Groundwater Monitoring Report
NC DOT Maintenance Facility
Robbinsville, North Carolina
H&H Job No. DOT-476

1.0 Introduction

This monitoring report documents groundwater sampling performed at the North Carolina
Department of Transportation (NC DOT) maintenance facility located at 40 State Shed Road in
Robbinsville, Graham County, North Carolina (Site). Due to failing cathodic protection
monitoring tests, a 5,700-gallon gasoline underground storage tank (UST) and a 5,700-gallon
diesel UST were removed from the Site by NC DOT on August 31, 2004. During excavation
activities, the diesel product line leading to the dispenser island was broken and approximately
1,000-gallons of diesel fuel was released in the UST basin area. Approximately 3,900-gallons of
product and water were pumped from the UST basin. A Site location map is provided as Figure
1, and a Site map is included as Figure 2.

Due to the presence of a surface water (Tulula Creek) within 500 ft of the site and previously
detected concentrations of petroleum constituents in groundwater that exceed 10 times the 2B
Surface Water Standards, the North Carolina Department of Environmental Quality (NC DEQ)
risk classification for this incident is Intermediate (95D). The DEQ incident number is #28254.

The environmental assessment work described in this report was conducted for NC DOT and
included the following tasks:
 Conducting receptor survey update activities within a 1,500 ft radius of the source area
 Locating and gauging all monitoring wells
 Sampling on-site monitoring wells MW-1 through MW-5 and DW-1
 Data Evaluation and Reporting

2.0 Site History

Due to failing cathodic protection monitoring tests, a 5,700-gallon gasoline UST and a 5,700-
gallon diesel UST were removed from the Site by NC DOT on August 31, 2004. During
excavation activities on August 26, 2004, the diesel product line leading to the dispenser island
was broken and approximately 1,000-gallons of diesel fuel was released. Approximately 3,900-
gallons of product and water were pumped from the UST basin using two 4-inch diameter basin
wells.

Nine soil samples (SS-1 through SS-9) were collected by NC DOT from the excavation sidewalls
and adjacent to the dispenser line and dispensers after UST removal activities on August 31,
2004. Due to the presence of shallow groundwater, soil samples were collected at depths ranging
from 2.5 ft to 4 ft below ground surface (bgs). Bedrock was encountered in the former UST basin
at a depth of approximately 12 ft bgs. Petroleum-related constituents were detected in UST
closure soil samples above Soil to Water and/or Residential Maximum Soil Contaminant
Concentrations (MSCCs). Petroleum-related constituents were also reportedly detected in a
groundwater sample collected from the UST basin.

Based on the results of UST closure activities, Limited Site Assessment (LSA) activities were
conducted at the site by H&H in 2005. Five Type II monitoring wells (MW-1 through MW-5)
and one Type III monitoring well (DW-1) were installed at the site during LSA activities.
Concentrations of petroleum constituents above the NC 2L Groundwater Standards were
detected in monitoring wells at the site. As noted above, concentrations of petroleum
constituents detected in groundwater samples collected at the site also exceeded 10 times the 2B
Surface Water Standards.

No water supply wells were identified within a 1,500 ft radius of the site during LSA activities in
2005. However, a named surface water body (Tulula Creek) is located approximately 200 ft
west of the former dispenser area and 250 ft west of the former UST basin area. Tulula Creek is
classified as a Water Supply Class III (WS-III) and a Trout Water (Tr). The Site and
surrounding properties utilize municipal water.

Robbinsville/Report/AS_3030_28254_MRP_20221219_Monitoring Report.doc
In a NC DEQ Notice of Regulatory Requirements letter dated January 19, 2021 and follow up
email request dated June 30, 2022, NC DEQ requested a comprehensive groundwater sampling
event and an updated receptor survey be conducted to evaluate current risks associated with the
site. Based on review of H&H files, limited files provided by NC DOT and NC DEQ, and
discussions between H&H and NC DEQ, no assessment activities had been conducted at the site
since completion of the LSA in 2005. Per NC DEQ’s request, H&H sampled the site monitoring
wells and conducted an updated receptor survey to evaluate current risks associated with the site.
The receptor survey and groundwater sampling activities are described below.

3.0 Receptor Survey Update Activities

No water supply wells were identified within a 1,500 ft radius of the site during LSA activities in
2005. Municipal water is supplied to occupied properties within the site area including the
subject property. H&H identified one surface water body (Tulula Creek) located, adjacent to the
site, approximately 200 ft west of the former dispenser area and 250 ft west of the former UST
basin area. Tulula Creek is classified as a Water Supply Class III (WS-III) and Trout Water (Tr).

On September 8, 2022, H&H conducted a receptor survey update for surrounding properties
within 1,500 ft of the source area at the site. Prior to conducting the survey, H&H contacted the
Town of Robbinsville water department to verify water usage in the area. H&H confirmed that
municipal water is available to properties within a 1,500 ft radius of the site.

