1.0 INTRODUCTION
The site is the Speedway Store 6959 located at 2808 US Highway 70 Business East
in Clayton, North Carolina (Drawing 1.1). The site is a petroleum retail facility and
convenience store and contains four 10,000-gallon capacity USTs (diesel, premium
gasoline, midgrade gasoline, and regular gasoline) and one 2,000-gallon capacity
kerosene UST. The USTs are reportedly constructed of fiberglass and were installed in
January of 1998. A site drawing with the approximate locations of the USTs is presented
as Drawing 1.2.
On November 1, 2015, a customer at the station observed fuel spilling out the top of
a vent pipe at the site. The system was immediately shut down and Jones & Frank
Corporation (Jones & Frank) was called to the site to investigate the problem. They found
that the regular unleaded #2 UST (the 10,000-gallon capacity regular unleaded tank) had
been filled to more than 90% of the capacity of the tank. Trade Wilco reportedly delivered
fuel to the tank the prior day around noon. The overfilling resulted in fuel spilling out
the top of the vent line for this tank when the pump was activated. The vent lines are
located in a grassy area immediately adjacent to, and west of, the kerosene dispenser. It
is unknown how much fuel was released. Fuel was also present in the TLS (Tank Level
Sensor) equipment vault that sits over the top of the tank. According to Jones & Frank,
the pressure in the tank forced fuel up through the equipment and into the vault. A small
amount of fuel was also present in the fill port spill bucket, but Jones & Frank personnel
believe that this fuel was the result of spillage at delivery.
On November 12, 2015, soil excavation was performed in the area of the vent pipes.
Petroleum-impacted soil was excavated to the tops of the fiberglass vent pipes starting
near the vent pipe vertical risers, extending approximately 8 feet along the pipes and
approximately 6 feet wide. Highly impacted soil and pea gravel remained directly below
the vent pipes and contamination did not appear to have migrated much past the sides
of the pipe trenches. Six soil samples were collected and analyzed for TPH-GRO. These
analytical results confirmed the release of petroleum to the soils.
Based on site data, a Phase I LSA was performed, as well as the installation of two
vapor recovery points and completion of an AFVR. During the Phase I LSA, Mid-Atlantic
Associates (Mid-Atlantic) installed one monitoring well (MW-1) within the grassy area in
the immediate proximity of the vent pipes. Sampling results indicated petroleum target
compound concentrations greater than 10 times the North Carolina Groundwater Quality
Standards (NCGQS). A receptor survey was also conducted during the Phase I LSA
and revealed that water supply wells are in use for drinking within a 1000-foot radius
of the release. A public water supply is not available to the surrounding residences or
businesses. The nearest surface water was determined to be approximately 1,000 feet
from the source area of the release. Based on this information, Mid-Atlantic preformed a
Phase II LSA.
Three additional monitoring wells were installed at the site in an attempt to delineate
groundwater flow and evaluate the extent of soil and groundwater contamination.
Groundwater flow direction was determined to be towards the southeast but later
determined to be towards the southwest. Groundwater collected from MW-1 during the
Phase II LSA exhibited several target compounds at concentrations in excess of their
respective 2L Standards, but below their GCLs. Benzene and toluene were detected
in soil samples collected above their respective Soil-to-Groundwater MSCCs but below
their corresponding Residential MSCCs. An 8-hour AFVR event was performed on
January 7, 2016 in an attempt to remove potential residual free product and provide
remediation of the gravel and surrounding soils. Free product was not detected at the
time of the AFVR event. At the conclusion of the Phase II LSA, it was determined that the
extent of the groundwater contaminant plume had not been defined.
Following submittal of a Phase II Limited Site Assessment Report dated June 21, 2016,
the NCDEQ issued a NORR dated June 23, 2016 requesting the submittal of a CSA
for the site. In an attempt to define the extent of the plume, additional groundwater
monitoring wells have been installed and sampled at the site. Data revealed that high
MTBE concentrations are present in groundwater in well MW-2D, which is screened
at a depth of approximately 40 to 45 feet, where a relatively transmissive zone was
encountered. Sampling data from the shallow aquifer and a deeper well (MW-10D,
screened from 75-80 feet BLS) revealed that the contamination is confined to this zone,
which will hereafter be referred to as the “intermediate aquifer.” Intermediate wells
MW-13D, MW-14D, and MW-15D were installed at the site on May 7 through May 10,
2018 to further define the lateral extent of groundwater impacts to the intermediate
aquifer. Selected historical site date is provided in Appendix A. The remainder of this
report documents the installation of two intermediate wells (MW-16D and MW-17D) and
the collection of groundwater samples from site monitoring wells in September 2020.
The opinions included herein are based on our experience and the information obtained
during the study. This report is based on limited observations made on the dates noted
using the procedures described herein. If additional information becomes available, we
request the opportunity to review the information, reassess the potential environmental
concerns and modify our conclusions and recommendations, if appropriate.

