SECTION B. EXECUTIVE SUMMARY 

1. Summary of Activities Associated with Current TA 

WithersRavenel, Inc. (WR) conducted a groundwater monitoring event at the former Snipes 
Grocery site located at 5515 NC Highway 86 North in Cedar Grove, Orange County, North 
Carolina in association with TA‐03 under NCDEQ Contract #N122019B, approved by NCDEQ 
on December 12, 2022.  The scope of work for this project included the gauging, purging and 
sampling of existing monitoring wells MW‐1 through MW‐12, and the purging and sampling of 
water supply wells WSW‐1, WSW‐2, WSW‐7, WSW‐8, WSW‐9 and WSW‐13.  As well WSW‐1 
was found to be inactive, this well was not sampled.  WR was unable to gain access to wells WSW‐
2, WSW‐7, WSW‐8 and WSW‐9, so these wells were not sampled.   

2. Soil, Groundwater and LNAPL Assessment Information 

Soils 
No soil sampling was performed at the facility in association with the current TA.  Analytical results 
for a soil sample obtained from a depth of 27 feet (ft) beneath surface grade during the installation 
of MW‐3 by Agra Environmental (Agra) in preparation of their 2006 Comprehensive Site 
Assessment (CSA) for the site showed benzene, ethylbenzene and total xylenes at levels exceeding 
their respective Soil‐to‐Water Maximum Soil Contaminant Concentrations (MSCCs).  No other soil 
samples submitted for analysis by Agra at the time showed contaminants at levels exceeding 
MSCCs.  No focused assessment of soil impact at the site has been performed to date, and 
additional testing of soils in proximity to the pump island is warranted.   

Groundwater  
WR collected groundwater samples from site monitoring wells between January 11 and 12, 2023.   
These groundwater samples were submitted for laboratory analysis of VOCs by SM6200B and 
EDB by EPA Method 504.1.  Analytical results for the samples showed one or more compounds 
at concentrations exceeding their respective 2L Standards in samples from MW‐1, MW‐3, MW‐4 
and MW‐5.  EDB was reported in samples from MW‐3 at a level above the 2L Standard for the 
compound.  No compounds were reported in any samples at concentrations exceeding their GCL 
values.  Based on total BTEX concentrations, fluctuations in contaminant concentrations were 
seen over the December 2021 – January 2023 period.  Total BTEX concentrations within MW‐3, 
MW‐4 and MW‐5 showed decreases of 57%, 77% and 53%, respectively.  Total BTEX levels in 
MW‐1 showed a 360% increase, however no BTEX compounds were in excess of their respective 
2L Standards.  Naphthalene was the sole compound reported in MW‐3 at a level above its 2L 
Standard. The level of EDB declined in MW‐3 by 83%, while the compound decrease in MW‐4 by 
100%.  Fluctuations in contaminant noted during January 2023 may relate to groundwater 
occurring an average of 17‐ft shallower than that measured in December 2021.   

Free Product 
No free product has been measured in any wells installed as a part of assessment at the site, to 
date.

3.       Receptor Information 

A site receptor survey conducted by Agra in April 2006 identified the presence of sixteen active 
water supply wells (including the on‐site supply well WSW‐1) within 1,000 ft of the source area 
on the site (See note, below).   A subsequent inventory of supply wells conducted by Agra in May 
2007 identified the presence of four additional wells (WSW‐17, WSW‐18, WSW‐19 and WSW‐
20).  It was also found that the residence serviced by WSW‐14 was connected to WSW‐13, and 
WSW‐14 was removed from the list of identified supply wells within 1,000 ft of the site.  Based 
on the information presented in Agra’s receptor survey, as many as eight supply wells are located 
within 500 ft of the source area, while the remaining 12 supply wells are located between 500 and 
1,000 ft of the source area.  The site is currently under renovation for future use, and WSW‐1 is 
not currently in use.  Mr. John Roberts, renovating the property for use as a “grill & convenience 
store” has informed WR that he is having the site connected to a supply well he is installing some 
1,000 ft east of the site.  Mr. Roberts also stated to WR personnel on November 21, 2018 that he 
had engaged an attorney and was pursuing a lawsuit against Orange County relating to their 
conditions for issuing zoning and allowing for business use of the property based on his plans.  
Note: The residence serviced by WSW‐15 burned in early 2021, and the supply well was inactive 
in January 2023. 

4. Remediation Activities 

No remedial actions, beyond the closure of the UST systems in March 1994, have been performed 
at the site to date.  Placement of well booms in MW‐3 and MW‐4 had been routinely performed 
as a means of “interim remediation”.   

