Introduction This 2018 data summary report (DSR) discusses field work conducted and data collected in 2018 on Operable Unit 2 (OU-2) for the 700 South 1600 East Tetrachloroethene (PCE) Plume Superfund Site (site) in Salt Lake City, Utah. OU-2 includes PCE-contaminated groundwater extending downgradient from the area near the Veteran’s Health Administration (VHA) Medical Center into the Accelerated Operable Unit 1 (AOU-1) area. The AOU-1 area is generally located southwest of Mount Olivet Cemetery and is defined as the area where PCE-contaminated shallow groundwater (within 50 feet of the ground surface) and springs may result in potential risk from vapor intrusion (VI) into indoor air (EA, 2019) (Figure 1). Data quality objectives (DQOs) for the remedial investigation (RI) at OU-2 are described in detail in the Remedial Investigation Work Plan, OU-2 Remedial Investigation (RIWP) (CH2M, 2018a) and are summarized as follows: 1) Determine the source of the PCE plume identified by the U.S. Environmental Protection Agency (EPA) monitoring wells installed in 1998 and determine if there is sufficient mass of PCE in the vadose zone to act as an ongoing source of PCE in groundwater 2) Determine the lateral, vertical, and downgradient extent of the PCE plume identified by the 1998 EPA monitoring wells 3) Determine if PCE and daughter products measured in the East Side Springs (ESS) area (defined as the area where PCE and/or trichloroethene (TCE)-contaminated groundwater is present within 50 feet of the surface or discharges as seeps or springs) are related to the PCE plume identified by the 1998 EPA monitoring wells 4) Determine what hydrogeological features control PCE fate and transport in OU-2. If it is determined that the PCE plume extends into the AOU-1 area, determine what factors control the plume in the fault zone and if the entire plume discharges to the hillside or if some component continues further to the west 5) Determine the nature of the hydraulic connection between the PCE plume and production wells (SLC-18, University of Utah wells, and Mount Olivet Well) (Figure 1) 6) Determine if there are additional human and/or ecological exposure pathways in addition to VI in AOU-1, drinking water wells, and potential source-area soil and soil gas 7) Collect data to support possible remedial technologies including monitored natural attenuation, hydraulic containment, and bioremediation. Determine what natural attenuation processes are operating and estimate the rate of degradation of PCE and PCE daughter products The results presented in this DSR specially address the first phase (Phase I) of the RI. Several DQOs were not specifically addressed as part of Phase I but are expected to be addressed during later phases of the RI. The following Phase I field activities were conducted in 2018 to address the DQOs outlined in the RIWP (CH2M, 2018a): • Installed 18 shallow monitoring wells (including 7 monitoring well pairs and 4 individual wells) • Installed two deep monitoring wells: MW-03R (replacing abandoned EPA monitoring well MW-03 on the Veterans Administration [VA] Campus) and MW-08 (on 700 South near 1300 East) • Conducted groundwater sampling at previously installed EPA monitoring wells and monitoring wells installed in 2018 • Conducted quarterly surface water sampling from six locations in the AOU-1 area and three locations along Red Butte Creek • Performed a soil gas survey around VA Building 7 and along the sanitary sewer line that runs from Building 7, through Sunnyside Park, and joins the main sewer line that runs along Sunnyside Drive 2018 OU-2 Data Summary Report 1-2 AX0327191530SLC Field activities conducted and data collected during 2018 are discussed in the following sections. Interpretation of these data is being provided in the Conceptual Site Model Addendum, OU-2 Remedial Investigation, 700 South 1600 East PCE Plume, Salt Lake City, Utah (Conceptual Site Model Addendum; Jacobs, 2019). 2018 OU-2 Data Summary Report AX0327191530SLC 2-1 2. Shallow Groundwater Monitoring Wells A total of 18 shallow monitoring wells (including 7 shallow monitoring well pairs and 4 individual wells) were installed from June 18 to July 25, 2018 (Table 1; Figure 2). Four shallow monitoring wells and one shallow monitoring well pair were installed along the 1400 East Transect, upgradient of East High School and crossing the east branch of the Wasatch Fault (MW-18, MW-19, MW-20 shallow/deep [S/D], MW-21, and MW-22). The 1400 East Transect also includes the deep monitoring well MW-08 (Section 3) and is roughly perpendicular to groundwater flow from the VHA Medical Center toward the AOU-1 Area. Six additional shallow monitoring well pairs were installed in the AOU-1 area (MW-12S/D, MW-13S/D, MW-14S/D, MW-15S/D, MW-16S/D, and MW-17S/D) to refine the lateral and vertical extent of PCE in groundwater. Daily field activities were recorded in daily reports and field notebooks included in Appendices A and B, respectively. All appendices are provided in the electronic version of this report. 2.1 Utility Clearance and Permitting Utility clearance was performed by Blue Stakes of Utah 811 (Blue Stakes) and Ground Penetrating Radar Systems, LLC (GPRS). All identified utilities within a 20-foot radius of each monitoring well location was demarcated. Utility Locate reports are included in Appendix C. Prior to well drilling a Permit to Work in the Public Way (right-of-way [ROW] permit) was obtained for all shallow wells located within Salt Lake City ROW (14 of the 18 shallow wells), from the Salt Lake City Corporation Engineering Division. Well locations were approved by the Salt Lake City Department of Public Utilities and a $15,000 performance bond and a Certificate of Liability Insurance were submitted to Salt Lake City. Public Way permit materials are included in Appendix D-1. Traffic control plans were required to obtain Traffic Control Permits as part the ROW permit. These plans were developed by Jacobs Engineering Group Inc.’s (Jacob’s) subcontractor Utah Barricade and submitted to the Salt Lake City Community and Neighborhoods Division of Transportation. Traffic Control Permits were obtained for each well location prior to beginning work. Traffic Control Permits and Utah Barricade traffic control plans are included in Appendices D-2 and E, respectively. A noise permit application was submitted to the Salt Lake County Health Department (Health Department) prior to beginning work. After reviewing the application materials, the Health Department determined that a permit was not required for the work being performed. Although a permit was not required, the noise permit communications are included in Appendix D-3 to document that this information was submitted to the Health Department and that they determined a permit was not required. Two wells and one well pair (MW-18, MW-19, MW-20S/D) were located on the East High School campus (Figure 2). A Consent for Access agreement from the Salt Lake City School District was obtained for the East High School campus prior to drilling. The Consent for Access agreement is included in Appendix D-4 and includes access for routine monitoring well sampling for up to five years. 