This memorandum summarizes the February 2019 installation and sampling of monitoring well (MW-
1R) and soil vapor points (VP-1 to VP-10) at the Forest City Brownfield Project Site (the Site). The Town
of Forest City has received a Certificate of Occupancy for the newly constructed Amphitheatre dated
April 3rd, 2019, as presented in Attachment A.
Report Objectives:
• Summarize the February 2019 environmental monitoring point installation and sampling.
• Present analytical results for groundwater and vapor samples, as well as soil from the
Investigative Derived Waste (IDW) for waste characterization. Analyses for IDW included volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and RCRA
metals, including arsenic, barium, cadmium, chromium (speciated), mercury, lead, selenium, and silver. Groundwater and vapor sample analyses was for VOCs only.
• Document completion of the construction of the Amphitheater.
Monitoring Point Installation
AECOM arrived at the project site on February 11, 2019, to complete work originally proposed in the
Environmental Management Plan (EMP) by Irminger Consulting Inc. (IC), dated December 2, 2013. The
field work objective was to re-install and sample monitoring well (MW-1R), install and sample five nested
permanent Soil Gas Vapor Points (VP-1 to VP-10), and sample pre-existing monitoring well (MW-17).
These represent repeatable sampling points to form the basis of annual monitoring at the Site. South
Atlantic Environmental Drilling and Construction Company (SAEDACCO), a North Carolina Certified
Drilling subcontractor performed the monitoring well and soil vapor point installation under the direction
of an AECOM geologist, and in accordance with North Carolina Well Construction Standards.
Subsurface utility clearance was initiated before drilling started. Locations of the newly installed
monitoring points and pre-existing MW-17 are located on Figure 2. The new monitoring locations are
also presented with the Amphitheatre design on Figure 3. A photo log of the described fieldwork is
presented in Attachment B.

Monitoring well MW-1R was installed to a depth of 39 feet below ground surface (bgs), with Hollow Stem
Auger (HSA), and constructed of schedule 40, 2-inch diameter poly vinyl chloride (PVC) casing and
screen. A 15-foot-long section of 0.010-inch machine slotted well screen was placed at the bottom of
monitoring well. Annular space between the well screen and the borehole was packed with a number
two fine filter sand from the termination depth to approximately two feet above the screened interval. A
minimum of 2-foot thick bentonite seal was placed above the sand pack with the remaining annular
space grouted to the surface with a Portland cement/bentonite slurry. After installation, MW-1R was
developed. Development activities included removal of suspended solids and allowed to recharge a
minimum of 24 hours prior to sampling.
Nested soil vapor points were also installed with HSA. One foot long stainless-steel vapor implants with
0.0057-inch screen were placed at 19-20 feet bgs, and also at 4.5-5.5 feet bgs in each of the five nested
soil vapor monitoring points. Lithology was logged and field screening was conducted by use of a
photoionization detector (PID), calibrated to the manufacturer’s specifications. Detailed description of
the lithology encountered and monitoring well/soil vapor construction logs installed as part of this work
scope are included in Attachment C.
Monitoring Well Sampling Methods
Prior to sampling, monitoring wells were purged using a monsoon pump based on the depths of the
water column and well depth. During purging of the monitoring wells, the field water quality indicator
parameters of temperature, pH, specific conductance, dissolved oxygen, and oxidation-reduction
potential (ORP) were measured using a YSI 556 portable field instrument equipped with a flow through
cell. Groundwater samples were collected when the field parameters stabilized to within 10 percent for
three consecutive readings. Samples were collected in pre-preserved, laboratory provided containers
and were immediately placed on ice. The groundwater sample collection sheets with field-measured
water quality data are included as Attachment D. The laboratory analytical reports for the groundwater
samples are presented in Attachment E.
Groundwater samples were placed on ice and transported to Pace Analytical in Nashville, Tennessee
under chain of custody for analysis of VOCs by USEPA Method 8260B.
Soil Vapor Sampling Methods
Soil gas samples were collected from the newly installed soil vapor monitoring points using 6-liter
Summa canisters fitted with 0.5-hour flow controllers. Helium tracer gas was used before sampling the
soil gas monitoring points to verify if any air leaks were present within the bentonite seal. Samples were
submitted to a certified laboratory for analysis of volatile organic compounds (VOCs) by United States
Environmental Protection Agency (EPA) Method TO-15-full analyte list. The laboratory analytical reports
for the soil vapor monitoring points are presented in Attachment E.
Investigative Derived Waste (IDW)
Investigative derived waste (IDW), including soil cuttings and groundwater generated from assessment
activities, and purge water generated during monitoring well development and groundwater sampling
were containerized in 55-gallon drums and stored onsite until proper waste disposal was arranged. One
Page 3 of 4
IDW soil sample with composited drill cuttings was placed on ice and transported to Pace Analytical in
Nashville, Tennessee under chain of custody for analysis of Target Compound List (TCL) VOCs via
Method 8260B, TCL SVOCs via Method 8267D, and RCRA metals via Method 6010D/7471B.
Groundwater Analytical Results
A summary of groundwater analytical results for the February 14, 2019 sampling, can be found in
Table 1.
• 12 total compounds were detected in MW-1R. Five compounds were detected over their respected NC 2L Standard in MW-1R (Benzene, Naphthalene, tetrachloroethylene (PCE),
trichloroethylene (TCE), 1,2,3-Trimethylbenzene). Two compounds were detected in MW-17,
but only one compound exceeded the NC 2L Standard (PCE).
• PCE was delectated above the respected NC 2L Standard of 0.7 micrograms per liter (µg/L) in
samples MW-1R and MW-17. Detected concentrations of PCE were 2830 µg/L in MW-1R, and 200 µg/L in MW-17.

