VIMS Installation Completion Report
Yandle-Witherspoon Supply, Inc.
Charlotte, North Carolina
Brownfields Project No. 24010-20-060
H&H Job No. TCR-001

1.0 Introduction

On behalf of WP Yandle, LLC (the Prospective Developer or PD), Hart & Hickman, PC (H&H)
has prepared this report to document vapor intrusion mitigation system (VIMS) installation,
influence testing, and post-construction sampling activities for the Alexan Optimist Park Phase II
Apartments multi-family development at the Yandle-Witherspoon Supply, Inc. Brownfields
Property (Brownfields Project No. 24010-20-060) located northwest of the N. Brevard Street and
Belmont Avenue intersection in Charlotte, Mecklenburg County, North Carolina (Site). The
Brownfields property consists of two contiguous parcels that total approximately 5.6 acres of land
located in a residential and commercial area of northeast Charlotte. A Site location map is provided
as Figure 1, and a Site map is included as Figure 2.

Redevelopment at the Site is underway and includes one residential apartment building which is
constructed with concrete slab-on-grade foundations and structural footings in the residential units,
with column foundations in the residential amenity space. An associated multi-level parking
garage is nearing completion to the north of the multi-family building, and later phases of
development will include an office building in the northeastern portion of the Site. The
approximate building footprints are shown on Figure 2.

To address potential environmental concerns associated with historical on-Site and nearby off-Site
operations, a portion of the Site was entered into the North Carolina Department of Environmental
Quality (DEQ) Brownfields Program and received eligibility in a letter dated April 3, 2020.
Additional portions of the Site were subsequently added to the Brownfields property and an
amended eligibility letter was issued on May 18, 2021.

Previous assessment activities were completed in various portions of the Site between 1990 and
2019. Following entry into the Brownfields program, H&H completed Brownfields assessment

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
activities for the Site in April 2021 to evaluate Site surface and subsurface conditions for potential
impacts based on data gaps identified in the previous assessment activities. Assessment activities
included collection of soil, groundwater, surface water and sediment, and soil gas samples. Data
summary tables and a sample location map for the April 2021 assessment are included in Appendix
A, and a brief summary of groundwater and soil gas sampling results is included below.

Results of groundwater assessment activities completed in the western (upgradient) and northern
(downgradient) portions of the Site identified low levels of tetrachloroethene (PCE, up to 8.9 µg/L)
at concentrations above the DEQ 15A NCAC 02L.0202 Groundwater Standard (2L Standard). In
addition, low levels of trichloroethene (TCE, up to 5.6 µg/L) were detected in the downgradient
portion of the Site at concentrations above the DEQ 2L Standard and the DEQ Vapor Intrusion
Groundwater Screening Levels (GWSLs). No other compounds were detected at concentrations
above the 2L Standards or GWSLs in the groundwater samples collected at the Site.

Results of the soil gas assessment activities completed within the footprint of proposed residential
and office buildings did not identify the presence of compounds at concentrations above the DEQ
DWM Vapor Intrusion Sub-slab and Exterior Soil Gas Screening Levels (SGSLs). Results of
cumulative risk calculations utilizing the highest concentration of any compound detected in any
soil gas sample confirm that the cumulative carcinogenic and noncarcinogenic risks are orders of
magnitude below the DEQ and EPA acceptable levels.

Although assessment results do not indicate an unacceptable vapor intrusion risk at the Site, the
PD elected to proactively install a passive VIMS in the proposed multi-family residential
apartment building during redevelopment activities as a precautionary measure. H&H prepared a
Vapor Intrusion Mitigation Plan (VIMP) which was revised on December 8, 2021 and received
DEQ approval via email on February 17, 2021. Additionally, H&H prepared a VIMP Addendum
dated March 17, 2023, which received DEQ approval via email on July 20, 2023. The DEQ-
approved VIMP includes installation of a passive VIMS in the ground floor of the multi-family
residential apartment complex and occupiable spaces in the parking garage. The VIMP Addendum
documents an alternative vapor barrier system used in the elevator pit located in the parking garage.

This report documents installation and associated testing of the VIMS for the first turn of the multi-
family residential apartment building, which includes the residential amenity area and northeastern
portions of the building, and the elevator and elevator lobby in the parking garage. Note, the
second turn of the building, which includes ground-level apartment units in the southwestern
portions of the building and parking garage stairwell, as shown in VM-3 (Appendix B), is not
included in this report. Following completion of the VIMS construction and efficacy testing in the
second turn of the building, an installation completion report will be completed and submitted
under separate cover prior to occupancy. A discussion of VIMS installation and influence testing
activities is provided in Section 2.0; a summary of VIMS effectiveness sampling activities is
provided in Section 3.0, and summary and conclusions based on the results of the VIMS
installation and effectiveness testing are provided in Section 4.0.

2.0 VIMS Installation and Influence Testing

The first phase of the Site redevelopment includes one multi-family residential apartment building
with an attached parking garage. As noted above, the VIMS was designed for installation below
Level 1 of the multi-family apartment building and select occupiable spaces in the parking garage.
A sub-slab vapor extraction system was installed below the Level 1 portions of the residential
apartment building and the occupiable spaces in the parking garage and includes a permeable
gravel layer, a horizontal sub-slab vapor collection network, vapor barrier with spray-applied
seams, riser piping, and passive ventilators. The as-built system specifications and details (VM-1
and VM-2) and the as-built drawings depicting the layout of the VIMS (VM-3) are provided in
Appendix B. Product specifications for the VIMS components are included in Appendix C and
installation photographs and the VIMS inspection log are included as Appendix D. This report
documents the first building turn, which includes the northeastern portion of the multi-family
residential apartment building and the parking garage elevator and elevator lobby. The VIMS
installation for the southwestern portion of the building, identified as the second turn, is not
included in this report and will be documented under separate cover.

2.1 VIMS Installation

During installation of the VIMS, H&H conducted inspections during various phases of
construction to confirm the VIMS was installed in accordance with the DEQ-approved VIMP and
VIMP Addendum. Inspections were completed during the following phases of installation:

(1) Inspection of the base course gravel layer, sub-slab Terravent layout, and monitoring points
prior to installation of the vapor barrier;
(2) Inspection of the Monobase vapor barrier prior to pouring concrete along with oversight of
vapor barrier smoke testing;
(3) Inspection of RetroCoat in the parking garage elevator;
(4) Inspection of above-grade vertical riser piping; and
(5) Inspection of ventilators and riser pipe connections.

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
Based on observations made during the VIMS inspections and photographs of the installation
activities, the VIMS was installed in general accordance with the DEQ-approved VIMP and VIMP
Addendum. A brief summary of the main VIMS components is provided in the following
paragraphs.

Below the slab of the building, vapor extraction is achieved through an interconnected system of
Land Science Terra Vent™, a sub-slab vapor collection mat (1-inch tall by 12” wide) which was
installed in a minimum 4-inch gravel layer beneath the building slab. The permeable gravel layer
consisting of clean #57 stone was installed beneath the entirety of the building slab to enhance
sub-slab vapor transmission and allow for air movement beneath the slab. The sub-slab vapor
collection mat is connected to 3” Schedule 40 PVC riser piping which extends vertically through
the building and discharges vapors through exhaust stacks installed above the building roofs. Aura
AV-3 PVC ventilators were installed on the discharge end of the exhaust stacks on the roofs.

The Monoshield™ vapor barrier system manufactured by Land Science was installed above the
gravel layer and beneath the concrete slab. The Monoshield™ system consists of a chemically-
resistant 30-mil, multi-layer vapor barrier (Monobase™) designed to prevent the migration of
volatile organic compounds (VOCs). The vapor barrier was installed by S&H Waterproofing
(S&H), a Land Science-certified installer, per the manufacturer’s installation instructions. Seams
within the building footprint were overlapped a minimum of 6 inches and were sealed with a 60-
mil thickness of Nitra-Core™. In areas of utility penetrations or penetration banks, a seal
consisting of two 30-mil Nitra-Core layers with reinforcement fabric installed between the layers
was cable tied to the utility to create an airtight seal.

During construction activities, Monoshield™ was not installed below the elevator pit in the
parking garage elevator. Therefore, in accordance with the DEQ-approved VIMP Addendum,
Land Science Retro-Coat™ vapor barrier system was installed by S&H, a manufacturer-certified
contractor, on the interior base and sidewalls of the parking garage elevator pit. Retro-Coat™ is
a VOC-rated engineered vapor barrier that includes a Retro-Coat Primer layer and the final Retro-
Coat layer. The Retro-Coat primer was installed to a thickness of 6-mil and allowed to dry prior
to the application of the Retro-Coat layer. The Retro-Coat “A” (modified Epoxy) and Retro-Coat
6

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
“B” (hardener blend) were mixed in the field in accordance with the Land Science installation
instructions, and the mixture was then applied over the Retro-Coat Primer to a minimum thickness
of 20-mil. During various stages of the Retro-Coat application, H&H observed the installation
and collected thickness measurements to verify installation was completed in accordance with the
manufacturer’s instructions.

Permanent and temporary monitoring points were installed during construction to allow for
influence testing and collection of sub-slab vapor samples throughout the building. The
monitoring points are constructed of either 2-inch diameter SCH 40 PVC piping or Cox-Colvin
Vapor Pins®, which were approved by the design engineer. At locations where H&H installed the
Vapor Pins® to replace the monitoring points, the monitoring points were either not installed during
the sub-slab installation activities, or were damaged during the concrete slab pour. The monitoring
point as-built details are included on Sheet VM-2, and the locations and monitoring point
construction type are shown on Sheet VM-3 (Appendix B). Specification sheets for the Vapor
Pin® device and installation instructions, which were followed for the pin installation with the
secured cover, are provided in Appendix D.

Note, the temporary monitoring points were constructed of 2-inch diameter SCH 40 PVC and were
abandoned following the influence testing (discussed in Section 3.0). However, due to the vapor
barrier modification in the elevator pit in the parking garage, temporary monitoring point TMP-4
(as identified in the DEQ-approved VIMP) was converted to a permanent monitoring point and is
identified on VM-3 in Appendix B as MP-11.

