2.0 INTRODUCTION 

On behalf of Colvard Oil Company, Pyramid Environmental & Engineering P.C. (Pyramid) 
has completed the Phase II Limited Site Assessment (LSA II) for the former C&H Shell 
(Colvard Oil Co. Office) property. The subject property is located at 317  S. Jefferson 
Avenue in West Jefferson, Ashe County, North Carolina. The location of the site is shown 
on Figure 1, portions of the Jefferson, NC, USGS topographic map.

Pyramid Project # 2021‐080  01/13/2023 
Two 1,000‐gallon gasoline Underground Storage Tanks (USTs) and one 3,000‐gallon 
diesel UST were installed on the property in 1972 and used until 2010. Two 1,000‐gallon 
diesel and one 550‐gallon kerosene USTs were installed on the property in 1985 and 
used until 2010. An orphaned 1,000‐gallon gasoline UST was found during the UST tank 
removal and the dates of use are unknown. During November 4 ‐ 6, 2020, Pyramid 
supervised the removal and permanent closure of the seven USTs. During the UST 
removals in 2020, petroleum releases from the four gasoline USTs were confirmed, and 
were reported to the NC Department of Environmental Quality (DEQ).  The former 
locations of the USTs are shown on Figure 2.

Pyramid Project # 2021‐080  01/13/2023 
3.2 Soil Assessment & UST Closure Activities Summary 
On November 4 ‐ 6, 2020, Pyramid supervised the removal and permanent closure of 
three (3) 1,000‐gallon gasoline underground storage tanks (USTs), one (1) 3,000‐gallon 
gasoline UST, two (2) 1,000‐gallon diesel UST, and one 550‐gallon diesel UST at the C&H 
Shell site.  As part of the permanent closure of the UST systems and Initial Abatement 
Actions, 51.5 tons of petroleum‐impacted soil were excavated and transported off‐site 
for proper treatment and disposal. 

The soil samples collected beneath the three gasoline USTs contained concentrations of 
GRO and DRO that exceed the current NCDEQ initial cleanup levels for GRO of 50 
milligrams per kilogram (mg/kg), and DRO of 100 mg/kg. The laboratory results for the 
product line and dispenser soil samples detected TPH concentrations that exceed the 
current DEQ initial cleanup levels. The locations of the initial UST closure samples are 
shown on Figure 3, and the laboratory results are summarized in Table 2.  

The soil samples collected beneath the two diesel USTs, did not contain concentrations 
of GRO and DRO that exceed the current NCDEQ initial cleanup levels for GRO of 50 
milligrams per kilogram (mg/kg), and DRO of 100 mg/kg. 

The Soil samples collected beneath the kerosene UST, did not contain concentrations of 
GRO and DRO that exceed the current NCDEQ initial cleanup levels for GRO of 50 
milligrams per kilogram (mg/kg), and DRO of 100 mg/kg. 

The contaminated soil above, around, and below the gasoline, diesel, and kerosene 
tanks was excavated.  Most of the petroleum‐impacted soil detected around USTs were 
excavated.  The soil excavations are shown on Figure 3.  The final excavation 
dimensions, sample depths, and sample locations are shown on Figure 3.  The post‐
excavation soil samples for the gasoline excavation were analyzed for volatile organic 
compounds (VOCs) using EPA Method 8260/5035.  

A shown in Table 3 and Table 4, some the targeted risk‐based parameters were 
detected at concentrations that exceed the soil‐to‐groundwater maximum soil 
contaminant concentrations (MSCCs). The results were below residential MSCCs in the 
gasoline post‐excavation soil samples. 

Based on the remaining soil contaminants, and the shallow groundwater at the site, the 
NC DEQ issued a Notice of Regulatory Requirements to Colvard Oil. The DEQ letter 
required the preparation and submittal of a Limited Site Assessment Report for 
regulatory Incident # 47247. The NCDEQ letter dated August 25, 2021 is presented as 
Appendix A.

4.0 RISK CHARACTERIZATION 

The LSA Risk Classification and Land Use Form was completed by Pyramid and is 
presented as Appendix B.  The receptors survey located one active municipal water 
supply well (Well 7A) within 1,000 feet of the former gasoline and diesel UST systems.  
The area is supplied with drinking water by drilled water supply wells operated by the 
town of West Jefferson, and some uphill up‐gradient spring‐fed water supply sources 
operated by the Town as well. Pyramid did not observe any private water supply wells 
during the receptor survey.  The results of the LSA indicate that the incident should be 
classified as “high‐risk” since there is an active water supply well located within 1,000 
feet of the source area.  

