◼ Petroleum constituents were not detected above GCLs during this sampling event. Prior detections
above GCLs included benzene detections in well MW-3 in January 2012 and well MW-5 in January
2018.
◼ The monitoring wells did not contain measurable thicknesses of free product. Free product
thicknesses have not been measured in the monitoring wells since May 2012 (MW-5).
◼ The groundwater contaminant plume appears to be relatively stable and is generally delineated
horizontally with the exception of the southwestern extent. The contaminant plume is not vertically
delineated; however, active potable wells are not located within 500 feet of the source area.
Groundwater impacts extend off-site to the southwest.
◼ Seven potable water supply wells were identified within 1,000 feet of the source area. The
majority of these wells are located to the north and east of the site and are topographically cross-
to up-gradient in relation to the plume. These wells are located over 600 feet from the source
area. Municipal water is reportedly available to the site and properties located within 1,000 feet
of the source area.
◼ Based on the Interstate Technology and Regulatory Council (ITRC) Petroleum Vapor Intrusion
(PVI) guidance, additional evaluation of the PVI pathway is warranted due to a depth to water of less
than five feet below land surface (ft bls), concentrations above Residential Vapor Intrusion –
Groundwater Screening Levels (VI-GWSLs), and the historical presence of ethylene dibromide
(EDB), a precluding factor.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to present the findings of assessment activities performed on
March 4, 2019 at the Blalock Fina site located at 3574 NC Highway 55 in Angier, Harnett County,
North Carolina (Figure 1). This Subsequent Monitoring report was prepared for the site based on
Terracon’s proposal, as approved by Mr. Mark Petermann, Project Manager with the NCDEQ
Division of Waste Management, State Lead Program.

The Subsequent Monitoring Report was prepared in general accordance with the 15A NCAC 2L
.0115 regulations and the NCDEQ UST Section Guidelines for Assessment and Corrective Action for
UST Releases, dated July 15, 2008, revised December 2313, under the supervision of
Mr. William O. Frazier, a North Carolina registered professional geologist (North Carolina License
No. 2576).
C.1 Site Setting
The Blalock Fina site is comprised of 0.69 acres and consists of vacant, predominantly cleared land.
The surrounding properties consist of residential properties to the west, south, and east with
agricultural land to the north. The site and surrounding properties are depicted on Figures 2 and 3.

C.2 Release Summary
A petroleum release was discovered in February 2001, when laboratory analysis of soil samples
collected following the removal of the former on-site USTs revealed the presence of petroleum
contaminants. A chronological summary of UST removal and subsequent assessment activities at
the site is discussed in the following section of the report.
C.3 Previous Investigations
The site was reportedly operated as a gasoline station and convenience store beginning in 1957.
The site reportedly originally operated two 1,000-gallon gasoline USTs with a third 550-gallon
gasoline UST added to the site in 1958. Approximately 1,224 tons of contaminated soil was
excavated during the UST removal activities in February 2001. Investigation activities conducted
between 2002 and the present included installation of twelve monitoring wells, two recovery wells,
and two vapor extraction wells, water supply well sampling, a mobile multi-phase extraction (MMPE)
event in 2004, and an injection event in July 2011.

The injection event in July 2011 utilized chemical oxidation and oxygen releasing compounds. The
injectate consisted of a solution of 18% persulfate and 2% PermOx Plus into two separate areas at
the site including the former source area on the north side of NC Highway 55 and a down-gradient
area south of NC Highway 55 (Figure 2). During the injection, vacuum extraction was applied to
vapor extraction wells and multiple monitoring wells to remove contaminant mass, prevent
groundwater mounding and provide hydraulic control. The results of the injection and other
investigation activities were used to generate a conceptual site model of current conditions, which is
included as Table 1.

Terracon completed a New Technology Cleanup Report (Terracon, 2015b), which reviewed several
industry-accepted remedial approaches. Due to its versatility to be utilized effectively in both aerobic
and anaerobic environments, the lack of need for permanent on-site infrastructure, and the ability to
avoid engineering concerns associated with the highway, Terracon recommended enhanced
bioremediation via injections of BOS 200® with a proposed injection event preceded by a sampling
event to provide baseline, pre-injection groundwater data.

