Additional Indoor Air Sampling and Well Abandonment Report Bloomsburg Mills Brownfields Site 3000 Stitt Street
Monroe, North Carolina
H&H Job No. IME-001

1.0 Introduction and Background Information

Hart & Hickman, PC (H&H) has prepared this report to document post-Brownfields agreement
indoor air sampling conducted at the Bloomsburg Mills Brownfields Site located at 3000 Stitt
Street in Monroe, Union County, North Carolina (Site). A Site Location Map is provided as
Figure 1. In addition, this report provides documentation of the abandonment of monitoring and
remediation wells at the Site which was conducted concurrently with the indoor air sampling.

The Site consists of one parcel that is divided into two portions. The northern portion of the
parcel is approximately 3.8 acres, is located on the north side of Stitt St. and is currently vacant
land. The southern portion of the parcel is approximately 19.8 acres, is located on the south side
of Stitt St. and is developed with an approximately 207,000 sq ft building, an out of use water
tank, and parking and loading dock areas. A detailed Site map depicting the southern portion of
the Site is included as Figure 2. The western and southeastern portions of the building are
occupied by IMET Alloys (IMET) for the receipt, sorting, testing, cutting, cleaning, packaging,
and shipping of nickel and titanium alloys for the aerospace industry. The northeastern portion
of the building is occupied by Achem which performs cutting, limited printing, packaging, and
distribution of tape products.

The Site building was constructed in 1963 by Springs Industries, and Bloomsburg Mills acquired
the property in 1978 and operated at the Site until 2009. An addition was constructed on the
building prior to 1976. Springs and Bloomsburg used the Site building for textile dyeing and
finishing. A wastewater lagoon was also located in the northern portion of the parcel from the
late 1970s until it was closed in 2009.

S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
Bloom Industrial (unrelated to Bloomsburg Mills) purchased the Site from Bloomsburg Mills to
redevelop and lease the building to various tenants for industrial purposes. At that time, Bloom
Industrial began pursuit of a Brownfields agreement for the Site due to the presence of soil and
groundwater impacts associated with previous use of the Site for textile dyeing and finishing. In
August 2014, Bloom Industrial completed the Brownfields agreement with the North Carolina
Department of Environmental Quality (DEQ). IMET originally leased a portion of the Site
building from Bloom Industrial beginning in 2012 and, in April 2017, an affiliate of IMET
(IMET Properties LLC) purchased the facility from Bloom Industrial.

Previous assessment activities have been performed in conjunction with former petroleum
underground storage tanks (USTs) and former textile operations. These are briefly discussed
below.

Former USTs
• A 1,000-gallon gasoline UST was removed from the Site in 1989; however, the exact
location of the UST was not reported. Post-excavation soil sampling did not contain
detectable concentrations of gasoline range total petroleum hydrocarbons (TPH-GRO). In
a letter dated June 12, 1990, the DEQ indicated that no further action was warranted for
the UST.

• One 30,000-gallon No. 6 fuel oil UST was removed from the western side of the Site
building in 1993. The former location of the UST is depicted in Figure 2. Soil and
groundwater impacts were identified after removal of the UST; however, excavated soils
were placed back into the excavation due to reported concentrations of oil & grease
which were below the calculated final cleanup levels for the Site.

• Two 20,000-gallon No. 6 fuel oil USTs were removed from the northwestern side of the
Site building in 1994. The former locations of the USTs are depicted in Figure 2. Soil
and groundwater impacts were identified in association with the USTs after removal, and
3
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
approximately 917.13 tons of impacted soil was excavated and transported to Stalite
Environmental in Salisbury, North Carolina.

• Additional soil and groundwater assessments were conducted from 1996 through 1998
associated with the release of fuel-oil from the former USTs. The results of the additional
assessment activities revealed that the soil impacts did not exceed DEQ levels ant that
groundwater impacts were still present above North Carolina groundwater standards but
did not exceed the DEQ UST Section Gross Contamination Levels. The DEQ classified
the release as low risk and subsequently issued a risk-based no further action (NFA) for
the UT release incident, with a provision that groundwater was restricted for use as a
water supply, on October 20, 1998.