5.0 RECEPTOR INFORMATION 

In 2022, Pyramid completed a receptor survey for the former C&H Shell. The site is 
located in downtown West Jefferson, where all properties within 1,500 feet use 
municipal water provided by the Town of West Jefferson. Pyramid completed the 
receptor survey in May 2019 by walking and interviewing some of the property owners 
located within 1,000 feet of the site.  The surrounding area is shown on Figure 4. The 
property owner and supply well information for the properties within approximately 
1,000 feet are provided in Table 5.  

A search for supply wells found only one municipal water supply well location within 
1,000 feet of the site, as shown on Figure 4.  

5.1 Water Supply Wells: 
As shown on Figure 4, no private water supply wells and springs were identified within 
1,000 feet of the site. One public water supply well (MW‐7A is located approximately 
950 feet to the northwest and is shown on Figure 4.  

5.2 Public Water Supplies are Not Available  
The subject site and all properties within 1,500 feet of the site rely on the Town of West 
Jefferson for potable water supply.

Pyramid Project # 2021‐080  01/13/2023 
5.3 Surface Water: 
The nearest surface water is Little Buffalo Creek, which is located under the site.  The 
surface water run‐off on the subject site generally flows to the east towards Little 
Buffalo Creek.   

5.4 Wellhead Protection Areas: 
The area surrounding the site is within the West Jefferson designated wellhead 
protection area. 

5.5 Deep Aquifers in the Coastal Plain Physiographic Region: 
This site is not in the Coastal Plain; therefore, this section does not apply to this site. 

5.6 Subsurface Structures: 
The culvert for stormwater beneath the site is the only known subsurface structure 
located in the source areas. 

5.7 Land Use: 
The area near the subject site is primarily commercial and industrial properties with 
some nearby residential properties. The nearest residential properties are 
approximately 430 feet to the east southeast. 

6.0 SITE GEOLOGY AND HYDROGEOLOGY 

Pyramid’s review of the 1985 Geologic Map of North Carolina yielded information 
concerning local geology and hydrogeology. Based on this review, the site is in the Blue 
Ridge Belt of North Carolina. The surface geology consists of regional soils created by 
the weathering of the underlying bedrock. According to the 1985 Geologic Map of North 
Carolina, the underlying bedrock beneath the site includes Equigranular, massive to well 
foliated, interlayered, rarely discordant, metamorphosed intrusive and extrusive mafic 
rock, map symbol Zata. 

In general, both surface and groundwater flow directions are controlled by topographic 
contours of landforms, with flow occurring perpendicular to the contours from high to 
low elevations. At the C&H Shell Site, there is a box culvert which contains an active 
surface water stream. The on‐site stream flows about 0.5 miles into Little Buffalo Creek, 
Surface water from the subject enters the storm drains and flows northeast into Little 
Buffalo Creek which is shown in Figure 1.

7.0 GROUNDWATER INVESTIGATION 

7.1 Monitoring Well Installation: 
To investigate groundwater in the three UST system areas, Pyramid installed three 2‐
inch diameter monitoring wells on October 12, 2022.  The wells (MW‐1, MW‐2 and MW‐
3) were installed to a depth of 15 feet BLS.  The MWs were drilled using a truck‐
mounted drill rig and installed with solid stem augers. The wells were constructed using 
10 feet of 2‐inch diameter schedule‐40 PVC 0.010‐inch slotted screen, and the 
remaining portion was constructed of schedule 40 PVC solid well casing.   

Monitoring wells MW‐1 was installed downgradient of the former dispenser island and 
MW‐2 was installed near the former 3,000‐gallon gasoline UST. Monitoring well MW‐3 
was installed next to the two former 1,000‐gallon diesel USTs on the downgradient side 
of the site. The location of the monitoring wells are shown on Figure 2.  The well 
construction data for the monitoring wells are included in Table 6, and a copy of the 
well construction records and soil boring logs are presented in Appendix C.  

During the installation of each monitoring well, soil samples were screened in the field. 
The soil sample with the highest PID reading from each well was collected for risked‐
based laboratory analyses.  The laboratory results for soil sample MW‐1(5‐6’) and MW‐
2(5‐6’) detected some of the targeted risk‐based parameters above soil‐to‐groundwater 
MSCC levels but below residential MSCCs.  NO Soil samples were collected for Risk‐
Based analyses from MW‐3 since the GRO and DRO concentrations in that area were 
below cleanup levels.  The laboratory results are summarized in Table 7. The soil sample 
laboratory report is included in Appendix D. 