2.2 Smoke Testing and Coupon Sampling

To evaluate the vapor barrier installation and thickness prior to installation of concrete over the
vapor barrier, H&H and the manufacturer-certified installer completed smoke testing to evaluate
for potential leaks in the barrier and completed coupon sampling to measure application thickness.
The smoke testing was completed to identify areas where a patch or additional vapor barrier
application was needed to adequately seal the sub-slab. During the smoke testing, the areas where
smoke was observed were repaired by the certified installer. Following sealing of all the
7

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
penetrations and sub-slab areas, H&H completed coupon sampling following the manufacturer-
recommended frequency of a minimum of one coupon per approximately 1,000 sq ft of slab area.
The coupons were collected by cutting out an approximately 3-inch by 3-inch square (an
approximately 9 square-inch square) of the Nitra-Core™ at the Monobase seams. The coupon was
measured on all four sides of the square to evaluate whether the Nitra-Core™ was applied to the
manufacturer-recommended thickness of 60 mil. The cut area was subsequently repaired by the
manufacturer-certified installer using a patch. If the results of the coupon measurements indicated
the Nitra-Core™ was applied to a thickness less than the manufacturer-specified 60 mil, the area
represented by the coupon was resprayed with additional Nitra-Core™ to the correct thickness.

2.3 VIMS Influence Testing

Influence testing was performed to evaluate the vacuum communication beneath the slab and to
document that sufficient sub-slab depressurization can be obtained should electric fans be needed
in the future. H&H completed influence testing on January 11, 2023 and May 24, 2023. Because
the sub-slab horizontal collection network is connected between both building occupancy turns,
the influence testing was completed for the entire ground floor, including the area in the second
turn. DEQ considers 4 Pascals (Pa) or 0.016 inches water column (in-WC) differential pressure to
be the minimum vacuum needed for an active depressurization system to effectively treat potential
structural vapor intrusion.

The influence testing was completed using Festa AMG Eagle Extreme (Eagle Extreme),
RadonAway RP-265 (RP-265), and RadonAway RP-145 (RP-145) fans to model an active
depressurization system. Differential pressure measurements were collected at each vacuum
monitoring point using a Dwyer series 475 Mark III Digital manometer (capable of measuring
0.001 in-WC or 0.25 Pa) to establish baseline conditions prior to operation of the electric fans.
Following collection of baseline differential pressure measurements, the electric fans were turned
on and differential pressure measurements were collected at each monitoring point.

Final results of the influence tests indicated sub-slab vacuum measured at the monitoring points
ranged from 0.021 in-WC to 2.380 in-WC (5.22 Pa to 592 Pa) which demonstrates vacuum above

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
the DEQ minimum of 0.016 in-WC (4 Pa) can be achieved below the slab of the building. The
locations of the monitoring points are shown on VM -3 (Appendix B). The pilot test field data is
summarized in tables included as Appendix E-1 and Appendix E-2. After completion of the
influence testing activities, the temporary monitoring points were abandoned and sealed at the
finished floor grade.

3.0 Pre-Occupancy VIMS Effectiveness Sampling

Following installation of the VIMS, completion of successful influence testing, and general
enclosure of the building envelope, H&H collected sub-slab soil vapor samples in accordance with
the DEQ-approved VIMP. Seven (7) sub-slab soil gas samples were collected throughout the first
floor in the first turn area of the multi-family residential building and in the parking garage elevator
lobby. In addition, four (4) indoor air samples were collected from the first floor of the multi-
family residential building and parking garage elevator lobby concurrent with the sub-slab soil gas
samples.

The sub-slab soil gas and indoor air assessment activities were conducted in general accordance
with the DEQ-approved VIMP and the DEQ Department of Waste Management (DWM) Vapor
Intrusion Guidance (Guidance) dated March 2018. Details of the sub-slab soil vapor and indoor
air sampling activities and results are provided in the following sections.

3.1 Sub-Slab Soil Gas Sampling Methodology

On July 17, 2023, H&H collected sub-slab soil gas samples from permanent monitoring points
within the first turn area of the multi-family residential building and the parking garage elevator
lobby. The sampling was performed following VIMS installation activities and several weeks
after installation of the ventilators. The sub-slab soil gas samples were collected from permanent
monitoring points MP-3, MP-4, MP-6, MP-7, MP-8, and MP-9 in the multi-family residential
building and MP-11 in the parking garage elevator lobby. MP-11 was not included in the DEQ-
approved VIMP as a sub-slab soil gas sample location; however, a sub-slab sample gas was
collected as a conservative approach, since the Retrocoat in the elevator pit was not installed at the
time of the pre-occupancy sampling event.

For quality assurance/quality control (QA/QC) purposes, one duplicate sub-slab soil gas sample
(MP-DUP) was collected from the MP-9 location. The duplicate sample was collected utilizing a
laboratory-supplied stainless-steel sampling “T” fitting which allows for the simultaneous
collection of two sub-slab soil gas samples from a single air intake.

10

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
To collect the sub-slab soil gas samples, Teflon sample tubing was secured to a 2-inch expandable
well cap with a sampling port that was secured onto the 2-inch diameter PVC monitoring point.
For sample locations constructed with a Vapor Pin®, the Teflon sample tubing was secured to the
Vapor Pin® barb. The tubing was connected to a laboratory-supplied airflow regulator and batch-
certified 1-liter stainless steel Summa canister using a nut and ferrule assembly to create an airtight
seal. The airflow regulator was preset by the laboratory to collect a soil gas sample over an
approximate 10-minute period at a flow rate no greater than approximately 100 milliliters per
minute.

Prior to sample collection, H&H conducted a leak test at each monitoring point by placing a shroud
around the monitoring point and sampling train including the Summa canister. The air within the
shroud was flooded with helium vapor and concentrations within the shroud were measured with
a calibrated helium detector. Helium concentrations within the shroud were maintained between
approximately 9 % and 14%. A GilAir vacuum pump was connected to the sample tubing outside
of the shroud and used to purge a minimum of three volumes (monitoring point and sample train)
of soil vapor, and a sample of the purged vapor was collected into a Tedlar® bag at each sampling
point. A helium detector was used to measure helium concentrations within the Tedlar® bag
sample to confirm helium concentrations in the sample train were less than 10% of that measured
within the shroud. Results of the helium leak checks indicated that short-circuiting at the
monitoring points or within the sampling train was not present at unacceptable levels. Soil vapor
sampling field forms completed by sampling personnel are included in Appendix E.

Following successful leak checks, the airflow regulators were opened to allow collection of the
sub-slab soil gas samples. Vacuum in the Summa canisters was monitored during the sampling
event to confirm adequate sample volume was collected at each monitoring point location. Upon
completion of sample collection, the airflow regulator was closed to the Summa canister. The
canisters were labeled with the sample identification, beginning and ending times, pressure
measurements, and the requested analysis. The canisters were then placed in laboratory-supplied
shipping containers and shipped to Con-Test, a Pace Analytical Laboratory (Con-Test) under
standard chain of custody protocols for analysis of VOCs by EPA Method TO-15.

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
3.2 Sub-Slab Soil Gas Sampling Results

The sub-slab soil gas sample analytical results are summarized in Table 1 and compared to the
DEQ Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated
July 2023. The laboratory analytical report and the chain of custody record are provided in
Appendix F.

Laboratory analytical results for the first turn area of the building indicate that compounds were
detected above the laboratory method detection limits (MDLs) in each sub-slab soil gas sample.
Carbon tetrachloride was detected in sub-slab sample MP-11 at a concentration of 45 micrograms
per cubic meter (µg/m3), which exceeds the Residential SGSL of 16 µg/m3, and chloroform was
detected in samples MP-4, MP-7, MP-8, and MP-11 at concentrations ranging from 5.4 µg/m3 to
98 µg/m3, above the Residential SGSL of 4.1 µg/m3. In addition, 1,2-dibromoethane was detected
in each sub-slab sample, with the exception of MP-4, at concentrations exceeding the Residential
SGSL of 0.16 µg/m3. No other compounds were detected in the sub-slab soil gas samples at
concentrations exceeding the Residential SGSLs. Note, trichloroethene (TCE) was detected in
sub-slab soil gas sample MP-3 at a laboratory estimated (J-flag) concentration of 0.47 J µg/m3,
which is orders of magnitude below the Residential SGSL, and TCE was not detected at any other
sub-slab sample location including the adjacent monitoring points MP-4 and MP-6.

3.3 Sub-Slab Soil Gas Vapor Intrusion Evaluation

The DEQ Vapor Intrusion SGSLs are conservative and based on a Target Cancer Risk (TCR) of
1 x 10-6 and a Target Hazard Quotient (THQ) of 0.2 for potential non-carcinogenic risks. The DEQ
and EPA acceptable risk level for potential carcinogenic risks is a cumulative lifetime incremental
cancer risk (LICR) of 1 x 10-4 or less, and the acceptable level for non-carcinogenic risks is a
hazard index (HI) of 1.0 or less. The HI is the sum of the THQ for each target analyte detected in
a sample.

To further evaluate the sub-slab soil gas concentrations, H&H utilized the DEQ Risk Calculator
(July 2023) to calculate potential vapor intrusion risks for the first turn of the multi-family
12

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
residential and parking garage elevator lobby. H&H modeled a worst-case scenario for the first
turn by using the highest concentrations of any compound detected in any sub-slab soil gas sample.
Based on the planned use of the development for residential use, H&H calculated worst-case risk
assuming a residential use scenario. The calculated cumulative LICR and HI values are provided
in Table 1, and copies of the completed DEQ Risk Calculator is provided in Appendix G.

