Subject: Capture Zone Analysis Technical Memorandum
Clariant Mount Holly East Facility
EPA ID# 001810 365
Dear Mr. Townsend:
On behalf of Clariant, Camp Dresser & McKee (COM) is pleased to provide this Capture Zone Analysis Technical Memorandum for the Clariant Mount Holly East Plant. This technical
memorandum presents the results of both a capture zone analysis and a fate and transport analysis, and includes site maps depicting estimated capture zones. The capture zone
analysis and the fate and transport analysis were performed in accordance with the Work
Plan dated October 20, 2004.
Project Background
The U.S. Environmental Protection Agency (EPA) prepared a Five-Year Review Report for the
Mount Holly East facility in September 2002. In this report, the EPA requested that the
groundwater system's capture zone efficiency be evaluated to assure that the extraction
system will meet the long-term protectiveness goals: In the September 2002 Five-Year Review
Report, the EPA noted the following: ·
■ Elevated levels of volatile organic compounds (VOCs) are present in monitoring wells
downgradient of the extraction wells.
■ Although VOC contamination is present downgradient of the extraction system, the
contamination has not impacted the surface waters of the Catawba River or cree_ks above
acceptable levels.
■ A capture zone analysis should be conducted on the extraction system in each of the CERCLA Areas (A through E) to determine if the current extraction system will meet the
long-term protectiveness goals.

■ Long-term protectiveness is defined within the five-year report as protecting adjacent
surface water bodies and achieving NPDES discharge requirements.
■ According to the five-year report, the capture zone analysis should determine if additional
extraction wells are required, or if increasing the current pumping rates of the existing
wells will address downgradient contamination.
■ A fate and transport analysis of the contamination downgradient of the extraction system
should be conducted as welL The fate and transport analysis will aid in answering
questions associated with the long-term effectiveness of the remedy.
■ The EPA believes that improved capture efficiency will aid in decreasing groundwater
contaminant concentrations.
■ The EPA did not set a milestone date for the completion of the capture zone analysis and
fate and transport analysis.
Capture Zone Analysis
A capture zone analysis was conducted for all recovery wells in all five CERCLA areas in both
the shallow /intermediate and deep zones. The shallow /intermediate zone consists primarily
of saprolite and partially weathered rock, while the deep zone consists of fractured rock. The
Capture Zone Module (MWCAP) of the EPA's Well Head Protection Area model (WHPA),
which delineates steady-state capture zones for recovery wells, was used to estimate capture
zones within each of the five CERCLA areas.
MWCAPMode/
MWCAP provides delineation of steady-state, time related, and hybrid capture zones for one
or more pumping wells in aquifers that are essentially homogenous with two-dimensional
steady-state flow. For this analysis, a number of simplifying assumptions were made, as
noted below. These various assumptions should be considered when interpreting the caph1re
zones delineated by MWCAP.
■ For all recovery wells, MW CAP was used to delineate steady-state capture zones. Time-
related or hybrid capture zones were not delineated. A steady-state groundwater flow
field was assumed.
■ The shallow /intermediate zone was considered as one homogeneous aquifer. The deep
(bedrock) zone was considered as a separate homogeneous aquifer. Available site data

characterizing the shallow /intermediate zone indicates that inhomogeneities are present.
The shallow /intermediate zone is primarily composed of residuum (saprolite)
transitioning into partially-weathered rock. In some areas, alluvium and a thin gravel
layer are also present in the shallow /intermediate zone. Inhomogeneities that may exist
are expected to have three primary effects on actual conditions versus the estimated
conditions. Preferential flow paths may exist that could cause the actual capture zone to
extend beyond the estimated zone along the path, assuming the preferential flow path is
hydraulically connected to the pumping well. If not connected, groundwater in the
preferential flow path may escape the pumping well. Inhomogeneities would also be
expected to result in capture zones that are more elliptical than estimated by the model.
Because of these limitations and assumptions, the estimated capture zones should be
considered approximate and the results applied conservatively.
■ The capture zone analysis does not consider the vertical flow of water within or between
the two zones.
■ Each well was specified to be operating without a lateral boundary (an aerally infinite
aquifer). MWCAP assumes that each recovery well operates independently of one
another. Therefore, physical processes such as well interference effects due to increased
drawdown are ignored. In addition, the effects of well interference due to overlapping
cones of depression are neglected. The effects of well interference are usually a larger
overall capture zone.
Despite the limitations and assumptions described above, the use of MWCAP is considered
an acceptable tool for the project objectives and delineating approximate capture zones for the
site recovery wells. A more sophisticated numerical solution, requiring an extensive
database, would be necessary to fully evaluate the impact of well interference, aquifer
inhomogeneity, and vertical flow between aquifers. For a full description of the MWCAP