NCDEQ filed a Notice of Residual Petroleum (NRP) for soil and groundwater on December 9, 2016
prior to the sale of the property between Mr. Blalock and a new property owner. The NRP is filed with
the deed in Book 3462, Page 818-820.
C.4 Water Supply Wells
Terracon conducted an updated receptor survey consisting of a windshield reconnaissance from
publicly-accessible rights-of-way of the properties located within 1,500 feet of the site. In addition,
Terracon contacted Harnett Regional Water, which provided information regarding whether water
service has been established at these properties. Water supply wells were identified visually during
Blalock Fina
Angier, North Carolina
Terracon Project No. 70149672A
Incident No. 24238
December 23, 2019

Responsive ■ Resourceful ■ Reliable 5
the reconnaissance and/or by review of information provided by Harnett Regional Water. If a
developed property was listed as not having water service, Terracon assumed that a potable water
supply well is in use at that property. If a water supply well was observed at a property that was listed
as having water service, Terracon assumed that the water supply well is non-potable.

Thirteen water supply wells were identified within 1,000 feet of the source area. At that time, seven
of the thirteen wells appear to serve as active, potable water sources within 1,000 feet of the source
area. These wells are generally situated topographically cross- to up-gradient of the plume. The most
proximate potable water supply well is WSW-5, which is located approximately 625 feet east and
cross-gradient of the source area. Down-gradient water supply wells are reportedly either inactive or
non-potable. Municipal water is reportedly available to the site and surrounding properties located
within 1,000 feet of the source area.

Results of the water-supply well inventory are presented in Table 2 and well locations are depicted
on Figure 3.
D. ASSESSMENT INFORMATION

Terracon mobilized to the site on October 18 and 23, 2019 to oversee the installation of, develop,
and sample new monitoring well MW-12 as well as sample the existing fourteen monitoring wells
(MW-1, MW-3 through MW-11, RW-1, RW-2, VEW-1, and VEW-2) for analysis of volatile organic
compounds. Terracon also oversaw the repair of the well pads and manway covers of MW-1 and
MW-10. The approximate locations of the wells are shown on the Site Plan (Figure 2).
D.1 Monitoring Well Installation Activities

On October 18, 2019, Terracon oversaw the installation of monitoring well MW-12. The monitoring
well was constructed as follows:

◼ Installation of two-inch diameter, 0.010-inch machine slotted PVC 10 foot well screen with a
threaded bottom cap;
◼ Installation of two-inch diameter, threaded, flush-joint PVC riser pipe to surface;
◼ Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the well screen
from the bottom of the boring to approximately 0.5 feet above the top of the well screen;
◼ Addition of approximately 0.5 feet of hydrated bentonite chips on top of the sand pack;
◼ Grout remaining annulus above the bentonite seal to the land surface; and
◼ Installation of a flush mount protective cover in a two-foot by two-foot concrete pad.

Terracon surveyed the top of casing of MW-12 relative to existing monitoring wells. The well
construction details are included on Table 3, and the construction record is included in Appendix A.
Following installation of MW-1R, the well was developed using a submersible pump. During well
development, approximately 5 casing volumes were removed from the well.

D.2 Sampling Activities
D.2.1 Free Product Evaluation
Free product was not encountered in the monitoring wells during this assessment.
D.2.2 Groundwater Sampling Activities

Prior to sample collection, Terracon gauged the depth to groundwater in the monitoring wells.
Current and historical groundwater elevation measurements are provided in Table 3. The surficial
groundwater flow direction was estimated to the southwest based on the calculated groundwater
elevations. Groundwater elevations for the most recent sampling event are depicted on Figure 4.
Photographs and copies of field notes are provided in Appendix B.

Prior to sampling, the wells were purged with a peristaltic pump using low flow sampling techniques
(i.e., <200 milliliters per minute) prior to sampling. Field parameters consisting of pH, temperature,
oxidation-reduction potential (ORP), dissolved oxygen, and conductivity were measured at each of
the well locations. After stabilization of pH and conductivity, a groundwater sample was collected
directly into laboratory supplied containers at low flow sampling rates.

The groundwater samples were placed in laboratory-supplied glassware, labeled and stored in an
ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to
Shealy Environmental Services, Inc., in West Columbia, South Carolina for analysis of VOCs by EPA
Method 6200B including methyl tert-butyl ether (MTBE), ethylene dibromide (EDB) and di-isopropyl
ether (IPE).
D.2.3 Groundwater Analytical Results
Based on the laboratory analytical reports, petroleum constituents were identified at concentrations
above 2L standards in monitoring wells MW-1, MW-3, MW-5, MW-6, MW-11, RW-1, RW-2, VEW-1,
and VEW-2. Petroleum constituents were not present at concentrations above GCLs. Benzene
exceeded its GCL in MW-3 in January 2012 and in MW-5 in January 2018.

