Summary of Assessment Results
As presented in the December 1999 CSA report prepared by Arcadis, chlorinated solvent
impacted soil was identified beneath the former Koretizing dry cleaning building in the
vicinity of the former dry cleaning machine. Arcadis supervised the excavation of the
impacted soil in April 1999. Post excavation sidewall sample analytical results indicated the
removal of impacted soil was complete horizontally. Analytical results of samples collected
from the base of the excavation indicated relatively low levels of targeted compounds. Due
to the shallow nature of groundwater at the site (3-4' bls), the samples collected from the
base of the excavation would represent impact below the groundwater surface.
Arcadis installed nine monitoring wells at the site. Based upon field measurements and
analytical results, Arcadis determined: groundwater flow direction was to the
south/southwest; groundwater was impacted by several chlorinated compounds at
concentrations above 2L standards; the impact to groundwater was horizontally and
vertically delineated.
In February 2007, W&R installed a monitoring well outside the former dry cleaning
building immediately adjacent and downgradient from the former dry cleaning unit to
determine if impacted groundwater is present from under the building. In addition, W&R
sampled the new well and existing nine monitoring wells previously installed at the site.
Based upon the analytical results, the impact to groundwater had no longer been delineated
horizontally. W&R returned to the site in July 2007 to install 14 additional monitoring wells
to horizontally delineate the impact to groundwater at the site. Analytical results indicated
another source area of chlorinated solvents impact to groundwater in the downgradient
direction in the vicinity of the Café Arone restaurant,which is currently vacant.
W&R conducted a historical directory search for the Café Arone property, and did not
identify any information indicating land use consistent with use of chlorinated solvents at
this location.
In January 2008, W&R conducted a soil gas survey in the vicinity of the Café Arone
restaurant using Gore Module technology. The results of this survey were inconclusive.
W&R returned to the site in March/April 2008 to conduct the next phase of assessment
using a Geoprobe and mobile lab. Initially, soil samples (WR-A through WR-R) were
collected adjacent to 5 storm sewer drop inlets related to a stormsewer line that originated to
the west of the former dry cleaner site and flowed south under the Café Arone restaurant and
beyond. These samples were immediately submitted to the mobile lab for analysis and no
targeted compounds were identified. These five borings were advanced into the
groundwater, and temporary wells were installed and sampled. Although targeted
compounds were detected,the concentrations identified did not suggest that the storm sewer
was a source of impact or a preferential migration pathway. Ten additional temporary wells
were installed to delineate the area of groundwater impact at the site. Based upon the mobile
laboratory analytical results of samples collected from those temp wells, five permanent
Type II monitoring wells (MW-24 through MW-28) were installed for plume delineation.

All existing permanent wells were sampled for laboratory analysis. Based upon the
analytical results, the impact to groundwater has been delineated except to the southeast
(across Ward Blvd.) of the second area of impact identified near the Café Arone restaurant.
W&R also collected samples from two existing monitoring wells (EW-1 and EW-2) located
at a former gas station downgradient from the Café Arone restaurant. Only petroleum type
compounds were identified in the samples collected from these wells. Due to elevated
petroleum compound concentrations, the detection limits were elevated and therefore low
concentrations of chlorinated solvents if present would not have been detected.
Based upon the depth to water measurements groundwater flow direction at the site is
generally to the south trending to the southeast downgradient of the Café Arone restaurant.
The approximate hydraulic gradient is 0.006 ftlft.

vicinity of the site utilizes municipal water. According to Wilson's City Engineer,no drinking wells are
permitted inside the city limits,but irrigation wells are permitted in the area. The storm sewer system on
the site discharges to a stream diverted beneath the southern adjacent property. A church with a daycare is
located approximately 430 feet on the western adjacent property. The Vinson-Bynum School and the
county hospital are located approximately 1250 and 1810 feet west of the former facility,respectively.

