SITE INFORMATION AND HISTORY
Wood (as Amec Foster Wheeler)recently completed a Phase I Environmental Site Assessment
(ESA) report for the site (dated September 14, 2017).The site consists of one parcel totaling 7.2
acres situated on the southwestern corner of the intersection of Oaklawn Avenue and Statesville
Avenue (Figure 1).The street addresses 813 Oaklawn Avenue and 1515, 1551 and 1615
Statesville Avenue are associated with the subject property. The site currently consists of
undeveloped vacant land and is located in a commercial and residential area. The 2017 Phase I
ESA assessment identified the following Recognized Environmental Conditions (RECs):
Based on our review of historical records, the site was originally developed with
residences, auto body repair facilities, a gasoline service station, a specialty chemical
company, trucking and transport facility, a drycleaner and stores since at least 1929.
From at least 1938 until 1971, McCall Street transected the subject property from north
to south. The subject property appears to have been a vacant, grass lot since at least
1976.
The Rite Aid Property (also known as NewCAMP and the Former Charlotte Army Missile
Plant) is a North Carolina Brownfields site located on the adjoining property to the east
(1776 Statesville Avenue) and is situated hydraulically upgradient from the subject site.
Chlorinated solvents were identified in the groundwater at this property related to the
historical industrial activities.
Prior assessment work performed at the subject property identified Bis(2-
ethylhexyl)phthalate and Tetrachloroethene (PCE)in the groundwater above
groundwater standards established in Title 15A NCAC 2L.0202.
Altura reported that a test pit advanced in 2005 appeared to be a possible fire or former
burn pit. Altura performed groundwater assessment in 2005 in the vicinity of the former
burn pit and identified low levels of semi-volatile organic compounds (SVOCs)in the
groundwater.
The leaking Underground Storage Tank (UST)Incident No. 36258 is considered a
historical REC because the NCDEQ issued a Notice of No Further Action.
The North Carolina Department of Environmental Quality (NCDEQ)Brownfields Program (BFP)
review of the Phase I ESA and other historical reports submitted as part of the Brownfields
Application identified data gaps. Additional assessment activities, as outlined below,were
required to assist in making risk management decisions for inclusion in the Brownfields
Agreement (BFA).The proposed assessment activities were performed in general accordance

with the most recent Inactive Hazardous Sites Branch (IHSB)Program Guidelines for Assessment
and Cleanup (http://portal.ncdenr.org/web/wm/sf/ihs/ihsguide),dated October 2015 and the
most recent versions of the U.S.Environmental Protection Agency (EPA) Region IV Science and
Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures
guidance.
2.0 ASSESSMENT ACTIVITIES
2.1 Brownfields Receptor Survey
On January 16,2019, Wood visited the subject property and surrounding area. Based on
information obtained during this reconnaissance and our previous work at the property, Wood
completed a Brownfields Receptor Survey Form (Appendix A).According to the Mecklenburg
County Well database, no private or public water-supply wells are located within a one-mile
radius of the subject property. However, during the receptor survey,Wood identified one
potential water-supply well at 1211 Spring Street, approximately 1,500 feet from the subject
property. The location of the potential well is noted on Figure 2.
2.2 Surficial Soil Sampling and Analysis
On December 13, 2018, Wood mobilized to the subject property to advance eight shallow soil
borings as recommended by NCDEQ. Locations of the soil borings are depicted on Figure 3.
Wood manually advanced the shallow soil borings using a decontaminated stainless-steel hand
auger bucket. The hand auger bucket was decontaminated between sampling locations by
scrubbing with a Liquinox®detergent solution and rinsing with distilled water.
In each of the eight borings,representative portions of samples collected at 6-inch intervals
from 0 to 2 feet below ground surface (bgs)were placed into two re-sealable plastic bags.Visual
and olfactory observations relative to the soil samples were recorded by our field personnel.The
soil types encountered in the borings were recorded to prepare soil boring logs.One plastic bag
was placed in a cooler on ice and the other plastic bag was screened in the field with a
photoionization detector (PID).Because the field screening results did not yield readings above
0 parts per million (ppm),soil samples representing 0 to 2 feet bgs (borings SS-1, SS-2, SS-4, SS-
5, SS-6, SS-7 and SS-8) were selected for laboratory analysis. Due to encountering hard material
in boring SS-3, the sample interval from 0 to 1.5 feet bgs was selected for laboratory analysis.
Soil from the corresponding plastic bags (temporarily stored on ice) were transferred to