2.2 Drilling Hand-augering to 5 feet below ground surface (bgs) was attempted at all shallow well monitoring locations prior to drilling. Refusal was met prior to reaching 5 feet bgs at MW-13S, MW-18, MW-20D, MW-20S, MW-21, and MW-22. MW-13S and MW-21 were hand-augered to 4.5 feet and 3 feet bgs, respectively. Hydrovac was used at MW-19 and MW-20S to 5 feet bgs. Refusal occurred at MW-20D and MW-22 close to the ground surface. As no utilities were marked close to these locations, hand-augering was attempted for a minimum of 1 hour at these locations before progressing to drilling. Shallow wells were installed using a track-mounted remote-controlled Rotosonic (mini-Sonic) drill rig operated by Holt Drilling. Rotosonic drilling provides continuous core recovery which enables accurate 2018 OU-2 Data Summary Report 2-2 AX0327191530SLC visual logging of geologic units and contacts. Borehole logging was completed as outlined in the RIWP (CH2M, 2018a). Completed boring logs are included in Appendix F. Soil core photo logs are included in Appendix G. Archived soil core is stored in core boxes on the VA campus. Investigation-derived waste (IDW) was disposed of per the IDW management plan (CH2M, 2018a). IDW Profiles and manifests are included in Appendix H. Shallow well depths ranged from 15 feet bgs (MW-14S) to 150 feet bgs (MW-20D) (Table 1). Drilling was conducted from June 18 to July 25, 2018. The following well locations were adjusted from the tentative proposed locations outlined in the RIWP: • MW-12S/D were originally proposed to be located on McClelland Street near 800 South. Due to overhead power lines at this location, MW-12S/D were moved to the south end of McClelland Street, 35 to 40 feet north of the intersection of McClelland Street and 900 South (Figure 2). • MW-16S/D were originally proposed to be located at the corner of 800 South and Elizabeth Street. To accommodate business access in the area, MW-16S/D were moved approximately 140 feet north of the intersection of 800 South and Elizabeth Street (Figure 2). • MW-18 was originally proposed to be located on the north end of the East High School parking lot. This well was adjusted slightly north of its original location to maintain the planned spacing with the adjusted location of MW-20S/D. The well was also moved west into the green space adjacent to the parking lot as requested by the Salt Lake City School District. • MW-19 was originally proposed to be located on the southwest corner of the East High School parking lot. This well was moved north of its original location to accommodate the adjusted location of MW-20S/D. As with MW-18, this well was also moved west into the green space adjacent to the parking lot as requested by the Salt Lake City School District. • MW-20S/D were originally proposed to be located immediately west of the East High School football stadium. This location was adjusted northwest of its original location, into the green space south of the East High School parking lot (Figure 2). MW-20S/D was moved to avoid the steep slope and fenced area in the original location and to move the well closer to the east branch of the Wasatch Fault. • MW-22 was moved south into the green area south of the intersection between 1400 East and 900 South. The location was adjusted to reduce impacts to local traffic, provide a better workspace for drilling, and increase safety by providing larger buffer between the drill rig and residents in the area. A summary of shallow well locations, construction details, and depths are included in Table 1. 2.3 Geotechnical Testing Soil samples were collected from shallow well borings and submitted for the following geotechnical analyses: • Fraction of Organic Carbon (ALS Laboratory; ASTM D2974) • Laboratory mineralogical analysis (Microbial Insights; magnetic susceptibility) • Laboratory physical properties (Intermountain GeoEnvironmental Services, Inc. [IGES]): – Sieve (ASTM D6913) – Moisture content (ASTM D2216) – Dry unit weight (ASTM D7263) – Hydrometer (ASTM D422a) – Unified Soil Classification System (ASTM D2487) – Atterberg Limits (ASTM D4318) – Vertical Hydraulic Conductivity (ASTM D5084) Physical property testing of soil provides basic lithologic/geotechnical data to help identify and characterize hydrostratigraphic units for the conceptual site model. Hydraulic conductivity samples and dry bulk density samples were collected with a Shelby tube to provide undisturbed soil samples. 2018 OU-2 Data Summary Report AX0327191530SLC 2-3 The RIWP originally specified dry bulk density analysis (ASTM D2937) and vertical permeability analysis (ASTM D2434). These analyses were substituted for dry unit weight (ASTM D7263) and vertical hydraulic conductivity (ASTM D5084) respectively. Dry bulk density is typically used for fine-grained soils with known volume while dry unit weight can be used for more granular samples with irregular shapes. Although the tests are performed in a slightly different manner from each other, the data provided by both of these tests is similar. The hydraulic conductivity test was substituted for vertical permeability as it is more suitable for the fine-grained soils which were the types of soil selected for testing. Sample intervals and analyses were selected by the project manager and senior technical consultant based on a review of the subsurface conditions and the sample frequency outlined in the RIWP (CH2M, 2018a). Shallow monitoring well geotechnical results are tabulated in Table 2. Geotechnical laboratory reports are included in Appendix I. Validated foc data are included in Appendix J. 2.4 Shallow Monitoring Well Construction Drilling and construction of each shallow monitoring well was completed after the final borehole depth was reached. Final well design was determined in the field based on observed lithology and water levels after consultation with the field team leader, senior technical consultant, and the project manager as discussed in the RIWP (CH2M, 2018a). Shallow wells were constructed inside the drill casing with 2-inch diameter Schedule 40 polyvinyl chloride (PVC) casing and 2.5- to 10-foot 0.010-slot PVC screens. The filter pack was constructed using #20/40 mesh silica sand extending 1 to 2 feet above the top of the screened interval. 