1.0 EXECUTIVE SUMMARY
True North Consultants, Inc. (True North) has prepared this summary report for the Village of
Mount Prospect (Village) to document the findings of a limited Phase II Environmental Site
Assessment (ESA) performed at the Formula Automotive, an automotive repair property, located
at 310 West Northwest Highway in Mount Prospect, Cook County, Illinois (Site) as part of the
environmental due diligence process. The Site location and approximate boundaries are depicted
on Figures 1 and 2.
The intent of these limited investigation activities was to evaluate the Site for potential presence
of environmental impacts considering the recognized environmental conditions (RECs) identified
during the Phase I ESA prepared by True North in February 2024. The Phase I ESA identified a
total of five RECs for the Site which generally included historic and current automotive repair
operations, historic filling station operations, which was also associated with unresolved Leaking
Underground Storage Tank (LUST) incidents, and open SRP status reported on the Site. Based
on the Phase I ESA findings, which are further detailed in Section 2.0, True North was requested
to perform a subsurface investigation at the Site to evaluate subsurface conditions with respect
to the identified RECs.
Ground penetrating radar (GPR) screening was conducted as part of the limited Phase II ESA
activities to clear proposed sample locations of utilities and identify subsurface anomalies
potentially indicative of USTs. Based on the identified RECs and information obtained during the
Phase I ESA, the west portion of the Site was chosen for GPR investigation in an attempt to
identify potential USTs. The GPR survey did not identify any anomalies or indications of
disturbed/excavated areas potentially associated with potential USTs.
True North mobilized to the Site on March 20 and 21, 2024 and advanced a total of six (6) soil
borings and installed three (3) temporary groundwater monitoring wells and seven (7) soil gas
probes. The investigation was performed to evaluate soil, groundwater, and soil gas conditions at
the Site and determine the potential impact of the identified RECs. The soil borings were
advanced at strategic locations across the Site and east adjoining properties to depths ranging
between 8 to 30 feet below ground surface, dependent upon localized geologic conditions and
boring location. Boring spacing, depth, and location were determined based on current Site
conditions and findings of the Phase I ESA. One representative soil sample was collected for
laboratory analyses from each soil boring.
During the investigation, three (3) soil borings were completed as temporary groundwater
monitoring wells for the collection of representative grab groundwater samples. The temporary
groundwater monitoring well locations were selected based on the subsurface conditions
encountered during drilling as well as the RECs being evaluated. Groundwater accumulated
within each of the three groundwater monitoring wells. A grab groundwater sample was collected
from each location for laboratory analyses of select contaminants of concern.
Additionally, seven (7) soil gas probes were installed to approximately 3-4 feet below ground
surface (bgs) for the collection of representative soil gas samples for evaluation of the indoor and
hfarrnula6\ufcaltcpalrFli'upuly..I.iii111c"rahlhi: a 11 [�anvh'onnnon[al ' Ic,, Assusarricwil: 1
outdoor inhalation exposure routes. The soil gas probe locations were determined based on
current Site conditions and findings of the Phase I ESA. A soil gas sample was collected from
each soil gas probe location for laboratory analyses of volatile chemicals.
The soil, groundwater, and soil gas samples collected during the investigation were analyzed for
a strategic combination of Volatile Organic Compounds (VOCs), Volatile Chemicals (VCs),
Polynuclear Aromatic Hydrocarbons (PNAs), Resource Conservation and Recovery Act (RCRA)
Metals/Barium and pH to assess contaminants of concern generally associated with the identified
RECs. The analytical parameters were determined based on the boring/well location with respect
to the identified RECs, site conditions, regulatory and industry standards. Soil, groundwater, and
soil gas analytical results were compared to the most stringent Tier I Remediation Objectives
(ROs) listed in 35 Illinois Administrative Code (IAC) Part 742 "Tiered Approach to Corrective
Action Objectives" (742) to provide a conservative evaluation of the investigation results. The
laboratory analytical results for the soil, groundwater, and soil gas samples are summarized in
tabular format and compared to the Tier I ROs for residential properties (most conservative
remediation objectives) in Tables 1 through 7.
Soil analytical results from this investigation indicate that concentrations of VOCs, PNAs, and
RCRA Metals/Barium were below the most stringent Tier I SROs provided in 742, with the
exception of VOC constituents benzene and xylenes (total) at sample locations SB -2 and SB -5.
The concentration of xylenes (total) exceeded the Tier I SROs for the construction worker
inhalation pathway at SB -2 and SB -5. Concentrations of benzene exceeded the residential Tier I
SROs for soil inhalation, construction worker inhalation, and SCOG exposure pathways at SB -2.
Soil sample SB -5 contained concentrations of benzene in exceedance of SCOG exposure
pathways. The soil results and exceedances identified during the course of the investigation are
detailed within Section 6.1 of the subject report.
During soil screening activities, noteworthy observations were encountered at three borings
during the investigation. Visual evidence of impact (e.g. staining) and/or odors were not identified
at any of the boring locations with the exception of soil borings SB -2, SB -5, and SB -6. Elevated
PID readings were not identified at any of the boring locations with the exception of soil borings
SB -2, SB -5, and SB -6. The PID readings and field screening observations are identified on the
soil borings logs provided in Appendix A.
Grab groundwater samples were collected from temporary groundwater monitoring wells installed
at three locations across the Site based on the identified RECs and subsurface conditions
encountered during drilling. Groundwater analytical results from this investigation indicate that
concentrations of VOCs, PNAs, and RCRA Metals were below the most stringent Class I Tier I
CROs provided in 742. The groundwater results identified during the course of the investigation
are detailed within Section 6.2 of the subject report.
Soil gas probes were installed across the Site at representative locations based on the identified
RECs for collection of grab soil gas samples. Analytical results from the investigation indicated
that concentrations of VCs exceeded the most stringent Tier I SGROs at soil gas locations SG -2
and SG -7. The concentration of one or more VCs exceeded the residential Tier I SGROs
Fc rnula Alflo I"'Icp ali Fliralpu'lly -- 1.iii111c"F111"as , 11 I:anvnr„arannonlal'Ic,, Assosarricwil 2

