2.0 SITE BACKGROUND
2.1 Site Description
The subject property consists of four contiguous parcels of land totaling 6.602 acres located on the
southeast side of Toomey Avenue and the north side of West Tremont Avenue within a mixed light-
industrial, commercial, and residential area of Charlotte, Mecklenburg County, North Carolina. The subject
property is currently developed with three buildings totaling 15,664 square feet and constructed in 1931
and 1994. The subject property is currently occupied by Charlotte Dumpster Rentals (2301 Toomey Avenue),
SPCA of Charlotte (2315 Toomey Avenue), and Ultimate CrossFit/Charlotte Jiu Jitsu Academy (704 West
Tremont Avenue) for commercial use. In general, on-site operations consist of office administration, bin
storage, health and fitness training, martial arts training, and associated property maintenance. In addition
to the current structures, the subject property is improved with a small storage shed, asphalt- and gravel-
paved parking areas, security fencing, and associated landscaping.
The immediately surrounding properties consist of Carolina Custom Tank followed by Toomey Avenue,
Service Metal, Gas-Fired Products, vacant commercial buildings, and W.A. Smith / Duct Fabrication, Inc. to
the northwest; single-family residences along Wilmore Drive to the northeast; vacant parcels to the
southeast; Brookhill Village Apartments to the south across West Tremont Avenue; and Al's Mini Mart
followed by West Tremont Avenue and Life Center Charlotte to the southwest. Refer to Figure 1 for a site
vicinity map showing site features and surrounding properties.
2.2 Site History
Partner completed a Phase I Environmental Site Assessment (Phase I) Report, dated December 11, 2020, for
the subject property on behalf of Abacus Capital. Based on review of historical sources, the subject property
was formerly undeveloped land as of 1905. In 1931, the existing converted residence and detached garage
on the southwest parcel (2315 Toomey Avenue), as well as an additional residence and a small commercial
building were constructed. By 1943, the south parcel (704 West Tremont Avenue) was developed with
several row houses adjacent to West Tremont Avenue. The additional residence and commercial building
on the southwest parcel as well as the row houses along West Tremont Avenue were later razed by 1993.
The existing warehouse was then constructed on the south parcel in 1994. Partner also notes that a trailer
and material storage yard were later identified on the northeast parcel (2207 Toomey Avenue) in 2006. The
trailer was no longer visible in the 2009 aerial photograph. Tenants on the subject property have included
various residential tenants (1931-2014); Little Ray Shoemaker (1931); Toomey Brothers Plumbing & Heating
Company (1931-1979); Jones Fencing & Grading (1995-2014); Amerit Fleet Solutions (2015-2018); Ultimate
CrossFit / Charlotte Jiu Jitsu Academy (2019-present); Charlotte Dumpster Rentals (present); and SPCA of
Charlotte (present).
The following recognized environmental concerns (RECs) were identified in the Phase I:
• The southeast adjacent property, identified as Powers Site at 536 West Tremont Avenue
(erroneously listed as 436 West Tremont Avenue in the regulatory database report), was listed in
the North Carolina Brownfields and Institutional Control databases. According to records
obtained from the North Carolina Department of Environmental Quality (NCDEQ), the site
historically operated as a quarry from before the 1920’s through the 1930’s. Following its use as

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 4
a quarry, the site was filled to grade with apparent waste casting sand, concrete, wood debris and
gravel in addition to soil materials from unknown sources. It was then occupied by a model
building manufacturer in the late 1930’s, a brick manufacturer for a short time in the early 1940’s,
a riding academy in the mid-1940’s, a junkyard from the 1960’s through 2005, and improved with
a radio tower and used for construction debris storage/dumping until some point prior to 2018.
The property was purchased in 2016 and proposed redevelopment consisted of mixed-use
commercial and (high density) residential. A Brownfields Property Application dated June 21,
2016 was submitted to the NCDEQ and an approved Notice of Brownfields Property (Notice) with
Environmental Land Use Restrictions (ELURs) was filed on October 6th, 2017 (Brownfields Project
ID: 20045-16-060). The Notice indicated the use of the property is limited to storage unit,
warehousing, retail, office, parking, high density residential, and with prior NCDEQ approval, other
commercial uses.
Based on a review of the Environmental Management Plan dated August 9, 2018 (required for
redevelopment), a Brownfields Assessment performed in May 2017 found contaminants of
concern on the central, southern and eastern portions of the site; specifically, methyl tertiary butyl
ether (MTBE) in groundwater above the 15A NCAC 2L Groundwater Quality Standards;
naphthalene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, bis(2-
ethylhexl)phthalate, dibenz(a,h)anthracene, ideno(1,2,3-cd)pyrene, arsenic, cadmium, mercury,
lead, and total petroleum hydrocarbons (TPH)–diesel range organics (DRO) in soil above the
residential screening levels; and methane content at greater than 5% Lower Explosive Limit (LEL).
A portion of the eastern side of the site is underlain by suspected coal tar residuals that are the
likely source for methane generation and migration. Proposed redevelopment of the site includes
the construction of buildings with sub-slab methane mitigation systems utilizing a membrane
barrier impervious to methane transmission and a sub-slab venting network. According to the
most recent ELUR Update, a compliance inspection was completed on the property in February
2020. At that time, it was determined that the property was in compliance and abiding by the
restrictions set forth in the ELUR.
According to the analytical results, soil and groundwater contamination appear to be confined to
the Powers Site. The methane gas assessment indicated that the highest concentrations were
located in the vicinity of the former pit on the eastern portion of the Powers Site and decrease in
the direction of the subject property. According to the analytical results, two of the methane
sampling points located closest to the subject property were identified as SB-11 and SB-15. These
sampling points contained methane at concentrations greater than the 5% LEL in March and May
2017. Based on the analytical results and close proximity to the subject property, the potential
exists for methane to be located beneath the subject property at concentrations above the 5%
LEL. As such, the adjacent Powers Site represented a REC.
• The southeast-adjacent property, identified as Adams Property at 510 West Tremont Avenue, was
listed in the North Carolina Brownfields database. According to historical sources and records
obtained from the NCDEQ, this property was also formerly occupied by the same quarry as 536
West Tremont Avenue from before the 1920’s through the 1930’s and subsequently occupied by
an auto salvage yard and a small automotive repair facility from the 1960’s through 2005. A
Limited Subsurface Investigation performed in September 2016 identified TPH-DRO, arsenic,
barium, lead, benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene in on-site soils at
concentrations that exceeded their respective Industrial/Commercial Preliminary Soil

