EXECUTIVE SUMMARY
Speedway #7921 is located at 2702 NC Highway 105 in Boone, Watauga County, North Carolina. The site
is currently operated by Speedway, LLC as a petroleum retail facility. Four 5,000-gallon gasoline USTs, one
5,000-gallon diesel UST, one 5,000-gallon kerosene UST and one 5,000-gallon gasoline UST (previously
closed in place on May 24, 2016) were excavated and removed from the site on January 31, 2018. Soil
and ground water contamination was confirmed at the site. One 20,000-gallon double-walled fiberglass
gasoline UST and two 12,000-gallon double-walled fiberglass USTs (gasoline and compartmentalized
diesel/kerosene) are currently in operation at the site. The overall topography at the site is inclined with
a down gradient from northwest to southeast. The site contains one building and is primarily capped with
concrete and asphalt. The site and surrounding area are a mixture of general business, residential, and
agricultural properties.

On October 24, 2016, GRI personnel conducted a receptor survey at the site. There are two non-potable
water wells located within 250 feet of the source area and five potable wells are located between 250
feet and 1,000 feet of the site. Municipal water is available to the site and surrounding properties. Hodges
Creek, a small ditch parallel to Homespun Hill Road, and a culvert are located within a 500-foot radius of
the source area. Hodges Creek is classified as Class C/Trout Waters and is located to the west and south
of the site, flowing eastward approximately parallel with NC Highway 105. A tributary of the creek runs
through a culverted section along the eastern property boundary of the site. At the closest point to the
site, Hodges Creek is culverted and located within 50 feet to the southwest.

On August 31, 2020, three replacement Type II monitoring wells, MW-1R, MW-2R, and MW-5R, were
installed in the vicinity of MW-1, MW-2, and MW-5, respectively. The previously installed monitoring wells
had been paved over. Subsequently, five Type II monitoring wells (MW-1R, MW-2R, MW-3, MW-4, and
MW-5R) were gauged, purged and/or sampled. The MACs and ten times the 2B standards were below
the concentration of several contaminants in MW-1R, MW-2R, and MW-3. All reported contaminant
concentrations were below the GCLs. The total contaminant mass for the August 2020 event was
estimated to be 725.28 grams.

On July 21, 2021, four Type II monitoring wells (MW-2R, MW-3, MW-4, and MW-5R) and three water
supply wells (WSW-2, WSW-4, and WSW-8) were gauged, purged and/or sampled. The MACs were below
the concentrations of benzene, xylenes, n-propylbenzene, tert-butyl alcohol, and 1,2,4-trimethylbenzene,
reported in the ground water samples collected from MW-2R, and MW-3. All reported contaminant
concentrations were below the GCLs and ten times the 2B standards. No detectable concentrations of
target analytes were reported for any of the water well samples. The total contaminant mass for the site
based on the July 2021 event was estimated to be 363.33 grams, an approximate 50% reduction since the
baseline sampling event.

Based on this information, the risk classification for the site should remain high risk and a CSA should be
conducted. MMPE events should be conducted at the site until contaminant concentrations are below
the MACs. Semi-annual ground water monitoring should continue at the site. GRI will verify the status of

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of the July 2021 ground water sampling event at the Speedway #7921 site; located
at 2702 NC Highway 105 in Boone, Watauga County, North Carolina (Figure 1). These activities were
conducted in accordance with GRI Proposal No. 21-418, which was submitted to the NCDEQ on July 8,
2021, and was approved as Task Authorization No. 44711-8 on July 14, 2021. State correspondence has
been included as Appendix A.

The site is currently owned by Sodalis Investments II, LLC and is operated by Speedway, LLC as a petroleum
retail facility and convenience store. Four 5,000-gallon gasoline USTs, one 5,000-gallon diesel UST, one
5,000-gallon kerosene UST and one 5,000-gallon gasoline UST (previously closed in place on May 24, 2016)
and the associated product piping and dispensers were excavated and removed from the site on January
31, 2018. Soil and ground water contamination was confirmed at the site and reported to the NCDEQ on
June 8, 2016. One 20,000-gallon double-walled fiberglass gasoline UST and two 12,000-gallon double-
walled fiberglass USTs (gasoline and compartmentalized diesel/kerosene) are currently in operation at the
site. UST owner/operator information and UST system information are included as Tables 1 and 2,
respectively. The Registered Tank Report is shown below:

The site and surrounding area are a mixture of general business, residential, and agricultural properties.
A copy of the Land Use table has been included as Appendix B. An excerpt from the Town of Boone

Unified Development Ordinance that describes the general allowances of zoning code B3 has been
included as Appendix C. The site contains one building and is primarily capped with concrete and asphalt.
The overall topography at the site is inclined with a down gradient from northwest to southeast. Hodges
Creek, a small ditch approximately parallel to Homespun Hill Road, and a culvert are located within a 500-
foot radius of the source area. Five Type II monitoring wells (MW-1 through MW-5) were installed at the
site during previous ground water assessment activities. A Site Map showing the locations of the
monitoring wells and the structures on-site has been included as Figure 2.

On October 24, 2016, GRI personnel conducted a receptor survey at the site. Ten water supply wells are
located within 1,500 feet of the site. One non-potable well (WSW-2) is located within 250 feet of the
source area and five potable wells (WSW-4, WSW-6, WSW-7, WSW-8 and WSW-10) are located between
250 feet and 1,000 feet of the site. Please note that WSW-1 has reportedly been abandoned. The well
abandonment record is currently unavailable; however, GRI will verify the well status during the next site
visit and include photographs of the well in the next Ground Water Monitoring Report. To date, a
concentration of ethanol below the MAC has been reported in WSW-8. This contamination was reported
to Ms. Linda Estkowski of the NCDEQ. Municipal water is available to the site and surrounding properties;
however, municipal water is not available to the properties containing potable water supply wells WSW-
3 through WSW-10. Hodges Creek is classified as Class C/Trout Waters and is located west and south of
the site, flowing approximately parallel with NC Highway 105. A tributary of the creek runs through a
culverted section along the eastern property boundary of the site. At the closest point to the site, Hodges
Creek is culverted and located within 50 feet to the southwest. Water supply well information is provided
in Table 3. Adjacent property owner information is presented in Table 4. A Site Vicinity Map showing the
adjacent properties and a Zoning Map showing the zoning information have been included as Figures 3a
and 3b, respectively.

On February 17, 2016, water was observed in the STP sump of the 5,000-gallon premium gasoline UST #4.
After the tank and STP sump were inspected, it was determined repairs could not be made and a decision
was made to permanently close the tank. The premium gasoline UST #4 was closed-in-place by filling with
Perma-Fill on May 24, 2016. Soil and ground water contamination was confirmed at the site following
closure-in-place assessment activities and reported to the NCDEQ on June 8, 2016, and the site was issued
Incident No. 44711. On January 12, 2018, the regular gasoline UST #2 was reported to be taking on water.
The tank subsequently failed a tank tightness test. The diesel UST #6 was also reported to be failing. Given
the ages of the tanks and a total of three (3) USTs at the site that had failed since 2016, Speedway, LLC
decided to remove the existing UST system and concurrently replace it with a new system. This release
was reported to NCDEQ on January 15, 2018. This release was included in Incident No. 44711.

One previous incident was reported at the site. Incident Number 5984 was reported in September 1990
based on the reported observation of petroleum contaminated soil by the NCDOT. This incident was
closed in August 1992 based on NCDEQ internal memo stating no evidence of a current or past release
was observed at the site. One incident (Incident No. 44581) has been reported on an adjacent property.

Copies of the NCDEQ Incident Reports have been included as Appendix D. A map showing the locations
of additional incidents in the vicinity of the site is shown below:

To date, remedial activities have exclusively been conducted during the 2018 UST closure. Approximately
1,711.05 tons of contaminated soil and a total of 324,592 gallons of free product/contaminated ground
water were removed from the site during the closure activities.

On August 31, 2020, five Type II monitoring wells (MW-1R, MW-2R, MW-3, MW-4, and MW-5R) were
gauged, purged and/or sampled. The MACs were below the concentrations of benzene, toluene, xylenes,
naphthalene, isopropylbenzene, n-propylbenzene, 1,2,4-trimethylbenzene, 1-methylnaphthalene, 2-
methylnaphthalene, lead, C9-C18 aliphatics, and C11-C22 aromatics reported in the ground water samples
collected from MW-1R, MW-2R, and MW-3. Ten times the 2B standards were below the concentrations
of toluene, naphthalene, and/or lead reported in monitoring wells MW-1R, MW-2R, and MW-3. All
reported contaminant concentrations were below the GCLs.