7.2 Monitoring Well and Supply Well Sampling & Laboratory Analyses: 
On October 13, 2022, groundwater samples were collected from monitoring wells MW‐
1, MW‐2 and MW‐3 for laboratory analyses. Prior to collecting the groundwater 
samples, the monitoring wells were gauged to record the depth to groundwater and 
check for free product. No free product was detected in any of the monitoring wells.  
The depth to groundwater ranged from 7.36 to 7.71 feet below the top‐of‐casing (TOC). 
The site is in a river valley and the groundwater is shallow.  

To purge stagnant water and develop each monitoring well, approximately 2 to 4  
gallons of water was removed from each well using disposal bailers. The standard field 
procedures used by Pyramid are summarized in Appendix D.  The groundwater samples 
were collected using the disposable bailer and placed in laboratory prepared containers, 
packed in ice, and prepared for shipment to Pace Analytical Services in Huntersville, NC.  

Colvard Oil Company, Inc. – C&H Shell –  Limited Site Assessment (LSA II) 7 
Pyramid Project # 2021‐080  01/13/2023 

The groundwater samples from monitoring wells MW‐1, MW‐2, and MW‐3 (from the 
gasoline area) were collected for gasoline methods, and analyses included EPA Method 
6200B for volatile organic compounds (VOCs),  Method 504.1 for 1,2‐Dibromomethane 
(EDB), and EPA Method 6010 for lead (Pb).  All groundwater concentrations are 
reported in Micrograms per liter (µg/l). 

7.3 Groundwater Flow Direction 
On October 13, 2022, Pyramid conducted an elevation survey to establish the relative 
top of casing (TOC) elevations for the groundwater monitoring wells. Groundwater 
elevation data recorded in the field was used with the relative elevation survey data 
from the monitoring wells to calculate the relative groundwater elevation for each well.  
The TOC elevation data from the survey and depth‐to‐groundwater measurements are 
presented on Table 8 with the calculated groundwater elevation at each MW.   

Utilizing the calculated relative groundwater elevation data for the Type II monitoring 
wells, a potentiometric surface map was prepared for the site and is presented as Figure 
5.  The groundwater contours show groundwater flow to the northeast with the surface 
water stream toward Little Buffalo Creek. This flow direction concurs with the local 
topography and stream flow. No Free‐Product was found in any of the MWs. 

7.4 Groundwater Analytical Results: 
The laboratory results of the groundwater sample collected from MW‐1 on October 13, 
2022 showed concentrations of benzene at 11.9 micrograms per liter (ug/L). The 
benzene concentration in MW‐1 is above the North Carolina Administrative Code 
(NCAC) 2L Groundwater Standard for benzene and just greater than 10 times the 
drinking water standard. The remaining wells did not have any compounds above the 
NCAC  2L groundwater standards.  

The laboratory results for the groundwater samples collected in October 2022 are 
summarized on Table 9, and a copy of the laboratory report and chain of custody is 
presented as Appendix E.  Groundwater concentration contours were prepared for 
BTEX compounds and MTBE and are presented as Figures 6‐10, respectively. These 
analytical data and concentration contours show a relatively small area of benzene 
concentrations above NCAC 2L groundwater standards. Naphthalene and n‐
butylbenzene were slightly above the NCAC 2L standard but well below NC Gross 
Contaminant Limits (GCLs).

Pyramid Project # 2021‐080  01/13/2023 
8.0 ASSESSMENT SUMMARY 

As requested by Colvard Oil Company, Inc., Pyramid has completed the Phase II Limited 
Site Assessment (LSA II) for the former C&H Shell in West Jefferson, NC.  A summary of 
the assessment results is presented below. 

 In November 2020, Pyramid supervised the removal of the former C&H Shell 
gasoline UST systems, diesel USTs, kerosene UST, and associated product piping. 

 On November 4, 2020, approximately 20 gallons of dark gasoline free‐product was 
vacuumed from beneath the Orphaned gasoline UST excavation. The free‐product 
was a dark, old gasoline, and did not return to the excavation after it was pumped 
out once. To further remediation the pump island area, this area was excavated on 
November 5th, and approximately 12.56 tons petroleum contaminated soil was 
removed from the bottom of the pump island/gasoline tank excavation.  

 Approximately 51.5 tons of petroleum contaminated soil was removed from the site 
during the UST removal process.  

 On October 12, Pyramid installed three groundwater monitoring wells (MW‐1, MW‐
2, and MW‐3) in the three source areas at the site.  

 Risk‐based soil analytical results showed Benzene in MW‐1 and MW‐2 at levels 
which exceed the soil‐to‐groundwater MSCCS but are below the residential MSCCs.  

