SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1)POTWs with a design flow rate greater than or equal to 1.0 mgd;2)POTWs with a pretreatment program(or those that are
required to have one under 40 CFR Part 403);or 3)POTWs required by the permitting authority to submit data for these parameters.
• At a minimum,these results must include quarterly testing for a 12-month period within the past 1 year using multiple species(minimum of two
species),or the results from four tests performed at least annually in the four and one-half years prior to the application,provided the results
show no appreciable toxicity,and testing for acute and/or chronic toxicity,depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition,this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition,submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity,provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation,if one was conducted.
• If you have already submitted any of the information requested in Part E,you need not submit it again. Rather,provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used,report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below,they may be submitted in place of Part E.

1 .0 INTRODUCTION
This report presents the results of the June 2019 groundwater monitoring event as well as an
evaluation of an on-site groundwater recovery system from June 15, 2018 to June 3, 2019 at the
IR facility located at 501 Sanford Avenue in Mocksville, North Carolina (see Figure 1). The
purpose of the groundwater monitoring program is to monitor groundwater quality within and
downgradient of the observed volatile organic compound (VOC) plume in accordance with
Ingersoll Rand's RCRA Part B Permit(EPA ID No. NCD0414772) issued September 16, 2011.
Scope of Work
In accordance with the RCRA Part B Permit and the approved 2011 Groundwater Sampling and
Analysis Plan (GWSAP), ground water monitoring is performed at the site on an annual basis.
The 2018 sampling event is an annual event; therefore, the following wells and analyses
applied:

IR purchased an existing building in 1965 and started manufacturing rotary components and
portable air compressors. Currently, the company supports the production of rotary and centrifugal
air compressors for the Compression Technologies and Services division, reciprocating and rotary screw
compressors for the Thermo King division, and rotors and machined housings to support the Commercial
ERM 1 Mocksville GW Report 2019-07.docx

HVAC division. Manufacturing processes include steel fabrication, machining, painting, assembly,
and testing of air compressors and other assembled products.
The manufacturing plant occupies 417,350 square feet of floor space, with the two largest
buildings being the PMO (Machine Shop) Building and the PAO (Assembly) Building. The plant
historically operated an on-site surface impoundment facility, which consisted of a lagoon with
two hydraulically joined cells. The surface impoundment was located approximately 250 feet
west of the PMO Building. Waste was last received at the facility on November 7, 1985. This
portion of the facility is the focus of the ground water quality evaluation (see Figure 2).
Site Hydrogeology
Mocksville is located in the Piedmont Physiographic province of North Carolina. The
topography of the Piedmont is characterized by well-rounded hills and long rolling ridges.
The regional near-surface geology is composed of a complex assemblage of rocks forming
the Charlotte Belt. It is composed of igneous rocks, including diorites, gabbros, and
o granites that have intruded into metamorphic rocks that are generally metamorphosed
asedimentary and igneous types.
ra Two rock types, a metamorphosed granite and a gneiss, have been observed in borings
o beneath the Mocksville facility. These rock types generally appear at depths of
m approximately 15 to 60 feet. The overlying residual soils are alluvium and saprolite. This
weathered material contains the relict texture of the underlying rocks. The minerals
themselves have weathered to clays, silts and sands. The degree of weathering decreases
with depth. Residual soils and alluvium from depths of 10 to 30 feet overlie the saprolite
and are characterized as fine to coarse sands, silts and clays.

2.0 FIELDWORK ACTIVITIES
Ground Water Elevation Measurements
Water levels were gauged with the corrective action system in operation, on June 3, 2018). The
site recovery wells were sampled as part of the static water table gauging activities. The
groundwater recovery system was re-started upon completion of monitor well sampling activities.
Depth to groundwater in the wells was gauged using a decontaminated electronic water-level
probe capable of measuring the water level to within 0.01 foot. The measuring point for the wells
is the northernmost edge of the inner casing of the well. Monitor well construction information is
presented in Table 1 and water level data is summarized in Table 4 and Appendix A.
Groundwater Sample Collection
In accordance with the schedule presented in Section 1.0, ERM sampled and analyzed
extraction wells RA-2A and RA-3 for trichloroethylene (TCE) and tetrachloroethylene (PCE) by
EPA Method 8260B:
The extraction wells contain dedicated submersible pumps and discharge lines that discharge to
the Town of Mocksville's Cooleemee publically owned treatment works(POTW)facility. The well
pumps were started and allowed to run at least 30 minutes prior to sample collection from the
recovery wells. In-line spigots were used as sampling ports to collect water samples into
laboratory-provided containers.
For quality assurance and quality control purposes (QA/QC), the MW-10d sample was
duplicated and submitted as a blind sample to the lab, a field blank was collected using
deionized water and a trip blank sample were also analyzed. The field blank and trip blank were
analyzed for TCE and PCE by EPA Method 8260B.
The samples were immediately placed on ice inside insulated shipping containers, and then
delivered under the appropriate chain-of- custody protocol to Gulf Coast Analytical Laboratories
(GOAL) in Baton Rouge, Louisiana for analyses. A copy of the laboratory report is in Appendix
D.
Soil Sample Collection
Two soil borings were advanced in the vicinity of the former TCE waste handling area to profile
soil quality and stratigraphy in advance of planned enhancement of the current corrective action
system. The boring locations are shown in Figure 9. The borings were advanced and sampled
using rotosonic and geoprobe drilling equipment on May 16-17, 2019.
3.0 RESULTS
Groundwater Elevations and Flow
Groundwater flow in the surficial aquifer(saprolite and PWR ground water units) is to the west
generally following the topographic gradient and toward the groundwater extraction system (see
Figures 3A and 3B). The system creates a measurable area of drawdown that is sufficient to
capture the previously documented extent of TCE-affected groundwater. Groundwater in the
ERM 3 Mocksville GW Report 2019-07.docx

