentrations of the few oxidizing agents known to oxidize Cr(III) to Cr(VI) even in
moderately aerobic sediments (Eary and Rai, 1987; Stanin, 2005). Furthermore, while
oxidation of Cr(III) is extremely slow in environmentally relevant geochemical and
thermodynamic conditions, reduction of Cr(VI) is very rapid under reducing or even mildly
oxidizing conditions, making reduction the favored reaction under environmentally
relevant pH/redox conditions (Schroeder and Lee, 1975).
5.3 Distribution and Extent of Other COPR Related
Constituents
Although the Work Plan focused on the characterization of chromium in sediment and
surface water adjacent to DMT, other COPR constituents (aluminum, calcium, iron,
magnesium, manganese, and vanadium) were also analyzed to provide data for the human
health and ecological risk assessments. Sample results for pore water, surface water, and
sediment are provided in Tables 5-1 through 5-3.
The analytical results for the other COPR constituents in surficial sediments are shown in
Figure 5-6. The spatial distributions vary for each parameter, indicating that these
constituents do not co-occur. Aluminum and iron concentrations tend to be lower in the
sandy sediments near Transects A-C relative to the finer-grained sediments in Transects DH and the reference locations. Calcium and magnesium concentrations tend to be highest
along the shoreline of Area 1501/1602. Manganese concentrations are highest along the D
and E transects, and vanadium concentrations are generally uniform throughout DMT and
in the reference locations. Concentrations of other COPR constituents in surficial sediment
have been delineated relative to reference concentrations.
5.4 Comparison to Results from Previous Studies Conducted
in Baltimore Harbor
This section includes a discussion of studies conducted by JHU and other researchers at
estuarine sites where chromium is a primary constituent of interest. The results from the
DMT study are consistent with the findings of these other research efforts regarding the
behavior, predictability and stability of chromium in sediments. Each of the studies

presented below used approaches consistent with the USEPA approach for evaluating
chromium toxicity in different media which includes the direct measurement of chromium
species (Cr(VI) and Cr(III)) and geochemical parameters such as AVS and Fe(II) (Berry et al.,
2004; USEPA, 2005a). These studies are discussed briefly below and are discussed in
significant detail in a chromium literature review (ENVIRON, 2008).
This section concludes with a discussion of the relationship of DMT findings to historical
studies at DMT, as well as the similarities of DMT findings from other chromium-related
sites (i.e., the JHU and peer reviewed studies described in this section).
5.4.1 Johns Hopkins University Center for Contaminant Transport, Fate, and
Remediation
JHU’s CTFR performed a series of comprehensive multi-year experiments to evaluate the
relationship between the presence of chromium species and toxicity in Baltimore Harbor
sediments, pore water, and the water column. The initial investigations by JHU researchers
characterized chromium speciation in Baltimore Harbor sediments and pore water (Graham
et al., 2009). The characterization study was followed by a series of experimental studies
using Baltimore Harbor sediments to evaluate chromium stability (Graham and Wadhawan,
2007a,b). The characterization and experimental studies are summarized below.
Baltimore Harbor Sediment and Pore Water Characterization (Graham et al., 2009)
The JHU researchers evaluated the geochemistry and speciation of chromium in sediment
and pore water from 22 Baltimore Harbor locations using a reverse-phase ion-pair high
performance liquid chromatography/inductively coupled plasma-mass spectrometry
(HPLC/ICP-MS) method. The sample locations in the study included one location from
DMT and two locations in Colgate Creek. The study included consideration of geochemical
parameters that indicate reducing conditions and thus contribute to the understanding of
chromium speciation (e.g. AVS, Fe(II), Mn(II), TOC). The researchers concluded that their
findings were consistent with the USEPA EqP model for chromium which indicates that
Cr(VI) is unlikely to be present in sediments with measurable AVS concentrations. Their
findings further showed that Harbor sediments have considerable capacity to reduce Cr(VI)
to Cr(III) based on spiking studies that were performed as part of method validation.
JHU CTFR Experimental Studies on Chromium Stability
The CTFR studies included multiple experimental studies that focused on two key questions
related to chromium stability:
1. What geophysical conditions in sediment promote the reduction of Cr(VI) to Cr(III), and
how fast are these reduction processes?
2. Once Cr(VI) is reduced to Cr(III), will the chromium remain as Cr(III) or can it be reoxidized to Cr(VI)?
JHU Experiment 1: Determination of Conditions Conducive to the Reduction of Cr(VI) to Cr(III) in
Aquatic Environments and Sediment (Graham and Wadhawan, 2007a)
Graham and Wadhawan (2007a) conducted a study to better understand the fate and rates
of reduction of Cr(VI) entering Baltimore Harbor. The study results showed that Cr(VI) was
reduced to Cr(III) in a matter of seconds when spiked into harbor and creek sediments. The

