MONITORING REPORT
MAY 2005 SAMPLING EVENT
NEW HANOVER COUNTY AIRPORT BURN PIT SUPERFUND SITE
WILMINGTON, NORTH CAROLINA
MAY 25,2005
CATLIN PROJECT NO. 194-040
PURPOSE
The purpose of this report is to present data regarding surficial groundwater quality and
remediation efforts (July 2004 through May 2005) at the New Hanover County Airport Bum
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 Tl 5A:02L North Carolina Groundwater
Quality Standards (2L GWQS). This report focuses on site groundwater remediation and
monitoring efforts completed since the July 2004 sampling event.
SITE GROUNDWATER MONITORING WELLS
Currently, there are sixteen monitoring wells selected to monitor groundwater characteristics on
site (see Figure 2). They are positioned to encompass the compliance boundary to ensure
effective monitoring of the contaminant' plume. The monitoring wells are screened at depths
ranging from approximately one to twenty-eight feet below land surface (BLS). Monitoring
well construction data is provided in Table 1. Monitoring wells within the historic dissolved
benzene plume boundary have been designated performance verification wells and are intended
to provide data points to monitor the reduction of groundwater contaminants. 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 dissolved plume migration. Compliance monitoring wells currently employed to
monitor the groundwater plume boundary include: MWS-004, MWD-006, CMW-007,
CMW-008, CMW-009, CMW-012, CMW-013 and CMW-016.
Performance verification monitoring wells are located in interstitial zones between sparge
points and are used to obtain data regarding contaminant reduction and dissolved oxygen levels,
generally within the deeper portion of the surficial aquifer. One performance verification
monitoring well (PVSMW-002, located in the bum 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.

SITE ACTIVE REMEDIATION ACTIVITIES
ln accordance with the site Final Design Remedial Report, the performance goal for
remediating non-compliant VOC concentrations within the impacted site surficial aquifer is 1
ug/L of benzene or as agreed to by involved entities. A pulse air sparge system consisting of
79 injection wells has been designed and installed at the site to remediate the dissolved VOC
groundwater plume. The locations of the current pulse air sparge (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 and the aquifer is allowed to recharge before the next "pulse".
The intent of this activity is to volatilize dissolved gasoline compounds
within the impacted aquifer, and supply oxygen to indigenous aerobic
microbes. Indigenous aerobic microbe species important in dissolved
gasoline compound degradation utilize dissolved oxygen (DO) from the
aquifer as an electron acceptor to convert dissolved gasoline compounds to
CO2, water, and biomass. Aeration efforts of the PAS system replenish
dissolved oxygen into the aquifer. Studies have repeatedly shown aerobic
microbes, as opposed to anaerobic microbes, biodegrade dissolved gasoline
compounds more rapidly.
4.1.2 Performance
The PAS system performance was optimized during system calibration.
Calibration of the PAS system occurred for approximately two weeks
following system start-up. The calibration period consisted of adjusting
airflow to specific zones in order to optimize performance and abandoning
and re-drilling air sparge wells that were short-circuiting. In addition, during
site visits, CATLIN personnel monitor compressor run times. Since the July
2004 sampling event, the PAS system has operated approximately 70 % of
the time. Periodic power outages have 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 May 2, 2005. The depth to groundwater table data has been subtracted
from the TOC elevation to determine the site groundwater table elevations as of May 2,
2005. This latest groundwater table data has been summarized on Table 1. To evaluate
surficial groundwater flow direction and gradient, the groundwater elevation data was
entered into a contouring software program (AutoCAD Land Development). Current data
indicates a relatively flat groundwater table beneath the site with noticeable influence from
the pulsed air sparging system. Overall, groundwater flow direction is toward the southwest.