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021

Remediation Goals (PSRGs) and/or Protection of Groundwater SRGs. Groundwater was not
encountered or sampled during this event.
In February 2017, an additional subsurface investigation was conducted at the site which included
soil, soil gas, and groundwater sampling. According to the analytical results, several metals were
identified at concentrations exceeding their respective Protection of Groundwater SRGs,
Residential PSRGs, and/or Industrial/Commercial PSRGs in the on-site soils. In addition,
extractable petroleum hydrocarbons (EPH) were detected in two soil samples at concentrations
above the Residential and Protection of Groundwater SRGs. Volatile petroleum hydrocarbons
(VPH) were also detected in one soil sample at a concentration that exceeded the Protection of
Groundwater SRG. The groundwater analytical results indicate that naphthalene, lead, and
manganese were detected at concentrations that exceed their respective NCDEQ Groundwater
Quality Standards (GWQS).
Based on the analytical results, a Brownfields Property Application was submitted to the NCDEQ
in April 2017. The NCDEQ subsequently responded with a Letter of Eligibility (LOE) on May 17,
2017 (Brownfield Project ID: 21022-17-060). The LOE outlined additional requirements in order
to receive a Notice of Brownfields Property designation with the proposed multi-family
residential, townhome-style residential, office, commercial, retail, hotel, and/or open space use.
In June 2019, the NCDEQ requested additional assessment of soil and groundwater to
characterize conditions and the risk of methane gas or vapor intrusion. As a result of a subsurface
investigation performed in July 2019, hexavalent chromium and several semi-volatile organic
compounds (SVOCS) including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,
dibenz(a,h)anthracene, and ideno(1,2,3-cd)pyrene) were detected at concentrations that
exceeded their respective Residential PSRGs; however, they did not exceed their
Industrial/Commercial PSRGs. Concentrations of arsenic also exceeded both the Residential and
Commercial PSRGs. According to the groundwater analytical results, several volatile organic
compounds (VOCs), SVOCs, and RCRA metals were identified at concentrations that exceeded
their respective 15A NCAC 2L Groundwater Quality Standards. While total chromium was
detected above the 15A NCAC 2L Groundwater Quality Standard, speciation analysis indicated
that the detected concentrations were that of trivalent chromium and were therefore likely to be
naturally-occurring. In addition, during soil gas sampling it was noted that 1,3-butadiene and
m/p-xylene were detected above the Residential Soil Gas Screening Levels (SGSLs). The 2019
assessment also noted that methane concentrations ranged from 0 to 56.8%. A Notice of
Brownfields Property has not yet been filed for the property.
According to the analytical results, soil and groundwater contamination appear to be confined to
the Adams Property site. The methane gas assessment indicated that the highest concentration
is located on the north-central portion of the property, identified as location B-7. This sampling
point is located approximately 50 feet south of the 2207 Toomey Avenue parcel boundary. Based
on the analytical results and close proximity to the subject property, the potential exists for
methane to be located beneath the subject property at concentrations above the 5% LEL. As such,
the adjacent Adams Property represented a REC.
• During the site reconnaissance, Partner observed heavy equipment/machinery and assumed
empty aboveground storage tanks (ASTs) and 55-gallon steel drums on the 2207 Toomey Avenue
parcel. Heavy vegetation prohibited a complete inspection of the ground surface in this portion
of the subject property. Therefore, it is possible that leaks or releases of hazardous substances
and/or petroleum products from the equipment/machinery and/or containment vessels have

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 6
occurred and potentially impacted near-surface soils in this area. As such, the observed
equipment/machinery, ASTs, and 55-gallon drums represented a REC.
The following controlled recognized environmental condition (CREC) was identified in the Phase I:
• The northwest adjacent property, identified as Dynatech at 2213 Toomey Avenue, was listed in
several regulatory databases including the State Hazards Waste Site (SHWS), North Carolina
Brownfields, and Institutional Control databases. According to records obtained from the NCDEQ,
Dynatech Industries, Inc. occupied the property as well as a small portion of the 2207 Toomey
Avenue parcel from at least 1985 to 1990. Primary on-site operations consisted of hard chrome
plating of camshafts for large scale industrial air compressors. Numerous hazardous wastes were
generated as part of this operation, some of which were disposed directly into a septic system
through a drain located at the front of the building. The septic system was reportedly located on
the 2301 Toomey Avenue parcel associated with the subject property.
In October 1985, it was found that a discharge from a malfunctioning septic tank used by the
facility may have contaminated the 2315 Toomey Avenue parcel. In January 1986, the main
building was disconnected from the septic system and connected to the municipal sewer. A
confirmed release of chromium to the nearby intermittent tributary was reported on January 31,
1989, as a result of improper management of hazardous materials and wastes. Resource
Conservation and Recovery Act (RCRA) closure was initiated at the site by Dynatech in July 1990;
however, inadequate finances caused them to abandon the facility prior to completion. Analytical
data indicated that high levels of hexavalent chromium were present in the soil and groundwater
near the former chrome plating area. Some contaminated soil was excavated and disposed offsite
prior to abandonment of the property.
From 1992 to 1994, the United States Environmental Protection Agency (USEPA) conducted
various activities on-site, including: properly securing and removing hazardous materials;
sampling various mediums for contamination including surface soils, subsurface soils,
wastewater, sediment, groundwater, etc.; removal of contaminated materials including soil,
groundwater, and wastewater; and backfilling the excavation areas with clean fill material.
Although historical evidence indicated a release to the groundwater, the threat posed by the
groundwater pathway was considered minimal as no groundwater users were identified within
3.0 miles of the site. Analytical results indicated that the fishery at Irwin Creek was impacted with
several metals. However, no releases from the property could be established based on
background samples suggesting that the source of contamination may have originated
elsewhere. The biggest threat posed by the soil exposure pathway was identified as the septic
tank area located on the 2301 Toomey Avenue parcel. However, the chromium concentration
did not exceed the USEPA health-based benchmark for soil chromium exposure in the soil. Based
on the above assessment, the North Carolina (NC) Superfund Section recommended no further
action and that the property be assigned a No Further Remedial Action Planned (NFRAP) status.
The USEPA confirmed the Remedial Site Assessment Decision on December 1, 1994.
In 1999, during attempts to obtain a business loan, the property owner (Mr. Robert Gilbertson of
RG Automation) was required by the bank to obtain a Brownfields agreement in order to acquire
immunity from the existing environmental concerns. In an effort to obtain the Brownfields
agreement, the USEPA requested additional investigation of the on-site soil and groundwater.
Subsequently in 1999, a subsurface investigation was conducted at the facility and on-site soil
and groundwater were sampled for VOCs, SVOCs, RCRA metals, and hexavalent chromium.
Analytical results indicated that all contaminants of concern (COCs) were below the regulatory

