War Memorial Stadium - New Scoreboard
Brownfield Project ID 20043-16-41
Greensboro, North Carolina
S&ME Project No. 4358-17-032
Dear Ms. Irick:
S&ME, Inc. (S&ME) is pleased to submit soil sampling results for the proposed baseball scoreboard project at the
War Memorial Stadium located at 420 West Yanceyville Road, Greensboro, North Carolina. Our services were
performed in general accordance with the Sampling Plan prepared by S&ME and dated January 12, 2018.
Project Background
The North Carolina Department of Environmental Quality, Brownfields Program (NCDEQ) lists the War Memorial
Stadium property as an Active Eligible Brownfield Project with ID # 20043-16-41. At this time the NC A&T State
University's redevelopment plan details are conceptual and a Brownfields Agreement (BFA) has not been finalized.
In 2016, an Environmental Management Plan was developed for the War Memorial Stadium project based on the
conceptual plans for redevelopment.
Currently, a new scoreboard is planned to be constructed south of and adjacent to the light tower beyond left
field of War Memorial Stadium (Figure 1). The scoreboard has dimensions of 16 by 25 feet and will be supported
on two columns spaced 15 feet apart. The columns will either be supported with individual drilled shafts or a
single mat foundation. Based on preliminary conversations between Ms. Hayley Irick with NCDEQ and Edmund
Henriques of S&ME, we understood that a limited Sampling Plan was needed for the proposed scoreboard
project. A Sampling Plan date December 21, 2017, was submitted to NCDEQ. In an email to Edmund Henriques
of S&ME dated January 12, 2018, Ms. Hayley Irick provided limited comments on the original Sampling Plan. The
Sampling Plan, Revision 1 incorporated changes to address comments provided by the NCDEQ.
Soil Assessment
On January 25, 2018, an S&ME environmental professional was on site during performance of the
geotechnical soil borings. Two soil borings, identified as B-1 and B-2, were drilled with hollow -stem
augers to approximate depths of 20 feet below ground surface and at the locations shown on Figure 2.
Split -spoon samples of subsurface soils were taken at approximate 2.5-foot intervals above a depth of 10

feet and at 5-foot intervals below 10 feet. Boring Logs describing observed subsurface conditions are
attached.
S&ME observed soil cuttings for potential indications of chemical impacts. No chemical odors or staining
was observed in the soil cuttings or soil samples. A copy of the Environmental Field Report is attached.
S&ME collected soil samples from each split -spoon sampling interval for field screening of volatile organic
vapors and for laboratory analyses.
Each soil sample was placed into sealable plastic bags and allowed to equilibrate to ambient conditions.
The headspace of each bag sample was field screened using a photoionization detector (PID). Field
screening did not detect any measurable concentration of volatile organic vapors in each sample.
Based on the observation of apparent saturated conditions approximately four feet below ground surface
in soil boring B-2, S&ME prepared the soil sample collected from 1.0 feet to 2.5 feet below ground surface
in each soil boring for laboratory analysis. The collected grab soil samples were transferred into
laboratory -provided containers. The sample containers were labeled and placed into a cooler with ice and
delivered to the analytical laboratory under proper chain of custody.
The soil samples were submitted for analysis by a North Carolina certified laboratory, for volatile organic
compounds (VOCs) by Method 8260, semi -volatile compounds (SVOCs) by Method 8270, and the 13
Priority Pollutant Metals by EPA Method 6010 and EPA Method 7471 (as total metals).
Boreholes were observed for groundwater at completion of drilling. Groundwater was encountered in
borings B-1 and B-2 at approximate depths of 8 feet and 5 feet below ground surface, respectively, two
hours after the performance of the borings. Following collection of depth to water readings, the
boreholes were backfilled with bentonite hole plug to the water level and then auger cuttings. Excess
auger cuttings were stored in a 55-gallon metal drums and stored on -site pending disposal.
Soil Analytical Results
Analytical results were reviewed relative to the NCDEQ Inactive Hazardous Sites Branch, Preliminary Site Remedial
Goals (PSRG), updated October 2017. The following provides a brief summary of the analytical results for each
soil sample. Table 1 provides a summary of the soil sample analytical results. A copy of the laboratory analytical
report is attached.
Soil Sample: B-1-2.5
Beryllium, Chromium, Lead, Nickel, Selenium, Zinc and Mercury were detected at concentrations greater
than the reporting limit, but less than the lowest corresponding IHSB PSRGs.
Target analytes were not detected by EPA Method 8260 or by EPA Method 8270.
Soil Sample: B-2-2.5
Beryllium, Chromium, Lead, Nickel, Zinc and Mercury were detected at concentrations greater than the
reporting limit, but less than the lowest corresponding IHSB PSRGs.
Selenium was reported at a concentration greater than the corresponding IHSB Protection of
Groundwater PSRG but less than the IHSB Residential Health PSRG and the IHSB Industrial/Commercial
PSRG.
Anthracene, Benzo(k)fluoranthene, Chrysene, Fluoranthene, and Pyrene were detected at concentrations
greater than the reporting limit, but less than the lowest corresponding IHSB PSRGs.

