SECTION B. EXECUTIVE SUMMARY 

1. Summary of Activities Associated with Current TA 

WithersRavenel, Inc. (WR) purged and sampled monitoring wells located at the site (excepting 
MW‐11) and purged and sampled supply well WSW‐1 in association with TA‐04 under NCDEQ 
Contract #N122019B.   

2. Soil, Groundwater and LNAPL Assessment Information 

Soils 
No soil samples were obtained from locations on site in connection with the current task 
authorization.  1,896.14 tons of petroleum‐product impacted soil were excavated from the former 
UST areas during April/May 2008 (95 ft x 55 ft x 10 ft deep).  Based on data for samples obtained 
at completion of excavation, contaminants are likely present at levels exceeding Soil to 
Groundwater MSCCs. 

Groundwater  
Laboratory analytical results for groundwater samples obtained from site monitoring wells in 
January 2023 showed one or more target compounds in samples from monitoring wells MW‐1R, 
MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9, MW‐12, MW‐15, MW‐19, MW‐21 and 
MW‐23 at concentrations exceeding their respective 2L Standards established by 15A NCAC 2L, 
.0202 (Water Quality Standards for Class GA Groundwater).  No compounds were reported in any 
samples at concentrations exceeding their Gross Contaminant Levels (GCLs).  
Based on the current analytical results and those from previous sampling events conducted at the 
site, the lateral extent of groundwater contamination in the surficial aquifer has not been defined 
to the west of MW‐23, located to the northwest of the source area.  Minor data gaps exist to the 
south and east of MW‐19 MW‐21.  Results for analysis of groundwater samples obtained in 
January 2023 compared to data for the most recent previous sampling event showed increases in 
total VOCs in wells MW‐3, MW‐6, MW‐7, MW‐20 and MW‐21, while decreases were seen in 
wells MW‐1R, MW‐5, MW‐8, MW‐10, MW‐12, MW‐19 and MW‐23.  The increase in well MW‐
6 appeared significant, showing an increase from 45 to 10,282 µg/L in total VOCs.   
Groundwater elevations as measured in January 2023 show a divergent shallow gradient 
“radiating” to the northwest, west, southwest, and northeast. The shallow gradient appears to flow 
in these divergent directions from near a line between MW‐7 and MW‐10.  Previous 
interpretations of groundwater flow showed a divergent flow generally centered on the former 
UST area and area of excavation on the property.  The presence of non‐native fill materials in 
contact with shallow groundwater in the excavated area may serve as a “sink” where groundwater 
movement is less affected than that in saturated (native) soils surrounding the excavation.  
Groundwater flow as measured in the “deep” aquifer represented by MW‐14D, MW‐16D and 
MW‐18D in January 2023 showed a gradient trending to the north‐northwest.

LNAPL/Free Product 
No LNAPL/free product has been identified on the site, to date, however, petroleum sheens were 
noted in wells MW‐5, MW‐9 and MW‐19 when measured in February 2013. 
3.       Receptor Information 
WR completed a receptor survey update in association with a previous TA under the current 
contract.  Results of this update included the following: 

 Potable water is available for use to several properties in proximity to the site, however private 
water supply wells are still in use at select locations surrounding the site.   
 One active potable supply well (WSW‐8) was found to lie within 500‐ft of the source location. 
 Three additional active, potable wells (WSW‐3, WSW‐7 and WSW‐14) were identified 
between 500‐ and 1,000‐ft of the source area. 
 Two active, potable wells (WSW‐5 and WSW‐13) were identified between 1,000‐ and 1,500‐
ft of the source area. 
 Two non‐potable or inactive supply wells (WSW‐2 and WSW‐4) were found to lie within 500‐
ft of the source location. 
 An additional seven non‐potable or inactive supply wells (WSW‐1A, WSW‐1B, WSW‐6, 
WSW‐9, WSW‐10, WSW‐11 and WSW‐12) were identified between 500‐ and 1,000‐ft of the 
source area.   
 The National Wetlands Inventory, administered by the U.S. Fish and Wildlife Service identifies 
a Freshwater Pond Habitat approaching to within approximately 345‐ft southeast of the 
source area, an additional Freshwater Pond Habitat approaching to within approximately 625‐
ft north, a Freshwater Forested Shrub Wetland approaching to within approximately 580‐ft 
south, a Riverine Habitat approximately 827 ft north and a Freshwater Forested/Shrub 
wetland approximately 910 ft northwest of the source area.   
 The NCDEQ Source Water Assessment Program (SWAP) does not list any surface water 
intakes, wellhead protection areas or community supply wells within a 1‐mile radius of the 
source area.   

