1.0 INTRODUCTION
The United States Environmental Protection Agency (USEPA), United States Department
of Justice, Beaunit Corporation, Burlington Industries, Inc. (Burlington), and El Paso
Natural Gas d/b/a El Paso Energy Corporation (El Paso) have entered into an agreement
(Consent Decree) for the performance of response work at the FCX-Statesville Superfund
Site (Site) Operable Unit 3 (OU3) in Statesville, North Carolina consistent with the National
Contingency Plan. 1bis response work includes performance of a Remedial Action (RA) for
soil and groundwater at the Site.
The RA is being performed by El Paso to implement the response actions selected for the
Site. The RA Work Plan ["Remedial Action Work Plan for Operable Unit Three (OU3),
FCX-Statesville Superfund Site, Statesville, North Carolina," Brown and Caldwell, July 2000]
provided a plan of action for completing the RA activities and presented a discussion of the
tasks to be performed. The RA Work Plan addressed the technical requirements of the
September 30, 1996 Record of Decision (ROD) issued by the USEPA and incorporated
work elements and deliverables previously specified in the Consent Decree, Statement of
Work, and in the approved Remedial Design (RD) Work Plan.
The RA for the treatment of groundwater and soil contamination at the Site is an air
sparging and soil vapor extraction (AS/SVE) system for the source area with monitored
natural attenuation (MNA) for areas downgradient of the AS/SVE system. An
observational approach has been incorporated into the RD and RA for implementation of
the AS/SVE system due to the heterogeneity of the soil at the Site as identified during the
AS/SVE Pilot Test that was conducted as part of the Pre-Design Investigation ("Pre-Design
Investigation Report for Operable Unit Three, FCX-Statesville Superfund Site, Statesville,
North Carolina" dated March 1999 by Brown and Caldwell). The observational approach
calls for a Phase I AS/SVE design, construction, and testing and allows for the design,
construction, and operation of a Phase II at a later time if determined appropriate. The
construction of the Phase I AS/SVE system has been completed and is documented in the
report entitled "Construction Completion Report for the Phase I Air Sparging and Soil
Vapor Extraction System, FCX-Statesville Superfund Site OU3, Statesville, North Carolina"

dated November 2000 by Brown and Caldwell. During the construction, an operational
acceptance test (OA 1) was conducted to check the installed AS/SVE system and collect
preliminary SVE performance data.
This report presents the results of the Phase I Performance Test of AS/SVE system which
was conducted according to the document entitled, "Performance Test Plan for the Phase I
Air Sparging and Soil Vapor Extraction System, FCX-Statesville Superfund Site OU3,
Statesville, North Carolina" dated November 2000 by Brown and Caldwell (hereafter
referred to as the Performance Test Plan). The preliminary SVE data collected during the
OAT is included within the Performance Test Plan. The Performance Test Report also
includes a discussion of recommended Phase II modifications to the Phase I system. The
rest of Section 1.0 presents background information for the Site, a description of the Phase I
AS/SVE system, the objectives of the Phase I Performance Test, an overview of the
Performance Test, and the report organization.
1.1 BACKGROUND INFORMATION
The following includes a brief description of the Site and the Site conditions.
1.1.1 Site Location and Description
The OU3 Site is located in Iredell County approximately 1.5 miles west of downtown
Statesville, North Carolina (see Figure 1-1). The Site consists of the soil,' groundwater,
sediment, and surface water contamination emanating from the textile plant property
currently owned by Burlington. The property is approximately 15 acres in size. Two large
buildings consisting of a warehouse (approximately 60,000 square feet in size) and a former
textile plant building (approximately 275,000 square feet in size) are located on the
Burlington property (see Figure 1-2).
Land immediately surrounding the Site is predominantly industrial with a variety of other
uses ranging from commercial to residential with associated school and church facilities.

Farther from the Site, rural land in the Statesville area is used for timber farming, grain crops
farming, and dairy farming.
The Site lies within the geologic belt known as the Blue Ridge-Inner Piedmont Belt, which is
situated in the Inner Piedmont Physiographic Province in western-central North Carolina.
This province is characterized as gently rolling slopes. The Blue Ridge-Inner Piedmont Belt
consists of metamorphic rocks including gneisses and schists. These rocks have weathered
to form a relatively thin overburden of saprolite, which is observed throughout the Site.
Groundwater at the Site is observed within the saprolite and underlying bedrock. Saprolite
forms the uppermost hydrogeologic unit. Groundwater occurs within the pore spaces of the
saprolite under water table conditions and is referred to as the shallow zone. Groundwater
within the fractured bedrock unit occurs under unconfined or semi-confined conditions and
is referred to as the intermediate zone. Site information indicates that the two units are in
hydraulic communication. Groundwater gradients observed on-Site indicate that
groundwater in the saprolite and bedrock appears to be flowing both to the north and to the
south from the textile plant. Figures 1-3 and 1-4 show potentiometric surface maps for the
shallow and intermediate zones, respectively.
As part of the planning for the Phase I Performance Test, geologic cross-sections were
developed for the source area using well log information from the installation of the SVE
extraction wells and monitoringprobes. Further information on the source area geology can
be found in Section 2 of the Performance Test Plan.
1.1.2 Site Conditions
Several media and constituents of interest are associated with OU3. The pnmary
constituents of interest include perchloroethylene (PCE), also called tetrachloroethene, and
other chlorinated hydrocarbons. The groundwater contains primarily PCE and other volatile
organic compounds (VOCs). On-Site soil contains primarily VOCs and to a lesser extent,
inorganics and polynuclear aromatic hydrocarbons (PAHs). Groundwater and soil
contamination are being remediated by AS/SVE with MNA for groundwater areas

downgradient of the AS/SVE system. Surface water and sediment associated with an
intermittent stream originating from a seep to the north of the Burlington textile plant also
contain some inorganic constituents, polychlorinated biphenyls (PCBs), and VOCs;
however, it was determined during the Remedial Investigation that the constituent
concentrations posed no risk and no remediation is required.
1.2 DESCRIPTION OF AS/SVE SYSTEM
The AS/SVE process that was installed during the Phase I construction consists of the
following components:
•
•
•
•
•
twenty-five triple-purpose wells
SVE system
air sparging system
Supervisory Control and Data Acquisition System (SCADA) system
security measures .
While each of the triple-purpose wells has a specific purpose now, the wells were designed
and constructed so that any of them can be used for SVE, air sparging, monitoring, or any
combination of the three. The aboveground piping and instrumentation have been installed
so that the wells can be used as follows for the Performance Test:
•
•
•
two wells for both air sparging and SVE
eight wells for SVE only
fifteen wells for monitoring probes .
The SVE system consists of piping from the SVE wells to a packaged blower system, a heat
exchanger, and two granular activated carbon (GAC) vessels. The piping includes a 6-inch
diameter common extraction header and 2-inch connecting pipe branches to each of the
wells selected for SVE. The SVE header and branch piping are fabricated from high-density
polyethylene (HDPE). The SVE blower system is skid-mounted and includes a liquid
separator, a particulate filter, provisions for bypass air, and two blowers piped to operate