 Risk‐based soil analytical results showed Tetrachloroethene in MW‐3 at levels which 
exceed the soil‐to‐groundwater MSCCS but are below the residential MSCCs. 

 The water table at the site is between 7.36 and 7.71 feet BLS.  

 The receptors survey showed that all developed properties within 1,000 feet of the 
site rely on the Town of West Jefferson for water supply. One public water supply 
well (MW‐7A) is located approximately 950 feet to the northwest of the site. 

 The nearest surface water is a tributary to Little Buffalo Creek. The tributary runs 
beneath the site in a box culvert. The nearest surface water is at the site.   

 The risk classification of the incident should be “High Risk”. 

Based on the findings of this LSA II, the concentrations detected in the monitoring wells 
are relatively low and do not pose an imminent threat to any supply well. Additional 
monitoring and groundwater assessment is recommended.   

Colvard Oil Company, Inc. – C&H Shell –  Limited Site Assessment (LSA II) 9 
Pyramid Project # 2021‐080  01/13/2023 

9.0 RECOMMENDATIONS 

As requested by Colvard Oil Company, Pyramid completed the LSA II and risk evaluation 
for the C&H Shell in West Jefferson, NC. Based on the findings and evaluation of the 
assessment data, Pyramid recommends the following: 

 Installation of one additional groundwater monitoring well to the northwest of 
MW‐1 to define the groundwater concentrations of benzene at the site. This well 
will be installed and surveyed to provide a relative TOC elevation. 

 After the proposed MW is installed, we recommend gauging all wells and 
collecting a full round of groundwater samples from all MWs.

Standard Field Procedures
Pyramid Environmental & Engineering, P.C.
________________________________________________________________________

1.0 Equipment Decontamination

Equipment decontamination is essential to assure representative environmental samples 
are collected and to eliminate the potential for cross‐contamination between sample points. 
Pyramid strives to clean all field equipment prior to leaving the office; however, field 
decontamination is still required on most projects. The procedures for decontamination of 
water level probes, hand augers, sampling probes, trowels, and other field equipment are 
listed below. 

1.1 EPA Region IV Decontamination Procedures  
Drilling and soil sampling equipment is decontaminated prior to each use using a pressure 
washer or steam cleaner. Reusable sampling equipment (hand augers, sampling probes, 
trowels, split spoon samplers, water sampling equipment, etc.…) are decontaminated using 
the general procedure described below.  
 Wash with non‐phosphate detergent, water, & brush to remove particulate matter 
 Rinse with tap water 
 Rinse with 10 percent nitric acid solution (only if sampling for metals) 
 Rinse with de‐ionized water 
 Rinse with pesticide‐grade isopropyl alcohol 
 Rinse with de‐ionized water 
 Air‐dry as long as possible  
The level of decontamination used is appropriate to the analytical parameters selected and 
the material of the sampling device being used for sampling. For example, if metals analyses 
are required, then the 10 % nitric acid solution is used for decontamination of stainless‐steel 
equipment. Pyramid uses de‐ionized or distilled water for decontamination. Equipment that 
is not used immediately after decontamination is wrapped in aluminum foil prior to storage. 

2.0 Soil Borings & Sampling
2.1 Soil Borings  
Soil borings are used by Pyramid to investigate and characterize the subsurface at sites.      
Soil borings provide information concerning soil types and density, depth to refusal, depth 
to bedrock, organic vapors that may be present, and can be used to obtain samples for 
laboratory analysis.  
Standard Field Procedures:  Revision 10.6                            Page 2 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
Pyramid conducts borings in several different ways, using hand augers, direct‐push 
equipment (Geoprobe), sample probes, split‐spoon samplers (ASTM D 1586‐84), auger 
drilling, air drilling, and Vibro‐Core. The following procedures are used by Pyramid 
Environmental when performing soil borings:  
1. Soil boring locations are chosen, and the ULOCO utility locating service is called to 
mark all public utilities. Pyramid locates private utilities at many project sites using 
Pyramid locating equipment, or uses a private utility locating service. 

2. Down hole drilling equipment is cleaned prior to use and between borings using 
pressure washing or steam cleaning. Additional decontamination procedures in 
Section 1.1 are used for sampling tools such as split spoons or direct‐push points.  

3. Soil borings are advanced using direct‐push, drilling rigs, hand augers, or other 
appropriate means. Near‐surface soil samples may also be collected using stainless 
steel push probes, shovels, scoops, or other sampling devices.  