Former Textile Finishing Operations
In 1991, Bloomsburg Mills conducted an assessment of stained soil on the west side of the
building. The area was reportedly used to store drums during the time when the plant was
operated by Springs. Subsequently, additional soil and groundwater assessment were performed
on the west side of the building associated with the stained soil and former USTs (as noted
above) which indicated the presence of chlorinated volatile organic compounds (CVOCs)
(principally tetrachloroethene (PCE)) in groundwater.

The groundwater assessment indicated the presence of two areas of CVOC groundwater impacts,
one in the northwestern and one in the southwestern portions of the Site. The northwestern area
is believed to be associated with a PCE above ground storage tank (AST) that was located
outside the northwest corner of the building which was pumped to a process tank in the building.
The southwestern area is believed to be associated with maintenance activities conducted in
storage sheds and drum and equipment staging pad which were formerly located in that portion
of the Site. Groundwater flow was reported to be toward the northeast in the northwestern
portion of the Site and to the southeast in the southwestern portion of the Site.

Bloomsburg Mills conducted interim corrective actions at the Site which consisted of pumping
groundwater from two recovery wells to the wastewater lagoon located in the northern portion of
4
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
the Site parcel. The recovery system was installed in 2002 and operated at least until 2008.
According to the most recent groundwater sampling report, (Resolve Environmental Services,
PLLC, December 2008) PCE was detecting in MW-19 at a concentration of 40,500 micrograms
per liter (µg/L) which exceeded the North Carolina groundwater standard of 0.7 µg/L. MW-19 is
located outside the building in the northwestern portion of the Site. PCE was detected up to
1,790 µg/L in the northern part of the Site (MW-20), and up to 3,040 µg/L in the southern
portion of the Site (MW-22). PCE degradation products such as trichloroethene (TCE) were also
detected above North Carolina groundwater standards.

Vapor Intrusion Assessments
Previous vapor intrusion assessments were conducted in the Site building from 2011 to 2015 by
Resolve Environmental Services, PA (Resolve) and Harmon Environmental, PA (Harmon). As
part of the sampling, the building was given certain “Area” designations as shown in Figure 2
and briefly described below:
• Area 1 – IMET offices
• Area 2 – Achem offices
• Area 3 – IMET nickel and titanium solids handling and nickel washing
• Area 4 – Achem operations
• Area 5 – IMET vacant
• Area 6 – IMET nickel and titanium torch and shot blast
• Area 7 – IMET shipping

In January 2011, Bloomsburg collected soil vapor samples from below the building to evaluate
the potential for vapor intrusion concerns for the Site building associated with the soil and
groundwater impacts. The approximate locations of soil vapor samples are indicated in Figure 2.
The results of the soil vapor sampling indicated that only PCE was detected above current Non-
Residential Soil Gas Screening Levels (SGSLs) in samples collected from the northern portion of
the IMET solids handling space (Area 3; AS-1) and below the Achem space (Area 4; AS-7). The
locations of the previous soil vapor samples are indicated in Figure 3.

5
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
In September 2011, Bloom Industrial made improvements to the building which included filling
in some equipment pits in Area 3 and sealing the large cracks and gaps in the floor of the
building. In addition, Bloom Industrial applied two sealants on the concrete floor to minimize
vapor intrusion. IMET has also more recently filled in a pit in Area 5.

In October 2011, Harmon collected eight (8) indoor air samples on behalf of Bloom Industrial.
The samples were analyzed for a full list of volatile organic compounds (VOCs) and the sample
analytes were not limited based upon detection in soil vapor data. The results of the indoor air
sampling indicated that no CVOCs were detected above DEQ Non-Residential Indoor Air
Screening Levels (IASLs) with the exception of TCE which was detected at concentrations above
the screening level of 1.8 micrograms per cubic meter (µg/m3). TCE was detected in samples
AS-1 (6.2 µg/m3), AS-3 (2.4 µg/m3), and AS-4 (5.4 µg/m3), all of which are located in the far
northern and western portions of the building (Area 3). Note that because the IASLs are
conservative, the presence of a compound at a concentration above the IASL does not indicate
that vapor mitigation is warranted, only that additional evaluation may be warranted. In addition,
several petroleum-related volatile organic compounds (VOCs) were also detected above the Non-
Residential IASLs (naphthalene, toluene, xylenes, and 1,2,4-trimethylbenzene); however, these
compounds were thought to be associated with indoor air sources in the building and not vapor
intrusion. Further, petroleum-related VOCs and some CVOCs (including PCE and TCE) were
detected in the exterior background samples.