MWCAP requires inputs to define the properties of the recovery wells and the aquifer
properties. Information on the recovery wells was obtained from the well installation logs
and from well pumping data. Data from previous site investigations and the literature
characterizing regional conditions were used to estimate aquifer properties. The MWCAP
input parameters are described below:

■ Discharge (Pumping Rates): Average recovery well flow rates from October 2003 to
August 2004 were used to determine the pumping rates for each of the 19 CERCLA wells.
A system-wide well redevelopment effort was completed in September of 2003, which
improved recovery rates in some wells. Average pumping rates measured after
September 2003 were assumed to be representative of the recovery system. The volume of
water pumped from each well is recorded during the bi-weekly pump maintenance
program. Table 1 presents the pumping data from 2001 through August 2004. Figure 1
presents the total flow from all 19 CERCLA wells from 2001 through August 2004. Table 2
presents the pumping data for each of the CERCLA wells from October 2003 through
August 2004. All tables and figures are included as Attachment A and B, respectively.
■ Hydraulic Gradient: The hydraulic gradient was calculated based on the groundwater
elevations measured in each CERCLA area during August 2004. The hydraulic gradient is
defined as the change in hydraulic head over a specified horizontal distance. The
hydraulic head calculations are provided as J\ttachment C.
■ Aquifer porosity: In each CERCLA area, aquifer porosity was estimated from literature
values including "Basic Elements of Ground-Water Hydrology with Reference to
Conditions in North Carolina", 1980, United States Geological Survey, by Ralph C. Heath.
Table 3 presents the recovery well and aquifer details including aquifer porosity. It
should be noted that steady-state capture zones are not dependent upon aquifer porosity.
Estimates of aquifer porosity were used in the fate and transport analysis, however.
■ Aquifer Thickness: For each recovery well, aquifer thickness is defined as the saturated
thickness of the aquifer and is estimated from existing boring logs. Aquifer thickness is
detennined as the thickness from the water table to the top of bedrock for wells screened
in the shallow and intermediate zones, and from the water table to the maximum screen
depth for wells screened in the deep zone. It should be noted that steady-state capture
zones are not dependent upon aquifer thickness; however, aquifer thickness was used to
calculate transmissivity.
■ Hydraulic Conductivity: Hydraulic conductivity was used to calculate transmissivity.
Hydraulic conductivity was estimated based on previous studies conducted in the
CERCLA areas including: "CERCLA Area C Spray Infiltration System and Remedial
Effectiveness Report", December 1999, COM; Appendix I, Ground-Water Model, Flow
Rate Estimations, and Solute Transport Model and Calculations, Remedial Investigation