Soil Sampling Results
Brownfield Project ID 20043-16-41
Greensboro, North Carolina
S&ME Project No. 4358-17-032
Benzo(g,h,i)perylene and Phenanthrene were detected at concentrations greater than the reporting limit,
but no PRSGs are provided.
Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Dibenz(a,h)anthracene and Indeno(1,2,3-
cd)pyrene were detected at concentrations greater than the IHSB Residential Health PSRG and the IHSB
Protection of Groundwater PRSG, but less than the IHSB Industrial/Commercial PSRG.
Target analytes were not detected by EPA Method 8260.
Analytical results for the soil sample obtained above groundwater at boring B-2, detected multiple SVOCs that are
consistent with SVOCs historically detected in soil and groundwater near the main entrance to the stadium. By
comparison, no SVOCs were detected in the soil from boring B-1, at a similar depth. Based on the analytes and
concentrations detected at boring B-2, installation of foundations for the scoreboard will require proper
management and disposal of excavated soil. If foundation(s) are to extend below the water table, proper
management of groundwater would be appropriate.
In accordance with 29 CFR 1910.120 hazardous waste operations and emergency response (HAZWOPER) rule for
the protection of workers, we anticipated that construction workers which may come in contact with soil
excavated for construction of the foundations would likely require HAZWOPER training and development of a
site -specific health and safety plan (HASP).
We recommend off -site disposal of the excess soil cuttings drummed and currently stored on site.
Closure
Please contact the undersigned should you have any questions regarding the soil sampling results.

❑ Driller- John Wingo, two crew members
7:30- Pack equipment, prepare Health & Safety plan, load water for crew decon
8:00- Mobilization
8:28- Arrive on -site, meet Shaban Kazi, crew arrive 8:30. Reviewed boring location off -sets 5 feet from flags on marked
underground power line (towards the fence). Told Mr. Kazi that we will leave one soil drum on -site.
Completed Tailgate Safety meeting with drill crew.
8:45- Set-up rig on soil boring B-2. Drilled with 3-1/4-inch hollow -stem augers, sampled with split -spoon sampler. Augers
were steamed -cleaned prior to arrival, spoons were washed by hand with alconox solution.
John Wingo collected samples in geotech jars and LButler collected samples in ziplock bags. Wingo and Butler recorded soil
characterization and SPT values on forms. Samples were collected at 1.0-2.5 feet, 3.5-5 ft, 6-7.5 ft, 8.5-10 ft, 13.5-15 ft and
18.5-20 ft. TOB = 20 ft. No chemical odors or staining was observed in collected soil samples. After allowing for equilibration,
Butler screened headspace of bag samples for volatile organic vapors with photo -ionization detector. Each sample was non -
detect. Butler reported preliminary results by phone to S. Lacz, and discussed shallow groundwater (approx. 4 ft) with E.
Henriques.
9:40- Set-up on soil boring B-1. Collected and screened soil samples with same procedures as B-2.
10:40- DTW in boring B-2 approximately 6 ft below ground. Wingo left site to pick-up bentonite (to backfill borings to top of
water). LButler prepared soil samples for analysis in laboratory -prepared containers for 8260B, 8270D, and Metals. Containers
were labeled, chain -of -custody form was initiated and samples were stored in a chilled cooler. At 10:55, cave-in was 13 feet
and approx. DTW was 6 feet in B-2, and cave-in was 16 ft and approx. 10 ft in B-1.
11:40- Wingo returned. DTW was remeasured, 5 ft bgs in B-2 and 8 ft in B-1. Wingo backfilled boring with bentonite chips to
top of water, then backfilled to ground surface with soil cuttings. Excess soil cuttings from both borings was placed in 55-
gallon metal drum, and drum was staged beside adjacent light pole. Date, location, and "Soil-Non-Haz" was marked with
sharpie on drum lid. Wingo provided soil jars and log form.
12:00 Demobe,
12:30- return to office. Provided soil samples and boring forms to Ariful Bhuiyan. Unloaded equipment, completed field
report. Butler called Pace Lab to arrange for sample pick-up on 1/26/18.