3/8-inch bentonite chips were installed above the filter pack to seal and backfill the borehole to approximately 3 feet bgs for the majority of the shallow wells. Four shallow wells (MW-18, MW-19, MW-20D, and MW-20S) that were deeper than the majority of the other shallow wells were backfilled with bentonite pellets to approximately 5 feet above the filter pack and Puregold grout to approximately 3.5 feet bgs. The Puregold grout was substituted for the neat Portland cement grout specified in the RIWP due to driller’s concerns about potential damage to the PVC from the heat of hydration of the cement. Temporary completions were installed for all shallow wells until all shallow well drilling and construction was complete. Final surface completions consisted of 8-inch steel vault flush-mount completions installed in high-strength concrete and in the manner specified by Salt Lake City. No water was added during monitoring well drilling or construction. Transducers were installed in MW-13D, MW-14S, MW-15D, MW-16D, MW-20D, MW-20S, MW-21, and MW-22. Screen intervals, pump intake depths, and transducer installation depths are included in Table 1. Shallow well construction diagrams are included in Appendix K. 2.5 Shallow Well Development Shallow monitoring wells were developed approximately 4 to 32 days after construction of each well was completed. The RIWP specified that well development would be completed 48 hours to 7 days after construction was complete. The timeline for well development was adjusted to increase efficiency for the drilling subcontractor, after confirming the change was acceptable with the U.S. Army Corps of Engineers (USACE). Well development for shallow wells that produced adequate water continued until a minimum of five borehole volumes of water were removed from the borehole and the final three consecutive water quality parameter measurements stabilized as described in the RIWP. Low-yield wells (MW-13S, MW-14S, and MW-17S) were bailed dry three times per the RIWP. Purge methods, purge volumes, and final water quality parameters are included in Table 3. Development logs and photos of the final development water are included in Appendix L. 2018 OU-2 Data Summary Report AX0327191530SLC 3-1 3. Deep Groundwater Monitoring Wells Two deep monitoring wells (MW-03R [total drilling depth 407 feet bgs], MW-08 [total drilling depth 420 feet bgs]) were drilled between October 8 and December 4, 2018 (Figure 2). MW-03R was installed on the VA campus to replace abandoned EPA monitoring well EPA-MW-03. MW-08 was installed west of the southwest corner of Mount Olivet Cemetery as the northern well in the 1400 East Transect. 3.1 Utility Clearance and Permitting Utility clearance was performed by Blues Stakes and GPRS. All utilities within a minimum 20-foot radius of each monitoring well were demarcated prior to drilling. Utility locate reports are included in Appendix C. An excavation permit was obtained from the VA prior to drilling MW-03R. All work on the VA campus was performed in compliance with the VA’s Stormwater Pollution Prevention Plan (SWPPP). SWPPP inspections are included in Appendix D-6. An ROW permit was obtained for MW-08 from the Salt Lake City Corporation Engineering Division. The location of MW-08 was approved by the Salt Lake City Department of Public Utilities and a $15,000 performance bond and a Certificate of Liability Insurance were submitted to Salt Lake City. Public Way permit materials are included in Appendix D-1. A traffic control plan was obtained from Utah Barricade for MW-08 and submitted to the Salt Lake City Community and Neighborhoods Division of Transportation. The Traffic Control Permit for MW-08 is included in Appendix D-2 and the Utah Barricade traffic control plan is included in Appendix E. A noise permit application for MW-08 was submitted to the Salt Lake County Health Department prior to beginning work. After reviewing the application materials, the Health Department determined that a permit was not required for the work being performed. Although a permit was not required, the noise permit communications are included in Appendix D-3 to document that this information was submitted to the Health Department and that they determined a permit was not required. 3.2 Drilling MW-03R was excavated to 7 feet bgs by hydrovac prior to drilling to ensure that no unmarked utilities were damaged by drilling equipment. MW-08 was hand-augered until refusal occurred at 2 feet bgs. Once refusal occurred it was determined drilling could proceed as no utilities were identified within 10 feet of the drilling location. A truck-mounted sonic rig operated by Cascade Environmental was used to drill and install deep monitoring wells. Borehole logging was completed as outlined in the RIWP and completed boring logs are included in Appendix F. Soil core photo logs are included in Appendix G. Archived soil core is stored in core boxes on the VA campus. IDW Profiles and manifests are included in Appendix H. MW-03R and MW-08 were drilled to total depths of 407 and 420 feet bgs, respectively. Final well depths were determined in the field based on the observed lithology and the push-ahead sample results. MW-03R drilling began on October 8, 2018, and was completed on November 7, 2018. MW-08 drilling began on November 14, 2018, and was completed on December 4, 2018. Well development, demobilization, and final site cleanup was completed by December 26, 2018. The location of MW-08 was moved approximately 250 feet west of the originally proposed location at the southeast corner of Mount Olivet Cemetery to reduce the noise level in the cemetery, as requested by USACE after receiving feedback from the VA and Mount Olivet Cemetery. MW-08 was moved to approximately 70 feet east of the intersection of 700 South and University Street (Figure 2). MW-03R and MW-08 locations, construction details, and total depths are included in Table 4. The installation of these two deep wells were performed as part of Phase I of the RI. The installation of additional deep wells specified in the RIWP will be completed in future phases of the OU-2 RI. 2018 OU-2 Data Summary Report 3-2 AX0327191530SLC 3.3 Geotechnical Testing Soil samples were collected from the deep well borings and submitted for the geotechnical tests outlined in Section 2.3. Sample intervals and tests were selected by the project manager and senior technical consultant based on a review of the subsurface conditions and the sample frequency outlined in the RIWP (CH2M, 2018a). Deep monitoring well geotechnical results are tabulated in Table 5. Geotechnical laboratory reports are included in Appendix I. Validated foc data are included in Appendix J. 3.4 Geophysical Logging Geophysical logging including natural gamma and neutron logging was conducted by Century Wireline in deep well boreholes, which complemented lithology observations, identified potential water-bearing units, and provided additional data to facilitate monitoring well design. Natural gamma logs are used to identify intervals with high clay content. Neutron logs are used to assess the saturated porosity in the subsurface. Nuclear magnetic resonance (NMR) logging was removed from the scope of work per Work Variance Notification #3 (CH2M, 2018b). The application of NMR will be re-evaluated once all deep wells have been installed. Geophysical logs are shown with lithology and push-ahead sample results in Appendix F. Complete geophysical logs are included in Appendix M. Geophysical logging was initially conducted to approximately 250 feet bgs in both MW-03R and MW-08 as this was the depth where the driller telescoped from the 9-inch drill casing to the 8-inch casing. The reason for logging prior to the installation of the 8-inch casing is that the introduction of a third casing (10-inch, 9-inch, and 8-inch) would decrease the accuracy of the logging above 250 feet. A second geophysical log was conducted from the surface to the total depth of the borehole after total depth was reached. The initial and final geophysical logs for MW-03R were conducted on October 19, 2018, and November 2, 2018. Geophysical logs in MW-08 were conducted on November 28, 2018, and December 4, 2018. 