5. Recommendations 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 

 As an interim remedial measure, performance of an MMPE event centered on MW‐3 to reduce 
contaminant(s) present at levels exceeding the GCL.   
 Continued groundwater monitoring of the site to document contaminant trends. 
 Continued sampling of water supply wells located within 500 ft of the release area, primarily 
WSW‐1 (if in service), WSW‐7, WSW‐8 and WSW‐13. 
 Acquisition of well construction information for supply wells WSW‐13 and WSW‐15. 
 Following connection of site to off‐location supply well, abandonment of WSW‐1. 
 Renew efforts to obtain access to the Torain property located to the south of the source area 
for the purposes of installing two Type II monitoring wells to determine southern extent of 
groundwater impact.   
 Install a single DPT soil boring on the site in an effort to determine the interface of PWR and 
the overlying materials.   
 In the case that the UST systems could be removed (see notes, below), WR would recommend 
excavation of petroleum contaminated soils to the extent practical, followed by the 
assessment activities outlined below:

o Performance of horizontal and vertical soil and groundwater assessment in locations 
surrounding pump island and existing UST area on the property employing Membrane 
Interface/Hydraulic Profiling (MiHP) to determine appropriate areas for future 
remediation.   
o Performance of aquifer slug testing of three on‐site monitoring wells. 
o Collection and analysis of groundwater samples from three select monitoring wells for 
natural attenuative and engineering parameters to assist in development of a remedial plan 
for injection.  

Notes: Mr. John Roberts previously informed WR that his current plans for renovation of the 
property for use as a “grill & convenience store” include the placement of the existing UST systems 
back into service.  WR informed Mr. Roberts that he would be required to comply with NCDEQ 
regulations relating to the future use of the UST systems including but not limited to: 
o Ensuring that the systems meet current construction requirements including overfill 
protection and leak detection, 
o Registration and inspection of the UST systems in compliance with current NCDEQ 
requirements, 
o Payment of any past or future tank fees (if applicable) 

In the case that Mr. Roberts opts to continue development of the site without placing the UST 
systems back into service or is replacement of the systems back into service is not permitted, 
assessment and evaluation of remedial action at the facility would occur following closure of the 
existing systems and the recommended excavation of petroleum impacted soils.

SECTION C.  SITE HISTORY AND CHARACTERIZATION 

WR has completed a groundwater and supply well sampling event for the referenced site in 
association with TA‐03 at the facility.  The following information summarizes the site history and 
characterization.   

1. UST Information 

1.1 Former USTs 
The locations of the UST systems, onsite improvements, and the present onsite monitoring wells 
are depicted on Figure 2.  Two 1,000‐gal gasoline USTs, one 550‐gal kerosene UST and an 
additional 550‐gal UST of unknown use were permanently closed by removal during March 1994.  
These tanks were situated in a single UST area located adjacent to the southern side of the canopy 
formerly attached to the building on the site.  The pump island associated with these tanks was 
not removed at the time, and “new” UST systems were emplaced in the excavation at the 
conclusion of the tank removals.   
1.2 Existing USTs 
According to the PIB inspection report, four petroleum USTs are currently situated at the front 
(southwestern corner) of the facility on site.  These existing USTs include one 3,000‐gal (triple 
compartment) gasoline UST and one 350‐gal kerosene tank1.  The gasoline UST is plumbed to the 
pumps located along the edge of the former canopy and the kerosene tank to a pump situated at 
the front of the building on the site.   
WR made inquiries with the NCDEQ‐UST Section PIB for information relating to the existing USTs 
in place at the subject site associated with Facility ID 00‐0‐0000034070 (Chamber Mini Market).  
The existing USTs were reportedly installed in the same UST basin to the south of the pump island 
from which the former USTs were removed in 1994.  These USTs are currently out of service, the 
permit having expired on December 31, 2014.  The PIB provided WR the most recent inspection 
report for the facility, dated May 28, 2014.  Based on the “improper temporary closure” of the 
USTs, the inspection result was listed as a ”failure”.  This failure appears based on the possible 
presence of product in the tanks and a lack of verification that metal piping at the tops of the USTs 
are isolated and have corrosion protection, as STI‐P3® corrosion protection does not protect 
these parts.  Therefore, these tanks are currently not in compliance with NCDEQ regulations.   
A single 260‐gal AST was located along the northern exterior wall of the building on the property, 
and was not plumbed for use.  WR is unaware of the disposition this AST, as it was in‐place during 
June 2015.  Two additional ASTs of unknown volumes, utilized for the storage of propane or LP 
gas, are located along the southern wall of the building.  Table B‐1 summarizes information 
regarding USTs that were formerly utilized on the property, as well as available information related 
to the USTs and ASTs now located on the parcel.    

1 The NCDENR UST Facility Operating Permits Database (January 2015) shows the UST Permit for the site as
expired (as of December 31, 2014). Based on site observations during WR's visit to the facility, these tanks are
not currently utilized for the sale of fuel product(s), but may contain fuels or residuals.

