On behalf of The Charlotte Observer, Amec Foster Wheeler Environment & Infrastructure, Inc.
(Amec Foster Wheeler) is pleased to submit this Aggressive Fluid/Vapor Recovery (AFVR) and
Groundwater Monitoring Report for the referenced property located at 621 South Poplar Street in
Charlotte, North Carolina (Figure 1).
SITE BACKGROUND INFORMATION
The subject site is located at the southwest corner of the intersection of West Stonewall and South
Poplar streets and is known as the Charlotte Observer warehouse facility. In early June 1989, a
release of approximately 1,500 gallons of unleaded gasoline occurred at the site. The release
apparently was the result of a product line break in the vicinity of a submerged turbine pump on
one of the two 12,000-gallon underground storage tanks (USTs) formerly located at the site
(Figure 2). The leak was reportedly repaired by Southern Pump and Tank Company (SPATCO).
Soil and ground -water assessments were performed by SPATCO between 1989 and 1991 and
included drilling four soil borings and installing nine groundwater monitoring wells (MW-1 through
MW-9). The report summarizing the activities was submitted to the Charlotte Observer and
forwarded to the North Carolina Department of Natural Resources (NCDENR).

Charlotte Observer — AFVR and Groundwater Monitoring Report November 9, 2016
621 South Poplar Street, Charlotte, North Carolina
Amec Foster Wheeler Project: 6228-12-0063
Results of the assessment activities indicated that gasoline -affected groundwater was migrating
away from the former UST tank area toward the north (toward former location of well MW-4). Due
to the presence of free -phase product in well MW-3 (nearest to former USTs), a product -recovery
well (RW-1) and system were installed in May 1990. The system was shut down in November
1990 due to product thickness reduction.
In November 1997, Amec Foster Wheeler (as LAW) was retained to assist in the closing of the
USTs. LAW submitted the closure report to the NCDENR in January 1998. In addition to the UST
closure services, LAW provided additional environmental services at the site, including: 1) the
sampling of monitoring well MW-3 in November 1997; 2) the abandonment of monitoring wells
MW-2, MW-5, MW-6, MW-8 and RW-1 in August 1998 prior to the commencement of construction
excavation activities; and 3) observation/sampling of soils removed from the excavation in and
around the UST area in September 1998 as part of construction activities. LAW presented the
results of these activities to the NCDENR in our Soil Clean -Up Report dated December 15, 1998.
It is our understanding that the remaining site wells were abandoned by The Charlotte Observer
prior to the planned construction activities.
Based on review of LAW's Report, NCDENR issued a letter (dated January 11, 1999) to the
Charlotte Observer requiring re -sampling of well MW-7 (or groundwater at the same depth in the
area of MW-7) and the installation of a "source area" monitoring well where the USTs were formerly
located. This letter further required analysis of the water samples by EPA Methods 601 and 602
(extended to include MTBE and IPE). Charlotte Observer personnel decided to postpone the work
at that time.
NCDENR issued a Notice of Regulatory Requirements (NORR) letter, dated May 4, 2012. In the
letter, NCDENR requested the installation of two monitoring wells, sampling and analysis of the
groundwater and preparation of a report. In June 2012, Amec Foster Wheeler installed the wells
(MW-3A and MW-4A). Free product was identified in well MW-4A in June 2012. Amec Foster
Wheeler's Groundwater Monitoring Report (dated July 13, 2012) was provided to NCDENR. Upon
review of the report, NCDENR requested that free product recovery efforts begin and additional
wells be installed to assess the extent of free product. On September 22, 2012, Amec Foster
Wheeler personnel mobilized to the site along with Geologic Exploration (Geologic) to install the
three new Type II monitoring wells (MW-10, MW-11 and MW-12) as requested by NCDENR.

In 2013, 2014, 2015, and 2016, Amec Foster Wheeler's efforts have been focused on removal of
free product from well MW-4A. In January 2016, Amec Foster Wheeler performed groundwater
monitoring of the site wells and submitted a Groundwater Monitoring Report to the North Carolina
Department of Environmental Quality (NCDEQ, formerly NCDENR). Based upon continued high
concentrations of dissolved petroleum constituents in well MW-4A identified in the April 2016
groundwater sampling event, NCDEQ requested an AFVR event to be scheduled in October 2016
followed by a groundwater sampling event.
AGGRESSIVE FLUID VAPOR RECOVERY (AFVR) ACTIVITIES
Amec Foster Wheeler arranged for an AFVR event to be performed at the site on October 17, 2016.
The purpose of the AFVR event was to remove petroleum -affected groundwater and free -phase
hydrocarbons (if present) under high vacuum pressures from monitoring well MW-11. The AFVR
also simultaneously treated affected soils within the smear zone, as the high vacuum pressures
lowered the water table in the immediate vicinity of well MW-11 exposing smear zone soils. The
AFVR event was run for approximately eight consecutive hours on October 17, 2016.
A&D Environmental Services, Inc. (Amec Foster Wheeler's subcontractor) performed the AFVR
event in well MW-11, as directed by NCDEQ. The depth to groundwater and depth to free product
(if applicable) was measured in wells MW-4A and MW-11 prior to the event using an oil/water
interface probe. The well locations are shown on Figure 2. The water level/product level
measurements (Table 1) did not detect measurable thickness of free product in the wells checked.
The fluid levels measurements did not suggest water table "drawdown" in wells other than MW-
11.
Several measurements were collected during the event. The measurements were collect at 15-
minute intervals from 8:45 am to 9:30 am and at 30-minute intervals thereafter until 4:30 pm. Air
velocity measurements, temperature and relative humidity measurements were taken by Amec
Foster Wheeler personnel from the stack using a Testo Model 400/445 meter. Total petroleum
hydrocarbons (TPH) concentration measurements in parts per million were taken using a MiniRae
2000-10.6 eV PID. The measurements collected during the event and emission calculations are
shown in Attachment A.

