1.0 SITE DESCRIPTION
The site is located at 527 Atando Avenue in Charlotte, North Carolina and consists of an
approximate 4-acre parcel located in an industrial area (Mecklenburg County Tax Parcel ID
08505412). The single-story industrial building at the site includes a 7,546 square foot (sq. ft.)
office area with adjacent warehouse and production areas totaling approximately 97,211 sq. ft.
The site is bound to the southwest by railroad tracks, to the northwest and southeast by adjacent
industrial facilities, and to the northeast by Atando Avenue. Current and historical occupants of
the on-site facility are suppliers of steel bar stock. The site is currently within the North Carolina
Brownfields Program as a result of contamination detected on the property. Redevelopment plans
will be focused on the southern warehouse area although detailed plans are not available. A
topographic map showing the site location is included as Figure 1 and a site layout map with
general site features is included as Figure 2.
Groundwater flow direction at the site is generally towards the south and southeast. Groundwater
impacts have been detected in two localized areas at the site. One area of volatile organic
compound (VOC) impacted groundwater has been identified along the northern property
boundary. The source of these chlorinated VOCs is believed to be an off-site facility located on
the adjacent property to the north.
A second area of impacted groundwater is located beneath the southern warehouse area.
Groundwater impacts in this area are related to a release of petroleum constituents from one or
two leaking underground storage tanks that were formerly located beneath the warehouse floor
slab. It is our understanding that regulatory oversight of the petroleum release area will continue
to be conducted by the NCDEQ UST Section, and not the Brownfields Program. A site layout
map depicting the building footprint, monitoring well locations and other site features is included
as Figure 2.
In November 2015, Terracon collected four sub-slab soil vapor samples at the site. Two of the
samples contained VOCs exceeding the applicable Residential Sub-Slab and Exterior Soil Gas
Screening Levels (SGSLs) established by the NCDEQ Division of Waste Management, updated
September 2015. One of the samples collected in the northern warehouse/manufacturing area
had vapor constituent concentrations exceeding the Non-Residential SGSLs. One indoor air and
one outdoor air sample were collected concurrently with the sub-slab soil vapor samples. The
indoor air sample (IA-01, collected in the safe room/break room area) contained naphthalene

exceeding the Non-Residential Indoor Air Screening Level (IASL) and benzene and chloroform
exceeding their respective Residential IASLs.
In response to Terracon’s Limited Site Investigation Report, Ms. Carolyn Minnich of the North
Carolina Brownfields Program requested on January 19, 2016, that as many as three rounds of
additional indoor air samples should be collected at the site to evaluate impacts from
contaminants within the groundwater at the site. The first indoor air sampling event was conducted
on February 24, 2016. The investigation discussed in this report was designed to meet the
requirements for the second (August 2016) of three indoor air sampling events.
2.0 SCOPE OF SERVICES
2.1 Indoor and Outdoor Air Sample Collection
Prior to sample collection, Terracon personnel visited the site to provide the building tenant with
the Instructions for Occupants - Indoor Air Sampling Events summary document as suggested in
the DWM Vapor Intrusion Guidance. Air samples were proposed and collected at the following
locations:
§IA-02 in the currently occupied office area
§IA-03 in the former locker room that is now used as a hallway
§IA-04 in the production warehouse where steel bars are cut, stored and loaded onto trucks
§IA-05 in the production warehouse near former sub-slab sample SV-04 where
tetrachloroethene was present above the Non-Residential SGSL.
§IA-06 in the southern warehouse area that is currently unoccupied. This is where two
former USTs were located.
§DUP-01-07132016 – a duplicate indoor air sample collected at IA-02 for QA/QC purposes.
§OA-02 (outdoor air) near the fence along the eastern site boundary to evaluate
background air concentrations.
§OA-03 (outdoor air) near the western exterior wall of the workshop area.

3.0 FIELD INVESTIGATION METHODS
3.1 Indoor and Outdoor Air Sampling
As part of the air sample collection process, Terracon completed an Indoor Air Building Survey
and Sampling Form by interviewing Mr. Frank Anzur with Sunbelt-Turret (on-site tenant) on
August 18, 2016. The survey identified a canister used for storing heating oil in the southern
warehouse area. The canister was removed prior to indoor air sample collection. Terracon also
provided Mr. Anzur a summary sheet with information on indoor/outdoor air sampling for the on-
site workers. Sample locations are shown on Figure 2.
Air sampling was conducted on August 18, 2016 in general agreement with the DWM Vapor
Intrusion Guidance. Five indoor air samples and two outdoor air samples were collected to assess
the presence of VOCs in ambient air within the building. The indoor air sample canisters were
located in such a way that they did not interfere with the activities of the workers on the site and
each sample intake was at the general breathing height (approximately 3 to 5 feet above ground