individually or in parallel. The blowers operate to draw the soil gas out of the selected SVE
wells, through the heat exchanger, and through two GAC vessels that are operated in series
to capture organic vapors before the exhaust gas is discharged to the atmosphere. The heat
exchanger reduces the vapor temperature exiting the blowers to about 90°F or less, which
improves the GAC absorptive capacity. The GAC in the vessels can be exchanged when the
carbon in one vessel reaches its adsorptive capacity. The treated air is checked by an in-line
gas analyzer and subsequently exits the carbon vessels and the building through a vent pipe
that extends above the roof.
The air sparge system consists of an oil-free air compressor. The piping consists of 1-inch
HDPE, which is rated for compressed air. The piping runs from the air compressor to the
two wells selected for air sparging. The system forces air into groundwater through the
screened section of the air sparging wells. Solenoid valves, located in the air piping to each
of the air sparging wells, allow for the sparged air to be injected in pulses and at a desired
frequency and duration.
The SCADA system consists of instrumentation connected to the process p1p111g and
equipment. These instruments provide necessary operation data to the programmable logic
controller (PLC). The controls for the system are housed in two cabinets located in the
same area as the equipment. One cabinet houses the motor starters, PLC, hand switches,
alarm lights and other process electrical components. The other houses a computer that
enables an operator to visually monitor the system and control it. Data acquisition and
system operation can also be accomplished from a remote computer.
The AS/SVE process equipment and control cabinets are located within an equipment area,
which is secured inside an eight-foot tall chain-link fence with locking gates. The equipment
area is accessible from the outside using a key-operated, overhead coiling door. The
AS/SVE wells and adjacent piping throughout the plant are protected by bollards that are
set into the concrete floor and connected by chains.
The City of Statesville provides electric service to the AS/SVE system that is independent of
the building's main power. BellSouth provides telephone service using a telephone line from

a terminal located outside the building to allow remote access to the SeADA system via
modem.
1.3 OBJECTIVES OF PERFORMANCE TEST
Tbree primary objectives were identified for the Phase I Performance Test. These objectives
were:
•
•
•
assess the effectiveness of SVE
assess the effectiveness of air sparging
provide design and operating information to assess the need for Phase II
modifications.
To help assess the effectiveness of SVE, the testing was performed to collect the following
information:
•
•
•
mass of PeE removed from the vadose zone versus time
flow and radius of influence of SVE versus time
vapor phase PeE concentrations at the wells and monitoring probes versus time .
To help assess the effectiveness of air sparging in conjunction with SVE, the testing was
performed to collect the following information:
•
•
•
•
mass of PeE removed from the saturated zone versus time
flow and radius of influence of air sparging versus time
effectiveness of sparge air capture by SVE
affect, if any, of air sparging on MNA in the saturated zone .
The third objective of the Phase I Performance Test was to provide design information and
evaluate the need for Phase II modifications. The overall objective of AS/SVE is to remove
voe mass from the Site source area. The second part of the remedy is MNA outside the
source area as a means to remove VOe mass from the down gradient saturated zone. The

Phase I Performance Test data have been evaluated to determine if any changes to the
system are recommended to address the source area VOCs.
1.4 OVERVIEW OF PERFORMANCE TEST
The Phase I Performance Test involved operation of the SVE system usmg the ten
extraction wells for approximately two months followed by two weeks of operation of
AS/SVE. After the two weeks of AS/SVE operation, SVE was continued for
approximately one additional month using the ten extraction wells. The Performance Test
operation of SVE was from February 1 to May 15, 2001, or 3.5 months. Groundwater
samples were collected before, during; and after the test to monitor. any changes in VOCs or
selected natural attenuation parameters. Vapor samples were collected and analyzed at five
different times during the Performance Test: shortly after startup, during SVE only,
immediately prior to air sparging, during air sparging, and after the last month of SVE.
These vapor samples were collected at each extraction well, at the blower inlet, and between
the GAC vessels to monitor changes in VOC concentrations and the mass removed. · Vapor
samples were also collected from selected monitoring probes before and after SVE. A
helium tracer test was conducted during air sparging to check the effectiveness of capture of
sparged air by the SVE system. During the operation of the SVE and air sparging systems,
both remote and on-Site monitoring of the process was performed to maintain the system
and monitor the overall system performance. On July 7, 2001, after completion of the
Performance Test site work, the SVE system was restarted as a proactive measure to begin
VOC removal from the source area while the Performance Test Report was being prepared.

2.0 DESCRIPTION OF PHASE I PERFORMANCE TEST
This section describes the Performance Test of the Phase I AS/SVE system. The
Performance Test consisted of operating the SVE system for a defined period of time
followed by operating the combined AS/SVE system for a brief period of time. Figure 2-1
shows the locations of the two AS/SVE wells, the eight SVE wells, and the 15 ~onitoring
probes that were installed as part of the Phase I AS/SVE system. Selected data were
collected before, during, and after operation of the process to aid in the performance
evaluation. Figure 2-2 provides a timeline for the testing which includes the operation
schedule for SVE and AS/SVE and the work activities conducted before, during, and after
operation of the system. The work activities were as follows:
•
•
•
•
•
•
Instrumentation calibration (before operation)
Source area groundwater sampling and water level measurements
(before, during, and after operation)
Permeability testing at monitoring probes (before operation)
Vapor sampling (before and during operation)
Monitoring of system during operation (on-site and remote)
Helium tracer testing (during operation) .
As shown in the schedule (Figure 2-2), some of these work activities were conducted
simultaneously. These activities are described in the following sections. Brown and Caldwell
conducted the on-Site work in accordance with the Site-specific health and safety plan
(HASP) entitled "Health and Safety Plan for Remedial Action of Operable Unit Three,
FCX-Statesville Superfund Site" dated May 2000 by Brown and Caldwell. This HASP was
also used during the Phase I rnnstruction.

2.1 INSTRUMENTATION CALIBRATION
Prior to system start-up, the instrumentation was calibrated or calibration checks were
performed according to the Operations and Maintenance (O&M) Manual for the system
("Operation and Maintenance Manual for the Air Sparging and Soil Vapor Extraction
System, FCX-Statesville Superfund Site, Statesville, North Carolina" dated November 2000
by Brown and Caldwell). The instruments that were calibrated included pressure gages and
transmitters as well as vacuum gages and transmitters. Some of these pressure gages and
transmitters measure differential pressure at pitot tubes. Expert Services International, LLC
of Charlotte, North Carolina was subcontracted to perform the calibration work. Thirty-six
instruments were calibrated by adjusting the instrument zeros and spans. Five instruments
(PE0101, PE0102, FE0202, FE0207, and FE0401) were found to be defective. These five
instruments were replaced and calibrated on March 30, 2001.
Two PCK gas monitors were installed on the original SVE system; one at the inlet to the
SVE blower package and the second at the midpoint between the two GAC vessels. The
two gas monitors were factory calibrated. It was determined that the gas monitor located at
the inlet to the SVE blower package was not operating correctly, so it was removed and
returned to the vendor. After a reevaluation of the vapor sampling conditions with the
vendor, it was decided that the monitor was not going to work at that location so the gas
monitor was not replaced. This did not impact the test since periodic vapor sampling was
performed at this location during the Performance Test.
2.2 SOURCE AREA GROUNDWATER SAMPLING
Source area groundwater sampling was conducted before, during, and after the Phase I
Performance Test to monitor the affects of AS/SVE on the groundwater in the source area.
Four groundwater-sampling events were performed on the dates shown in Figure 2-2. Both
the extraction wells and monitoring probes were sampled. Table 2-1 shows which
wells/probes were sampled in each event and which parameters were measured or analyzed
for. For sampling Event 2, the selection of wells to be sampled was based on the results of
the OAT and the relationship between the sampling intervals and the lithology at that