6.0
Groundwater apparent gradient calculated between MWD-002 and MWD-006 is 0.0024
(southwest). Historically, groundwater flow directions have been generally similar to current
observations; however, a northeasterly component of flow normally observed beneath the
northeastern portion of the property was not observed during this event. The latest (May 2,
2005) surficial groundwater table contour data has been illustrated on Figure 4.
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 May 2, 2005,
CA TUN has performed five post system installation sampling events. During each sampling
event, CA TUN personnel recorded selected groundwater field parameter data and obtained
groundwater samples in general accordance with the following procedures.
6.1
6.2
FJEW MEASUREMENT (DISSOLVED OXYGEN)
A groundwater DO measurement was taken from within MWD-002 at a depth of
approximately twenty-one feet BLS on May 2, 2005. The DO measurement was
obtained using a YSI Model 650 multi-parameter water quality instrument and Model
600XL sonde. MWD-002 was chosen to gauge performance of the pulse air sparge
system due to its central location in relation to the site, its position in an interstitial
zone between sparge points and the depth of its screened interval. A DO
measurement of 4.60 mg/L was recorded for MWD-002. The May 2005 DO
measurement of 4.60 mg/L represents an increase from the 3.25 mg/L DO level
recorded during the July 2004 sampling event. DO levels for MWD-002 will
continue to be monitored at the site as proposed.
GROUNDWATER SAMPLING
Prior to sampling, each well was purged to ensure the collected sample was
representative of the surficial aquifer. Purging was performed by first removing a
minimum of three well volumes from each monitoring well using disposable hailers. A
pump was then used to extract groundwater from each well. The extracted groundwater
was delivered to a flow-through cell via clean polyethylene tubing and temperature,
conductivity, and pH were measured using a YSI Model 650 multi-parameter water ' quality instrument with Model 600XL sonde. Measurements were recorded at one
minute intervals until the readings had equilibrated. Once stabilized, the well was
sampled and the recorded data was used to document the selected field parameters.

Groundwater samples were obtained from new polyethylene tubing attached to the
discharge end of the test cell. The Model 600XL sonde, as well as the test cell were
cleaned after each sample was collected in accordance with the manufacturer's
instructions. A new set of disposable gloves and bailer were utilized for each sample
collected.
Each sample was placed in laboratory prepared sample glassware labeled with the well
ID, sample date, site name, sampler, and placed in an iced cooler. Samples were
delivered to Paradigm Analytical Laboratories, Inc. (Paradigm; North Carolina
Certification #481) in Wilmington, North Carolina for analysis. To determine
groundwater concentrations (in ug/L) of remnant-dissolved gasoline compounds, all
groundwater samples were analyzed for volatile compounds per EPA Method 602.
GROUNDWATER QUAUTY -EPA METHOD 602
The only EPA Method 602 analyte detected above 2L GWQS was benzene at a
concentration of23.6 ug/L in the groundwater sample collected from monitoring well
MWD-002.
Benzene concentrations as evaluated from latest sample event (May 2, 2005) data,
can be summarized as follows:

7.0 CONCLUSION AND RECOMMENDATIONS
7.1
7.2
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 70% of the
period from the July 2004 sampling event to the present.
Surficial Groundwater Quality
The latest groundwater analyses revealed the site surficial groundwater contains
minor concentrations of benzene in excess of applicable 2L GWQS.
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 at all· monitoring well locations. Compared to the baseline data,
MWD-002 exhibited a rise to 23.6 ug/L from 18.6 ug/L and PVMW-014 decreased to
<1 ug/L from 4.4 ug/L. In contrast to the July 2004 sampling event, MWD-002
decreased to 23.6 ug/L from 69 ug/L. Currently, only MWD-002 contains a non-
compliant concentration of benzene.
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.
RECOMMENDATIONS
CA TUN 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.
• Focus remediation efforts of the pulsed air sparge system to zones southwest of
PVMW-011, specifically zones 1, 2, 3, 6, 7, 8, 9, 12, 13, and 14 (see Figure 6).
• Continue semi-annual monitoring activities as outlined in Section 3.0 Site
Monitoring Plan.