As shown in Table 1, residential worst-case risk calculations using the sub-slab data indicates a
calculated cumulative LICR of 3.2 x 10-5 and a HI value of 0.11. The calculated cumulative LICR
and HI values are within the acceptable levels established by DEQ and EPA. The results of the
worst-case risk calculations indicate that the VIMS is effectively minimizing sub-slab
accumulation of compounds at concentrations that would pose potential vapor intrusion risk at
unacceptable levels for the residential building and parking garage.

3.4 Building Survey Activities

Prior to collecting indoor air samples, H&H completed a survey within the first turn of the multi-
family residential building and the parking garage elevator lobby to identify potential above-slab
sources of VOCs. At the time of sampling, some interior finishing work had been completed and
additional finishing work was ongoing, as explained further below in Section 3.5. H&H observed
use of heavy equipment outside of the building for ongoing construction-related purposes on-Site.
The heating, ventilation, and air conditioning (HVAC) system for the building was not operational
at the time of indoor air sampling.

H&H obtained available Safety Data Sheets (SDSs) for building materials used around the time of
the sampling event. The SDSs provided by the general contractor are provided in Appendix H.
VOCs were identified in the following building products:

 Xylenes and ethylbenzene were identified as product ingredients in the Sikaflex -2c NS EZ
Mix for both Parts A and B;
 Medium aliphatic hydrocarbon solvent was identified in the Sherwin Williams 950A
siliconized acrylic latex caulk;
13

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
 Heavy paraffinic oil was identified in the Sherwin Williams Painters Edge Plus latex paint;
and,
 Xylenes, ethylbenzene, and isopropylbenzene were identified in the Klean Strip Xylol
Xylene paint thinner;

Copies of the indoor air building survey form and the sampling forms completed by H&H sampling
personnel during the indoor air sampling event are included in Appendix E.

3.5 Indoor Air Sampling Methodology

On July 14, 2023 to July 15, 2023, H&H collected four indoor air samples (IAS-1 through IAS-4)
from within the first turnover portion of the multi-family residential and parking garage buildings.
As discussed in Section 3.6 below, there were unusual detections of TCE and other compounds in
one (1) indoor air (IAS-4), which were attributed to laboratory contamination associated with
improper cleaning of the Summa canister used to collect this sample. Due to the unusual TCE
detections in the July 2023 IAS-4 sample, DEQ Brownfields requested re-sampling of this
location. As such, one (1) additional indoor air sample (IAS-4) and a duplicate sample were
collected on September 2, 2023 to September 3, 2023. Indoor air samples were collected prior to
collection of sub-slab soil vapor samples to avoid potential cross-contamination associated with
temporarily opening and purging the sub-slab monitoring points. The IAS-3 indoor air sample
location was not included in the DEQ-approved VIMP, but was sampled as a conservative
approach since the Retrocoat in the elevator pit was not installed at the time of the pre-occupancy
sampling event.

Indoor air sampling was performed following VIMS installation activities and several weeks after
installation of the rooftop ventilators. As noted above, the building envelope was enclosed but
construction and finishing work were ongoing and the HVAC systems were not operational. The
installation of interior doors was not completed at the time of the indoor air sampling event.
Therefore, in order to isolate the locations in which samples were collected, each room was sealed
with plastic in place of the doors and windows, as needed. The locations of the indoor air samples
are shown on Sheet VM-3 in Appendix B.

In addition to the indoor air samples, an exterior background ambient air sample (IAS-BKG) was
collected at the time of each indoor air sampling event. The background sample was collected to
the southeast of the building and upwind as determined on the day of the sampling event based on
the prevailing wind direction.

The background and indoor air samples were collected using 6-liter stainless steel Summa sample
canisters connected to in-line flow controllers with a vacuum gauge. The July 2023 indoor air
samples IAS-1 through IAS-3 and background sample IAS-BKG were collected using
individually-certified Summa canisters, and IAS-4 was collected using a batch-certified Summa
canister. Note, the batch-certified Summa proposed for use as the background sample was
inadvertently used at the IAS-4 sample location. Based on discussions with the laboratory, there
is potential that residual concentrations remained in the batch-certified canister from the previous
sample event during which that canister was used (see Section 3.6 for further discussion). The
September 2023 indoor air sample IAS-4 and its duplicate were collected using individually-
certified Summa canisters, and the background sample was collected using a batch-certified
Summa canister.

The flow controllers for the background and indoor air samples were set by the laboratory to allow
collection of the samples over a 24-hour period. The sample intake point for each canister was
positioned approximately 5 ft above grade (typical breathing zone height). One duplicate indoor
air sample (IAS-DUP) was collected for quality assurance/quality control (QA/QC) purposes from
the IAS-2 parent location during the July 2023 sampling event. One duplicate indoor air sample
(IAS-DUP) was collected for QA/QC purposes from the IAS-4 parent location during the
September 2023 sampling event. Each duplicate sample was collected utilizing a laboratory-
supplied stainless-steel sampling “T” fitting which allows for the simultaneous collection of two
indoor air samples from a single air intake.

During the sampling activities, indoor/outdoor air pressure differential was measured for the
building near the start, middle, and end of the 24-hour sampling period using a manometer
sensitive to 0.001 inches of water. In addition, Site-specific weather conditions including exterior

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
wind speed, exterior wind direction, indoor and outdoor temperature, barometric pressure, and
precipitation were recorded near the start, middle, and end of the sampling period. Indoor air
sampling field forms completed by sampling personnel are included in Appendix E.

Prior to and after the indoor and background air samples were collected, vacuum in the canisters
was measured using a laboratory-supplied vacuum gauge and recorded by sampling personnel.
The starting vacuum was within 10% of the vacuum when the Summa canisters left the laboratory.
Vacuum within the sample canisters was not allowed to reach 0 inches of mercury; each sample
was collected after approximately 24 hours of run time.

The starting and ending vacuums in each canister were recorded by sampling personnel on the
sample chain of custody. The sample canisters were then labeled, packaged in a laboratory-
provided container, and shipped under standard chain of custody protocols to Con-Test for analysis
of a select list of VOCs by TO-15. The target analyte list was determined based on the VOCs
detected in the sub-slab soil vapor samples and is provided in Table 2.

3.6 July 2023 Indoor Air Sampling Results

The analytical results for the indoor air samples are summarized in Table 2, and the laboratory
analytical report with chain of custody record is provided in Appendix F. In Table 2, the indoor
air laboratory analytical results are compared to the DEQ Residential Vapor Intrusion Indoor Air
Screening Levels (IASLs) dated July 2023. In addition, a comparison of co-located sub-slab soil
gas and indoor air concentrations for the July 2023 sampling event is provided in Table 3.

The indoor air sample analytical results indicate that several compounds were detected at
concentrations above laboratory MDLs in each sample. The following compounds were detected
above the Residential IASLs in select indoor air sample locations:

 Benzene was detected in IAS-1, IAS-2/IAS-DUP, and IAS-4 (ranging from 0.40 µg/m3 to
1.2 µg/m3) at concentrations exceeding the Residential IASL of 0.36 µg/m3.

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
 Chloroform was detected above the Residential IASL of 0.12 µg/m3 in IAS-2 (0.20 µg/m3)
and IAS-4 (0.47 µg/m3); however, chloroform was not detected above the laboratory MDL
in the duplicate sample (IAS-DUP) collected at the IAS-2 sample location.

 Ethylbenzene was detected in IAS-1, IAS-3, and IAS-4 at concentrations ranging from 1.7
µg/m3 to 2.3 µg/m3, which exceed the Residential IASL of 1.1 µg/m3.

 2-Hexanone was detected in IAS-4 at a concentration of 16 µg/m3, above the Residential
IASL of 3.6 µg/m3.

 Naphthalene was detected in each indoor air sample (up to 0.95 µg/m3 in IAS-4) at
concentrations above the Residential IASL of 0.083 µg/m3.

 Trichloroethene (TCE) was detected in the indoor air sample IAS-4 at a concentration of
1.9 µg/m3, which exceeds the Residential IASL of 0.42 µg/m3.

No other compounds were detected above the Residential IASLs in the indoor air samples
collected in July 2023.

The background ambient air sample IAS-BKG was collected upwind of the multi-family
residential building to evaluate ambient air conditions. Several compounds were detected in the
background sample at concentrations exceeding the laboratory MDLs, and benzene and
naphthalene were detected at concentrations exceeding the IASLs. Benzene was detected at a
concentration of 0.43 µg/m3 and naphthalene was detected at a concentration of 0.30 µg/m3. The
detected benzene and naphthalene concentrations are consistent with the concentrations detected
in the indoor air samples. Additionally, although 2-hexanone and ethylbenzene were not detected
above the Residential IASLs in the background sample, these compounds were detected above the
laboratory MDLs indicating above-ground sources.

As noted during the building survey, heavy machinery was operating at the Site as part of ongoing
construction activities which could be a potential above-grade source of petroleum compounds
including benzene, naphthalene, and ethylbenzene in indoor air. Additionally, xylenes,
ethylbenzene, paraffin oil, and aromatic hydrocarbons were identified in products being used
17

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
inside the building. Based on the ongoing construction activities, compounds identified in
background air sample detections, and compounds identified in products used in the building, the
VOC concentrations detected in the indoor air samples at locations IAS-1 through IAS-3 are likely
associated with above-ground sources and not sub-slab vapor intrusion.

As noted above, the batch-certified Summa canister was inadvertently used at the IAS-4 sample
location. Review of analytical results for IAS-4 indicate concentrations of compounds, including
2-hexanone and TCE, that are inconsistent with the other indoor air samples collected at the Site.
Additionally, analytical results from monitoring point MP-3, located in the stairwell adjacent to
the residential unit in which IAS-4 was collected, indicated 2-hexanone was not detected above
the laboratory MDL and TCE was detected at an estimated (J-flag) concentration of 0.47 J µg/m3.
Based on the anomalous detections in IAS-4, H&H contacted Con-Test to inquire about the results
of the batch certification as well as the analytical results from the last sampling event during which
that specific Summa canister was used. Con-Test indicated that although the batch certification
results passed the cleaning standards, the analytical results for the last sample event at which that
Summa canister was used indicated a 1200x dilution was required on the sample due to the TCE
concentration. The elevated dilution requirement due to the TCE concentration indicates that an
elevated TCE concentration was detected during that event, and Con-Test indicated that there is a
potential that residual TCE remained after cleaning. According to Con-Test, the last event was
only a select TO-15 list, so 2-hexanone was not reported; however, it is likely that the can was
incompletely cleaned and contributed to the indoor air concentrations in IAS-4. The elevated
detection of TCE is considered carryover from the laboratory, and the detected concentrations in
IAS-4 are not considered representative of Site conditions. The IAS-4 location was re-sampled in
September 2023, and TCE was not detected in the sample as discussed below.

