Re: Limited Phase II Environmental Site Assessment - Addendum
18.56-Acre Beazer Property
Charlotte, North Carolina

Dear Mr. Justice:
ERM NC, PC (ERM) is pleased to present the results of the additional site
assessment work that was performed subsequent to the completion of
ERM’s Phase II Soil and Groundwater Assessment report (Phase II), dated
September 9, 2010. The subject property is an 18.56 acre property
(comprised of 10 parcels) located near uptown Charlotte, North Carolina
(see Figure 1).
BACKGROUND
The purpose of the Phase II ESA was to assess the subject property for
potential soil and groundwater impact associated with historical
automobile repair and maintenance facilities and historic manufacturing
uses of surrounding properties. Tetrachloroethene (PCE) was detected in
three soil borings at concentrations ranging from 22 micrograms per
kilogram (µg/kg) to 47 µg/kg. These concentrations exceed the North
Carolina Department of Environment and Natural Resources (NCDENR)
Inactive Hazardous Sites Branch (IHSB) Soil Remediation Goal for the
Protection of Groundwater of 5 µg/kg. In addition, groundwater
samples collected from nine temporary monitor wells installed on the
subject property in July and August 2010 detected trichloroethene (TCE)
at concentrations ranging from 1.7 micrograms per liter (µg/L) to 410
µg/L. The North Carolina Administrative Code (NCAC) 2L
Groundwater Standard (2L Standard) for TCE is 3 µg/L.
Mr. Max Justice
October 11, 2010
Page 2

Clarkson Street, LLC requested the installation of two additional
temporary monitor wells to further evaluate the lateral extent of TCE
impacted groundwater on the subject property in the vicinity of Parcel
Nos. 07314201 and 07325501.
PHASE II ADDENUM ACTIVITIES

Boring B-21 was drilled with air rotary drill rig due to anticipated
shallow bedrock at this location. Partially weather rock was encountered
at approximately seven feet below ground surface (bgs) and fractured
bedrock was encountered at approximately 15 feet bgs. B-21 was
advanced until groundwater was encountered at approximately 40 feet
bgs.
Boring B-22 was drilled with a Geoprobe® drill rig capable of advancing
hollow stem augers and air rotary equipment. Boring B-22 was located
on top of a soil stockpile that was approximately 20 feet above the
surrounding land surface. The boring was initially drilled with hollow
stem augers to minimize disturbance of the stockpile. The augers were
changed to air rotary at approximately 47 feet below the top of the
stockpile (27 feet bgs) as this depth was near the limit of auger
capabilities for the Geoprobe. The air rotary drill rods, equipped with a
4-inch button bit, were then advanced to approximately 57 feet below the
top of the stockpile (37 feet bgs), where groundwater was encountered.
Bedrock was not encountered during the advancement of B-22. Soil
types included mixtures of sand, silt, and clay. Soil cuttings generated
from B-21 and B-22 were placed in 55-gallon drums, sealed, and properly
labeled for temporary on-site storage. Figure 2 illustrates the locations of
B-21 and B-22 as well as previous temporary monitor wells installed
during Phase II activities.
Temporary monitor wells were constructed in both of the boreholes
using 2-inch inner diameter (I.D.) Schedule 40 PVC flush-threaded casing
and well screen. Ten feet of 0.010-inch slot well screen and a threaded
end cap were placed at the bottom of the borehole. The remainder of the
well was completed using solid PVC casing to a height of approximately
two feet above the ground surface. The annular space around the wells
was then filled with a washed and graded medium sand to a minimum
of two feet above the top of the screen. Lithologic description logs for B-
21 and B-22 are provided as an attachment to this report.
Once groundwater elevations stabilized in the wells, ERM utilized a
submersible pump to remove fines from the well casing and sand pack.

Approximately 20 gallons of water were pumped from each well during
development activities. Development water from B-21 and B-22 was
containerized and left on-site in properly labeled and sealed in 55-gallon
drums.
Once the temporary wells were developed and allowed to recharge to the
initial depth to water measurement, ERM utilized new disposable
polyethylene bailers and twine to collect groundwater samples. The
samples were placed in laboratory-provided containers and packed in a
cooler with sufficient ice to maintain a temperature of 4º Celsius and sent
via courier to Shealy Environmental Services in West Columbia, South
Carolina for analysis using EPA Method 8260 for volatile organic
compounds (VOCs).
Once the temporary monitor wells were sampled, the drilling contractor
removed the PVC pipe from each borehole and abandoned the borings
with neat cement in accordance with state standards.
GROUNDWATER ANALTYICAL RESULTS
TCE was detected in B-21 at 2.3 µg/L, which is below the 2L Standard of 3
µg/L. No VOCs were detected in the B-22 sample. Based on these
results, the TCE plume is present in shallow groundwater on Parcel No.
07314201. Table 1 summarizes analytical results from B-21 and B-22 as
well as previous temporary monitor wells installed during Phase II
activities. The complete laboratory reports are included as an attachment
to this report.
ERM appreciates the opportunity to be of service on this important
project. Please contact us with any questions regarding the information
presented in this addendum report.
Sincerely,

Rick Tarravechia, P.G. Michael Pressley, P.G.
