CHARLOTTE, NORTH CAROLINA
NCBP No. 19040-15-060

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 within an industrial developed area (Mecklenburg County Tax
Parcel ID 08505412) in northeast Charlotte. The single-story industrial building at the site includes
a 7,546 square foot (sq. ft.) office area with an adjacent warehouse and manufacturing 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 include a supplier of steel bar stock and a
distributor of granite slabs for use as countertops. The site is currently within the North Carolina
Brownfields Program (NCBP) resulting from impacts by chlorinated compounds detected in the
groundwater on the property. The 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 located beneath the
warehouse floor slab. A topographic map showing the site location is included as Figure 1.
A No Further Action letter dated February 7, 2019 was issued by the NCDEQ UST Section for the
Intregis Metals release incident associated with on-site underground petroleum storage tanks.
On-site monitoring wells MW-1 through MW-5 and DW-1 and recovery well RW-1 were
abandoned on March 29, 2019 as part of the petroleum incident closure. Since well MW-5
(routinely sampled as part of the Brownfields requirements) had been installed as the up-gradient
well for the petroleum release and subsequently abandoned, Terracon installed a replacement
well (MW-5R) for abandoned well MW-5 on January 31, 2020. On-site monitoring wells (MW-6
through MW-10) associated with the assessment of chlorinated compounds from an off-site up-
gradient source were not abandoned. The source of chlorinated compounds is believed to be a
former diaper cleaning service located on the adjacent property to the north. The groundwater
flow direction at the site is towards the south-southeast. The locations of on-site monitoring wells
and other site features are shown on Figure 2. Water supply wells have not been reported within
1,500 feet of the site. The nearest surface water feature is an intermittent stream/drainage ditch
located approximately 500 feet to the southwest of the site. Based on local topography, water
from the drainage feature discharges into Little Sugar Creek.
According to Land Use Restriction 13 in the Brownfields Agreement, monitoring wells MW-5 (now
MW-5R) and MW-9 are required to be sampled each January for three consecutive years (starting

in 2018) or until the NCBP determines, in writing, that sampling is no longer required. The
Brownfields Agreement also states that the wells should be analyzed for volatile organic
compounds (VOCs) and semi-volatile organic compounds (SVOCs). Additionally, the NCBP
requires submittal of a Land Use Restrictions (LUR) Update form at the beginning of each year.
The LUR Update form was submitted to the NCBP in January 2020.
1.1 Occurrence of Chlorinated Volatile Organic Compounds (CVOCs) at the Site
Historically, groundwater samples obtained from on-site monitoring well MW-5 have shown the
highest concentrations of chlorinated compounds at the site at levels that exceeded the North
Carolina Administrative Code (NCAC) 2L Groundwater Standards. Well MW-5 was located within
the northwestern portion of the site, up-gradient of the on-site buildings and most operations
conducted on the property. Based on the VOC levels detected in well MW-5 and health and
safety concerns for personnel on the site and nearby properties, the Inactive Hazardous Sites
Branch (IHSB) opened Incident No. NONCD0001992 for the site in 2014. Based on preliminary
assessment activities conducted at the site, the IHSB recommended additional assessment to
identify the on-site source of the chlorinated VOCs (CVOCs).
In response to the recommendations of the IHSB, Terracon installed monitoring wells MW-9 and
MW-10 in August 2015 at locations up-gradient of well MW-5/MW-5R along the northwestern
property boundary to disprove IHSB’s claim of an on-site source. Analytical results from well MW-
9 detected the highest concentrations of CVOCs on the property. Well MW-9 is located directly
up-gradient of well MW-5/MW-5R at the northern property boundary. CVOCs were also detected
in wells MW-8 and MW-10 located in the northwestern portion of the site at concentrations several
orders of magnitude lower than wells MW-5 and MW-9.
A previously completed Phase I ESA conducted for the site in 2013 identified the adjacent Dy-
Dee Service, as an industrial laundry business formerly located on the property to the north and
up-gradient of the site. An approximate 1,500-gallon aboveground storage tank (AST) in poor
overall condition was reported as a Recognized Environmental Condition (REC) located at the
rear exterior of the Dy-Dee Service building. Terracon confirmed the presence of the AST in
August, October, and November 2015 and also observed several rusted 55-gallon drums stored
at the rear of the Dy-Dee Service building near the AST. Based on the groundwater flow direction
towards the south-southeast, a release from the AST, drums or former operations at the Dy-Dee
Service facility could potentially impact the groundwater quality at 527 Atando Avenue. A
secondary potential source for groundwater contamination is a former automotive repair shop that
was reportedly located in a building located at the rear of the Dy-Dee Service building (on the
same parcel). Terracon could not obtain information regarding the car repair business.