WR obtained a sample from supply well WSW‐1 (non‐potable well located to the northwest of 
the site) on January 10, 2023.  Results of analysis by SM6200B showed naphthalene present at a 
concentration beneath the 2L Standard for the compound.   

4. Remediation Activities 
Remedial activities performed at the site include the removal of the USTs from the location in 
1994 and the excavation/off‐site disposal of 1,896.14 tons of contaminated soil in April/May 
2008.

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

 Performance of chemical amendment injection in the vicinity of wells MW‐5 and MW‐6 as a 
means to reduce contaminant concentrations to levels beneath GCLs.   
 Continued annual groundwater and supply well monitoring at the site to map contaminant 
trends.  
 Based on current groundwater data and site risk, perform additional assessment to the western 
and southern areas of groundwater impact.

facility.  In addition, the on‐site supply well was found to have been impacted at levels exceeding 
NC 2L Standards.   
June 2000 – WR installed monitoring well MW‐4 and advanced a total of 16 soil borings at the 
facility.   
March 2001 – WR obtained samples from MW‐1 though MW‐4 and supply well samples from the 
on‐site well and four additional wells located on surrounding properties.  Laboratory results 
showed one or more petroleum compounds in MW‐1, MW‐2 and MW‐4 at levels above 2L 
Standards.  Data for the on‐site supply well showed impact by petroleum compounds at levels 
exceeding 2L Standards.   
July 2001 – WR Completed additional assessment of the release on the property and oversaw the 
abandonment of the on‐site supply well.

April/May 2008 ‐ 1,896.14 tons of petroleum‐product impacted soil was excavated from the 
former UST areas (95 ft x 55 ft x 10 ft deep).  Based on data for samples obtained at completion 
of excavation, contaminants likely present at levels exceeding Soil to Groundwater MSCCs. 
June 2009 ‐ AGRA Environmental completed supply well sampling activities at the site including 
the sampling of ten supply wells.  Laboratory results for the wells sampled (WSW‐1A, WSW‐1B, 
WSW‐2, WSW‐4, WSW‐6, WSW‐7, WSW‐8, WSW‐9, WSW‐11 and WSW‐12) did not show 
impact by petroleum compounds.   
August 2011 ‐ AGRA Environmental completed groundwater and supply well sampling activities 
at the site.  Results for groundwater samples showed petroleum impact at levels above 2L 
Standards in MW‐1R, MW‐4, MW‐5, MW‐6, MW‐8, MW‐9, MW‐11, MW‐12 and MW‐19.

3.  Brief Description of Site Characteristics 

The property is a 2.31‐acre parcel located in a rural incorporated area of West End, Moore County, 
North Carolina (Figure 1), with an approximate elevation of 478 ft above mean sea level (AMSL).  
The Moore County, NC GIS Department identifies the property as GPIN 856500171579, 
addressed as 1093 Doubs Chapel Road, and indicates that the property is currently owned by 
Stephen L. & Charity C. Blanchard.   The site is currently used as a retail thrift store and 
consignment shop. 
A single‐story block structure is located along the northeastern portion of the property, along with 
a block outbuilding.  An additional wood framed outbuilding is located to the south of the primary 
structure.  The northeastern portion of the site north and east of the central building on the 
property includes an asphalt paved area.  The remainder of the parcels is covered with grass, and 
gravel covered areas and moderate to heavy shrub and tree growth.  Existing site features are 
depicted on Figure 2.  Surface drainage through the area is generally channeled through ditches 
running parallel to roadways.  As the site is located at a topographic high, overland flow at the 
location is expected to trend to the north and west towards a tributary of the Deep River, or south 
and east towards a tributary of the Little River. Regional drainage flows into the Cape Fear River 
Drainage Basin.    
The areas surrounding the site are generally used for residential and/or agricultural purposes.  The 
site is zoned by Moore County as “B‐1” (Business).  Surrounding properties are zoned as 
“Residential/Agricultural”