2.       Description of Release/General Assessment History 

The following summary of the assessment history is based on WR’s review of historical files for 
the subject incident: 

 Four USTs (two 1,000‐gal gasoline, one 550‐gal kerosene, and one 550‐gal tank of previous 
unknown contents filled with cement) were reportedly removed from the site in March 1994.  
The FTF Single Incident Report for the site includes a statement that “a UST closure report 
was not submitted for the closure event”.  The USTs were replaced with a 3,000‐gal three 
compartment UST and a 350‐gal kerosene UST, which are currently located at the facility (see 
footnote 1 on page 7). 
 A sample was reportedly collected from the on‐site water supply well in March 1994. 
Analytical results for this sample indicated the presence of benzene and other petroleum 
constituents.  Subsequent analysis of samples from this well indicated the continued presence 
of petroleum constituents.  A point‐of‐entry (POE) system was reportedly installed at this well 
by the property owner. 
 A Comprehensive Site Assessment (CSA) was submitted by Agra Environmental, Inc. on August 
30, 2006.  This report concluded that the vertical and horizontal extent of soil and groundwater 
impact had not been defined and that a Corrective Action Plan (CAP) was required for the 
release at the facility. 
 Terraquest personnel collected groundwater samples from monitoring wells MW‐1 through 
MW‐8, and water supply wells WSW‐1, WSW‐2, WSW‐7, WSW‐8, WSW‐13, and WSW‐15 
on March 29, 2010.  Petroleum compounds were detected at concentrations in excess of 2L 
Standards in samples collected from monitoring wells MW‐3, MW‐4, and MW‐5 and in 
samples collected from water supply wells WSW‐1 and WSW‐8. 
 On October 31, 2011, Terraquest personnel sampled monitoring wells MW‐1 and MW‐3 
through MW‐8, inclusive, and water supply wells WSW‐2, WSW‐7, WSW‐8, WSW‐13, and 
WSW‐15. Petroleum compounds were detected at concentrations in excess of 2L Standards 
and GCLs in the sample collected from MW‐4, and 2L Standards in samples collected from 
monitoring wells MW‐1, MW‐3 and MW‐5, as well as supply wells WSW‐2, WSW‐7, and 
WSW‐8. 
 On November 9, 2012, Terraquest personnel sampled monitoring wells MW‐1 and MW‐4 
through MW‐8, and water supply wells WSW‐2, WSW‐7, WSW‐8, WSW‐13, and WSW‐15. 
Petroleum compounds were detected at concentrations in excess of the 2L Standards in 
samples collected from monitoring wells MW‐1, MW‐4, and MW‐5. 
 Crawford Environmental Services sampled supply wells WSW‐7, WSW‐13, and WSW‐15 on 
June 11, 2013. Analytical results showed MTBE at a concentration beneath the 2L Standard 
for the compound in the sample collected from supply well WSW‐13. No petroleum 
compounds were detected in supply wells WSW‐7 or WSW‐15.    
 WR performed a groundwater and supply well sampling event between November and 
December 2014.  Analytical results for groundwater samples indicated one or more petroleum 
compounds in samples obtained from monitoring wells MW‐3, MW‐4, MW‐5 and MW‐7.  One 
or more of the compounds identified in these wells were reported at levels exceeding their 
respective 2L Standard(s).  EDB was reported in the samples obtained from wells MW‐3 and

at levels exceeding their respective GCLs.  Analytical data for the supply well samples indicated 
the presence of several petroleum compounds in WSW‐1, and MTBE in WSW‐13.  Levels of 
benzene and 1,2‐DCA identified in WSW‐1 were reported at concentrations exceeding their 
respective 2L Standards.   
 Between July 27, October 6, and October 29, 2015, subsequent to obtaining access 
agreements, an NCDOT Right‐of‐Way Encroachment Agreement and monitoring well permits 
as required by NCDEQ, WR supervised the installation of Type II monitoring wells MW‐9, 
MW‐10, and MW‐11 at the facility. WR was originally tasked with oversight of the installation 
of four Type III (double cased) monitoring wells; however, review of the site’s assessment 
information indicated that the installation of the Type III wells would not be prudent at this 
time.  Following discussions with the NCDEQ Incident Manager for the site, which included 
discussions of whether or not to install deeper Type II monitoring wells, it was decided that 
installation of the Type III (or deeper Type II) wells would not be undertaken at the time.  In 
addition to the installation of wells MW‐9, MW‐10 and MW‐11, WR also gauged, purged and 
sampled monitoring wells MW‐1, MW‐2, MW‐3, MW‐4, MW‐5, MW‐7, MW‐8, MW‐9, MW‐
10 and MW‐11, purged and sampled supply wells WSW‐1, WSW‐13 and WSW‐15, and 
surveyed the relative TOC elevations for the newly installed monitoring wells.  WR was also 
tasked with the collection of supply well samples from WSW‐2, WSW‐7, WSW‐8 and WSW‐
9 in addition to those successfully sampled, but despite attempts at obtaining access to these 
additional supply wells through phone calls and visits to the properties, samples from these 
wells were not obtained as the wells were inaccessible. 
 Between August 4 and 5, 2016 WR gauged, purged and sampled monitoring wells MW‐1 
through MW‐11, purged and sampled supply wells WSW‐1, WSW‐2, WSW‐7, WSW‐8, 
WSW‐9, WSW‐13 and WSW‐15, and surveyed the relative TOC elevations for each of the 
monitoring wells relating to the release on the site. Analytical results for groundwater 
samples obtained from site monitoring wells indicated one or more petroleum‐related 
compounds at levels exceeding their respective 2L Standard(s) in samples from MW‐3, MW‐
4 and MW‐5.  No compounds identified in any groundwater samples were reported at 
concentrations above their respective GCLs.  Analytical results for samples from the 
remaining wells sampled by WR did not indicated the presence of compounds at 
concentrations exceeding the MDL for SM6200B. Analytical results for the samples obtained 
from water supply wells on August 5, 2016 indicated the presence of several compounds in 
the sample obtained from the on‐site supply well (WSW‐1).  Benzene and 1,2‐ DCA were 
reported in the sample at concentrations exceeding their respective 2L Standards and the US 
EPA Region IV MCL for drinking water.  Analytical results for WSW‐7 showed chloroform at 
a concentration above the laboratory MDL and bromodichloromethane at a concentration 
exceeding its 2L Standard.  Results for WSW‐8 and WSW‐9 showed 1,2‐DCP concentrations 
exceeding the 2L standard. Results for WSW‐13 showed MTBE present at a level of 3.4 
µg/L, which is beneath the 2L Standard for the compound.  Analytical results for the sample 
obtained from WSW‐15 did show the presence of contaminants at concentrations exceeding 
the laboratory MDLs for SM6200B or EPA‐504.1.