N
established in 742 for the indoor inhalation exposure pathway at SG -7. The concentration of one
or more VCs exceeded the industrial/commercial and/or residential Tier I SGROs established in
742 for the indoor exposure pathways at SG -2. The soil gas results and exceedances identified
during the course of the investigation are detailed within Section 6.3 of the subject report.
The soil analytical results indicate that further evaluation and/or consideration is warranted for the
soil inhalation, SCOL, and construction worker inhalation exposure pathways. The groundwater
and soil gas conditions, along with the analytical results, warrant further evaluation of the indoor
inhalation exposure pathway. Exceedances for the indoor inhalation exposure pathway were
identified with the footprint of the existing on-site building and within east adjoining property
parking lot. Implementation of a Building Control Technology meeting IEPA requirements should
be considered for any current and future on-site structures considering the available information
and data. The IEPA might require an Environmental Land Use Control (ELUC) for the east
adjoining property, which could restrict the future use of the property to industrial/commercial uses
to manage potential vapor intrusion risks. Generally, the groundwater ingestion pathway can be
eliminated from consideration through implementation of a groundwater use restriction
institutional control as prescribed by the IEPA in 35 IAC 740 and 35 IAC 742. Currently, the site
is provided potable water through the municipal supply system and potable groundwater wells
have not been identified at the Site. Furthermore, an engineered barrier, such as a cap comprised
of pavement or clean fill, to mitigate soil exceedances should be considered for the Site.
The RECs identified in the Phase I ESA have been evaluated during the course of the subject
limited Phase II ESA. The associated endangerment assessment identified exceedances of the
Tier I ROs for soil and soil gas associated with various exposure pathways as provided in 742.
Based on these results, impact associated with the RECs has been identified at the Site and
further consideration and/or evaluation is warranted.
The intent of this limited investigation was to provide environmental due diligence documentation
to the Village. The findings and conclusions of this report are based on the six (6) soil borings,
three (3) temporary groundwater monitoring wells, and seven (7) soil gas probes that were
installed at various representative on -Site locations as detailed within this summary report.
The information provided herein is representative of the existing conditions at the identified boring
locations. Varying subsurface conditions, inclusive of soil types, types of contaminants, and
concentrations of contaminants, may exist at other locations on -Site.