4.       Information on Receptors/Potential Receptors 

WR completed a receptor update in association with a previous task authorization for the site.  
Results of the update include the following: 
Water Supply Wells 
WR surveyed the area surrounding the site extending to an approximate 1,000 ft radius to 
determine the presence or absence of water supply wells.  In the performance of the survey, WR 
found the following:   

 Potable water is available for use to several properties in proximity to the site, however private 
water supply wells are still in use at select locations surrounding the site.   
 One active potable supply well (WSW‐8) was found to lie within 500‐ft of the source location. 
 Three additional active, potable wells (WSW‐3, WSW‐7 and WSW‐14) were identified 
between 500‐ and 1,000‐ft of the source area. 
 Two active, potable wells (WSW‐5 and WSW‐13) were identified between 1,000‐ and 1,500‐
ft of the source area. 
 Two non‐potable or inactive supply wells (WSW‐2 and WSW‐4) were found to lie within 500‐
ft of the source location. 
 An additional seven non‐potable or inactive supply wells (WSW‐1A, WSW‐1B, WSW‐6, 
WSW‐9, WSW‐10, WSW‐11 and WSW‐12) were identified between 500‐ and 1,000‐ft of the 
source area.   

Water Supply 
Potable water is available to the site and surrounding properties through the Moore County Water 
Department, East Moore Water District (PWS ID NC50‐63‐011).  “The water source that is used 
by East Moore Water District is fully treated surface water purchased from Harnett County. The 
metered interconnections are located at Line Road/Cypress Church Road Intersection near the 
Moore County/Harnett County Line. East Moore Water District purchases fully treated surface 
water from Harnett County whose source is from the Cape Fear River.”  

Wellhead Protection Areas and Community Supply Wells 
 The NCDEQ Source Water Assessment Program (SWAP) does not list any surface water 
intakes, wellhead protection areas or community supply wells within a 1‐mile radius of the 
source area.   
 The nearest listed wellhead protection area is located approximately 3‐miles east of the site, 
on the eastern side of Aurora, NC.   

Surface Water Bodies and Wetland Habitats 
The National Wetlands Inventory, administered by the U.S. Fish and Wildlife Service identifies the 
following features in proximity to the source location: 

• A Freshwater Pond Habitat approaching to within approximately 345‐ft southeast of the 
source area. Designation “PUBHh” (Paulustrine, Unconsolidated Bottom, Permanently 
Flooded, Diked/Impounded).

• A Freshwater Pond Habitat approaching to within approximately 625‐ft north. Designation 
“PUBHh” (Paulustrine, Unconsolidated Bottom, Permanently Flooded, Diked/Impounded). 
• A Freshwater Forested Shrub Wetland approaching to within approximately 580‐ft south. 
“PFO1B” indexed as “Paulustrine, Forested, Broad‐Leaved Deciduous, Seasonally Saturated”.   
• A Riverine Habitat approximately 827 ft north.  “R4SBC” indexed as “Riverine, Intermittent, 
Streambed, Seasonally Flooded”. 
• A Freshwater Forested/Shrub wetland approximately 910 ft northwest of the source area.  
“PFO1Fh” indexed as “Paulustrine, Forested, Broad‐Leaved Deciduous, Semi‐Permanently 
Flooded, Diked/Impounded”.   