3.7 September 2023 Indoor Air Sampling Results

The analytical results for the September 2023 re-sampling of the IAS-4 location are included in
Table 2, and the laboratory analytical report with chain of custody record is provided in Appendix
F. In Table 2, the indoor air laboratory analytical results are compared to the DEQ Residential
Vapor Intrusion IASLs dated July 2023. In addition, a comparison of co-located sub-slab soil gas

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
and indoor air concentrations for the July 2023 sampling event and the September 2023 resampling
event is provided in Table 3.

The following compounds were detected above the Residential IASLs in the September 2023 IAS-
4 and/or duplicate indoor air samples:

 Benzene (up to1.5 µg/m3) was detected at concentrations exceeding the Residential IASL
of 0.36 µg/m3.

 Chloroform (up to 0.22 µg/m3) was detected above the Residential IASL of 0.12 µg/m3.

 1,2-Dibromoethane or EDB (up to 0.15 J µg/m3) was detected above the Residential IASL
of 0.0047 µg/m3.

 Ethylbenzene (up to 9.2 µg/m3) was detected above the Residential IASL of 1.1 µg/m3.

 Naphthalene (up to 0.62 µg/m3) was detected at concentrations above the Residential IASL
of 0.083 µg/m3.

No other compounds were detected above the Residential IASLs in the indoor air samples
collected in September 2023. Notably, TCE not detected above laboratory MDLs in the September
2023 IAS-4 or duplicate samples.

The background ambient air sample IAS-BKG was collected upwind of the multi-family
residential building to evaluate ambient air conditions. Several compounds were detected in the
background sample at concentrations exceeding the laboratory MDLs, and benzene, carbon
tetrachloride, chloroform, EDB, and naphthalene were detected at concentrations exceeding the
IASLs. The detected concentrations of benzene, carbon tetrachloride, chloroform, EDB, and
naphthalene in the outdoor, background air sample are similar to the concentrations detected in the
indoor air samples. Additionally, ethylbenzene and aromatic hydrocarbons were identified in
products being used inside the building. Based on the ongoing construction activities, compounds
19

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
identified in the background air sample, and compounds identified in products used in the building,
the VOC concentrations detected in the September 2023 indoor air samples appear to be associated
with above-ground sources and are not associated with sub-slab vapor intrusion.

3.8 Indoor Air Vapor Intrusion Evaluation

The DEQ IASLs are conservative and based on a TCR for potential carcinogenic risks of 1 x 10-6
and a THQ of 0.2 for potential non-carcinogenic risks and only apply to indoor air contaminants
from structural vapor intrusion. As noted previously, the DEQ and EPA acceptable risk level for
potential carcinogenic risks is a cumulative LICR of 1 x 10-4 or less and the acceptable level for
non-carcinogenic risks is a HI of 1.0 or less.

H&H utilized the DEQ Risk Calculator (July 2023) to evaluate risks associated with the detected
indoor air concentrations. Risk calculations were completed assuming a residential use scenario
for each sample using the concentrations of any compound detected at each indoor air sample
location. Note, although H&H considers the petroleum compounds to be attributable to above-
ground sources, the concentrations were used in the risk calculations as a conservative measure.
Although the July 2023 IAS-4 analytical results are considered carryover from the laboratory,
H&H ran a risk calculator for comparison. Additionally, H&H ran a risk calculator for the
September 2023 IAS-4 analytical results for comparison. The calculated cumulative LICR and HI
values for each sample are summarized below and included in Table 2.

Sample Location
Calculated
Cumulative
LICR
Calculated
Cumulative HI
Calculated LICR or HI
Exceeds Acceptable
Risk Levels?
IAS-1 7.8 x 10-6 0.46 No
IAS-2/IAS-DUP 1.0 x 10-5 0.42 No
IAS-3 9.2 x 10-6 0.39 No
IAS-4 (July 2023) 2.5 x 10-5 2.5 Yes
IAS-4/IAS-DUP
(September 2023) 5.5 x 10-5 1.1 Yes

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/trammell crow residential - tcr/tcr-001
yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
The calculated risks for a residential scenario for the indoor air samples indicate acceptable
cumulative LICR HI values for sample locations IAS-1 through IAS-3. The calculated LICR for
the July 2023 indoor air sample IAS-4 is below acceptable risk levels; however, the HI exceeds
the acceptable level of 1.0. As noted above, the July 2023 IAS-4 canister was impacted by
laboratory carryover. The calculated HI values highlight the discrepancy between IAS-1 through
IAS-3, which are representative of building conditions, and IAS-4 which is not considered
representative.

The calculated LICR for the September 2023 indoor air sample IAS-4 is below acceptable risk
levels; however, the HI slightly exceeds the acceptable level of 1.0. The main contributors to the
HI exceedance include xylenes and naphthalene. As noted above, these compounds were detected
in the background sample collected during the September 2023 sampling event and/or are
compounds present in construction materials identified during the survey activities. Specifically,
the SDS sheets list petroleum-based products such as cleaner/thinners (Klean Strip Xylol Xylene)
which likely contributed to the detected concentrations of petroleum compounds in the indoor air
samples. Safety data sheets for materials used during construction are included in Appendix H.
Based on the ongoing construction activities, compounds identified in background air sample
detections, and compounds identified in products used in the building, the VOC concentrations
detected in the indoor air samples are likely associated with above-ground sources and not sub-
slab vapor intrusion.

4.0 Summary and Conclusions

Installation of the VIMS has been completed for the northeastern portion of the multi-family
residential building and the parking deck, identified as the first turn of the development, at the
Yandle-Witherspoon Supply, Inc. Brownfields property (Brownfields Project No. 24010-20-060).
Results of installation inspections, influence testing, and effectiveness sampling activities indicate
that the VIMS has been successfully installed in accordance with the DEQ-approved VIMP.

During construction of the Site building, H&H conducted VIMS installation inspections to verify
that the systems were installed as designed and completed post-installation VIMS testing activities
to evaluate the effectiveness of the VIMS. A brief summary of the VIMS installation and post-
installation effectiveness assessment activities is provided below.

VIMS Installation and Influence Testing
VIMS installation has been completed for the first turnover at the northeastern portion of the multi-
family residential building and the elevator and elevator lobby in the parking garage. The VIMS
includes a gravel layer, vapor barrier, sub-slab horizontal collection mat, and vertical extraction
piping to the roof connected to rooftop ventilators. In addition, the parking garage elevator
includes RetroCoat installation along the elevator pit interior. During installation of the VIMS,
H&H personnel, under the direction of a NC licensed Professional Engineer, conducted
inspections during each stage of installation. As documented during the inspections and in the Site
photographs, the VIMS was installed in general accordance with the DEQ-approved VIMP, with
the exception of the DEQ and design engineer approved modifications noted herein.

Following installation of the VIMS sub-slab piping network and riser piping, H&H completed
vacuum influence pilot testing to evaluate vacuum communication beneath the slab. Final vacuum
measurements collected during the pilot testing activities indicate that vacuum communication
beneath the slab of the first turnover portion of the building was achieved with acceptable
differential pressure levels.

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx
VIMS Effectiveness Testing – Sub-Slab Soil Gas
Sub-slab soil gas analytical results for the first turn indicate that carbon tetrachloride, chloroform,
and 1,2-dibromoethane were detected at concentrations exceeding the DEQ Residential Vapor
Intrusion SGSLs in select samples. No other compounds were detected above the Residential
SGSLs. Results of the hypothetical worst-case risk calculations indicate acceptable risk levels for
a residential exposure scenario. Based on the sub-slab soil vapor data and the DEQ Risk Calculator
results, the detected sub-slab vapor concentrations at the Site do not pose an unacceptable vapor
intrusion risk.

VIMS Effectiveness Testing – Indoor Air
In accordance with the DEQ-approved VIMP, indoor air samples were collected from select first
floor locations in the first turn of the multi-family residential building and parking garage elevator
lobby. The analytical results indicate that several VOCs were detected in the samples at
concentrations above the laboratory MDLs. Benzene, chloroform, ethylbenzene, and naphthalene
were detected above the DEQ Residential Vapor Intrusion IASLs. The background ambient air
sample results indicate that benzene and naphthalene were detected at concentrations exceeding
the Residential IASLs, and several VOCs, including ethylbenzene, were identified in products
used in the building. Based on the background ambient air detections, identification of compounds
in the building materials, and sub-slab soil gas concentrations that are not indicative of vapor
intrusion, the detected indoor air concentrations are likely attributable to an above-grade source.

TCE and 2-hexanone were detected in the July 2023 indoor air sample IAS-4 above the Residential
IASLs; however, the indoor air concentrations were inconsistent with the other indoor air samples.
Furthermore, 2-hexanone was not detected above the laboratory MDL and TCE was detected at an
estimated, trace concentration in the adjacent sub-slab soil gas sample. A batch-certified canister
was inadvertently used to collect the July 2023 IAS-4 indoor air sample. Con-Test indicated that
there was potential laboratory carryover due to the TCE concentration from the previous event in
which that canister was used, and the concentrations detected in IAS-4 are not considered
representative of building conditions. Results of September 2023 re-sampling further confirmed
that the concentration of TCE detected during the July 2023 sampling event was laboratory
carryover.

yandle witherspoon/vims/installation report_1st turnover/24010-vims install rpt - alexan optimist2.docx

The risk calculations completed for each indoor air sample location IAS-1 through IAS-3 indicate
that compound concentrations detected in the indoor air do not pose vapor intrusion risks at
unacceptable levels assuming a residential use scenario. The September 2023 IAS-4 indoor air
sample indicates an HI slightly above the acceptable level; however, the primary risk drivers are
petroleum-related compounds attributable to construction materials used on-Site and are not
attributable to vapor intrusion.