4. Soil samples are normally collected at a minimum of 5‐foot intervals. Each sample is 
divided into two parts. Soil samples for laboratory analyses are jarred from the initial 
sample volume. The remaining soil is stored in a sealed container for headspace 
analysis and geological description.  

5. After screening the soil with the field instruments, each soil sample is described by 
the field geologist and a geologic description is recorded in project documentation. 

6. Soils are typically described in the field by the project geologist or soil scientist and 
are classified according to the Unified Soil Classification System (ASTM D 2488‐84). 

7. Soil samples selected for laboratory analysis are placed in properly prepared, 
laboratory supplied containers and immediately packed in a cooler on ice. Sample 
custody is maintained using standard chain‐of‐custody (COC) procedures through 
delivery to the analytical laboratory. 

8. Soil borings, which are not completed as monitoring wells, are grouted using a 
Portland cement, bentonite, or backfilled with soil cuttings.  

9. Soil cuttings are generally spread near the soil boring or monitoring well location as 
directed by State regulatory managers.  Drill cuttings are drummed (containerized) 
where site conditions or regulatory requirements prohibit spreading cuttings, and 
are disposed off‐site (after waste determination is made).  

Standard Field Procedures:  Revision 10.6                            Page 3 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
2.2 Soil Headspace Screening  
Soil samples are routinely screened for volatile organic compounds (VOCs) which may be an 
indication of organic or petroleum hydrocarbon contamination. The typical screening 
procedure includes immediately transferring the soil from the sampling devices to a sealed 
container (sealed 1‐gallon Ziplock plastic bag). The soil container is filled approximately 
halfway with soil and sealed. This creates headspace above the soil in which VOCs may 
accumulate. The container is allowed to stand for 5 to 15 minutes for the VOCs to equilibrate 
in the headspace of the container. The headspace of the container is then screened using a 
calibrated organic vapor analyzer (PID or FID). The screening is conducted by cracking the 
seal only enough to allow insertion of the probe into the headspace so as not to dilute the 
sample. In most cases where the contaminant of concern includes volatile organics, the 
highest or “Peak“ field‐screening result is documented for each sample. The soil samples 
showing the highest reading from each boring are typically selected for laboratory analysis. 

2.3 Soil Sample Collection for Laboratory Analysis   
After the targeted depth has been reached, soil samples are collected using a variety of 
sampling devices. Soil sample devices used include split‐spoons, stainless‐steel hand augers, 
stainless‐steel push‐probes and sampling scoops, and directly from the center of the 
excavator bucket. The sample technician uses disposable nitrile gloves, which are changed 
between samples to avoid cross‐contamination of samples, and each sampling device is 
decontaminated prior to use.  

Only laboratory provided containers are used for sample collection. Samples are collected 
in accordance with the preservation methods required by the requested analytical method. 
Samples are handled as little as possible and preserved in the field as specified for the 
analytical method. The samples are stored and transported to the laboratory in an insulated 
cooler chilled to approximately 4 degrees centigrade. The samples are labeled with a 
minimum of the following information: Pyramid, project name or number, sample 
identification, date collected, sampler name, and analysis requested. Sample custody is 
maintained using standard chain‐of‐custody procedures through delivery to the analytical 
laboratory. Notes of the sampling events are recorded in project documentation. 
Incremental sampling methodology (ISM) is a structured composite sampling and 
processing protocol that reduces data variability and provides a reasonably unbiased 
estimate of mean contaminant concentrations in a volume of soil targeted for sampling. 
ISM provides representative samples of specific soil volumes defined as decision units 
(DUs) by collecting numerous increments of soil (typically 30–100 increments) that are 
combined, processed, and subsampled according to specific protocols. ISM Sampling will 
be further explained in a site‐specific Work Plan documents. 
Pyramid will contract an on‐site laboratory for immediate analyses as needed.

Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
2.4 Sediment Sample Collection for Laboratory Analysis   
Near surface sediment may be present in a surface water ditch, stream, or dry intermittent 
stream bed. Sediment samples are typically soil related samples and may be collected with 
a variety of sampling tools. Pyramid will use stainless‐steel samplers which have been 
decontaminated according to the procedure detailed in section 1.1 of this document. After 
the sediment samples are collected, the location, depth, conditions, and sample 
composition are documented in the project records. The samples will be screened in the 
field to detect volatile organic vapors and visually examined for contamination. Sediment 
samples will be preserved in laboratory prepared containers in accordance with sample 
preservation recommendation of the analytical laboratory. Samples are handled as little as 
possible and preserved in the field as specified for the analytical method. The samples are 
stored and transported in an insulated cooler chilled to approximately 4 degrees centigrade. 
The samples are labeled with a minimum of the following information: Pyramid, project 
name or number, sample identification, date collected, sampler name, and analysis 
requested. Sample custody is maintained using standard chain‐of‐custody procedures 
through delivery to the analytical laboratory. Documentation of the sampling events are 
recorded in the project documentation. 

