Re: Indoor Air, Soil Gas, and Groundwater Sampling Report
American Dry Cleaners DSCA Site ID #DC680002
201 South Estes Drive, Chapel Hill, Orange County, North Carolina
Dear Mr. Cunningham:
AECOM Technical Services of North Carolina, Inc. (includes legacy URS and legacy AECOM herein
referred to as AECOM) is pleased to provide the attached Indoor Air, Soil Gas, and Groundwater
Sampling Report for the American Dry Cleaners (#DC680002) site located at 201 South Estes Drive,
Chapel Hill, North Carolina.
This report includes documentation pertaining to the indoor air and soil gas sampling activities that were
completed at the site in June and December 2018, as well as follow-up indoor air sampling events
completed in January and February 2019. In addition to the soil gas and indoor air sampling activities,
this report also includes the findings of a limited groundwater sampling event completed in December
2018. The activities documented herein were completed in accordance with State Lead Authorization for
Work (SLAW) 027, as approved on February 9, 2018, and change order 027A, approved on January 31,
2019.
Due to the potential risk of vapor intrusion from tetrachloroethene (PCE) contaminated groundwater to
affect indoor air quality at the western portion of the Olin T. Binkley Church, periodic monitoring of soil
gas and indoor air quality was implemented in June 2017. This included the installation and sampling of
two permanent soil gas sampling points (SV-5 and SV-6) at the locations shown on Attachment 14.
Comprehensive information specific to the installation and initial sampling of soil gas sampling points
SV-5 and SV-6 in December 2016 is on file in the Groundwater and Vapor Monitoring Report, dated
January 18, 2018.
Pursuant to SLAW 027, soil gas sampling points SV-5 and SV-6 were sampled on June 15, 2018, and
December 19, 2018. During both sampling events soil gas sampling point SV-6 produced moisture in the
tubing indicating that the soil gas sampling point was most likely flooded from infiltrate from the surface.
AECOM plans to reinstall soil gas sampling point SV-6 during the June 2019 sampling event. The soil
gas samples collected from SV-5 were analyzed for five DSCA contaminants of concern: PCE,
trichloroethene (TCE), cis-1,2-dichloroethene (DCE), trans-1,2-DCE, and vinyl chloride using EPA
Method TO-15 LL. A summary of the soil gas quality results, as entered into the DSCA risk calculators,
is provided as follows:
SV-5 (6/15/18) — non-residential worker
o Unacceptable cumulative carcinogenic risk of 1.6E-04; and,
o Unacceptable hazard index of 54.
SV-5 (6/15/18) - resident
o Unacceptable cumulative carcinogenic risk of 2.9E-03; and,
o Unacceptable hazard index of 680.

SV-5 (12/19/18) — non-residential worker
o Unacceptable cumulative carcinogenic risk of 1.1E-04; and,
o Unacceptable hazard index of 34.
SV-5 (12/19/18) - resident
o Unacceptable cumulative carcinogenic risk of 1.8E-03; and,
o Unacceptable hazard index of 430.
Permanent soil gas points SV-5 and SV-6 were installed to monitor soil gas in relation to indoor air
concentrations. Since SV-5 was installed in June 2017, concentrations of PCE have increased from
75,000 micrograms per liter (µg/m3) to 120,000 µg/m3 in December 2018. TCE concentrations have
remained steady ranging from 24,900 µg/m3 to 24,000 µg/m3, with the exception of June 2018 at 40,000
µg/m3. Due to water in the tubing during the June and December 2018 sampling events, limited data are
available for SV-6. Concentrations of PCE have increased from 3,850 µg/m3 to 21,000 µg/m3 in between
June and December 2018. TCE concentrations increased from 484 µg/m3 to 3,300 µg/m3 between June
and December 2018.
As part of continued evaluation of potential vapor intrusion risk to the preschool located at the Olin T.
Binkley Church, two indoor air samples (IA-2 and IA-3) were collected concurrent with the soil gas
samples in June and December 2018. Each indoor air sample was collected using a passive Radiello
sampler deployed for a period of 7 days from within the preschool located at the Olin T. Binkley Church.
Sampling results and locations are shown on Attachment 14. A summary of the indoor air quality results,
as entered into DSCA risk calculators, is provided as follows:
• IA-2 (6/8/18 - 6/15/18) — non-residential worker
o Acceptable cumulative carcinogenic risk of 5.9E-08; and,
o Acceptable hazard index of 0.016.
• IA-2 (6/8/18 - 6/15/18) - resident
o Cumulative carcinogenic risk less than 1E-06 (2.6E-07); and
o Cumulative hazard index is less than 1 (0.067).
• IA-2 (12/14/18 - 12/21/18) - non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (7.3E-07); and
o Cumulative hazard index is less than 1 (0.24).
• IA-2 (12/14/18 - 12/21/18) - resident