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 7
action limits in the soil samples. However, several metals, including chromium, cadmium, and lead
as well as one VOC, 2-butanone (i.e., methyl ethyl ketone (MEK)), were detected in the
groundwater at concentrations that exceeded the regulatory action limits. In 2000, a second
subsurface investigation was conducted, and on-site soil was sampled for total chromium and
toxicity characteristic leaching procedure (TCLP) chromium, and groundwater was sampled for
VOCs and RCRA metals. Soil analytical results indicated that total chromium and TCLP chromium
concentrations were either not detected or were detected below the respective regulatory action
limits. Several metals including cadmium, chromium, and lead were detected in the groundwater
sample at concentrations that exceed the current groundwater standards. A water supply well
survey was also conducted within a 0.5-mile radius of the property. No water supply wells or well
houses were identified.
Based on the analytical data from the subsurface investigations, no further action was
recommended. However, since detectable concentrations of COCs remained in on-site soils and
groundwater, a Brownfields agreement and Environmental Land Use Restriction (ELUR) were
established on October 23, 2003 and recorded with the Registry of Deeds to maintain the level
of protection appropriate for the designated current or future use of the property. According to
the most recent ELUR Update, a compliance inspection was completed on the property in January
2020. At that time, it was determined that the property was in compliance and abiding by the
restrictions set forth in the ELUR. Partner contacted the Brownfields Program Manager, Ms.
Carolyn Minnich, to obtain further information regarding the current status of this facility.
According to Ms. Minnich, no further investigation has been completed on the property since the
implementation of the 2003 ELUR and the site has been closed out.
Based on analytical data from previous subsurface investigations which confirmed impacts to the
subject property, completion of a Brownfields agreement with institutional controls, continued
compliance with the Brownfields agreement, and no further investigation required by the
overseeing agency, the residual on-site contamination associated with the adjacent Dynatech
facility represented a CREC.
2.3 Geology and Hydrogeology
Based on a review of the United States Geological Survey (USGS) Charlotte East, North Carolina Quadrangle
topographic map, the subject property is situated at elevation approximately 665 feet above mean sea level
(msl) and the local topography slopes gently towards the north-northwest. Refer to Figure 2 for a
topographic map of the site vicinity.
The subject property is situated within the Piedmont Physiographic Province, which is characterized by
gently rolling terrain and slow-flowing streams and is underlain by hard crystalline and igneous rocks that
are covered nearly everywhere by a clayey or sandy regolith consisting of weathered parent rock material
and alluvium. The uppermost geologic formation within this province is comprised of metamorphosed mafic
rock and consists specifically of metagabbro, metadiorite, and mafic plutonic-volcanic complexes.
Based on soil borings advanced during this investigation, the underlying subsurface consists predominantly
of light-brown fill material from the ground surface to approximately 2 feet below ground surface (bgs).
From 2 feet bgs to approximately 13 feet bgs, the subsurface consists of light-brown to medium-brown,
slightly sandy, clayey silt (ML). From 13 feet bgs to the terminal depth of the deepest boring (30 feet bgs),
the subsurface consists of medium-brown, slightly sandy, slightly silty clay with varying stiffness (CL). Probe

refusal (i.e., bedrock) was encountered in soil borings advanced during the investigation at depths ranging
between 6 feet bgs to 30 feet bgs. Additionally, buried construction debris consisting of remnant concrete,
asphalt, glass, lumber, and plastic was encountered in soil borings advanced on the 2207 Toomey Avenue
parcel. The debris appears to extend vertically to depths of approximately 8 feet bgs in the northern portion
of the parcel; approximately 8 feet bgs in the eastern portion, and approximately 4 feet in the western
portion of the parcel. Groundwater was encountered during this investigation at depths ranging from 5.33
feet to 24.15 feet bgs.