2.0 INTRODUCTION
True North was retained by the Village to perform a limited subsurface environmental investigation
to assess the RECs and evaluate the environmental status of the Site prior to potential
redevelopment. Figure 1 identifies the location of the Site and Figure 2 identifies the surrounding
land uses.
A Phase I ESA was performed at the Site by True North in February 2024. The Phase I ESA
identified the following RECs:
The western portion of the Subject Property was historically improved with a filling
station from the late 1930s through 1950. Based on review of available information
provided by the Village, the filling station consisted of a small commercial structure
with two pump islands located on its west side. Information pertaining to the associated
underground storage tank (UST) system(s) was not identified. This filling station does
not appear to have been investigated during Leaking Underground Storage Tank
(LUST) or Site Remediation Program (SRP) activities associated with the Subject
Property. Based on the time period of operations, absence of information pertaining to
UST systems, and lack of identified investigations, the original filling station on the
western portion of the Subject Property is considered a recognized environmental
condition.
The Subject Property has operated as automotive repair services since at least 1950
through the present. Previous automotive repair operations included the use of four
in -ground hydraulic lifts which were removed sometime prior to 1989 when current
ownership acquired the Subject Property. Evidence of the removed in -ground
hydraulic lifts was observed within the western and northern service bay areas of the
building. Information pertaining to the removal and/or confirmatory soil sampling
performed during removal was not identified. Current operations include the use of six
aboveground hydraulic lifts. New and used oil is stored within 55 -gallon drums, 110 -
gallon plastic totes, an approximate 100 -gallon tote, and a 300 -gallon aboveground
storage tank (AST). Oil staining was observed beneath these items. Oil staining was
also observed throughout the service bay areas where two suspect floor drains were
observed. Additionally, snowmelt on the southern exterior side of the building was
observed to have an oily sheen and was observed draining into nearby stormwater
catch basins. Based on visual observations made during the site reconnaissance,
absence of documentation related to former in -ground lift removal activities, and
duration of operations, the automotive repair operations at the Subject Property are
considered a recognized environmental condition.
The Subject Property formerly utilized a 275 -gallon used oil UST that was located
beneath the eastern portion of the building. The UST was removed in November 2000
and LUST No. 20002263 was reported. Initial confirmatory soil samples identified
volatile organic compound (VOC) impacts from the excavation above Tiered Approach
to Corrective Action Objectives (TACO) objectives applicable at the time.
Approximately 55 -cubic yards of impacted soil and native soil were excavated and an
additional soil sample was collected. Based on analytical results of the additional soil
sample, the Illinois Environmental Protection Agency (TEPA) issued a No Further
R) "2429OG
F f>rrnda Fw�Iflo'ell-1 alr Flrup rlyr .. 1. ii 11h," l h'Ii :m� 11 [:anvlrrrnri u [ rl ':,IIE. As wussir icwill: 4
Remediation letter for the incident on November 15, 2002 with no land use restrictions.
True North notes that the 2000 LUST incident was issued closure prior to current IEPA
regulations requiring evaluation of the indoor inhalation exposure pathway. Based on
regulatory closure prior to current regulatory framework requiring evaluation of the
indoor inhalation exposure pathway, closed LUST No. 20002263 is considered a
recognized environmental condition and vapor encroachment condition to the Subject
Property.
The Subject Property was formerly improved with a second filling station from 1950
through 2014. The UST basin, consisting of diesel fuel and gasoline USTs, was
located on the northern portion of the Subject, immediately west of the building. The
fueling canopy and three pump islands were located on the central portion of the
Subject Property. In 1999, an E-85 UST was installed west of the fueling canopy and
one of the pump islands was extended to accommodate dispensing. The USTs were
removed in May 2014 and LUST No. 20140459 was reported. Approximately 861.59
cubic yards of backfill was excavated and confirmatory soil samples identified "minor
residual contamination." Free product was reported on perched groundwater and
methyl tertiary butyl ether (MTBE) concentrations in groundwater exceeded Tier I
Groundwater Remediation Objectives (GROs) in March 2015. The IEPA requested
further delineation of the release; however, as of May 2016, it does not appear that
subsequent investigations to delineate contamination have been conducted nor has
the indoor inhalation exposure pathway been evaluated. To date, the LUST incident
has not been issued regulatory closure by the TEPA. Based on the detected
groundwater contamination, residual soil contamination, and lack of investigations
since at least 2015, open LUST No. 20140459 is considered a recognized
environmental condition and a vapor encroachment condition to the Subject Property.
A portion of the Subject Property was enrolled into the SRP on August 17, 2015 in an
effort to obtain a Focused No Further Remediation letter addressing VOCs, Resource
Conservation and Recovery Act (RCRA) Metals, and semi -volatile organic compounds
(SVOCs). Impacts were detected during a previous Stage 1 Investigation which
identified Light Non -Aqueous Phase Liquid (LNAPL) within subsurface media in the
northern portion of the building. Concentrations of benzene, toluene, ethylbenzene,
and xylene (BTEX) and naphthalene were detected above Tier I Soil Remediation
Objectives (SROs). Additional monitoring wells were installed in 2015 to determine
impact of LNAPL within subsurface soils beneath the building. Concentrations of
benzene, mercury, selenium, and tetrachloroethene were detected above Tier I SROs.
In Spring 2016, chemical reagent was injected into three monitoring wells to
biodegrade xylene concentrations as well as other VOC contamination. VOC
concentrations were below Tier I SROs in soil borings advanced one inch from borings
with elevated concentrations. In June 2019, a soil gas sample was collected where
tetrachloroethene concentrations were highest. Soil gas analytical results identified
tetrachloroethene concentrations exceeding IEPA Indoor Inhalation ROs. It was noted
that the building is underlain with a sub -slab membrane barrier system building control
technology (BCT); however, it was later reported that the building utilized a sub -slab
depressurization system. True North notes that evidence of this system was not
observed during the site reconnaissance. Groundwater flow direction was determined
to be towards the west; however, groundwater was not encountered during recent
investigation activities and therefore was not sampled. To address remaining impacts
Fc rnula Aulo I"'Icp air Fli,olpc"Hy -- 1.Iinnik"'d 1111"as , 11 I:anvnr„arannonlal'Ic,, Assosarricwil 5
at the Subject Property, a groundwater use restriction, industrial/commercial land use
restriction, and BCT were proposed as requirements in the No Further Remediation
letter requested. In January 2021, the IEPA rejected the Focused Site Investigation
Report/Remedial Objectives Report/Remedial Action Plan/Remedial Action
Completion Report (FSIR/ROR/RAP/RACR) indicating that contamination had not
been fully delineated, additional soil gas and/or groundwater samples should be
collected, analysis of total petroleum hydrocarbons (TPH) should be performed,
groundwater modeling for off-site impact should be calculated, etc. A Response Letter
was prepared in January 2021 which the IEPA disproved of in August 2021, stating
that further investigation and analysis is required, including modeling for potential off-
site impacts. No subsequent investigation reports or responses to the IEPA were
identified. To date, the SRP listing remains active and has not been closed via No
Further Remediation letter. Based on lack of subsequent investigations since at least
2019, exceedances of the indoor inhalation exposure pathway, and absence of
regulatory closure, the open SRP status for the Subject Property is considered a
recognized environmental condition and vapor encroachment condition to the Subject
Property.
Figure 3 identifies locations and information pertinent to the above referenced RECs. Based on
the Phase I ESA findings, the Village requested that True North assess the RECs to evaluate the
current environmental status.

