MONITORING REPORT
NOVEMBER 3, 2005 SAMPLING EVENT
. · NEW HANOVER COUNTY AIRPORT BURN PIT SUPERFUND SITE
WILMINGTON, NORTH CAROLINA.
DECEMBER 13, 2005 ·
CATLIN PROJECT NO.194-040
1.0 .PURPOSE
2.0
The purpose of this report is to present the latest data (May 2005 through November 2005)
regarding the latest surficial groundwater quality and remediation efforts at the New Hanover
County Airport Bum Pit Stiperfund Site on Gardner Drive, Wilmington, North Carolina (see
Figure 1) since the last (May 2, 2005) groundwater sampling event. 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 GWQS) .. Since 1998 the compound of concern has been benzene dissolved. in the site
surficial groundwater.
SITE GROUNDWATER MONITORING WELLS
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 III monitoring
wells TMW-1 and TMW-2 are screened at depths of 40-45 and 38.5-43.5 feet BLS
respectively. Monitoring well construction data is provided in Table I. Figure 2 illustrates the
current groundwater monitoring well locations in relation to the site map. ·
Monitoring wells within the historic dissolved benzene plume boundary have been designated
performance verification wells. These wells are located in interstitial 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 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. 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-013andCMW-
016.

• Check and adjust system to ensure proper operation .
• Measure dissolved oxygen (DO) in MWD-002.
Semi-Annually (May and November)
In addition to the monthly activities, CATLIN personnel also conduct the following activities
on a semi-annual basis: •
• Gauge and sample performance verification and compliance monitoring wells per
EPA Method 602.
• Measure DO in MWD-002 .
• Prepare a monitoring report for submission to USEPA, NCDENR and PRPs. The
report includes:
system status
updated groundwater table contour map
updated groundwater contaminant isoconcentration map
tabulated field and laboratory analysis summary table
independent laboratory reports
SITE ACTIVE REMEDIATION ACTIVITIES
In 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. 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". The 79 air_ injection
wells are divided into 16 separate zones. Each zone is activated for
· approximately 75 minutes every day. 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.
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 May
2, 2005 sampling event, the PAS system has operated approximately 80 % 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.
Note -Since the active site remediation efforts were initiated, remnant
groundwater contamination has apparently been reduced to the area around
site monitoring wells MWD-002 and PVMW-014. Therefore, on October 3,
2005 air sparge 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 twice a day (see Figure 6). If
contaminant concentrations rebound in the inactive zones the air sparge
·efforts can be reactivated quickly.

5.0 SUMMARY OF SURFICIAL GROUNDWATER TABLE DAT A
6.0
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 3, 2005. While gauging the site monitoring wells, air sparge
efforts had just ceased at zone 12 and were initiating in zone 14. The depth to groundwater
table data has been subtracted from the TOC elevation to determine the site groundwater
table elevations .as of November 3, 2005. The November 3, 2005 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 su_rficial
groundwater table contours illustrated Figure 4.
A review of Figure 4 indicates a groundwater high around performance verification well
PVMW-014 as a result of the PAS efforts at nearby zones. The apparent overall site-wide
groundwater flow direction is toward_ the southwest 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 ih Table 2. ·.
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,
2005, CATLIN has performed six 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 FIEW 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 l 2~volt pump (Geopump
or whale) to pump recovered groundwater through a flow through cell. Groundwater
DO measurement are measured with a YSI Model 650 multi-parameter water quality
instrument and Model 600XL sonde placed in the flow through cell. Groundwater DO
levels, 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, its
position in an interstitial zone between sparge points and the depth of its screened
interval. Since the last (May 2, 2005) sample event DO measurements at MWD-002
have ranged from 0.1 I to0.72 mg/L. On November 3, 2005 DO measurements at the
performance verification wells ranged from 0.08 to 2.29 ug/L. Performance
verification wells with greater than 0.5 mg/L DO demonstrate the positive influence

of the PAS efforts. DO measurements at the compliance monitoring wells .ranged
from 0.11 to 0.38 ug/L, typical of uninfluenced groundwater.
GROUNDWATER SAMPUNG
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 an 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 paranieters.
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 Laborntories; 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
Since July of 1998 the compound of concern has been dissolved benzene
concentrations within the site surficial groundwater. EPA Method 602 analysis of the
latest site groundwater samples found only the groundwater ·sample from
performance verification well PVMW-014 exhibited benzene concentrations (3.20
ug/L) above applicable 2L GWQS of I ug/L. For the first time a groundwater sample
from performance verification well MWD-02 has tested compliant for all EPA .
· Method 602 analytes.

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 80% of the
period from the May 2005 sampling event to the present.
Surjicial Groundwater Quality
• · The latest groundwater analyses revealed the site·surficial groundwater, in the
vicinity of performance verification well PVMW-014, contains . minor
concentrations (3.20 ug/L) 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 benzene concentration has declined from 18.6 ug/L to <l ug/L and
benzene concentrations at PVMW-014 have decreased to 3:20 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 PVMW-014 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 froni 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}.
LIMITATIONS
