1 BACKGROUND

The site is located at 2410 Randolph Avenue, Greensboro, Guilford County, North Carolina as
displayed on Figure 1. Valley Proteins, Inc. - Carolina By-Products (CBP) currently owns the
property and leases the site to Chemol Company, Inc. (Chemol). The site formerly had six
underground storage tanks (USTs) that contained methanol and n-butanol. Chemol personnel
suspected that the USTs had lost integrity due to the presence of water in one of the USTs. Data
collected during the UST removal in March 1991 and the subsequent soil sampling confirmed the
release of alcohols to the subsurface. Further environmental sampling confirmed both soil and
groundwater contamination.

Water and sewer services are reportedly provided by the City of Greensboro to all residences and
businesses in the area. There are no reported water supply wells in use in the area. The site is
located within an industrial area of the City of Greensboro.

A Soil Vapor Extraction (SVE) system was installed at the site in late 1992 to remediate the affected
soils. The SVE system consisted of a vapor extraction trench over the area of the former USTs.
Analysis of soil samples collected during completion of the Comprehensive Site Assessment did not
detect contaminant concentrations above the Industrial/Commercial Soil Cleanup Levels.

A groundwater investigation at the site consisted of the installation of 10 monitoring wells. Analysis
of samples collected from the wells during the Comprehensive Site Assessment detected
concentrations of methanol and n-butanol above the state groundwater quality standards. As a
result of the groundwater exceedances, the North Carolina Department of Environmental Quality
(NCDEQ) requested Valley Proteins prepare a corrective action plan to remediate the
groundwater.

On June 8, 2004, Kleinfelder, Inc. (formerly Trigon Engineering Consultants, Inc.) submitted a
Corrective Action Plan (CAP) to the NCDEQ on behalf of Valley Proteins. The CAP proposed
allowing the alcohols and volatile hydrocarbons detected in the groundwater to naturally attenuate
over time and to monitor groundwater quality through annual groundwater sampling events. The
CAP was approved by the NCDEQ on October 11, 2004.

During the July 2008 sampling event, contaminant concentrations were detected above the 2L
Standards in several monitoring wells. Therefore, in compliance with the August 11, 2008,
correspondence from Ms. Cindy Rintoul of the NCDEQ DWM UST Section, Kleinfelder
implemented a semi-annual monitoring schedule and included 2 additional monitoring wells
CMW-1 and CMW-8. Following three consecutive sampling events with concentrations below the
2L Standard, Kleinfelder recommended removing CMW-1 and CMW-8 from the sampling
schedule. In July 2010, following six sampling events of either clean samples or below State
Standards, CMW-7 was removed from the sampling schedule.

The March 19, 2012, letter from Ms. Carin Kromm of the NCDEQ DWM UST Section requested
a new monitoring well across the street from CMW-10. The new well, CMW-11, was installed on
December 6, 2012.

Kleinfelder has completed semi-annual groundwater monitoring events in February and
December of 2012, July of 2013, February and July of 2014 and 2015, March and August of 2016,
February and July of 2017, June of 2018, May of 2019, May 2020, and May of 2021. Methanol
and VOCs remain present above the 2L Standard with the highest concentrations in monitoring
well CMW-9 and CMW-3. After the July 2017 groundwater monitoring event, Kleinfelder
recommended the sampling schedule switch to annual monitoring from semi-annual monitoring.
The NCDEQ approved this change in a letter dated August 21, 2017.

2 FIELD ACTIVITIES

On May 13, 2021, eight monitoring wells were sampled according to the sampling schedule shown
in Table 1. The locations of the monitoring wells are shown on Figure 2. Prior to collecting the
samples, the depth to groundwater was measured in all the monitoring wells using an electronic
water level indicator accurate to 0.01 feet. The wells were purged using a submersible pump and
disposable polyethylene tubing until three well volumes had been removed or the well was
pumped dry. Samples were placed into pre-preserved laboratory provided containers, labeled,
and maintained on ice until delivery to Prism Laboratories, Inc. (Waypoint Labs) in Charlotte,
North Carolina for chemical analysis. Each sample was analyzed for volatile organic compounds
using EPA SW846 Method 8260; and CMW-9, CMW-10, and CMW-11 were analyzed for
methanol using modified EPA Method 8015.

3 RESULTS

3.1 GROUNDWATER FLOW DIRECTION
The groundwater measurements performed on May 13, 2021, were used to prepare a
potentiometric surface map shown on Figure 3. The monitoring well and groundwater elevation
data are summarized in Table 2. Groundwater levels across the site were generally shallower
than those measured on May 1, 2020 sampling event. Groundwater is generally moving east as
depicted in Figure 3. The horizontal hydraulic gradient calculated between monitoring wells
CMW-2(E) and CMW-5 is 0.065 foot/foot. The hydraulic conductivity, measured by the HSMM
Group, in the source area of the release ranged from approximately 4.5 to 16 feet per year
(4.35x10-6 to 1.55x10-5 cm/sec), with the hydraulic conductivities slightly higher in the
downgradient wells (CMW-4 and CMW-5). The estimated groundwater velocity across the site
ranges between approximately 0.92 to 3.25 feet per year based upon an assumed effective
porosity of 30 percent.