bedrock aquifer also flows to the west. Groundwater extraction from the overlying aquifer locally
affects groundwater flow in the bedrock aquifer, effectively creating a capture zone within the
aquifer, as shown on Figure 4.
Groundwater Analyses
Table 5 summarizes the results for target constituents during the June 2019 event. TCE was
detected in extraction well RA-2A at 282 pg/L, which is down from the 2018 detection of 528
pg/L (see Appendix B). TCE was detected in extraction well RA-3 at 493 pg/L, which continues
to be elevated above historic levels and suggests that the TCE plume originating in the PAO
building is migrating to this location (see Figures 5 and 6). The TCE concentration in deep
bedrock well MW-11d was 5,800 pg/L, which is the highest concentration to date. Historical
analytical data is included in Appendix B.
There were no target compounds detected in quality control samples (Field Blank and Trip
Blank) indicating that well samples were not cross-contaminated during field or transport
activities.
Additional Assessment and System Enhancement Activities
Boring VPB-01 was installed in the vicinity of the MW-24 monitor well pair, using a sonic drill
rig. The boring was advanced to approximately 108 feet below ground surface (BGS). Boring
VPB-02 was installed inside the PAO building, within an area previously identified with
elevated soil gas concentrations. This boring was installed using direct push technology to
approximately 50 feet BGS, when refusal was encountered.
Continuous soil samples were collected from each boring and samples obtained at 10-foot
intervals were submitted for laboratory analyses of volatile organic compounds (VOCs) by
EPA Method 8260. Boring logs are provided in Appendix G. Figure 9 shows VPB locations
and Figure 10 is a cross-section showing TCE concentrations with depth. The soil sample
laboratory report is provided in Appendix H.
The soil data indicate that the vertical extent of source area TCE in the saprolite aquifer is
limited, and does not extend to the top of the bedrock aquifer. This information will be used to
design one or more additional source area groundwater recovery wells. Additional soil data will
be collected from the source area as part of the installation of soil vapor pilot testing
infrastructure. This activity is planned for late August.
4.0 CORRECTIVE ACTION SYSTEM EVALUATION
Groundwater Recovery System
Ingersoll Rand facility personnel operate and maintain the ground water recovery system,
including inspection of each groundwater extraction well and recording total flow volumes from
each well, to contain groundwater impacts on the property. The extraction wells are effectively
removing TCE from the aquifer and preventing migration of the VOC plume. The volume of
ground water recovered during the 12-month period from June 15, 2018 to June 3, 2019 is
presented below:
ERVi 4 Mocksville GW Report 2019-07.docx

Well ID Volume(gallons) Average Pumping Rate (all wells) 12 gpm
RA-1 2,761,960 System design capacity(all wells) 25 gpm
RA-2A 419,920 12-month Mass Removal 15.2 lbs.
RA-3 3,448,490
Total 6,630,370
Groundwater TCE concentrations in extraction wells RA-2A and RA-3 over time are shown in
Figure 7. A graphic summary of the pounds of TCE removed per extraction well per monitoring
period is shown in Figure 8.
IR conducts monthly inspections of the former impoundment area and well network as
required by the RCRA Part B Permit. Site inspections have indicated that the former
impoundment area has remained covered and within a locked fence. Inspection logs are
included in Appendix E. Additionally, ERM has performed quarterly third party inspections of
the impoundment area and well network. ERM's inspection logs are included in Appendix F.
5.0 CONCLUSIONS
• Groundwater in the shallow and bedrock aquifers generally flows towards the on-site creek.
This flow is consistent with historical observations.
• The total amount of groundwater recovered from the corrective action system over the 12-
month period from June 15, 2018 to June 3, 2019 was 6,630,370 gallons, with a combined
average flow rate of 12 gallons per minute for all three pumping wells.
• TCE was detected in extraction well RA-2A at 282 pg/L, which is down from the 2018
detection of 528 pg/L. TCE was detected in extraction well RA-3 at 493 pg/L. Detections in
both wells suggests that the TCE plume originating in the PAO building is migrating toward,
and being captured by recovery wells R-2A and R-3.
• The TCE concentration in deep bedrock well MW-11 d was 5,800 pg/L, which is the highest
concentration to date. This increase over the 2018 concentration (3,780 pg/L) indicates a
continued migration of TCE from the upgradient(PAO area) of the site.
• The extraction wells are effectively removing TCE from the aquifer and preventing migration
of the VOC plume. This system also intercepts the TCE plume originating upgradient from
the system originating at the PAO building. This interception is evidenced by the increase in
TCE concentrations at RA-3 and the vertical profile as evidenced in shallow and deep
monitoring wells. Recovery well RA-1 continues to control hydraulic flow in the area of the
former impoundment but is no longer providing VOC mass removal.
• Monthly inspections of the former lagoon area and well network indicate that the
impoundment remains in good condition and within a locked fence. IR will continue monthly
inspections and will address any concerns identified.
• Two vertical profile borings were installed in May 2019 to characterize lithology and
contaminant mass near the PAO building source area. Soil sample analytical data from the
borings will be used in SVE system design and to refine the site conceptual model.