Inc.; and "Supplemental Information for RCRA Ground-Water Recovery System".
■ Transmissivity: Transmissivity was calculated from the aquifer thickness and hydraulic
conductivity. A composite transmissivity of the aquifer in each CERCLA area was
calculated based on the presence of residuum, gravel, alluvium, partially-weathered rock,
and gravel layers within the aquifer.
■ Angle of Ambient Flow: This parameter aligns the capture zone to be parallel with the
groundwater flow direction. The angle of ambient flow was determined based on the
groundwater contour maps presented in the August 2004 Remedial Action Effectiveness
Report prepared by COM. The angle of ambient flow does not affect the dimensions of
the capture zone, only the capture zone alignment.
Based on a limited sensitivity analysis, pumping rate and transmissivity were found to have
the greatest impact on the capture zone size.
Results and Discussion
The results of the capture zone delineation for all five CERCLA areas are presented in Figures
2 through 5. MWCAP input and output are provided as Attachment D.
The recovery system in CERCLA Area A/B was designed to remove VOC contaminated
groundwater from the intermediate zone. Five wells (R-14, R-13, R-12, R-1 and R-2) are
located along an east-west axis between Area A/Band Long Creek, spanning approximately
750 feet. The recovery wells in CERCLA Areas A/Bare screened in the shallow and
intermediate zones. The MWCAP capture zones estimated in Figure 2 provide almost
complete coverage across approximately 1,500 feet. A gap of approximately 175 feet is noted
be_tween Arca A/B recovery well R-2 and Area C recovery well R-3. Contaminant
concentrations measured from monitoring wells CMW-2 and CMW-3, located approximately
halfway between the two recovery wells, have ranged from non-detect to approximately 5
parts per billion during recent sampling events. The data indicates that this gap between the
Areas A/Band C recovery wells is not a significant pathway for contaminant migration. The
effects of well interference may actually cause this area to be captured. The gap can be
eliminated by increasing the pumping rate of wells R-2 and R-3 by approximately 35 percent.
The pump, piping, and flow meter of R-12 will continue to be inspected to determine the
cause of the low pumping rate (0.0001 gpm). Wells R-1 and R-2 were briefly non-operational

for pump replacement in March and April of 2004, which likely lowered their average
pumping rate.
The recovery system in Area C consists of wells R-3 and R-4 screened in the shallow zone and
R-16, which recovers groundwater directly downgradient of the Area C spray infiltration
system in the former pit locations. As depicted in Figure 3, the recovery wells in CERCLA
Area Care estimated to provide groundwater capture across approximately 450 feet from
well OW-4 to well OW-6. Recovery Well R-16 provides a relatively small capture zone of less
than 50 feet. The current pumping rate of R-16 (0.68 gpm) is less than the design flow rate of
1.5gpm. ·
In December 2002, three additional recovery wells (R-17, R-18, and R-19) were installed in
CERCLA Area D to control groundwater flow in the gap between the RCRA well point
system and CERCLA Area D recovery wells. The CERCLA Area D recovery system now
consists of eight recovery wells screened in the shallow /intermediate (R-5, R-6, R-17, and R-
18) and deep zones (R-7, R-8, R-9, and R-19). As depicted in Figure 4, the recovery wells in
CERCLA Area Dare estimated to provide sufficient groundwater capture across Area D for
the deep zone. Two of the shallow/ intermediate wells (R-5 and R-6) provide minimal capture
zones due to the low pumping rates. Recovery well R-5 has an average pumping rate of 0.08
gpm and R-6 did not operate during the flow monitoring period of October 2003 through
August 2004. The cause of the low pumping rate of R-5 and inoperability of R-6 will be
explored during upcoming well operation and maintenance visits. The other two
shallow/ intermediate wells (R-17 and R-18) are modeled as having 150-foot and 40-foot
capture zones. The four deep wells (R-7, -8, -9, and -19) all provide capture zones at least 125
feet wide, and provide complete coverage across Area D.
The recovery wells in CERCLA Area E, which are screened in the intermediate zone, are
shown to provide groundwater caphtre across approximately 500 feet. Wells R-10 and R-11
both have average flow rates of 0.18 gpm, which contributes to a capture zone of
approximately 50 feet. Well R-15, with an average flow rate of 1.89 gpm, has a capture zone
that provides complete coverage across Area E.
It should be noted that the overlapping capture zones observed in each of the CERCLA areas
are a result of the MW CAP assumption that wells operate independently of one another. In
the two-dimensional flow field, capture zones would not overlap. More accurately, capture
zones would widen laterally in the opposite direction of the nearby recovery well, or
preferentially draw water from a different depth of the aquifer than the nearby well.