laboratory-provided containers, placed in a cooler on ice and delivered to Con-Test Analytical
Laboratory (Con-Test) in East Longmeadow, Massachusetts for analysis. Con-Test is certified by
the State of North Carolina.
The laboratory analyzed the samples for volatile organic compounds (VOCs)by EPA Method
8260B, SVOCs by EPA Method 8270D, and Resource Conservation and Recovery Act (RCRA)
Metals (total) by EPA Methods 6020B/7471B.Additionally,four of the eight soil samples (SS-3,
SS-4, SS-5 and SS-6)were analyzed for Hexavalent Chromium by EPA Method 7196A.One field
duplicate soil sample was collected from boring SS-6 and analyzed for VOCs by EPA Method
8260B, SVOCs by EPA Method 8270D, RCRA Metals (total) by EPA Methods 6020B/7471B and
Hexavalent Chromium by EPA Method 7196A.
One “background” soil sample (BG)was collected from the 0 to 2 fee bgs interval at the location
shown on Figure 3 and analyzed for RCRA Metals (total) by EPA Method 6020B/7471B to assess
naturally-occurring metals concentrations in the soil at the subject property.
Following the completion of the surficial soil sampling activities, the borings were backfilled with
native soil to the ground surface.
2.3 Groundwater Assessment
Prior to mobilization to the property to install monitoring wells,Wood obtained a Subsurface
Investigation Permit (SIP) from the Mecklenburg County Health Department (Appendix B).Prior
to advancement of borings described in the Tasks below,Wood will first contact the North
Carolina underground utility location service (One-Call) and a private underground utility locator
to mark buried objects such as pipes, tanks or underground utility lines. The purpose of this
effort is to minimize the potential for probing into underground utilities, tanks or lines buried at
the subject property.
Wood retained a subcontract driller, Innovative Environmental Technologies, Inc. (IET)licensed in
the State of North Carolina to advance four boreholes to depths sufficient to install groundwater
monitoring wells.Wood personnel mobilized to the property with representatives of IET on
January 16, 2019 to perform the well installation. IET utilized a hollow-stem auger drilling rig to
advance the boreholes.Well MW-1 was installed near western property boundary in the vicinity
of the former drycleaners. Well MW-2 was installed near the eastern property boundary in the
vicinity of the former filling/auto station which is also downgradient of the eastern adjacent

Former CAMP site. Well MW-3 was installed along Oaklawn Avenue near the former filling
station. Well MW-4 was installed in the southern portion of the boundary in the vicinity of the
former paint shop.The monitoring well locations are shown on Figure 3.
Based on the depth to groundwater measured in each of the boreholes on this date, the wells
were installed to depths ranging from 20 to 25 feet bgs.Wells MW-2 and MW-4 were installed
at the locations of soil boring/samples SS-2 and SS-4,respectively.Wood personnel examined
soil cuttings during drilling to assist in preparing boring/well construction logs.
At each location, the subcontract drilling crew installed two-inch diameter PVC well screens and
risers into the approximate 8-inch diameter boreholes to collect groundwater samples for
laboratory analysis. A filter sand pack was placed around each well screen to at least two feet
above the top of the screened interval. A bentonite seal was placed above the sand pack.
Portland cement was mixed and placed in the annulus of the borehole above the bentonite seal
to land surface. A concrete pad (approximately 2 feet by 2 feet) was constructed at each well
head.Each well was completed with a steel flush-mounted manhole cover to allow for vehicular
traffic such as lawn mowing equipment.The well construction records are included as Appendix
B.A locking cap and lock was placed on each well.IET personnel developed each of the wells by
pumping to reduce the turbidity of the groundwater.
Wood personnel use a survey level to establish the top of casing elevation of each well relative
to a known datum elevation (stormwater sewer manhole at the corner of the intersection of
Spring street and Oaklawn Avenue). Subsequent water level measurements taken in each well
were used to calculate the groundwater elevation. The groundwater elevation data for each well
was used to determine the groundwater flow direction.
Following development,Wood collected samples of groundwater from each well using low-flow
purging techniques in general accordance with the Environmental Protection Agency (EPA)
Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and
Technical Procedures guidance.During purging, groundwater field parameters were collected
using an YSI ProPlus water quality meter with commercially-manufactured flow cell and an HFS
MicroTPI turbidity meter. Groundwater field parameters collected through the flow cell included
pH, specific conductivity, dissolved oxygen, temperature and oxidation reduction potential
(ORP).