4.0 TRUE NORTH SITE INVESTIGATION ACTIVITIES
4.1 Private Utility Locate and Ground Penetrating Radar Survey
Prior to subsurface activities, JULIE, the "one call" utility locate service, was contacted so
that any utilities entering the Site could be identified. Additionally, prior to subsurface
activities, Subsurface Radar Solutions, LLC (SRS) performed ground penetrating radar
(GPR) scanning at the Site for evaluation of potential existing UST(s) and to clear proposed
soil boring locations of potential utility conflict prior to drilling. Additional utility information
was provided by the Village of Mount Prospect Public Works prior to commencing drilling
activities.
GPR screening activities were completed with a GSSI SIR -3000 GPR unit with a 400mhz
antenna. Targeted areas were scanned on March 20, 2024 using a "cross and mark" method
with grid patterns approximately 24-32" on center with the intent of identifying subsurface
anomalies potentially indicative of USTs. Based on the identified RECs and information
obtained during the Phase I ESA, select areas of the Site were targeted for GPR screening
in an attempt to identify indications of potential existing or historical USTs. The GPR survey
was conducted in one distinct area in order to investigate for potential anomalies and/or
disturbance areas. The GPR scan areas, results, and interpretations are as follows:
• West section of Site: GPR scanning was performed across the west quadrant of the
Site. The survey was performed throughout this area to investigate a potential UST
based on documentation reviewed during the Phase I ESA. The GPR survey did not
identify any anomalies or indications of disturbed/excavated areas potentially
associated with an existing or historical tank.
4.2 Description of Sampling Plan
The limited subsurface investigation was performed by True North on March 20 and 21, 2024.
A Site-specific sampling plan was developed prior to mobilization to ensure that the
objectives of the investigation were achieved.
The sampling plan included the installation of soil borings and temporary monitoring wells in
the areas where the identified RECs could have impacted the Site. During the investigation
activities, True North advanced a total of six (6) soil borings. All six of the soil borings were
advanced via direct push drilling methods to depths ranging between 8 to 30 feet below
ground surface to evaluate subsurface conditions. Boring spacing was determined with the
intent of increasing the likelihood of impact detection. Three (3) of the soil borings were
ultimately completed as temporary groundwater monitoring wells for the collection of grab
groundwater samples. An additional seven (7) soil gas probes were advanced via direct push
drilling methods to a depth of 5 feet below ground surface for collection of grab soil gas
samples. Figure 4 identifies the location of the completed soil borings, temporary
groundwater monitoring wells, and soil gas probes.