3.0 FIELD ACTIVITIES
Refer to Table 1 for a summary of the borings, sampling schedule, and laboratory analyses for this
investigation. The scope of the Phase II Subsurface Investigation included a geophysical survey,
advancement of four soil borings to facilitate the collection and analysis of representative soil and
groundwater samples, and installation of 10 soil gas probes to facilitate the collection and analysis of soil
gas samples.
3.1 Preparatory Activities
Prior to the initiation of fieldwork, Partner completed the following activities.
3.1.1 Permitting
In December 2020, Partner secured a Subsurface Investigation Permit (SIP No. 70002808) from the
Mecklenburg County Groundwater & Wastewater Services (GWS) Department for a previous Phase II
subsurface investigation conducted at an adjacent property (2320 Toomey Avenue). According to the
Mecklenburg County GWS, this SIP permit remains active for up to one-year and covers all investigative
fieldwork conducted at the subject property during this timeframe. Refer to Appendix A for a copy of the
SIP acquired for this investigation.
3.1.2 Utility Clearance
Partner notified North Carolina 811 to clear public utility lines as required by law at least two business days
prior to drilling activities. North Carolina 811 issued ticket numbers A210042399 and A21004242 for the
project. In addition to North Carolina 811, Partner also contracted with Delta Geophysics, Inc. (Delta) of
Charlotte, North Carolina to complete private utility clearing services in the area of the proposed soil borings
and soil gas vapor probes.
3.1.3 Health and Safety Plan
Partner reviewed the site-specific Health and Safety Plan with on-site personnel involved in the project prior
to the commencement of drilling activities.
3.1.4 Geophysical Survey
Delta conducted the geophysical survey at the subject property, under the direction of Partner on January
12, 2021. The purpose of the survey was to identify the location of former on-site septic system features
and to further clear soil borings and soil vapor probe locations of subsurface utilities. As previously
mentioned, the septic system was reportedly located on the 2301 Toomey Avenue parcel and managed
waste generated from the former Dynatech (currently Carolina Custom Tank) located at 2213 Toomey
Avenue. No information was readily available and/or ascertainable during the Phase I to indicate that the
septic system was removed.
As part of the survey, Delta systematically free-traversed suspected septic tank locations on the 2213
Toomey Avenue parcel as well as proposed boring locations with electromagnetic induction equipment, a
ground penetrating radar (GPR) unit, and utility locator with line-tracing capabilities. The equipment data
were interpreted in real time and compiled as necessary in order to identify subsurface anomalies consistent

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 10
with a septic system, disturbed soil resembling a backfilled tankhold, piping trenches, utility lines, and/or
other subsurface conduits/features. Based on the findings of the GPR survey, no anomalies indicative of a
septic system was identified on the 2213 Toomey Avenue parcel. Additionally, no subsurface utilities were
identified within the proposed soil boring and/or soil vapor probe locations.
3.2 Drilling Equipment
On January 13, 2021, Partner subcontracted with Mid-South Environmental Drilling Services, Inc. (Mid-
South) of Concord, North Carolina to provide and operate drilling equipment. Under the direction of
Partner, Mid-South advanced four soil borings and installed ten soil gas vapor probes using a direct-push,
truck-mounted Geoprobe Model 5410DT truck-mounted drill rig. The drilling rods and sampling equipment
were decontaminated between each soil boring and soil gas vapor probe location to prevent cross-
contamination.
3.3 Boring Locations
Each of the soil borings were advanced on exterior portions of the subject property. Specifically, boring B-
1 was advanced to the east of the existing on-site building on the 704 West Tremont Avenue parcel. Boring
B-2 was advanced on the 2301 Toomey Avenue parcel in an assumed hydrologically down-gradient area in
relation to the former on-site septic system. Borings B-3 and B-4 were advanced on the 2207 Toomey
Avenue parcel in the vicinity of the former on-site AST and drum storage areas.
Refer to Figure 3 for a map indicating the boring locations.
3.4 Soil Sampling
Soil borings B-1 and B-2 were overlain by topsoil and penetrated using the percussion of the direct-push
drill rig. Soil borings B-3 and B-4 were overlain by gravel and also penetrated using the percussion of the
drill rig. Soil samples were collected from each boring using a five-foot long Geoprobe® DualTube™ sampler
equipped with a five-foot long polyvinyl chloride (PVC) sample sleeve. To collect a soil sample, the sampler
was driven into the subsurface using the percussion of the direct-push drill rig. Once at the target depth,
the inner rods and sample sleeve with soils inside were removed from the ground. A new sleeve was placed
on the inner rods and the sampler was lowered inside the DualTube™ sampler to the last depth of
penetration. Once at that depth, an additional 1.25-inch drive rod and outer large rod were added, and the
sampler was advanced into the subsurface again using the percussion of the direct-push drill rig. This
process was completed until reaching the terminal depths of borings.
To inspect soil samples from each boring, a lengthwise section of each PVC liner was removed with a
splitting tool to expose the soil. The soil column was visually inspected for discoloration, monitored for
odors, and classified in accordance with the Unified Soil Classification System (USCS). Select soil sample
intervals were placed in sealable plastic bags, and field-screened for the presence of VOCs using a
photoionization detector (PID) calibrated to isobutylene. Based on PID readings, VOCs were detected in
soil samples at concentrations ranging from 0.0 parts per million (ppm) to 3.0 ppm. The soil samples
exhibiting the highest PID readings from each boring were selected for laboratory analyses.

Soil samples collected for laboratory analysis were placed into laboratory-provided sampling vials and jars,
labeled for identification, and stored in an iced cooler. Refer to the Soil Boring Logs in Appendix B for
specific soil boring details.
3.5 Groundwater Sampling
To a collect groundwater samples, drill rods were withdrawn from the subsurface of borings and a 1-inch
diameter temporary monitoring well installed within the open boreholes. Each of the temporary monitoring
wells was constructed of a pre-packed 10-foot long 0.010-inch factory-slotted PVC screen and filter sand at
the terminal end and blank PVC riser from the top of the screen interval to the ground surface. Following
pre-packed screen and riser placement, additional clean filter sand was installed within the annular space
surrounding the PVC risers to the ground surface.
Prior to groundwater sample collection, the depth to groundwater was measured in each temporary well
using an electronic water level indicator. Based on depth to water (DTW) measurements, groundwater
beneath the subject property ranged from 5.33 to 24.15 feet bgs. Following DTW measurements, a
groundwater sample was retrieved from each temporary monitoring well using new, dedicated polyethylene
tubing fed through a peristaltic pump and conveyed into laboratory-provided sampling vials and jars. The
sample vials and jars were filled with no observable headspace or air bubbles to minimize the potential for
volatilization, labeled for identification, and stored in the iced cooler.
The Soil Boring Logs in Appendix B provide temporary monitoring well construction details and measured
groundwater elevation data. Refer to Figure 3 for temporary monitoring well locations.
3.6 Soil Gas Probe Locations
Three soil gas probes (MSG-1, MVSG-1, and MVSG-2) were installed on exterior portions of the 704 West
Tremont Avenue Parcel. Specifically, soil gas probe MSG-1 was installed on the exterior northeast portion
of the 704 Tremont Avenue parcel within the footprint of a proposed building. Soil gas probe MVSG-1 was
installed on the exterior northeast side of the existing on-site 704 West Tremont Avenue building within a
grassed area and soil gas probe MVSG-2 was installed on the exterior south side of the existing on-site 704
West Tremont Avenue building within a gravel-paved parking lot area.
Five soil gas probes (MSG-2, MSG-3, MVSG-5, MVSG-6, and MVSG-7) were installed on exterior portions of
the 2207 Toomey Avenue Parcel. Specifically, soil gas probe MSG-2 was installed on the exterior northeast
portion of the 2207 Toomey Avenue parcel within a grassed area and soil gas probe MSG-3 was installed
on the exterior southwest portion of the parcel within a grassed area. Soil gas probe MVSG-5 was installed
in the western portion of the 2207 Toomey Avenue parcel within a grassed area and MVSG-6 was installed
in the northwest portion of the parcel within a grassed area. Soil gas probe MVSG-7 was installed in the
northern portion of the 2207 Toomey Avenue parcel comprising subject property within a grassed area.
One soil gas probe (MVSG-4) was installed on the 2301 Toomey Avenue parcel, with this probe installed in
the central portion of the parcel in an assumed hydrologically down-gradient area in relation to the former
on-site septic system. Additionally, one soil gas probe (iMVSG-3) was installed on the 2315 Toomey Avenue
parcel, with this probe installed on the exterior northeast side of the existing on-site building within a
grassed area.