2.2 UST System Owner/Operator
According to the Wake County, North Carolina GIS mapping service, the current property
owner of the subject site is listed as WilcoHess, LLC. On October 1, 2014, Speedway,
LLC purchased the site from WilcoHess.
2.3 Information on Source of Release
On November 1, 2015, a customer at the station observed fuel spilling out the top of a
vent pipe at the site. It was determined that the regular unleaded #2 UST had been filled
to more than 90% capacity of the tank. When the pump was activated, the pressure in
the tank forced fuel up through the equipment into the TLS vault and out the top of the
vent line for the tank. It is unknown how much fuel was released.
2.4 Regional Geology and Hydrogeology
According to the map titled Geologic Map of North Carolina (1985), the subject site
is located on the boundary of the Foliated to Massive Granitic Rock physiographic
province and the Terrace Deposits and Upland Sediment physiographic province. The
site appears to be located in a megacrystic to equigranular formation described as
“Butterwood Creek intrusive and Rocky Mount intrusive suite;” and “gravel, clayey sand,
and sand, minor iron-oxide cemented sandstone.”

Groundwater in the North Carolina Piedmont region is typically found within the pore
spaces of the saprolite and alluvium deposits and within the fractures of the underlying
bedrock. In general, larger quantities of groundwater are available in valleys and
low-lying areas where saprolite thickness is usually greater.

information. Selected historical site assessment data is provided in Appendix A.
3.0 POTENTIAL RECEPTORS
Receptor information for the site was documented in Mid-Atlantic’s June 21, 2016 Phase
II LSA Report. Please refer to this report for additional information. Selected LSA data is
provided in Appendix A. For convenience, we have provided a brief summary below.
Water-Supply Wells
At the time of the LSA, the following water-supply wells were identified within a specified
distance of the source area of the gasoline release:
Based on the receptor survey conducted by Mid-Atlantic personnel on December 30,
2015, fifteen (15) water-supply wells were identified within a 1,500-foot radius of the
release area. Eleven (11) water supply wells are located within 1,000 feet of the source
of release. Of the 11 water supply wells, seven are located in a potentially downgradient
direction (to the southeast-south-southwest of the release). A water supply well was
formerly located on the subject site but is no longer in use and has been abandoned.
Public Water Supplies
According to Mr. Mark Brown, the City Engineer of the City of Raleigh Public Utilities,
a water line runs on the north side of Highway 70 to the east and west of Speedway
6959. Mr. Brown stated that this water line is used for emergency purposes only and
is unavailable to the residents and businesses of the area. A public water supply is not
available within 1,500 feet of the source area of the release.
Surface Water
According to the USGS topographic quadrangle map of Clayton, North Carolina
(Drawing 1.1), the nearest surface water bodies are unnamed streams located
approximately 1,000 feet to the northeast and southwest of the source area of the
release.
The stream located upgradient to the northeast of the subject site is identified as
Little Creek on the NCDEQ Surface Water Classifications website,
https://ncdenr.maps.arcgis.com/apps/ebappviewer/
index.html?id=6e125ad7628f494694e259c80dd64265. According to the website, Little
Creek is as a Class C Water. A Class C Water is defined as freshwaters that must
be protected for secondary recreation, fishing, aquatic life including propagation and
survival, and wildlife.