sampling location and depth. Wells screened substantially below the water table in regions
of apparent low permeability were not considered for sampling Event 2. Sampling Event 1
was performed prior to SVE operation. Groundwater sampling Events 2 and 3 were
performed just prior to and just after air sparging, respectively. Sampling Event 4 was
performed approximately two months after air sparging was discontinued. The wells/probes
for sampling Events 1 and 4 were selected as those most likely to show overall impact due to
AS/SVE. Sampling Event 2 has been used to determine if SVE has an effect on
groundwater quality. Sampling Event 3 is• most critical and has been used to determine the
impact of air sparging on VOC concentrations and natural attenuation in the groundwater.
Twenty-four wells and monitoring probes were sampled during Event 3. Event 4 was used
to check for rebound after AS/SVE shutdown.
· Groundwater samples were collected following the sampling procedures in the Quality
Assurance Project Plan (QAPP). Analysis of the samples either in the field or by the
laboratory was according to methods and procedures · consistent with the ongoing
semiannual MNA sampling. ELAB, Inc. (formerly Eckenfelder Laboratory, LLC)
performed the analyses. Quality Assurance/Quality Control (QA/QC) samples were
collected and analyzed for each sampling event according to the QAPP and using the
QA/QC sampling frequency indicated in the O&M Manual. The VOC data were validated
by Environmental Data Services, Ltd. (EDS), a third party that specializes in analytical data
validation. Groundwater level measurements were made during each sampling event and
during the air sparging operations.
2.3 PNEUMATIC PERMEABILITY TESTING
Prior to start-up of the SVE system, pneumatic permeability tests of the vadose zone were
conducted at each of the 15 monitoring probes. Since one of the objectives of the Phase I
Performance Test was to determine if the Phase I AS/SVE system is adequate or if Phase II
design and construction is warranted, one important piece of information is the pneumatic
permeability at locations other than the existing SVE wells. The monitoring probes were
constructed identically to the extraction wells with the exception of the piping and
instrumentation that connect the extraction wells to the AS/SVE system. One potential use

of a monitoring probe in Phase II, if warranted, is to convert the probe to an extraction well.
Prior to making that decision, it is important to know the pneumatic permeability of the
probes, especially since the preliminary performance data from the OAT showed that there
was significant variation in SVE flow at the different SVE wells due to heterogeneity at the
Site.
The pneumatic permeability testing was conducted by using the existing SVE blower system
to extract air from each of the monitoring probes. A length of PVC pipe that was fitted with
a pitot tube with a differential pressure gage, a thermocouple, a vacuum gage, and a sample
port, was attached to a monitoring probe. A flexible 2-inch PVC vacuum hose was
connected from the PVC piping to one of the spare flange locations on the main 6-inch
SVE header pipe. The permeability test was conducted at each monitoring probe by setting
the vacuum at the blower at three different levels and measuring the resulting flow rate at
each vacuum setting. At the highest vacuum setting, the neighboring extraction wells and
monitoring probes were checked for vacuum influence. Vapor samples for VOC analysis
were also collected from selected monitoring probes during the permeability test as
described in Section 2.4.
2.4 VAPOR SAMPLING
Five vapor sampling events were conducted as part of the Phase I Performance Test. These
events are shown in Figure 2-2. Samples from selected monitoring probes, SVE wells, and
SVE process locations were collected in Tedlar bags following the same procedure and
QA/QC sampling type and frequency as was used during the OAT (see Section 2.3 of the
Performance Test Plan). The Tedlar bag samples were analyzed for VOCs by ELAB, Inc.
using USEPA method 8260.
In addition to vapor samples collected in Tedlar bags for laboratory analysis, vapors were
also evaluated on-Site using Draeger tubes specific for PCE. This evaluation was performed
by using the same sampling pump that was used to collect the Tedlar bag samples to draw
vapors from a sampling port through tubing sized appropriately for the Draeger tubes. The
vapors were collected in the Draeger tube using a Draeger accuro bellows pump according
P: \PROJ\ 18895\ 18895.019\S02doc . 2-4

to the manufacturer's instructions. Concentrations of PCE (and other VOCs that also are
indicated by the tube) were read from the tube according to the color indications on the
graduated scale on the side of the tube. Two different types of Draeger tubes specific to
PCE were used so that the anticipated range of VOC concentrations could be measured: 2
to 40 ppm and 10 to 500 ppm. The tube with the range of 2 to 40 ppm could also be used
to measure a range of 20 to 300 ppm. As laboratory analytical data were available, the
Draeger tube results were compared with the laboratory data to check for correlation
between the PCE results.
Vapor sampling Event 1 consisted of sampling the monitoring probes, the extraction wells,
the SVE blower inlet, and the midpoint between the two GAC vessels. Nine of the
monitoring probes, primarily along the perimeter of the source area, were sampled for VOCs
during the permeability testing just prior to the start-up of the SVE system. These probes
were MP-1, MP-3, MP-4, MP-7, MP-8, MP-9, MP-12, MP-13, and MP-14. The SVE system
was operated for a short time period long enough to collect vapor samples from each
extraction well, the SVE blower inlet, and the midpoint between the two GAC vessels. The
following day, the SVE system was started for continuous operation for the duration of the
Performance Test. After approximately one month of SVE operation, sampling Event 2
was conducted to collect vapor samples from the extraction wells, the SVE blower inlet, and
the midpoint between the two GAC vessels. The same locations were sampled during
sampling Event 3 Gust prior to the initiation of air sparging) and during sampling Event 4
(during air sparging). Sampling Event 5 was conducted at the end of SVE operation
approximately one month after air sparging. For sampling Event 5, the extraction wells, the
SVE blower inlet, and the midpoint between the two GAC vessels were sampled as well as
the same monitoring probes that were sampled in sampling Event 1.
2.5 MONITORING OF THE AS/SVE SYSTEM
Routine monitoring.of the AS/SVE system was performed while the system was operating.
On-Site monitoring of the system was performed during the on-Site vapor sampling events,
which are shown on Figure 2-2. These monitoring visits were used to inspect the SVE
system, make adjustments if required, and to collect vapor samples as scheduled. The

system data were checked to monitor system performance and allow for response to any
system operating problems that might occur. Adjustments to system parameters such as
applied vacuum were performed as necessary during these events. Personnel were on-Site
daily monitoring the AS/SVE system during the air sparging system operation.
Remote off-Site monitoring was performed when the system was not manned. The remote-
dial feature of the SCADA system allows monitoring and control from a remote computer
location. The remote monitoring was performed during the operation of SVE; personnel
were on Site during operation of air sparging. The system data were checked two to three
times per week to check system performance and allow for response to any system operating
problems that might occur.
2.6 AIR SPARGING WITH HELIUM TRACER TESTING
The air-sparging test was conducted over a nine-day period and SVE was performed
continuously during air sparging, as well as for approximately one month after the air
sparging was discontinued. During operation of the air sparging system, helium tracer tests
were performed with each of the two air sparging wells. The purpose of the helium tracer
test was to track (or trace) the transport of sparged air from the groundwater sparge point to
other groundwater monitoring points and to the vadose zone. This testing was intended to
help determine the transport directions and the overall success of capture of sparged air by
the SVE system .. The helium tracer test was conducted by injecting a measured quantity of
helium into the sparge air stream for a period of time. A portable helium gas monitor was
used to check for the presence of helium at the SVE extraction wells and at the monitoring
probes. Both helium concentration and time of travel were recorded as the data were
collected.
On April 4, 2001, the helium tracer test was performed at EW-1/SW-1 with no sparging at
EW-2/SW-2. Air sparging was performed at SW-1 for a total of approximately 8.9 hours.
Approximately 0.7 hours after air sparging was begun, helium flow was initiated and
approximately 210 scf of helium was injected into sparge well SW-1 over· a period of
approximately 1.5 hours. Monitoring for helium was performed systematic~lly at the