As part of the receptor survey update, H&H performed driving and walking reconnaissance of
the site area to look for evidence of water supply wells. H&H also distributed NC DEQ Request
for Water Supply Well Information forms to property owners within a 500 ft radius of the release
area via hand delivery and/or via US Mail. During the receptor survey, H&H spoke with a
neighbor of the property owner at 209 Old Tallulah Road located approximately 900 ft southeast
of the site. The neighbor indicated a water supply well may be located on the 209 Old Tallulah
Road property. H&H hand delivered the Request for Water Supply Well Information form to the
209 Old Tallulah Road address. The form was returned to H&H which indicates two water
supply wells (WS-1 and WS-2) were installed approximately five years ago and provide water to
three residences at 209 and 240 Old Tallulah Road. The wells are also used for livestock. H&H
did not observe the wells during the receptor survey and we were not able to contact the owner to
confirm the well locations. As such, the well locations are estimated at the two property
addresses noted above (see Figure 3).

Only six NC DEQ Request for Water Supply Well Information forms were returned to H&H.
No other water supply wells were identified during the receptor survey activities. Adjacent
property owner and water supply well information is included in Table 1. NC DEQ Request for
Water Supply Well Information forms are included in Appendix A.

4.0 Geology and Hydrogeology

4.1 Regional Geology and Hydrogeology

According to the North Carolina Geological Survey 1985 Geologic Map of North Carolina, the
site area is located in the Blue Ridge Belt of the Blue Ridge Physiographic Province of North
Carolina. According to the geologic map, the basement rocks in the site area are composed of
metasandstone, metagraywacke, metasiltstone, and mica schist.

In the Blue Ridge, bedrock is overlain by a mantle of weathered rock or saprolite. The saprolite
consists of unconsolidated clay, silt, and sand with lesser amounts of rock fragments. Due to the
range of parent rock types and their variable susceptibility to weathering, the saprolite ranges
widely in color, texture, and thickness. Generally, the saprolite is thickest near interstream
divides and thins toward stream beds. In profile, the saprolite normally grades from clayey soils
near the land surface to highly weathered rock above competent bedrock.

The occurrence and movement of groundwater in the Blue Ridge is within two separate but
interconnected water-bearing zones. A shallow water-bearing zone occurs within the saprolite,
and a deeper water-bearing zone occurs within the underlying bedrock.

Groundwater in the shallow saprolite zone occurs in the interstitial pore spaces between the
grains comprising the saprolite soils. Groundwater in this zone is typically under water table or
unconfined conditions. Groundwater movement is generally lateral from recharge areas to small
streams which serve as localized discharge points.

The occurrence and movement of groundwater in underlying bedrock is controlled by secondary
joints, fractures, and faults within the bedrock. On a regional scale, the direction of groundwater
flow is typically from uplands to major streams and groundwater sinks. The saprolite has a
higher porosity than the bedrock and serves as a reservoir which supplies water to a network of
fractures in the bedrock.

Robbinsville/Report/AS_3030_28254_MRP_20221219_Monitoring Report.doc
4.2 Site Geology and Hydrogeology

Based on field observations during LSA activities by H&H in 2005, the site is generally
composed of surficial fill and alluvial soils consisting of tan-brown to brownish red sandy silts
and silty clays. Metasandstone bedrock was encountered below the soils at approximately 11 to
13 ft below ground surface (bgs). An alluvial layer of well-rounded pebbles and cobbles with
abundant groundwater is present just above bedrock. The pebbles and cobbles are assumed to be
present from previous meanders of Tulula Creek. Larger micaschist boulders were also
encountered above the bedrock. The boulders were encountered at depths ranging from three to
eight ft below ground surface.

H&H installed five shallow (MW-1 through MW-5) and one deeper monitoring well (DW-1) at
the site during LSA activities in January 2005. After installation, the top of casing elevations of
the monitoring wells were referenced to a common datum using surveying techniques. These
same wells were gauged and sampled in 2022. The depth to groundwater at the site is
approximately 4 to 5 ft below grade. H&H prepared a potentiometric map based on groundwater
elevations referencing an arbitrary datum. Based on the potentiometric map, the shallow
groundwater flow direction is generally to the west and toward Tulula Creek (Figure 4).

5.0 Groundwater Monitoring

5.1 Monitoring Wells and Water Levels

Six monitoring wells (MW-1 through MW-5 and DW-1) were sampled on September 6 and 7,
2022. The monitoring wells appeared to be in good condition. Monitoring well construction
information is provided in Table 2.

An electronic water level indicator was used to record the static water levels in the six existing
monitoring wells. The depths to water in shallow monitoring wells ranged from 4.53 ft (MW-5)
to 5.29 ft (MW-2) below the monitoring well top of casings. The estimated potentiometric
surface from September 2022 is depicted on Figure 4. As shown on Figure 4, the potentiometric
surface generally slopes to the west towards Tulula Creek.

