EXECUTIVE SUMMARY
The former Ya Ya #2 site is located at 6283 Highway 301 South in Hope Mills, Cumberland County, North
Carolina. The site is currently owned and operated by Gamil Nagi Al Dalali as a petroleum retail facility.
One 1,000-gallon gasoline UST and one 2,000-gallon gasoline UST were removed in May 2005. Currently,
one 11,000-gallon gasoline UST and one 4,000-gallon gasoline UST are active at the site. According to
NCDEQ personnel, a previous release from the UST system had been reported.

On September 15, 2020, an updated receptor survey was conducted. According to the information
obtained during receptor survey activities, twenty-one potable water supply wells were identified within
1,000 feet of the source area. Of those twenty-on water supply wells, one water supply well is located
within 250 feet of the site. Public water is not available to the site or surrounding properties within a
1,500-foot radius of the site. The adjoining properties are single family residential or commercial
properties. A CAP has not been completed for this incident.

On March 22, 2023, two shallow Type II monitoring wells and two deep Type II monitoring wells were
gauged, purged, and sampled. Free product was not observed. Contaminant concentrations that
exceeded MACs were reported in the ground water samples collected from MW-11R, MW-12, DMW-21,
and DMW-27. All of the reported contaminant concentrations were below the GCLs.

Based on this information, a comprehensive sampling event should be conducted in September 2023 that
includes natural attenuation parameters to provide data for evaluation of the most cost-effective
approach for remediation.

1.0 SITE HISTORY AND CHARACTERIZATION
Geological Resources, Inc. (GRI) presents the results of the March 2023 ground water sampling event at
the former Ya Ya #2 site located at 6283 Highway 301 South in Hope Mills, Cumberland County, North
Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 22-878, which
was submitted to the North Carolina Department of Environmental Quality (NCDEQ) on February 22, 2023,
and approved as Task Authorization No. 29195-21 on February 23, 2023. State correspondence is included
in Appendix A.

According to NCDEQ personnel, a previous release from the UST system had been reported at the site.
Several owners/operators have managed the site since the release was reported. The current
owner/operator reportedly purchased the site in 2001. According to NCDEQ personnel, site assessment
activities, including a comprehensive site assessment, were initially conducted under the Federal Trust
Fund Program. Three water supply wells were affected by the release. However, these water supply wells
were either taken out of service or abandoned and replaced with new wells.

On May 25, 2005, GRI supervised the removal of one 2,000-gallon gasoline UST and one 1,000-gallon
gasoline UST from the site. Approximately 268 tons of affected soil were excavated during the closure
activities. Phase II Limited Site Assessment activities were conducted between August 24 and September
9, 2005.

Please note that information regarding the site prior to 2005 contained in this report was obtained under
the supervision of previous consultants. Although GRI cannot verify the accuracy of this information, for
the purposes of this report it is assumed to be correct.

The site is currently owned and operated by Gamil Nagi Al Dalali as a petroleum retail facility. Currently,
one 11,000-gallon gasoline and one 4,000-gallon gasoline USTs are active at the site. UST owner/operator
information and UST system information are included as Tables 1 and 2, respectively. The Registered
Tank Report is shown below:

A total of twenty-five Type II monitoring wells and eight Type III monitoring well were installed at the site
during past ground water assessment activities. Monitoring wells MW-3, MW-4, MW-5, MW-6R, MW-8,
MW-10, MW-13, MW-14, DMW-28, and MW-30 were reported to be damaged and/or destroyed and
therefore have not been sampled.

The site and surrounding area is a mixture of single family residential and commercial properties. The site
contains one building and is primarily capped with concrete and asphalt. The overall topography at the
site is relatively flat.

On September 15, 2020, GRI personnel conducted an updated receptor survey at the site. Twenty-one
active potable water supply wells (SW-1, SW-2B, SW-3 through SW-10, SW-12, SW-13, SW-15 through
SW-18, SW-20, SW-21, SW-22A, and SW-26) were identified within a 1,000-foot radius of the site.
Municipal water is not available to the site or surrounding properties. The site does not lie within a
designated wellhead protection area. Water supply well owner information is presented in Table 3.
Adjacent property owner information is presented in Table 4. A Site Vicinity Map showing the locations
of water supply wells and property boundaries has been included as Figure 2. A Site Map showing the
locations of the monitoring wells and the structures on-site has been included as Figure 3.

To date, a CAP has not been completed for this incident.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On March 22, 2023, two shallow Type II monitoring wells (MW-11R and MW-12) and two deep Type II
monitoring wells (DMW-21 and DMW-27) were gauged, purged, and sampled in accordance with the
NCDEQ guidelines. Free product was not observed during the March 2023 gauging event. Depths to
ground water in the shallow Type II monitoring wells ranged from 7.02 feet to 7.17 feet. Depths to ground

Ground water samples collected from the monitoring wells were submitted for laboratory analyses using
EPA Method 602. The concentrations of benzene, toluene, ethylbenzene, xylenes, MTBE, and/or
naphthalene reported in the ground water samples collected from MW-11R, MW-12, DMW-21, and
DMW-27 were above MACs as specified in T15A NCAC 2L.0202. All the reported contaminant
concentrations were below the GCLs. A summary of the analytical results for ground water samples
collected on March 22, 2023, is presented in Table 6. A Ground Water Quality Map based on the March
2023 data is included as Figure 5. A complete report of laboratory analyses of the ground water samples

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE and
naphthalene concentrations from the February 2008 ground water sampling event, as well as the
maximum historical water column height observed in each area. A theoretical contaminant mass area
was calculated around MW-11R and MW-12 and used in the contaminant mass calculations. The
contaminant mass decreased by 57% between February 2008 and March 2023. Contaminant mass
calculations have been included as Appendix C. A map of the contaminant mass area has been included
as Figure 6. A chart depicting the overall trend in contaminant mass is shown below:

The site is located in the Coastal Plain Physiographic Province of North Carolina. The water table has a
seasonal high depth to water of approximately 2 to 20 feet below ground surface (bgs).
3.0 FREE PRODUCT REMOVAL
Free product has been observed at the site in the past in MW-11R and MW-12. Five MMPE events have
been conducted at the site between June 2012 and February 2015. Approximately 60.96 gallons of vapor
phase free product have been removed from the site. Free product has not been observed at the site
since August 2012.
4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
MMPE events were conducted at the site as the primary method of corrective action at the site. No
natural attenuation monitoring plan is currently in place at the site. Field parameters were collected
during the March 2023 sampling event and presented in Table 7.
5.0 CONCLUSIONS
 On March 22, 2023, two shallow Type II monitoring wells and two deep Type II monitoring wells
were gauged, purged, and sampled. Free product was not observed.

Dear Rae Brown:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/23/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love Project Manager

Notes:
• FP: Free Product
• Area of the contaminant plume is calculated from Figure 6
• Height of the water column is calculated by subtracting the average depth to water from the average well depth of the referenced monitoring wells
• Volume of the contaminant plume is calculated by multiplying the area of the plume by the average height of the water column during each sampling event
• Effective porosity is assumed based on the sub-surface soil profile obtained from well construction records and soil boring logs
• Total mass was calculated by multiplying the total contaminant concentrations for the sampling event with effective volume
• Contaminant mass cannot be calculated in wells containing FP; therefore, the total contaminant mass is based on the known concentrations in the area for each sampling event.
• When areas couldn’t be sampled, the last known concentrations were used in the calculations.