Summary
Based on the VIMS installation inspections, influence testing, post-installation sub-slab soil vapor
sampling results, and indoor air sampling results, the VIMS is effectively mitigating potential
vapor intrusion risks within the first turn of the multi-family residential building and elevator and
elevator lobby in the parking garage. In accordance with the DEQ-approved VIMP, post-
occupancy sub-slab soil vapor sampling will be completed approximately 6 months following the
pre-occupancy event and on a semi-annual basis for future events. The first post-occupancy
sampling event will occur in January 2024. If semi-annual sampling results indicate consistent or
decreasing concentrations within acceptable risk levels, a request to modify or terminate sampling
will be submitted for DEQ approval. After each post-construction sampling event, a brief report
will be submitted to DEQ to document the sampling activities and results.

Engineer’s Certification
According to the DWM Vapor Intrusion Guidance: “Risk-based screening is used to identify sites
or buildings likely to pose a health concern, to identify buildings that may warrant immediate
action, to help focus site-specific investigation activities or to provide support for building
mitigation and other risk management options including remediation.” In addition, the DEQ-
approved VIMP was prepared to satisfy the standard vapor intrusion mitigation provisions
included in the Brownfields Agreement. Per the North Carolina Brownfields Property Reuse Act
130A-310.32, a prospective developer, with the assistance of H&H for this project, is to provide
DEQ with “information necessary to demonstrate that as a result of the implementation of the
brownfields agreement, the brownfields property will be suitable for the uses specified in the
agreement while fully protecting public health and the environment instead of being remediated to

unrestricted use standards.” It is in the context of these risk-based concepts that the H&H
professional engineer makes the following statement:

The Vapor Intrusion Mitigation System (VIMS) detailed herein is designed to mitigate intrusion
of subsurface vapors into the subject buildings from known Brownfields Property contaminants in
a manner that is in accordance with the most recent and applicable guidelines including, but not
limited to, DWM Vapor Intrusion Guidance, Interstate Technology & Regulatory Council (ITRC)
guidance, and American National Standards Institute (ANSI)/American Association of Radon
Scientists and Technologists (AARST) standards. The sealing professional engineer below is
satisfied that the design and its installation are fully protective of public health from known

1.THESE AS-BUILT DRAWINGS ARE INTENDED TO DOCUMENT THE VIMS COMPONENT INSTALLATION ONLY AND IS NOT INTENDED TO DOCUMENT CONSTRUCTION OF STRUCTURAL COMPONENTS
NOT RELATED TO THE VIMS.
2.VIMS VAPOR LINER USED WAS MONOSHIELD™ MANUFACTURED BY LAND SCIENCE. THE VAPOR LINER WAS INSTALLED BY S&H WATERPROOFING, A LAND SCIENCE CERTIFIED INSTALLER, AS
SPECIFIED HEREIN AND PER MANUFACTURER INSTALLATION INSTRUCTIONS TO CREATE A CONTINUOUS LINER BELOW GROUND FLOOR SLABS. MONOSHIELD IS A VAPOR BARRIER SYSTEM WHICH
CONSISTS OF MONOBASE, A COMPOSITE GEOMEMBRANE, THAT IS SEALED TOGETHER AT SEAMS USING NITRA-CORE, A SPRAY APPLIED ASPHALT LATEX, APPLIED AT A MINIMUM THICKNESS OF 60
MIL. A BASE COURSE CONSISTING OF CLEAN #57 WAS INSTALLED BENEATH THE MONOSHIELD VAPOR LINER. THE BASE COURSE LAYER IS A MINIMUM OF 4 INCHES THICK AND WAS INSTALLED
WITH A MINIMUM 1-INCH LAYER BELOW THE TERRAVENT, WHERE PRESENT. HORIZONTAL COLLECTION PIPE CONSISTS OF TERRAVENT™ (1" BY 12") WITH 3" OR 4" SCH 40 PVC AT SUB-GRADE
FOUNDATIONS.
3.ALL PENETRATIONS WERE SEALED ACCORDING TO LANDSCIENCE MANUFACTURER INSTALLATION INSTRUCTIONS AS FOUND IN THE MANUFACTURER INSTALLATION GUIDELINES. SMALL PUNCTURE
HOLES WERE SEALED WITH THE NITRA-CORE™ AND LARGER HOLES, TEARS, OR DAMAGE WERE REPAIRED USING A PATCH THAT OVERLAPPED THE DAMAGED AREA AND THEN SPRAYED WITH
NITRASEAL ALONG THE SEAMS. UTILITY PENETRATSION WERE SEALED WITH 30 MIL OF NITRA-CORE, THEN A PIECE OF REINFORCEMENT FABRIC WAS WRAPPED AROUND THE NITRA-CORE AT THE
BASE OF THE PENETRATION. AN ADDITIONAL 30 MIL OF NITRA-CORE WAS APPLIED AND THE REINFORCEMENT FABRIC AND NITRA-CORE LAYERS WERE CABLE TIED TO CREATE A SEAL.
MEASUREMENTS WERE COLLECTED TO DOCUMENT THE NITRA-CORE THICKNESS AT SEAMS DURING APPLICATION AND SMOKE TESTING WAS COMPLETED IN ACCORDANCE WITH THE
MANUFACTURER RECOMMENDATIONS.
4.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS MINIMIZED THE USE OF TEMPORARY FORM BOARDS THAT PENETRATED THE VAPOR LINER. IN CASES WHERE TEMPORARY FORM BOARDS
WERE USED, THE SIZE AND NUMBER OF PENETRATIONS THROUGH THE VAPOR LINER WAS LIMITED AND SOLID METAL STAKES WERE USED. AS FORM BOARDS WERE REMOVED, THE CERTIFIED
INSTALLER SEALED ALL PENETRATIONS IN ACCORDANCE WITH VAPOR LINER MANUFACTURER INSTALLATION INSTRUCTIONS.

