ATANDO AVENUE BROWNFIELDS SITE
527 ATANDO AVENUE
CHARLOTTE, NORTH CAROLINA
Terracon Project No. 71157718
March 22, 2016
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 approximately 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 within 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 IASL.
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 investigation discussed in this report was
designed to meet the requirements for the first of these additional 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 (Appendix A)
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-01-02242016 – a duplicate indoor air sample collected at IA-06 for QA/QC purposes.
§OA-02 (outdoor air) near the fence along the eastern site boundary to evaluate
background air concentrations
2.2 Standard of Care

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 (Appendix A) by interviewing Mr. Charles Morgan with Sunbelt-Turret (the
tenant) on February 24, 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. Morgan a summary sheet with information on indoor/outdoor air
sampling for the on-site workers. A copy of the summary sheet is included in Appendix A.
Sample locations are shown on Figure 2.
Air sampling was conducted on February 24, 2016 in general agreement with the DWM Vapor
Intrusion Guidance. Five indoor air samples and one outdoor air sample 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 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 sample was collected at the eastern site boundary towards Atando
Avenue. This was considered upwind of the on-site building on the day of sample collection.
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 7 sample canisters (including one blind duplicate
sample collected at location IA-06 in addition to the primary sample for QA/QC purposes) on an
approximate hourly basis. The indoor and outdoor air sample collection records are provided in
Appendix A of this report. A sampling and analysis plan is provided as Table 1.
Following completion of the field activities, the Summa canisters (7 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
tetrachloroethylene, trichloroethylene, cis-1,2-dichloroethene, trans-1,2-dichloroethene, 1,1-
dichloroethene, 1,2-dichloroethane, vinyl chloride, chloroform, benzene, ethylbenzene, p-
isopropyltoluene (p-cymene), 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 under a health and safety plan developed 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 B. The
following sections describe the results of the testing.
4.1 Indoor and Outdoor Air Sample Results
Laboratory analytical results for the indoor and outdoor air samples were compared to the NCDEQ
Indoor Air and Crawlspace Screening Concentrations (IASL) for residential and non-residential
exposure scenarios, updated September 2015. The values assuming a target carcinogenic risk
of 1.0E-06 and a target hazard quotient of 0.2 (i.e., the IASL(A) values on the screening tables)
were used for this assessment. Below is a summary of laboratory analytical results:
§Benzene was detected at concentrations exceeding its Residential IASL in sample IA-02
(0.37 µg/m3), as well as samples IA-06 and DUP-01-02242016 (0.39 and 0.55 µg/m3,
respectively). Benzene was also detected in the remaining three indoor air samples IA-
03, IA-04, and IA-05 at concentrations below the Residential IASL. Background air sample
OA-02 contained benzene at a concentration slightly below the Residential IASL.
Limited Site Investigation

March 22, 2016 ■ Terracon Project No. 71157718
Responsive ■Resourceful ■Reliable 5
§Chloroform was detected in DUP-01-02242016 (0.20 µg/m3) above its Residential IASL of
0.122 µg/m3. Chloroform was not detected in the other air samples obtained from the site.
§Naphthalene was detected above its Non-Residential IASL in sample IA-02 (0.63 µg/m3)
and in outdoor air sample OA-02 (0.55 µg/m3). The compound was not detected in the
other air samples obtained from the site.
§Tetrachloroethene was detected above the Residential IASL in background air sample
OA-02 (20 µg/m3). Tetrachloroethene was also detected within indoor air samples IA-06
and DUP-01-02242016 at concentrations below the Residential IASL. Tetrachloroethene
was not detected in the other air samples obtained from the site.
§In addition to the compounds listed above, the following constituents were detected in at
least one sample below IASLs:
o Ethylbenzene (IA-02, IA-03, IA-06, DUP-01-02242016, and OA-02)
o m,p-Xylenes (IA-02 through IA-06, DUP-01-02242016, and OA-02)
o o-Xylene (IA-02, IA-03, IA-06, DUP-01-02242016, and OA-02)
Based on the narrative included in the laboratory analytical report, there were no laboratory
internal QA/QC discrepancies associated with these samples. The duplicate sample results are
comparable to the primary sample results, with the exception of tetrachloroethene which was
detected at a concentration one order of magnitude higher in the duplicate sample compared to
the primary sample. Air sample results are shown on Figure 3 and summarized on Table 2. The
laboratory analytical report is included in Appendix B.
5.0 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.
§The two samples from the production warehouse area (IA-04 and IA-05) did not contain any
target constituents above the IASLs. The production warehouse has a thick reinforced
concrete slab and several large bay doors that are open most of the day which may inhibit
accumulation of soil vapor in this portion of the building. Based on these results, vapor
mitigation is not required in the production warehouse.
§The primary and QA/QC samples (IA-06 and DUP-01-02242016) collected in the southern
warehouse near well MW-1 contained various petroleum and chlorinated compounds at levels
below non-residential IASLs. The warehouse area is currently unoccupied but is occasionally
used for storage. Based on the indoor air concentrations and current use, no vapor mitigation
is required at the southern warehouse area at this time.
§February 2016 analytical results for the office area (IA-02) are comparable to November 2015
results from the safe/break room area (IA-01). Naphthalene was detected above the non-
residential IASL in both samples. Naphthalene was also detected in background/outdoor air
sample OA-02 (February 2016) above the non-residential IASL at a concentration similar to
Limited Site Investigation

sample IA-02. While a non-residential IASL exceedance would generally indicate the need for
vapor mitigation measures in the office area, the presence of naphthalene detected in the
outdoor air sample at a similar concentration suggests per DWM Vapor Intrusion Guidance
that vapor mitigation will not be required by the NC Brownfields Program at this time. Terracon
recommends collection of two outdoor air samples during the next sampling event (Summer
2016) for comparison purposes. One of the outdoor air samples would be located near sample
OA-02 while the second sample would be collected along the western side of the building.

You will be asked a series of questions about the structure, consumer
products you store in your building, and household activities typically
occurring in the building. These questions are designed to identify
“background” sources of indoor air contamination. While this investigation is
looking for a select number of chemicals related to the subsurface
contamination, the laboratory may be analyzing the indoor air samples for a
wide variety of chemicals. Thus, tetrachloroethene used in dry cleaning or
acetone found in nail polish remover might be found in your sample results.
Your cooperation is greatly appreciated.
If you have any questions about these instructions, please feel free to contact:

LABORATORY NARRATIVEModified TO-15 Full Scan/SIMTerracon Consulting EngineersWorkorder# 1603093
Seven 6 Liter Summa Canister (SIM Certified) samples were received on March 02, 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.

Receiving Notes
There were no receiving discrepancies.
The results for each sample in this report were acquired from two separate data files originating from the
same analytical run. The two data files have the same base file name and are differentiated with a "sim"
extension on the SIM data file.