A water balance check was also conducted comparing the water recharge contribution from
the surface an,a of each of the capture zones to the total average pumping rate from each of
the recovery wells. The results of this water balance check support the results of the capture
zone modeling.
Capture Zone Modeling Conclusions
Capture zone analyses were conducted for recovery wells in CERCLA Areas (A through E) to
determine if the current extraction system will meet the long-term protectiveness goals.
Long-term protectiveness is defined within the five-year report as protecting adjacent surface
water bodies and achieving NPDES discharge requirements. The capture zone analysis
indicates that additional extraction wells are not required; however, increasing the current
pumping rates of recovery wells R-2 and R-3 may aid in further preventing downgradient
contaminate migration between Areas A/Band C.
Fate and Transport Analysis
A fate and transport analysis was conducted in each of the five CERCLA areas. The fate and
transport analysis focused on key contaminants that have been detected downgradient of the
recovery wells (e.g., 1,2-dichlorobenzene and chlorobenzene). Estimated travel times for the
major contaminant groups downgradient of the extraction system were calculated using
conservative dispersion and retardation factors from the literature. A general discussion of
the expected degree of natural attenuation occurring downgradient of the extraction system is
also included, based on limited water chemistry and hydrogeologic data collected during
previous investigations. The EPA has noted that contaminants have migrated downgradient
of the groundwater recovery systems, but the contamination has not impacted the surface
waters of the Catawba River or creeks above acceptable levels. The Surface Water and
Sediment Sampling Report, submitted to the HWS on September 17, 2002, also noted that
contamination has not impacted the surface waters and sediment of the Catawba River or
creeks above acceptable levels.
The fate and transport analysis contained on the following pages provides estimates of travel
times from the 19 recovery wells to Long Creek and Catawba River. Also included in the
analysis are estimated concentrations of the contaminants of concern at the creek and the
river. Table 4 presents the contaminants which were examined in this analysis. The fate and
transport analysis is based on the assumption that one or more recovery wells become
inoperable and thereby allow a slug of contamination to bypass the recovery system.

Transport Processes
Solutes move through an aquifer by three primary mechanisms: advection, dispersion, and
diffusion. The rate at which a solute moves through an aquifer is a function of the aquifer
media, the chemical and physical characteristics of the solute, and groundwater flow
conditions. As a contaminant moves through an aquifer, it undergoes natural attenuation
that reduce its mass, toxicity, mobility, and volume. This occurs via "non-destructive"
methods such as adsorption and dispersion, as well as "destructive methods"_via
biodegradation.
If a contaminant is conservative, it moves through the aquifer at a rate equal to the
groundwater velocity:
Kah
n, a,
where: K = hydraulic conductivity (ft/ d)
. nc = effective porosity
ah . . -= hydraulic gradient a,
In CERCLA Areas A, B, and C, without the influence of the recovery wells, groundwater
flows south west and eventually discharges to Long Creek. In CERCLA Areas D and E,
groundwater flows northwest and discharges to the Catawba River.
Using values of hydraulic conductivity and porosity previously derived from field studies,
the average linear groundwater velocity from each recovery well to it's respective discharge
area was calculated (Table 5). The hydraulic gradients were calculated assuming the recovery
wells were shut down and groundwater levels were recovered (i.e., no cones of depression).
To estimate travel time from the recovery wells to surface water bodies, the length of travel
along the groundwater flow path must be determined. For conservative contaminants, travel
time is equal to the length of the flow path divided by the average groundwater velocity.
However, many contaminants are not conservative and will adsorb onto particle surfaces as
they move through the aquifer, thereby altering, or retarding flow with groundwater.
Retardation is a function of both the aquifer and the contaminant species. Each contaminant
species has an affinity to sorb onto particle surfaces, described mathematically by a
distribution coefficient, Kd, which is a measure of the mass of solute adsorbed onto particles