5.2 Sample Collection Procedures and Analyses

Laboratory supplied sample containers were used for sample collection. A chain-of-custody
record was completed for samples collected and included sample description, date collected, time
collected, matrix, sample container information, and analyses required. The sample containers
were placed in a cooler with ice and submitted to Waypoint Analytical for laboratory analysis of
volatile organic compounds (VOCs) by Standard Method for the Examination of Water and
Wastewater 6200B and semi-VOCs by EPA Method 625 (base/neutral and acid extractables).
Laboratory analytical data sheets are provided in Appendix B, and analytical results are
summarized in Table 3.

5.3 Groundwater Sampling and Results

After monitoring wells were gauged for total well depth and depth to water, the wells were
sampled using low-flow sampling techniques with a peristaltic pump. H&H recorded pH,
temperature, oxidation reduction potential (ORP), conductivity, dissolved oxygen (DO), and
turbidity parameter measurements in the field, collected using a YSI Pro Plus and Hach
Turbidimeter. Once parameters of pH, temperature, and conductivity stabilized, a groundwater

Robbinsville/Report/AS_3030_28254_MRP_20221219_Monitoring Report.doc
sample was collected for laboratory analysis. Field parameter data are provided in Table 4.
Groundwater sampling forms are included in Appendix C.

Based on laboratory analytical results, concentrations of benzene (11.7 ug/L) and naphthalene
(21.2 ug/L) were detected in MW-1 above the 15A NCAC 2L .0202 Groundwater Quality
Standards (2L Standard) of 1.0 ug/L and 6.0 ug/L, respectively. Low level concentrations of
other petroleum-related VOCs were also detected in MW-1, MW-3, and MW-4 below the 2L
Standards. Low level concentrations of acetone and/or 4-methyl-2-pentanone were detected in
monitoring wells MW-3, MW-4 and DW-1 below their respective 2L standards. Acetone and 4-
methyl-2-pentanone are common laboratory introduced contaminants. With the exception of
naphthalene noted above, no other SVOCs were detected in monitoring wells at the Site.

The groundwater concentrations noted above were also compared to the NC Water Quality
Standards for Surface Water (2B Standards). The nearest discharge is to a Water Supply Class
III (WS-III) and a Trout Water (Tr) surface water body (Tulula Creek). Based on the
classification of the receiving water body downgradient of the site, concentrations detected in
groundwater were compared to criteria applicable for WS III/Tr surface water. Per NC Division
of Water Resources (DWR) guidance (NC DWR Surface Water Quality Standards, Criteria & In-
Stream Target Values table, July 2021), if no 2B Standards exist for certain compounds,
concentrations were also compared to the lower of the EPA National Recommended Water
Quality Criteria or NC In-Stream Target Values. Based on this comparison, concentrations of
petroleum constituents did not exceed 10 times the NC surface water criteria.

Concentrations of VOCs and SVOCs have significantly decreased in monitoring wells MW-1
through MW-4 and DW-1 since the 2005 sampling event. For example, benzene decreased from
320 µg/L in 2005 to 11.7 µg/L in 2022 in MW-1. VOCs and/or SVOCs previously detected in
wells MW-2 through MW-4 and DW-1 were not detected or were detected at concentrations
below their respective 2L Standards. The absence of impacts has remained consistent in
monitoring well MW-5 over time. Historical groundwater monitoring data are provided in Table
3. Contaminant concentrations are depicted on Figure 5.

6.0 Summary and Certification

Updated receptor survey activities and groundwater monitoring were conducted at the NC DOT
Maintenance Facility in Robbinsville, North Carolina. The findings are summarized below.

 Two water supply wells were identified within approximately 900 ft of the source at the
site. The water supply wells provide potable water to three residences and are used for
livestock. No other water supply wells were identified within a 1,500 ft radius of the site.
Municipal water is available in the area.

 Monitoring wells MW-1 through MW-5 and DW-1 were sampled for VOCs and SVOCs
in September 2022. Impacts above 2L Standards were only detected in one monitoring
well. Concentrations of benzene and naphthalene were detected in MW-1 above the NC
2L Standards. Low level concentrations of other petroleum-related VOCs were also
detected in MW-1, MW-3, and MW-4 below the 2L Standards. With the exception of
naphthalene, no other SVOCs were detected in monitoring wells at the site.
Concentrations of VOCs and SVOCs have significantly decreased in monitoring wells
MW-1 through MW-4 and DW-1 since the 2005 sampling event. Concentrations of
detected petroleum constituents did not exceed 10 times the surface water criteria in
September 2022.

Although the concentrations detected in September 2022 are low, only two groundwater
sampling events have been conducted and the site qualifies as high risk. H&H recommends one
additional sampling event for monitoring wells MW-1 through MW-5 and DW-1. The next
monitoring event can be conducted in March 2023. If similar groundwater concentrations are
found in the next sampling event, H&H will recommend incident closure because the water
supply wells are approximately 900 ft away and the stream is approximately 200 to 250 ft away
from groundwater impacts above standards.

Lab Report Number: 22-252-0027 Client Project Description: DOT-476
Dear David Graham:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 9/9/2022 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,
Angela D Overcash Senior Project Manager