extraction wells and monitoring probes during and following the helium injection period.
The helium monitoring was performed with a Mark Model 9821 helium detector with a
detection range of 0.01 % to 100% helium. The helium monitoring at the extraction wells
and monitoring probes was continued throughout the following day. Each well or probe
was checked periodically for helium during the test; none were monitored continuously.
After the helium concentrations had dissipated in the vadose zone, the helium test was
repeated for EW-2/SW-2 on April 6, 2001, with no sparging a~ EW-1/SW-1. Sparging was
performed at SW-2 for approximately 8 hours. Approximately 210 scf of helium was
injected over a time period of approximately 4 hours.
After the second helium test was completed, both sparge wells were .run. simultaneously to
check on the overall effect on the system. The vacuum at each monitoring probe was
checked during this time. Both sparge wells were operated for approximately three days
(75 hours) and then turned off with SVE still operating. Helium monitoring at the
extraction wells and monitoring probes was also performed during these three days to check
for residual helium in the system. ·The air injection rate at each of the two sparge wells was
set at approximately 1 scfm for the first day, 2 scfm the second day, and 4 scfm for the final
day (total combined flows were 2, 4, and 8 scfm, respectively). During the last hour of air
sparging, the flow rates were increased in steps to approximately 10 scfm flow at each well in
order to obtain flow/pressure data for each of the sparge wells. As described in Section 2.4,
vapor samples were collected from the extraction wells, the SVE blower inlet, and the
midpoint between the two GAC vessels during air sparging with both sparge wells and while
SVE was operating.
During the air sparging testing, a total of approximately 24,000 scf of air was injected into
SW-1 and SW-2 combined. The SVE system was shut down approximately one month after
air sparging was discontinued. Two months after the air sparging, groundwater samples
were collected as described in Section 2.2.

3.0 RESULTS OF PHASE I PERFORMANCE TEST
This section of the report presents the results of the Phase I Performance test and includes
discussions of pneumatic permeability, SVE performance, air sparging performance,
groundwater sampling in the source area, and vapor sampling in the source area.
' Conclusions and recommendations based on these results are presented in Section 4.0.
3.1 PNEUMATIC PERMEABILITY RESULTS
Pneumatic permeability testing of the extraction wells and monitoring probes was performed
by collecting vacuum and flow data from each well and probe location. The extraction wells
had been tested during the OAT using vacuum and flow data collected by the SCADA
system. They were tested again at the start of the Phase I Performance test using magnehelic
gages at the well/ probe locations to measure vacuum and flow directly. The run time for
each well was dependent on the actual flow achieved and the time that was required to
collect the performance data from each well. Each monitoring probe was operated
temporarily as an extraction well using a two-inch flexible PVC hose and PVC piping that
was attached from the probe to the SVE system extraction header. In this way, vacuum and
flow data were collected at the monitoring probes.
Figures 3-1 and 3-2 present graphs showing the vacuum-flow relationship for each of the
extraction wells and monitoring probes. These figures show the measured relationship
between applied vacuum at the well or probe [reported as inches water column (in.W.C.)]
and the resulting extraction air flow rates [reported as standard cubic feet per minute (scfm)].
The extraction well standard flow rates were calculated using temperature readings from the
SCADA operator display and vacuum and flciw data from magnehelic gages located at the
extraction wells. The monitoring probe flow rates (at standard temperature and pressure)
were calculated using temperature data from a thermocouple and vacuum and flow data
from magnehelic gages located at the monitoring probes. Due to the heterogeneity of the
Site geology, there is a range of flow rates that can be achieved with the same applied
vacuum, depending on the location of the extraction well or monitoring probe. For

example, for an applied vacuum of approximately 65 in.W.C., the following flow rates were
measured at the different well and monitoring probe locations:.

20 to 22 scfm for EW-2 .
16 to 18 scfm for EW-5, EW-8 and EW-9 .
14 to 16 scfm for EW-1, EW-4, and MP-13 .
12 to 14 scfm for EW-3, MP-9, and MP-10 .
10 to 12 scfm for EW-10, MP-2, MP-5, MP-6, MP-11, and MP-15 .
8 to 10 scfm for MP-1, MP-4, and MP-12 .
6 to 8 scfm for MP-3, MP-7, MP-8, and MP-14 .
0 scfm (no measured flow) for EW-6 and EW-7 .
The vacuum-flow graphs in Figure 3-1 and 3-2 are based upon data collected .on January 31
and February 1, 2001 at the beginning of the SVE operations. Flow rates of the SVE wells
were monitored periodically throughout the Performance Test and remained fairly constant.
Data from the SCADA system indicated that EW-7 probably bad some flow, although low.
Direct magnehelic data collected indicated a low flow from EW-6 also. By way of
comparison, the SVE flow rate measured during the AS/SVE pilot test (at the pilot test
extraction well located outside the building east of EW-10) was approximately 20 scfm for a
vacuum of 65 in.W.C. Only the SVE well EW-2 achieved a flow rate this high; the other
wells and monitoring probes were lower. The SVE system design capacity was based on the
AS/SVE pilot test data, and as such, the SVE system design capacity exceeds the actual
combined SVE flow rate from the 10 operating SVE wells.
3.2 SVE RESULTS
The SVE results include a discussion of the system performance, the SVE area of influence,
and an evaluation of the SVE performance data.

3.2.1 SVE System Performance
The SVE system was successfully operated for 3.5 months during the Phase I Performance
Test. Only one of the two redundant SVE blowers was operated during the test; the second
blower was available but the extra capacity was not needed. The isolation valves to the ten
SVE wells were maintained in the full open position for the SVE test period. The air bleed-
in valve, located at the packaged blower system, was used to adjust and control the SVE
system vacuum. The SVE system responses to vacuum adjustments were rapid and stable
over time. Llttle or no drift in vacuum or flow rate occurred after the air bleed-in valve was
set. The vacuum measured at the extraction wells was essentially the same as the vacuum at
the inlet to the SVE blower system, indicating that there was no measurable pressure drop in
the SVE piping and headers at the extraction flow rates achieved. The blower inlet vacuum
was maintained between 55 and 65 in.W.C., which corresponded to an SVE flow rate of
approximately 50 to 70 scfm. The blower system is capable of operating at a vacuum of
75 in.W.C. or higher; however, during unattended operation, the vacuum was maintained
between 55 and 65 in.W.C. as a conservative measure.
The SCADA system provided easy and reliable monitoring and control of the AS/SVE
process both locally and remotely. On two occasions when the system was not manned
during the 3.5-month operating period, the SVE blower system automatically shut down.
The remote dial-up feature of the SCADA system was used to restart the blower from the
Brown and Caldwell offices in Nashville, Tennessee. It is theorized that the shutdowns were
caused by power interruptions from the City of Statesville.
The air-to-air heat exchanger on the discharge of the blower was operated for the duration
of the SVE system operation. The vapor temperature exiting the blower and entering the
air-to-air heat exchanger ranged from about 140°F to 170°F during the SVE Performance
Test period. The temperature of the vapor exiting the first GAC vessel ranged from about
60°F to 85°F while the ambient temperature in the AS/SVE equipment area ranged from
about 50°F to 80°F. Thus the air-to-air heat exchanger effectively cools the vapors from the
blower so that the vapor temperature after the first GAC vessel is approximately 5°F to