 Between October 6 and 9, 2017, WR performed additional assessment at the site including 
the installation of Type II monitoring well MW‐12, the surveying of the relative top of casing 
(TOC) elevation of the well, and performed a site‐wide groundwater monitoring event.  WR 
also purged and sampled select supply wells located in proximity to the release on the site.  
WR was originally tasked with oversight of the installation of two additional Type II monitoring 
wells (MW‐13 and MW‐14); however, WR was not granted access to the Torain or Pope 
properties to facilitate their installations.  Analytical results for groundwater samples obtained 
from site monitoring wells on October 9, 2017 indicated the presence of one or more 
petroleum‐related compounds in the samples obtained from MW‐3, MW‐4 and MW‐5 at 
concentrations in excess of their respective 2L Standards.  EDB was reported in the samples 
from wells MW‐3 and MW‐4 at concentrations above the 2L Standard for the compound.  No 
compounds identified in any groundwater samples were reported at concentrations above 
their respective GCLs.  The greatest concentrations of contaminants were noted in the vicinity 
of monitoring wells MW‐3 and MW‐4, situated in close proximity to the pump island and UST 
area on the site.  Analytical results for samples obtained from monitoring wells MW‐1, MW‐2, 
MW‐6, MW‐7, MW‐8, MW‐9, MW‐10, MW‐11 and MW‐12 did not show the presence of 
volatile organic compounds at levels exceeding the laboratory MDL for SM6200B, or EDB by 
EPA Method 504.1.  Laboratory results for supply well samples obtained from select wells in 
October 2017 showed the following: 
o Bromodichloromethane (at a concentration exceeding the 2L Standard for the compound) 
and chloroform were reported in the sample from WSW‐7.  These compounds are typical 
by‐products of well chlorination, and WR attributes their presence in the well to this 
process. 
o 1,2‐Dichloropropane (1,2‐DCP) was reported in the sample from WSW‐8 at a level above 
the 2L Standard for the chemical. 
o Methyl‐tertiary‐butyl‐ether (MTBE) and tertiary‐amyl‐methyl‐ether (TAME) were reported 
in the sample from WSW‐13 at levels beneath their respective 2L Standards.   
o Data for samples from supply wells WSW‐2 and WSW‐9 did not show compounds at 
concentrations above the laboratory MDL for SM6200B or EPA‐504.1.   
o Supply well WSW‐1 was not sampled during October 2017, as the well was inactive. 
o Supply well WSW‐15 was not sampled as Ms. Torain would not authorize its sampling 
during October 2017.   
 November 2018 ‐ Analytical results for groundwater samples obtained from site monitoring 
wells on November 21, 2018 indicated one or more petroleum‐related compounds at levels 
exceeding their respective 2L Standard(s) in samples from MW‐3, MW‐4 and MW‐5.  Data for 
EPA‐504.1 analysis (EDB) showed the compound present in samples from wells MW‐3 and 
MW‐4 at levels above the 2L Standard for the compound.    Analytical results for samples from 
the remaining wells sampled by WR did not indicate the presence of compounds at 
concentrations exceeding their respective 2L Standards, or above the MDL for EPA‐504.1.  No 
compounds identified in any groundwater samples were reported at concentrations above 
their respective GCLs.  Laboratory results for the samples obtained from water supply wells 
on November 21, 2018 showed bromodichloromethane (at a concentration exceeding the 2L 
Standard for the compound) and chloroform in the sample from WSW‐7.  MTBE was reported 
in the sample from WSW‐13 at a concentration beneath the 2L Standard for the compound.