In July 2012, Harmon conducted another round of indoor air sampling. The results of analysis of
the indoor air samples indicated that PCE and/or TCE were detected above the Non-Residential
IASLs in samples AS-1, AS-3, and AS-4, collected from the far northern and western portions of
the building and AS-2 and AS-7, collected from the Achem space in the eastern portion of the
building. One petroleum-related compound (toluene) was also detected above the Non-
Residential IASL in sample AS-7.

As noted previously, a Brownfields agreement was completed for the Site in July 2014. The
Brownfields agreement included a provision that a work plan be submitted for DEQ approval for
additional indoor air sampling as part of the post-Brownfields agreement activities. A plan for
6
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
indoor air sampling was subsequently submitted to and approved by DEQ, and two additional
rounds of sampling were completed in January 2015 and July 2015. During both rounds of
sampling, soil vapor samples were collected concurrently with some of the indoor air sample
locations.

The results of analysis of the soil vapor samples collected in January and July 2015 indicated that
PCE and/or TCE were detected above Non-Residential SGSLs in sample AS-3 collected from
the far western portion of the building. No other compounds were detected above the Non-
Residential SGSLs.

The results of analysis of the indoor air samples collected in January and July 2015 indicated that
no CVOCs were detected at concentrations above the Non-Residential IASL with the exception
of 1,2-dichloroethane (1,2-DCA) and TCE. TCE and 1,2-DCA were detected above the Non-
Residential IASL in the sample collected in the IMET office area (AS-1), and TCE was detected
above the Non-Residential IASL in the sample collected from the far northwestern corner of the
building (AS-3) and norther wall of the building (AS-5). It should be noted that the 2015 sample
designations do not necessarily correspond to the same locations where samples with the same
sample designations were collected in 2011 and/or 2012. Several other VOCs were detected in
the samples above Non-Residential IASLs including toluene, benzyl chloride, and ethyl acetate
in the Achem space, and benzyl chloride, chloromethane, and ethyl acetate in the IMET offices.
Many of the non-chlorinated VOCs (including compounds detected above Non-Residential
IASLs) were detected at concentrations greater than the soil vapor concentrations indicating that
the presence of the non-chlorinated VOCs is primarily attributable to indoor air sources and not
soil vapor intrusion.

2018 Indoor Air Sampling Work Plan
Based upon discussions with DEQ Brownfields during due diligence for purchase of the Site by
IMET Properties LLC, DEQ requested that an additional round of indoor samples be collected
because of the time since completion of the 2015 samples and the possible influence of work
place products on the previous indoor air sampling results.

7
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
In November 2017, H&H and IMET personnel met at the Site to review Site conditions and the
locations of proposed indoor air samples. In January 2018, H&H submitted a work plan for
additional indoor sampling, and the work plan was revised in March 2018 based upon DEQ
comments. As part of the work plan preparation, H&H conducted a review of compounds that
are being used by IMET and Achem that appeared to have affected the previous indoor air
sample data.

IMET uses small quantities of various substances which generally include the alloy material,
welding gases, sulfuric acid (used to neutralize the waste oil), oils and fuels, and cleaners. IMET
uses multiple petroleum-related compounds in its operations including oils (honing, hydraulic,
lubricating, cutting), xylenes, mineral spirits, adhesives, paints, and fuels. Achem uses small
quantities of chemicals such as petroleum-based printing inks, printing cleaners, and lubricants.
Furthermore, the facility cuts and prints on adhesive tape which contains products such as
acetates. Achem uses petroleum related products (WD-40, toluene, release coats, and inks) and
propanol and propyl acetate.