3.5 Push-ahead Groundwater Sampling Push-ahead groundwater samples were collected at vertical intervals of approximately 20 feet as outlined in the RIWP (CH2M, 2018a). If a sample could not be collected due to the inability to push the sampling device far enough into the soil to collect a sample, a groundwater sample was then attempted approximately 10 feet lower than the target interval. Push-ahead groundwater samples were collected in unpreserved 40-milliliter vials and stored on ice prior to being analyzed by a portable gas chromatography/mass spectrometer (Inficon HAPSITE [HAPSITE]) equipped with a headspace sampling system (HSS). This field screening method analyzed samples for PCE, TCE, and cis-1,2-dichloroethene (DCE) with a calibration range of 1 – 100 micrograms per liter (µg/L). To test the accuracy of the field screening method, duplicates of all samples collected from MW-03R were sent as field screening samples to ALS Laboratory in Taylorsville, Utah with a 24-hour turn-around time. One in ten samples were also sent to EMAX laboratory per the RIWP for confirmation laboratory analysis (CH2M, 2018a). HAPSITE and laboratory sample results are tabulated in Table 6. ALS push-ahead laboratory reports are included in Appendix I. Push-ahead groundwater sample logs are included in Appendix N. The HAPSITE/HSS method measured concentrations on average approximately 15 to 30 percent lower than laboratory concentrations, likely due to sample handling methods required to prepare samples for HAPSITE/HSS analysis (Table 6). Percent differences outside of this range (-45 percent at MW-03R at 327 feet bgs; 4 percent at MW-03R at 247 feet bgs) occurred when insufficient sample was available to run multiple samples on the HAPSITE/HSS due to sample breakage or high silt content. The field screening method was found to be reliable in comparison with the laboratory results for MW-03R and, as a result, was also utilized at MW-08. PCE concentrations with depth are shown graphically with borehole lithology and geophysical logs in Appendix F. TCE and cis-1,2-DCE measured below the field screening calibration limit of 1 µg/L for all samples (Table 6). Laboratory results ranged from non-detect to 1.1 µg/L for TCE and non-detect to 0.78 J µg/L for cis-1,2-DCE (J indicates a result above the method detection limit and below the reporting 2018 OU-2 Data Summary Report AX0327191530SLC 3-3 limit). Push-ahead results were instrumental in targeting well screen intervals in high PCE-concentration zones at both MW-03R and MW-08 and in determining the vertical extent of PCE contamination. Determining the lowest depth of PCE contamination also allowed total depth to be reached before the maximum proposed depth of 500 feet bgs. 3.6 Deep Monitoring Well Construction Final deep well designs were determined in the field after reviewing the lithology, geophysical results, and push-ahead sample results with the field team leader, senior technical consultant, the project manager, USACE, VHA, EPA, and the Utah Department of Environmental Quality. Deep wells were constructed inside the drill casing with 1-inch, 1.25-inch, and 2-inch Schedule 40-PVC casing. Schedule 80 PVC was specified for the deep wells in the RIWP (CH2M, 2018a). Screens consisted of 0.02-inch slot screens in 5- to 20-foot intervals. The filter pack was constructed using 10/20 silica sand (MW-03R) and 16/30 silica sand (MW-08) extending 1 to 2 feet above the top of the screened intervals. 3/8-inch coated and uncoated bentonite pellets were installed between each filter pack interval to seal the borehole between screen intervals. Baroid Quik-grout was installed above the uppermost 3/8-inch bentonite chip interval to approximately 20 feet bgs. Neat cement grout was used to backfill the borehole from 20 feet bgs to approximately 3 feet bgs. Baroid Quik-grout and neat cement grout were substituted for Portland cement grout due to the driller’s concerns about potential damage to the PVC from the heat of hydration of the Portland cement. Surface completions consisted of 16-inch diameter galvanized steel vault flush-mount completions in concrete (MW-03R) and high-strength concrete specified by Salt Lake City (MW-08). Screen intervals, pump types, and pump intake depths are included in Table 4. 3.6.1 MW-03R The tentative design for the construction of MW-03R outlined in the RIWP consisted of a ZIST well at a shallow interval within the first water zone, and a 5-inch well to monitor the highest concentration of PCE measured during push-ahead sampling. Upon review of the push-ahead sampling results and subsurface lithology, the design was revised to consist of four ZIST wells to allow for monitoring groundwater chemistry and water levels at four discrete intervals: • 215 to 220 feet bgs: a shallow interval to compare with existing EPA wells MW-01S and MW-02. • 267 to 272 and 307 – 312 feet bgs: intermediate intervals to monitor the higher concentrations of PCE measured during push-ahead sampling. • 359 to 364 feet bgs: a deep interval to provide long-term monitoring below the bottom of the plume. Replacing the proposed 5-inch well with additional ZIST well intervals precludes aquifer testing at MW-03R. However, the final design maximized the use of footage drilled and enables monitoring of multiple high-concentration PCE zones, provides a well in the same zone that MW-03 was screened across, and also provides a deeper vertical sentinel well (Jacobs, 2018a). 3.6.2 MW-08 The tentative design of MW-08 outlined in the RIWP consisted of two nested 2-inch monitoring wells with 10- to 20-foot long screens. Upon review of the lithology and push-ahead sample results, the design was revised to consist of two nested 2-inch monitoring wells and one ZIST well with the following screen intervals: • 91 to 106 feet bgs: 2-inch monitoring well with bladder pump screened in the transmissive zone where the highest PCE concentrations were found • 180 to 200 feet bgs: 2-inch monitoring well with bladder pump screened in the lower portion of the plume where PCE concentrations dropped to near the maximum contaminant limit (MCL) 2018 OU-2 Data Summary Report 3-4 AX0327191530SLC • 304 to 309 feet bgs: ZIST well screened in a transmissive zone with over 100 feet of non-detect field screening PCE results above it, providing a vertical sentinel well The revised MW-08 well design provides the added benefit of a vertical sentinel well below the plume and allows for chemical and water level monitoring for three intervals. In addition, the two 2-inch wells can be tested with slug tests as needed to measure hydraulic properties for the two transmissive intervals where contamination appears to be present. One-page boring logs with proposed well construction intervals are included in Appendix F. Construction diagrams are included in Appendix K. No water was added during drilling or monitoring well construction. 