3.  Brief Description of Site Characteristics 

The property is a ±0.78‐acre parcel located in Cedar Grove, Orange County, North Carolina (Figure 
1).  The structure on the property is currently under renovation, slated to be opened as the “Cock 
and Bull” grill/convenience store.  The Orange County, NC GIS Department identifies the property 
as NC PIN# 9868024620.  The property is currently owned by Ms. Tonya P. Snipes, who owned 
the property with her late husband, Robert L. Snipes. Ms. Snipes currently leases the property to 
Mr. John Roberts.    

The site is occupied by a two‐story concrete block building.  Three pump assemblies formerly 
utilized for sale of gasoline are situated in the front of the structure, on the western (road‐facing) 
side of the building. When active, these pumps were reportedly serviced by a three compartment 
3,000‐gal gasoline UST. A kerosene pump is located at the face of the building near the northern 
corner of the existing UST area, serviced by a 350‐gal kerosene UST.  Both USTs are currently in 
place, but out of service, and may contain residual product.  Electrical power is provided to the 
property through overhead power lines.  Potable municipal water is not available to the site or 
surrounding properties.  A septic tank and associated leach field are located along the southern 
boundary of the site.   

The current property tenant (Mr. John Roberts) is remodeling the store located on the property 
for use as a convenience store/grill.  Mr. Roberts indicated to WR personnel that there are plans 
to utilize the existing UST system(s) on the site after the installation of new pumps and/or a new 
pump island.  He also stated that he was connecting the property to a supply well he is installing 
on a property located some 1,000 ft from the site, however, permitting of this well is still under 
review by the Orange County Health Department.   

In addition to the building on the property, surface coverings at the facility include areas of 
concrete and asphalt (approximately 20% of surface area) and grass/gravel (approximately 80% of 
surface area).  Site features are depicted on Figure 2.

The areas surrounding the site are generally utilized as residential and agricultural properties.  The 
site is bounded along its western boundary by NC Highway 86 (beyond which lie residences and 
farm land), along its northern boundary by Saw Mill Road (SR‐1545), beyond which lie residential 
properties and cultivated farmland, along its eastern boundary by additional residential property, 
and along its southern boundary by an additional residential property, which is the location of 
Torain Mobile Home Repair Services.  Note: The residence located on the Torain parcel burned in 
early 2020 and is currently unoccupied. 

4.       Information on Receptors/Potential Receptors 

A site receptor survey conducted by Agra in April 2006 identified the presence of sixteen active 
supply wells (including the on‐site supply well WSW‐1) within 1,000 ft of the source area on the 
site.   A subsequent inventory of supply wells conducted by Agra in May 2007 identified the 
presence of four additional wells (WSW‐17, WSW‐18, WSW‐19 and WS‐20).  It was also found 
that the residence serviced by WSW‐14 was connected to WSW‐13, and WSW‐14 was removed 
from the list of identified supply wells within 1,000 ft of the site.  Based on the information 
presented in Agra’s receptor survey, as many as eight supply wells are located within 500 ft of the 
source area, while an additional twelve supply wells are located between 500 and 1,000 ft of the 
source area.  Details regarding supply wells (based on the information provided by Agra and other 
consultants) are presented in Table B‐5.  Receptor locations based on Terraquest Environmental’s 
April 2010 map are included on Figure 6.   

The North Carolina Division of Water Resources (NCDWR), Source Water Assessment Program 
(SWAP) lists a supply well identified as “North Orange Human Services Center Well #2” located at 
5800 NC Highway 86 as a “Non‐Transient, Non‐Community Water System” (TWS).  WR has found 
no record of this well having been identified in the past as a potential receptor; however, the 
reported well location is approximately 1,900 ft north‐northwest of the source area.   

Surface drainage through the area is generally channeled through wet weather ditches running 
parallel to the roadway(s).  The site is located near a topographic high point and drainage from the 
intersection of NC Highway 86 and Sawmill Road runs to the east, west and south, dependent 
upon the location relative to the road intersection.  Surface drainage from the site appears to move 
to the southeast, towards an un‐named tributary of Ray’s Creek, draining to the South Fork of the 
Little River and ultimately discharging to the Neuse River Drainage Basin.

SECTION D.  GROUNDWATER INVESTIGATION – JANUARY 2023 

On January 11, 2023, WR personnel mobilized to the subject property to perform groundwater 
sampling activities at the facility in association with TA‐03 under NCDEQ Contract # N122019B.  
The following paragraphs describe the sampling activities and associated laboratory analytical 
results.  