According to ArcGIS’s NC Wellhead Protection Areas website (https://www.arcgis.com/
home/ebmap/viewer.html?webmap=7492e0fe11874ccca699679d03bc0751), the
subject site is not located within an approved wellhead protection area.
Deep Aquifers in the Coastal Plain Physiographic Region
The subject site is not located in the Coastal Plain physiographic region.
Subsurface Structures
During the reconnaissance survey, subsurface utilities were investigated in the area
surrounding the site. Other than the utility lines for the USTs, no utilities were identified in
the vicinity of the release on the property. No basements were identified in the receptor
survey.
4.0 FIELD ACTIVITIES
4.1 Monitoring Well Installation
Two additional intermediate monitoring wells were installed during the reporting
period. The purpose of these wells was to try to delineate the horizontal extent of the
impact to the highly-transmissive zone that exists between 40 and 50 feet below land
surface (BLS) and to provide further information regarding the source of the release
(whether it may be migrating on-site from the Las Carolinas Grocery site). Both wells
were placed in the North Carolina Department of Transportation's (NCDOT) right of
way (ROW) of Highway 70. The general locations were agreed upon during an on-site
meeting with NCDEQ personnel on August 20, 2019. Prior to installing the wells, it was
necessary to obtain an Encroachment Agreement from NCDOT and a Monitoring Well
Construction Permit from NCDEQ. These are provided in Appendix B.
On August 31, 2020 through September 2, 2020, Geologic Exploration (Geologic), under
Mid-Atlantic's supervision, constructed two Type II groundwater monitoring
wells (MW-16D and MW-17D). The wells were constructed using 2-inch diameter,
Schedule 40 PVC casing with ten feet of 0.010-inch mechanically slotted screen. The
screens were placed from 37 to 47 feet BLS and 35 to 45 feet BLS for wells MW-16D and
MW-17D, respectively. This was done in an attempt to screen across the same highly
transmissive zone found in monitoring well MW-2D, which is located on the Speedway
property. Upon completion, the wells were equipped with locking caps and fitted with a
flush-mounted HS-20 rated manhole covers. The monitoring well construction records
(along with soil boring logs) are provided in Appendix C, with the well locations shown
on Drawing 1.2.