Based on this information, the site was classified as high risk and a CSA was recommended in previous
assessment reports.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
Soil assessment was not conducted during the current scope of work. Historical soil quality information
has been included as Appendix E.

On July 21, 2021, four Type II monitoring wells (MW-2R, MW-3, MW-4, and MW-5R) were gauged, purged,
and sampled in accordance with the NCDEQ guidelines. MW-1R was neither gauged, purged, nor sampled

because of an obstruction in the well. Depths to ground water in the Type II monitoring wells ranged from
4.21 feet to 5.37 feet. Ground water elevations in the Type II monitoring wells ranged from 93.84 feet to
95.57 feet. Ground water flow was generally to the south and southeast with a horizontal gradient of
approximately 0.06 feet per foot. No vertical gradient could be calculated since no telescoping well has
been installed at the site. Well construction and gauging information is presented in Table 5. Additional
field parameters were collected during the July 2021 ground water sampling event and are presented in
Table 6. A Water Table Surface Map based on the Type II monitoring wells is included as Figure 4. A

Ground water samples were collected from the on-site monitoring wells, as well as water wells WSW-2,
WSW-4 and WSW-8. The owner of WSW-10 denied access for sampling their well. The collected samples
were submitted for laboratory analyses by EPA Method 6200B. The MACs were below the concentrations
of benzene, xylenes, n-propylbenzene, tert-butyl alcohol, and/or 1,2,4-trimethylbenzene reported in the
ground water samples collected from MW-2R and MW-3. All reported contaminant concentrations were
below the GCLs and ten times the 2B standards. No detectable concentrations of target analytes were
reported for any of the water well samples. A summary of the analytical results for ground water samples
collected on July 21, 2021, is presented in Table 7. A Ground Water Quality Map based on the July 2021

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE, and
naphthalene concentrations from the August 2020 ground water sampling event as well as the maximum
historical water column height observed in each area. Please note, since MW-1R could not be gauged or
sampled, for calculation of contaminant mass, it was assumed that the contaminant concentrations and
depth to water were the same as during the baseline event. Based on the July 2021 sampling event, the
current total contaminant mass in Area 1 and Area 2 were 320.80 grams and 42.53 grams, respectively.
The percent reductions in contaminant mass from the baseline event for Areas 1 and 2 are 15.9% and
87.6%, respectively. The total contaminant mass for the July 2021 event was estimated to be 363.33
grams, which is a 50% reduction in mass from the baseline event in August 2020. Contaminant mass
calculations have been included as Appendix G. A map of the contaminant mass areas has been included
as Figure 7. A chart showing the change in contaminant mass over time is presented below.

No CAP has been established since the contaminant plume is not yet fully defined. Please note that
milestones were not yet established.
3.0 FREE PRODUCT REMOVAL
No free product has historically been present at the site.

4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
Due to the site being in the assessment phase, no natural attenuation monitoring plan is currently in place
at the site.
5.0 CONCLUSIONS
 On July 21, 2021, four Type II monitoring wells (MW-2R, MW-3, MW-4, and MW-5R) were gauged,
purged, and sampled in accordance with the NCDEQ guidelines. MW-1R was neither gauged,
purged, nor sampled because of an obstruction in the well. Depths to ground water in the Type II
monitoring wells ranged from 4.21 feet to 5.37 feet. Ground water elevations in the Type II
monitoring wells ranged from 93.84 feet to 95.57 feet. Ground water flow was generally to the
south and southeast with a horizontal gradient of approximately 0.06 feet per foot.
 Water supply wells WSW-2, WSW-4, and WSW-8 were also sampled. The owner of WSW-10
denied access for sampling.
 The MACs were below the concentrations of benzene, xylenes, n-propylbenzene, tert-butyl
alcohol, and 1,2,4-trimethylbenzene, reported in the ground water samples collected from MW-
2R and MW-3.
 All reported contaminant concentrations were below the GCLs and ten times the 2B standards.
No detectable concentrations of target analytes were reported for any of the water well samples.
 The total contaminant mass for the July 2021 event was estimated to be 363.33 grams, an
estimated 50% reduction from the baseline event calculated mass.
 Please note that the plume is undefined to the north, south, and east.
 Based on the compiled information, the risk classification for the site should remain high risk and
a CSA should be conducted. MMPE events should be conducted at the site until contaminant
concentrations are below the MACs. Semi-annual ground water monitoring should continue at
the site. GRI will verify the status of water supply well WSW-1 during the next ground water
sampling event. The next sampling event is tentatively scheduled for January 2022.