The following sections describe True North's sampling methodology and field activities.
4.3 Methods of Sampling
4.3.1 Soil Sampling
All limited Phase II ESA sampling procedures were performed according to standards
set forth by the Illinois Environmental Protection Agency 35 Illinois Administrative
Code (IAC) 742, "Tiered Approach to Corrective Action Objectives (742)," United
States Environmental Protection Agency (USEPA) SW -846, "Test Methods for
Evaluating Solid Waste, Physical/Chemical Methods," ASTM E1903-19 standard,
"Standard for Environmental Site Assessments: Phase II Environmental Site
Assessment Process," and Occupational Health & Safety Administration (OSHA) 1910
Standards.
Soil sampling procedures involved the advancement of one soil boring at each
proposed location. All downhole equipment was decontaminated between each probe
point with distilled water and liquid-nox solution and distilled water rinse. All soil
cuttings were returned to the borehole of origin after limited Phase II ESA activities
were completed.
During direct push advancement, soil samples at each soil boring location were
collected continuously at two foot or two and a half foot intervals. At each interval, the
acetate sleeves were opened and a representative soil sample from each interval was
immediately placed in a zipper locked, 4 -mil plastic bag, with airspace, and allowed to
warm to ambient conditions. The soil samples were chosen for field screening and
potential laboratory analysis based on visual observations and/or noticeable odors.
The soil samples that were containerized in the plastic bags were screened with a
calibrated PID with a 10.6eV lamp to determine the presence of photoionizable vapors
that are potentially indicative of the presence of volatile compounds in the soil.
Generally, soil samples that registered the highest PID concentration were considered
for laboratory analysis. If no positive PID readings were encountered within a soil
boring, soil sample locations were based on an appropriate soil sampling depth as
determined by field screening activities as well as the associated RECs. The depth
intervals of selected soil samples were noted during soil screening activities.
Immediately following screening activities, soil samples were collected directly from
the sleeve or zip lock bag. Soil boring logs from True North's limited Phase II ESA
activities are presented in Appendix A.
Soil samples collected for VOC analyses followed SW846 Method 5035: "Closed -
System Purge -and -Trap Extraction for Volatile Organics in Soil and Waste Samples"
field preservation protocols. A power handle and syringe were utilized to fill two pre -
Fc rnula Alflo I"'Icp ali Fliralpu'lly -- 1.iii111c"F111"as , 11 I:anvnr„arannonlal': Ilr, Assosarricwil 9
weighed sodium bisulfate preserved vials and one pre -weighed methanol preserved
vial with five grams of soil. The protocol also requires collection of one additional glass
jar with soil for analysis of moisture content utilizing Method 160.3. Dependent upon
proposed analyses at a particular sample point, additional sample was containerized
as appropriate per laboratory recommendations and analytical method requirements.
Additional glass jars were filled with soil for analyses of the following parameters:
PNAs, RCRA Metals/Barium, and pH.
4.3.2 Groundwater Sampling
A total of three soil borings were completed as temporary, one -inch diameter PVC
monitoring wells. One grab groundwater sample was collected from each of the three
groundwater wells. Temporary monitoring wells TW -1, TW -2, and TW -3 were installed
to depths of approximately 29.1, 24.2, and 14.7 feet below existing ground surface,
respectively. Each well featured ten -foot screen intervals set at the noted depths. Upon
collection of the grab groundwater samples, the wells were removed, and the soil
borings were sealed by backfilling the hole with soil cuttings and bentonite to the
surface. The surface was subsequently patched to match the corresponding
surrounding grade and surface material.
Low -flow sampling techniques were utilized as feasible to collect the grab groundwater
sample from the screen point. Low -flow water sampling techniques were completed
using a Geopump Series II Peristaltic Pump with dedicated disposable polyethylene
(poly) tubing. The pump tubing was lowered into the screen point and set
approximately in the middle of the screened interval. The purpose of the tubing
placement was to minimize excessive mixing of the stagnant water in the casing above
the screen within the screened interval zone, and to minimize re -suspension of solids
which collect at the bottom of the well. The flow rate of the pump was adjusted and
monitored to ensure minimal drawdown of water column in the well.
4.3.3 Soil Gas Sampling
Seven soil gas probes (SG -1 through SG -7) were advanced to a depth of
approximately three to four feet below ground surface and finished as temporary soil
gas monitoring wells. Soil gas probes were advanced at strategic locations across the
Site to evaluate potential impact from the RECs and the inhalation exposure pathways
evaluated under 742. A six-inch soil gas implant was attached to the end of a '/4 -inch
internal diameter Teflon tubing. The soil gas implant and tubing were then lowered into
the borehole to the desired depth. The depth of the soil gas implant was checked by
lowering a standard tape measuring tip to the borehole terminus. Teflon tubing above
ground was then cut allowing approximately two (2) feet of tubing to remain above
ground. An appropriate quantity of filter packing sand was poured into the borehole to
surround the Teflon tubing at depth. Bentonite was then backfilled on top of the sand
filter pack to ground level to seal the soil gas well from ambient air.

Soil gas samples were collected with summa canisters which collect samples by
negative pressure. Prior to soil gas sampling, each soil gas well was purged and the
purge gas was screened with a PID. The PID readings are identified on the
corresponding soil gas log provided in Appendix A. A shut-in test was subsequently
performed in accordance with EPA standards and protocols. Sub atmospheric
pressure sampling uses an initially evacuated canister provided by the laboratory to
collect gas samples. A hand valve and fixed orifice are attached to the canister prior
to sampling to regulate the flow. With this configuration, a grab sample of air from the
gas well is drawn into the pre -evacuated summa canister. After the air sample was
collected, the canister valve was closed, a cap was installed, and an identification tag
was attached to the canister for transport to an accredited laboratory for analysis.
4.4 Analytical Methods
All soil, groundwater, and soil gas samples collected for laboratory analysis were placed in
laboratory provided containers, labeled, and placed in a cooler with ice (as appropriate), and
logged on a chain of custody form. Soil, groundwater, and soil gas samples were transported
under proper chain -of -custody to Sterling Labs (Sterling) located in Des Plaines, Illinois.
Sterling is an Environmental Laboratory Accreditation (NELAC) accredited laboratory. A copy
of the laboratory NELAC accreditation is presented with the laboratory analytical reports in
Appendix C.

C presents representative photographs of the limited Phase II ESA activities.
Field soil identification was used to construct soil boring logs. Surfacing materials identified
during True North's limited Phase II ESA activities generally consisted of asphalt, concrete
or topsoil and organic matter. The surfacing materials were generally underlain by variable
fill material underlain by silty clay to boring termination depths with fine sand or silt seams
encountered at various depth intervals. The subsurface geologic materials and depths
observed at each investigation location are identified and detailed on the boring logs included
in Appendix A.
The subsurface silty clay conditions were generally observed to be similar across the Site
with varying thicknesses and depth intervals of fine grain sand or silt seams, as depicted on
the enclosed boring logs. Based on the available historical information and field observations,

the soil encountered during the investigation beneath surface fill materials are presumed to
be native subsurface soils.
At four soil boring locations, specifically SB -1 through SB -4, wet conditions were observed
within localized and lenses encountered at various depths ranging from approximately 9 and
25 feet below grade. Wet conditions varied due to the localized geology and various ground
surface elevations of each boring location across the Site. A sand seam and/orwet conditions
were not observed at SB -5 and SB -6. Based on field observations and the nature of the
assessed RECs, soil borings SB -1, SB -2, SB -3 were completed as temporary groundwater
monitoring wells TW -1, TW -2, and TW -3 respectively. The following table provides
information concerning the temporary groundwater monitoring wells, evaluated parameters