amount of Cr(VI) used in several of the experiments was 10 times the Cr(VI) NRWQC for
marine ecosystems. Study results also showed that the reduction of Cr(VI) was highly
correlated to AVS concentrations. The rate of reduction was in fact proportional to the
sediment AVS concentration and, therefore, consistent with USEPA guidance (2005a). The
researchers concluded that AVS was a good predictor of Cr(VI) reduction kinetics in
Baltimore Harbor sediments and that in sediments containing AVS, Cr(VI) is very quickly
reduced to Cr(III).
JHU Experiment 2: Study to Determine the Likelihood that the Reduction of Cr(VI) to Cr(III) will
be a Permanent Process—Cr(III) Oxidation (Graham and Wadhawan, 2007b)
An extension of JHU’s initial study was to evaluate whether the reduction of Cr(VI) to
Cr(III) is a permanent process. The primary objective of this study was to determine the
significance of oxidants (e.g., manganese oxides and oxygen) in transforming Cr(III) to
Cr(VI) in pore water, sediments and the water column. The researchers found that oxidants
introduced into an experimental vessel containing Baltimore Harbor sediments were
quickly reduced by organic matter, which is found in abundance in harbor sediments as
well as DMT. The researchers found that while it was possible to catalyze the reaction of
Cr(III) to Cr(VI), the specific conditions necessary to catalyze the reaction are not consistent
with conditions occurring in the natural environment. This study demonstrated that Cr(III)
is very stable in sediments unless under extreme laboratory conditions that are not
characteristic of conditions likely to be encountered in Baltimore Harbor. Therefore, the
authors concluded that the reduction of Cr(VI) to Cr(III) can be considered a permanent
process. These results are consistent with the findings at DMT in that regardless of seasonal
variations in temperature and concentrations of DO, chromium in sediments does not
oxidize to Cr(VI). If oxidation were occurring in sediments, then Cr(VI) would have been
detected in the pore water.
These findings by Graham and Wadhawan (2007b) are in agreement with the peer reviewed
literature that indicates that once reduced, Cr(III) is geochemically stable and unlikely to
transform to Cr(VI), even in the presence of oxidizing agents such as DO and manganese
oxides (Magar et al., 2008; Saleh et al., 1989; Eary and Rai, 1987). According to the results of
numerous peer reviewed articles, the oxidation of aqueous Cr(III) solely by DO is too slow
to be considered a significant factor in the formation of Cr(VI) (Rai et al., 1986, Schroeder
and Lee, 1975, Eary and Rai, 1987, Nakayama et al., 1981). The slow oxidation kinetics
enable Cr(III) to be involved in other reactions (sorption or precipitation) that are much
faster (Stanin, 2005) and maintain chromium in its reduced form as Cr(III). Thus, in the
event that the water quality conditions in Baltimore Harbor improve in the future, it would
still be highly improbable for the redox capacity of the sediments to be altered to the extent
necessary for the spontaneous formation of Cr(VI).
While several studies other than JHU have reported the manganese oxide catalyzed
oxidation of Cr(III) in the laboratory, the conditions necessary to drive the reaction are
artificial and are inconsistent with the in situ conditions at DMT. Cr(III) must be soluble
and/or manganese oxides must be fresh and amorphous in order for Cr(III) to adsorb onto
manganese oxides surface sites (a necessary step for Cr(III) oxidation by manganese oxides;
Wu et al., 2005; Kim et al., 2002). According to Wu et al. (2005) aged and well-crystallized
MnO2 (i.e., pyrolusite), which is what would typically be found in sediments, is weak and
slow to oxidize Cr(III). Also, Cr(III) has very low solubility at environmentally relevant pH
HONEYWELL SITE#: R37825

5-11
SEDIMENT AND SURFACE WATER STUDY REPORT
due to the formation of insoluble hydroxide and oxide compounds and because Cr(III)
forms strong complexes with sediment minerals and organic ligands (Fendorf, 1995).
Therefore, manganese oxides and Cr(VI) should not exist under the Eh-pH conditions
present at DMT.
Overall, the CTFR studies determined that nontoxic Cr(III) is favored in Baltimore Harbor
waters because the concentrations of reducing agents available to reduce Cr(VI) to Cr(III) far
exceed the concentrations of the few oxidizing agents known to oxidize Cr(III) to Cr(VI). In
addition, the kinetics of Cr(VI) reduction to Cr(III) is very fast, thereby outcompeting
reactions involving Cr(III) oxidation.
The JHU studies also determined that oxidizing agents, even in the unlikely event that they
might be present in environmentally relevant concentrations at DMT, are reduced by
constituents readily available in the sediments, namely, organic matter. Moreover, Cr(III) is
highly stable in sediments in Baltimore Harbor and only rigorous laboratory conditions will
catalyze the formation of Cr(VI) from Cr(III). These studies showed that Cr(VI) cannot
persist in the natural environment and that the reduction of Cr(VI) to Cr(III) is likely a
permanent process.
5.4.2 Hackensack River Chromium Investigations
The following section summarizes the results of studies conducted at chromium
contaminated sites in the lower Hackensack River, New Jersey. The lower Hackensack River
is a tidally influenced stretch of river with many characteristics that are similar to the
Patapsco River and the DMT site.
The study areas described below have been used for industrial and commercial purposes for
more than 100 years, including sodium dichromium manufacturing. It was common
practice in the mid-1900s to use COPR generated during chromate production as fill
material.
Geochemical Stability of Chromium in Sediments from the Lower Hackensack River, New
Jersey (Magar et al., 2008)
Magar et al. (2008) conducted sediment resuspension and oxidation experiments to
investigate the potential for release of Cr(III) or Cr(VI) and other chemicals of concern in
sediment to the water column in response to a sediment disturbance event at a chromium
contaminated site in the lower Hackensack River, NJ. The intertidal sediment exposure
experiment was designed to investigate potential aqueous release of Cr(III) or Cr(VI) from
intertidal surface sediments during low tide, the conditions under which sediments
experience the greatest level of oxygen exposure.
Results revealed no detectable concentrations of Cr(VI) and thus no measurable potential for
Cr(III) oxidation to Cr(VI) despite the fact that the experiments were designed to maximize
the oxidation potential in surface and suspended sediment samples due to exposure to
oxygen. The results of this study demonstrated that Cr(III) is stable and is expected to
remain geochemically stable in the study area sediments under ambient conditions, severe
weather conditions, and anthropogenic scouring events.