Refer to Figure 3 for soil gas probe sample locations.
3.7 Soil Gas Sampling
Soil gas probes were overlain with either topsoil or gravel and penetrated using the percussion of the drill
rig. Due to early probe refusal and/or shallow groundwater, each of the soil gas probes was advanced to a
terminal depth of approximately 5 feet bgs. Three of the soil gas probes (namely MSG-1 through MSG-3)
were installed to facilitate collection and analysis of methane soil gas samples. The remaining soil gas
borings (MVSG-1 through MVSG-7) were installed to facilitate collection and analysis of both methane and
VOC soil gas samples.
Prior to collecting methane soil gas samples, static and differential pressure levels were measured within
soil gas probe holes using a Landtech Gem 2000 Plus landfill gas meter. Based on field measurements,
static pressures in soil gas probes ranged from 0.0 to 0.1 inches of water (inH20) and differential pressures
ranged from 0.021 to 0.035 in H20. The barometric pressure was recorded at 29.7 inches of mercury.
Following initial pressure measurements, each soil gas probe was checked for leaks, purged, and allowed
to equilibrate for approximately 30 minutes before collecting methane soil gas samples. After equilibration,
stabilized (i.e., peak) concentrations of methane were collected from each soil gas probe. Based on readings,
no methane was detected above background conditions (0 parts per million per volume - ppmv) .
Following methane concentration measurements, soil gas samples were collected from each probe location
using 1-liter, stainless-steel, cylindrical SUMMA canisters. The sampling containers were provided by Pace
Analytical Services, Inc. (Pace), a state-certified laboratory (NC Certification No. 5342), located in
Huntersville, North Carolina, which subjected each canister to a rigorous cleaning process using a
combination of dilution, heat, and high vacuum. After cleaning, the canisters were batch certified to be free
of target contaminants to a specified reporting limit via gas chromatography/mass spectroscopy prior to
delivery.
Each of the SUMMA canisters was fitted with stainless-steel flow controllers, which Pace calibrated to
maintain constant flow (approximately 0.2 liter per minute) for approximately 5 minutes of sampling time.
After installation, the soil gas probes and sample tubing were purged of ambient air using a negative
vacuum pump. Once the probe and sample tubing were purged, the sampling canister was attached directly
to the tubing and the port valve was opened, causing air to enter the sample containers due to the pressure
differential. Partner closed the valves of canisters after approximately 5 minutes of sample time. Each of
the SUMMA canisters was labeled for identification and stored away from direct sunlight prior to laboratory
analysis.
3.8 Post-Sampling Activities
Following sampling activities, the temporary monitoring wells were removed from the subsurface and each
boring and soil gas probe hole was backfilled with hydrated bentonite chips and capped with either topsoil
or gravel to match the existing ground cover. No significant amounts of derived wastes were generated
during this investigation.

4.0 LABORATORY ANALYSIS
4.1 Laboratory Analysis
A total of four soil samples (B-1 through B-4), four groundwater samples (B-1GW through B-4GW), three
methane soil gas samples (MSG-1, MSG-2, and MSG-3), and seven methane/VOC soil gas samples (MVSG-
1 through MVSG-7) were collected from the subject property. The soil and groundwater samples were
transported on January 14, 2021 in an iced cooler under chain-of-custody protocol to Pace for chemical
analysis of VOCs, SVOCs, and Resource Conservation and Recovery Act (RCRA) metals (RCRA 8 Metals) in
accordance with EPA Methods 8260D, 8270E, and 6010/7471, respectively. Additionally, the soil and
groundwater samples were analyzed for hexavalent chromium in accordance with EPA Method 7196A. The
soil gas samples were transported on January 14, 2021 in a cardboard box under proper chain-of-custody
protocol to Pace for chemical analysis of VOCs in accordance with EPA Method TO-15 and methane in
accordance with EPA Method D1946. Due to a laboratory error, the soil gas samples were only analyzed for
VOCs; methane was not analyzed.
The laboratory analytical results are included in Appendix C and discussed below.
4.2 Regulatory Agency Guidance
The NCDEQ - Inactive Hazardous Sites Branch (IHSB) has established guidelines that outline the minimal
technical and administrative procedures for all site assessments and corrective actions (i.e. cleanups)
conducted pursuant to the Inactive Hazardous Response Act of 1987 (NCGS 130A-134, et al.). The purpose
of these guidelines is to provide remediating parties guidance in performing successful remedial actions at
sites under jurisdiction of the IHSB. The guidelines also establish remedial goals for unrestricted land use at
sites with confirmed releases. The agency has two preliminary soil remediation goals (PSRGs): “health-
based” remediation goals (i.e., Residential and Industrial/Commercial) for total concentration of
contaminants and “protective of groundwater” remediation goals for leachable concentrations of
contaminants. According to the IHSB, remedial actions performed at hazardous substance-impacted sites
must attain both soil remediation goals. Based on the current use of the subject property, the concentrations
detected in soil samples were compared to the Industrial/Commercial PSRGs. Additionally, soil samples
were compared to their more stringent Residential and Protection of Groundwater PSRGs. As necessary,
Partner also compared certain RCRA metal concentrations detected in soil samples to regional background
metal ranges in soil for North Carolina from the publication Element Concentrations in Soils and Other
Surficial Materials of the Conterminous United States (Shacklette, et al., 1971).
The 15A North Carolina Administrative Code (NCAC) 2L Groundwater Standards and Gross Contaminant
Levels (GCLs) were established by the NCDEQ to protect groundwater quality of the State of North Carolina.
The 2L groundwater standards represent the maximum allowable concentrations of contaminants in
groundwater that may be tolerated without causing a threat to human health or rendering the groundwater
unsuitable for use as a drinking water source. The GCLs are levels of groundwater contamination that exceed
1,000 times the federal drinking water standard set forth in 40 CFR 141 and are calculated using risk-based
corrective action (RBCA) criteria. The 2L standards and GCLs are applicable to residential, commercial, and
industrial sites.