Geologic Setting 
The 1985 Geologic Map (NC Department of Natural Resources and Community Development, 
Division of Land Resources, North Carolina Geological Survey) indicates that the site is situated 
within the Middendorf Formation of the Coastal Plain Physiographic Province.  The Middendorf 
formation of Cretaceous age is characterized “Sand, sandstone, and mudstone, gray to pale gray 
with an orange cast, mottled; clay balls and iron‐cemented concretions common, beds laterally 
discontinous, cross‐bedding common.”   
The site is located within the western portion of the Coastal Plain Physiographic Province of North 
Carolina (Coastal Plain) in a location in which movement of surficial groundwater to deeper water‐
bearing formations of underlying aquifers may occur.  The site is located at the Southwestern edge 
of the Northern Atlantic Coastal Plain Aquifer System, consisting of a sequence of layered 
sedimentary aquifers including sands and gravels, separated by aquitards.  These layers “dip” or 
slope to the east and extend beneath the continental shelf, offshore.  The site is mapped by the 
USGS as lying in an area where “unconsolidated sands compose the surficial aquifer, which is the 
uppermost water yielding part of the aquifer system”.   
Installation and sampling of Type III monitoring wells MW‐14D, MW‐16D and MW‐18D have not 
shown impact by petroleum contaminants, to date.  This implies that deeper water bearing aquifers 
beneath the site have not been impacted by the release on the property.   

Table B‐5A summarizes the Public & Private Water Supply Well Information while additional 
receptors are identified in Table B‐5B.  Receptor locations are depicted on Figure 6.

SECTION D.  ASSESSMENT & SAMPLING ACTIVITIES – JANUARY 2023 

WR conducted assessment activities at the location in association with TA‐04 under NCDEQ 
Contract #N122019B approved on December 12,2022.  These activities are described below. 

D.1. GROUNDWATER SAMPLING – JANUARY 2023 

WR mobilized to the site on January 9, 2023 for the purposes of gauging, purging and sampling 
site monitoring wells and supply well WSW‐1. These activities are described in the following 
sections.   

Well Gauging / Groundwater Elevations 
Prior to the purging and sampling of site monitoring wells, as described below, WR personnel 
opened and gauged each well slated for sampling with an electronic water level indicator to 
determine the depth to groundwater within each of the wells.  In the performance of these 
activities, no free product was measured within the monitoring wells gauged on January 9, 2023.  
WR was unable to locate monitoring well MW‐11,  therefore, the well was neither gauged nor 
sampled.   
Depth to water measurements for the monitoring wells measured ranged between 2.49‐ft beneath 
the top of well casing (BTOC) in MW‐15 to 23.67‐ft BTOC in Type III well MW‐16D.  Groundwater 
elevations as measured in January 2023 show a divergent shallow gradient “radiating” to the 
northwest, west, southwest, and northeast. The shallow gradient appears to flow in these 
divergent directions from near a line between MW‐7 and MW‐10.  Previous interpretations of 
groundwater flow showed a divergent flow generally centered on the former UST area and area 
of excavation on the property.  The presence of non‐native fill materials in contact with shallow 
groundwater in the excavated area may serve as a “sink” where groundwater movement is less 
affected than that in saturated (native) soils surrounding the excavation.  In addition, the 
intersection of Doubs Chapel Road and Murdocksville Road represents a local geographic “high 
point”.  Groundwater flow as measured in the “deep” aquifer represented by MW‐14D, MW‐16D 
and MW‐18D in January 2023 showed a gradient trending to the north‐northwest.   Groundwater 
elevation measurement data for this event are presented in Table B‐7, while historical 
groundwater elevation measurements are included in Table B‐9.   

Well Purging / Groundwater Sampling 
Between January 9 and 10, 2023 WR personnel collected groundwater samples from each site 
monitoring well following gauging and purging, with the exception of MW‐11, which could not be 
located.   Each well was purged using separate, disposable bailers as described in the procedures 
outlined in Appendix C.  Field notes associated with the sampling activities completed at the site 
are included in Appendix B.  Following the purging of each well, groundwater samples were 
decanted directly from dedicated bailers into laboratory‐prepared sample containers holding 
appropriate preservative(s) as required.  Groundwater samples were submitted to Waypoint 
Analytical, LLC (Waypoint) for analysis by SM6200B (VOCs).

