Subject: Focused Phase II Site Assessment Report
Property at US Highway 74 and Old Caroleen Road
Forest City, North Carolina
Dear Mr. Lew:
The Phase I Environmental Site Assessment for the Forest City, NC, property conducted by ENVIRON in
2010 identified three recognized environmental conditions (RECs). These were:
• PCE in the groundwater: PCE has been detected in historical samples collected from wells in the
central-eastern portion of the property, with concentrations ranging between 1.6 ppb to 47 ppb. In
addition, PCE had been detected more than 10 years ago at 2.8 ppb in a well in the northeastern
comer of the facility -PCE was not detected in a more recent sampling of that well.
• Elevated metals in soil and groundwater: Concentrations of inorganic constituents at
concentrations greater than default NC remediation goals have been detected in a few soil and
groundwater samples at the site. In general, the detected concentrations have been only slightly
greater than the default criteria, with the exception of a detection of arsenic in soil in a supposedly
unimpacted location at 4 feet below ground surface. The concentration of arsenic detected in that
soil sample was 250 ppm, approximately l 00 times the default criterion (that data point was
considered an "anomaly" when reported by the consultant that collected the sample).
• Soil impacted by diesel fuel: The confirmation samples from the closure activities associated with
a 250-gallon diesel fuel AST indicated that a small volume of petroleum-impacted soil remains in
the former vicinity of the AST.
To assess the potential magnitude of these environmental conditions, ENVIRON conducted a focused
Phase II site assessment in September 2010. The purposes of the focused Phase II included confirmation
of historical results and to obtain information about potential contamination in proximity to the Mako
building and deeper aquifer. To those ends, soil samples were taken from and wells were located near
areas of potential concern (such as the Mako building and the previously-observed PCE groundwater
contamination). The focused Phase II included the following activities:
• Installation of six Type II groundwater monitoring wells (using a combination of direct push
drilling techniques [DPT], and hollow stem auger, rock coring, and air hammer drilling
equipment);
• Installation of four Type III groundwater monitoring wells in bedrock (using a combination of
hollow stem auger, rock coring, and air hammer drilling equipment);
• Collection soil samples during boring advancement and field analyzed with a photo-ionization
detector (PID);

• Based on PID readings and field observations, submission of eight soil samples for laboratory
analysis of volatile organic compounds (VOCs) using USEPA Method 8260 and RCRA Metals
using USEPA Method 6010;
• Collection of groundwater samples from the 10 newly-installed monitoring wells and 17
previously existing wells using low-flow sampling techniques; and,
• Submission of groundwater samples for laboratory analysis of volatile organic compounds
(VOCs) using USEPA Method 8260 and RCRA Metals using USEPA Method 6010.
The sampling locations are shown on Figures 1 and 2 (all locations are shown on both figures; Figures IA
and 2A present the information regarding the central-eastern portion of the property at an enlarged scale),
and the sampling locations/sample identifications for the soil samples collected and the newly-installed
monitoring wells are as follows:

Information regarding the wells, including the depth to groundwater, is presented in Table 1.
All samples (soil and groundwater) were preserved in accordance with their respective analytical method
requirements, placed on ice, and shipped over-night to the TestAmerica laboratory in Nashville, TN for
analysis.
The results of the soil sampling indicate that impacts to the soil at the site, if any, are relatively minimal in
both nature (in terms of the constituents detected) and extent (in terms of the area that might be impacted.
The results of the recent soil sampling activities are presented in Table 2 (those results are compiled with
the results from available historic soil sampling activities in Table 3).
The results of the groundwater sampling indicate that impacts to the groundwater are very limited,
primarily associated with PCE in the central-eastern portion of the property. Even so, the concentrations

in all but one of the six wells in which PCE was detected in 2010 were less than 10 ppb, with a
concentration of PCE in TW-1of34.3 ppb (a reduction from 46.8 ppb in November 2009).The results of
the recent groundwater sampling activities are presented in Table 4 (those results are compiled with the
results from available historic groundwater sampling activities in Table 5) .

extent of groundwater contamination. Specifically. a bedrock well in the vicinity of
the contaminant plume would be necessary to delineate the vertical extent of
PCE-impact. In addition , one or more wells terminated on the bedrock interface
and located hydraulically downgradient of the known contaminant plume would
be necessary to determine the downgradient extent of impacted groundwater. It
may be necessary to construct a road down the steep slope and onto the flood
plain of the river to place these wells. Finally, it may be necessary to sample the
river itself to determine if impacted groundwater is discharging into the river.
If you .should have any questions about the findings of our assessment work, please
contact me at [phone].

Groundwater Sampling Activities

After each round of well installation. Mid-Atlantic personnel collected groundwater samples
from the newly installed wells. Mid-Atlantic measured the depth lo water in each of the
wells to be sampled using a decontaminated electronic water level indicator. Groundwater
parameters. including temperature. oxidation reduction potential (ORP). electrical
conductivity (EC). and pH, were also measured in the field and are summarized in the field
notes contained in Appendix B.
New nitrile gloves were worn during the collection of each sample. The monitoring wells
were purged of at least three volumes of water or to dryness, using dedicated disposable
bailers. immediately prior to sampling. Groundwater samples were colleded and placed in
laboratory-supplied containers, placed into an ice-filled cooler, and transported under
chain~f-custody to SGS Environmental Services. Inc. (SGS) of VVilmington, North
Carolina. At the laboratory, the samples were analyzed for volatile organic compounds
(VOCs) according to EPA Method 601 .
•
The results are summarized in Table 3 and documented in Appendix C. As summarized,
of the twelve wells installed and sampled, samples collected from four wells (MW-8 and
MW-10 through MW-12) exhibited PCE concentrations in excess of its NCGQS. The
groundwater samples collected from the original well, lW-1, exhibited tetrachloroethene •
(PCE) at concentrations ranging from 39 micrograms per liter (ug/L) to 46.8 ug/1 , all of
which exceed rts established NCGQS of 0.07 ug/L. The samples from wells MW-8 and
MW-10 through MW-12 exhibited PCE at concentrations ranging from 4.79 ug/L (in well
MW-12) to 8.41ug/L in well MW-10. A PCE isoconcentration map depicting the estimated
area of PCE impact is included as Drawing 4.
Conclusions
• Groundwater in the vicinity of the former sludge drying beds and former waste
filtering beds has been adversely impacted by PCE In excess of its NCGQS of 0. 7
ug/L.
• Although the source of PCE has not been determined, it's probable that it
originated from the vicinity of the former sludge drying bed, which is located about
100 feet hydraulically upgradient of the most upgradient impacted monitoring well.
MW-11 .
• The groundwater contaminant plume is migrating toward the north/northeast.
toward the Second Broad River. The downgradient extent of impacted groundwater
has not been determined due to the steepness of the topography in that direction.
• A more detailed assessment would be necessary to determine the degree and •