Phase II Subsurface Investigation Report
Project No. 20-296889.3

The NCDEQ – Division of Waste Management (DWM) has also established guidelines for vapor intrusion
into residential and non-residential structures from VOC-impacted soil and groundwater sources. The
purpose of these guidelines is to serve as a guidance tool for the investigation, evaluation, remediation, and
mitigation of vapor intrusion into building structures from chlorinated solvent and petroleum-contaminated
subsurface media. The guidelines also establish a two-tiered approach with respective concentration-based
screening levels to protect indoor air quality and serve as a cleanup standard for sites with VOC releases.
This tiered approach is outlined in the NCDEQ document entitled NCDEQ Risk Calculator User Guide dated
May 2019 and employs Vapor Intrusion Screening Levels (VISLs) and Soil Gas Screening Levels (SGSLs)
provided in the NCDEQ - DWM VISL Risk Calculator (July 2020 version).
• Initial Screening Tier – The exercise for the initial screening tier is limited to a direct comparison
of measured contaminant concentrations to the generic-based NCDEQ Residential and Non-
Residential VISLs- July 2020 (based on May 2020 USEPA Reginal Screening Tables). If measured
concentrations are above the generic-based NCDEQ Residential and Non-Residential VISLs and/or
SGSLs, then a secondary screening tier is recommended.
• Secondary Screening Tier – The secondary screening tier involves the utilization of the NCDEQ
Risk Calculator which allows for the generation of site-specific screening/cleanup levels by use of
generic/default parameters or the input of site-specific parameters (with rational/justification
documented). The use of the NCDEQ Risk Calculator and its resulting site-specific
screening/cleanup levels (with impute parameters subsequently approved/substantiated by
NCDEQ) is the outlined and acceptable NCDEQ-DWM method.
The NCDEQ - DWM provides residential and non-residential standards using a lifetime target cancer risk
(TCR) of 10-6 and a Target Hazard Quotient (THQ) of 0.2 as a default exposure scenario. Given the current
commercial use of the subject property, Partner compared soil gas sample analytical results to the generic-
based Non-Residential Sub-Slab and Exterior SGSLs provided in the July 2020 version of the NCDEQ VISL
Risk Calculator (Initial Screening Tier). Additionally, given the potential future multifamily residential use of
the subject property, soil gas samples were also compared to the more stringent generic-based Residential
Sub-Slab and Exterior SGSLs provided in the NCDEQ Risk Calculator. The risk calculator also generates
target non-residential as well as residential indoor air screening levels (IASLs) for comparison purposes and
to further evaluate site-specific VI pathways. The NCDEQ SGSLs, VISLs, and IASLs are based on the EPA’s
May 2020 Regional Screening Level (RSL) Tables.
4.3 Soil Sample Data Analysis
VOCs were not detected above the laboratory method detection limits (MDLs) in soil samples collected
from borings B-2, B-3, or B-4. Six VOCs were detected above the MDLs in the soil sample collected from
boring B-1, sample B-1(4’). None of the VOCs detected in soil sample B-1(4) exceeded the Protection of
Groundwater PSRGs, Residential PSRGs, or Industrial/Commercial PSRGs.
SVOCs were not detected above the MDLS in the soil samples collected from borings B1, B-3, or B-4.
Fourteen SVOCs were detected above the MDLs in the soil sample collected from boring B-2, B-2(4’). Of the
detected SVOCs, three (benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene) exceeded the
Residential and Protection of Groundwater PSRGs but did not exceed the Industrial/Commercial PSRGS.