A total of 442 gallons of product/water mixture were removed from well MW-11 during the event
and disposed at a permitted North Carolina facility (see liquid manifest in Attachment A).
GROUNDWATER SAMPLING AND ANALYSIS
Due to the scheduled construction activities for the subject property, groundwater samples were
collected from wells MW-4A and MW-11 one week following completion of the AFVR event. On
October 24, 2016, Amec Foster personnel visited the subject property to collect groundwater
samples from wells MW-4A and MW-11. Prior to sampling, the water level was measured in wells
MW-3A, MW-4A, MW-10, MW-11 and MW-12 with an electric water level indicator to determine
depth to the water surface from the top of PVC riser pipe. Additionally, each well was checked for
the presence of free product was measured using a disposable bailer. Amec Foster Wheeler
personnel did not identify measureable thicknesses of free -phase petroleum product in monitoring
wells MW-3A, MW-4A, MW-10, MW-11 and MW-12 (Table 1). A sheen was noted on the water
collected from well MW-4A. Amec Foster Wheeler personnel purged well MW-4A of five casing
volumes and well MW-11 of four casing volumes of groundwater. After purging was complete,
groundwater samples were collected from the two wells using disposable polyethylene bailers. The
groundwater samples collected on October 24, 2016 were placed in laboratory -provided containers
with appropriate preservatives, placed in an ice -filled sample cooler and delivered to Pace Analytical
Services, Inc. (Pace) in Huntersville, North Carolina for analysis of Volatile Organic Compounds
(VOCs) by EPA Method 6200B. The samples were maintained under chain -of -custody protocol.
GROUNDWATER MOVEMENT
Groundwater movement is often related to topography, lithology, elevation or recharge and
discharge areas, and man-made influences. In October 2012, Amec Foster Wheeler personnel
measured the top of casing elevations of the wells at the site for the purpose of assessing
groundwater flow direction.
The top of casing elevations were measured relative to a reference point located near well MW-4A.
An assumed elevation of 731.00 feet above mean sea level was assigned to the point. Based on the
USGS topographic map, the elevation assigned to the reference point is probably within
approximately 1 or 2 feet of the actual elevation. The top of casing elevations were measured relative
to a reference point located near well MW-4A. On October 24, 2016, Amec Foster Wheeler personnel

measured stabilized water level in each well with an electronic water level indicator. These
measurements and the calculated groundwater elevations are presented in Table 1.
GROUNDWATER MONITORING WELL ABANDONMENT
On October 27, 2016, Amec Foster Wheeler and its well abandonment subcontractor (Innovative
Environmental Technologies, Inc. [IET]) mobilized to the subject property to abandon the remaining
groundwater monitoring wells at the subject property (MW-3A, MW-4A, MW-10, MW-11 and MW-
12). The monitoring well screen and casings were filled with a cement mixture to the ground surface
by IET, a driller licensed in North Carolina. The Mecklenburg County Subsurface Investigation Permit
(SIP) and the monitoring well abandonment records are included as Attachment B.
GROUNDWATER ANALTYCAL RESULTS
The laboratory analytical report is presented as Attachment C and the historical and current data
are summarized on Table 2.
None of the contaminant concentrations exceeded the Gross Contaminant Levels
(GCLs).
Benzene was identified in the groundwater in wells MW-4A (3,180 pg/L) and MW-
11 (3,570 pg/L) at concentrations that exceeded the North Carolina 2L (NC 2L)
Groundwater Standard for benzene (1.0 pg/L).
Ethylbenzene, toluene, xylenes, diisopropyl ether (IPE), isopropyl benzene, 1,2,4-
Trimethyl benzene, 1,3,5-Trimethyl benzene, methyl-tert-butyl ether (MTBE), n-
Propylbenzene and naphthalene were identified in the groundwater sample from
well MW-4A at concentrations that exceeded their respective NC 2L Groundwater
Standards.
Ethylbenzene, xylenes, IPE, MTBE, n-Propylbenzene, 1,2,4-Trimethyl benzene, and
naphthalene were identified in the groundwater sample from well MW-11 at
concentrations that exceeded their respective NC 2L Groundwater Standards.
VPH Aliphatics (C05-CO8) and Aliphatics (C09-C12) were not included in analysis
for the October 2016 sampling event.

CONCLUSIONS AND RECOMMENDATIONS
Based on the observations and results from the groundwater monitoring conducted at the subject
property, Amec Foster Wheeler offers the following conclusions:
Measurable thicknesses of free product were not identified in the site monitoring
wells on October 17 or 24, 2016. A measureable thickness (0.01 foot) of free
product was last detected in well MW-4A on December 1, 2015.
None of the identified concentrations of petroleum hydrocarbons exceeded their
established GCLs. The benzene concentrations identified in well MW-4A have
never exceeded the GCL for benzene of 5,000 tag/I and have decreased from 4,960
lag/I (June 2015) to 3,180 tag/I for the current sampling event. Similarly, the benzene
concentrations identified in well MW-11 have fluctuated between 4,830 lag/I and
3,570 lag/I, but have never exceeded the GCL for benzene of 5,000 lag/I.
• The general direction of groundwater flow, based on the measurements collected,
is to the east. Depth to groundwater measurements and elevations are presented
on Table 1. A groundwater contour map developed using the October 24, 2016
measurements is presented as Figure 3.
Based on the lack of measurable free product in the site monitoring wells and
groundwater concentrations consistently below the GCLs, Amec Foster Wheeler
requests that a Notice of No Further Action be issued for Incident 8109.