3.0 FIELD INVESTIGATION METHODS
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 a hard hat, safety vest, safety glasses, protective gloves, and protective boots.
3.1 Groundwater Sampling and Monitoring Well Installation
Groundwater Sampling (Well MW-9)
Terracon mobilized to the site on January 17, 2020 to collect groundwater samples from on-site
wells MW-5 and MW-9 as required by Land Use Restriction 13 within the Brownfields Agreement.
When Terracon personnel located well MW-5, it appeared that the well had been abandoned.
Terracon contacted Ms. Trudy Beverly with the NCDEQ UST Section to discuss the status of the
monitoring well. Ms. Beverly stated the wells associated with the UST release incident (Intregis
Metals) had been abandoned on March 29, 2019 including well MW-5.
Prior to sampling well MW-9 on January 17, 2020, the well was purged using a peristaltic pump
and low-flow techniques. Water quality parameters pH, specific conductance, oxidation-reduction
potential, dissolved oxygen, and temperature were measured in the well and recorded during
purging activities at five-minute intervals to ensure the groundwater had stabilized. Groundwater
sampling records are included in Appendix A of this report.
The groundwater samples from the well were placed in laboratory-supplied glassware, labeled
and stored in an ice-packed cooler. The samples, along with chain-of-custody documentation,
were delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for analysis of
VOCs by EPA Method 8260 and SVOCs by EPA Method 8270.
Monitoring Well Installation (Well MW-5R)
Terracon obtained approval for installing a replacement well for MW-5 (MW-5R) on January 29,
2020. Prior to intrusive activities, Terracon submitted a locate request to the public utility locator
[NC 811] to arrange for location of underground utilities from the street to the utility meter. As an
added measure of safety, Terracon subcontracted Probe Utility Locating to conduct private utility
locating services at the boring location. Terracon mobilized to the site on January 31, 2020 to
install groundwater monitoring well MW-5R in the vicinity of former well MW-5. Terracon
subcontracted Innovative Environmental Technologies (IET) Inc., a North Carolina licensed

drilling company to advance boring MW-5R utilizing hollow stem auger (HSA) drilling techniques
with an AMS Power Probe 9520 drill rig.
Permanent Type II monitoring well MW-5R was installed using the following procedures:
n Installation of 20 feet of two-inch diameter, 0.010-inch machine slotted Schedule 40 PVC
well screen with a threaded bottom cap from approximately 30 to 10 feet bgs;
n Installation of two-inch diameter, threaded, flush-joint PVC riser pipe from 10 feet bgs to
surface;
n Addition of pre-sieved 20/40 grade silica sand as a sand pack around the well screen from
the bottom of the boring to approximately two-feet above the top of the well screen;
n Addition of approximately five feet of hydrated bentonite chips on top of the sand pack;
n Grout remaining annulus above the bentonite seal to the land surface; and
n Installation of a flush-mounted protective cover sealed in a two-foot by two-foot concrete
pad.
The monitoring well construction details are summarized on Table 1. A copy of the field notes is
provided in Appendix A. Well construction records are provided in Appendix B.
Groundwater Sampling (MW-5R)
Prior to sampling well MW-5R on February 5, 2020, the well was purged using a peristaltic pump
and low-flow techniques. Water quality parameters pH, specific conductance, oxidation-reduction
potential, dissolved oxygen, and temperature were measured in the well and recorded during
purging activities at five-minute intervals to ensure the groundwater had stabilized. Groundwater
sampling records are included in Appendix A of this report.
The groundwater samples from the well were placed in laboratory-supplied glassware, labeled
and stored in an ice-packed cooler. The samples, along with chain-of-custody documentation,
were delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for analysis of
VOCs by EPA Method 8260 and SVOCs by EPA Method 8270.
3.2 Site Hydrogeology
Depth to groundwater was measured at 6.83 feet below top of casing (btoc) in well MW-5R and
5.85 feet btoc in well MW-9 (in 2015, depth to water levels were measured at approximately 12
to 13 feet btoc). The locations of the on-site wells are shown on Figure 2. Based on historical
measurements, groundwater in the shallow aquifer zone appears to be flowing towards the
south/southeast at the site. Groundwater depths and elevations are reported in Table 1.