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 15
between five and eight of the RCRA 8 metals were detected in each soil sample at concentrations above
their MDLs. , Of these, the arsenic concentrations detected in the soil samples from borings B-1 and B-2
exceeded the Residential PSRG, and the chromium concentrations detected in each soil sample exceeded
the Residential and Industrial/Commercial PSRGs. However, detected concentrations were within published
background concentrations. Concentrations of the other RCRA 8 Metals did not exceed their Residential,
Industrial/Commercial, or Protection of Groundwater PSRGs.
Refer to Table 2 for a summary of the soil sample laboratory analysis results.
4.4 Groundwater Sample Data Analysis
VOCs were not detected above the MDLs in the groundwater samples collected from borings B-3 (B-3GW)
and B-4 (B-4GW). The VOCs acetone and 2-hexaxnone were detected above the MDL in the groundwater
sample from boring B-1 (N-1GW) and the VOC toluene was detected above the MDL in the groundwter
sample collected from boring B2 (B-2(GW). All detected VOC concentrations are below the 2L Standards
and GCLs.
SVOCs were not detected above the MDLs in groundwater samples B-3GW and B-4GW. The SVOC benzyl
alcohol was detected in groundwater sample B-1GW and the SVOCs fluoranthene and pyrene were detected
in groundwater sample B-2GW. All detected SVOC concentrations are below the 2L Standards and GCLs.
Up to four of the RCRA 8 metals were detected above the MDLs in each of the groundwater samples. Of
these, the concentrations of chromium in groundwater samples B-2GW and B-4GW exceeded the 2L
Standards, and the concentration of lead in groundwater sample B-4GW also exceeded the 2L Standard.
GCLs have not been established for detected metals. Hexavalent chromium was not detected above the
MDLs in the groundwater samples.
Refer to Table 3 for a summary of the groundwater sample laboratory analysis results.
4.5 Soil Gas Sample Data Analysis
Thirty-four VOCs were detected in the soil gas samples above their respective laboratory MDLs. Of these,
the concentration of 1,3-butadiene in six soil gas samples (MVSG-2, MVSG-3, MVSG-4, MVSG-5, MVSG-6,
and MVSG-7) exceeded the Residential SGSLs, and the concentrations in samples MVSG-5 and MVSG-6
exceeded the Non-Residential SGSLs. The concentrations of vinyl chloride, benzene, and styrene also
exceeded the Residential SGSLs in soil gas sample MVSG-6, with the benzene concentration also exceeding
the Non-Residential SGSL. None of the other detected VOCs exceeded their Residential or Non-Residential
SGSLs.
Refer to Table 4 for a summary of the soil gas sample laboratory analysis results.
4.6 Discussion
4.6.1 Soil Analytical Results
Given the presence of SVOCs in subsurface soil at concentrations above their laboratory PSRGs (specifically
at boring location B2, near the former septic system), it appears that the subject property has been impacted
by historical on-site operations at concentrations that exceed regulatory thresholds. As such, further
investigation may be required to evaluate the detected SVOCs. .

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 16

Although arsenic and chromium concentrations in on-site subsurface soil exceeded their regulatory
standards, these COCs were detected within their naturally-occurring/background concentrations, which in
North Carolina can range from 0.1 to 73 milligrams per kilogram (mg/kg) for arsenic and 1.0 mg/kg to 1,000
mg/kg for chromium. Shacklette, et al. (1971) also reported that the findings of other researchers have
shown that the distribution of arsenic and chromium concentrations in soils can be even higher within the
Piedmont Physiographic Province of North Carolina when compared to the conterminous United States.
Under current NCDEQ guidelines, naturally-occurring constituents in soil and/or groundwaters of the State
do not constitute a violation of regulatory standards even if their naturally-occurring concentrations are
higher than North Carolina action levels. Therefore, the presence of arsenic and chromium in soil samples
is considered to be naturally-occurring and not indicative of a release or release(s) from historical and/or
current on-site operations. As such, Partner does not recommend further investigation with respect to
metals in soil at this time. However, if the subject property is entered into a regulatory program such as the
Brownfield Program, additional evaluation may be required.
As buried construction debris consisting of remnant concrete, asphalt, glass, lumber, and plastic was
encountered in soil borings advanced on the 2207 Toomey Avenue parcel, it may also be necessary to
further evaluate the extent and nature of the debris. The horizontal extent of the buried debris on this parcel
is unknown; however, the debris appears to extend vertically to depths of approximately 8 feet bgs in the
northern portion of the parcel; approximately 8 feet bgs in the eastern portion, and approximately 4 feet in
the western portion of the parcel.
4.6.2 Groundwater Analytical Results
Given the presence of VOCs and SVOCs in groundwater samples at concentrations above their laboratory
MDLs, it appears that groundwater beneath the subject property has been impacted by either historical on-
site operations or an adjacent off-site release. However, since none of the detected concentrations
exceeded their 2L standards and/or GCLs, it does not appear that VOC and SVOC impacts exceed regulatory
thresholds. As such, Partner recommends no additional investigation of VOC and/or SVOC groundwater
impacts at this time. However, if the subject property is entered into a regulatory program such as the
Brownfield Program, additional evaluation may be required. The elevated chromium and lead
concentrations detected in groundwater samples B-2GW and B-4GW may also require additional
evaluation.
4.6.3 Soil Gas Analytical Results
Although the VOC 1,3-butadiene was detected above its Residential and Non-Residential SGSLs in soil gas
samples, the presence of this analyte in soil gas is typically the result of the direct-push drilling technique
used to install temporary soil gas probe points. Specifically, the friction from drilling through tight
formations is believed to heat-up o-rings and other components on the drill rig, which results in emissions
of 1,3-butadiene. The analyte also has a relatively short-half life in the environment and does not persist in
soil; therefore, the compound is not typically detected during follow-up testing. Given these mitigating
factors, the presence of 1,3-butadiene in soil gas is likely an artifact of either the drilling process or