Laboratory Results 
Laboratory analytical results for groundwater samples obtained from site monitoring wells in 
January 2023 showed one or more target compounds in samples from monitoring wells MW‐1R, 
MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9, MW‐12, MW‐15, MW‐19, MW‐21 and 
MW‐23 at concentrations exceeding their respective 2L Standards established by 15A NCAC 2L, 
.0202 (Water Quality Standards for Class GA Groundwater).  No compounds were reported in any 
samples at concentrations exceeding their Gross Contaminant Levels (GCLs).  Notably, benzene 
had been reported in MW‐12 at a level above the GCL in January 2022.  The presence of benzene 
in the well deceased by 18% over the January 2022 – January 2023 period.   
Based on the current analytical results and those from previous sampling events conducted at the 
site, the lateral extent of groundwater contamination in the surficial aquifer has not been defined 
to the west of MW‐23, located to the northwest of the source area.  Minor data gaps exist to the 
south and east of MW‐19 MW‐21.  Results for analysis of groundwater samples obtained in 
January 2023 compared to data for the most recent previous sampling event showed increases in 
total VOCs in wells MW‐3, MW‐6, MW‐7, MW‐20 and MW‐21, while decreases were seen in 
wells MW‐1R, MW‐5, MW‐8, MW‐10, MW‐12, MW‐19 and MW‐23.  The increase in well MW‐
6 appeared significant, showing an increase from 45 to 10,282 µg/L in total VOCs.  Changes in 
total VOC concentrations within select wells are shown below: 

Changes in total VOC concentrations wells may relate to groundwater fluctuations allowing 
“liberation” of targeted contaminants within the soils in and near the area excavated in April/May 
2008.  While current data do show fluctuation, these data are not thought to represent expansion 
of the contaminant plume.  Laboratory results are included in Table B‐4 and shown on Figure 4.  
An estimate of groundwater benzene contamination related to the release at the site is shown on 
Figure 5.  The laboratory report is included in Appendix A.

D.2. SUPPLY WELL SAMPLING – JANUARY 2023 

WR personnel purged and sampled non‐potable supply well WSW‐1 on January 10, 2023.   

Well Purging / Supply Well Sampling 
By way of purging, the pump within the well was energized and allowed to operate continuously 
for no less than 10‐miuntes time.  Following purging, samples were obtained from the well through 
decanting directly from the sampling point into laboratory‐prepared sample containers holding 
appropriate preservative(s) as required.  Groundwater samples were submitted to Waypoint for 
analysis by SM6200B (VOCs).   

Laboratory Results 
Laboratory Results associated with sampling of supply well WSW‐1 showed naphthalene present 
at a concentration of 2.54 µg/L.  This concentration does not exceed the 2L Standard for the 
compound.  No other compounds were reported in the sample at levels above the laboratory MDL.  
Laboratory results are included in Table B‐4 and the laboratory report included in Appendix A.

SECTION E.  CONCLUSIONS AND RECOMMENDATIONS 

This report documents the results of field activities conducted at the site for TA‐04, which included 
the gauging, purging and sampling of site monitoring wells and supply well WSW‐1.  Conclusions 
based on observations, analytical data and research relating to the release at the site combined 
with historical information include the following: 

• The site is currently used as a retail thrift store and consignment shop. 
• Potable water is available to the site and surrounding properties through the Moore County 
Water Department, East Moore Water District (PWS ID NC50‐63‐011).   
• One active potable supply well (WSW‐8) was found to lie within 500‐ft of the source location.  
WR petitioned the owner of WSW‐8 to allow for the installation of a water line connection 
followed by abandonment of the well, but the owner has been non‐responsive.   
• Three additional active, potable wells (WSW‐3, WSW‐7 and WSW‐14) were identified 
between 500‐ and 1,000‐ft of the source area. 
• Two active, potable wells (WSW‐5 and WSW‐13) were identified between 1,000‐ and 1,500‐
ft of the source area. 
• Two non‐potable or inactive supply wells (WSW‐2 and WSW‐4) were found to lie within 500‐
ft of the source location. 
• An additional seven non‐potable or inactive supply wells (WSW‐1A, WSW‐1B, WSW‐6, 
WSW‐9, WSW‐10, WSW‐11 and WSW‐12) were identified between 500‐ and 1,000‐ft of the 
source area.   
• The NCDEQ Source Water Assessment Program (SWAP) does not list any surface water 
intakes, wellhead protection areas or community supply wells within a 1‐mile radius of the 
source area.   
• The nearest listed wellhead protection area is located approximately 3‐miles east of the site, 
on the eastern side of Aurora, NC.   
• The National Wetlands Inventory, administered by the U.S. Fish and Wildlife Service identifies 
the following features in proximity to the source location: 

