I 1.0 PURPOSE
I
I
I
The purpose of this report is to present the latest data (May 2006 through
November 2006) regarding the surficial groundwater quality and remediation efforts
at the New Hanover County Airport Burn Pit Superfund Site on Gardner Drive,
Wilmington, North Carolina (see Figure 1 ). Historic usage of the site has impacted
the site surficial groundwater with dissolved Volatile Organic Compounds (VOC) in
excess of current NCAC T15A:02L North Carolina Groundwater Quality Standards
(2L GWOS). The compound of concern has been dissolved benzene within the site
surficial groundwater.

Currently, there are twenty-six site groundwater monitoring wells or piezometers.
Twenty-four are Type I and II monitoring wells or piezometers screened at depths
ranging from approximately one to twenty-eight feet below land surface (BLS). Two
Type Ill monitoring wells TMW-1 and TMW-2 are screened at depths of 40-45 and
38.5-43.5 feet BLS, respectively. A summary of site monitoring well construction data
is provided in Table 1 . Figure 2 illustrates the current groundwater monitoring well
locations in relation to the site map.
Site groundwater monitoring wells within the historic dissolved benzene plume
boundary have been designated performance verification wells. These wells are
located in irlterstitial zones between sparge points and are intended to provide data
points to monitor contaminant reduction and dissolved oxygen levels within the deeper
portion of the surficial aquifer. One performance verification monitoring well
(PVSMW-002, located in the burn pit source area) is screened from one to ten feet
BLS and is used to verify contaminant reduction within the shallow portion of the
surficial aquifer. Performance verification wells include: MWD-001, PVSMW-002,
MWD-002, MWS-003, PVMW-010, PVMW-011, PVMW-014 and PVMW-015.
Wells outside the historic dissolved benzene plume boundary have been designated
compliance monitoring wells and are used to evaluate potential migration of dissolved
compound(s) of concern. Compliance monitoring wells currently employed to monitor

tabulated field and laboratory analysis summary table
independent laboratory reports
4.0 SITE ACTIVE REMEDIATION ACTIVITIES
In accordance with the site Final Design Remedial Report, the performance goal for
remediating non-compliant voe concentrations within the impacted site surficial
aquifer is 1 ug/L of benzene, or as agreed to by involved over sight personnel. To
achieve this objective a pulse air sparge system consisting of air compressors, 79
air injection wells, and associated controls has been designed and installed at the
site. Pulse Air Sparge (PAS) injection wells were installed to depths of 23 to 25 feet
below land surface. The locations of the current PAS injection wells are shown on
Figure 3.

4.1 PULSE AIR SPARGE (PAS)
4.1.1 Pulse Air Sparge Description
Pulse Air Sparge consists of injecting a pulse of ambient air within or
below the contaminated zone of the impacted aquifer, through an air
sparge well. As air is injected into the aquifer, a de-watered sphere
grows around the sparge point. This spherical volume of air
continues to grow displacing groundwater until just before the top of
the sphere "breaks through" the surface of the ground water table.
Prior to "breakthrough", the air injection is terminated, injected air
migrates back up to the ground surface, and the aquifer is allowed to
recharge before the next "pulse". Injecting air into the impacted
aquifer reduces dissolved gasoline compounds through volatilization
and biodegradation by indigenous aerobic microbes. Studies have
repeatedly shown aerobic microbes, as opposed to anaerobic
microbes, biodegrade dissolved gasoline compounds more rapidly.
The current system consists of 79 air injection wells divided into 16
separate zones. Zones are sequentially activated across from the site
from each other to prevent interference and mitigate potential
contamination migration from the temporary high water table
conditions. However, since the active site remediation efforts were
initiated, remnant groundwater contamination has been reduced to
the area around site monitoring wells MWD-002 and, on occasion,
PVMW-014. Therefore, on October 3, 2005 air sparge zones
hydraulically up gradient of MWD-002 and PVMW-014 (zones 2, 4, 5,
10, 11, 15 and 16) have been turned off. Zones in and around site
monitoring wells MWD-002 and PVMW-014 (Zones 1, 3, 6, 7, 8, 9,
12, 13 and 14) are now active for approximately 75 minutes twice a
day (see Figure 6). If contaminant concentrations rebound in the
inactive zones the air sparge efforts can be reactivated quickly.
4.1.2 Performance
Since the May 8, 2005 sampling event, the PAS system has operated
approximately 78% of the time due to periodic power outages having
disrupted system operation. Ultimately, site remediation performance
is evaluated by reviewing the groundwater dissolved gasoline
compound concentrations trend over time.
5.0 SUMMARY OF SURFICIAL GROUNDWATER TABLE DATA
Each of the site monitoring well top of casing (TOC) elevations has been surveyed
in relation to mean sea level (MSL). The latest groundwater table depths were
obtained at all site monitoring wells on November 10, 2006. The depth to
groundwater table data has been subtracted from the TOC elevation to determine