4.2 Liquid Level Measurements
Mid-Atlantic personnel collected liquid level measurements from site monitoring wells
on September 2 and 3, 2020 using a water level indicator. Monitoring well construction
details are provided in Table 4.1. Liquid level measurements were collected using the
procedures described in Appendix D.
4.3 Monitoring Well Sample Collection
Mid-Atlantic personnel collected groundwater samples from site monitoring wells on
September 2 and September 3, 2020. Groundwater samples were collected using the
procedures outlined in Appendix D. Groundwater samples were sent to Pace Analytical
(N.C. Certification #375) in Mount Juliet, Tennessee for analysis. Samples were analyzed
using the methods described on the chain of custody and provided in Appendix E.
5.0 DISCUSSION OF SAMPLING RESULTS
5.1 Summary of Analytical Results
A laboratory analytical report and chain-of-custody record for groundwater samples
collected on September 2 and 3, 2020 are provided in Appendix E and summarized
in Table 5.1, along with historical sampling results. As summarized, dissolved phase
petroleum compounds were detected in groundwater samples collected from multiple
wells at concentrations exceeding their respective NCGQS but below GCLs.
Contaminant concentrations decreased in the groundwater collected from well MW-1 (the
spill source area well) and is now below the NCGQS for all measured analytes. Samples
collected from new well MW-16D indicated benzene, isopropylbenzene, naphthalene,
MTBE, and C5-C8 Aliphatics at concentrations exceeding the NCGQS, while the sample
from new well MW-17D did not exhibit target compounds in concentrations exceeding
the NCGQS. Liquid level measurements (Table 5.2) indicate water table elevations were
relatively consistent with the most recent (March 2019) sampling event.
5.2 Description of Current Plume Size and Location
Isoconcentration maps for MTBE in shallow and intermediate groundwater are provided
as Drawings 5.1 and 5.2, respectively. Isoconcentration maps for benzene in the
shallow and intermediate aquifer are provided as Drawings 5.3 and 5.4, respectively.
Groundwater samples collected from shallow wells MW-2 and MW-6 and intermediate
wells MW-2D, MW-13D, and MW-16D exhibited benzene concentrations in excess of
the NCGQS. Groundwater samples collected from shallow well MW-6 and intermediate
wells MW-2D, MW-13D, and MW-16D exhibited MTBE concentrations in excess of
the NCGQS. Based on the data collected to date, the shallow aquifer contaminant
plume appear to be defined to the NCGQS by the monitoring well network. The
Speedway 6959
Clayton, North Carolina
October 30, 2020
Page 7
intermediate aquifer plume does not appear to be defined to the NCGQS by the existing
monitoring well network and the source of the contaminants remains in question. See
Section 4.4 for further discussion. It should be noted that the western extent of the
intermediate aquifer contaminant plume around well MW-16D is not defined. It is
unknown whether this plume, if originating from LCG, may be migrating beneath the
screened intervals of existing shallow monitoring wells placed on the property located at
the southwest corner of the intersection of Highway 70 and Guy Rd. The width of the
transmissive zone is not known at this time.
5.3 Additional Monitoring Information
Proximity of Plume to Nearest Receptor
Water-supply wells are located in the area. The closest potable well is located
approximately 375 feet southwest of the source area of the release. A receptor survey
map is provided in Appendix A.
Groundwater Flow Direction
An Estimated Shallow Water Table Contour Map (September 2-3, 2020) and Estimated
Intermediate Aquifer Potentiometric Contour Map (September 2-3, 2020) are provided
as Drawings 5.5 and 5.6, respectively. Liquid level measurements and groundwater
elevations are provided in Table 5.2. As shown on Drawing 5.5, groundwater in the
shallow aquifer appears to mound around MW-1 and flow radially across the site. This
may be due to an anomalously high water table in the area of monitoring well MW-1.
As shown on Drawing 5.6, groundwater in the intermediate aquifer appears to flow to the
southeast. The horizontal gradient in the shallow aquifer measured from MW-1 to MW-8
was approximately 0.030 ft/ft (Appendix B). For the intermediate aquifer, the horizontal
gradient was measured from MW-13D to MW-15D at approximately 0.011 ft/ft (Appendix
B). As summarized in Table 5.3, the vertical gradient measured from wells MW-2 and
MW-2D, wells MW-2 and MW-10D, and wells MW-11 and MW-14D was +0.017 ft/
ft, +0.007 ft/ft, and -0.034 ft/ft, respectively. Therefore, flow appears to be vertically
downward within the aquifer with the exception of the measurements for the MW-11 and
MW-14D well pair. Historical measurements have typically indicated a downward flow at
the site, although the highly transmissive zone present at approximately 45 feet BLS may
have an effect on these determinations.
5.4 Source Characterization
Intermediate monitoring well MW-2D was installed approximately 80 feet southeast of the
source area monitoring well MW-1. Concentrations of contaminants found in well MW-2D
are significantly higher than the concentrations detected in well MW-1. Vertical gradient
calculations at the site suggest that a downward gradient exists within the deep aquifer
so it is possible that contaminants are migrating vertically downward from the source
Speedway 6959