PART 3 – EXECUTION
3.1 AUXILIARYMATERIALS
A.Examine substrates, areas, and conditions under which vapor intrusion barrier will be applied, with installer
present, for compliance with requirements. Do not proceed with installation until unsatisfactory conditions
have been corrected.
3.2 SUBGRADESURFACEPREPARATION
A.Verify substrate is prepared according to manufacturer’s recommendations. On a horizontal surface, the substrate
should be free from material that can potentially puncture the vapor intrusion barrier. Additional protection or
cushion layers might be required if the earth or gravel substrate contains too many jagged points and edges that
could puncture one or more of the system components. Contact manufacturer to confirm substrate is within
manufactures recommendations.
B.MonoShield™ System can accommodate a wide range of substrates, including but not limited to compacted earth,
sand, aggregate, and mud slabs.
1.Compacted Earth: Remove pieces of debris, gravel and/or any other material that can potentially puncture
the MonoBase prior to application.
2.Sand: A sand subgrade requires no additional preparation, provided any material that can potentially
puncture MonoBase not present.
3.Aggregate:Contact the manufacturer to ensure the aggregate layer will not be detrimental to the
MonoBase. The gravel layer must be compacted and rolled flat.Ideally a ¼” minus gravel layer with
rounded edges should be specified; however MonoBasecan accommodate a wide variety of different
substrates. Contact Land Science if there are questions regarding the compatibility of MonoBase and theutilizedsubstrate. Exercise caution when specifying pea gravel under the membrane, if not compacted
properly, pea gravel can become an unstablesubstrate. NOTE: Angular substrates will likely require the
use of a 4 oz. geotextile cushion layer, contact LandSciencefor additional information.
4.Mudslabs: The use of a mubslab under the MonoBaseis acceptable, contact Land Science for job specificrequirements.
C.Mask off adjoining surface not receiving the vapor intrusion barrier system to prevent the spillage or over spray
affecting other construction.
D.Earth, sand or gravel subgrades should be prepared and compacted to local buildingcode requirements.
3.3 PREPARATIONS AND TREATMENT OF TERMINATIONS
A.Prepare thesubstratesurface in accordance withSection 3.3 of this document. Concretesurfaces that are not a light
trowel, light broom or equivalent finish, will need to be repaired.
B.Terminations on horizontal and vertical surfaces should extend 6” onto the termination surface. Job specific conditions
may prevent a 6” termination. In these conditions, contact manufacturer for recommendations.
C.Apply 60 mils of Nitra-Core to the terminating surface and then embed the MonoBase by pressing it firmly into the Nitra-
Core layer. Next, apply 30 mils of Nitra-Core spray applied on MonoBase over the edge of the termination. For further
clarification, refer to the termination detail provided by manufacturer.
D.Thestatedterminationprocess is appropriate forterminatingthemembrane onto exteriorfootings, pilecaps, interior
footings and grade beams. When terminating the membrane to stem walls or vertical surfaces the same process
shouldbe used.
3.4 PREPARATIONS ANDTREATMENT OF PENETRATIONS
A.All pipe penetrations should be securely in place prior to the installation of the MonoBase. Any loose penetrations
02 56 19.13-5
should be secured prior to MonoBase, as loose penetrations could potentially exert pressure on the membrane and
damage the membrane after installation.
B.To properly seal around penetrations, cut a piece of the MonoBasethat will extend 6” beyond the outside perimeter of
the penetration. Cut a hole in the MonoBase just big enough to slide over the penetration, ensuring the MonoBase fits
snug against the penetration, this can be done by cutting an “X” no larger than the inside diameter of the penetration.
Thereshould not be a gap larger than a 1/8” between the MonoBase andthe penetration. Other methods can also be
utilized, provided, there is not a gap larger than 1/8” between the MonoBase and the penetration.
C.Seal the MonoBase using Nitra-Core spray applied or Nitra-Core Detail to the underlying cut piece of MonoBase.
D.Apply one coat of Nitra-Core spray or Nitra-Core Detail to the MonoBase and around the penetration at a thickness
of 30 mils. Penetrations should be treated in a 6-inch radius around penetration and 3 inches onto penetrating
object.
E.Embed a Detail Fabric strip after the first application of the Nitra-Core spray applied or Nitra-Core Detail material
and then apply a second 30 mil coat over the embedded joint reinforcing strip ensuring its complete saturation of
the embedded strip and tight seal around the penetration.
F.A cable tie should then be placed around the finished penetration. The cable tie should be snug, but not overly
tight so as to slice into the finished seal.
OPTION: A final application of Nitra-Core spray may be used to provide a finishing seal after the protective layer has
been installed.
NOTE: Metal or other slick penetration surfaces may require treatment in order to achieve proper adhesion. For plastic
pipes, sand paper may be used to achieve a profile, an emery cloth is more appropriate for metal surfaces. An emery cloth
should also be used to remove any rust on metal surfaces.
3.5 MONOBASE INSTALLATION
A.Install the MonoBase over substrate material in one direction with six-inch overlaps.
B.Secure the MonoBase layer by applying 60 mils of Nitra-Core tween the 6” overlapped sheets.
C.Visually verify there are no gaps/fish-mouths in seams.
D.For best results, install an equal amount of MonoBaseand Nitra-Core in one day. Leaving the MonoBase
unsprayed overnight might allow excess moisture to collect on the MonoBase. If excess moisture collects, it
needs to be removed.
NOTE: In windy conditions it might be necessary to encapsulate the seam by spraying the Nitra-Core layer over the
completed MonoBaseseams.
3.6 NITRA-COREAPPLICATION
A.Set up spray equipment according to manufacturer’s instructions.
B.Mix and prepare materials according to manufacturer’s instructions.
C.The two catalyst nozzles (8001)should be adjusted tocross at about 18" from the end of the wand. This apex of
catalyst and emulsionspray should then be less than 24" but greater than 12” from the desiredsurfacewhenspraying.
When properly sprayed the fan pattern of the catalyst should range between 65° and 80°.
D.Adjust the amount of catalyst used based on the ambient air temperature and surfacetemperature ofthesubstrate
receiving the membrane. In hot weather use less catalyst as hot conditions will quickly “break” the emulsion andfacilitate the curing of the membrane. Incoldconditions and on vertical surfaces usemore catalyst to “break”the
emulsion quicker to expeditecuringand set up time in cold conditions.
E.To spray Nitra-Core layer, pull the trigger on the gun. A 42° fan pattern should form when properly sprayed. Apply one
spray coat of Nitra-Core to obtain a seamless membrane free from pinholes or shadows, with an average dry filmthickness of 60 mils (1.52 mm).
F.Apply the Nitra-Core layer in a spray pattern that is perpendicular to the application surface. The concern when spraying
at an angle is that an area might be missed. Using a perpendicular spray pattern will limit voids and thin spots and will
also create a uniformandconsistentmembrane.
G.The seamswill generally cure in 24 to 48 hours. As a rule, when temperature decreases or humidity increases, the
curing of the membrane will be prolonged. The membrane does not need to be fully cured prior to smoke test.
H.Do not penetrate membrane after it has been installed. If membrane is penetrated after the membrane is
installed, it is the responsibility of the general contractor to notify the certified installer to make repairs.
I.Conducting smoke tests on the barrier is recommended with general emphasis towards the seams,
02 56 19.13-6
penetrations, and perimeter terminations. Land Science recommends conducting smoke tests every 5,000-
10,000 square feet or a minimum of two per building structure (if less than 5,000 square feet in size). The
square footage for testing can be increased upon successful smoke tests conducted initially at a 5,000 square
foot area.
NOTE: Care should be taken to not trap moisture between the layers of the membrane. Trapping moisture may
occur from applying a second coat prior to the membrane curing. Repairs and detailing may be done over the Nitra-
Core layer when not fully cured.
3.7 PROTECTION LAYER INSTALLATION (optional)
A.Install protective course overMonoBase before starting subsequent construction operations.
B.Sweep off any water that has collected on the surface of the MonoBase prior to the placement of the protective course.
C.Overlap and seam the protective layer in the same manner as the MonoBase.
3.8 QUALITYASSURANCE
A.The MonoShield
™ system must be installed by a trained and certified installer approved by Land Science.
B.For projects that will require a material or labor material warranty, Land Science will require a manufacturer’s
representative or certified 3
rd party inspector to inspect and verify that the membrane has been installed per the
manufacturer’srecommendations.
The certified installer is responsible for contacting the inspector for inspection. Prior to application of the
membrane, a notice period for inspection should be agreed upon between the applicator and inspector.
C.Smoke Testing is highly recommended and is the ideal way to test the seal created around penetrations and
terminations.Smoke Testing is conducted by pumping non-toxic smoke underneath the MonoShield™ system and
then repairing the areas where smoke appears. Refer to smoke testing protocol provided by Land Science. For
projects that will require an extended material warranty, Land Science will require a smoke test.
D.Visual inspections prior to placement of concrete, but after the installation of concrete reinforcing, is recommended
to identify any punctures that may have occurred during the installation of rebar, post tension cables, etc.
Punctures in the MonoShield
™ system should be easy to identify due to the color contrasting layers of thesystem.

Chemical Resistance

Vapor Intrusion Coating System for Existing Structures
Product Description
The Retro-Coat™ (patent pending) Vapor Intrusion
Coating System is a complete product line that consists of
chemically resistant materials to properly protect existing
structures from the threat of contaminant vapor intrusion
without the need for additional concrete protection.
Developed by the R&D team of Land Science
Technologies™, the Retro-Coat system has been subjected
to rigorous testing procedures to prove its ability to combat
the most aggressive chemical vapors. The main component
of the Retro-Coat system is the Retro-Coat coating which is
a two part, odorless, no VOC, 100% solids coating.

Retro-Coat finishes to a high gloss, easy-to-clean surface
that is impervious to vapor and moisture transmission.
Available in a variety of colors, Retro-Coat can be applied
on damp as well as dry concrete, concrete masonry units,
tile, brick and metal. For enhanced slip resistance, a
suitable aggregate can be added. In addition, other
additives or materials can be utilized to achieve a desired
performance or aesthetic look.

Typical Application
Retro-Coat is suitable as a barrier to block contaminated
vapors from entering existing structures. Particular uses
include coating the horizontal surfaces of existing structures
where contamination under, or adjacent to, a structure can
potentially migrate inside the structure and create a vapor
encroachment condition. This condition is most commonly
found when the existing structure was operated as a dry
cleaner, gas station, manufacturing facility or located in
close proximity to any structure where carcinogenic
chemicals were utilized.
A typical application consists of a minimum 20 mil thick
system; consisting of two 10 mil coats of Retro-Coat at 160
SF/gallon per coat and is recommended along with a 6 mil
coat of Retro-Coat PRIMER. The typical 20 mil application
can withstand forklift traffic, other machinery and even act
as secondary containment. However, if Retro-Coat may be
exposed to more harsh conditions over a longer period of
time, thicker applications ranging from 60 mil to ¼ -inch may
be more suitable.
In either application, Retro-Coat is a traffic bearing surface
and does not need a protective course placed over it.

Retro-Coat Advantages

• Our R&D team developed all of the
Retro-Coat system components
specifically for vapor intrusion
protection in existing structures

• Retro-Coat is resistant to both TCE and
PCE, the vast majority of coatings
cringe at such aggressive chemicals

• Retro-Coat is a wearing surface,
meaning no additional concrete
protection is necessary

• No odor and fast cure time reduce
building downtime

• Carpet, tile, linoleum or other floor
coverings can be applied directly over
Retro-Coat, if desired

• Eliminates the need to remove the
existing slab and when combined with
in-situ treatment, lowers overall
remediation cost

• Retro-Coat can increase the
performance of an existing active sub-
slab depressurization system

• Retro-Coat can aid in the retiring of
existing active systems

• Available and installed by Land
Science Technologies certified
contractors

Installation
Particular care must be taken to follow those instructions precisely to assure proper installation. These instructions
pertain to a standard 20 mil application; please contact us if the desired application is different.

1. New concrete should be allowed to cure a minimum of 28 days and/or be checked with a rubber mat or plastic sheet to
ensure adequate curing time has occurred.
2. All surfaces to be covered should be power washed, shot blasted, acid etched, scarified or sanded to present a clean,
sound substrate to which to bond to. The prepared surface should have a ph of 7.
3. Any bugholes and cracks wider than 1/8” should be filled with Retro-Coat PREP and allowed to dry before coating. More
severely damaged concrete or other special conditions will require the proper Retro-Coat product.
4. When installing the standard 20 mil application of Retro-Coat, apply a 6 mil coat of Retro-Coat PRIMER and
allow to dry prior to applying the initial coat of Retro-Coat. Priming may not be necessary when Retro-Coat
is applied to a thickness greater than 20 mils. On new concrete or old concrete with an open porosity and on
wood surfaces apply Retro-Coat PRIMER and allow to dry.
5. The two Retro-Coat ingredients should be mixed in the prescribed ratios, using a low speed “jiffy-style” mixer,
(maximum 750 rpm). Mix Part A for about 1 minute then, add Part B and mix until uniform in color and consistency (at
least one additional minute.)
6. Do not mix less than the prescribed amount of any ingredient or add any solvent to the mix.
7. Apply the mixed Retro-Coat material with a short nap roller, a squeegee or a brush. Apply
approximately 160 SF per gallon per coat to achieve 10 mils of coating.
8. Apply a second coat while the first coat is still tacky if using spike shoes or dry enough to walk on, but before 7
hours at 75oF. If the first coat has set and is no longer tacky then the first coat should be sanded before
recoating.
9. A suitable aggregate may be broadcast onto the surface after backrolling to provide more anti-slip profile to the finished
surface. It is advisable to test various types and sizes of aggregate to achieve the desired finished profile.