to the concentration of dissolved solute. High Ka values indicate a high degree of retardation,
or a higher affinity of the contaminant to sorb onto particle surfaces. The retardation factor is
calculated as:
Where: p1, = bulk density of soil (g/cm3)
n = porosity
Ka = distribution coefficient (mL/ g)
The velocity of the contaminant is reduced by the retardation factor, or Ve= Vx/R, where v, is
the velocity at which the contaminant moves through the aquifer.
Organic compounds tend to sorb onto organic carbon within the aquifer and arc either
hydrophilic, that is, tend to remain in the dissolved phase, or are hydrophobic and have an
affinity for the solid phase. Sorption of organic solutes is therefore related to the amount of
organic carbon within an aquifer and the hydrophobicity of the chemical. The degree of
hydrophobicity is determined by the octanol-water partition coefficient. The octanol-water
partition coefficient is a measure of how the constituent partitions between octanol and water
when the two are mixed. A high octanol-water coefficient indicates that the chemical prefers
octanol, and is hydrophobic (will have a strong affinity for the solid phase). The distribution
coefficient for organic compounds is calculated as:
where: Koc = octanol-water partition coefficient (mL/ g)
foe = fraction of total organic carbon
Distribution coefficients for the organic contaminants of concern are listed in Table 6.
In addition to retardation, diffusion and mechanical dispersion influence contaminant fate
and transport through an aquifer. Diffusion, however, typically plays a much smaller role
than dispersion and in many cases can be negligible. Dispersion is caused as groundwater
moves through the porous media of an aquifer. Since the aquifer is filled with porous
sediment, there are several paths that groundwater (and contaminants) can take as it travels

through an aquifer. Therefore, a contaminant is spread out and become dispersed throughout
an aquifer segment. This process is illustrated in Figure 6. Mechanical dispersion is
calculated as follows (Fetter, 2001):
Mechanical dispersion = 0.L V x
where: a1. = longitudinal dynamic dispersivity (ft);
v, = average linear groundwater velocity (ft/ d)
and
a1. = 0.83(logL)2414
where: L = length of groundwater flow path (m; Fetter, 2001); or
a,_= 3.28x0.83[log(3~8)J414
where:
L = length of groundwater flow path (ft)
Mechanical dispersion combined with diffusion is termed hydrodynamic dispersion:
where: = longitudinal coefficient of hydrodynamic dispersion (ft2 / d);
0.LVx = mechanical dispersion (ft2/d);
D* = molecular diffusion (ft2 / d)
The longitudinal direction is the direction of groundwater flow. Transverse dispersion
(perpendicular to groundwater flow), Dr, is assumed to be 0.1D1. (Fetter, 2001). Dispersion
causes concentration to decrease downgradient of a source and become more spatially
distributed (Figure 7).
As mentioned above, in many instances, diffusion is insignificant compared to dispersion and
hydrodynamic dispersion is controlled by mechanical dispersion. Molecular diffusion is on
the order of 104 ft2/ d for the contaminants of concern (Table 4).

Travel Time to Surface Water and Concentration
As previously mentioned, the purpose of the fate and transport analysis was to determine the
time of travel for contamination to reach either Long Creek or the Catawba River should
contamination bypass the recovery wells.
Travel time for each contaminant of concern is determined from the retarded velocity
calculated from the retardation factors. An additional analysis was conducted toestimate the
approximate concentration of contaminants reaching either Long Creek or the Catawba River.
Assuming the recovery wells capture all or most of the contaminant plume, there is not a
continuous source of contaminant downgradient to the surface waters. Instead, it is assumed
that only portions or slugs of contamination are bypassing the recovery system, during
extended periods when the recovery wells are inoperable. To evaluate the concentration of
contaminant at the downgradient surface waters, the analytical solution of a slug of
contamination being injected into a two-dimensional flow field is used (Fetter, 1999):
C(x,y,t)
Where:
CA [ ((x-x )-v t)2
o ex o x
4m(D D j1i 2 p -4D I · I, T , l
Co = Initial concentration (ppb)
A = Ar~a over which spill or slug occurs (ft2)
DL = longitudinal hydrodynamic dispersion (ft2/ d)
Dr= transverse hydrodynamic dispersion (ft2/ d)
T = time (d)
Xo = starting position in the x-direction (ft)
yo = starting position in the y-direction (ft)
x = down gradient distance in x direction (ft)
y = down'gradient distance in x direction (ft)
For this an·alysis, the hypothetical contaminant slug area is based on the surface area of a slug
that would bypass a recovery well if the recovery well was non-operational for a one-month
period. The width of the hypothetical contaminant slug is based on the distance between
capture zones of the recovery wells surrounding the non-operational recovery well.