D.1. GROUNDWATER SAMPLING 

Prior to sampling of monitoring wells located on the site as described below, each well was opened 
after which the well(s) were gauged with a decontaminated electronic water level indicator.  Depth 
to water within the wells as measured on January 11, 2023 ranged from 7.35‐ft beneath the top 
of casing (BTOC) in MW‐2 to 13.93‐ft BTOC in MW‐10.  Based on measurements obtained in 
January 2023, groundwater flow through the site trends divergently to the west and east from a 
lie generally running north‐south at the front of the site.  This flow differs from historical trends at 
the location, which have been to the south, south, showing a westerly trend between MW‐1 and 
MW‐3.  Groundwater elevations averaged 17.3‐ft shallower than those measured in December 
2021 which has affected interpretation of groundwater flow.  I addition, groundwater as measured 
in January 2023 occurred at levels above the screened sections of each monitoring well.  
Groundwater measurement data for this event are included in Table B‐7, while a gradient map is 
included as Figure 3.  Historical groundwater elevation measurements are included in Table B‐9.  
Field notes and a photographic record are provided in Appendix B.  In the completion of well 
gauging, WR did not note the presence of free product within any wells gauged.   

Following gauging, monitoring wells were purged and sampled using separate, disposable, 
dedicated polyethylene (PE) bailers for each well.  Samples from the wells were decanted into pre‐
preserved laboratory provided sample containers.  Samples collected from site monitoring wells 
between January 11 and 12, 2023 were submitted to Waypoint Analytical, LLC (Waypoint) for 
testing by Standard Method (SM) 6200B and EDB by EPA Method 504.1.   
Laboratory Results 
Analytical results for the samples showed one or more compounds at concentrations exceeding 
their respective 2L Standards in samples from MW‐1, MW‐3, MW‐4 and MW‐5.  EDB was 
reported in samples from MW‐3 at a level above the 2L Standard for the compound.  No 
compounds were reported in any samples at concentrations exceeding their GCL values.  These 
results are shown on Figure 4 and included in Table B‐4.  Copies of the laboratory analytical report 
and chain‐of‐custody are included in Appendix A.   
Based on total BTEX concentrations, fluctuations in contaminant concentrations were seen over 
the December 2021 – January 2023 period.  Total BTEX concentrations within MW‐3, MW‐4 and 
MW‐5 showed decreases of 57%, 77% and 53%, respectively.  Total BTEX levels in MW‐1 showed 
a 360% increase, however no BTEX compounds were in excess of their respective 2L Standards.  
Naphthalene was the sole compound reported in MW‐3 at a level above its 2L Standard. The level 
of EDB declined in MW‐3 by 83%, while the compound decrease in MW‐4 by 100%.  Fluctuations 
in contaminant noted during January 2023 may relate to groundwater occurring an average of 17‐
ft shallower than that measured in December 2021.

D.2. SUPPLY WELL SAMPLING 

WR personnel obtained supply well samples from WSW‐13 on January 12, 2023 following 
purging.  The well was purged by allowing the associated well pump to run continuously for a 
minimum of ten minutes, after which a sample was decanted directly from the sample point into 
laboratory‐prepared sample containers holding appropriate preservative as required.  Supply well 
samples were submitted to Waypoint for analysis by SM6200B and EPA‐504.1 (EDB).    
Laboratory results for supply well samples obtained from WSW‐13 in January 2023 showed the 
presence of MTBE at a level beneath the 2L Standard.  The presence of MTBE and concentration 
of the compound reported in the sample from WSW‐13 is consistent with past sampling events.

SECTION E.  CONCLUSIONS AND RECOMMENDATIONS 

This report documents the results of field activities conducted at the site for TA‐03, which included 
the purging and sampling of monitoring wells MW‐1 through MW‐12 and, collection of supply 
well samples from WSW‐13.  Conclusions based on observations, analytical data and research 
relating to the release at the site combined with historical information include the following: 

 In addition to on‐site supply well WSW‐1 (currently out‐of‐service), WSW‐15 (also out of 
service), six sole‐source water supply wells are located within 500 ft of the site.  As many as 
12 additional supply wells are located within 1,000 ft of the site.   
 Analytical results for groundwater samples showed one or more compounds at concentrations 
exceeding their respective 2L Standards in samples from MW‐1, MW‐3, MW‐4 and MW‐5. 
 EDB was reported in samples from MW‐3 at a level above the 2L Standard for the compound.  
 No compounds were reported in any samples at concentrations exceeding their GCL values.   
 Analytical results for groundwater samples obtained from the remaining monitoring wells in 
January 2023 did not show impact by VOC compounds at concentrations exceeding their 
respective 2L Standards, or at levels above the MDL for EPA‐504.1.   
 The lateral extent of the contaminant plume has not been defined to levels equivalent to the 
2L Standards to the south and southeast of the source area on site.  The greatest 
concentrations of contaminants were noted in the vicinity of the former pump island and the 
western side of the UST area, to include the locations of MW‐3 and MW‐4.  Contaminants 
appear to extend hydraulically down‐gradient of these areas to the south and southeast of the 
source area.   
 No free product was identified on the site during the January 2023 sampling event, nor has 
free product been identified by previous consultants. 
 Based on measurements obtained in January 2023, groundwater flow through the site trends 
divergently to the west and east from a lie generally running north‐south at the front of the 
site.  This flow differs from historical trends at the location, which have been to the south, 
south, showing a westerly trend between MW‐1 and MW‐3.  Groundwater elevations 
averaged 17.3‐ft shallower than those measured in December 2021 which has affected 
interpretation of groundwater flow.  I addition, groundwater as measured in January 2023 
occurred at levels above the screened sections of each monitoring well.   
 Fluctuations in total BTEX concentrations were seen over the December 2021 – January 2023 
period.  Total BTEX concentrations within MW‐3, MW‐4 and MW‐5 showed decreases of 
57%, 77% and 53%, respectively.  Total BTEX levels in MW‐1 showed a 360% increase, 
however no BTEX compounds were in excess of their respective 2L Standards.  Naphthalene 
was the sole compound reported in MW‐3 at a level above its 2L Standard.  
 The level of EDB declined in MW‐3 by 83%, while the compound decrease in MW‐4 by 100%.  
Fluctuations in contaminant noted during January 2023 may relate to groundwater occurring 
an average of 17‐ft shallower than that measured in December 2021.   
 Laboratory results for supply well samples obtained from WSW‐13 in January 2023 showed 
the presence of MTBE at a level beneath the 2L Standard.  The presence of MTBE and 
concentration of the compound reported in the sample from WSW‐13 is consistent with past 
sampling events.