Considering the observed conditions within the gauged monitoring wells, a shallow
groundwater resource appears to exist at the Site which is consistent with the general
regional hydrogeologic conditions.
Based on field observations and the nature of the assessed RECs, seven soil gas probes
were advanced. Three of the soil gas probes, identified as SG -1 through SG -3, were
advanced directly adjacent to borings SB -1 through SB -3, respectively. Soil gas probe
identified as SG -4 was advanced on the northern extent of the Site and soil gas probes SG -
5 through SG -7 were advanced off -Site on the east adjoining properties. The following table

elevated PID readings ranged from 123.2ppm to 309.6ppm at the aforementioned locations.
In addition to odors and elevated PID readings, soil borings SB -2, SB -5, and SB -6 also
contained staining.
PID readings and other notable observations are identified on the completed soil boring logs
presented in Appendix A.
During groundwater sampling activities, no visible or olfactory indications of contamination
were observed at the temporary monitoring wells. Temporary wells TW -1 and TW -3 exhibited
slight turbidity.

5.0 DATA COLLECTION QUALITY ASSURANCE
Data was collected following procedures designed to maximize data quality, quantity, and validity.
This included information regarding the organization of objectives, functional activities, and specific
sampling and analysis quality assurance (QA) and quality control (QC) procedures. The data is
designed to achieve the specific technical and data quality objectives and goals needed to identify,
and characterize potential VOC, PNA, and/or RCRA Metal contamination at the Site.
The data collected during the limited Phase II ESA activities is being used to meet the project
objectives. Sampling and quality control were designed to be consistent with United States
Environmental Protection Agency (USEPA) procedures outlined in Guidance on Systematic
Planning Using the Data Quality Objectives Process, EPA QA/G-4.
5.1 Data Quality Objectives
Data Quality Objectives (DQOs) are quantitative and qualitative statements specifying the
quality of the data required to support the decision-making process. DQOs for measurement
data are expressed in terms of accuracy, precision, completeness, representativeness, and
comparability. DQOs define the degree of the total uncertainty in the data that is acceptable
for each specific activity during environmental site assessment activities. The uncertainty
includes both sampling error and analytical error. Ideally, the prospect of zero uncertainty is
the intent; however, the variables associated with the process (field and laboratory) inherently
contribute to uncertainty in the data. It was True North's overall objective to keep the total
uncertainty within an acceptable range that would not hinder the intended use of the data. In
order to achieve the objective, specific data quality requirements such as detection limits,
criteria for accuracy and precision, sample representativeness, data compatibility and data
completeness were attempted. The overall objectives and requirements were established such
that there was a high degree of confidence in the measurements. The data collected during
this assessment is being used to address the following: VOCs, PNAs, and/or RCRA Metals
potentially present or absent in soil, groundwater, and soil gas (quantitatively).
The objectives with respect to the field investigation were to maximize the confidence in the
data. To ensure sample representativeness, sample collection was performed in accordance
with USEPA recommended procedures for the collection, preservation, and holding times
specified in EPA SW -846.
5.2 General Field Procedures
To assure that field data was collected accurately and correctly, specific standard field
procedures as outlined in SW -846 were adhered to during each sampling event.
5.2.1 Equipment & Calibration
To ensure that measurements made in the field were performed with properly calibrated
instruments, equipment was calibrated prior to each use as described in the Owner's
Manual for each instrument. Field equipment was calibrated prior to use and was
FoirnulaAu'lo FII pair Flirapuly .. I.iii111c"ah1IisAsur 11 [:anvnr„rnnnonlal Slic Assosarricni 15
%.
N
maintained in accordance with the manufacturers' specifications. In addition, prior to
and after use, each major piece of equipment was cleaned, decontaminated, checked
for damage, and repaired as needed.
5.2.2 Sample Handling
After a sample was collected, proper sample handling procedures ensured that the
sample remains representative. These procedures included:
• chain of custody;
• sample identification;
• sample packaging; and
• proper storage of the sample.
5.2.2.1 Sample Custody
Samples were collected and handled in accordance with standard USEPA
chain of custody protocols. The objective of the chain of custody was to
maintain an accurate written custody record that traced the possession and
handling of the sample from collection through analysis.
Custody is defined if a sample:
• Is in one's actual possession, (or)
• Is in one's view, after being in one's physical possession, (or)
• Is in one's physical possession and then locked away so that no one can
tamper with it, (or)
• Is kept in a secured area, restricted to authorized personnel only.
A unique identification number was assigned to each sample collected before
it was submitted for shipment to the laboratory. Sample storage and custody
was the responsibility of the field personnel. Upon laboratory receipt and
analysis of the samples, a copy of the chain of custody form was returned to
True North with the laboratory report. The chain of custody form remained with
the samples until the sample was discarded.
5.2.2.2 Sample Identification & Packing
A unique designation was used to identify individual samples for each location.
Sample identification numbers were identified in the field and were used to
identify the sample on the chain of custody form. After labels were checked,
sample jars were checked for competency and placed into coolers for return to
the laboratory for analysis.