SECTION 5—QUARTERLY SAMPLING RESULTS
Chromium Geochemistry and Bioaccumulation in Sediments from the Lower Hackensack River,
New Jersey, U.S.A. (Martello et al., 2007)
Martello et al. (2007) measured total chromium and Cr(VI) in sediment and sediment pore
water in the lower Hackensack River, NJ to assess the relationship between sediment
geochemistry and chromium speciation, which in turn controls the mobility, bioavailability
and toxicity of chromium. Between 2003 and 2005, more than 100 surface sediment samples
(0 to 6 inches) were tested for total Cr, Cr(VI), AVS, Fe(II), Mn(II), ammonia, and organic
carbon. Sediment pore water samples were collected by centrifugation or in situ samplers
co-located with the collection of sediments. Concentrations of AVS and other geochemical
measurements indicated reducing conditions in the majority of sediment samples.
Chromium concentrations in whole tissues of polychaetes and clams exposed in the field or
in the laboratory showed no relationship with total chromium or Cr(VI) concentrations in
the sediment or pore water and no statistical differences in concentrations of chromium in
tissues of animals exposed to sediments from site versus reference locations. The results of
this study are consistent with the USEPA (2005a) EqP approach as well as sediment studies
conducted elsewhere indicating low chromium bioavailability in sediment under reducing
and even moderately oxidizing conditions.
Despite the occurrence of elevated concentrations of total chromium in sediments of the
lower Hackensack River, the results of this study indicate that little, if any of the chromium
is present as Cr(VI), and, therefore, risks associated with exposure to chromium are
particularly low. Further, Cr(VI) was not detected in any of the pore water samples. These
results are consistent with multiple geochemical indicators showing reducing conditions in
pore water and sediment. The low bioaccumulation of chromium to benthic invertebrates is
also consistent with these conclusions.
5.4.3 Similarities between Current DMT Study and Recent Chromium-Related
Studies
Each of the studies described above were conducted either in the Baltimore Harbor or in
river systems with similar characteristics. The findings from these chromium-related studies
reported in the peer reviewed literature have substantial similarities to DMT. Specifically,

Even at sites like DMT that contain high concentrations of chromium in sediment, the
chromium exists overwhelmingly in the trivalent form.

Regardless of high concentrations of total chromium in sediment, Cr(VI) was
consistently not detected in the pore water.

Like DMT, each of these studies has reported measurable concentrations of geochemical
constituents, such as AVS and Fe(II), that have been shown to reduce Cr(VI) to Cr(III).

Cr(III) was shown to be highly stable in each of the studies where Cr(III) oxidation
potential was tested.

Figure 5-2a. This figure shows that even the maximum concentration of dissolved Cr(III) in pore water
at DMT is not only below the current chronic NRWQC but is far below the hardness adjusted value
recommended by USEPA for sites that are estuarine or marine and even further below the acute
criterion. Figure 5-2b. This figure demonstrates the higher concentrations of dissolved Cr(III) in pore
water at the deeper water Transects D – H than in the shallow Transects A, B, C and J. Only Transect
D and E show a declining trend in dissolved Cr(III) concentrations with distance from the shoreline.

only below the current NRWQC but is far below the hardness adjusted value recommended by USEPA for sites that are

column would only be acutely exposed to dissolved chromium in surface water.

Figure 5-5a. This figure shows that in the few areas where SEM metals exceed AVS or AVS only slightly exceeds SEM, there is abundant
Fe(II) so that divalent metals are not biologically available for uptake by biota and there is sufficient reducing power in the sediments to insure
the existence of Cr(III) vs. Cr(VI). Figure 5-5b. This figure shows how changes in the water temperatures that occurs with season influences
salinity and dissolved oxygen concentrations which in turn influences concentrations of the key reductants AVS and Fe(II). Note that AVS and
Fe(II) are highest in the warmest months due to increases in microbial activity that deplete oxygen in the water column. Despite seasonal
fluctuations there is ample reducing power in DMT sediments to insure the stability of Cr(III).