 No evaluation of groundwater occurring in “deeper” aquifer(s) at the property has been 
undertaken, to date, and the continued detection of petroleum‐related compounds in select 
supply wells may be indicative of migration of contaminants into “deeper” aquifer(s) through 
the operation of supply wells or preferential pathways within deeper water‐bearing strata.   
 The most recent UST Compliance Inspection report for the facility, completed on May 29, 
2014 indicated a “failure” of the existing on‐site UST systems based on the improper 
temporary closure of the tanks, and the possible presence of residual product within the USTs.  
In addition, no verification could be made of corrosion protection for metal piping components 
at the tops of the tanks, as STI‐P3® corrosion protection does not protect these parts.  The 
current lessor of the property (Mr. Roberts) has indicated to WR that his plans for renovation 
of the site include placing the existing UST systems back in service (See notes in 
recommendations, below). 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 

 As an interim remedial measure, performance of an MMPE event centered on MW‐3 to reduce 
contaminant(s) present at levels exceeding the GCL.   
 Continued groundwater monitoring of the site to document contaminant trends. 
 Continued sampling of water supply wells located within 500 ft of the release area, primarily 
WSW‐1 (if in service), WSW‐7, WSW‐8 and WSW‐13. 
 Acquisition of well construction information for supply wells WSW‐13 and WSW‐15. 
 Following connection of site to off‐location supply well, abandonment of WSW‐1. 
 Renew efforts to obtain access to the Torain property located to the south of the source area 
for the purposes of installing two Type II monitoring wells to determine southern extent of 
groundwater impact.   
 Install a single DPT soil boring on the site in an effort to determine the interface of PWR and 
the overlying materials.   
 In the case that the UST systems could be removed (see notes, below), WR would recommend 
excavation of petroleum contaminated soils to the extent practical, followed by the 
assessment activities outlined below: 

o Performance of horizontal and vertical soil and groundwater assessment in locations 
surrounding pump island and existing UST area on the property employing Membrane 
Interface/Hydraulic Profiling (MiHP) to determine appropriate areas for future 
remediation.   
o Performance of aquifer slug testing of three on‐site monitoring wells. 
o Collection and analysis of groundwater samples from three select monitoring wells for 
natural attenuative and engineering parameters to assist in development of a remedial plan 
for injection.

Notes: Mr. John Roberts previously informed WR that his current plans for renovation of the 
property for use as a “grill & convenience store” include the placement of the existing UST systems 
back into service.  WR informed Mr. Roberts that he would be required to comply with NCDEQ 
regulations relating to the future use of the UST systems including but not limited to: 
o Ensuring that the systems meet current construction requirements including overfill 
protection and leak detection, 
o Registration and inspection of the UST systems in compliance with current NCDEQ 
requirements, 
o Payment of any past or future tank fees (if applicable) 

In the case that Mr. Roberts opts to continue development of the site without placing the UST 
systems back into service or is replacement of the systems back into service is not permitted, 
assessment and evaluation of remedial action at the facility would occur following closure of the 
existing systems and the recommended excavation of petroleum impacted soils.   

WR appreciates the opportunity to be of service in the completion of these assessment activities.  
Should you have questions, comments, or require additional information, please contact WR at 
your earliest convenience.