44711
Description of Release
An observation of petroleum contaminated soil was reported by the NCDOT. This
incident was closed in August 1992 based on NCDEQ internal memo stating no
evidence of a current or past release was observed at the site. Please note that this
release is not associated with any of the current or previous USTs.
Water was observed in the STP sump of the 5,000-gallon premium gasoline UST #4.
The premium gasoline UST #4 was considered unrepairable and was closed-in-place
by filling with Perma-Fill on May 24, 2016. Additional tank failures were reported in
January 2018 and all the USTs were removed and replaced.

February 18, 2021 CT Corporation System, Registered Agent Speedway (North Carolina) LLC 160 Mine Lake Ct Ste 200 Raleigh, NC 27615-6417 Subject: Speedway 7921, 2702 Hwy 105, Boone, Watauga County, Incident # 44711, Risk Classification: High, Ranking: 165 Dear Madam or Sir: Ground Water Monitoring Report, dated November 10, 2020, has been reviewed. Based on the review, the report has been determined to be incomplete. Please revise and submit a report that includes the following information: 1. History Section: This section needs to describe the history such that someone that is completely unfamiliar with the site will understand the site. i. Please clarify the tank removal history. It sounds like seven tanks were closed in place on May 24, 2016. Which tank(s) were closed in place? Date? Was a release discovered? What tanks were removed? Date? Which tanks had a release? ii. Indicate whether-or-not the pipes and dispensers were removed. Date? Was a release discovered? If yes, which dispensers, which lines? iii. Indicate dates of all petroleum releases, present and past, that occurred on the property and on nearby properties. Include dates, type of source, incident numbers, whether-or-not there are comingled soil and/or groundwater contaminant plumes, and any other pertinent information. iv. Describe all potential petroleum release sources, both on the property and on nearby properties. (ASTs, hydraulic lifts, service stations, spills, etc). v. Indicate previous reports submitted with dates. vi. Describe all remedial actions taken to date (removal/repair/replacement of dispensers, lines and/or tanks, all soil excavation events, all free product removal events, all water removal events, water supply well abandonments, hooking properties to public water, providing alternate drinking water, AFVR/MMPE events, remediation system operations, etc.) Include dates and amounts of soil, free product, and liquid removed. vii. Indicate whether any water supply wells have been impacted, with what constituent, and to what level (greater or less than 2L and greater or less than the MCL’s). What actions were taken (health risk evaluations and results, alternate water provided, well abandonment, etc.). viii. Is municipal water available to all properties within 500 feet of the source area(s)?
Is municipal water available to all properties within 1,000 feet of the source area(s)? This is important information because a water supply well, located about 550 feet from the source area had an ethanol detection of 2,030 ppb on August 31, 2020.