It should be noted that travel in the vertical direction is not considered and x is the direction
of groundwater flow. Therefore, the concentration at the solute frorit is approximated. For
this analysis, Xo and yo are set to zero (the position of each recovery welt) and since Long
Creek and the Catawba River are directly downgradient of the recovery welts, y is set to zero
as well. It should also be noted that concentrations calculated arc an approximation.
Although a slug is not being injected into the aquifer system, this is an attempt to represent a
slug of contamination that has bypassed the recovery system. It also assumes that the
contaminant occurs over the full thickness of the aquifer. These assumptions may not reflect
actual field conditions. The approach used here is intended to provide a conservative
approximation of contaminant concentrations.
Results and Discussion
Travel times and estimated concentrations at the stream from each of the 19 recovery welts
are listed in Tables 7 though 13. Due to the nature of the clay-rich saprolite, as well as the
moderate to low mobility of the contaminants, the travel time to reach either Long Creek or
the Catawba River is on the order of decades at most wells, except for Area D. Travel times in
Area Dare the quickest due in large part to the increased hydraulic conductivity in this area.
CERCLA Areas C and E have the longest travel time, due to the low permeability of the
formation and relatively long flow paths. The travel time in Arca E was based on data from
existing monitoring wells located several hundred feet from the Catawba River. It is likely
the hydraulic conductivity and/or hydraulic gradient differ near the river, which would
impact the calculated travel times in Area E potentially reducing the calculated travel times.
The estimated concentrations at the stream or river calculated from the fate and transport
modeling were compared against monitoring welts downgradient of the CERCLA areas. In
Area A/B, wells downgradient wells WQ-26 and WQ-261 were used for comparison. In Area
D, wells downgradient wells CMW-8 (shallow /intermediate zone) and WQ-33D (deep zone)
were used for comparison. The results estimated from the fate and transport modeling
compare favorably with the contaminant concentrations detected in the downgradient
monitoring .welts (taking into account the downgradient monitoring wells are not located on
the river bank or stream bank and thus additional dispersion and retardation is expected to
occur). In Area A/B, the 1,2-dichlorobenzene concentration detected in WQ-26, which is
· downgradient of R-1, is less than 1 ppb. The fate and transport modeling predicts a
concentration of 0.84 ppb for a plume not captured by R-1. In Area D, the 1,2-
dichlorobenzene concentration detecte.d in CMW-9, which is downgradient of R-7, is 657 ppb.
The fate and transport modeling predicts a concentration of 776 ppb at the Catawba River for
a plume not captured by R-7.

As noted in the EPA's Five-Year Review Report, although VOC contamination is present
downgradient of the extraction system, the contamination has not impacted the surface
waters of the Catawba River or creeks above acceptable levels. Impacted groundwater that
avoids the groundwater recovery system is anticipated to discharge to the stream or river for
an extended period of time due to dispersion (Figure 7). It also should be noted that the
estimated concentrations assume that the hydraulic gradient and groundwater velocity
remain constant.
Biodegradation is also not accounted for in these analyses. Biodegradation would further
decrease the concentrations of the contaminants as they reach the stream. Reductive
dechlorination of PCE may also be occurring in which PCE is broken down to vinyl chloride
and ethene (which is then further broken down to carbon dioxide, methane, and hydrogen
chloride). Although it is quite possible that biodegradation is occurring at the site, to date,
limited chemical data is available from the site to either support or refute the existence of
biodegradation as a natural attenuation mechanism. Therefore, it has not been included in
these analyses.

Recommendations
Specific recommendations as a result of this capture zone analysis and fate and transport
analysis include:
■ The only gap noted in the capture zone analysis is between R-2 and R-3, which is between
Areas A/Band C, at a distance of approximately 175 feet. This gap can be eliminated by
increasing the pumping rate of R-2 and R-3 by approximately 35 percent. R-2 and R-3 will
be inspected, and methods to increase their pumping rates will be considered.
■ The cause of the low flow rates in R-5 and R-6 will be explored during upcoming well
operation and maintenance visits.
■ The pump, piping, and flow meter of R-12 will continue to be inspected to determine the
cause of the low pumping rate.