10°F greater than the ambient temperatw:e. If the ambient temperatw:e in the equipment
area exceeds 90°F during the hotter summer months, the temperatw:e exiting the GAC
could exceed 100°F, which is the desired maximum operating tcmperatw:e of the GAC.
Although the GAC vessels can be operated at higher temperatw:es, the VOC loading
efficiency decreases. If the equipment area temperatw:e exceeds 90°F, it may be appropriate_
to tw:n off the SVE system in order to prevent the excessive consumption of the GAC.
Early in the Performance Test when the ambient temperatw:e inside the building was cooler
(February and March 2001), condensate accumulated in the four condensation drip. traps
(DT1, DT2, DT3, and DT4), the SVE header piping, and the moisture separator at the SVE
blower system. Condensate was drained from the drip traps, which also removed
condensate from the header piping. Condensate was drained from the system on February
9, March 2, and March 30, 2001. A cumulative total of 50.4 gallons of condensate was
removed and placed in a carboy (a 275-gallon plastic container encased in a protective metal
basket) for appropriate disposal. A summary of the volume removed is as follows:
• DT1: 23.5 gallons
• DT2: 5.8 gallons
• DT3: 1.3 gallons
• DT4: 18.8 gallons
• Moistw:e Separator: 1.0 gallons
• Total Condensate: 50.4 gallons
As the data indicate, the majority of the condensate collected in the drip traps (and SVE
header piping) before it could flow to and be collected in the moistw:e separator at the SVE
blower package. Only about 2% of the total condensate collected had accumulated in the
moisture separator.
The two GAC vessels were operated in series. Once breakthrough of the first GAC vessel
was confirmed by sampling and laboratory analysis, the vapor-phase carbon was changed out

3.2.2 SVE Area of Influence
Figure 3-3 presents an isobar map that shows the measured vacuum data collected at the
extraction wells and monitoring probes during the Performance Test after approximately
two months of SVE operation with all of the ten extraction wells operating. These data give
an indication of the area of influence in the vadose zone from the SVE system. The SVE
area of influence, as indicated by soil vacuum measurements of .0.1 in.W.C. or greater,
appears to extend between the SVE wells and beyond the monitoring probes with the
exception of MP-1, MP-3, MP-8, and MP-14, which are located some distance away from
the SVE wells.
3.2.3 Evaluation of SVE Performance Data
The vacuum and flow data obtained for each SVE well and each monitoring probe indicate
heterogeneous pneumatic permeabilities within the vadose zone. This heterogeneity was
previously identified during the OAT that was conducted in 2000 and during the AS/SVE
pilot test that was conducted as part of the pre-design investigation in 1998. The vacuum
data in Figure 3-3 at the perimeter monitoring probes show the heterogeneity of SVE at the
site. The perimeter monitoring probes (MP-1, MP-3, MP-7, MP-8, MP-13, and MP-14) are
located at about 70 to 100 feet from the nearest SVE well. The vacuum influence on these
perimeter wells ranges from 0.00 in.W.C. at MP-8 and MP-14 to 0.65 in.W.C. at MP-13
indicating the heterogeneous pneumatic permeabilities. For the monitoring probes located
around the perimeter of the SVE well area, there appears to be some direct correlation
between the vacuum observed during SVE at those monitoring probes and the vapor flow
rate achieved during the pneumatic permeability testing (i.e., generally locations with low
vacuum during SVE had low flow rates during the pneumatic permeability test and locations
with higher vacuum during SVE had higher flow rates during the pneumatic permeability
test).

Although the instrumentation was calibrated during construction, it 1s appropriate to
periodically calibrate them as part of the routine system O&M. The routine system O&M is
provided in the document entitled "O&M Manual for the Air Sparging and Soil Vapor
Extraction System, FCX-Statesville Superfund Site OU3, Statesville, North Carolina" dated
November 2000.
3.3 AIR SPARGING RESULTS
The au sparging results include a discussion of the system performance, the area of
influence, and an evaluation of the air sparging performance data.
3.3.1 Air Sparging Performance Data
The air sparging compressor, solenoid shutoff valves, and associated controls and
instrumentation performed as designed. The two designated sparging wells, EW-1/SW-1
and EW-2/SW-2, had favorable flow-pressure characteristics, allowing continuous air flow
rates of up to 10 scfm per well at a delivery pressure of approximately 15 psig. Figure 3-4
presents the flow-pressure relationship for each of the two air sparging wells.
One way to measure the area of influence from-air sparging is to note the change in vacuum
at the various monitoring probes and extraction wells caused by air sparging. In Section
3.2.2, tl1e SVE area of influence in the vadose zone was discussed and vacuum data were
presented showing that area of influence. When air sparging was performed, the vacuums in
the vadose zone at the extraction wells and monitoring probes were measured again. These
data were compared to the vacuum data measured during SVE only. Figure 3-5 shows the
change in measured vacuum as a result of air sparging with both sparge wells (SW-1 and
SW-2) operating simultaneously. The region within the O vacuum isobar exhibited a
decrease in vacuum, which is attribu_ted to the introduction of air at the two sparging wells.
The vacuum decreased, indicating an influence due to air sparging, at 19 of the
25 monitoring wells and probes. Only the outermost monitoring probes (MP-1, MP-3,
MP-7, MP-8, and MP-14) and one extraction well (EW-5) showed no influence (vacuum
decrease) during air sparging.

3.3.2 Helium Tracer Test Results
The extraction wells and monitoring probes were systematically monitored for helium during
and following injection of helium at the two air sparging wells SW-1 and SW-2. The wells
screened in the vadose zone and the wells screened in the shallow groundwater within the
source area were monitored for helium. Helium monitoring in the shallow groundwater
wells was performed in the well headspace approximately one foot above the groundwater
elevation. The helium detector was moved from well to well and as such, continuous
monitoring of the individual wells was not possible. After initial evaluation of the helium
test results, it was determined that, because each well was not monitored continuously, the
data for the two tests (helium injection at SW-1 and helium injection at SW-2) would be
combined to best show the overall effect of air sparging within the source area. Therefore,
this section presents data for both tests as one test.
Figure 3-6 presents the helium results from vapors monitored in the headspace of the
shallow groundwater wells within the source area. The isoconcentration lines illustrate the
heterogeneity of helium transport within the shallow groundwater. The results shown on
Figure 3-6 are the highest results measured during the air sparging test without regard to
when they were measured and which air sparging well the helium might have come from.
Helium was detected in two of the perimeter monitoring probes: MP-1 to the east, and
MP-7 to the south, no helium was detected in several of the monitoring probes and SVE-
well locations that are closer to the air sparging wells.
Figure 3-7 presents the helium results from the source area wells within the vadose zone.
The results shown on Figure 3-7 are the highest results measured during the air sparging test
without regard to when they were measured and which air sparging well the helium might
have come from. As with the shallow groundwater, the helium transport within the vadose
zone is heterogeneous and is not uniform with respect to the air sparging injection points.
Helium was detected at three of the perimeter monitoring probes (MP-1, MP-7, and MP-13),
while none was detected in several of the probes and wells that are much closer to the