Site-Specific Fate and Transport Parameters
Soil samples were collected from the vadose zone up gradient of the former dry cleaning
facility for geotechnical analyses of dry bulk density, porosity, and volumetric water
content. The sample was collected boring B-1 from 0 to 4 feet bls as representative of the
lithology present at the site and submitted to Geotechnics (Raleigh, NC) for the
geotechnical analyses. Analytical results of the unsaturated sample indicate a dry bulk
density of 78.6 pcf, a porosity of 0.53, a volumetric water content of 0.15, and an average
specific gravity of 2.69. A saturated sample was collected during the installation of
monitoring well MW-9 for analysis of fractionated organic carbon (FOC). The sampled
was collected below the water table from 8 to 10 feet bls. Analytical results of the
saturated sample indicate a FOC content of 0.00070 grams of Carbon/gram of soil.
Geotechnical laboratory reports are included in Attachment 21.
Hydraulic conductivity has not been determined for the site. W&R recommends
conducting slug tests at the site to determine the hydraulic conductivity

for precision.
J4 The associated batch QC was outside the established quality control range
for accuracy.
Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
unless qualified as 'R' (Rejected) .
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

RE: Koretizing Cleaners, Wilson, NC - Final Data Report
KB Labs Project # 08-48
Dear Mr. Kwiatkowski:
Enclosed is the final report of the on-site analysis performed by KB Labs, Inc. at the above
referenced site. Samples were collected and analyzed from March 31 to April 1, 2008. Included
are a brief project narrative, data report narrative, tables listing quality control results, final
analytical results, and sample chain-of-custody form. This information will also be sent
electronically.
KB Labs' mobile laboratory (KB-2) has been inspected by the North Carolina Department of
Environment and Natural Resources and is certified by the Division of Water Quality. Our
personnel, methodology. proficiency testing, and quality assurance requirements comply with
the guidelines of 15 NCAC 26.0500, 2H.0900 and 2L .0100, .0200, .0300, and 2N .0100
through .0800 and with the consensus standards adopted at the National Environmental
Laboratory Accreditation Conference (NELAC). Data for the site referenced above were
determined in accordance with published procedures under Test Methods for Evaluating Solid
Waste (EPA SW-846, Update III Revised May 1997). Unless otherwise indicated on the quality
control narrative accompanying the data report, the quality assurance and quality control
procedures performed in conjunction with analysis of groundwater samples demonstrated that
the reported data met our requirements for accuracy and precision under NCDENR and NELAC
Standards.
If you have any questions, please do not hesitate to call me or Kelly Bergdoll, President of KB
Labs, at [phone].
Sincerely,
KB Labs, Inc.

PROJECT NARRATIVE
Project Scope
From March 31 to April 1 , 2008, a total of 44 samples (5 soils and 39 Water) were
analyzed for Withers & Ravenel at Koretzing Cleaners, Wilson, NC. The samples were
analyzed for vinyl chloride, 1 ,1-dichloroethene, cis- and trans-1 , 2-dichloroethene,
trichloroethene, tetrachloroethene, benzene, toluene, ethylbenzene and xylenes.
NELAP Certification
KB Mobile Labs Unit KB2: NCDENR Certification Number 632
PACE Lab: NCDENR Certification Number 12 (% Solids)
Analytical Procedure
All samples were analyzed using SW846 Method 5030/8260 for waters. Ten (10)
milliliters (mL) of water or air (air samples) were purged with helium and the volatile
organic compounds (VOCs) were collected on a solid-phase adsorption trap. The
adsorption trap was heated and back-purged with helium. The components were then
separated by capillary column gas chromatography and measured with a mass
spectrometer (GC/MS) operated in the electron impact full-scan mode. The individual
VOCs in the samples were measured against corresponding VOC standards.
The soil samples were analyzed using SW846 Method 5030/8260. One (1) gram (g) of
soil sample was added to 10 mL of laboratory reagent water, heated and analyzed like a
water sample as described above.
Soil data are corrected for percent solid values supplied by PACE Labs.
Analytical Results
Laboratory results were provided to the client on an as-completed or next-day basis.
Final results of the on-site analyses are provided in a hardcopy report. The data
produced and reported in the field has been reviewed and approved for this final report
by the Director of Operations for KB Labs.