area and contributing to the higher concentrations observed in monitoring well MW-2D.
However, MTBE has not historically been detected in the shallow aquifer near the source
area of the release, whereas the concentrations in well MW-2D have ranged from 6,950
ug/L to 9,640 ug/L over the course of the project. Based on this disparity, it does not
seem likely that the high MTBE concentrations noted in well MW-2D originated from the
on-site spill in 2015.
When considering the data provided by new well MW-16D, it seems more likely that
the high MTBE concentrations present in the intermediate aquifer beneath the site
originated from the Las Carolinas Grocery (LCG) site. Additional data will be required
to more conclusively determine if there is a connection between contaminants found in
groundwater at the LCG site, the contaminant concentrations found in well MW-16D,
and the contaminant concentrations found in well MW-13D and MW-2D. It should be
noted that the highly transmissive zone was encountered in the drilling of well MW-16D
at a depth of approximately 40 to 45 feet BLS. Despite a relatively shallow water
table, no evidence of petroleum impact was encountered in the drilling of the well
until approximately 40 feet, where the top of the transmissive zone was encountered.
Additionally, Mid-Atlantic's technician noted during well development and sampling that
the well had a "very high yield" and a petroleum odor. It is possible that the LCG release
is migrating beneath Highway 70 through the transmissive zone, remaining to the west
of well MW-12D, and then entering the Speedway site. Installation of two additional wells
on either side of Guy Road and to the west of well MW-5 would help determine more
conclusively whether the intermediate aquifer contaminants (MTBE in particular) found
on the Speedway site are originating from the LCG site. The Receptor Survey Map in
Appendix A provides an aerial view of the entire area, including the LCG site.
6.0 FUTURE SITE REMEDIATION
According to the NCDEQ, the incident is currently ranked “high risk.” Because potable
water supply wells are located within 1,000 feet of the source area of the release,
the current cleanup goals for the groundwater at the site are considered to be the
NCGQS. If the LCG release can be eliminated with certainty as a contributing source of
contamination on the Speedway property, Mid-Atlantic recommends developing a CAP
for the site. If the LCG release appears to be migrating onto the Speedway site, then a
cooperative strategy will need to be developed between Responsible Parties to address
the cleanup of the releases.
7.0 CONCLUSIONS AND RECOMMENDATIONS
The following activities were conducted at the site:
• Installation of two intermediate Type II monitoring wells between the subject site
and the LCG site (MW-16D and MW-17D); and

• Groundwater samples were collected from 16 onsite site monitoring wells and two
off-site monitoring wells on September 2-3, 2020 for laboratory analysis.
Based on the results of these activities, Mid-Atlantic concludes the following:
• Dissolved phase petroleum compounds are present in shallow and intermediate
groundwater at the site above the NCGQS. The shallow aquifer contaminant
plume appears to be defined to the NCGQS by the current monitoring well
network. However, the intermediate aquifer plume is not defined. Contaminant
concentrations are significantly higher in the intermediate aquifer than in the
shallow aquifer;
• Dissolved phase petroleum compounds were identified in well MW-16D in
concentrations above the NCGQS, providing evidence that the contaminant
plume may be migrating on-site from the LCG release;
• Contaminant concentrations appear to have generally decreased in
shallow groundwater samples collected in September 2020, while intermediate
wells historically showing contamination indicated an increase in concentrations;
and
• The source of the contaminants present in samples collected from well MW-2D
and MW-13D has not been definitively identified. Based on the data, it appears
most likely that the contaminants are migrating on-site from the LCG release
across Highway 70. In this scenario, the contaminants are being transported
through a relatively transmissive intermediate aquifer present at a depth of
approximately 45 feet BLS.
Based on these conclusions, Mid-Atlantic recommends the following:
• Installation of one to two additional Type II, intermediate depth monitoring wells
to the west of monitoring well MW-5 to further determine if the contaminant plume
in the intermediate aquifer on the site is connected with the LCG release;
• Continued periodic sampling (at least semi-annual) of the monitoring wells on site
to evaluate contaminant plume movement;
• Once the source and extent of the intermediate aquifer contamination is better
understood, development of a CAP for the site; and
• Submittal of this report to the NCDEQ UST Section.

If the answer to question #3 is “NO”, skip to the certification under #8 below.
If the answer to question #3 is “YES”, please generally describe in this cell the possible
reason(s) and outline proposed remedies. (This should be described in more detail in the
report text above.)
4 Does any known or suspected source zone soil contamination or free
product remain outside of the assessed area that could be inhibiting
natural attenuation?

5 Has there been an unexpected increase in contaminant mass sufficient
to suggest a potential new release from a separate onsite or offsite
source?