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 17
laboratory analysis process. As such, Partner recommends no further investigation of this compound in soil
gas at this time.
Given that benzene, ethylbenzene, and vinyl chloride were detected in soil gas samples at concentrations
above either their Residential SGSLs (initial screening tier), Partner performed the secondary screening tier,
as outlined in the NCDEQ Risk Calculator User Guide. As part of the secondary screening tier, the maximum
concentrations of each contaminant were entered into the NCDEQ Risk Calculator to further evaluate vapor
intrusion (VI) and potential human health risk to on-site future residents and workers. The risk calculator
uses default and site-specific data to compute sitewide cumulative carcinogenic risk values using current
and future residents and non-residential worker scenarios. In addition to cumulative risk assessment, the
calculator also assesses carcinogenic risk for individual constituents of concern and computes calculated
indoor air concentrations and target indoor air concentrations for carcinogens and non-carcinogens using
a TCR of 10-6 and THQ of 0.2 as a default exposure scenario. The calculator also generates calculated
carcinogenic risk and non-carcinogenic hazardous quotient values as well as IASLs for comparison purposes.
Refer to Appendix D for default and site-specific data inputs for the NCDEQ Risk Calculator.
The VI exposure pathway scenarios evaluated during this investigation included: Groundwater to Indoor Air;
Soil Gas to Indoor Air; and Indoor Air for resident and non-residential worker receptors. The Groundwater
to Indoor Air scenario evaluates the VI exposure pathway from groundwater directly to indoor air. The Soil
Gas to Indoor Air scenario evaluates the VI pathway from soil gas to indoor air and the Indoor Air scenario
evaluates VI exposure pathway directly to indoor air.
The Soil Gas to Indoor Air vapor intrusion exposure scenario was specifically evaluated for the purpose of
this investigation. Based on data input into the NCDEQ Risk Calculator and computed risk values, the
individual and cumulative carcinogenic risks for benzene, ethylbenzene, and vinyl chloride were not
exceeded at the subject property (Refer to Appendix D Output Form 1A Column 5). Therefore, the identified
on-site soil gas concentrations do not appear to represent a health risk to on-site future residents and/or
construction workers. However, if the subject property is entered into a regulatory program such as the
Brownfield Program, additional evaluation may be required.

5.0 SUMMARY AND CONCLUSIONS
Partner conducted a Phase II Subsurface Investigation at the subject property to evaluate potential impacts
of VOCs, SVOCs, metals, and/or methane to soil gas, soil, and/or groundwater as a consequence of a release
or releases from documented off-site adjacent releases and on-site historical operations. Additionally, the
purpose of the investigation was to evaluate the suitability of the subject property for potential multifamily
development through the North Carolina Brownfields Program. The scope of the Phase II Subsurface
Investigation included a geophysical survey; advancement of four soil borings to facilitate the collection
and analysis of representative soil and groundwater samples; and installation of 10 soil gas probes to
facilitate the collection and analysis of soil gas samples. Each of the soil and groundwater samples were
analyzed for VOCs, SVOCs, RCRA 8 Metals, and hexavalent chromium. The soil gas samples were analyzed
for VOCs.
Based on borings advanced during this investigation, the subsurface lithology consists of silty clay fill
material from the ground surface to approximately 2 feet bgs followed by slightly clayey, slightly sandy, silt
to approximately 13 feet bgs and slightly sandy, slightly silty clay with varying stiffness to terminal depths
of 30 feet bgs. Probe refusal (i.e., bedrock) was encountered in soil borings advanced during the
investigation at depths ranging between 6 feet bgs to 30 feet bgs. Additionally, buried construction debris
consisting of remnant concrete, asphalt, glass, lumber, and plastic was encountered in soil borings advanced
on the 2207 Toomey Avenue parcel. The debris appears to extend vertically to depths of approximately 8
feet bgs in the northern portion of the parcel; approximately 8 feet bgs in the eastern portion, and
approximately 4 feet in the western portion of the parcel. Groundwater was encountered during this
investigation at depths ranging from 5.33 feet to 24.15 feet bgs.
Based on the findings of this investigation, Partner concludes the following:
Soil
No VOCs were detected in the subsurface soil at the subject property at concentrations above their
regulatory standards. The SVOCs benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene were
detected above their PSRGs. Arsenic and chromium were also detected above their PSRGs, but within
published background concentrations.. If the subject property is entered into a regulatory program such as
the Brownfield Program, additional evaluation may be required.
As buried construction debris consisting of remnant concrete, asphalt, glass, lumber, and plastic was
encountered in soil borings advanced on the 2207 Toomey Avenue parcel, it may also be necessary to
further evaluate the extent and nature of the debris. The horizontal extent of the buried debris on this parcel
is unknown; however, the debris appears to extend vertically to depths of approximately 8 feet bgs in the
northern portion of the parcel; approximately 8 feet bgs in the eastern portion, and approximately 4 feet in
the western portion of the parcel.
Groundwater
No VOCs and/or PAHs were detected in the groundwater beneath the subject property at concentrations
above their regulatory standards. However, the metals chromium and lead were detected in groundwater
at concentrations above their 2L groundwater standards but below their GCLs. If the subject property is

Phase II Subsurface Investigation Report
Project No. 20-296889.3
January 25, 2021
Page 19
entered into a regulatory program such as the Brownfield Program, additional evaluation may be required.
The elevated chromium and lead concentrations detected in groundwater samples B-2GW and B-4GW may
also require additional evaluation.
Soil Gas
VOCs were detected in soil gas at the subject property, with 1,3-butadiene, benzene, ethylbenzene, and
vinyl chloride detected at concentrations exceeding either their Residential SGSLs and/or Non-Residential
SGSLs established by the NCDEQ. The presence of 1,3-butadiene in soil gas is typically the result of the
direct-push drilling technique and is; therefore, likely an artifact of either the drilling process or laboratory
analysis process. As such, Partner recommends no further investigation in relation to this compound in soil
gas at this time.
Since benzene, ethylbenzene, and vinyl chloride were detected in soil gas samples at concentrations above
either their initial screening tier/generic-based Residential and/or Non-Residential SGSLs, these COCs were
further evaluated using a secondary screening tier, as outlined in the NCDEQ Risk Calculator User Guide.
The maximum concentrations of each contaminant were entered into the NCDEQ Risk Calculator to further
evaluate VI and potential human health risk to on-site future residents and workers. Based on data input
into the NCDEQ Risk Calculator and computed risk values, individual and cumulative carcinogenic risks for
benzene, ethylbenzene, and vinyl chloride were not exceeded at the subject property. Therefore, the
identified on-site soil gas concentrations do not appear to represent a health risk to on-site future residents
and/or construction workers. However, if the subject property is entered into a regulatory program such as
the Brownfield Program, additional evaluation may be required.
Brownfields Suitability
Based on the analytes detected in soil, groundwater, and soil gas on the subject property, as well as potential
contaminant migration from adjacent properties, it is likely that the subject property would be considered
eligible for enrollment in the North Carolina Brownfields Program.

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.

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.
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
J The identification of the analyte is acceptable; the reported value is an estimate.