sparging wells. Because each location was not monitored continuously, helium could have
been present at a particular time but absent at the time the location was monitored.
3.3.3 Evaluation of Air Sparging Performance Data
The pressure and flow data obtained for each air sparging well indicate that there is adequate
pneumatic permeability within the saturated zone to perform air sparging. The helium tracer
test confirmed the heterogeneity that exists within the saturated zone and vadose zone that
was previously identified during the OAT and in the AS/SVE pilot test. Comparison of the
helium tracer test isoconcentration maps (Figures 3-6 and 3-7) with the SVE vacuum isobar
map (Figure 3-3) indicates that most of the sparged air was likely captured by SVE. At three
of the perimeter monitoring probes (MP-1, MP-7, and MP-13) .and one of the SVE wells
(EW-10), SVE capture of the sparged air may not have been complete under the conditions
of the Performance Test. Due to the heterogeneous nature of the subsurface, there may be
other areas in which the sparge air was not completely capt:med by SVE.
3.4 GROUNDWATER SAMPLING RESULTS
Table 3-1 presents the source area groundwater sampling results for PCE and selected
natural attenuation daughter products of PCE, which include TCE, cis-1,2-DCE, and vinyl
chloride. In addition, the table contains results for other VOCs and for field natural
attenuation parameters. Table 3-1 presents results from groundwater sampling during
construction and from the four sampling events that were part of the Phase I Performance
Test. Groundwater samples were collected from each of the AS/SVE wells, the SVE wells,
and the monitoring probes. Table 3-1 presents sample numbers and the sampling dates for
each well and monitoring probe. The analytical laboratory reports by ELAB, Inc. and
independent validation reports by EDS are retained in the Brown and Caldwell project files.
Electronic copies of the laboratory reports and validation reports are maintained in the
El Paso project files. The reports include the results for other VOCs not shown in
Table 3-1. The results for other VOCs are generally below their detection limits or at very
low concentrations. Groundwater samples were collected, analyzed, and validated using
methods consistent with the ongoing semiannual MNA sampling that is being performed

according to the RA Work Plan. The source area groundwater sampling was performed in
accordance with a QAPP that outlines the QA/QC samples required. Six QA/QC duplicate
samples were collected and are included with the summary results in Table 3-1. The
QA/QC duplicate sample results indicated adequate field precision. Based on the reports by
EDS, the relative percent difference (RPD) between the field duplicate pairs was less than
15 percent for all analytcs detected except one pair in which four of the analytes had higher
RPDs. EDS determined that the results with the higher RPDs indicated a slight variation in
analyte concentration. Other quality issues were addressed by EDS and are reflected in data
qualifiers in the Table 3-1.
The PCE concentrations in the source area groundwater wells/probes ranged from 17 µg/L
in MP-3 to 140,000 µg/L in EW-5. The TCE concentrations in the source area groundwater
ranged from not detected in several wells to 2,000 µg/L in MP-13. The cis-1,2-DCE
concentrations in the source area groundwater ranged from not detected in several wells to
4,000 µg/L in MP-13. The 25-well/probe locations had vinyl chloride results of not
detected with the exceptions of EW-1/SW-1, which had a result of 0.15 µg/L; EW-6, which
had a result of 2. 0 µg/L; and MP-8 which had a result of 1.9 µg/L. These data show that
reductive dechlorination has occurred, which requires reducing conditions.
Figure 3-8 presents bar charts with PCE, TCE, and cis-1,2-DCE results for the wells and
monitoring probes that were sampled, as part of the Performance Test, both prior to and
following air sparging. Of the 14 wells and monitoring probes charted in Figure 3-8, several
show marked reductions in contaminant concentratior:is following air sparging. On the bar
charts in Figure 3-8, the December and March data are from samples collected prior to air
sparging; the April and June data arc from samples collected after air sparging. Reductions
in cont.aminant concentrations following air sparging were in excess of an order of
magnitude in the two air sparging wells EW-1/SW-1 and EW-2/SW-2. Substantial
contaminate reductions following air sparging were also observed at EW-3 and EW-6.
Modest contaminant reductions were observed at EW-5 and MP-4. Contaminant reductions
may have occurred at other well locations but groundwater VOC data either were not
collected or were non-conclusive. The wells that were sampled prior to air sparging and in

both April and June 2001 following air sparging exhibited little to no measurable rebound in
voe concentration between the April and June sampling events.
Figures 3-9 through 3-11 show isoconcentration (isocon) maps for PeE, TeE, and cis-
1,2-DeE in the source area groundwater, respectively. The isocon maps are based on the
April 2001 (Event 3) sampling results that are presented in Table 3-1 along with April and
May 2001 sampling results from other monitoring wells at the Site within and adjacent to the
source area. The data from other monitoring wells at the Site are included in Appendix B.
In general, the PeE contours on Figure 3-9 show that there was probably more than one
area with elevated PeE concentrations. This is also evident for TeE and cis-1,2-DeE in
Figures 3-10 and 3-11. Prior to installation of the Phase I AS/SVE system of wells and
monitoring probes, only one monitoring well, W-17, was located in a high PeE
concentration area. The diversity of PCE concentrations in the source area groundwater
became apparent after the new wells and probes were installed and groundwater samples
were collected.
The mass of PeE in groundwater that is in and around the source area has been estimated
using the PCE isocon areas, average PCE concentrations, an assumed porosity, and the
projected groundwater thickness. Table 3-2 presents the estimated PeE mass as a range
from approximately 230 kg to 500 kg, based upon groundwater sampling data collected in
April and May 2001 following the air sparging test. The PCE is estimated to be primarily
within the shallow groundwater with only about three percent of the total estimated mass in
the intermediate groundwater. The reliability of these estimated masses is subject to
uncertainties from the site heterogeneity, the projected isocon areas, variability of the
analytical results, etc. If free product is present, the PCE mass would be higher than these
calculations predict. Also, the estimated masses do not include PCE from areas of the
plume where the PCE concentrations are less than 100 µg/L. Other VOes will contribute
some mass to the total voe plume but PeE is projected to constitute the majority of the
mass.
Figure 3-12 shows an isoconcentration map for the dissolved oxygen (DO) following the air
sparging portion of the Performance Test. DO concentrations of up to 8 ppm were

measured in the source area shallow groundwater and elevated concentrations were present
in the shallow groundwater outside the source area to the north and to the south. Most of
the monitoring wells away from the source area have only been sampled once for DO, and
as such, the elevated concentrations in these areas can not be definitely attributed to the air
sparging, only circumstantially.
3.5 VAPOR SAMPLING RESULTS
Table 3-3 presents the vapor sampling results for PCE and selected natural attenuation
daughter products including TCE, cis-1,2-DCE, and vinyl chloride. The analytical laboratory
reports by ELAB, Inc. are retained in the project files. The PCE concentrations in the vapor
from the extraction wells prior to SVE (Event 1 prior to SVE) ranged from 4 70 µg/L in
EW-10 to 7,700 µg/L in EW-8. The PCE concentrations in the monitoring probes from
Event 1 ranged from 380 µg/L in MP-7 to 16,000 µg/L in MP-13. TCE concentrations
ranged as high as 71 µg/L at MP-13; cis-1,2-DCE concentrations were as high as 46 µg/L at
MP-13. Vinyl chloride was not reported as detected for any of the wells.
Table 3-3 also presents data collected in July 2001 after completion of the Performance Test.
The July 2001 data shows VOC rebound effects following approximately one and one half
months of no SVE operations. The Draeger tube sample results show some PCE increase
in eight of the ten SVE wells after the period of no SVE operations.
The PCE concentrations reported for the two samples at the SVE blower inlet that
represent the combined vapor flow from all ten SVE wells were 3,300 and 3,500 µg/L, for
sampling Event 1. The TCE results at the blower inlet were 20 and 22 µg/L; the
cis-1,2-DCE results were 11 and 18 µg/L. Vinyl chloride was not detected at the inlet to the
blower.
Figure 3-13 presents a bar chart of the PCE concentrations in the extracted vapor before,
during, and after air sparging at each of the 10 SVE wells. The data shown in Figure 3-13
are from PCE-specific Draeger tube measurements. The PCE-specific Draeger tubes may