Our review of the previous indoor air data, soil vapor data, and product inventory indicated that
the products used by IMET and Achem contain compounds of concern which have been detected
in indoor air at the facility including, but not limited to, aromatics (i.e., toluene, xylenes, etc.),
naphthalenes, acetone, cyclohexane, heptane, and hexane. Many of these compounds have been
detected in indoor air at concentrations greater than soil vapor confirming that they are from an
indoor air source.

Based upon our evaluation, it is very likely that most of the non-chlorinated VOCs previously
detected in indoor air in the Site building are associated with use at the facility and not from
vapor intrusion. As such, in the 2018 indoor air sampling work plan, H&H proposed and DEQ
approved analysis of the indoor air samples for the CVOCs of concern at the Site (see Section 2.1
below). The methods and results of the additional indoor air sampling conducted in 2018 are
discussed in Section 2.0 below. In addition, the methods and results of well abandonment
activities conducted concurrently with the indoor air sampling are provided in Section 3.0.

S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
2.0 Indoor Air Sampling

On June 12, 2018, H&H collected five indoor air samples from within the Site building. The
locations of the samples are depicted in Figure 3 and were located in the following areas:
• HHIA-A was collected in the Achem space (Area 4)
• HHIA-B was collected in the southern portion of the building (Area 6)
• HHIA-C was collected in the IMET offices (Area 1)
• HHIA-D was collected from the northwestern portion of the IMET solids processing area
(Area 3)
• HHIA-E was collected from the western portion of the IMET space which is currently
vacant (Area 5)

For quality assurance/quality control purposes one duplicate indoor air sample (DUP-1) was
collected at the HHIA-D location. In addition, two background outdoor air samples were
collected, one from near the main loading dock near the southeastern portion of the building
(HHBA-A) and one from an upwind location outside the IMET and Achem offices (HHBA-B).
The locations of the indoor air and background samples are indicated in Figure 3.

2.1 Indoor Air Sampling Methodology

The indoor and background air samples were collected using laboratory-supplied, 6-liter stainless
steel Summa canisters connected to in-line flow controllers with a built-in vacuum gauge. A 3-ft
long laboratory-supplied sampling cane was also connected to the flow controller so that the
sample intake point was positioned approximately 5 ft above grade (typical breathing zone
height). The flow controller was set by the laboratory to allow for the samples to be collected
over an approximate 8-hr period. The samples were collected during normal business hours and
conditions, the HVAC was operational within the IMET and Achem offices, and mechanical
ventilation fans operated in accordance with normal operating conditions.

9
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
Following set-up of the Summa canisters, the airflow regulator sample valves were opened and
the air samples were collected over an approximate 8-hour period. As part of the sampling event,
H&H periodically measured exterior wind speed and direction, indoor and outdoor temperature,
and indoor/outdoor air pressure differential. A tabular summary of the results of the field
measurement data (including temperature, barometric pressure, wind direction and speed, and
differential pressure) collected during the sampling is included in Table 1. As shown in Table 1,
the outdoor pressure was measured to be higher relative to the indoor pressure during the
sampling event. Differential pressure readings during sampling ranged from 0.002 inches of
water to 0.005 inches of water. Higher outdoor pressure as compared to indoor pressure may
increase the likelihood of vapor intrusion; as such, the samples were collected under an expected
“worst case” condition. As also shown in Table 1, the indoor air temperature ranged from 72
degrees Fahrenheit (oF) to 76oF while the outdoor air temperature ranged from 68oF to 75oF.

At the end of the 8-hour sample period, the sample canisters valves were closed and shipped
under standard chain-of-custody protocol to Pace Analytical Laboratory (Pace) for analysis of
select VOCs by EPA Method TO-15. In accordance with the approved work plan, the CVOCs
selected for analysis were the compounds detected during the previous sub-slab vapor sampling
conducted at the Site including tetrachloroethene (PCE), trichloroethene (TCE), carbon
tetrachloride, 1,1-dichloroethane, 1,1-dichloroethene, 1,2-dichloroethane, cis-1,2-dichloroethene,
trans-1,2-dichloroethene, vinyl chloride, and 1,1,2,2-tetrachloroethane.

In general accordance with the DWM Vapor Intrusion Guidance, H&H also completed the DEQ
Indoor Air Building Survey and Sampling Form during the sampling event which includes,
among other items, an inventory of chemicals in the Site building. The completed DEQ Indoor
Air Building Survey and Sampling Form is provided as Appendix A.