3.7 Deep Well Development The two bladder pump sampling intervals installed in MW-08 were developed using the bail, surge, and pump method until a minimum of five borehole volumes of water were removed from the wells and the final three consecutive water quality parameter measurements stabilized as described in the RIWP. The development of ZIST wells is recommended but not required by the manufacturer. However, each ZIST interval was developed to ensure the best possible sample. All MW-03R ZIST intervals were developed by low-flow. The MW-08C interval was developed using the manufacturer-recommended air-lift development alternative. This method was required at MW-08C due to initial high turbidity measurements in that interval. Development methods, total purge volumes, and final water quality parameters are included in Table 7. Deep well development logs and photos of final development water are included in Appendix L. 2018 OU-2 Data Summary Report AX0327191530SLC 4-1 4. Groundwater and Surface Water Sampling Groundwater and surface water sampling were conducted in Q3 (September 17 – October 10, 2018) and Q4 2018 (November 26 – December 27, 2018). Groundwater sample locations and select contaminant (PCE and TCE) concentrations are shown on Figures 3A and 3B. Surface water sampling locations and PCE and TCE concentrations are shown on Figure 4. Validated data are included in Appendix J. Groundwater and surface water sampling logs are included in Appendices O and P, respectively. IDW profiles and manifests are included in Appendix H. 4.1 Transducer Data Collection EPA well transducers were installed prior to the OU-2 RI and monitored by the U.S. Geological Survey through December 2017. Jacobs began quarterly data downloads in Q1 2018 for all EPA wells except for EPA-MW-06, which initially returned a communication error. The transducer in EPA-MW-06 was replaced and data downloaded in Q2 2018. Shallow well transducers were installed in Q3 2018; transducer data were initially collected for these wells in Q4 2018 (Table 8). Transducer depths and download dates are included in Table 8. Transducer field sheets are included in Appendix Q. Transducer data is included in an electronic data deliverable. 4.2 Groundwater Sampling Groundwater samples were collected from 18 shallow monitoring wells in Q3 2018 and in 18 shallow monitoring wells, 2 new deep monitoring wells (each consisting of multiple sample intervals), and 6 EPA monitoring wells in Q4 2018. Deep well intervals MW-03R-D (359 to 364 feet bgs) and MW-08C (304 to 309 feet bgs) could not be sampled in Q4 2018 as pumps were not installed in these intervals. The total number of ZIST pumps required for deep well installation was increased from what was originally assumed in response to the lithology and push-ahead groundwater sampling results. The ZIST pumps for these two intervals were not received from the manufacturer until after the Q4 2018 sampling round was complete. Groundwater sampling field parameters are summarized in Table 9. Overall, groundwater appeared to be aerobic with the exception of MW-13S, MW-14S, and to a lesser extent MW-03R-B (Table 9). These wells had negative Oxygen Reduction Potential (ORP) values and low dissolved oxygen concentrations (0.5 to 1.1 milligrams per liter [mg/L]), indicating possible reducing conditions at these locations. Groundwater sampling analytical results are discussed in further detail in the following subsections. Groundwater and surface water sampling analytes are listed in Table 10. 4.2.1 Volatile Organic Compounds Detected volatile organic compounds (VOCs) in groundwater are tabulated in Table 11. PCE and TCE concentrations in groundwater are also summarized on Figures 3A and 3B. The following shallow wells were sampled in both Q3 and Q4 2018 and had PCE concentrations above the MCL of 5 µg/L: Shallow Well ID Q3 2018 (PCE in µg/L) Q4 2018 (PCE in µg/L) MW-13S 31 22 MW-13D 69 67 MW-14S 10 3 MW-14D 37 30 MW-16S 23 20 MW-18 96 82 MW-19 89 72 MW-20S 5.2 4.4 MW-20D 12 11 2018 OU-2 Data Summary Report 4-2 AX0327191530SLC The following deep wells were sampled in Q4 2018 and had PCE concentrations above the MCL of 5 µg/L (CH2M, 2018a): Deep Wells Q4 2018 (PCE in µg/L) MW-01S 190 MW-02 160 MW-03R-B 220 MW-03R-C 6.5 MW-04 67 MW-08A 68 J MW-08B 5.5 Overall, PCE concentrations at the shallow wells remained relatively steady or decreased between the Q3 and Q4 2018 sample events (Table 11). All samples had TCE concentrations below the MCL of 5 µg/L (Table 11; CH2M, 2018a). 4.2.2 Semivolatile Organic Compounds Detected semivolatile organic compounds (SVOCs) are tabulated in Table 12. The only detected SVOC was bis (2-ethylhexyl) phthalate in MW-08B, MW-12D, MW-16D, MW-17S (Q4 2018), and MW-16S (Q3 2018). All detections were above the MCL of 6 µg/L and ranged from 6.4 J µg/L (MW-16D in Q4 2018) to 130 µg/L (MW-17S in Q4 2018) (Table 12; CH2M, 2018a). Bis (2-ethylhexyl) phthalate was not detected in consecutive sample events in shallow monitoring wells (deep monitoring well MW-08B was only sampled in Q4 2018). This compound was also not detected in adjacent or downstream monitoring wells including MW-13S/D, MW-14S/D, or MW-15S/D (Figure 2). 4.2.3 1,4-Dioxane Detected 1,4-dioxane results are tabulated in Table 13. There was only one detection of 1,4-Dioxane above the risk-based water screening level of 0.46 µg/L at MW-13S (0.47 J µg/L in Q3 2018). This compound measured below the method detection limit in MW-13S in the subsequent Q4 2018 sampling event. No MCL is established for this compound. 4.2.4 Pesticides Table 14 shows detected pesticides in groundwater samples. No pesticides were detected above MCLs or risk-based screening levels. The only detected pesticide was gamma-bhc (lindane) in MW-08B during Q4 2018. 4.2.5 Metals Groundwater metals concentrations are tabulated in Table 15. The following compounds were measured at concentrations greater than the MCL or risk-based screening levels outlined in the RIWP (CH2M, 2018a): • Aluminum: 2000 µg/L risk-based screening level – MW-17S: 4,570 µg/L in Q4 2018 • Arsenic: 10 µg/L MCL – MW-13S: 10.5 µg/L in Q4 2018 • Chromium: 100 µg/L MCL – MW-05R: 109 µg/L in Q4 2018 2018 OU-2 Data Summary Report AX0327191530SLC 4-3 • Cobalt: 0.6 µg/L risk-based screening level – Multiple detections; concentrations above screening level ranged from 0.626 J µg/L in MW-19 (Q4 2018) to 4.58 µg/L in MW-14S (Q3 2018) • Iron: 1,400 µg/L risk-based screening level – MW-13S: 2,810 µg/L in Q3 2018; 4,780 µg/L in Q4 2018 – MW-17S: 2,260 µg/L in Q4 2018 • Manganese: 43 µg/L risk-based screening level – Multiple detections; concentrations above screening level ranged from 60.5 µg/L in MW-19 (Q4 2018) to 1,530 µg/L in MW-14S (Q3 2018). • Nickel: 39 µg/L risk-based screening level – MW-05R: 79.2 µg/L in Q4 2018 MW-13S, MW-14S, and MW-03R-B had the highest manganese concentrations of all monitoring well locations (Table 15). Iron concentrations in these locations were all high relative to most monitoring well locations, ranging from 216 µg/L (MW-14S in Q3 2018) to 4,780 µg/L (MW-13S in Q4 2018). The combination of high concentrations of iron and manganese relative to other locations, low dissolved oxygen concentrations, and negative oxidation-reduction values is indicative that reducing conditions may be present in MW-13S, MW-14S, and MW-03R-B. Arsenic above the MCL in MW-13S may also be due to reducing conditions at this location. 