3.0 Direct-Push Sampling Procedures

Direct‐push sampling techniques have been used at many sites to collect soil and 
groundwater samples rapidly and inexpensively.  Track‐mounted, direct‐push rigs can access 
hard to reach areas and allow borings and monitoring wells to be installed.  For soil sampling, 
typically, the direct‐push steel drive tube is decontaminated using a pressure washer, and a 
new plastic sample liner is inserted in the steel drive tube to collect soil samples. The soil 
samples are collected in new polyethylene sample tubes within the steel drive tube. The soil 
samples are then extracted from the polyethylene liner and preserved as required for 
laboratory analysis. 

For groundwater sampling, a steel probe with a retractable screen section and tubing are 
driven to depth and the screened section is opened to allow groundwater to enter the 
tubing. The water samples are withdrawn using new polyethylene and Teflon® tubing with 
either a decontaminated stainless‐steel check ball, or peristaltic pump. The groundwater 
sample is placed directly into the appropriate laboratory containers and sealed immediately. 
To prevent cross‐contamination of samples, new disposable tubing is used for each 
groundwater sample point. Disposable nitrile gloves are worn by field personnel during 
development and groundwater sampling, and gloves are changed between samples. 
Groundwater sampling procedures are detailed more in Section 5.0, as appropriate for each 
analytical method.

4.0 Monitoring Well Installation

Groundwater monitoring wells are installed in many subsurface environments; Coastal 
Plain, sedimentary, Piedmont saprolite, weathered rock formations, and mountain terrains 
to list a few. Formations encountered include unconsolidated and consolidated sediments, 
fill material, organic soils, saprolitic soils, weathered rock formations, and bedrock. 
Groundwater monitoring wells provide a stable sampling point at discrete intervals within 
the confined or unconfined aquifers. Monitoring wells are installed for a number of reasons, 
and are typically installed as 1‐inch, 2‐inch, 4‐inch, or 6‐inch diameter wells. Construction 
may be of PVC, stainless‐steel, HDPE, or other appropriate materials. The following 
procedures are used by Pyramid when performing borings and monitoring well installations.   If required, monitoring well permits are obtained from the State, County, or City. 
 Boring and monitoring well locations are chosen, and utilities are marked by the 
public utility locating company. As needed, the locations may be scanned for utilities 
by Pyramid using our locating equipment, or a private utility locating company. 
 In selecting a drill site, care is taken to avoid overhead power lines, and subsurface 
utilities whenever possible. 
 Down‐hole drilling equipment is decontaminated prior to use and between borings. 
 Borings are advanced using direct‐push, drilling rigs, hand augers, solid‐stem augers, 
hollow‐stem augers, air rotary drilling, or air hammer drilling. 
 Soil samples are normally collected at a minimum of 5‐foot intervals. Each sample is 
divided into two parts.  Soil samples for laboratory analyses are jarred from the initial 
sample volume. The remaining soil is stored in a sealed container for headspace 
analysis with an organic vapor analyzer (PID or FID).  
 After screening the soil with the field instruments, each soil sample is described by 
the field geologist and a geologic description is recorded in the project 
documentation. 

Type II monitoring wells are usually installed using 2‐inch diameter schedule 40 PVC riser 
and 2‐inch, 0.010‐inch machine slotted well screen. The screened interval length varies with 
the geologic site conditions, expected variations in water level, and the investigation goals 
for the well. The well construction details are presented on the boring log. 

Type III wells are usually installed as double‐cased wells to monitor the deeper portions of 
the aquifer. The first casing is usually a 5 to 6‐inch diameter solid PVC well casing drilled to 
bedrock or an appropriate depth within the surficial zone. The 5 to 6‐inch diameter casing 
is then set and grouted in the borehole. After the cement grout has set for 12 to 24‐hours, 
the borehole is completed to the desired depth using air rotary drilling or air hammer 
drilling. The inside casing of the Type III monitoring well is usually constructed of 2‐inch 
diameter SCH 40 PVC casing and 2‐inch diameter SCH 40 PVC 0.010‐inch slotted well screen. 