N
5.2.3 Sample Delivery
Samples were relinquished to laboratory personnel by True North's field personnel after
sampling was completed. Upon receipt of shipment, the laboratory inspected each
sample jar or container for evidence of tampering. The laboratory sample custodian then
removed each sample jar and verified the condition of the sample and containers and
compared sample labels to the chain of custody. If any inconsistencies were observed,
they were documented on the chain of custody.
5.2.4 Decontamination Protocol
Decontamination protocols were strictly adhered to in order to minimize the potential for
cross -contamination between sample locations and contamination of areas off-site.

7.0 FINDINGS AND CONCLUSIONS
True North has prepared this summary report for the Village to document the findings of a limited
Phase II ESA performed at the Formula Automotive, an automotive repair property, located at 310
West Northwest Highway in Mount Prospect, Cook County, Illinois as part of the environmental due
diligence process. The Site location and approximate boundaries are depicted on Figures 1 and 2.
The intent of these limited investigation activities was to evaluate the Site for potential presence of
environmental impacts considering the RECs identified during the Phase I ESA prepared by True
North in February 2024. The Phase I ESA identified a total of five RECs for the Site which generally
included historic and current automotive repair operations, historic filling station operations, which
was also associated with unresolved LUST incidents, and open SRP status reported on the Site.
Based on the Phase I ESA findings, which are further detailed in Section 2.0, True North was
requested to perform a subsurface investigation at the Site to evaluate subsurface conditions with
respect to the identified RECs.
GPR screening was conducted as part of the limited Phase II ESA activities to clear proposed
sample locations of utilities and identify subsurface anomalies potentially indicative of USTs. Based
on the identified RECs and information obtained during the Phase I ESA, the west portion of the
Site was chosen for GPR investigation in an attempt to identify potential USTs. The GPR survey
did not identify any anomalies or indications of disturbed/excavated areas potentially associated
with potential USTs.
True North mobilized to the Site on March 20 and 21, 2024 and advanced a total of six (6) soil
borings and installed three (3) temporary groundwater monitoring wells and seven (7) soil gas
probes. The investigation was performed to evaluate soil, groundwater, and soil gas conditions at
the Site and determine the potential impact of the identified RECs. The soil borings were advanced
at strategic locations across the Site to depths ranging between 8 to 30 feet below ground surface,
dependent upon localized geologic conditions and boring location. Boring spacing, depth, and
location were determined based on current Site conditions and findings of the Phase I ESA. One
representative soil sample was collected for laboratory analyses from each soil boring.
During the investigation, three soil borings were completed as temporary groundwater monitoring
wells for the collection of representative grab groundwater samples. The temporary groundwater
monitoring well locations were selected based on the subsurface conditions encountered during
drilling as well as the RECs being evaluated. Groundwater accumulated within each of the three
groundwater monitoring wells. A grab groundwater sample was collected from each location for
laboratory analyses of select contaminants of concern.
Additionally, seven soil gas probes were installed to approximately 3-4 feet below ground surface
(bgs) for the collection of representative soil gas samples for evaluation of the indoor and outdoor
inhalation exposure routes. The soil gas probe locations were determined based on current Site
conditions, findings of the Phase I ESA, and off-site accessibility. A soil gas sample was collected
from each soil gas probe location for laboratory analyses of volatile chemicals.
The soil, groundwater, and soil gas samples collected during the investigation were analyzed for a