■ Continue the bi-weekly pump operation and maintenance visits, which will assist in
keeping the groundwater recovery system operating as designed.
■ Continue to monitor the concentrations of contaminants downgradient of the recovery
wells to assist in locating future gaps in the groundwater recovery system.
■ Clariant is planning to conduct additional groundwater characterization within the next
few months to the northeast of Area E. The results of this capture zone analysis and fate
and transport analysis will be considered when reviewing these future groundwater
characterizations.
Please do not hesitate to call if you have any questions or need additional information.
Very tmly yours,

2. Aquifer thickness and hydraulic conductivity values listed above are based on the values noted in Appendix I, Ground-Water Model, Flow Rate Estimations, and Solute Transport Model and Calculations, Remedial Investigation Volume II, Soydeco Site,
Mt. Holly North Carolina, August 1987, Engineering-Science And Law Engineering Testing Company.
3. The above noted hydraulic conductivity value for the saprolite in Area C was based on slug tests performed by COM as noted in the "CERCLA Area C Spray Infiltration System and Remedial Effectiveness Report", December 1999, COM.
The hydraulic conductivity of bedrock for R-7, R-8, and R-9 is based on the hydraulic conductivity for SP-SC as presented in the report titled "Supplemental Information for RCRA Ground-Water Recovery System".
Hydraulic conductivity for bedrock aquifer at R-19 was taken from Report titled "Supplemental Information for RCRA Ground-Water Recovery S);Slem", Sandoz Mount Holly Plant, March 2, 1989, Law Environmental, Inc., and was based on the results
of slug tests performed at RCRA well SP-4C. CDM field geologists noted during installation of R-19 that th?' bedrock was highly fractured and very productive. Historically high pumping rates from this well reflect the fact that the well
is highly productive, relative to other site bedrock wells. The hydraulic conductivity of R-16 is based on slug tests performed in the PWR as reported in "CERCLA Area C Spray Infiltration System and Remedial Effectiveness Report",
December 1999, COM. The R-16 hydraulic conductivity results for PWR arc assumed to be indicative for Areas A/Band Arca E.
4. Aquifer thickness reported as thickness to the top of bedrock for wells screened in the shallow and intermediate zones, and to the maximum screen depth in the.deep zone.
Steady-state_ capture zones are not dependent upon porosity or aquifer thickness.
5. The porosity values listed above are based on the literature including "Basic Elements of Grmmd-Water Hydrology With Reference to Conditions in North Carolina", 1980, USGS, by Ralph C. Heath.
Steady-state capture zones are not dependent upon porosity or aquifer thickness .
.. The approximate screened interval is assumed to be 25 feel based on similar wells in CERCLA Area ~/B. Well installation records note that R-12 was installed to 108 feet below grade in an open rock interval.

Notes:
1 -The hydraulic conductivity va_lucs for Area D arc based on permeability testing conducted at SP-SC as presented in the report titled "Supplemental lnformalion for RCRA Gr~und-Watcr Recovery System"; the report titled "Supplemental Information for RCRA Ground-Water Recovery System", Sandoz Mount Holly Plant, March 2, 1989, Law
Environmental, Inc.; and the results of slug tests performed at RCRA well SP-4C. CDM field geologists noted during
installation of R-19 that the bedrock was highly fractured and very productive. Historically high pumping rates from
this well reflect the fact that the well is highly productive, relative to other site bedrock wells.
2 -The hydrogeologic parameters in Arca E are based on data from existing monitoring wells that are located several
hundred feet inland from the Catawba River. At this site, more productive alluvial sediments are often found near the
Catawba River. It is likely the hydraulic conductivity and/or hydraulic gradient differ near the river as compared to
near the existing monitoring wells, which would impact the calculated travel times in Area E potentially reducing the calculated travel times.

b. Wells R-17, R-18, and R-19 were not sampled in August 2004. The initial concentration values for R-17, R-18, and R-19 are from the October 2002 sampling event.