Standard Field Procedures:  Revision 10.6                            Page 6 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
In most applications, a sand filter pack of #2 well sand (or appropriately sized well sand).  
Sand is typically installed to a level of 2 feet above the top of the screen in each well.                   
A minimum 2‐foot thick bentonite seal is usually placed on top of the filter pack and 
hydrated with de‐ionized or distilled water. The remaining annular space of a typical well is 
backfilled to grade with a Portland cement/bentonite grout. In monitoring wells where the 
water table is close to surface, the amount of sand above the screen and bentonite will be 
reduced to allow for a minimum of 2–3 feet of cement grout in the well bore. 

At the surface, each well is secured with a locking cap and a steel well protector. Depending 
on the surface conditions, the well may be protected by a flush‐mounted manhole set in the 
surrounding surface in a concrete pad.  In some cases, stick‐up well protectors are used to 
secure the well and allow the well to be more easily located in wooded or open areas. 

Each groundwater monitoring well is developed by surging, pumping, or bailing to remove 
sediment before sampling. Water removed during development is managed according to 
individual State regulatory guidance. 

5.0 Water Sampling Procedures

Pyramid relies on water sampling as a primary method for assessment of subsurface 
groundwater conditions. Water sampling typically includes sampling groundwater from 
monitoring wells, water supply wells, surface water bodies, stormwater,  waste sumps, etc.   
The following provides typical sampling procedures for the water samples. 

5.1 Monitoring Wells  
Prior to sampling each monitoring well, depth to liquid and/or liquids and total well depth 
are measured using a properly decontaminated electric interface probe. If phase‐separated 
petroleum product is detected in a well, the product measurements are recorded along with 
the water level in each well.  This information is recorded in the field record and the volume 
of the water in the well casing is calculated. To purge stagnant water from each monitoring 
well, three to five well casing volumes of water are removed from each well prior to 
sampling. Alternately, for low‐flow sampling, development continues until the field 
parameters (pH, conductivity, dissolved oxygen, ORP, and temperature) have stabilized.   
If the water in the monitoring well is removed until the well is dry, then the well is sampled 
thereafter. Water removed from wells during purging is managed in accordance with 
individual State regulatory guidance.  

Groundwater samples are typically collected using a new disposable polyethylene bailer and 
a new length of nylon cord. To prevent cross‐contamination of samples between wells, a 
new disposable bailer is used for each well.  The bailer is lowered into the groundwater 
Standard Field Procedures:  Revision 10.6                            Page 7 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
slowly and removed slowly.  A new pair of disposable gloves is worn by field personnel 
during purging and sampling, and is changed between wells.  In the case of small diameter 
monitoring wells or direct‐push water samples, water samples may be collected using a 
peristaltic pump and new polyethylene tubing.  Another method is to use a segment of new 
sampling tubing and a stainless‐steel check ball to create a “Tube Bailer”.  
Groundwater samples selected for laboratory analysis are immediately placed in properly 
prepared, laboratory supplied containers and preserved in a cooler on ice. Samples are 
maintained under standard chain‐of‐custody procedures from sample collection through 
laboratory analysis. 

5.2 Water Supply Well Sampling  
Prior to sampling each water supply well, the well owner is contacted to provide access to 
the well. The well owner is interviewed to locate the faucet closest to the well for sampling.    
If there are no faucets located on the well, then water from an outside faucet at the building  
is usually sampled. If there are no outside faucets available, then the water samples are 
collected from an inside faucet. The location of the sample is recorded in the field record.  
The owner is interviewed to see if there is a chlorination system on the well, or if the well 
has been recently chlorinated. Recent chlorination could affect the laboratory detection 
limits. In most cases, the samples are preserved using sodium thiosulfate or ascorbic acid to 
remove the interactions of chlorine, which may be present in the samples.   
If the well is treated with a Point‐of‐Entry (POE) treatment system, then the “raw” water 
sample must be collected before the treatment system. An associated treated water sample 
is usually collected as well to demonstrate effective treatment.    
To purge stagnant water from the water supply well system, the faucet is allowed to run on 
full stream for a minimum of 15 minutes. The aerator is removed from the tap if one is 
present. Water removed from wells during purging is managed according to regulatory 
standards.  
Water supply well samples are collected using appropriate laboratory prepared containers 
for each analysis.  The analytical methods selected will vary with the contaminant of 
interest. To prevent cross‐contamination of samples between wells, disposable nitrile gloves 
are worn by field personnel during purging and sampling and are changed between wells. It 
is possible that samples may be required at several places within the water supply system. 
The samples are collected accordingly and labeled to show the source and location sampled.  
Supply well samples selected for laboratory analysis are immediately placed in properly 
prepared, laboratory supplied containers and packed in a cooler on ice, and chilled to 
approximately 4 degrees Celsius.  Samples are maintained under standard chain‐of‐custody 
procedures from sample collection through laboratory analysis. 

