2.0 EXECUTIVE SUMMARY
The Little Cubbard site is located at 137 US Highway 64, Rutherfordton, Rutherford
County, North Carolina. Seven underground storage tanks (USTs) were previously
operated at the site. Four USTs (one 2,000-gallon gasoline, one 1,000-gallon gasoline, one 2,000-gallon diesel, and one 450-gallon heating oil) were removed from the site in 1993. A petroleum release was discovered during tank closure activities. No potential receptors have been identified within 1,500 feet of the
release.
The purpose of this report is to document the latest monitoring well installation and groundwater sampling event. On July 26, 2023, CATLIN Engineers and Scientists (CATLIN) personnel advanced one boring for the construction of a Type II
monitoring well (MW-15) to 35 feet below land surface (BLS).
On August 9, 2023, CATLIN personnel returned to the site and measured groundwater at approximately 27.5 feet deep across the site. Groundwater samples from five wells (MW-1, MW-2, MW-4, MW-14, and MW-15) were collected. The
samples were submitted for laboratory analysis of volatile organic compounds
(VOCs) per Standard Method (SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE), and diisopropyl ether (DIPE).
Laboratory results indicted multiple dissolved petroleum constituents at
concentrations greater than those established in Title 15A of the North Carolina
Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS) in all monitoring well samples. Benzene was also above its GCL in three samples (MW-1, MW-4, and MW-14), and MTBE was above GCL in the MW-1 and MW-14 samples.
Contaminant concentrations have generally increased since the previous sampling event (May 2023) and petroleum constituent concentrations persist above GCL at the site.
CATLIN recommends conducting a high-resolution site characterization (HRSC)
event at the site to help determine the vertical and lateral extent of contamination and to provide the necessary information for a possible future in-situ remediation.
3.0 SCOPE OF SERVICES
The scope of services for this report was performed in general accordance with CATLIN proposal number 221064.01P, dated July 6, 2023. Services were authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s) Task Authorization (TA) #01, accepted on July 21, 2023, and Contract Number
N70522-A.
The approved scope of services for this Task Authorization included:
•Install one Type II monitoring well (MW-15) up to 35 feet BLS;
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 3 September 2023
•Survey the top of casing (TOC) elevation of the new well relative to anexisting well;
•Collect groundwater samples from MW-1, MW-2, MW-4, MW-14, andMW-15;
•Analyze six water samples (five groundwater samples and one field blank)
according to SM 6200B (including EDB, MTBE, and DIPE); and
•Prepare and submit a monitoring report summarizing the findings.
The scope of services was conducted in accordance with the approved TA.
4.0 SITE HISTORY AND CHARACTERIZATION
The Little Cubbard site is located at 137 US Highway 64, Rutherfordton, Rutherford County, North Carolina (Figures 1 and 2). Summarized available historical sampling
and gauging data from previous consultants are provided in Appendix A. Recent site
photographs are presented in Appendix B.
4.1 UST OWNER AND OPERATOR INFORMATION
Ray Thomas Petroleum Company, Inc. (Thomas Petroleum), owned the
USTs historically operated on-site. Thomas Petroleum filed for Chapter 11 Bankruptcy in 2013. The site was subsequently accepted in into the North Carolina UST Section Trust Fund Branch State Lead Program (NCDEQ, 2015).
Available information regarding UST owners/operators and is presented in Table 1.
4.2 UST INFORMATION
Limited historical files available on the NCDEQ Waste Management Online Database (aka Laserfiche) present conflicting information regarding the former USTs. According to NCDEQ Department of Waste Management (DWM) memo (2015) and the NCDEQ Tanks Database, up to seven USTs
were previously operated at the site. However, reports prepared by ECS
Southeast, LLP (ECS) and the GW/UST-2 Form completed by Bruce Bridges of Quality Petroleum Installation Service and submitted after UST removal only reference four USTs (ECS, 2020; Bridges, 1993).
The GW/UST-2 form indicates that one 2,000-gallon gasoline UST, one
1,000-gallon gasoline UST, one 2,000 gallon-diesel UST, and one 450-gallon heating oil UST were removed from the site in 1993 (Bridges, 1993). It is likely that additional USTs were historically operated at the site, however their capacity, previous contents, and operation dates are unknown.
Reportedly, all USTs have been removed from the site (ECS, 2019).