also indicate the presence of other chlorinated voes that are present in the vapor so the
tubes may over-report the PeE concentrations if other VOes are present. The data show a
consistent increase in PeE concentration during air sparging with a decrease after air
sparging. This is evidence that PeE is being moved from the shallow groundwater to the
vadose zone by the action of air sparging. Air sparging may also help mobilize additional
PeE present in the vadose zone as well as in the groundwater.
The PeE mass removed by SVE during the Performance Test period has been estimated
two ways as presented in Table 3-4. The PeE mass removed, based on laboratory analytical
data from vapor samples, is estimated to be 320 kg and the PeE mass removed, based on
the Draeger measurements, is estimated to be 440 kg. The PeE mass estimated by the
Draeger tube measurements may be biased either high or low, thus the mass estimate must
be qualified. Since the Draeger tubes also detect other chlorinated VOes in addition to PeE •
. that is present, the indicated PeE result may be biased high. In addition, for most of the
PeE concentrations at the beginning of SVE, the Draeger tube measurements were
recorded as greater than 300 ppm, the maximum range of the Draeger tubes used. When the
maximum range was exceeded, the concentrations were assumed to be 300 ppm, which
would bias the PeE result low. Table 3-4 indicates the productivity of the ten SVE wells at
mass removal. The mass removed by EW-6 and EW-7 is estimated to be zero since no
vapor flow was detected at these locations by the SeADA system instrumentation.
3.6 EVALUATION OF SOURCE AREA voe RESULTS
The voe data from the groundwater and vapor samples are consistent with the known
heterogeneity of the soils at the Site. In some cases, the locations of the higher PeE
concentrations in the groundwater correlate with the locations of the higher concentrations
in the vadose zone vapor. In other cases, there is not a clear correlation between the voe
data. At least two areas of higher PeE concentrations are indicated; one at or near
EW-1/SW-1 (W-17s) and a second at or near MP-13 and possibly MP-14. The area of
higher PeE concentrations north of MP-13 and MP-14 is not totally delineated due to the
greater spacing between the groundwater monitoring wells to the north and the lack of any
wells screened in the vadose zone.

The removal rate of PCE from the SVE wells has been calculated using the measured vapor
flow rates of the wells at an applied SVE vacuum of 60 in.W.C. (from Figure 3-1) and the
PCE-specific Draeger tube data (from Figure 3-13). Figure 3-14 shows the estimated PCE
removal rates by SVE from the extraction wells before, during, and after air sparging. As
expected, wells with no measured flow (EW-6 and EW-7) have no PCE removal (note that it
is believed that these wells do produce some flow but below the lower range of the pitot
tubes). The majority of the PCE mass is removed from EW-2, EW-3, EW-4, EW-5, and
EW-8. The combined PCE removal rates for all extraction wells is calculated to be 150 g/hr
before sparging, 330 g/hr during sparging, and 190 g/hr after sparging. The net increase
due to sparging is 180 g/hr, which corresponds to 4.3 kg/ day increased PCE removal due to
sparging. This removal rate would be expected to decline with time but it is still a significant
increase in PCE removal from the source area (beyond that by SVE alone).
The PCE-specific Draeger tube data and the measured vapor flow rate from the permeability
testing at the monitoring probes has been_ used to project initial PCE removal rates should
the monitoring probes be converted to SVE wells. Figure 3-15 presents the projected PCE
removal rates from the monitoring probes. The monitoring probes with removal rates
greater than 20 g/hr had PCE concentrations of greater than 300 ppm (upper limit of the
Draeger tube that was used) so the removal rates shown for these wells could actually be
higher. No data were collected for MP-12 so a PCE removal rate could not be calculated.

11 Data qualifiers are as follows:
a indicates that this compound was also detected in the methcxl blank and the data should be interpreted with caution.
D indicates that this sample was diluted because one of the compound concentrations exceeded the highest concentration range for
the standard curve.
J indicates that the reported result is estimated because the result is less than the estimated quantitation limit (EQL).
U indicates that the result was not detected above the method detection limit (MDL).

• Data qualifiers are as follows:
Table 3-3. Source Area Vapor Sampling Results for Volatile Organic Compounds
FCX-Statesville Superfund Site OU3
B indicates that this compound was also detected in the method blank and the data
should be interpreted with caution.
D indicates that this sample was diluted because one of the compound concentrations
exceeded the highest concentration range for the standard curve.
J indiCStes that the reported result is estimated because the result is less than the
estimated quantitation limit (EQL).
U indicates that the result was not detected above the method detection limit (MDL).
b "µg/LN data has been calculated from ppm data assuming Draeger tube reading is for PCE only.
c: "-" indicates that there was not an analysis or measurement performed.

4.0 CONCLUSIONS AND RECOMMENDATIONS
This section contains conclusions that have been derived from the Phase I Performance Test
data and recommendations for continued remediation of the OU3 soil and groundwater
contamination, including Phase II improvements to the AS/SVE system.
4.1 CONCLUSIONS
•
•
The air sparging and SVE equipment operated successfully during the Performance
Test:
One of the two redundant blowers was operated; the second blower was
available as backup but was not needed.
The SCADA system provided easy and reliable monitoring and control of the
AS/SVE process.
The air sparging compressor and pulsing controls performed as designed and
allowed air sparging flow rates up to 10 scfm per well at a delivery pressure of
approximately 15 psig.
The air-to-air heat exchanger cooled the vapor to within 5°F to 10°F greater
than the ambient temperature as measured after the first GAC vessel.
The GAC vessels operated as designed and one GAC change out was required
during the Performance Test.
The condensate drip traps and moisture separator effectively removed
condensate from the system that accumulated during the colder months. The
holding capacity of the drip traps was not sufficient to contain the quantity of
condensate collected between monthly system checks so the excess condensate
collected in the SVE header piping.
The selected locations of the SVE. and air sparging wells generally address the
source area contamination with the exception of areas to the north in the vicinities
of IYIP-13 and lYIP-14. Both of these locations have PCE concentrations in the
groundwater in excess of 10,000 µg/L. In addition, vapor concentrations of PCE

111 the vadose zone were in excess of 10,000 µg/L at MP-13. There may be
portions of the vadose zone within the source area that are not addressed due to
heterogeneity even though they are within the area of apparent influence of SVE.
Results of the helium tracer test indicate that the subsurface in the source area is
heterogeneous with respect to both air sparging and SVE. 1bis conclusion is
consistent with what was concluded from the 1998 AS/SVE pilot test. The helium
movement within the shallow groundwater did not correlate well ·with the helium
detected at the SVE well locations (vadose zone). At the air sparging flow rates
used ·for the Performance Test, the air was shown to move non-uniformly in
various _directions. To the north and west, a portion of the injected air appeared to
move beyond the estimated radius of influence of the SVE wells. The injected air
may also have moved in other directions within the groundwater. The
heterogeneity within the vadose zone was also evident from the wide range of
vapor flow rates that were achievable at the different source area well locations.·
The SVE system removes significant VOC mass from the vadose zone. The
estimated PCE mass removed during the 3.5 months of SVE operation was
between 320 kg and 440 kg, depending on the PCE concentration data used.
If the SVE system removes VOCs at the maximum estimated PCE removal rate
(440 kg per 3.5 months or 4.2 kg/day) for an entire year, the annual mass ternoved
would be as high as 1,500 kg/yr or 1.7 tons/yr. Using SVE only, the PCE
concentration is expected to decrease with time so the actual annual mass removed
would likely be less than 1.7 tons/yr.
The pneumatic permeability testing results indicated that most of the monitoring
probes could effectively be used as SVE wells if needed. The monitoring probes
that exhibited vapor flow rates in excess of 10 scfm were MP-5, MP-6, MP-11,
MP-13, and MP-15. The pneumatic permeability testing also indicated that two of
the SVE wells, EW-6 and EW-7, had no measured vapor flow.

