The former Red Apple Market #21 site is located along NC Highway 561 West in Saint John, Hertford County,
North Carolina (Figure 1). Two 1,000-gallon gasoline USTs and one 550-gallon gasoline UST were removed
from the site in October 1992. In addition, one 550-gallon gasoline UST was closed in-place in October 1992.
The site risk classification is currently High due to the presence of potable water supply wells within a 1,000-foot
radius of the site.
A Mobile Multi-Phase Extraction (MMPE) event was conducted between October 13 and October 17, 2014, by
Greenwood Applied Services (GAS) on MW-2R, MW-3R, MW-4R and MW-5R, under the supervision of
Geological Resources Inc. (GRI) personnel. A free product thickness of 0.02 feet was measured in MW-4R prior
to the start of the event. No measurable free product was observed in MW-2R, MW-3R or MW-5R. A total of
9,500 gallons of affected ground water was recovered during the MMPE event. Approximately 4 gallons of free
product were observed in the tanker at the conclusion of the MMPE event. Upon conclusion of the event, a free
product thickness of 0.09 feet was observed in MW-4R. No measurable free product was observed in MW-2R,
MW-3R or MW-5R. The average fluid recovery rate was 98.96 gallons per hour. Based on mass-removal
calculations, an additional 1.38 gallons of vapor phase hydrocarbons were removed during the event.
Once GRI receives the results of the ground water sampling event that is tentatively scheduled for November
2014, the overall effectiveness of the MMPE event can be determined.

1.0 SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to present the results of a Mobile Multi-Phase Extraction (MMPE) event conducted
between October 13 and 17, 2014 at the former Red Apple Market #21 site, located along NC Highway 561 West
in Saint John, Hertford County, North Carolina (Figure 1). The activities were conducted in accordance with
Geological Resources, Inc. (GRI) Proposal No. 14-397, which was submitted to NCDENR on July 23, 2014 and
approved as Task Authorization No. 9785-060 on October 2, 2014. The purpose of the activities was to remove
free product and reduce contaminant concentrations in monitoring wells MW-2R, MW-3R, MW-4R and MW-5R.
According to available information, two 1,000-gallon gasoline and one 550-gallon gasoline underground storage
tanks (USTs) were removed from the site in October 1992. In addition, one 550-gallon gasoline UST was closed
in-place in October 1992. Twenty-seven Type II monitoring wells (MW-1 through MW-6, MW-8 through MW-
23, MW-25 and MW-27 through MW-30), one Type III monitoring well (MWD-7) and three recovery wells
(RW-1 through RW-3) were installed at the site during past ground water assessment and remediation activities.
A total of 4,381.57 tons of contaminated soil was removed from the site between May 16 and June 2, 2011. Prior
to the May-June 2011 soil excavation, monitoring wells MW-1 through MW5, MWD-7 as well as recovery wells
RW-1 and RW-3 were abandoned. Monitoring wells MW-1R through MW-5R were installed following the
completion of the May-June 2011 excavation activities. Please note, monitoring wells MW-6, MW-11, MW-12,
MW-13 and MW-29 were destroyed during past site activities. Ground water samples collected from monitoring
wells at the site and nearby water supply wells have exceeded the maximum allowable concentrations (MACs)
during past sampling events. Free product has been historically reported in monitoring wells MW-2, MW-3,
MW-5, MW-2R, MW-3R, MW-4R and MW-5R.
Please note that certain information contained in this report was obtained under the supervision of previous
consultants. Although GRI cannot verify the accuracy of information obtained from previous reports, for the
purpose of this report, it is assumed to be correct. A Site Map showing the locations of the monitoring wells and
the structures on-site and on surrounding properties has been included as Figure 2. Please refer to previous
submittals for further historical information regarding the site.