o A Freshwater Pond Habitat approaching to within approximately 345‐ft southeast of the 
source area.  
o A Freshwater Pond Habitat approaching to within approximately 625‐ft north.  
o A Freshwater Forested Shrub Wetland approaching to within approximately 580‐ft south.  
o A Riverine Habitat approximately 827 ft north 
o A Freshwater Forested/Shrub wetland approximately 910 ft northwest of the source area.   

• The 1985 Geologic Map indicates that the site is situated within the Middendorf Formation of 
the Coastal Plain Physiographic Province.   
• The site is located within the western portion of the Coastal Plain Physiographic Province of 
North Carolina (Coastal Plain) in a location in which movement of surficial groundwater to 
deeper water‐bearing formations of underlying aquifers may occur.   
• Installation and sampling of Type III monitoring wells MW‐14D, MW‐16D and MW‐18D have 
not shown impact by petroleum contaminants, to date.  This implies that deeper water bearing 
aquifers beneath the site have not been impacted by the release on the property.

Former Black’s Grocery WR Project # 02172214.16 
Monitoring Report February 2023 
16 

 Laboratory analytical results for groundwater samples obtained from site monitoring wells in 
January 2023 showed one or more target compounds in samples from monitoring wells MW‐
1R, MW‐3, MW‐4, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9, MW‐12, MW‐15, MW‐19, MW‐21 
and MW‐23 at concentrations exceeding their respective 2L Standards.  
 No compounds were reported in any samples at concentrations exceeding their GCLs.  
Notably, benzene had been reported in MW‐12 at a level above the GCL in January 2022.  The 
presence of benzene in the well deceased by 18% over the January 2022 – January 2023 
period.   
 Based on the current analytical results and those from previous sampling events conducted at 
the site, the lateral extent of groundwater contamination in the surficial aquifer has not been 
defined to the west of MW‐23, located to the northwest of the source area.  Minor data gaps 
exist to the south and east of MW‐19 MW‐21.   
 Results for analysis of groundwater samples obtained in January 2023 compared to data for 
the most recent previous sampling event showed increases in total VOCs in wells MW‐3, MW‐
6, MW‐7, MW‐20 and MW‐21, while decreases were seen in wells MW‐1R, MW‐5, MW‐8, 
MW‐10, MW‐12, MW‐19 and MW‐23.  The increase in well MW‐6 appeared significant, 
showing an increase from 45 to 10,282 µg/L in total VOCs.  

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

 Performance of chemical amendment injection in the vicinity of wells MW‐5 and MW‐6 as a 
means to reduce contaminant concentrations to levels beneath GCLs.   
 Continued annual groundwater and supply well monitoring at the site to map contaminant 
trends.  
 Based on current groundwater data and site risk, perform additional assessment to the western 
and southern areas of groundwater impact. 

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. 

Cordially, 
WithersRavenel

Client: Withers & Ravenel CASE NARRATIVE
Project: Blacks Grocery Lab Report Number: 23-012-0030
Date: 1/27/2023
Volatile Organic Compounds - GC/MS Method 6200B Analyte: 1,2,3-Trichlorobenzene QC Batch No: V29073/V29072
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable.
Analyte: 1,2-Dibromo-3-chloropropane QC Batch No: V29119/V29072
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: Ethanol QC Batch No: V29073/V29072
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: Naphthalene QC Batch No: V29119/V29072
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.

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.