If the answer to either question #4 or #5 is “YES”, generally describe in this cell any actions
recommended to further assess or clean up this known or suspected source.
As addressed in the report, we recommend installation of one to two additional intermediate

Workforce Safety Plan: COVID-19 NCDOT Encroachment ID#: _________________________
Updated: 4/11/2020 Page 1
WORKFORCE SAFETY PLAN
FOR ENCROACHMENT ACTIVITIES: COVID‐19
EFFORTS THE N.C. TRANSPORTATION INDUSTRY IS TAKING TO STOP THE SPREAD OF COVID‐19
The North Carolina Department of Transportation (NCDOT) and their partners expect all parties involved in
the delivery of transportation projects to abide by the guidelines issued from the Centers for Disease
Control and Prevention (CDC) and the North Carolina Department of Health and Human Services (NCDHHS).
Response to COVID-19 is rapidly evolving; new information and guidelines may be issued from the CDC,
NCDHHS, or other state or federal agencies. NCDOT and their partners should review the current CDC and
NCDHHS guidance, including the resources listed at the end of this document, for up-to-date information
on how to respond to COVID-19. Additional guidelines may be issued by state or federal agencies that
should be followed in addition to the guidance included in this document.
Though certain Americans with Disabilities Act (ADA) requirements have been relaxed in response to the
pandemic, employers must still maintain all information about employee illness as a confidential medical
record in compliance with the ADA. If an employee is suspected of having or tests positive for COVID-19, it
is essential that management keep the identity of the employee and details related to the employee’s
health confidential.
Below are precautions required by NCDOT and from encroaching parties and their contractors performing
construction within NCDOT Rights of Way. The term employee refers to any person on a job site within
NCDOT right of way for the purpose of constructing or inspecting the work related to construction of a
facility under an approved encroachment agreement and where that employee may or may not be under
employment by or under contract to NCDOT.
EMPLOYEE WELLNESS
• If an employee has not yet reported to work and develops any COVID-19 symptoms (i.e. fever,
coughing, or shortness of breath) — STAY HOME and immediately:
o Call a health care provider
o Self-Isolate
o Communicate with your supervisor
o Remain calm and follow all instructions from your health care provider
• Employees who appear to have acute respiratory illness symptoms (i.e. cough, shortness of breath)
upon arrival to work, or become sick during the day, should be separated from others and sent
home immediately. The potentially affected employees should immediately follow the steps
outlined above, which includes immediately contacting a health care provider.
• Should an employee show symptoms of acute respiratory illness or be diagnosed with COVID-19, all
other employees who have worked in close proximity to the affected employee during the last 14
Workforce Safety Plan: COVID-19 NCDOT Encroachment ID#: _________________________
Updated: 4/11/2020 Page 2
days and all encroachment points of contact indicated at the end of this plan should be notified of
potential exposure to the disease without identifying the affected employee.
• Consideration should be given to employees at “High Risk” of severe illness from COVID-19, who,
per NCDHHS, include employees:
o Over 65 years of age, OR
o With underlying health conditions including heart disease, lung disease, or diabetes, OR
o With weakened immune system
• “High Risk” Employees should be given the opportunity to discuss alternate work
arrangements/duties with their employer or take leave according to their company policies.
• For guidance on confirmed positive tests for COVID-19, refer to the most recent version of the
“COVID-19 Guidance for Employees on Encroachment Job Sites within NCDOT Right of Way”
located on last page of this plan.
PERSONAL HYGIENE
• Clean hands often by washing with soap and water for 20 seconds. If soap and water are not
available and hands are not visibly dirty, an alcohol-based hand sanitizer that contains 60%-95%
alcohol may be used.
• Avoid touching your eyes, nose, mouth, or other parts of your face.
• Do not breathe, cough, or sneeze on another person or into the open air. Employees should cover
their noses and mouth with a tissue when coughing or sneezing (or an elbow or shoulder if no
tissue is available).
• A facemask for covering nose and mouth is encouraged on the job site.
• Appropriate gloves are encouraged while performing functions of the job.
CLEANING/DISINFECTING
• Wash stations and/or hand sanitizer are encouraged on each project site.
• Appropriate cleaning staff should clean frequently touched surfaces and objects with disinfectants
at a minimum of once per day.
o Office/buildings: door knobs, light switches, phones, computers/keyboards, copy machines,
elevator buttons, toilets, faucets, sinks, countertops, paper towel dispensers, desktops,
handrails, folders, vending machines, counters, tables, cabinets/knobs, etc.
o Shop Yard/Jobsite: vehicle/equipment door handles, keys, gear shifts, steering
wheel/operator controls and levers, fuel pump dispensers, touch points on machinery, etc.
o Electronic equipment: cell phones, computers, keyboards, etc.
• Appropriate cleaning staff should sanitize/disinfect facilities and work areas after persons
suspected/confirmed to have COVID-19 have been in the facility or work area.
Workforce Safety Plan: COVID-19 NCDOT Encroachment ID#: _________________________
Updated: 4/11/2020 Page 3
o It is recommended to close off access to areas used by the ill persons and wait as long as
practical, 24 hours if possible, before beginning cleaning and disinfection to minimize
potential for exposure to respiratory droplets. Open outside doors and windows to increase
air circulation in the area if possible.
o Appropriate cleaning staff should clean and disinfect all areas used by the ill persons,
focusing especially on frequently touched surfaces.
GENERAL
• Increase communication measures between all parties regarding schedule, daily activities, etc. to
reduce/minimize worker exposure in accordance with but not limited to the requirements below.
• Minimize on-site personnel such as subcontractors, work crews, QC personnel, and inspection staff
to those required for that day’s activities. If work is postponed or cancelled, immediately notify
appropriate parties.
• Practice “Social Distancing” whenever feasible. Social Distancing is designed to limit the spread of a
disease by reducing the opportunities for close contact between people. All personnel have the
responsibility to remind each other to stay 6 feet or more apart. Examples of Social Distancing
include:
o Reducing face-to-face exposure by using conference calls and video conferencing
 If an in-person meeting is absolutely required and cannot be rescheduled or
attended remotely, the meeting is limited to a maximum of 10 people while
maintaining Social Distancing of 6 feet or more.
o Avoiding unnecessary travel
• Do not congregate at lunch or breaks. Bringing your lunch is encouraged.
• No communal coolers or drink stations are allowed. Supervisors should confirm with employees
prior to beginning work for appropriate hydration and nutrition availability to employees for the
duration of the employee’s shift and without direct contact with others on the job site.
• First line of communication should be by phone, rather than in-person.
• Do not shake hands.
• Do not share iPads, tablets, pens, or clipboards for signing or any other purpose. Take pictures as
proof of attendance at meetings.
• Sharing of Personal Protective Equipment (PPE) is strictly prohibited.
• Vehicles, equipment, and tools
o Limit the number of people riding in a vehicle together.
o Wipe down and disinfect vehicles after each trip.
o As much as possible, do not share tools or equipment. If a tool or piece of equipment must
be shared, the parts of it that are touched should be sanitized between uses.