Uncertainty of Reported Values
All measurement data presented in this report are subject to a degree of uncertainty and
the degree of uncertainty varies with each compound of interest. KB Labs estimates the
uncertainty of each measurement using a statistical evaluation of the standard deviation
from the mean percent recovery of a number of trials of a given measurement. More
specifically, KB Labs maintains historical percent recovery control limits at the 99%
confidence level for each analyte of interest. These are calculated as ± 3 times the
standard deviation from the mean of historical measurements of the percent recovery of
spikes of the analytes of interest into actual and control sample matrices. For example,
if the lower and upper percent recovery control limits for a specific analyte of interest
have been determined to be 70 and 100 percent respectively, a reported value of 10.0
ug/L will be with 99% confidence 7.0 to 13.0 ug/L.For more information about KB Labs
estimation of uncertainty, contact KB Labs' quality assurance officer and/or request a
copy of KB Labs' SOP for determining measurement uncertainty.
Quality Control (QC) Data
Surrogate Recoveries — Table 1 lists the daily analytical sequence and percent recovery
results for surrogate compounds, which were added to all analyses. Four (4) surrogate
compounds were added to each analysis in order to continually monitor general method
performance.
VOC Spike Recoveries — Table 2 lists the percent recovery results for matrix spike and
laboratory control samples. A known amount of each target compound was added to
selected field samples and to laboratory reagent water in order to monitor the
performance of each of the target compounds in the actual matrix and in laboratory
reagent water.
Method Blanks — Daily analysis of laboratory reagent water samples was performed in
order to monitor the cleanliness of the analytical system.
DATA REPORT NARRATIVE
1 . All sample data has been reviewed and, if required, updated in the Final Data
Report for rounding, sample weights, and significant figures.

GORETM Surveys - Final Report
ANALYTICAL PROCEDURES
W.L. Gore&Associates' Screening Module Laboratory operates under the guidelines of its
Quality Assurance Manual, Operating Procedures and Methods. The quality assurance program is
consistent with Good Laboratory Practices (GLP) and ISO Guide 25, "General Requirements for
the Competence of Calibration and Testing Laboratories", third edition, 1990.
Instrumentation consists of state of the art gas chromatographs equipped with mass selective
detectors, coupled with automated thermal desorption units. Sample preparation simply involves
cutting the tip off the bottom of the sample module and transferring one or more exposed sorbent
containers (sorbers, each containing engineered adsorbents)to a thermal desorption tube for
analysis. Sorbers remain clean and protected from dirt, soil, and ground water by the
insertion/retrieval cord, and require no further sample preparation.
Analytical Method Quality Assurance:
The analytical method employed is a modified EPA method 8260/8270. Before each run
sequence,two instrument blanks, a sorber containing 51.tg BFB (Bromofluorobenzene), and a
method blank are analyzed. The BFB mass spectra must meet the criteria set forth in the method
before samples can be analyzed. A method blank and a sorber containing BFB is also analyzed
after every 30 samples and/or trip blanks. Standards containing the selected target compounds at
five calibration levels are analyzed at the beginning of each run. The criterion for each target
compound is less than 25%RSD (relative standard deviation). If this criterion is not met for any
target compound,the analyst has the option of generating second- or third-order standard curves,
as appropriate. A second-source reference standard, at a level of 10µg per target compound, is
analyzed after every ten samples and/or trip blanks, and at the end of the run sequence. Positive
identification of target compounds is determined by 1) the presence of the target ion and at least
two secondary ions; 2)retention time versus reference standard; and, 3)the analyst's judgment.
NOTE: All data have been archived. Any replicate sorbers not used in the initial analysis will
be discarded fifteen (15) days from the date of analysis.
Laboratory analysis: thermal desorption, gas chromatography,mass selective detection

GORE Surveys - Final Report
DATA TABULATION
#CONTOUR MAPS ENCLOSED: Three (3) B-sized color contour maps
LIST OF MAPS ENCLOSED:
• Tetrachloroethene(PCE)
• Total target chlorinated compounds
• Total Petroleum Hydrocarbons (TPH)
NOTE: All data values presented in Appendix A represent masses of compound(s)
desorbed from the GORETM Modules received and analyzed by W.L.Gore & Associates,
Inc.,as identified in the Chain of Custody(Appendix A). The measurement traceability and
instrument performance are reproducible and accurate for the measurement process
documented. Semi-quantitation of the compound mass is based on a five-level standard
calibration.
General Comments:
• This survey reports soil gas mass levels present in the vapor phase. Vapors are
subject to a variety of attenuation factors during migration away from the source
concentration to the module. Thus, mass levels reported from the module will often
be less than concentrations reported in soil and groundwater matrix data. In most
instances, the soil gas masses reported on the modules compare favorably with
concentrations reported in the soil or groundwater (e.g., where soil gas levels are
reported at greater levels relative to other sampled locations on the site, matrix data
should reveal the same pattern, and vice versa). However, due to a variety of factors,
a perfect comparison between matrix data and soil gas levels can rarely be achieved.
• Soil gas signals reported by this method cannot be identified specifically to soil
adsorbed, groundwater, and/or free-product contamination. The soil gas signal
reported from each module can evolve from all of these sources. Differentiation
between soil and groundwater contamination can only be achieved with prior
knowledge of the site history (i.e., the site is known to have groundwater
contamination only).
• QA/QC trip blank modules were provided to document potential exposures that were
not part of the soil gas signal of interest (i.e.,impact during module shipment,
installation and retrieval, and storage). The trip blanks are identically manufactured
and packaged soil gas modules to those modules placed in the subsurface. However,
the trip blanks remain unopened during all phases of the soil gas survey. Levels
reported on the trip blanks may indicate potential impact to modules other than the
contaminant source of interest.