2.2 Indoor Air Sampling Results

The indoor air analytical results were compared to the February 2018 DEQ Non-Residential
Indoor Air Screening Levels (IASLs). A tabular summary of the indoor and background air
10
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
sample laboratory analytical results is provided in Table 2, and the laboratory analytical data are
provided in Appendix B.

The laboratory analytical results indicate that concentrations of CVOCs were either not detected
above the laboratory method detection limit (MDL) or were below the Non-Residential IASLs,
with the exception of TCE. TCE was detected in one sample located within Area 3 (HHIA-D) as
well as the duplicate air sample of HHIA-D (labeled DUP-1) at concentrations of 3.9 µg/m3 and
4.3 µg/m3, respectively, which are above the DEQ Non-Residential IASL of 1.8 µg/m3. HHIA-D
was collected in the northwestern portion of the building where the highest concentrations of
CVOCs have previously been detected. Other compounds detected in the June 2018 samples
below Non-Residential IASLs were PCE, TCE, and/or cis-1,2-dichloroethene (cis-1,2-DCE) in
samples HHIA-C and HHIA-D. CVOCs were not detected above the MDL in samples HHIA-A,
HHIA-B, HHIA-E, or either of the two background samples.

As indicated in Table 2, since modifications to the building were completed in 2011 to reduce
vapor intrusion potential (i.e., filling in pits, filling floor gaps and sealing floor), concentrations
of CVOCs have generally been stable to decreasing over time. As such, it is unlikely that indoor
air concentrations will increase in the future.

For quality assurance/quality control purposes, a field duplicate sample (DUP-1) was collected in
accordance with the approved work plan to evaluate the precision of the field sampling
procedures, sample matrix variability, and analytical reproducibility. The duplicate sample was
collected using a sample “T” such that the indoor air sample (HHIA-D) and duplicate sample
were collected simultaneously. The duplicate sample results were comparable to the results of
HHIA-D which indicate good analytical repeatability. The results for DUP-1 are provided in
Table 2.

11
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
2.3 Cumulative Risk Calculations

The IASLs are conservative screening levels that are based upon a Lifetime Incremental Cancer
Risk (LICR) of 1 x 10-6 for potential carcinogenic effects and a Hazard Index (HI) of 0.2 for
potential non-carcinogenic effects. Vapor intrusion mitigation for occupied industrial/
commercial structures is not typically considered unless the LICR exceeds 1 x 10-4 and/or the HI
exceeds 1.

To further assess the detected indoor air concentrations, H&H used DEQ’s Vapor Intrusion
Indoor Air Risk Calculator to calculate the cumulative risks using the CVOCs detected in indoor
air sample HHIA-D and its duplicate DUP-1. A copy of the risk calculations is provided in
Appendix C and the calculated LICRs and HI values are summarized below.

Sample
ID

Date Sample Location Non-Residential
LICR HI
HHIA-D 6/12/18 Area 3 1.7 x 10-6 0.55
DUP-1 6/12/18 Area 3 1.9 x 10-6 0.60

As noted above, the calculated LICR for indoor air sample HHIA-D/DUP-1 ranged from 1.7 x
10-6 to 1.9 x 10-6 which are within the acceptable risk range of 1 x 10-4 to 1 x 10-6. The
calculated non-carcinogenic HI values ranged from 0.55 to 0.60, which are below the acceptable
threshold level of 1.

For comparison purposes, H&H also calculated cumulative risks for the Site CVOCs detected in
the 2015 to 2018 sampling events for samples collected in Areas 1 and 3 where the highest
concentrations of compounds have been detected. A summary of those risk calculations is
provided below:
12

Sample
ID

Date Sample Location Non-Residential
LICR HI
AS-1 1/22/15 Area 1 1.5 x 10-6 0.47
AS-1 7/27/15 Area 1 1.6 x 10-6 0.52
HHIA-C 6/12/18 Area 1 7.2 x 10-8 0.019
AS-3 1/22/15 Area 3 9.1 x 10-7 0.29
AS-5 1/22/15 Area 3 1.3 x 10-6 0.42
AS-3 7/27/15 Area 3 4.5 x 10-7 0.14
AS-5 7/27/15 Area 3 1.4 x 10-6 0.45
HHIA-D 6/12/18 Area 3 1.7 x 10-6 0.55
DUP-1 6/12/18 Area 3 1.9 x 10-6 0.60