the site groundwater table elevations as of November 10, 2006. The November 10,
2006 groundwater table depth and elevation data has been summarized on Table 1.
The elevation data was entered into contouring software program (AutoCAD Land
Development) to generate the surficial groundwater table contours illustrated in
Figure 4.
During the November 10, 2006 site visit the PAS system was off. A review of Figure
4 indicates a relatively flat site surficial water table reflecting the lack of influence
from the PAS system. The apparent surficial groundwater flow direction within the
site area of interest (MWD-002 and PVMW-014) is toward the south. Historically,
the predominant site-wide groundwater flow directions have been to the southwest
with a northeasterly component of flow normally observed beneath the northeastern
portion of the property. Historical site groundwater table elevation data has been
listed in Table 2.
6.0 SUMMARY OF GROUNDWATER QUALITY TESTING
Prior to system installation, CATLIN personnel conducted a site groundwater
sampling event to provide a pre-construction baseline of the dissolved contaminant
plume. As of November 3, 2003, CATLIN has performed eight post system
installation sampling events. During each sampling event, CATLIN personnel
recorded selected groundwater field parameter data and obtained groundwater
samples in general accordance with the following procedures.
6.1 FIELD MEASUREMENT (DISSOLVED OXYGEN)
Initial uninfluenced site groundwater DO levels were typically less than 0.5
milligram per Liter (mg/L). Aerobic groundwater conditions are generally
those with DO levels greater than .1.0 ug/L. Site DO measurements are
obtained by utilizing a low flow 12-volt pump (Geopump or whale) to pump
recovered groundwater through a flow through cell. Groundwater DO
concentration measurements are measured with a YSI Model 650 multi-
parameter water quality instrument and Model 600XL sonde placed within the
flow through cell. Groundwater DO concentrations, within the PAS injection
well radius of influence, will fluctuate in accordance with the PAS air injection
cycle.
MWD-002 is gauged monthly due to its central location in relation to the site,
position in an interstitial zone between sparge points, and the depth of
screened interval. Since the last sample event (May 8, 2006), DO
measurements at MWD-002 have ranged from 0.21 to 2.47 mg/L.
During the November 10, 2006 sample event, DO measurements were also
obtained from selected performance verification wells. DO measurements at
performance verification wells PVSM-002, PVSM-010, PVSM-011, PVSM-014
and PVSM-015 ranged from 0.12 to 1.46 ug/L. Performance verification

wells with greater than 0.5 mg/L DO demonstrate a positive influence from
the PAS efforts.
6.2 GROUNDWATER SAMPLING
Prior to sampling, each well was purged to ensure the collected sample is
representative of the surficial aquifer. Purging was performed by removing a
minimum of three well volumes from each monitoring well using disposable
bailers. A new set of disposable nit rile gloves and bailer were utilized for each
sample collected.
For groundwater monitoring wells where groundwater is also tested for
selected geochemical parameters, a pump was used to extract groundwater
from each well. The extracted groundwater was delivered to a flow-through
cell via clean polyethylene tubing. Temperature, conductivity, and pH
conditions were measured using an YSI Model 650 multi-parameter water
quality instrument with Model 600XL sonde. Measurements were recorded at
one-minute intervals until the readings reached equilibrium. Once stabilized,
the well was sampled and the recorded data was used to document the
selected field parameters. The Model 600XL sonde, as well as the test cell
were cleaned after each sample was collected in accordance with the
manufacturer's instructions.
Groundwater samples were placed in laboratory provided glassware labeled
with the well ID, sample date, site name, sampler, and placed in an iced
cooler. Samples were delivered to SGS Environmental, Inc. (North Carolina
Certification #481) in Wilmington, North Carolina for analysis. To determine
remnant-dissolved gasoline compound concentrations (in ug/L), all
groundwater samples are analyzed for volatile compounds per EPA Method
602 plus total xylenes.
6.3 GROUNDWATER QUALITY -EPA METHOD 602
Since July 23, 1998 the compound of concern has been dissolved benzene
concentration within the site surficial groundwater. EPA Method 602 analysis
detected benzene concentrations, in excess of 2L GWQS (1 ug/L), only in
the groundwater sample from monitoring well MWD-002 (17.9 ug/L).

on Table 4. A copy of the SGS laboratory report for the latest sample event
has been provided in Appendix A. To illustrate the historical groundwater
remediation trend, a graphical representation of historical benzene
concentrations at site monitoring wells MWD-001, MWD-002, MWS-003,
MWD-006, PVMW-011, PVMW-014 and PVMW-015 has been prepared (see
Appendix B).
7.0 CONCLUSION AND RECOMMENDATIONS.
7.1 CONCLUSIONS
Based on the field and laboratory data obtained during the most recent
monitoring period, the following conclusions are provided:
Active Remediation System Operation
The PAS system has been operating properly for approximately 78% of
the period since the last groundwater sampling event (May 2006).
Surficial Groundwater Quality
The latest groundwater analyses detected benzene concentrations in
excess of 2L GWQS (1 ug/L), only in the groundwater sample from
monitoring well MWD-002 (17.9 ug/L).
In reviewing the historical dissolved contaminant concentration data (Table 4
and graph in Appendix B), the overall trend indicates a progressive decline in
benzene concentrations within the site groundwater.

Benzene concentrations do not appear to be migrating upwards in the water
column as evidenced from the sample results collected from monitoring wells
MWD-002 and PVSMW-002. PVSMW-002 (screened to 10 feet below land
surface (BLS), which is in close proximity to MWD-002 (screened to 27 feet
BLS), continued to display benzene concentrations below 2L GWQS.
7.2 RECOMMENDATIONS
CATLIN recommendations are based on a review of the current site
conditions and are as follows:
• Continue with the monitoring and maintenance schedule outlined in the
Final Remedial Design Report.
• Continue to focus remediation efforts of the pulsed air sparge system to
zones southwest of PVMW-011, specifically zones 1, 3, 6, 7, 8, 9, 12, 13,
and 14 (see Figure 6).
8.0 LIMITATIONS
The field and groundwater data evaluated as part of this monitoring report provide
isolated data points and may not represent conditions at every location in the project
area. Analyses and conclusions of this report, being based on interpolation
between data points at the project area, may not be completely representative of all
site conditions. Conclusions and recommendations of this monitoring program and
report are based on the best available data in an effort to comply with current
regulatory requirements.