APPENDIX D MID-ATLANTIC FIELD PROCEDURES
Monitoring Well Sampling Procedures

I. Sample Collection

A. Monitoring Wells

Prior to sample collection, each well is purged of three to five standing well volumes or to
dryness to remove stagnant water from the well and well bore in an effort to collect
samples that are representative of the water quality in the formation surrounding each
well. Purging is performed either with a new, polyethylene bailer dedicated to each well, or
with a decontaminated pump. Samples are retrieved from the monitoring well using the
dedicated bailer. New nylon string is used on each dedicated bailer, and new nitrile
sampling gloves are donned prior to purging and sampling of each well.

B. Geoprobe “Screen Point Sampler”

The screen point sampler is a “grab” sampling device that is driven into the saturated zone
and a surrounding metal sheath is retracted, exposing a screen. Groundwater entering the
screen is then drawn to land surface through disposable tubing that is placed through the
hollow push rods. The sample is collected from the tubing into the appropriate sampling
glassware.

C. Water-Supply Wells

Water samples are typically collected from the available spigot that is nearest to the well.
The water is allowed to run at a high flow from the spigot for approximately 10 to 15
minutes to allow the water in the delivery lines to be purged. The sample flow is then
reduced and the samples are collected directly into pre-labeled containers as described
below. New nitrile sampling gloves are donned prior to sampling of each well.

D. Treatment System Influent/Effluent

Samples are typically collected from the influent or effluent of pump-and-treat groundwater
remediation systems using designated sampling ports in the influent and effluent water
transport lines. The water is typically allowed to run for several seconds to clear potential
debris in the sampling port. The sample is then collected directly into sampling containers
as described below. New nitrile sampling gloves are donned prior to sample collection.