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 4 September 2023
Available UST system information is presented in Table 1 and the approximate former UST system locations are shown on Figure 3.
4.3 CONTAMINANT SOURCE INVENTORY
An on-site release was discovered in 1993 during tank closure activities. According to NCDEQ records, elevated concentrations of benzene, toluene, ethylbenzene, and total xylenes (BTEX) compounds were detected in soil
samples collected from beneath the former diesel and gasoline USTs
(NCDEQ, 2015). A site history summary is included in Appendix A.
4.4 SITE CHARACTERISTICS
The property is owned by Timothy and Lois Mace. The site has been razed and the former structures are no longer present. It appears to be used for part-time storage of piping associated with ongoing construction projects.

Site photographs are presented in Appendix B. 4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE

Properties in the site vicinity are mostly residences and businesses. Residences are located to the north, west, and east of the site. The Thermal Belt Rail-Trail is located across Long Street, west of the site. A construction field office is located to the northeast, across US Highway 64 from the site.
4.6 RECEPTOR INFORMATION Conducting a receptor survey was outside the scope of this monitoring event. A review of historical files available on Laserfiche indicates that the last
receptor survey update for the Little Cubbard site was conducted in 2020 by
ECS. According to previous reports, municipal water is available to the site vicinity. ECS did not identify any receptors within 500 feet of the site but did indicate
there is potential that some properties located near the site utilize water
supply wells. No surface water bodies were identified within 1,500 feet of the site.
Potential receptors are illustrated on Figure 2 and receptor information
obtained from ECS (2020) is shown in Table 2.

4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES
The release was discovered in 1993 during UST closure activities. Historical
files available on Laserfiche do not fully elucidate the site history. However,
according to the site history presented in a State Lead Referral Memo prepared by NCDEQ personnel, 120 cubic yards of contaminated soil were removed with the USTs in 1993. Elevated concentrations of BTEX compounds were reported in soil samples collected from beneath the
gasoline and diesel USTs (NCDEQ, 2015).
Between 1993 and 1994, 13 Type II monitoring wells (MW-1 through MW-13) were installed during Comprehensive Site Assessment (CSA) activities. Several VOCs were reported above their respective 2L GWQS in samples
collected from multiple wells during the CSA. LNAPL was measured in
monitoring well MW-4. A soil sample collected during monitoring well installation reportedly contained elevated concentrations of Total Petroleum Hydrocarbons (TPH) (NCDEQ, 2015).
Following the CSA, 0.45 gallons of LNAPL were recovered from MW-4 in
February 1994 and a Corrective Action Plan (CAP) was submitted by CBM Environmental (CBM) in November 1994. The CAP reportedly recommended LNAPL and impacted soil removal, and to remediate groundwater by conducting groundwater recovery and treatment with soil-venting on-site. The
CAP-proposed remedial actions were reportedly initated by July 20, 1996
and deep well TW-1 was installed by 2002 (NCDEQ, 2015).
Regular groundwater monitoring and LNAPL recovery events have been conducted at the site since 1994. LNAPL has previously been measured in
monitoring wells MW-1, MW-4, and TW-1. It is unclear how LNAPL was
historically recovered from the wells and the total amount of LNAPL removed is unknown (NCDEQ, 2015). In 2019, ECS conducted an Aggressive Fluid Vapor Recovery (AFVR) event, using MW-4 as an extraction point. During the AFVR event, a calculated total of 0.0610 pounds of VOCs were emitted
as vapor and approximately 278 gallons of petroleum-impacted groundwater
was recovered (ECS, 2019).
Groundwater samples previously obtained from monitoring wells MW-1, MW-4, MW-7, and TW-1 have reportedly contained petroleum constituents at
concentrations above their respective GCL. Since 1995, the BTEX compound
concentrations have generally decreased in samples obtained from on-site monitoring wells. During monitoring events conducted in 2019, groundwater samples were obtained from MW-1, MW-2, MW-3, MW-4, MW-6, MW-7, MW-9, MW-11, and TW-1. Laboratory analytical results revealed multiple
petroleum constituents at concentrations above their 2L GWQS in samples
from MW-1, MW-4, MW-6, MW-7, MW-9, and TW-1. Benzene was reported above its GCL in the samples collected from MW-1 and MW-4 in 2019 (ECS, 2020).
