1.0 INTRODUCTION
In accordance with Vapor Intrusion Assessment Work Plan (Work Plan) dated July 21,
2015, Mid -Atlantic Associates, Inc. (Mid -Atlantic) has prepared this Vapor Intrusion
Assessment Report for the property located at 810 Lufkin Road in Apex, Wake County,
North Carolina (Drawing 1). The Work Plan was approved by the North Carolina
Department of Environment and Natural Resources (NCDENR) Brownfields Program
approved the Work Plan via email on July 22, 2015.
2.0 SUMMARY OF SAMPLING ACTIVITIES
2.1 Sub -Slab Soil Gas Sampling Activities
On July 29, 2015, Mid -Atlantic mobilized to the subject site to collect one sub -slab soil gas
sample. As described in the Work Plan, the soil gas sample location was selected to
evaluate soil gas in an area where solvent —impacted soil has been excavated previously
from a former storage room (Drawing 2). A vapor pin was installed in the ground floor slab
for use as a sampling port. The vapor pin is an air tight barbed fitting used for collection of
sub -slab soil gas samples. The soil gas sample was collected using stainless steel "Mini-
SUMMA" canister at a flow rate of 200 mL/min. For quality assurance purposes, leak
checks were performed prior to sample collection using helium tracer gas, a shroud over
the sample probe site, and a portable helium detector. The soil gas sample was submitted
under chain -of -custody from the subject site to Con -Test Analytical Laboratory in East
Longmeadow, Massachusetts for analysis by EPA Compendium Method TO-15.
2.2 Indoor Air Sampling Activities
On July 29, 2015, Mid -Atlantic mobilized to the subject site to deploy Radiello samplers as
described in the Work Plan. A total of 13 samplers were placed including 10 indoor air
samplers, one duplicate and two ambient air samplers. The sample locations are illustrated
in Drawing 2. The Radiello samplers were either placed on tripods (manufacturing area) or
suspended from the ceiling (office area) to locate them between three and six feet off the
floor. The ambient air sample to the southwest was mounted to a fence and the ambient
air sampler to the northwest was hung from a tree. Both of the ambient air samples were
protected from rain by a plastic rain shield. Mid -Atlantic returned to the subject site to collect
the Radiello samplers on August 6, 2015. The Radiello samplers were submitted under
chain -of -custody from the subject site to Con -Test Analytical Laboratory in East
Longmeadow, Massachusetts for analysis of 1,1-dichloroethylene, trichloroethylene,
tetrachloroethylene and cis- 1,2-dichloroethylene by EPA Compendium Method TO-15.
3.0 SUMMARY OF LABORATORY TEST RESULTS
The laboratory analytical report and chain -of -custody records for the samples collected at
the site are provided in Appendix A.
Twenty four compounds were detected in the sub -slab soil gas sample collected from the
former storage room and tested by EPA Method TO-15. However, no compounds were

detected in a concentration that exceeds NCDENR Division of Waste Management (DWM)
default non-residential or residential sub -slab screening levels (TCR=1.0E-05; HQ=0.2).
Sub -slab soil gas results are summarized in Table 1.
The compounds 1,1-dichloroethylene and cis-1,2-dichloroethylene were not detected in
any of the 13 indoor/ambient air samples collected. Tetrachloroethene was detected in
each indoor air sample (11) at a concentration that exceeds DWM default residential
screening levels for indoor air. The concentration of tetrachloroethene at each of these
sample locations did not exceed the DWM default non-residential screening levels for indoor
air. The average concentration of tetrachloroethene in the indoor air samples was 12.2
ug/m3 with a range of 8.4 to 17 ug/m3 (including the duplicate sample). Tetrachloroethene
was also detected in one of the ambient air samples. The southwest ambient air sample
contained 13 ug/m3 tetrachloroethene. Notably, this concentration is similar to the average
detected in the indoor air samples. Tetrachloroethene was not detected in the northwest
ambient air sample.
An evaluation of wind related meteorological data recorded at Raleigh Durham Airport
was conducted. The data evaluated included the direction of the fastest 5-second and the
fasted 2-minute winds recorded. Over the eight days the samplers were deployed, these
wind directions were southwest on five days, northeast on two days and west on one day.
This data suggests that the southwest ambient air sample location was upwind of the
subject site building for five of the eight sampling days.
Trichloroethene was detected in concentrations exceeding DWM default residential
screening levels in three samples (IA-5, it's duplicate and IA-8). At one location (IA-5, two
samples since this was the duplicate location). trichloroethene was detected in a
concentration that exceeds the DWM default non-residential screening level for indoor air.
This sample location is in a former exercise room located in the northeast corner of the
building. This location is in close proximity to a dissolved solvent plume, which contains
trichloroethene among other compounds, emanating from the property adjacent to the north
of the subject site. Trichloroethene was not detected in either of the ambient air samples.
The residential indoor air sample cumulative target non -cancer hazard index (1­1I=1) was
exceeded in samples IA-5 and duplicate (HI=1.6 and 1.7 respectively) and IA-8 (HI=1.2). If
PCE detections were not included in risk calculations, only sample IA-5 and duplicate
(HI=1.3 and 1.4 respectively) exceeded the target non -cancer hazard index (1­1I=1).
The non-residential indoor air sample cumulative target non -cancer hazard index (HI=1) was
not exceeded in any sample.
The sample sum target cancer risk (TCR) =1.0E-05 was not exceeded in any of the
samples for residential or non-residential environments. The residential sample sum
target cancer risk (TCR) =1.0E-06 was exceeded for all indoor air samples except IA-6,
IA-7 and IA-10; and for ambient sample AA-1. If PCE detections were not included in risk