II. Preparation for Laboratory Analysis

Groundwater samples are decanted directly into laboratory-prepared, pre-labeled, sampling
containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control.
Laboratory analyses performed on the samples are specified on the chain-of-custody.

Groundwater Flow Direction Determination Procedure

I. Well Casing Rim Elevation Determination

After well completion, a measuring point is marked on the rim of each well casing by field
personnel. A survey level and stadia rod is used to determine the vertical elevation of the
measuring point relative to a designated site benchmark. The elevations are determined to the
nearest 0.01 foot.

II. Depth-to-Groundwater Measurements

Prior to collecting depth-to-water measurements, the field technician opens the locking well
plugs and allows the water table to “stabilize” within the well. The technician then uses an
electronic water level indicator (or oil/water interface probe, if free product is present) to
measure the depth-to-water from the measuring point on the casing rim to the nearest 0.01
foot. The measured depths-to-water are then subtracted from the casing elevations to
determine water level elevations relative to the benchmark.

III. Horizontal Flow Direction Determination

Horizontal groundwater flow direction in the surficial aquifer is determined by development of a
water table contour map based upon water table elevation data obtained from site monitoring
wells. The water levels measured in deep, Type III monitoring wells are not used in
constructing the water table map. Mid-Atlantic uses Golden Software’s “Surfer” version 7.0 to
generate the contours using the Kriging method. Alternatively, the water-table contour map
may be hand drawn by Mid-Atlantic staff and then digitized by AutoCAD software.
Groundwater flow direction is determined by interpreting the contours. Groundwater will flow in
the direction from higher elevation to lower elevation (perpendicular to the generated
contours).

IV. Vertical Flow Direction Determination

Groundwater exhibits both horizontal and vertical components of flow through an aquifer. The
hydraulic gradient is the difference in hydraulic head divided by the distance along the flow
path. The vertical gradient may be either up or down within the aquifer.

The vertical gradient is calculated using measurements obtained from a “paired” shallow
monitoring well and a deep, Type III monitoring well. The gradient is calculated by first
determining the difference in the static water level elevations at the well pair. Second, the
relative elevation of the middle of the screened interval is determined for each well pair.
Finally, the difference in the static water level elevations at each well pair is divided by the
difference in the mid-screen elevations for the well pair. This value is arbitrarily assigned a
positive value if the groundwater is moving vertically downward (recharge area) and a negative
value if the groundwater is moving vertically upward (discharge area). Groundwater will flow in
the direction from higher elevation to lower elevation.
Hydraulic Gradient Determination Procedure

The hydraulic gradient, which is a measure of the “steepness” of the water table, is
determined by dividing the change in the elevation (in feet) of the water table over the
change in horizontal distance (in feet) between two measuring points. Typically, the
gradient is determined after the Water Table Elevation Contour Map is prepared. Two
wells are typically selected that, when a line is drawn between the wells, the orientation of
this line approximates the direction of groundwater flow. The greater the horizontal
distance between the lines, the more representative the hydraulic gradient value will be for
the site. If two wells are not arranged in line with groundwater flow, the hydraulic gradient
can be estimated by performing the same calculation using the contours generated for the
groundwater flow direction map. The units for the hydraulic gradient are feet/feet.

The hydraulic gradient for the subject site (as measured from monitoring well MW-4 to
MW-18) on May 20, 2019 was determined as follows:

Gradient = dh/dl = (74.57 – 62.46) / 300 = 0.040 ft/ft

where:

dh = change in head (more specifically, water table elevation) in feet
dl = horizontal distance (in feet) between monitoring wells or other head measurement
points.

The hydraulic gradient for the subject site (as measured from monitoring well MW-4 to MW-
18) on March 6, 2020 was determined as follows:

Gradient = dh/dl = (74.96 – 63.55) / 300 = 0.038 ft/ft

where:

dh = change in head (more specifically, water table elevation) in feet
dl = horizontal distance (in feet) between monitoring wells or other head measurement
points.

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
C4 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Data is likely to show a low bias concerning the result.
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.