Soil Gas Analytical Results
A summary of soil gas analytical results for the February 13-14, 2019 sampling, can be found in
Table 2. The following VOCs were detected above their corresponding NC DEQ Non-Residential Vapor
Intrusion Screen levels.
• A combined total of 33 compounds were detected in soil gas points VP-1 to VP-10. Only two compounds (PCE, TCE) were detected over the NC DEQ Non-Residential Vapor Intrusion
Screening Level.
• PCE was detected over the NC DEQ Non-Residential Vapor Intrusion Screening Level of 3,500
µg/m³ in VP-1, VP-2, VP-3, and VP-4. PCE values ranged from 7,000 µg/m³ in VP-1, to
12,000,000 µg/m³ in VP-4.
• TCE was detected at 4,100 µg/m³ in VP-4, exceeding the respected NC DEQ Non-Residential
Vapor Intrusion Screening Levels of 180 µg/m³.

Investigative Derived Waste (IDW) Results
A summary of the IDW soil analytical results for the February 2019 sampling can be found in Table 3.
• Benzene was detected in sample (IDW-SOIL), but was below the TCLP Regulatory limits of 100 µg/L.
• Separate IDW samples for groundwater were not submitted. Results of groundwater sample
MW-1R were used for IDW characterization of the containerized water from sampling and well
development. The results of MW-1R characterized the waste as a Hazardous Waste Liquid because of elevated levels of PCE.
Three 55-gallon drums of IDW-soil and one drum of IDW-water was properly disposed on April 17,
2019. Signed waste manifest for the IDW is presented in Attachment F.

Construction Complete
On April 3, 2019 the certificate of occupancy was finally received for the Amphitheater project
(Attachment A). It has been constructed consistent with the design plans and the August 2017
Environmental Management Plan. The location of the former drycleaner is capped under concrete, and
a Geo-Seal® Vapor-Vent™ system was installed to mitigate vapors in the snack bar / restroom building,
as documented in the Vapor Barrier System Memorandum, dated November 29, 2018.
Per the Brownfield agreement, monitoring will continue annually, on or about February 13th each year. If
concentrations for all exceeding parameters decrease over a period of three consecutive years, the
Town of Forest City may request that monitoring for that media (groundwater or soil vapor), to be
eliminated.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.