Product Specification
The specified area shall receive an application of Retro-Coat as manufactured by Land Science Technologies, San
Clemente, California. The material shall be installed by precisely following the manufacturer’s published
recommendations pertaining to surface preparation, mixing and application. The material shall be a low odor, two
part, solvent free 100% solids, high gloss flexibilized system with good resilience to resist thermal and
mechanical shock. It should be able to be roller applied at a minimum of 10 mils thickness per coat on vertical
surfaces without sagging (at ambient conditions). The system must adhere to damp as well as dry concrete, wood,
metal tile, terrazzo and sound existing epoxy and urethane coatings. It shall have tensile elongation of at least 6.0%
when tested under ASTM-638. Its bond strength to quarry tile shall exceed 1000 psi when tested with an
Elcometer pull test. Its hardness shall not exceed 83, as measured on the Shore D scale. The system shall be
unaffected by oils and greases and shall withstand chemical attack for at least 72 hours against 98% sulfuric,
50% hydrofluoric acid, glacial acetic acid and acrylonitrile.

Part 2 – Application
2.1 Surface Preparation

A. All existing surfaces that will be covered with the systems specified herein should be mechanically ground, shot
blasted or sand blasted to yield a minimum 60 grit surface texture. All loosely adhered coatings will be removed. Any grease and other contaminants found on the concrete must also be removed.

B. All open cracks 1/2” and greater should be v-notched to a 3/4” width by 1/2” depth and cleaned of any debris.
Such cracks should be filled with Retro-Coat Gel and struck off flush with the surrounding surface.

C. Cut back and/or remove any expansion joint backing or filler strips to a minimum of 1 ½” deep. Insert
disposable filler in the joints to prevent filling with the overlayment materials and to allow for accurate location of
final saw cuts in the overlayment.

2.2 Material Application

A. Retro-Coat CAULK

1. Apply Retro-Coat CAULK around the base of all pipe penetrations making sure to fill any gap between the
penetration and concrete slab

2. Apply Retro-Coat CAULK to the joint created between horizontal and vertical
transitions. The caulking material should be applied and pressed into the joint filling
any gaps that might be present.

B. Retro-Coat PRIMER

1. Apply Retro-Coat PRIMER to all areas at a thickness of 6 mil and allow to dry tack free. In areas where
the concrete surface is in need of slight repair or needs to be leveled, a slurry form of Retro-Coat PRIMER
called Retro-Coat PRIMER-S can be applied with a flat squeegee. Retro-Coat PRIMER-S is self priming
and does not need to be primed again.

C. Retro-Coat

1. Mix Retro-Coat, Part A with a low-speed (<750 rpm) jiffy-style mixer for about 30 seconds, or until uniform
in color, then mix in Retro-Coat Coating, Part B for another 30-60 seconds.

2. Dump contents onto floor in a ribbon pattern, squeegee, and then back roll at a coverage rate of 160
SF/gallon to achieve a film thickness of 10 mils.
3. Apply second coat 10 mil coat to achieve a total thickness of 20 mils. Repeat as necessary to achieve
specified thickness.

4. If a flooring material will be placed over Retro-Coat after it is applied, or appearance is not a priority, (1) 20
mil coat can be applied.
2.3 Protection of Finished Work
A. Prohibit foot traffic on floor for 24 hours after laying (at 70ºF). At 50ºF,this time should be extended to 48 hours.

B. Rinse off any chemicals that may come in contact within 7 days of installation with the freshly laid floor
immediately.

Part 3 – Quality Control

3.1 Warranty

A. Installer shall provide a one year warranty against delamination, chemical attack and normal wear and tear.

B. Manufacturer will provide a one year material warranty.
3.2 Quality Control

A. Installer shall use a notched squeegee to apply Retro-Coat to the specified mil thickness and calculations shall
be done to determine if the correct amount of material has been applied. Retro-Coat contains 100% solids at the time of application; therefore no material shrinkage will occur during the curing process. One gallon will
cover 80 square feet.

B. A wet mil film gauge can be used to spot check the Retro-Coat thickness to make certain the minimum 20 mil
thickness has been applied, though some discretion should be used because high points or low points on the
underlying surface can adversely affect the thickness measurements.
3.3 Floor Care

A. The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner,
preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry.
Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor.

B. Additional steps can also be taken to prolong the look and life of a seamless floor:

1. Protect the floor during transference of heavy equipment

2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well as
keeping the metal forks lifted

3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt,
on the coating

4. Eliminate all metal wheels

5. Change over to light-colored polyurethane wheels

6. Do not slide heavy metal totes, drums or bins across the floor

7. Immediately hose down chemical spills, especially on newly laid floors.

4.0 FIRST-AID MEASURES 4.1 Description of necessary first-aid measures:
Eye Contact: Immediately flush eyes with large amounts of water or normal saline for at least 30 minutes. Hold eyelids apart while flushing to rinse entire surface of eye and lids with water. Then remove contact lenses, if easily removable, and continue eye irrigation for not less than 15 minutes. Get medical attention if irritation develops. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Call a physician if irritation persists. Wash clothing before reuse. Inhalation: Remove victim to fresh air if effects occur. If not breathing, give artificial respiration. Get immediate medical attention. Asthmatic-type symptoms may develop and may be immediate or delayed up to several hours. Ingestion: Do not induce vomiting. If patient is conscious and can swallow, give two cups of water or milk (16 oz.). Get immediate medical attention. Never give anything by mouth to an unconscious or convulsing person. 4.2 Most Important symptoms/effects, acute and delayed:
Signs and Symptoms: Irritation as noted above. Skin sensitization (allergy) may be evidenced by blisters, redness,
or rashes, especially hives. Aggravated Medical Conditions: Preexisting skin and eye disorders may be aggravated by exposure to this
product. Preexisting skin and lung allergies may increase the chance of developing increased allergy symptoms from exposure to this product. Other Health Effects: Based on animal studies, repeated exposure to components of this product may cause damage to respiratory systems. Reports have associated repeated and prolonged occupational exposure to solvents with
permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling vapors may be harmful or fatal. 4.3 Indication of immediate medical attention and special treatment needed, if necessary:
Note to Physician:
Eyes: Stain for evidence of corneal injury. If cornea is burned, instill antibiotic/steroid preparation frequently. Workplace vapors could produce reversible corneal epithelial edema impairing vision. Skin: This product is a known skin sensitizer. Treat symptomatically as for contact dermatitis or thermal burn. Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is contraindicated because of the irritating nature of the product. Inhalation: This product is a known pulmonary sensitizer. Treatment is essentially symptomatic. An individual having a dermal or pulmonary sensitization reaction to this material must be removed from any further exposure to any isocyanate. Contact a Poison Control Center for additional treatment information. Health studies have shown that many
petroleum hydrocarbons pose potential human health risks, which vary from person to person. As a precaution, exposure to liquids, vapors, mists, or fumes should be minimized.
5.0 FIRE-FIGHTING MEASURES 5.1 Suitable extinguishing media: Use foam, dry chemical, water spray, or CO2.
5.2 Specific hazards arising from the chemical: Flash Point is >200°F. Closed containers may explode when exposed
to extreme heat or burst when contaminated with water (CO2 evolved).
5.3 Special protective actions for fire-fighters: Full emergency equipment with self-contained breathing apparatus and
full protective clothing should be worn by firefighters. During a fire, HDI vapors and other irritating, highly toxic
gases may be generated by thermal decomposition. Use water spray to cool fire-exposed surfaces and to protect
personnel. Try to cover liquid spills with foam. Solvent vapors are heavier than air and may travel a considerable
distance where they may linger and/or find an ignition source and flash back.

6.0 ACCIDENTAL RELEASE MEASURES 6.1 Personal precautions, protective equipment and emergency procedures:
Evacuate nonessential personnel. Ventilate the area. Avoid breathing vapor. Use self-contained breathing apparatus or supplied air for large spills or confined areas. 6.2 Methods and materials for containment and clean up: Contain spill if possible. Prevent entry into sewers and
waterways. Cover spill with sawdust, vermiculite, Fuller’s earth, or other absorbent material. Pour decontamination
solution over spill area and allow reacting for at least 10 minutes. Collect material in open containers and add further
amounts of decontamination solution. Remove containers to a safe place, cover loosely, and allow to stand for 24 to
48 hours. Wash down spill area with decontamination solutions.
Decontamination Solutions: 1. nonionic surfactant Union carbide’s Tergitol TMN-10 (20%) and water (80%) 2. concentrated ammonia (3-8%), detergent (2%), and water (90-95%). Dispose of in accordance with federal, state, and local regulations.