The pressure and flow data from the air sparging wells indicated that there 1s
adequate pneumatic permeability at SW-1 and SW-2 to perform air sparging.
The air sparging system removed significant VOe mass from the groundwater
during the air-sparging portion of the Performance Test. This is evidenced by the
increase in PeE concentrations in the vapors from the SVE wells during air
sparging and the reduced voe concentrations in adjacent groundwater wells
following air sparging. The increase in PeE removal rate due to air sparging was
estimated to be 4.3 kg/ day (approximately equal to the SVE only removal rate)
based on an observed increase in PeE concentrations in the vapors from the SVE
wells. Therefore, the combined removal with AS/SVE would be as high as
approximately 8 kg/ day.
A vacuum decrease in the vadose zone during air sparging was observed at 19 of
the 25 monitoring wells and probes, indicating an·influence at those locations by
air sparging. Only the outermost monitoring probes (MP-1, MP-3, MP-7, MP-8,
and MP-14) and one extraction. well (EW-5) showed no influence (vacuum
decrease) during air sparging.
The rate of anaerobic biodegradation m and near the source area will likely
decrease as a result of air sparging. During the Performance Test, the DO
concentrations in the shallow groundwater were elevated in and near the source
area following the period of air sparging. The DO concentrations were also ,
measured in other Site wells after air sparging (see Figure 3-12); however, these
data are inconclusive since there are few pre-air sparging data to compare to. If air
sparging were performed to accomplish voe mass removal from the
groundwater, it would be appropriate to attempt to return the groundwater to
anaerobic conditions once air sparging is discontinued. However, the feasibility of
returning the shallow groundwater zone to anaerobic conditions may be limited by
the subsurface heterogeneity.

4.2 RECOMENDATIONS
Based on the results of the Performance Test, there are three primary recommendations for
moving forward with the OU3 remediation. These primary recommendations are as follows.
•
•
•
Continue operations of the SVE system with some revisions to operations .
Proceed with carefully controlled air sparging operations .
Proceed with Phase II design and construction to enhance the AS/SVE system .
Each of these recommendations is further discussed below.
4.2.1 Continue Operations of SVE System
The SVE system should continue to be operated with the following suggested revisions to
improve effectiveness and reduce waste generation:
•
•
•
Operate the SVE system to include scheduled "off" times to improve efficiency:
Average VOC concentration will be higher due to VOC rebound during off
periods.
GAC loading efficiency improves when average VOC concentrations are
higher.
Electrical usage is less per unit mass of VOC removed.
It is recommended that during the warmer months, SVE operations be limited to
night hours when ambient temperature is cooler, thus improving the GAC loading
efficiency and reducing the impact upon daytime activities by plant personnel.
This can be done manually using the SCADA control system until automated
features are added during the Phase II construction.
Ids recommended that the SVE system be turned off during cooler periods when
the ambient temperature in the equipment area is less than the extracted vapor
temperature. This will reduce or eliminate the accumulation of condensate waste.

This can be done manually using the SeADA control system until the control logic
software can be reconfigured during the Phase II construction.
It is recommended that the drip traps be modified to allow collection of larger
volumes of condensate before draining is needed.
Once the voe mass removal rate diminishes, periodically cycle the SVE wells. As
an example, perform SVE with half of the wells for a time period and then switch
to the other half. This well cycling should improve voe recovery by changing
vapor flow patterns within the vadose zone, thereby moving voes from dead-
flow zones to the SVE wells.
4.2.2 Proceed with Air Sparging Operations
It is recommended that the air sparging system be operated since the system effectively
removed voe mass from the groundwater during the Performance Test. The following
recommendations are made related to the application of air sparging:
•
•
•
•
The air sparging should be performed by pulsing to improve the VOC removal
effectiveness. A pulsing cycle of approximately every one to two hours is
recommended initially. Adjustments may be needed once the cycling effectiveness
is measured.
The sparged air flow should be maintained at a low rate (no more than 2 scfm) to
potentially improve capture of the injected air by the SVE system.
If the SVE system is operated periodically, then the rur sparging should be
discontinued prior to shutdown of the SVE system to facilitate capture of the
vapors by the SVE system.
Semiannual groundwater sampling of selected source area wells is recommended in
order to monitor the progress of the groundwater remediation.

• When air sparging is eventually shut down, it is recommended that appropriate
compounds be injected into the source area to help the groundwater return to
anaerobic conditions to the extent practicable.
4.2.3 Proceed with Phase II Design
A Phase II design and construction is recommended to improve the effectiveness and
coverage of the AS/SVE system for removal of VOCs from the source area. It is
recommended that the design consider the following improvements:
•
•
•
•
•
Convert selected monitoring probes to SVE wells to increase VOC removal
effectiveness. Candidate monitoring probes are MP-5, MP-6, MP-7, MP-9, MP-10,
MP-13, and MP-15.
Convert selected monitoring probes to air sparging wells. Candidates are MP-13
and MP-14 on the northern side of the plant where groundwater PCE
concentrations are high relative to other locations.
Install additional SVE wells and monitoring probes to the north of the plant to
. capture vapors and sparge air. The numbers and locations of new wells and
monitoring probes would be evaluated and selected during the Phase II design.
Update the SCADA system software and controls to accommodate the Phase II
improvements and to allow for automatic timed on and off periods for the
AS/SVE system operations.
Modify the drip traps to increase the condensate holding capacity .
The recommended design improvements would be possible without the need to modify or
increase the capacity of the blower system, compressor system, GAC vessels, or header
p1pmg. These recommended design features would be implemented as follows:

Prepare a Phase II design report, plans, and technical specifications for the
improvements as an addendum to the Phase I design documents. Obtain USEPA
and North Carolina Department of Environment and Natural Resources
(NCDENR) review and approval
Procure subcontractors, install wells, and install Phase II improvements to
AS/SVE system. Consider using the same subcontractors that performed the
Phase I construction for efficiency and continuity.
Prepare and issue a Phase II construction completion report
Update the AS/SVE O&M Manual to include the Phase II improvements .

Table A-1. Data from Monitoring Wells Used for Evaluation of Monitored Natural Attenuation•
FCX-Statesville Superfund Site OU3
TABLE FOOT NOTES:
a Data qualifiers are as follows:.
·-· indicates that there was not an analysis or measurement performed.
B indicates the analyte was detected in a blank sample.
D indicates that the result is from a diluted sample.
E indicates that the result exceeded the upper limit of the linear range of the calibration curve.
J indicates the result is estimated.
N indicates the result is estimated.
NR indicates the result is not reportable because it was determined as unusable by the data validator.
U indicates thal the result was less than one-fifth of the contract-required quantitation limit {CRQL); the reporting limit precedes the ·u· qualifier.
bMonitoring weU W-5s was sampled but not purged; the sample was taken on June 8, 1999, and the NAPS were collected on June 9, 1999.
cvoc data forW-20d from September 1998 are DQL Ill.
dMonitoring wen W-31s was resampled on 6/10/99 using a slower purge rate.
'Additional aluminum data can be found in Table 3-4 of the Pre-Design Investigation Report
1 This result appears to be suspect relative to what is expected. Value should be considered estimated.
General Notes:
Bevated DOs may be due to·pumping the weU dry and then collecting water that has been aerated.
Monitoring weD W-12s was dry during December 1998, June 1999, June 2000, November 2000, and April 2001 sampling events.
Monitoring well W-22s was dry during the June 1999 sampling; W-17s did not have enough water to purge or sample during the June 1999 sampling.
voe data from December 1999 sampling has been rounded to two (2) significant figures.
Monitoring wells W-225 and W-2'h were not sampled during the November 2000 and Apn1 2001 sampling events due to inaccessibility.