Standard Field Procedures:  Revision 10.6                            Page 8 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
5.3 Surface Water Sampling  
Surface water samples are obtained using several techniques including use of sample 
bailers, discrete depth interval samples, sample scoops, from boats, bridges, or wading into 
a stream. Caution should always be used when sampling surface water to ensure that the 
water collected is representative of the site conditions. Since stream or open water sampling 
is transient, careful documentation of the site conditions, weather, surface conditions, 
sediment, algal or biological material, etc. is required.  

In many studies, additional samples from upstream and downstream of the desired sample 
point are required. Surface water sampling must be planned to reflect the site‐specific 
conditions during sampling. The general procedures are similar to the supply well sampling 
procedures detailed above. Appropriate laboratory prepared containers are used for each 
analysis. The analytical methods selected will vary with the contaminant of interest. 

To prevent cross‐contamination of samples between samples, disposable nitrile gloves are 
worn by field personnel during purging and sampling and are changed between samples. It 
is possible that samples may be required at several places along the stream to check for 
influences of up‐stream facilities.  Samples will be collected accordingly and labeled to show 
the source and location sampled. Sample will always be collected upstream of the area 
disturbed by the person sampling the stream. Surface water samples selected for laboratory 
analysis are placed in properly prepared, laboratory supplied containers and immediately 
packed in a cooler on ice. Samples are maintained under strict control using standard chain‐
of‐custody procedures through laboratory analysis.  

6.0 Quality Assurance / Quality Control

The field and laboratory procedures listed above have been implemented on many sites 
with excellent results. The procedures are often verified by an appropriate use of the 
following environmental samples. 

Trip Blanks ( or Travel blanks) 
The Trip Blank (or travel blanks) are often used to verify that the environmental samples are 
not impacted during shipping, and verify that the source of the glassware is not the source 
of contamination. The trip blanks are preserved de‐ionized water, collected in the 
laboratory, and shipped with the sample containers to Pyramid or the site. The trip blank 
remains in the sample cooler and is shipped back to the laboratory with the environmental 
samples. The trip blank is most commonly analyzed for volatile organic compounds (VOCs), 
and correspond to the target analyses. 

Standard Field Procedures:  Revision 10.6                            Page 9 
Pyramid Environmental & Engineering, P.C.           Revision date 01‐06‐2020 
Field Blanks  
Field Blanks are quality assurance samples which are collected in the field to represent the 
conditions present at the time the samples are collected. For water samples, the laboratory 
containers are opened and filled in the field using de‐ionized (or distilled) water from a 
known source.  The samples reflect any site conditions such as vapor sources which may 
affect the water samples.  The samples then travel to the laboratory with the other samples 
for analysis. Comparison of the field blank results with the sample results may indicate a 
pervasive site constituent detected in the samples.  

Equipment Blanks  
Equipment Blanks are used to verify whether the decontamination procedures used for the 
sample equipment (or the new equipment) may have added any contaminants to the 
sample during collection. If a non‐disposable sampling device is used (such as a sampling 
treir, scoop, hand auger, Teflon bailer, etc.…), then the decontamination of the sampling 
device is usually verified using an equipment blank. The equipment blank is collected using 
de‐ionized (or distilled) water from a known source. The equipment is decontaminated,  
allowed to air dry, the water is poured over (or through) the equipment, and a sample is 
collected in the appropriate sample containers. The equipment blank samples are preserved 
with the other environmental samples, and shipped for analyses for the target parameters. 

Duplicate Samples 
Duplicate Samples are used to verify the sampling procedures and evaluate laboratory 
analysis variability. The duplicate samples may be collected from soil, sediment, air, surface 
water, wastes, or groundwater. These samples are collected and sent to the laboratory as  
blind samples to have maximum effectiveness. Duplicate samples are generally analyzed for 
the same analytical methods as the actual environmental sample for direct comparison. 
Duplicate samples may also be split between two different laboratories to provide 
verification of laboratory detection limits or quality process verification. 

Background Samples 
Background Samples are a tool for comparison of general site conditions with source area 
site conditions. Background samples may be soil, sediment, air, surface water, waste, or 
groundwater. The goal is to reflect conditions outside the expected area of contamination. 
These samples are collected outside the expected area of contamination and sent to the 
laboratory for analyses. Background samples are generally analyzed for the same analytical 
methods as the source area environmental samples for direct comparison. Background 
samples for metals comparison are common types of background samples used in 
environmental investigations.