IA-3 (12/14/18 - 12/21/18) - resident
o Cumulative carcinogenic risk is between 1E-05 and 1E-06 (4.9E-06); and
o Cumulative hazard index is greater than 1 (1.1).
The analytical results of the December 2018 sampling event indicated an exceedance of acceptable risk
for residential exposure, as calculated using the DSCA Risk Calculator. AECOM discussed the
December 2018 indoor air sampling results with Mr. Mike Cunningham of DSCA, and recommended to
immediately resample the designated indoor air sampling locations to confirm if the December 2018
indoor air sampling data was representative of actual indoor air quality or possibly attributable to
extraneous factors such as fugitive emissions from products containing similar contaminants, and/or
materials introduced into the vicinity of the sample locations. Two indoor air samples (IA-2 and IA-3)
were collected in January and February 2019 using 7-day Radiello samplers. A summary of the indoor air
quality results, as entered into DSCA risk calculators, is provided as follows:
• IA-2 (1/11/19 - 1/18/19) — non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (5.9E-07); and
o Cumulative hazard index is less than 1 (0.2).
• IA-2 (1/11/19 - 1/18/19) - resident
o Cumulative carcinogenic risk between 1E-05 and 1E-06 (3.6E-06); and
o Cumulative hazard index is less than 1 (0.83).
• IA-2 (2/8/19 - 2/15/19) - non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (5.9E-07); and
o Cumulative hazard index is less than 1 (0.2).
• IA-2 (2/8/19 - 2/15/19) - resident
o Cumulative carcinogenic risk between 1E-05 and 1E-06 (3.6E-06); and
o Cumulative hazard index is less than 1 (0.83).
• IA-3 (1/11/19 - 1/18/19) - non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (5.2E-07); and
o Cumulative hazard index is less than 1 (0.17).
• IA-3 (1/11/19 - 1/18/19) - resident
o Cumulative carcinogenic risk between 1E-05 and 1E-06 (3.1E-06); and
o Cumulative hazard index is less than 1 (0.73).
• IA-3 (2/8/19 - 2/15/19) - non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (5.7E-07); and
o Cumulative hazard index is less than 1 (0.19).
• IA-3 (2/8/19 - 2/15/19) - resident
o Cumulative carcinogenic risk is between 1E-05 and 1E-06 (3.5E-06); and
o Cumulative hazard index is less than 1 (0.81).
In addition to the collection of the Radiello samples deployed over a duration of seven days, AECOM
deployed two 8-hour summa samples (IA-2 [8-hr] and IA-3 [8-hr]) within the two designated indoor air
sampling locations on January 11, 2019. Results from the January 2019 re -sampling were received by
AECOM on January 24, 2019, and indicated that contaminant concentrations were lower than that
observed in December 2018 and within acceptable calculated risk levels for residential exposure. Results
are shown on Attachment 14. A summary of the indoor air quality results, as entered into DSCA risk
calculators, is provided as follows:

• IA-2 (1/11/19) — non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (8.OE-08); and
o Cumulative hazard index is less than 1 (0.025).
• IA-2 (1/11/19) - resident
o Cumulative carcinogenic risk less than 1E-06 (4.4E-07); and
o Cumulative hazard index is less than 1 (0.11).
• IA-3 (1/11/19) - non-residential worker
o Cumulative carcinogenic risk less than 1E-06 (TOE-08); and
o Cumulative hazard index is less than 1 (0.022).
• IA-3 (1/11/19) - resident
o Cumulative carcinogenic risk less than 1E-06 (3.8E-07); and
o Cumulative hazard index is less than 1 (0.091).
When comparing the 8-hour summa samples to the Radiello samples, concentrations of PCE and TCE are
generally similar. Overall, PCE and TCE concentrations from the summa samples are slightly lower
relative to the concentrations of the Radiello samples. Indoor air sampling results are summarized on
Attachment 14.
On December 19, 2018, AECOM performed a limited groundwater sampling event pursuant to work
authorized under SLAW027, dated February 9, 2018. Sampling was completed using standard purge and
sample techniques, in accordance with standard purge methods. An updated potentiometric surface
contour map using depth to water levels gauged on December 19, 2018, is included as Attachment 6.
Laboratory analysis of the groundwater samples indicated the presence of chlorinated volatile organic
compounds (CVOCs) above NC 2L Groundwater Quality Standards in monitoring wells MW-2, 2W-9,
2W-10, and 2W-11. A groundwater quality summary map is included as Attachment 7. Groundwater
analytical data is summarized in ADT Table 8.
During the December 2018 groundwater sampling event, an older monitoring well installed by Withers
and Ravanel (2W-8) was observed to be damaged. Monitoring well 2W-8 is located within the entryway
to the shopping center and is north of the contaminant plume. The well has been sampled two times
(December 2007 and November 2013), with only a trace level of TCE (0.00032 J micrograms per liter)
detected during the November 2013 sampling event. The well appeared to be filled with sediment and a
water level meter could not be advanced down the well likely indicative of a cracked PVC casing.
AECOM recommended to DSCA that this well should be properly abandoned in order to reduce the
likelihood of storm water impacts to the monitoring well and comply with NCAC 2C guidelines. On
February 14, 2019, 2W-8 was abandoned by Regional Probing Services, a North Carolina Licensed Well
Driller. The well abandonment record is included as Attachment 5.
According to the Mann -Kendall Trend Analysis worksheets, included in Attachment 18, concentrations
of PCE are stable in monitoring well MW-2, and decreasing in monitoring wells 2W-9, 2W-10, and 2W-
11. Additionally, concentrations of TCE are stable in monitoring well MW-2, decreasing in 2W-9, and
demonstrate no trend in 2W-10 and 2W-11. Concentrations of PCE and TCE indicated groundwater
concentrations continue to decrease during the December 2018 sampling event.
As documented above, soil gas contaminant concentrations continue to present an unacceptable
cumulative carcinogenic risk and hazard index, the indoor air samples collected in June 2018were within
acceptable residential exposure ranges. The December 2018 indoor air samples indicated an exceedance

of residential risk. Two additional indoor air sampling events were completed in January 2019 and
February 2019 to determine if concentrations remained above acceptable risk levels. Both confirmatory
sampling events indicated indoor air concentrations of PCE and TCE had slightly decreased, and
acceptable risk levels for residential use. Due to the continued potential risk of vapor intrusion,
semiannual indoor air sampling and soil gas sampling should continue in 2019.
The work was done in accordance with AECOM Contract N16004, dated January 3, 2017, and in
accordance with the scope and estimates provided in the approved SLAW027. If you have any questions
or require additional information, please do not hesitate to call either Rob MacWilliams at 704-499-4839

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 mL/min. The theoretical sampling rates for vinyl chloride, trans-1,2-dichloroethene, and cis-1,2-dichloroethene are estimated
using Graham's Law and are as follows: vinyl chloride = 103 mL/min, trans-1,2-dichloroethene = 83 mL/min, cis-1,2-dichloroethene = 83 mL/min. The
results for these 3 compounds are estimated values.
EPA TO-15
Qualifications
Elevated reporting limit due to high concentration of target compounds.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.

A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.

For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 mL/min. The theoretical sampling rates for vinyl chloride, 1, 1 -dichloroethene, trans-1,2-dichloroethene, and
cis-1,2-dichloroethene are estimated using Graham's Law and are as follows: vinyl chloride = 103 mL/min, 1, 1 -dichloroethene = 83 mL/min,
trans-1,2-dichloroethene = 83 mUmin, cis-1,2-dichloroethene = 83 mL/min. The results for these 4 compounds are estimated values.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 mL/min. The theoretical sampling rates for vinyl chloride, trans-1,2-dichloroethene, and cis-1,2-dichloroethene are estimated
using Graham's Law and are as follows: vinyl chloride = 103 mL/min, trans-1,2-dichloroethene = 83 mL/min, cis-1,2-dichloroethene = 83 mL/min. The
results for these 3 compounds are estimated values.
The results of analyses reported only relate to samples submitted to the Con -Test Analytical Laboratory for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 mL/min. The theoretical sampling rates for vinyl chloride, trans-1,2-dichloroethene, and cis-1,2-dichloroethene are estimated
using Graham's Law and are as follows: vinyl chloride = 103 mL/min, trans-1,2-dichloroethene = 83 mL/min, cis-1,2-dichloroethene = 83 mL/min. The
results for these 3 compounds are estimated values.
The results of analyses reported only relate to samples submitted to the Con -Test Analytical Laboratory for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.