calculations, the residential sample sum target cancer risk (TCR) =1.0E-06 was exceeded
only for sample IA-5 and its duplicate.
The non-residential sample sum target cancer risk (TCR) =1.0E-06 was exceeded only
for sample IA-5 and its duplicate. If PCE detections were not included in risk calculations,
the residential sample sum target cancer risk (TCR) =1.0E-06 was exceeded only in the
IA-5 duplicate sample.
4.0 CONCLUSIONS
The assessment of the sub -slab soil gas under the former storage room does not indicate
presence of any EPA TO-15 Compendium compounds in concentration exceeding DWM
soil gas screening levels (residential or non-residential).
Tetrachloroethene was detected in each of the indoor air samples collected as well as in the
upwind ambient sample location. The concentration of tetrachloroethene at all of these
locations (including ambient air AA-1, the upwind ambient air sample) exceeds the DWM
default residential screening levels for indoor air, but are below the non-residential screening
levels for indoor air. The data does not suggest an amplification of tetrachloroethene when
comparing the upwind ambient air sample concentration to the average concentrations
recorded in the building. The source of the detected tetrachloroethene is not known, but the
data does not indicate that the tetrachloroethene detected inside the building is the result of
vapor intrusion from a subsurface source.
The data show that the trichloroethene concentration in a sample collected from the former
exercise room (IA-5 and its duplicate) exceeds the indoor air screening level for residential
indoor environments at Hazard Index =1. The prior use of this area as an exercise room
suggests that interior source of the trichloroethene is unlikely. This sample location is also
in close proximity to a groundwater solvent plume emanating from the neighboring property
to the north. This solvent plume contains trichloroethene as well as other chlorinated
solvents. Trichloroethene was detected in one other sample (IA-8) at a concentration
exceeding residential, but not non-residential, DWM default indoor air screening levels. The
data suggest that vapor intrusion of trichloroethene may be occurring at the subject site.

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-03 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this
compound is likely to be biased on the low side.
V-05 Continuing calibration did not meet method specifications and was biased on the low side for this compound.
Increased uncertainty is associated with the reported value which is likely to be biased on the low side.

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 1,1-dichloroethene, trans-1,2-dichloroethene, and cis-1,2-dichloroethene are estimated
using Graham's Law and are as follows: 1, 1 -dichloroethene = 83 mL/min, trans-1,2-dichloroethene = 83 mL/min, cis-1,2-dichloroethene = 83 mUrnin.
The results for these 3 compounds are estimated values.
RAD 130
Qualifications
Continuing calibration did not meet method specifications and was biased on the high side for this compound. Increased uncertainty is
associated with the reported value which is likely to be biased on the high side.
Analyte & Samples(s) Qualified:
Trichloroethene
15H0442-05[IA-5], 15H0442-06[IA-6], 15H0442-08[IA-8], 15H0442-13[Dup-1], B129049-BSI, B129049-BSDI
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.