Petroleum constituents were not present at concentrations above 2L standards in the remaining
wells. Groundwater detections are depicted on Figure 5 and summarized on Table 4. Analytes were
not detected above laboratory reporting limits in the field blank (FB-01). Copies of the laboratory
analytical reports are provided in Appendix C. Isoconcentration maps for benzene and naphthalene
are included on Figures 6 and 7, respectively. These maps show the contaminant plumes generally
originating from the south-central portion of the site in the source area and migrating to the
west-southwest underneath NC Highway 55 and onto the adjacent southwestern property.

The groundwater contaminant plume appears to be relatively stable and is generally delineated
horizontally with the exception of the southwestern extent. The extent of groundwater impact is not
vertically delineated; however, active potable wells are not located within 500 feet of the source area.

EDB (a lead scavenger compound) was not detected during this event but has been previously
detected above its 2L standard. The historical detections indicate that the fuel type released at the
site was gasoline containing a lead scavenger. According to the ITRC PVI guidance, this fuel type is
a precluding factor; therefore, the ITRC screening process using screening distances cannot be
used.

As a first step of assessment in accordance with the ITRC guidance, Terracon implemented a
concentration-based evaluation by comparing groundwater concentrations with the NCDEQ
Residential and Non-Residential VI-GWSLs. Concentrations in MW-1, MW-3, MW-5, MW-6, VEW-1,
VEW-2, RW-1, and/or RW-2 were detected above the Non-Residential VI-GWSLs for benzene,
ethylbenzene, naphthalene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and/or total xylenes
during the October 2019 sampling event.

Based on the historical presence of EDB as a lead scavenger compound, the present water quality
conditions, and shallow water table, additional PVI assessment appears necessary.
E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of soil, surface water, and groundwater testing
activities, Terracon provides the following findings and conclusions:

◼ Monitoring well MW-12 was installed to a total depth of 14 feet below land surface (bls) with a screen
interval from 4 to 14 feet bls.
◼ Petroleum constituents were detected at concentrations above their respective 15A NCAC 2L
Groundwater Quality Standards (2L standards) in wells MW-1, MW-3, MW-5, MW-6, MW-11, RW-1,
RW-2, VEW-1, and VEW-2.
◼ Petroleum constituents were not detected above GCLs during this sampling event. Prior detections
above GCLs included benzene detections in well MW-3 in January 2012 and well MW-5 in January
2018.
◼ The monitoring wells did not contain measurable thicknesses of free product. Free product
thicknesses have not been measured in the monitoring wells since May 2012 (MW-5).
◼ The groundwater contaminant plume appears to be relatively stable and is generally delineated
horizontally with the exception of the southwestern extent. The contaminant plume is not vertically
delineated; however, active potable wells are not located within 500 feet of the source area.
Groundwater impacts extend off-site to the southwest.
◼ Seven potable water supply wells were identified within 1,000 feet of the source area. The
majority of these wells are located to the north and east of the site and are topographically cross-

to up-gradient in relation to the plume. These wells are located over 600 feet from the source
area. Municipal water is reportedly available to the site and properties located within 1,000 feet
of the source area.
◼ Based on the ITRC PVI guidance, additional evaluation of the PVI pathway is warranted due to a
depth to water of less than five feet below land surface (ft bls), concentrations above Residential VI-
GWSLs, and the historical presence of EDB, a precluding factor.
Based on the data presented in this Subsequent Monitoring report, Terracon recommends the
following activities be completed at the site.

◼ Conduct semi-annual groundwater monitoring events.
◼ Complete a vapor intrusion evaluation based on the presence of a precluding factor according to the
ITRC guidance and the presence of petroleum concentrations in groundwater above Non-Residential
VI-GWSLs.
◼ Based on Terracon’s New Technology Cleanup Report (Terracon, 2015b), which reviewed several
industry-accepted remedial approaches, Terracon recommended enhanced bioremediation via
injections of BOS 200®. Based on funding availability and future site redevelopment, some level of the
BOS 200® injections should be implemented. If alternative technologies are not preferred, monitoring
natural attenuation should continue for the site on a semi-annual basis.