3.2 GROUNDWATER SAMPLING RESULTS
Laboratory analysis detected methanol in CMW-9 at a concentration exceeding the 2L Standard
and GCL, but at lower concentrations than the May 2020 sampling event. The methanol
concentration in CMW-10 was below the detection limit. Volatile organic compounds were
detected above the laboratory method detection limits in all monitoring wells sampled.
Concentrations of one or more compounds detected in CMW-2(E), CMW-3, CMW-6, CMW-9, and
CMW-10 exceeded the 2L Standards. The laboratory results of the May 13, 2021 sampling event
are summarized in Table 3. The laboratory report is included in Appendix A.

To track the methanol concentrations over time, graphs were constructed for the monitoring wells
where methanol concentrations have historically exceeded the 2L Standard. Graphs showing
methanol concentrations in monitoring wells CMW-9 and CMW-10 are included as Figures 4 and
5. Concentrations of tetrachloroethene (PCE) in the bedrock monitoring well CMW-9 appear to
show a generally decreasing trend, while benzene shows a slight decrease in the May 2020 and
May 2021 sampling events as compared to the generally decreasing trend observed from mid-
2005 through June 2018 (Figure 6). The daughter product cis-1,2 dichloroethene (cis-1,2 DCE)
appears to show a decrease from the May 2020 event in CMW-9 as displayed on Figure 6. The
benzene plume appears to be migrating in the fractured bedrock from the Curtis Packing

20201208.001A | RAL21R127197 Page 5 of 8 June 23, 2021

Company incident located south of the site. The PCE plume appears to be migrating in the
bedrock fractures from the off-site PCE incident at Precision Fabrics Group south of the site. The
concentrations of vinyl chloride in monitoring wells CMW-2 and CMW-3 appear to continue to
stabilize or decrease, as displayed on Figure 7. The concentration of vinyl chloride in CMW-3 was
detected at about the 2L Standard and GCL, with an increase since the May 2020 event. Vinyl
chloride was also detected in monitoring well CMW-9 above the 2L Standard. The presence of
vinyl chloride may be an indication of the reductive dechlorination process associated with
degradation of PCE in the subsurface. Historical laboratory results for each of the monitoring wells
are summarized in Table 4.

3.3 PLUME GEOMETRY
Based on the May 13, 2021 sampling results and historical data, methanol has historically been
detected in CMW-2(E), CMW-3, CMW-9, CMW-10, and CMW-11 with the highest concentrations
being detected in monitoring well CMW-9. During this sampling event, monitoring well CMW-9,
CMW-10, and CMW-11 were analyzed for the presence of methanol. Methanol was detected in
only monitoring well CMW-9 above the 2L Standard. The concentration of methanol detected in
monitoring well CMW-9 decreased from the May 2020 event, and remains above the GCL.

n-Butanol was detected in monitoring well CMW-9 above the 2L Standard. The concentration of
n-Butanol detected in monitoring well CMW-9 has decreased significantly over the course of the
past four sampling events. n-Butanol was not detected in any other monitoring wells above the
2L Standard during the May 2021 sampling event. No n-Butanol concentrations were detected
above the GCL.

Other volatile organic compounds (VOCs) were detected in all the monitoring wells that were
sampled. The highest concentrations of VOCs were detected in CMW-3, CMW-9, and CMW-10.
The core of the plume is situated around CMW-3 and CMW-9 with a large, diffuse plume
extending towards CME-2(E), CMW-5, and CMW-6. None of the other VOC concentrations
detected were above the GCLs, except for vinyl chloride detected in monitoring well CMW-3.

4 CONCLUSIONS

Based on the results of the May 13, 2021 annual sampling event, Kleinfelder has drawn the
following conclusions:
 Chlorinated solvents from an offsite release were detected in CMW-2(E), CMW-3,
CMW-9, and CMW-10 at concentrations exceeding the 2L Standards. None of the
concentrations detected were above the GCLs, except for vinyl chloride in CMW-3.
 Other VOCs, including benzene, from an offsite release were detected in CMW-2(E),
CMW-3, CMW-6, CMW-9, and CMW-10 at concentrations exceeding the 2L
Standards but below the GCLs.
 n-Butanol was detected in the bedrock well CMW-9 at a concentration above the 2L
Standard, but below the GCL.
 Methanol was detected at concentrations above the 2L Standard and GCL in
monitoring well CMW-9. The methanol concentration in CMW-9 showed an decreased
from the May 2020 sampling event.

5 LIMITATIONS

Kleinfelder offers various levels of investigative and engineering services to suit the varying needs
of different clients. It should be recognized that definition and evaluation of geologic and
environmental conditions are a difficult and inexact science. Judgments leading to conclusions
and recommendations are generally made with incomplete knowledge of the subsurface
conditions present due to the limitations of data from field studies. Although risk can never be
eliminated, more detailed and extensive studies yield more information, which may help
understand and manage the level of risk. Since detailed study and analysis involves greater
expense, Kleinfelder’s clients participate in determining levels of service that provide adequate