ix. Please indicate that one of the “non-potable” water supply wells is used to fill a hotel swimming pool. x. Indicate the zoning of the property. Indicate whether-or-not the zoning designation allows for various types of residential uses (daycares, parks, nursing homes, residences, schools, playgrounds, etc.)? 2. Current Site Assessment Information/Comparison to Historical Assessment Information:
i. Describe all soil monitoring events (dates, type of event such as tank closure or confirmation sampling after soil excavation, levels of contamination during each monitoring event). ii. Determine the estimated initial soil contaminant baseline. iii. Determine the estimated most current soil contaminant baseline. iv. Determine the estimated initial groundwater contaminant baseline.
3. Table 1: Include the tanks that were removed for incident 5984. 4. Table 2: i. Indicate that tank 4 was removed in addition to it being closed in place. Include the date of removal.
ii. Include information as outlined on Table B-1: Site History, found in the appendix of the Guidelines. (AST information, all incidents on the property (incident 5984,
2016 release, 2018 release)). 5. Table 3: i. Include other receptors (surface water bodies) as outlined in Table B-5: Public and Private Water Supply Well and Other Receptor Information, found in the
appendix of the Guidelines. ii. Put the date that the last receptor survey/updated receptor survey was done at the
top of the table. 6. Table 6:
i. Include a column, in the body of the table, for ALL detected contaminants in water supply wells, regardless of concentration. ii. Include field parameters listed under task code 4.031 in the Trust Fund’s Reasonable & Necessary Task Scope-Of-Work Document in the table.
7. Provide Table B-3: Summary of Soil Sampling Results, found in the appendix of the Guidelines. Include all samples taken for all phases (site check, closure, initial abatement, post excavation, etc.). 8. Figure 2 indicates that wsw-1 was abandoned. However, Figure 3 and Table 3 indicate that wsw-1 is operational. Was wsw-1 abandoned in accordance with 2C or is wsw-1 just not being used? Please adjust the figures and tables accordingly. Also, the text, under
section 1.0 may need to be clarified. 9. Site map: i. Include the location of all present and former UST systems (tanks, lines, dispensers), present and former ASTs, present and former hydraulic lifts, spills, and any other petroleum sources/potential sources on the property, ii. Label petroleum sources/potential sources to correlate with tables, iii. Include location(s) of nearby off-site petroleum releases and potential petroleum sources, iv. Include all soil excavation areas, v. Include all present and former monitoring and remediation wells.
10. Include the following on two groundwater cross-sections: i. Soil, saprolite, and bedrock boundaries and characteristics, ii. Groundwater table, iii. A contour line for groundwater contamination above 2L and a contour line for groundwater contamination above gross contaminant levels, iv. Soil excavation areas,
v. Monitoring, remediation, and water supply wells with screens. Project nearby wells onto the cross-section.

vi. Present and former UST systems (tanks, lines, dispensers), ASTs, and other petroleum release/potential release sources, vii. Buildings, streets, utilities, and basements, viii. Any other pertinent information. 11. Include the following on a soil map: i. All soil sample locations ever taken (environmental assessment, site check,
closure, assessment, and remediation phases), ii. Correlate sample locations with the table, iii. Area of soil excavation(s), iv. Contour lines of soil contamination above soil-to-groundwater, residential, and industrial/commercial standards where applicable. (Soil samples above the TPH action levels of 50 ppm gas and 100 ppm diesel should be considered to be above
the residential standards. Please note: Risk-based analytical numbers take priority over TPH numbers when determining the level of soil contamination.). v. Present and former UST systems (tanks, lines, dispensers), ASTs, and other petroleum release/potential release sources,
vi. Monitoring, remediation and water supply well locations, vii. Soil cross-section locations.
viii. Any other pertinent information. 12. Provide two soil cross-sections with the following information: i. Soil sample locations, ii. Label soil sample points to correlate with tables,
iii. Include a contour line for soil contamination above each of the following levels where applicable: soil-to-groundwater, residential, and industrial/commercial.
(Soil samples above the TPH action levels of 50 ppm gas and 100 ppm diesel should be considered to be above the residential standards. Please note: Risk-
based analytical numbers take priority over TPH numbers when determining the level of soil contamination.).

Hi Joanna,

Ok, I see for the baseline contaminaon figure. That looks good.

A photo would work.

Thanks and hope you have a nice weekend,

Good Morning Linda,

I am looking over your leer now and am not sure what you are wanng from Figure 6. This map
is the Contaminant Mass Area Map. It is showing the areas that were established for the baseline
event (08/31/20). These areas do not change for the contaminant mass calculaons, otherwise
they would not be an accurate representaon of the trends at the site. Are you just looking for a
current benzene Isoconcentraon Map? If that is the case, I can add that figure into the report,
but the Figure 6 needs to remain constant for all ongoing reports.

Please note that we are aempng to confirm; however, WSW-1 is reportedly abandoned (not
simply out of use). Abandoned indicates that the well has been grouted and can no longer be
used. We do not have the well abandonment record as GRI did not abandon this well, but we are
aempng to locate it. If we cannot locate the abandonment record, we can have a photo taken
of the well confirming the status during the next round of sampling. Would that suffice?

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

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.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
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
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be
considered minimum values.

Notes:
• FP: Free Product
• Baseline contaminant mass was calculated using the maximum water column observed as well as the maximum historical dissolved phase contaminant concentrations.
*: MW-1R was obstructed and could not be gauged or sampled. Contaminant concentrations and depth to water from previous event used for calculations.
• Contaminant mass cannot be calculated in wells containing FP; therefore, the total contaminant mass is based on the known concentrations in the area for each sampling event.