4.2.6 General Chemistry General chemistry analytical results are tabulated in Table 16. General chemistry parameters include alkalinity, chloride, nitrate and nitrite as Nitrogen (N), sulfate, total dissolved solids (TDS), and total organic carbon (TOC). The range of concentrations in general chemistry parameters are as follows: • Alkalinity: 224 mg/L (MW-03R-B in Q4 2018) to 384 mg/L (MW-15S in Q4 2018) • Chloride: 73.8 mg/L (MW-03R-C in Q4 2018) to 439 mg/L (MW-15S in Q4 2018) • Nitrate and nitrogen as N: non-detect (MW-14S in Q3 2018) to 6.91 mg/L (MW-21 in Q4 2018) • Sulfate: 73.5 mg/L (MW-21 in Q4 2018) to 183 mg/L (MW-12D in Q3 2018) • TDS: 547 mg/L (MW-20D in Q4 2018) to 1,260 mg/L (MW-02 in Q4 2018) • TOC: 0.56 mg/L (MW-16D in Q3 2018) to 25.3 mg/L (MW-12S in Q4 2018) Low nitrate levels observed in MW-13S (0.36 – 0.73 mg/L) and MW-14S (non-detect to 0.6 ug/L) are a further indication that reducing conditions are present at these locations. 4.3 Surface Water Sampling Surface water sampling locations are summarized in Table 17 and shown with monitoring results on Figure 4. Surface water locations sampled in 2018 include five seeps/springs previously sampled and one new seep/spring added in 2018 (EA, 2016; Table 17). Three Red Butte Creek locations were also sampled including one previously sampled location and two new locations added in 2018 (Table 17). Although these locations are all described as surface water per the RIWP, two locations may be more indicative of shallow groundwater. SW-06 is a decorative well with a total well depth below the water table at its location, and SW-35 is a seep that surfaces from below ground level. Surface water sampling field parameters are summarized in Table 18. Surface water sampling analytical results are discussed in further detail below. Surface water sampling analytes are summarized in Table 10. 4.3.1 Volatile Organic Compounds Detected VOC concentrations in surface water are summarized in Table 19. PCE and TCE concentrations in surface water are also summarized on Figure 4. The following locations had PCE concentrations above the MCL of 5 µg/L: 2018 OU-2 Data Summary Report 4-4 AX0327191530SLC Location Q3 2018 (PCE in µg/L) Q4 2018 (PCE in µg/L) SW-06 15 38 SW-35 13 30 SW-39 14 18 SW-53 17 26 Surface water PCE concentrations increased between the Q3 and Q4 2018 sample events (Table 19). All sample results for TCE were below the MCL of 5 µg/L (Table 19). 4.3.2 Semivolatile Organic Compounds Detected SVOCs are tabulated in Table 20. The only detected SVOC was bis (2-ethylhexyl) phthalate in SW-47 (84 µg/L in Q4 2018), which measured above the MCL of 6 µg/L (CH2M, 2018a). Bis (2-ethylhexyl) phthalate was non-detect at SW-47 in Q3 2018 and at the other Red Butte Creek sample locations in both sampled quarters. 4.3.3 1,4-Dioxane Detected 1,4-dioxane results are summarized in Table 21. Four surface water sampling locations (SW-06, SW-39, SW-48, and SW-53) had detections ranging from 0.2 J µg/L (SW-48) to 0.35 J µg/L (SW-53). All results were below the 0.46 µg/L risk-based water screening level established for this compound (CH2M, 2018a). 4.3.4 Pesticides Table 22 shows detected pesticides in surface water samples. No pesticides were detected above MCLs or risk-based screening levels. The only detected pesticide was gamma-bhc (lindane) in SW-35 in Q4 2018. 4.3.5 Metals Surface water metals concentrations are tabulated in Table 23. The following compounds were measured at concentrations greater than the MCL or risk-based screening levels outlined in the RIWP (CH2M, 2018a): • Arsenic: 10 µg/L MCL – SW-35: 13.9 µg/L in Q3 2018 – SW-53: 29.7 µg/L in Q3 2018, 10.9 µg/L in Q4 2018 • Cobalt: 0.6 µg/L risk-based screening level – SW-35: 0.79 J µg/L in Q3 2018 – SW-53: 0.92 µg/L in Q3 2018 4.3.6 General Chemistry Surface water general chemistry analytical results are tabulated in Table 24. The range of concentrations in general chemistry parameters are as follows: • Alkalinity: 66.8 mg/L (SW-52 in Q3 2018) to 366 mg/L (SW-35 in Q3 2018) • Chloride: 38.6 mg/L (SW-52 in Q3 2018) to 473 mg/L (SW-53 in Q3 2018). • Nitrate and nitrogen as N: 0.50 mg/L (SW-51 in Q3 2018) to 3.7 mg/L (SW-34 in Q4 2018) • Sulfate: 19.5 mg/L (SW-52 in Q3 2018) to 341 mg/L (SW-53 in Q4 2018) • TDS: 150 mg/L (SW-51 in Q3 2018) to 1,320 mg/L (SW-53 in Q3 2018) • TOC: 0.55 J mg/L (SW-48 in Q3 2018) to 4.5 mg/L (SW-47 in Q3 2018) 2018 OU-2 Data Summary Report AX0327191530SLC 4-5 4.4 Groundwater and Surface Water Stable Isotopes Groundwater and surface water samples were submitted to the University of Utah’s Stable Isotope Ratio Facility for Environmental Research (SIRFER) laboratory for stable isotope analysis. As described in the RIWP and discussed further in the Conceptual Site Model Addendum, stable isotope data may offer insight into mixing relationships between different groundwater and surface waters at the site (CH2M, 2018a; Jacobs, 2019). Stable isotope data are tabulated in Table 25. SIRFER laboratory reports are included in Appendix I. 2018 OU-2 Data Summary Report AX0327191530SLC 5-1 5. Soil Gas Investigation A soil gas survey was conducted on the VA Campus and Sunnyside Park to help identify potential sources of PCE groundwater contamination. Samples were collected from four sample areas: the VA north area (located along Bennion Boulevard adjacent to Foothill Drive), outside VA Medical Center Building 7, along the sewer line on VA campus from Building 7 to Sunnyside Park, and along the sewer line through Sunnyside Park. An overview of soil gas sampling locations and sample areas is shown on Figure 5 and summarized in Table 26. Soil gas samples were collected in accordance with Modification #1 to the RIWP (RIWP Mod#1) with any variances noted in the sections below (Jacobs, 2018b). The soil gas survey included collecting soil gas samples from the locations shown on Figure 5, constructing soil gas probes in select locations to allow for future soil gas monitoring, and collecting soil samples from soil gas boreholes. Soil gas probes were constructed via hand-augering on the VA campus, and hand augering followed by direct push in Sunnyside Park. Temporary soil gas probes were constructed by installing the probe within 8/16 silica sand. Bentonite powder and hydrated bentonite granules were used to backfill