GORETM Surveys - Final Report
• Unresolved peak envelopes (LTPEs) are represented as a series of compound peaks
clustered together around a central gas chromatograph elution time in the total ion
chromatogram. Typically, UPEs are indicative of complex fluid mixtures that are
present in the subsurface. UPEs observed early in the chromatogram are considered
to indicate the presence of more volatile fluids, while UPEs observed later in the
chromatogram may indicate the presence of less volatile fluids. Multiple UPEs may
indicate the presence of multiple complex fluids.
• Stacked total ion chromatograms (TICs) are included in Appendix A. The six-digit
serial number of each module is incorporated into the TIC identification (e.g.:
123456S.D represents module#123456).
Project Specific Comments:
• The minimum (gray) contour level, for each mapped analyte or group of analytes,
was set at the maximum blank level observed or the method detection limit,
whichever was greater. When target compounds are summed together(i.e., Total
target chlorinated compounds), the contour minimum is arbitrarily set at 0.02 µg or
the maximum blank level, whichever is greater. The maximum contour level was set
at the maximum value observed.
• No target compounds were detected on the trip blanks and/or the method blanks.
Thus, target analyte levels reported for the field-installed modules that exceed trip
and method blank levels, and the analyte method detection limit, are more likely to
have originated from on-site sources.
• The mapped spatial patterns showed detections of TPH throughout the study area.
Highest levels of TPH were detected at module 547655 in the lower (southern)
portion of the study area. Highest levels of PCE and total chlorinated compounds
were detected at module 547625 in the upper(north) central section of the survey
area.
• If the objective of the soil gas survey was to delineate the nature and extent of the
contamination, then additional soil gas sampling is recommended in those areas
where the color contours appear to extend into unsampled areas. Subsequent
sampling events can be combined with the data from this event and mapped together
to provide greater coverage.

North Carolina Aquifers
The aquifers in North Carolina are highly varied in their character and water producing capabilities. Several
of these aquifers can be traced over large geographic areas and hence form principal aquifers; significant
sources of ground water for potable water supplies and other agricultural or industrial interests in large
portions of North Carolina. Other aquifers in the State provide less significant amounts of water and cover
smaller areas of the State. The following material describes briefly some attributes of the principal aquifers,
which include the lower Cape Fear, upper Cape Fear, Black Creek, Peedee, Castle Hayne, Yorktown,
Surficial, and Bedrock aquifers. Minor aquifers in the State include the lower Cretaceous, Beaufort, and
Pungo River.
Aquifers, or more accurately, aquifer systems, are hydraulically connected materials (sands, limestone,
and fractured rock) that provide water through a properly constructed well open to those materials. In the
coastal plain, an aquifer is typically composed of one to several layers of eastward thickening, permeable
sands or limestone split by discontinuous, clay-rich materials. Confining units, consisting of clay-rich
sediments, exist above and below an aquifer. These confining units are more continuous clay layers and
separate the aquifers. The surficial or unconfined aquifer overlies all the confined aquifers in the coastal
plain.
In the Piedmont and Blue Ridge Provinces of North Carolina, two major aquifer systems exist, and usually
interact with one another. The surficial materials or regolith of these provinces forms the unconfined
aquifer and the fractured rock beneath, is the unconfined to semi-confined bedrock aquifer. Usually the
surficial aquifer feeds the fractures in the bedrock aquifer.
Several of the principal aquifers deserve further classification. The upper and lower Cape Fear, Black
Creek, Peedee, and Castle Hayne aquifers form regional aquifers. In large portions of these aquifers,
sands and limestone materials are so well connected that withdrawals cause pressure reductions many
miles from the pumping center. This is good news in that wells are very high yielding. The negative
outcome is that pumping at one well affects water levels in wells for miles around. This can be seen in
water level data from the central coastal plain in the upper Cape Fear, Black Creek, and Peedee aquifers;
Robeson, Bladen and Columbus counties in the upper Cape Fear aquifer; northeastern North Carolina in
the lower Cape Fear aquifer; and Beaufort and surrounding counties in the Castle Hayne aquifer.
The following correlation chart illustrates the relation between North Carolina coastal plain aquifers,
geologic time, geologic formations, and similar information from South Carolina and Virginia.