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 6 September 2023
In 2020, Provectus ORS sleeve (ORS) remedial devices were deployed in monitoring wells MW-1 and MW-4. However, groundwater samples were not obtained six months after deployment (as recommended) to determine the
efficacy of the ORS devices (ECS, 2020).
CATLIN conducted a groundwater monitoring event in June 2021. During the site visit, TW-1 was observed as destroyed, MW-6 was obstructed, and wells MW-3 and MW-7 could not be located and were presumed destroyed. The
remaining monitoring wells were gauged and sampled. Laboratory results
revealed multiple contaminants in the samples from MW-1, MW-2, and MW-4 at concentrations above 2L GWQS. Benzene and MTBE were above their respective GCL in the sample from MW-1, and benzene was above GCL in the MW-4 sample. No measurable thickness of LNAPL was present in any of
the monitoring wells (CATLIN, 2021).
In November 2022, CATLIN supervised a MMPE event by AES utilizing monitoring wells MW-1 and MW-4. Prior to the event, LNAPL was measured in both MW-1 (0.02 feet thick) and MW-4 (0.25 feet thick). A total of 2,010
gallons of impacted groundwater and LNAPL were removed and
approximately 2,699.07 pounds of petroleum vapors were emitted (equivalent to 438.73 gallons of petroleum). CATLIN returned to the site in December 2022 to gauge and sample MW-1 and MW-4. There was no measurable thickness of LNAPL in the wells. Several petroleum constituents were
reported at concentrations above 2L GWQS in both samples. Benzene, EDB,
and MTBE were above their respective GCL in the sample from MW-1, and benzene was above GCL in the MW-4 sample (CATLIN, 2023A).
CATLIN installed a 4-inch diameter recovery well (MW-14) in March 2023,
and later that month partnered with AES to conduct another MMPE event
utilizing MW-1, MW-4, and MW-14. No LNAPL was detected before or following the event. A total of 890 gallons of impacted groundwater were removed and approximately 523.17 pounds of petroleum vapors were emitted (equivalent to 85.04 gallons of petroleum). CATLIN returned to
conduct a sampling event in May 2023. Groundwater samples were collected
from MW-1, MW-4, and MW-14. Multiple petroleum constituents were detected at concentrations above 2L GWQS in all three samples. Benzene was also above its GCL in all samples, and MTBE was above GCL in the MW-1 and MW-14 samples (CATLIN, 2023B).
Summarized historical data from ECS (2020) and a detailed site history prepared by NCDEQ personnel are presented in Appendix A.
5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY
5.1 SOIL AND BEDROCK
As defined in the Geologic Map of North Carolina, published by the North Carolina Department of Natural Resources and Community Development
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 7 September 2023
(1985), the site lies within the Piedmont physiographic province. The site is underlain by interlayered hornblende gneiss, metagabbro, mica schist, and granitic rock of the Inner Piedmont belt.
The boring log from recovery well installation (MW-15) during this monitoring period indicates that clayey silt is present to approximately 22 feet BLS. Sandy silt was encountered from approximately 22 to 32 feet BLS. Silty clay was observed at depths up to 35 feet BLS.
5.2 HYDROGEOLOGY
Groundwater - The 2020 Visual Hydrogeologic Framework – North Carolina Hydrogeological Database did not identify sufficient boreholes near the site to
draw a cross-section. Sandy clay was recently encountered in the surficial
aquifer.
Surface Water – ECS (2020) did not identify any surface water bodies within 1,500 feet of the site during the most recent receptor survey.
6.0 SITE ASSESSMENT INFORMATION
CATLIN conducted field activities in general accordance with the approved TA. Field activities included monitoring well (MW-15) installation and groundwater sampling.
Upon arrival at the site, potential hazards were evaluated before beginning field
work and their discussion is documented on Daily Activities Logs, included in Appendix C. Photographs from the site visits are included in Appendix B. Well locations and site features are shown on Figure 3 and well construction details are presented in Table 3.
6.1 MONITORING WELL INSTALLATION
On July 26, 2023, a boring was advanced to 35 feet BLS for monitoring well construction by a North Carolina Certified Well Contractor, utilizing hollow
stem augers and a CME 55D drill rig. Cuttings generated during drilling activities were spread on-site.