11.0 TOXICOLOGICAL INFORMATION 11.1 Likely routes of exposure: N/A
11.2 Symptoms related to the physical, chemical and toxicological characteristics:
Eye Contact: Irritating and will injure eye tissue if not removed promptly. Prolonged vapor contact may cause conjunctivitis. Skin Contact: Isocyanates react with skin protein and moisture and can cause severe irritation. Has been known to cause allergic skin reaction in humans. Prolonged contact may cause blisters. Cured material is difficult to remove. Inhalation: High vapor concentrations are irritating to the eyes and respiratory tract causing runny nose, sore throat, coughing, chest discomfort, shortness of breath, and reduced lung function (breathing obstruction). The solvent vapors are anesthetic, cause headaches and dizziness and may have other central nervous system effects, including death. As a result of previous repeated overexposures or a single large dose, certain individuals will develop isocyanate sensitization (chemical asthma), which will cause them to react to a later exposure to isocyanate at levels well below the TLV. Sensitization may be either temporary or permanent. Ingestion: Can result in irritation and possible corrosive action in the mouth, stomach tissue, and digestive tract. Vomiting may cause aspiration of the solvent resulting in chemical pneumonitis. 11.3 Delayed and immediate effects and also chronic effects from short and long term exposure: N/A

Retro-Coat™ Floor Care Instructions
Retro-Coat™ provides the highest level of chemical resistance and vapor intrusion protection available. To
maximize the products effectiveness simple care instructions should be followed to ensure Retro-Coat will
provide a long-term solution to vapor intrusion.
Cleaning and Maintenance of Retro-Coat
Overtime the gloss of Retro-Coat will fade and staining may occur when Retro-Coat comes in contact with
chemicals spilled on the coating surface. Any change in color or fade in the coatings appearance is due to a PH
change on the coatings surface and is not the result of products “breaking down.”
The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor
with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner,
preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry.
Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor.
Additional steps can also be taken to prolong the look and life of a seamless floor:
1. Protect the floor during transference of heavy equipment
2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well
as keeping the metal forks lifted
3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt,
on the coating
4. Eliminate all metal wheels
5. Change over the light-colored polyurethane wheels
6. Do not slide heavy metal totes, drums or bins across the floor. Use pallets!
7. Immediately hose down chemical spills, especially on newly laid floors, which normally take a full seven
days to fully chemically cure
8. Ask Land Science Technologies the safe window before returning the floor to service. Just because the
floor can safely take foot traffic, does not mean it is ready for motor traffic

Small Repairs
A vital component to floor maintenance is making small repairs to any holes, gouges or cracks that might
develop overtime. Such needs occur due to removal of equipment, moving of walls, additions of drains,
substrate movement and abnormal wear and tear. Repair to such areas can be done quickly and is
recommended to repair such areas before the damaged area increases and results in large-scale repairs and
possibly building downtime. Small kits are available for building maintenance personal to make spot repairs as
needed.

Figure 1. Assembled VAPOR PIN®

Installation Procedure:

1) Check for buried obstacles (pipes,
electrical lines, etc.) prior to proceeding.

2) Set up wet/dry vacuum to collect drill
cuttings.

3) If a flush mount installation is required,
drill a 1½-inch (38mm) diameter hole at
least 1¾-inches (45mm) into the slab.
Use of a VAPOR PIN® drilling guide is
recommended.

4) Drill a 5/8-inch (16mm) diameter hole
through the slab and approximately 1-
inch (25mm) into the underlying soil to
form a void. Hole must be 5/8-inch
(16mm) in diameter to ensure seal. It is

5) Remove the drill bit, brush the hole with
the bottle brush, and remove the loose
cuttings with the vacuum.

6) Place the lower end of VAPOR PIN®
assembly into the drilled hole. Place the
small hole located in the handle of the
installation/extraction tool over the vapor
pin to protect the barb fitting, and tap
the vapor pin into place using a dead
blow hammer (Figure 2). Make sure the
installation/extraction tool is aligned
parallel to the vapor pin to avoid
damaging the barb fitting.

Figure 2. Installing the VAPOR PIN®

During installation, the silicone sleeve will
form a slight bulge between the slab and the
VAPOR PIN® shoulder. Place the protective
cap on VAPOR PIN® to prevent vapor loss
prior to sampling (Figure 3).

Figure 3. Installed VAPOR PIN®

7) For flush mount installations, cover the
vapor pin with a flush mount cover, using
either the plastic cover or the optional
stainless-steel Secure Cover (Figure 4).

Figure 4. Secure Cover Installed

8) Allow 20 minutes or more (consult
applicable guidance for your situation)
for the sub-slab soil-gas conditions to re-
equilibrate prior to sampling.

9) Remove protective cap and connect
sample tubing to the barb fitting of the
VAPOR PIN®. This connection can be
made using a short piece of TygonTM
tubing to join the VAPOR PIN® with the
Nylaflow tubing (Figure 5). Put the

Means (Figure 6). For flush-mount
installations, distilled water can be
poured directly into the 1 1/2 inch
(38mm) hole.

Figure 6. Water dam used for leak detection

11) Collect sub-slab soil gas sample or
pressure reading. When finished, replace
the protective cap and flush mount cover
until the next event. If the sampling is
complete, extract the VAPOR PIN®.

Extraction Procedure:

1) Remove the protective cap, and thread
the installation/extraction tool onto the
barrel of the VAPOR PIN® (Figure 7).
Turn the tool clockwise continuously,
don't stop turning, the VAPOR PIN® will
feed into the bottom of the

FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this
compound is likely to be biased on the high side.
L-05
Duplicate relative percent difference (RPD) is outside of control limits. RPD is a less useful indicator of sample
precision for sample results that are <5 times the reporting limit (RL).
R-04
Continuing calibration verification (CCV) did not meet method specifications and was biased on the high side for
this compound.
V-06
Calibrations RSD for this compound is >30% but <40%.Z-01

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate
carcinogenic risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values
if indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these
chemicals are likely not associated with vapor intrusion.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate
carcinogenic risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these
values if indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are likely not associated with vapor intrusion.

Raw materials in these products contain respirable crystalline silica as an impurity. The total crystalline silica in these products is < 0.55% for
Ready-mix joint compounds and < 0.90% for Blue Dot Light Weight Taping. Under normal conditions, the use of these products is not
expected to result in exposure to respirable crystalline silica that exceeds the OSHA PEL (0.05mg/m3). However, actual exposures to
respirable crystalline silica on a given jobsite must be determined by workplace hygiene testing.

SECTION 4: First Aid Measures
4.1. Description of first aid measures:
Inhalation: If breathing is difficult, remove affected person to fresh air and keep at rest in a position comfortable for breathing. If exposed or
concerned: Get medical attention.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. If
irritation persists, get medical attention.
Skin Contact: If on skin, wash with plenty of soap and water. If skin irritation or rash occurs get medical advice. Take off contaminated
clothing and wash it before reuse.
Ingestion: If swallowed, call a POISON CENTER or doctor. Rinse mouth. Never give anything by mouth if victim is rapidly losing
consciousness, or is unconscious or convulsing.
4.2. Most important symptoms / effects acute and delayed:
Inhalation: Exposures to airborne dust may cause irritation to the upper respiratory tract; symptoms of exposure may include sneezing,
coughing and sore throat.
Prolonged or repeated exposure to fine airborne crystalline silica dust may cause damage to lung tissue, a disease called silicosis. Symptoms
of silicosis include cough, shortness of breath upon exertion and chest tightness. The symptoms of silicosis develop following long-term
exposures to airborne dusts containing silica. May cause lung cancer by inhalation.

8.2. Exposure controls:
Engineering Controls: General ventilation is adequate for application of product in its original form. If airborne particulates are generated,
monitor concentrations in air and provide local exhaust ventilation when any exposure guideline is exceeded. Dust collection systems must
be designed and maintained to prevent the accumulation and recirculation of respirable silica into the workplace air.
If engineering controls and work practices are not effective in controlling exposure to this material or if adverse health symptoms are
experienced, wear suitable personal protection equipment including approved respiratory protection.
Eye/Face Protection: Wear safety glasses or goggles.
Skin Protection: Wear protective gloves; e.g. nitrile gloves. Where workplace conditions generate dust, wear protective clothing. Launder
contaminated clothing before re-wearing, or discard.
Respiratory Protection: When dust or spray concentrations in air exceed the occupational exposure guideline, wear an approved air-
purifying respirator.
NIOSH recommendations for Crystalline silica (respirable dust); concentrations in air:
Up to 0.5 mg/m3: particulate respirator equipped with an N95, R95, or P95 filter (including N95, R95, and P95 filtering facepieces) except

Personal protective equipment
Respiratory protection : When workers are facing concentrations above the occupa-
tional exposure limits they must use appropriate certified
respirators.
When atmospheric levels may exceed the occupational ex-
posure limit (PEL or TLV) NIOSH-certified air-purifying respi-
rators equipped with an organic vapor sorbent and particulate
filter can be used as long as appropriate precautions and
change out schedules are in place.
For emergency or non-routine, high exposure situations, in-
cluding confined space entry, use a NIOSH-certified full face-
piece pressure demand self-contained breathing apparatus
(SCBA) or a full facepiece pressure demand supplied-air
respirator (SAR) with escape provisions. Hand protection

Remarks : Chemical resistant protective gloves should be worn to pre-
vent all skin contact. Suitable materials may include chloro-
prene rubber (Neoprene) nitrile rubber (Buna N) chlorinated
polyethylene polyvinylchloride (Pylox) butyl rubber depending
upon conditions of use.
The suitability for a specific workplace should be discussed
with the producers of the protective gloves. Eye protection : Tightly fitting safety goggles (chemical goggles).
Wear face shield if splashing hazard exists.
Eye wash bottle with pure water
Tightly fitting safety goggles
Wear face-shield and protective suit for abnormal processing
problems. Skin and body protection : Cover as much of the exposed skin as possible to prevent all
skin contact.
Suitable materials may include
saran-coated material
depending upon conditions of use.
Choose body protection according to the amount and con-
centration of the dangerous substance at the work place. Protective measures : Wear protective clothing as necessary to prevent contact.
Eye wash fountains and safety showers must be easily ac-
cessible.
Observe the appropriate PEL or TLV value. Hygiene measures : Wash soiled clothing immediately.
Remove contaminated clothing immediately and clean before
re-use or dispose it if necessary.

Titanium dioxide (13463-67-7)

In lifetime inhalation studies of rats, airborne respirable-size titanium dioxide particles have seen
shown to cause an increase in lung tumors at concentrations associated with substantial particle
lung burdens and consequential pulmonary overload and inflammation. The potential for these
adverse health effects appears to be closely related to the particle size and the amount of the
exposed surface area that comes into contact with the lung. However, tests with other laboratory
aninals such as mice and hamsters, indicate that rats are significantly more susceptible to the
pulmonary overload and inflammation that cause lung cancer. Epidemiology studies do no
suggest an increased risk of cancer in humans from occupational exposure to titanium dioxide.
Titanium dioxide has been characterized by IARC as possibly carcinogenic to humans (Group