Principal Aquifers (links tm` the latest potentiometric surface maps available)
Historical potentiometric surface maps for the regional aquifers can beseen here.
* Lower Cape Fear mnvife/: This aquifer is present in the northwestern portion of the coastal plain at elevations nf'
A to-2325faet. averaging -500 feet(referenced to mean sea level). The lower Cape Fear aquifer ranges from
20 to 1487 feet thick and averages about 300 feet thick. The aquifer is composed of fine to coarse sands. Wells
typically yield 200'400 gallons per minute.
* Upper Cape FnuroquiYe': This aquifer is present in the vveuiem portions of the nueaio| plain at elevations of285
to-1519 feet, averaging -250 feet. The upper Cape Fear aquifer ranges from 8 to 665 feet thick and averages
about 150 feet thick. The aquifer is composed of very fine to coarse sands and occasional gravels. Wells
typically yield 200'400 gallons per minute.
w Black Crook aquifer, This aquifer is present in the central and southwestern portions of the coastal plain at
elevations of 317 to-1207 feet, averaging -135 feet. The Black Creek aquifer ranges from 18 to 972 feet thick
and averages about 175 feet thick. The aquifer is composed of very fine to fine "salt and pepper"sands. Wells
typically yield 2UU-4O0 gallons per minute.
m Pe*dww aquifer- This aquifer is present in the central to southeastern portion of the 0000b| plain at o|oveUona of
114 to-796 feet, averaging -30 feet.The Peedee aquifer ranges from 8 to 404 feet thick and averages about
135 feet thick. The aquifer is composed of fine to medium sand. Wells typically yield upto2O0 gallons per
minute.
* Cwmdw Mayne aquifa/: This aquifer is widely used in the eastern portions of the unmotm| plain at elevations of65
to'O7O feet, averaging -QO feet. The Castle Hoyno aquifer ranges from 15tnO54 feet thick and averages about
175 feet thick. The aquifer is composed of limestone, sandy|imeotono, and sand. It is the most productive
aquifer in North Carolina. VVo||u typically yield 200-500 gallons per minute, but can exceed 2000 gallons per
minute.
w Yorktown aquifer: This aquifer in present throughout most of the northern coastal plain at elevations ranging
from 1O0to-285 feet, averaging -3feet. The Yorktown aquifer ranges from 4to709 feet thick and averages
about 75 feet thick. Several localities tap this aquifer and produce high yielding wells including Roanoke Island,

Aquifer Characteristics Page 3of4
Kill Devil Hills, and Elizabeth City. Yorktown aquifer is composed of fine sand, silty and clayey sand, shell beds,
and coarser sand beds. Wells typically yield 15-QO gallons per minute.
w surficiall aquifer: This aquifer is widely used throughout the State for individual home wells. The sufficial
aquifer is the shallowest and most susceptible to contamination from septic tank systems and other pollution
sources. Commonly, large diameter wells (up to 3 feet in diameter) are drilled up to 60 foot deep to store large
quantities of water in the well casing.The surficial aquifer is also very sensitive to variations in rainfall amounts
-they are the first to dry-up in a drought. On the Outer Banks shallow wells are subject to rainfall amounts,
saltwater intrusion, poor quality ground water, and ocean overwash. Wells typically yield 25-200 gallons per
minute.
• Fractured Bedrock aquifer: This aquifer iowidely used for home water supply in the western coastal p|oin.
Piedmont. and Blue Ridge Provinces. Usually six inch wells are drilled to intercept water bearing fractures which
are more common in valleys or draws. Thick sequences of regolith (surficial aquifer) above fractured bedrock
can improve yields to 200 gallons per minute or more. industries and county or municipal well fields look for
these higher yielding bedrock wells.Wells typically yield 5-35 gallons per minute.
Minor Aquifers
~ lower Cretaceous aquifer: This aquifer is rarely used. It is only fresh in the northern part of the coastal plain
below Hartford and Northhemphon Counties. The top of this aquifer occurs at elevations of355 to'2287 feot,
averaging -1135 feet. The lower Cretaceous aquifer ranges from 25 to 812 feet thick and averages about 4O7
feet thick. The aquifer consists of fine to medium sand with occasional coarse sand and limestone beds.
* Beaufort aquifer: This aquifer)n present inthe eastern-central portion cf the coastal plain a1 elevations of22Vu
-1207 feet, averaging -237 feet. The Beaufort aquifer ranges from 4 to 148 feet thick and averages about 49
feet thick. This aquifer is composed of fine to medium glauconitic sand, clayey sand, with occasional shell and
limestone beds.
w Pungo River aquifer: This aquifer is present in the north-central coastal plain at elevations of'2OUm '617feet,
averaging -186 feet.The Pungo River aquifer ranges from 6 to 225 feet thick and averages about 56 feet thick.
The aquifer consists of fine bo medium sand.