The well (MW-15) was constructed of new, threaded PVC casing and screen. No glues or cements were used in joining PVC components. New nitrile
gloves were worn while handling all well materials. The monitoring well was constructed with a pointed PVC sediment trap, approximately 20 feet of 2-inch diameter, 0.010-inch slotted PVC well screen and 15 feet of 2-inch diameter solid PVC riser to the surface. The annular space was filled with coarse sand pack to approximately two feet above the well screen and
bentonite chips to within one foot of the ground surface. The bentonite chips were poured from the surface while simultaneously pouring water to facilitate hydration. The well was finished with a locking well cap, a flush-mount steel wellhead, and a concrete pad. The TOC elevation was measured using
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 8 September 2023
traditional survey methods (Rod and Level) in relation to a preexisting monitoring well (MW-1).
Monitoring well construction information is summarized in Table 3 and a site
map with monitoring well location is illustrated on Figure 3. Site photographs are presented in Appendix B. The well log and Well Construction Record were submitted to NCDEQ, Division of Water Quality and copies are provided in Appendix D.
6.2 GAUGING DATA
Historically, depth to groundwater in the shallow wells has ranged from 4.75 feet below top of casing (BTOC) (MW-10) to 29.71 feet BTOC (MW-11).
Depth to groundwater in the deep well (TW-1) had ranged from 21.50 feet
BTOC to 36.77 feet BTOC (ECS, 2020).
During the August 2023 event, CATLIN personnel measured depth to water using an electronic water interface probe. To prevent cross contamination,
the probe and cabling were decontaminated according to the manufacturer’s
recommendations between use in each well. Gauging data were recorded on an electronic groundwater sampling form using a tablet device. Gauging procedures were performed in general accordance with North Carolina Department of Environmental and Natural Resources (NCDENR) and
NCDEQ Guidelines, and Environmental Protection Agency (EPA) Region 4
Operating Procedures.
Depth to water ranged from 24.48 feet BTOC (MW-4) to 28.74 feet BTOC (MW-15). Based on groundwater elevations calculated for this monitoring
period, groundwater flow direction is towards the east.
Monitoring well gauging results for events conducted by CATLIN are presented in Table 3. Groundwater elevations and flow direction are illustrated on Figure 4 and groundwater sampling forms are provided in
Appendix C.
6.3 SAMPLING DATA
Following gauging, the wells were sampled in general accordance with
NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating Procedures.
Prior to obtaining representative groundwater samples, each monitoring well was purged by removing a minimum of three well volumes using a new, disposable bailer. Monitoring well MW-15 was not developed after installation, so it was bailed dry several times and allowed to recover prior to
sampling. Groundwater field parameter data were measured at one-minute intervals using an In-Situ Aqua Troll 600 Multiparameter Sonde (Aqua Troll). Conductivity, dissolved oxygen, and temperature measurements were recorded utilizing the VuSitu mobile application (version 1.17.12). Groundwater parameter data were transferred from the VuSitu mobile
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 9 September 2023
application to the electronic groundwater sampling forms. Several of the wells did not yield sufficient water to obtain VuSitu readings, which is noted on the sampling forms. Copies of the groundwater sampling forms are available in
Appendix C.
After a minimum of three well volumes were removed (or the well was bailed dry), a groundwater sample was collected from each well and poured into appropriate laboratory-provided, pre-preserved glassware, labeled, and
placed on ice in an insulated cooler. A field blank was collected by pouring
distilled water from a new gallon jug into appropriate laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler.
The groundwater samples and field blank were submitted to Con-Test
Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East
Longmeadow, Massachusetts, under proper chain of custody (COC) protocol for analyses described in Section 3.0 Scope of Services. The COC is included with the analytical report provided Appendix E.
6.4 SUMMARY OF GROUNDWATER INFORMATION
Historically, samples from monitoring wells MW-1 and MW-4 have contained the highest petroleum constituent concentrations. During the previous sampling event (May 2023), monitoring wells MW-1 and MW-4 contained
several VOCs at concentrations above their 2L GWQS. Benzene was
reported above GCL in the MW-1, MW-4 and MW-14 samples, and MTBE was above GCL in the samples from MW-1 and MW-14. LNAPL has been previously detected in MW-1, MW-4, and TW-1; however, it has not been reported since November 2022. Historical information prepared by other
consultants is included in Appendix A.