Turbidity measurements were collected prior to the groundwater entering the flow cell.Field
sampling data sheets are included as Appendix C.Following completion of purging,
groundwater samples were collected from the monitoring wells, placed in laboratory-provided
containers.The groundwater samples were labeled with a unique ID and placed in an ice-filled
sample cooler and delivered to Con-Test for analysis. The samples were maintained under chain-
of-custody protocol. The groundwater samples were analyzed for VOCs by EPA Method 8260B
and SVOCs by EPA Method 8270D.Two of the groundwater samples (MW-2 and MW-4),were
analyzed for RCRA Metals (total) by EPA Method 6020B/7471B to establish baseline metals
concentrations in the groundwater at the subject property.One field duplicate QA/QC sample
(DUP-1)was collected from well MW-2 and analyzed for VOCs, SVOCs and metals. A trip blank
was analyzed for VOCs.
Soil cuttings and development/purge water generated during these activities were spread on
the ground surface at the property.
3.0 RESULTS
3.1 Soil Results
The constituents detected in the soil samples are summarized in Table 2.A copy of the
laboratory report describing these results is included in Appendix D.The results of the analysis
identified the following:
No detectable concentrations of VOCs above the NCDEQ IHSB Preliminary Soil
Remediation Goals (PSRGs).
One sample, SS-8 identified an estimated concentration (0.17 mg/kg)of benzo (a)
pyrene that exceeded both the Residential Use Health Based and Protection of
Groundwater PSRGs.
A concentration of total chromium (40 mg/kg) was identified in the “background” soil
sample (BG). Concentrations of total chromium identified in soil samples SS-1 through
SS-8 ranged from 51 to 230 mg/kg. These are within the range of “naturally-occurring”
concentrations in this region according to published literature. Four soil samples were
additionally tested for hexavalent chromium. Hexavalent chromium was identified in only
one (SS-5) at a concentration of 4.9 mg/kg. This concentration exceeded both the
Residential Use Health Based and Protection of Groundwater PSRGs for hexavalent
chromium.

Concentrations of total arsenic were identified in soil samples SS-1 through SS-8 ranging
from 0.9 to 3.0 mg/kg. These are within the range of “naturally-occurring” concentrations
in this region according to published literature.
3.2 Groundwater Results
Based on the January 18, 2019 groundwater elevation measurements, groundwater at the site
flows generally to the west. A summary of groundwater elevations is included in Table 1, and a
groundwater contour map is included as Figure 4.
The constituents detected in groundwater are summarized in Table 3.A copy of the laboratory
report describing these results is included in Appendix D. The results of the analysis identified
the following:
Concentrations of benzene, ethylbenzene, naphthalene, 1,2-dichloroethane (1,2-DCA),
isopropylbenzene, n-propylbenzene and trichloroethene (TCE) in the groundwater
sample collected from well MW-3 exceeded their respective NC 2L Standards.The
benzene and naphthalene concentrations also exceeded Non-Residential Vapor Intrusion
Groundwater Screening Levels (GWSLs), while the benzene, ethylbenzene, TCE and
naphthalene concentrations exceeded the Residential GWSLs.
A concentration of Tetrachloroethene (PCE) in the groundwater sample from well MW-1
exceeded the NC 2L standard and the Residential GWSL.
A concentration of TCE in the groundwater sample from well MW-1 exceeded the NC 2L
standard and the Non-Residential and Residential GWSLs.