Approximate recharge areas for some of these aquifers are to be shown on a recharge map that is under
construction.
Aquifer recharge areas indicate where the respective aquifer may be recharged by the surficial aquifer.
Local conditions may not allow recharge to confined aquifers. Please refer to the typical water budget for the
NC coastal plain. As is clear in this budget diaQnanm, a very small peroentago of rainfall infiltrates into the
confined aquifer system. Most rainfall is lost to evapotranspiration, nunoff. Or infiltrates into the aha||ovv
ground water system then discharges to local rivers and streams. This discharge to surface drainage is
commonly referred to as "base flow."
Those aquifers not shown are recharged laterally 0[ by vertical movement through leaky confining units.

Instructions: Brief description of all significant events that have occurred since a problem was
Date suspected at the facility. Commence with the first date a problem was suspected and continue
through the most recent activity described in the current report.
Turner Environmental Consultants,PC advanced six soil borings inside the building of the former Koretizing Cleaners.
1997 Soil sample analytical results indicated PCE concentrations as high as 6,860 mg/kg. One groundwater sample was
collected from a temporary well located approximately 70 feet west of the former dry cleaner. Groundwater analytical
results identified PCE and vinyl chloride above their respective 2L Standards.
Arcadis,Geraghty,&Miller completed an"Initial Soil and Groundwater Investigation." Ten soil borings were advanced
to the top of the water table,which ranged from 4 to 6 feet bgs. Soil sample results indicated PCE concentrations above
September 1998 the Soil Concentration Protective of Groundwater. Five shallow temporary piezometers were installed and sampled. One
deeper well was installed to 32 feet bgs. PCE was not detected in any of the groundwater samples,but several daughter
chlorinated compounds were detected above 2L Standards.
Arcadis completed a"Comprehensive Site Assessment"in December 1999. No water supply wells were identified within
1,500 feet of the site. Seven Type II monitoring wells and two Type III monitoring wells were installed and sampled.
December 1999 Concentrations of chlorinated solvents were detected above 2L standards. Arcadis supervised soil excavation activities
inside the building. Base and sidewall samples indicated no impact to the remaining soils post excavation,but one floor
sample from the excavation exceeded the DSCA SCPG.
September 2001 Arcadis completed a"Groundwater Assessment Report"in September 2001. The existing monitoring wells were
sampled. Groundwater analytical results indicated PCE concentrations above 2L standards in five monitoring wells.
Withers&Ravenel completed a"Priority Assessment Report"in April 2007. The assessment included a receptor survey,
installation and sampling of one additional Type II monitoring well and sampling 8 existing monitoring wells. An
April 2007 apparent private WSW was identified approximately 830 feet east of the site,and an irrigation well was observed at a
public baseball park approximately 1500 feet east of the site. Groundwater analytical results indicated PCE and PCE
daughter compounds at concentrations above 2L standards.
Withers&Ravenel completed a"Groundwater Assessment/Monitoring Report"in August 2007. Fourteen additional
Type II monitoring wells were installed and sampled,and ten existing monitoring wells were sampled. PCE and/or PCE
August 2007 daughter products were identified at concentrations above the 2L standards. Benzene was also detected above 2L
standards in some wells,likely from the two adjacent gas stations. The results of this sampling event were consistent with
the results of the February 2007 sampling event.
January 2008 Withers&Ravenel installed 35 GORE Module soil gas samplers. The analytical results indicated PCE and PCE
daughter products were detected in the soil gas from two of the 35 sample locations.
Withers&Ravenel installed 16 temporary monitoring wells. Samples were collected from each temporary well and
analyzed onsite by a mobile. W&R used these results to determine the locations of five new Type II monitoring wells.
April 2008 All other existing monitoring wells were sampled and analyzed by the mobile lab. Five soil borings were conducted along
the storm sewer line running through the subject property. The soil samples were below laboratory detection limits for all
chlorinated VOCs.