The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Historical results for events conducted by CATLIN are included in Table 5. Monitoring well sample analytical results are
illustrated on Figure 5. A copy of the complete laboratory report and COC
documentation are in Appendix E.
Monitoring Wells
During the August 2023 monitoring event, five groundwater samples (MW-1,
MW-2, MW-4, MW-14, and MW-15) were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above their respective reporting limits in the samples from MW-15. Benzene was reported above its GCL in the
MW-1, MW-4, and MW-14 samples, and MTBE was also above its GCL in
the MW-1 and MW-14 samples. Analytical results reported the following constituents at concentrations above their 2L GWQS in the samples from MW-1, MW-2, MW-4, and MW-14:
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 10 September 2023
•MW-1: benzene (GCL exceedance), DIPE, ethylbenzene,isopropylbenzene, MTBE (GCL exceedance), naphthalene, n-
propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-
trimethylbenzene, and total xylenes;
•MW-2: benzene and MTBE;
•MW-4: benzene (GCL exceedance), n-butylbenzene, ethylbenzene,MTBE, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,4-trimethylbenzene, and total xylenes; and
•MW-14: benzene (GCL exceedance), DIPE, ethylbenzene,
isopropylbenzene, MTBE (GCL exceedance), naphthalene, n-
propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes.
Field Blank
One field blank sample was submitted for analysis per SM 6200B (including EDB, MTBE, and DIPE). An estimated (“J”-value) concentration of acetone, a known laboratory artifact, was detected in the field blank sample. No other targeted analytes were detected.
6.5 EVALUATION OF ASSESSMENT INFORMATION
Extent of Contamination
Several petroleum constituents were detected above their respective 2L
GWQS in samples from MW-1, MW-2, MW-4, and MW-14. Samples from MW-1 and MW-14 contained concentrations of benzene and MTBE above their respective GCL. The MW-4 sample also revealed benzene above its GCL. A summary of monitoring well groundwater sample analytical results
are illustrated on Figure 5.
The highest petroleum constituent concentrations have historically been reported in samples from MW-1 and MW-4. Laboratory analysis for samples collected during this event indicate benzene and/or MTBE remain above GCL
in samples from MW-1, MW-4, and MW-14, and overall VOC concentrations
have generally increased since the previous event (CATLIN, 2023A).
Cleanup Levels Achieved
Soil – In October 1993, approximately 120 cubic yards of impacted soil were
removed from the site. Soil samples obtained from beneath the former USTs and MW-1 boring contained elevated BTEX and TPH concentrations (NCDEQ, 2015).
Groundwater – Groundwater contaminant concentrations are above 2L
GWQS at the site and benzene and MTBE were reported above GCL.
NCDEQ; 10873_Little Cubbard CATLIN Engineers and Scientists
CATLIN Project No. 221064 11 September 2023
LNAPL – LNAPL was not measured during this monitoring period. LNAPL has been measured at the site since 1994. However, LNAPL has not been detected since November 2022.
7.0 CONCLUSIONS AND RECOMMENDATIONS
Conclusions
Site activities for this period are summarized below:
•One Type II monitoring well (MW-15) was installed to 35 feet BLS.
•Groundwater samples were collected from five monitoring wells (MW-1,
MW-2, MW-4, MW-14, and MW-15) and submitted for analysis per SM6200B (including EDB, MTBE, and DIPE).
•Multiple VOCs were detected above 2L GWQS in the MW-1, MW-2, MW-4,and MW-14 samples.
•No VOCs were detected about the laboratory reporting limit in the samplefrom MW-15.
•Benzene and MTBE were detected above their GCL in the MW-1 and MW-14
samples. Benzene was also detected above its GCL in the MW-4 sample.
•LNAPL was not measured during this monitoring event.
•The petroleum constituent concentrations in the monitoring well samples
have generally increased since May 2023 and VOC concentrations persist
above GCL.
Recommendations
CATLIN recommends conducting a HRSC event at the site to help determine the
vertical and lateral extent of contamination and to provide the necessary information for a possible future in-situ remediation.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method 6200B elevated reporting limits for samples 23H1987-01,02,03+04 due to high concentrations of target compounds.
[TOC_1]Case Narrative[TOC]
SM21-23 6200B
Qualifications:

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Elevated reporting limit due to high concentration of target compounds.RL-11