No closure report for the removal of tanks # 001, 002, 003 and 004 was submitted to NCDENR. Laboratory data for a water supply well sample obtained from the on-site supply well (WSW-1) during March 1994 showed impact by petroleum constituents, indicative of a release from one or more of the USTs closed during March 1994. No information is available describing the nature or estimated volume(s) of the release(s) from the USTS.5515 NC Highway 86Cedar Grove, Orange County, NCIncident Number: 12315UST Information from Agra Environmental, Inc., Comprehensive Site Assessment Report, August 30, 2006.UST # 004 was reportedly "filled with cement" prior to its closure by removal in March 1994.Information for existing tanks (#005 and 006) from NCDENR "tblAllTanks" database. Data for the site last updated December 3, 2009. The NCDENR "UST Facility Operating Permits Database" (January 2015) shows the UST Permit for the site as expired (as of December 31, 2014). Based on site observations during W&R's visit to the facility, these tanks are not currently utilized for the sale of fuel product(s), but may contain fuels or residuals.Description of ReleaseUST # 005 is a three compartment tank (now or formerly) utilized for the storage of gasoline. The tank is reportedly divided by two compartments of 1,350 gallon capacities and a single compartment of 250 gallon capacity. UST # 006 is reportedly of 350 gallon capacity and (now or formerly) utilized for the storage of kerosene. Page 1 of 1

Soil Sampling, Soil Boring and Monitor Well Installation, Well Development

Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary
drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are
typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push
stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may
be collected from drill cuttings associated with the boring or well installation.

Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC
casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well
Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells).
Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well
screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay
seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus
space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas
where shallow groundwater is encountered, a variance to construction standards may be employed to
ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be
completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down
covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are
secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at
or above grade, and are abandoned within 24-hours of their installation.

Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump,
dependent upon site conditions. When wells are developed by the driller, they may be developed with
any of the methods outlined above, in addition to air or water injection. Soil boring logs and well
construction details are typically prepared for presentation in a report appendix. Borings completed in
bedrock may be drilled using air rotary, coring, or sonic drilling methods.

Groundwater Depth to Water Measurements

Groundwater level measurements are typically obtained using an electronic water level indicator which
registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater
measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot
intervals into the well until the probe of the meter intersects the water surface. The measurement from
the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The
electronic water level indicator probe and exposed probe cable is decontaminated between measurement
locations.

Free Product Level Measurements

Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using
an electronic oil/water interface probe. The interface probe has both an audible and illuminating light
that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and
solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when
groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe
attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the
product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are
recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to
LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is
decontaminated between measurement locations.

Soil Sampling and Field Screening

Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling
procedures are followed to protect the chemical integrity of the soil samples and minimize the potential
for cross contamination between sample locations, including discarding of the exterior of the sample
which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling
equipment, and the thorough decontamination of sampling apparatus prior to use and between sample
locations.

Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from
the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples
from excavation equipment includes retrieving native soil from material that has not made contact with
the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers
as described above.

Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample
integrity and minimize the potential for cross contamination or field personnel exposure to contaminants.
Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or
shovels, are decontaminated prior to their use in the collection of samples.

Samples are placed within laboratory grade sample containers provided by the laboratory to which the
samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is
typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening
of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other
portable screening device.

Screening of samples with a PID, FID or other field screening device is performed in accordance with
device manufacturer specifications for screening, following calibration of the instrument based on
manufacturer recommended procedures.

Groundwater Sampling

Groundwater samples are generally collected using one of three standard methods – through the use of a
dedicated, disposable bailer, a peristaltic pump or submersible electric pump.

When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the
well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes
of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to
recover to within 80% of the original level measured prior to purging.

When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is
emplaced into the screened section of the monitoring well, and the pump is used to extract water through
the tubing. When using the either of these methods, general water quality measurements including but
not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific
conductivity and turbidity may be used as methods for determining when an adequate purge of the well
has been conducted. When water quality parameters are measured, the resulting data are included in
well purge forms or field notes specific to each site and sampling point.

Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of
monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater
sample(s) are introduced directly into sample containers provided by the laboratory to which samples are
ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-
preserved container(s) provided by the laboratory.

Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample
integrity and minimize the potential for cross contamination of samples or field personnel exposure to
contaminants.

Water Supply Well Sampling

Sampling of water supply wells is accomplished through the collection of a representative sample from an
in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a
point prior to any filtration or point of entry (POE) system which might be installed on a well. In some
cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples
through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized
water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse.

In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the
well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is
contained in laboratory grade sample containers as described in the previous section. Water quality
parameters may be (but are not necessarily) measured in association with the well purging.

Supply wells without active power supplies are not generally sampled, as the well seal cannot be
compromised by individuals not certified as a well contractor. However, in the case of a well with no
power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or
electric submersible pump.

Decontamination Procedures

Decontamination procedures employed in the performance of field activities will vary dependent upon
the method(s) of sampling performed at any site, but will generally include the following:

• Remove excess soil/sludge from any sampling equipment as needed,
• Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a
contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as
necessary,
• Rinse thoroughly with tap water,
• Rinse thoroughly with analyte-free water (deionized water),
 Rinse thoroughly with isopropyl alcohol,
• Allow the equipment to air dry,
• Prevent inadvertent contamination during storage and transport (accomplished through storage of
equipment in foil or plastic bags/sheeting).

In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may
be decontaminated prior to their disposal. In general, no decontamination of these items is necessary
prior to their use in sampling.