Recovery well R-16 was dry during the August 2004 sampling event. Therefore, the initial concentration data for R-16 was taken from the August 2002 sampling event.
c. The hypothetical contaminant slug area is based on the surface area of a slug that would bypass a recovery well if the recovery well was non-operational for a one-month period.

The length of the hypothetical contaminant slug area is based the contaminant velocity (in feet per day) multiplied by 30 days. The width of the hypothetical contaminant slug is based on the distance
between capture zones of the recovery wells surrounding the non-Operational recovery well.

d. The hydrogeologic parameters for Area E are based on data from existing monitoring wells that are located several hundred feet inland from the Catawba River. It is likely that the hydraulic conductivity and/or hydraulic gradient differ
near the river as compared to near the existing monitoring wells, which would impact the calculated travel times potentially reducing the travel times in Area E.
e. The surface water standard for 1,2-Dichlorobenzene is 488 ug/1; which is the standard for chlorinated benzenes that applies to surface water that is classified WS-IV as described in 15A NCAC 02B.0216.
The estimated concentration of the constituent at the stream interface (in this case the Catawba River or Long Creek) does not take into account dilution that would occur the moment the groundwater discharges to the surface water body.
Any surface water samples collected from the Catawba River or Long Creek would consist of groundwater mixed with surface water, and any contaminants in the groundwater would likely be greatly diluted.
The estimated concentratiOn should be considered conservative based on the assumptions described in the text.

d. The hydrogeologic parameters for Area E are based on data from existing monitoring wells that are located several hundred feet inland from the Catawba River. It is likely that the hydraulic conductivity and/ or hydraulic gradient differ
near the river as compared to near the existing monitoring wells, which would impact the calculated travel hmes potentially reducing the travel times in Area E.
e. The surface water standard for Ethylbenzene is 1,090 ug/1; which is the North Carolina Division of Water Quality Provisional Standard that applies to surface water that is classified Class C.
For this constituent, standards are not available in ISA NCAC 02B.0216.
The estimated concentration of the constituent at the stream interface (in this case the Catawba River or Long Creek) does not take into account dilution that would occur the moment the groundwater discharges to the surface water body.
Any surface water samples collected from the Catawba_River or Long Creek would consist of groundwater mixed with surface water, and any ~ontaminants in the groundwater would likely be greatly diluted.
The estimated concentration should be considered conservative based on the assumphons described in the text.

Notes:
a. Assume OT= 0.101,
b. Wells R-17, R-18, and R-19 were not sampled in August 2004. The initial concentration values for R-17, R-18, and R-19 are from the October 2002 sampling event.
Recovery well R-16 was dry during the August 2004 sampling event. Therefore, the initial concentration data for R-16 was taken from the August 2002 sampling event.
c. The hypothetical contaminant slug area is based on the surface area of a slug that would bypass a recovery well if the recovery well was non-operational for a one-month period.
The length of the hypothetical contaminant slug area is based the contaminant velocity (in feet per day) multiplied by 30 days. The width of the hypothetical contaminant slug is based on the distance
between capture zones of the recovery wells surrounding the non-operational recovery well.

d The hydrogeologic parameters for Area E are based on data from existing monitoring wells that are located several hundred feet inland from the Catawba River. It is likely that the hydraulic conductivity and/or hydraulic gradient differ
near the river as compared to near the existing monitoring wells, which would impact the calculated travel times potentially reducing the travel times in Area E.
e. The surface water standard for Xylene is 88.5 ug/1; which is the North Carolina Division of Water Quality Provisional Standard that applies to surface water that is classified Class C.
For this constituent, standards are not available in ISA NCAC 02B.0216.
The estimated concentration of the constituent at the stream interface (in this case the Catawba River or Long Creek) does not take into account dilution that would occur the moment the groundwater discharges to the surface water body.
Any surface water samples collected from the Catawba River or Long Creek would consist of groundwater mixed with surface water, and any contaminants in the groundwater would likely be greatly diluted.
The estimated concentration should be considered conservatiVe based on the assumptions described in the text.