strategic combination of VOCs, VCs, PNAs, RCRA Metals/Barium, and pH to assess contaminants
of concern generally associated with the identified RECS. The analytical parameters were
determined based on the boring/well location with respect to the identified RECs, site conditions,
regulatory and industry standards. Soil, groundwater, and soil gas analytical results were compared
to the most stringent Tier I ROs listed in 742 to provide a conservative evaluation of the investigation
results. The laboratory analytical results for the soil, groundwater, and soil gas samples are
summarized in tabular format and compared to the Tier I ROs for residential properties (most
conservative remediation objectives) in Tables 1 through 7.
Soil analytical results from this investigation indicate that concentrations of VOCs, PNAs, and
RCRA Metals/Barium were below the most stringent Tier I SROs provided in 742, with the exception
of VOC constituents benzene and xylenes (total) at sample locations SB -2 and SB -5. The
concentration of xylenes (total) exceeded the Tier I SROs for the construction worker inhalation
pathway at SB -2 and SB -5. Concentrations of benzene exceeded the residential Tier I SROs for
soil inhalation, construction worker inhalation, and SCOG exposure pathways at SB -2. Soil sample
SB -5 contained concentrations of benzene in exceedance of SCOG exposure pathways. The soil
results and exceedances identified during the course of the investigation are detailed within Section
6.1 of the subject report.
During soil screening activities, noteworthy observations were encountered at three borings during
the investigation. Visual evidence of impact (e.g. staining) and/or odors were not identified at any
of the boring locations with the exception of soil borings SB -2, SB -5, and SB -6. Elevated PID
readings were not identified at any of the boring locations with the exception of soil borings SB -2,
SB -5, and SB -6. The PID readings and field screening observations are identified on the soil
borings logs provided in Appendix A.
Grab groundwater samples were collected from temporary groundwater monitoring wells installed
at three locations across the Site based on the identified RECs and subsurface conditions
encountered during drilling. Groundwater analytical results from this investigation indicate that
concentrations of VOCs, PNAs, and RCRA Metals were below the most stringent Class I Tier I
CROs provided in 742. The groundwater results identified during the course of the investigation
are detailed within Section 6.2 of the subject report.
Soil gas probes were installed across the Site at representative locations based on the identified
RECs for collection of grab soil gas samples. Analytical results from the investigation indicated that
concentrations of VCs exceeded the most stringent Tier I SGROs at soil gas locations SG -2 and
SG -7. The concentration of one or more VCs exceeded the residential Tier I SGROs established
in 742 for the indoor inhalation exposure pathway at SG -7. The concentration of one or more VCs
exceeded the industrial/commercial and/or residential Tier I SGROs established in 742 for the
indoor exposure pathways at SG -2. The soil gas results and exceedances identified during the
course of the investigation are detailed within Section 6.3 of the subject report.
The soil analytical results indicate that further evaluation and/or consideration is warranted for the
soil inhalation, SCOG, and construction worker inhalation exposure pathways. The groundwater
and soil gas conditions, along with the analytical results, warrant further evaluation of the indoor
inhalation exposure pathway. Exceedances for the indoor inhalation exposure pathway were

identified with the footprint of the existing on-site building and within east adjoining property parking
lot. Implementation of a Building Control Technology meeting IEPA requirements should be
considered for any current and future on-site structures considering the available information and
data. The IEPA might require an Environmental Land Use Control (ELUC) for the east adjoining
property, which could restrict the future use of the property to industrial/commercial uses to manage
potential vapor intrusion risks. Generally, the groundwater ingestion pathway can be eliminated
from consideration through implementation of a groundwater use restriction institutional control as
prescribed by the IEPA in 35 IAC 740 and 35 IAC 742. Currently, the site is provided potable water
through the municipal supply system and potable groundwater wells have not been identified at the
Site. Furthermore, an engineered barrier, such as a cap comprised of pavement or clean fill, to
mitigate soil exceedances should be considered for the Site.
The RECs identified in the Phase I ESA have been evaluated during the course of the subject
limited Phase II ESA. The associated endangerment assessment identified exceedances of the
Tier I ROs for soil and soil gas associated with various exposure pathways as provided in 742.
Based on these results, impact associated with the RECs has been identified at the Site and further
consideration and/or evaluation is warranted.
The intent of this limited investigation was to provide environmental due diligence documentation
to the Village. The findings and conclusions of this report are based on the six (6) soil borings, three
(3) temporary groundwater monitoring wells, and seven (7) soil gas probes that were installed at
various representative on -Site locations as detailed within this summary report.
The information provided herein is representative of the existing conditions at the identified boring
locations. Varying subsurface conditions, inclusive of soil types, types of contaminants, and

The Standard Reference Material (SRM) (Preparation Batch B24D0143) had recovery of Silver outside of
control limits (34% recovery, QC Limits 59.8-111). This SRM is associated with the following samples:
024C0848-01,02,03,04
GCMS Semivolatiles
8270 PNA SIM
024CO848-01: The internal standards chrysene-d12 and perylene-d12 recovered outside control criteria
(50% - 200% for both) at 46% and 47%, respectively.
024CO848-03: The internal standard chrysene-d12 recovered outside control criteria (50% - 200%) at
48%.
024CO848-04: The internal standards chrysene-d12 and perylene-d12 recovered outside control criteria
(50% - 200% for both) at 49% for both.
024C0848-05: The internal standard perylene-d12 recovered outside control criteria (50% - 200%) at
289%.
024CO848-06: The internal standard perylene-d12 recovered outside control criteria (50% - 200%) at
218%.
024CO848-05: The sample was utilized for MS/MSD purpose. Several analytes recovered outside
recovery criteria:
MS: Benzo(g,h,i)perylene: Recovery 37%; LCL 48%
MS: Naphthalene: Recovery 48%; LCL 69%
MS: Perylene-d-12: Recovery 228; UCL 200

B24D0225-BS1 and BSD1 had low recoveries for chloromethane at 56% and 68% below the lab control
limit with an elevated RPD of 24% for bromomethane.
024C848-05 initially was run low level and had very low internal standard recoveries below 10% and
potential loss of sample sensitivity, possibly due to reaction of sample with preservative. The sample was
re -run with the methanol vial at dilution and had acceptable recoveries. The sample is reported as low as
possible to MDL- lowest calibration point levels.
Sample 024C848-05 had 2-Hexanone reported with an "E" flag (Value above quantitation range). The
medium level dilution was below the reporting level. The detected value is reported.