the remaining hole to approximately 1-foot bgs. All-purpose sand was used to backfill the remaining borehole. Soil gas samples were collected in 1-liter Tedlar bags by lung box or purge pump and screened with a photoionization detector prior to being analyzed by a HAPSITE for PCE, TCE, and cis-1,2-DCE. All samples were run on the HAPSITE on the day of sample collection at an initial 1:10 dilution to prevent overloading the detector. Depending on the initial result, a second sample was run at a dilution within the calibration range of 1 – 100 parts per billion by volume. The total PCE, TCE, and cis-1,2-DCE concentrations were calculated using the HAPSITE dilution factor. At approximately one in ten soil gas sample locations, a SUMMA canister was also collected for laboratory analysis (EPA Method TO-15 full scan) for confirmation sampling. ALS push-ahead laboratory reports are included in Appendix I. Soil gas HAPSITE logs are included in Appendix N. Soil gas sample logs are included in Appendix R. IDW Profiles and manifests are included in Appendix H. Soil samples were collected on the VA campus from each sample location from cuttings obtained from the bottom of each soil gas sampling borehole using an EnCore sampler. Direct push was not utilized on the VA campus at the request of VA Engineering to avoid damaging the complicated network of utilities. Soil samples were collected from the bottom of each borehole as soon as possible after the cuttings were brought to the surface to minimize volatilization. Soil samples were collected from Sunnyside Park sample locations using disposable EnCore samples via direct-push. The RIWP Mod#1 specified that soil samples would be collected from Sunnyside Park locations where PCE was measured at 10 times the residential screening limit (140 micrograms per cubic meter [µg/m3]) or where obvious data anomalies were observed (Jacobs, 2018b). The screening level limit was not exceeded at any location in Sunnyside Park; however, soil samples were collected from the two deep soil boring locations below the sewer line after review of the data and in consultation between the field team leader, project manager, USACE, and VHA. 5.1 Utility Clearance and Permitting Utility clearance was performed by GPRS and Blue Stakes on the VA Campus and Sunnyside Park. All utilities were demarcated prior to excavation. Utilities are presented with the soil gas sampling locations on Figures 6 through 9. Note that some soil gas sampling locations were adjusted to avoid marked utilities. Utility locate reports are included in Appendix C. An access agreement was obtained from Salt Lake City Corporation to allow for soil gas survey and excavation. The access agreement is included in Appendix D-4. All work on the VA campus was performed in compliance with the VA’s SWPPP. SWPPP inspections are included in Appendix D-5. VA Excavation Checklists are included in Appendix D-6. 2018 OU-2 Data Summary Report 5-2 AX0327191530SLC 5.2 VA Campus All soil gas sample locations on the VA campus were hand-augered until refusal, to a maximum of 8.3 feet bgs, to prevent damage to utilities. Due to the limitations of this method, VA soil gas samples were collected above the sanitary sewer line, which was suspected to have potentially been used to discharge the PCE from the former dry-cleaning facility. The sewer line is estimated to be located at 10 to 12 feet bgs on the VA campus. VA soil gas sample depths ranged from 2.3 to 8.3 feet bgs. The RIWP Mod #1 stated that any soil gas probes that could not be hand-augered to 5 feet bgs would be abandoned and the probe moved and re-attempted at up to two adjacent locations (Jacobs, 2018b). Four soil gas locations (SG-08, SG-09, SG-11, and SG-19) were installed at depths less than 5 feet bgs on the VA campus after consultation with USACE and VHA (Table 26). Soil gas probes on the VA campus were installed with probe screens measuring 4-inches wide and 4- to 8-inches long. 8/16 Silica Sand was installed above each probe screen and the boring backfilled with bentonite granules to approximately 1 foot bgs. All-purpose sand was used to backfill the probe to the ground surface. Location SG-16 was originally slated to be installed on the VA campus south of SG-15 and northeast of SG-17. This location was not attempted as GPRS was not able to definitively mark all utilities in the area due to surface obstructions. VA soil gas sample locations are presented on Figures 6, 7, and 8. 5.3 Sunnyside Park Soil gas locations in Sunnyside Park are summarized in Table 26. All locations were hand augered until refusal prior to direct push sampling by a rig operated by Earthprobe. Soil gas probe depths ranged from 6 to 26 feet bgs. These sample depths are approximately at or below the sanitary sewer line, which was measured during the utility locate to be between 6.5 feet bgs in a manhole located at the north end of the park to 5 feet bgs in a manhole located at the south end of the park. Total depths to the sewer line measured in manholes in the park ranged from 2 feet bgs to 6.5 feet bgs. Soil gas samples in Sunnyside Park were initially collected using a purge pump. As a QC step, ambient air samples were also collected and run on the HAPSITE. During this quality control (QC) step, PCE was detected in ambient air samples, indicating a buildup of PCE was occurring within the purge pump between sample locations. It is likely low ambient air temperatures caused condensation to build up inside the purge pump, trapping PCE. As a corrective action, the lung box was substituted for the purge pump and ambient air samples were collected through the lung box. Lung box ambient air samples were non-detect for PCE, TCE, and cis-1,2-DCE. A new direct-push sample location (SG-44) was also added directly adjacent to one of the previous sample locations (SG-28) and sampled using the lung box. The PCE concentration was lower at SG-44 than SG-28, indicating the purge pump was artificially increasing PCE concentrations. Locations SG-24 through SG-31 were sampled using the purge pump; PCE concentrations measured in these locations are biased high, however, they are still relatively low compared to other soil gas sample locations (Table 27). The RIWP Mod #1 specified that additional soil gas locations may be collected to infill between sample locations or to step out from locations where PCE soil gas concentrations above the Industrial Soil Gas Vapor Intrusion Screening Level (VISLsg; 600 µg/m3) were measured. Two step-out locations (SG-40, SG-41) were sampled on the east and west side of SG-33 due to elevated PCE at that location, as described in further detail in Section 5.4 (Figure 9). Two deep soil gas probes (SB-42 and SB-43) were installed in Sunnyside Park. SB-42 was installed directly adjacent to SG-33, adjacent to Manhole MH-22658 and where elevated PCE was measured in soil gas (Figure 9). SB-42 was sampled until refusal occurred at a total depth of 27.75 feet bgs. Four screen intervals (6 to 7, 12 to 13, 16 to 17, and 24.8 to 26 feet bgs) were installed in silty gravel layers. SB-43 was installed adjacent to SG-35. Elevated PCE concentrations were measured at this location, which is immediately south/southwest of the three soil gas locations where the highest PCE concentrations were measured (Figure 9). SB-43 was sampled until refusal to a total depth of 17 feet bgs. Two screen intervals (7-8 and 14.7-15.7 feet bgs) were installed in silty sand with gravel layers. 