surface). The outdoor air samples were collected on the eastern site boundary towards Atando
Avenue (OA-02) and along the western exterior wall of the workshop area (OA-03).
The air samples were collected in laboratory supplied 6-liter Summa canisters attached to a flow
controller set for 8 hours. Terracon personnel remained on the site during sample collection and
recorded the residual vacuum for each of the 8 sample canisters (including one blind duplicate
sample collected at location IA-02 in addition to the primary sample for QA/QC purposes) on an
approximate hourly basis. A sampling and analysis plan is provided as Table 1.
Following completion of the field activities, the Summa canisters (8 canisters/samples), along with
chain-of-custody documentation, were shipped to Eurofins AirToxics in Folsom, California for
laboratory analysis under modified EPA Method TO-15 Low Level. The list of analytes was
restricted to volatile organic compounds that have been detected in sub-slab soil vapor, indoor
air, or groundwater samples from the site during past investigation activities. The list includes
tetrachloroethene, trichloroethene, cis-1,2-dichloroethene, trans-1,2-dichloroethene, 1,1-
dichloroethene, 1,2-dichloroethane, vinyl chloride, chloroform, benzene, ethylbenzene,
naphthalene, m,p-xylene, and o-xylene. A level 2 QA/QC data package was requested for the
gas samples.
Terracon conducted the field work in accordance with a health and safety plan developed
specifically for this project. Work was performed using United States Environmental Protection
Agency (USEPA) Level D work attire consisting of hard hats, safety glasses, protective gloves,
and protective boots.
4.0 RESULTS
The laboratory analytical report and chain-of-custody records are attached in Appendix A. The
following sections describe the results of the testing.
4.1 Indoor and Outdoor Air Sample Results
Below is a summary of compounds detected in the August 2016 indoor/outdoor air samples above
the laboratory reporting limits:
§Benzene, ethylbenzene, tetrachloroethene, m,p-xylene, and o-xylene were detected in
each of the eight indoor and outdoor air samples collected in August 2016 (samples IA-02
through IA-06, DUP-01-08182016, OA-02, and OA-03).
§Chloroform and 1,2-dichloroethane were detected in outdoor air samples OA-02 and OA-
03.
§Naphthalene was detected in samples IA-02, IA-03, IA-04, and DUP-01-07132016.
§Trichloroethene was detected in sample OA-02.

Based on the narrative included in the laboratory analytical report, laboratory QA/QC procedures
indicate adequate laboratory method precision. The duplicate sample results are comparable to
the primary sample results, indicating satisfactory laboratory method precision. Air sample results
are summarized on Table 2. The laboratory analytical report is included in Appendix A.
Laboratory analytical results for the indoor and outdoor air samples were evaluated using the
NCDEQ IHSB Brownfields Indoor Air to Risk Calculators for a commercial exposure scenario,
version 3.45. Based on the calculator, none of the 5 indoor air samples collected at the site in
August 2016 exceed the acceptable cumulative risk or hazard quotient under a commercial
exposure scenario. The risk calculators are included as Appendix B of this report.
5.0 RE-EVALUATION OF FEBRUARY 2016 AIR SAMPLE RESULTS
The indoor and outdoor air samples collected at the site in February 2016 were originally
evaluated using the IHSB’s Indoor Air Screening Levels (IASLs). The Brownfields Program has
since transitioned to a risk-based approach and vapor intrusion/health risks are evaluated using
the Brownfields risk calculators as discussed in the previous section. Terracon re-evaluated the
February 2016 indoor and outdoor air results using the risk calculators at the request of the PD.
Based on this evaluation, none of the 5 indoor air samples collected at the site in February 2016
exceed the acceptable cumulative risk or hazard quotient under a commercial exposure scenario.
The February 2016 risk calculators are included as Appendix C of this report.
6.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the scope of services described in this report and subject to the limitations described
herein, Terracon provides the following conclusions.
§Laboratory analytical results suggest that several VOC constituents were present at low levels
in indoor and outdoor air at the site on August 18, 2016. Overall, duplicate and laboratory
QA/QC procedures suggest that the accuracy of the results is satisfactory.
§Since both the February 2016 and August 2016 indoor air samples collected at the site do not
exceed the acceptable risk and target hazard quotient thresholds, Terracon concludes that
further assessment, such as a third sampling event, is not required.

LABORATORY NARRATIVEModified TO-15 Full Scan/SIMTerracon Consulting EngineersWorkorder# 1608844
Eight 6 Liter Summa Canister (SIM Certified) samples were received on August 22, 2016. The
laboratory performed analysis via modified EPA Method TO-15 using GC/MS in the Full Scan and
SIM acquisition modes. The method involves concentrating up to 1.0 liters of air. The concentrated
aliquot is then flash vaporized and swept through a water management system to remove water vapor.
Following dehumidification, the sample passes directly into the GC/MS for analysis.
This workorder was independently validated prior to submittal using 'USEPA National Functional
Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based,
logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of
relevant project quality control requirements and verification of all quantified amounts.
Method modifications taken to run these samples are summarized in the table below. Specific project
requirements may over-ride the ATL modifications.