4.0 ANALYTICAL RESULTS
According to the laboratory analytical reports, the following VOC and SVOC constituents were
detected during the January 17 (well MW-9) and February 5, 2020 (well MW-5R) groundwater
sampling events.
VOCs:
§Tetrachloroethylene (PCE) was detected in wells MW-5R (2,340 µg/L) and MW-9 (1,440
µg/L) at concentrations above its 2L standard of 0.7 µg/L.
§Trichloroethene (TCE) was detected in wells MW-5R (1,090 µg/L) and MW-9 (922 µg/L)
at levels above its 2L standard of 3 µg/L.
§cis-1,2-Dichloroethene (cis-1,2-DCE) was detected in well MW-5R (2,500 µg/L) and well
MW-9 (10,900 µg/L) above its 2L standard of 70 µg/L.
§Vinyl chloride was detected in well MW-5R (60.4 µg/L) above its 2L standard of 0.03 µg/L.
Vinyl chloride was not detected above the laboratory reporting limit in well MW-9.
§trans-1,2-Dichloroethene was detected in well MW-5R (12.9J µg/L) and well MW-9 (50.7J
µg/L) at estimated concentrations below its 2L standard of 100 µg/L.
§Benzene (44.4J µg/L), ethylbenzene (32.7 µg/L), toluene (123 µg/L) and total xylenes
(173.2J µg/L) were detected in well MW-9. The estimated concentration for benzene
exceeded its 2L standard.
SVOCs:
§SVOC constituents (fluoranthene and pentachlorophenol) were detected in well MW-5R
at estimated concentrations. Pentachlorophenol exceeded its 2L standard (0.3 µg/L).
Groundwater analytical results are also summarized in Table 2. The laboratory analytical reports
are provided in Appendix C.
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.
§Groundwater results indicate that CVOCs are present at concentrations exceeding the 2L
standards in monitoring wells MW-5R and MW-9. Total CVOC concentrations are
generally stable in wells MW-5R and MW-9 compared to previous sampling events (with
the exception of the sampling results for January 2019 when total CVOC concentrations
were significantly lower).
§The potential off-site CVOC source is believed to be located on the adjacent parcel to the
north of the site where the Dy-Dee Diaper business formerly operated and where several
rusted 55-gallon drums and ASTs were observed by Terracon and others. The off-site

source of the CVOCs is supported by high concentrations of CVOCs in the groundwater
along the northern property boundary.
§Historical groundwater flow direction at the site is towards the south/southeast.
§Natural attenuation of the CVOCs is apparent based on the presence of various daughter
products of tetrachloroethylene in the wells.
§BTEX constituents were detected in well MW-9 during this sampling event.
Based on the findings of our assessment activities, the following comments and recommendations
are provided for the site.
§Terracon recommends sampling wells MW-5R and MW-9 in January 2021 in accordance
with Land Use Restriction 13 in the Brownfields Agreement and the attached email from
Ms. Carolyn Minnich of NCDEQ dated March 13, 2020 included in Appendix D.

Subject:RE: [External] Atando Brownfields Site
Flora: Thank you for following up with us. DEQ must approve the request to cease sampling. The requirement does not
just expire. I would recommend the property owner budget additional funds for future years for groundwater
sampling. Based on the requests to date, the sampling should continue.
LUR 13 states the following:
m. Beginning in the first January following the year in which the Notice of Brownfields Property
referenced below in paragraph 20 is recorded, and every January after that unless and until DEQ determines in writing,
after a minimum of three(3) sampling events, that protection of public health and the environment no longer requires
such sampling, the owner(s) of the Brownfields Property shall effect sampling of monitoring wells MW-5 and MW-9 in
accordance with the most current version of the Guidelines of the Inactive Hazardous Sites Branch of DEQ's Superfund
Section. The groundwater samples collected during such activities shall be analyzed for volatile and semi-volatile
organic compounds by Method 8260 and Method 8270 of the U.S. Environmental Protection Agency or any comparable
method approved in advance by DEQ. A Groundwater Monitoring Report setting forth the procedures and results of
these groundwater sampling activities shall be submitted with the Land Use Restrictions Update referenced below in
subparagraph 15.o.v in those years during which groundwater sampling is required.
LUR 15 states:
o. During January of each year after the year in which the Notice referenced below in paragraph 21 is recorded, the
owner of any part of the Brownfields Property as of January 1st of that year shall submit a notarized Land Use
Restrictions Update (“LURU”) to DEQ, and to the chief public health and environmental officials of Mecklenburg County,
certifying that, as of said January 1st, the Notice of Brownfields Property containing these land use restrictions remains
recorded at the Mecklenburg County Register of Deeds office and that the land use restrictions are being complied with.
The submitted LURU shall state the following:
2
v. the laboratory analytical results acquired from annual sampling in monitoring well MW-5 and
MW-9 referenced in subparagraph 15.m above for a minimum of three years following execution of this Agreement,
and/or until DEQ otherwise approved.

Carolyn,
The Land Use Restriction 13 in the Brownfields Agreement requires three annual sampling events and the 2020 sampling
event was the third. As you can see on the attached table, the concentrations increased. Because of the increase in
concentrations, will you/Brownfields require additional sampling or will the 2020 event be the final event?
Thank you,
Flora J. D’Souza, CHMM