As indicated above, in the three sampling events conducted in January 2015, July 2015, and June
2018, cumulative LICRs calculated using detected CVOCs in the areas of highest compound
concentrations were all within or below the acceptable LICR risk range of 1 x 10-4 to 1 x 10-6,
and the calculated non-carcinogenic HI values were all been less than 1.
13
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
3.0 Well Abandonment

On June 11, 2018, H&H oversaw the abandonment of monitoring wells and recovery wells at
the Site by SAEDACCO, a licensed well contractor. In accordance with the Brownfields
agreement for the Site, H&H submitted an e-mail request to DEQ Brownfields notifying
DEQ of the well abandonment on January 31, 2018, and DEQ indicated that they had no
objection to the well abandonment in an e-mail dated April 17, 2018.

SAEDACCO abandoned the following 18 wells at the Site: MW-1, MW-2, MW4, MW-7,
MW-9, MW-10, MW-10A, MW-11, MW-13, MW-14, MW-15, MW-17, MW-17A, MW-19,
MW-20, MW22, RW-1, and RW-2. In addition, during the well abandonment activities,
wells MW-8 and MW-12 were found to have been previously abandoned. As noted in the
well abandonment request submitted to DEQ, H&H was unable to locate wells MW-3, MW-
5, MW-6, and MW-16, and these wells are presumed to have been lost or destroyed.

The locations of the wells and the well abandonment records are provided in Appendix D.
The wells were abandoned by removing and properly disposing of the surface completions of
the wells and then tremie grouting the wells from the surface with cement grout.

S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
4.0 Summary and Conclusions

H&H conducted additional indoor air assessment and well abandonment activities at the
Bloomsburg Mills Brownfields Site located at 3000 Stitt Street in Monroe, North Carolina. A
summary of the recent and previous assessment results is provided below:

• The results of the June 2018 indoor air sampling indicate that CVOCs were not detected
in indoor air samples at concentrations above the MDL or the Non-Residential IASL,
with the exception of TCE in one sample from the northwest portion of the building. TCE
was detected in indoor air sample HHIA-D and its duplicate DUP-1 at concentrations of
3.9 µg/m3 and 4.3 µg/m3, respectively, which are above the conservative Non-Residential
IASL of 1.8 µg/m3.

• The results of cumulative risk calculations for HHIA-D/DUP-1 indicate that the
cumulative LICR ranged from 1.7 x 10-6 to 1.9 x 10-6 which are within the acceptable risk
range of 1 x 10-4 to 1 x 10-6. The calculated cumulative non-carcinogenic HI values
ranged from 0.55 to 0.60, which are below the acceptable threshold level of 1.

• Since modifications to the building were completed to 2011 to reduce vapor intrusion
potential (i.e., filling in pits, filling floor gaps, and sealing floor), concentrations of
CVOCs have generally been stable to decreasing over time. As such, it is unlikely that
indoor air concentrations will increase in the future. In the three sampling events
conducted in January 2015, July 2015, and June 2018, cumulative LICRs calculated using
detected CVOCs in the areas of highest compound concentrations have all been within or
below the acceptable LICR risk range of 1 x 10-4 to 1 x 10-6, and calculated non-
carcinogenic HI values have all been less than 1.

• The monitoring wells and recovery wells at the Site have been properly abandoned.

15
S:\AAA-Master Projects\Imet Alloys\2018 IA Sampling\Report\Additional Indoor Air Sampling Report.doc
Based on the results of the indoor assessment activities which indicate stable to decreasing
indoor air concentrations with time and the acceptable risk levels during the last three sampling
events, vapor intrusion does not appear to pose a significant risk to current or future Site workers.
As such, H&H does not recommend further evaluation of the vapor intrusion pathway for the
Site building.

Cumulative: 1.7E-06 5.5E-01
All concentrations are in ug/m3
Output Form 3F
** - 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.