2.0 MMPE EVENT
A MMPE event was conducted at the site by Greenwood Applied Services (GAS) under the supervision of GRI
beginning on October 13, 2014 and ending on October 17, 2014. The MMPE equipment included a liquid ring
pump, 9,500-gallon capacity tanker, flexible vacuum hoses, 1-inch diameter PVC stinger pipes and associated
couplings and pipe fittings to manifold to four monitoring wells (MW-2R, MW-3R, MW-4R and MW-5R). The
MMPE system was rated at 24in./Hg at 280 cfm. Monitoring wells MW-2R, MW-3R, MW-4R and MW-5R
were gauged on October 13, 2014 prior to the event. A free product thickness of 0.02 feet was measured in MW-
4R prior to the start of the event. No measurable free product was observed in MW-2R, MW-3R or MW-5R.
The stinger pipes were set at depths of 15.48, 16.23, 15.07 and 15.85 feet in MW-2R, MW-3R, MW-4R and
MW-5R, respectively.
Monitoring wells MW-2R, MW-3R, MW-4R and MW-5R were vacuumed continuously for a total of 96 hours
during the event. Measurements of relative humidity, temperature, vacuum, exhaust velocity, and off-gas
concentrations were recorded at the discharge stack at a minimum of two times per 24-hour period. Vacuum at
the extraction wells ranged from 22 to 28 in./Hg. Exhaust velocities ranged from 161 to 1,167 fpm.
Temperatures ranged from 92.3 to 131.2ºF and relative humidity ranged from 37.8 to 100.0 percent. Total VOC
off-gas concentrations ranged from 269.0 to 1,504 ppm during the event. At the conclusion of the event, no
measurable free product was observed in MW-2R, MW-3R or MW-5R; however, a free product thickness of 0.09
feet was measured in MW-4R. A summary of well construction and gauging data obtained before start up and at
the conclusion of the MMPE event is presented in Table 1. A copy of the MMPE data and calculations has been
included as Appendix A.
The results of the MMPE event indicate that a total of 9,500 gallons of liquid was removed during the event. Of
the 9,500 gallons of liquid recovered, 4 gallons of free phase product were present in the tanker. Based on 96
hours of operation, the average fluid recovery rate was 98.96 gallons per hour. Based on mass-removal
calculations, an additional 8.64 pounds or 1.38 gallons of vapor phase hydrocarbons were removed. Based on 96
hours of operation, an average of approximately 0.01 gallons of vapor phase hydrocarbons was removed per hour
by the MMPE system. Based on the October 2014 MMPE event, the cost of free product and contaminated
ground water recovered per gallon was $1.06. A summary of free product recovery results has been included as
Table 2. A summary of information collected during the MMPE event as well as a breakdown of fluids removed
3
is included as Table 3. A summary of costs associated with free product recovery is included as Table 4. At the
conclusion of the MMPE event, all wastewater was transported to a permitted facility for disposal. Copies of
disposal manifests have been included as Appendix B.
3.0 CONCLUSIONS AND RECOMMENDATIONS
A total of 9,500 gallons of affected ground water was recovered during the MMPE event conducted
between October 13 and 17, 2014. Of the 9,500 gallons recovered, 4 gallons of free product were
observed in the tanker at the conclusion of the event. The average fluid recovery rate was 98.96 gallons
per hour. Based on mass-removal calculations, an additional 8.64 pounds or 1.38 gallons of vapor phase
hydrocarbons were removed at an average of approximately 0.01 gallons per hour by the MMPE system.
Based on the October 2014 MMPE event, the cost of free product and contaminated ground water
recovered per gallon was $1.06. Upon conclusion of the event, no measurable free product was observed
in MW-2R, MW-3R or MW-5R; however, a free product thickness of 0.09 feet was measured in MW-
4R.
Based on the above information, the MMPE removed contaminated ground water and free product from
monitoring wells MW-2R, MW-3R, MW-4R and MW-5R. GRI personnel will return to the site in
November 2014 to conduct a comprehensive ground water sampling event. Once the data from the
November 2014 sampling event are evaluated, the overall effectiveness of the MMPE event will be
evaluated.