2018 OU-2 Data Summary Report AX0327191530SLC 5-3 Each deep soil gas probe was centered within an 1-foot interval of 8/16 sand. Bentonite granules were placed between sand layers to seal the borehole. A 10-inch plastic flush-mount vault was placed at the surface and partially backfilled with all-purpose sand. Sunnyside Park soil gas sample locations are presented on Figure 9. SB-42 and SB-43 boring logs are included in Appendix F. Probe construction diagrams are included in Appendix K. 5.4 Soil Gas and Soil Sampling Analytical Results 5.4.1 Building 7 Area Exceedances of the PCE Industrial VISLsg (600 µg/m3) occurred at four locations in the Building 7 area (Table 27; Figure 6). Intermediate PCE concentrations (defined as between 10 percent of the screening level or 60 µg/m3 and the screening level) were measured to the east and south of Building 7. TCE was detected in SG-06 (31.3 µg/m3) and SG-04 (6.3 µg/m3) where elevated PCE concentrations were also measured. TCE in SG-06 exceeded the TCE Industrial VISLsg level of 29.3 µg/m3. Trace PCE concentrations (0.6 – 3.6 micrograms per kilogram [µg/kg]) were measured in 5 of the 15 Building 7 area soil samples. Data in this area is limited to a maximum depth of 8.3 feet bgs, two to four feet above the estimated depth of the sewer line. The high PCE concentrations measured adjacent to Building 7 indicates a possible source area in this location. 5.4.2 VA Sanitary Sewer Line Area PCE soil gas concentrations were generally lower in the VA sanitary sewer line area with a maximum sample depth of 8.1 feet bgs (Table 27; Figure 7). One intermediate (between 10 percent of the screening level or 60 µg/m3 and the screening level) PCE concentration was measured at SG-17, the northernmost sample location in that area. TCE in soil gas, and PCE and TCE in soil, were non-detect in the VA sewer line area. 5.4.3 VA North Area PCE soil gas concentrations in the VA North area ranged from 7.3 µg/m3 in SG-01 to 21.8 µg/m3 in SG-02 (Table 27; Figure 8). TCE in soil gas, and PCE and TCE in soil, were non-detect in this sample area. The sample depth was limited to 6.3 feet bgs. 5.4.4 Sunnyside Park Area Exceedances of the PCE Industrial VISLsg were initially measured at two locations in the Sunnyside Park area directly adjacent and to the south of Manhole MH-22658 (Table 27; Figure 9). The PCE Industrial VISLsg was also exceeded in a step-out sample location to the east of Manhole MH-22658 (Table 27; Figure 9). Intermediate (between 10 percent of the screening level or 60 µg/m3 and the screening level) PCE concentrations were measured to the west of Manhole MH-22658, in SG-32 to the north of the manhole, and in multiple locations to the south along the sewer line (Figure 9). Additional intermediate PCE concentrations to the north of Manhole MH-22658 are likely to be biased high due to the buildup of PCE in the purge pump used to sample SG-24 through SG-31. TCE in soil gas was detected at SB-42 below the Industrial VISLsg (5.4 – 18.8 µg/m3) in samples below 12 feet bgs (Table 27). Concentrations of PCE and TCE in soil gas increased with depth in SB-42. No other TCE detections were measured in the park area. Soil samples collected from SB-42 and SB-43 were non-detect for PCE and TCE. Data in this area were collected at or below the estimated depth of the sewer line. The high PCE concentrations measured proximal to Manhole MH-22658 indicates a likely PCE source in this area. 2018 OU-2 Data Summary Report AX0327191530SLC 6-1 6. Summary A summary of how the 2018 field work has advanced the stated data quality objectives is discussed in the following subsections. 6.1 PCE Plume Source Investigation Two PCE source areas were identified during the soil gas investigation: Building 7 on the VA Campus and near manhole MH-22658 in Sunnyside Park. PCE concentrations in soil gas samples collected adjacent to these areas exceeded the PCE Industrial VISLsg of 600 µg/m3. TCE also exceeded the Industrial VISLsg of 29.3 µg/m3 in sample location SG-06 adjacent to Building 7. At this time the vertical extent of PCE and TCE contamination in the identified source areas is not known. Trace PCE concentrations (0.6 – 3.6 µg/kg) were measured in 5 of 15 soil samples collected in the VA Building 7 area to a maximum depth of 8.1 feet bgs. PCE was non-detect in all 9 soil samples collected in Sunnyside Park to a maximum depth of 27 feet bgs. TCE was non-detect in all soil samples. The source area in the Building 7 area is not defined laterally to the north or west. The lateral extent of the source area in Sunnyside Park is also not fully defined. 6.2 Plume Nature and Extent PCE and TCE were non-detect or below the MCL in deep monitoring wells MW-05R and MW-06, bounding the plume to the north of the Guardsman Way Transect (Figure 3A). PCE and TCE were non-detect in MW-01D and in push-ahead sampling results corresponding to monitoring well intervals MW-03R-D and MW-08C, providing a possible vertical extent for the PCE plume in these locations. PCE and TCE were non-detect or below the MCL in shallow monitoring wells MW-21, MW-22, MW-17S/D, and MW-15S/D (Figure 3B). These wells are generally located south of monitoring wells with PCE above the MCL and provide a southern plume boundary in AOU-1. Downgradient wells MW-12S/D and MW-15S/D were also non-detect or below the MCL for PCE and TCE. 6.3 PCE and TCE in East Side Springs Area PCE and TCE were measured in shallow monitoring wells and seeps and springs in the ESS area (Figures 3B and 4). MW-18, located immediately east of the ESS area, was observed to have the highest concentration of PCE (96 µg/L in Q3 2018) (Figure 3B). The highest TCE concentration was observed in MW-14S (4.3 µg/L in Q4 2018). PCE was measured above the MCL in seep and spring sampling locations SW-35, SW-53, SW-06, and SW-39 (Figure 4). PCE and TCE were non-detect in the northernmost surface water sampling location (SW-48) and in all Red Butte Creek sampling locations (Figure 4). 6.4 Hydrogeology The installation and monitoring of additional monitoring wells improved the understanding of upper (shallow) and lower (deeper) groundwater flow in OU-2 (Figure 1). Shallow groundwater flows to the northwest east of Guardsman Way and to the southwest west of Guardsman Way (Figure 1; Jacobs, 2019). Deeper groundwater flows to the southwest overall (Figure 1; Jacobs, 2019). Further hydrogeological data inputs collected in 2018 including lithology, hydrostratigraphy data (foc, grain size distribution), geophysical logs, and geochemistry data (major iron chemistry and stable isotopes) are discussed in the Conceptual Site Model Addendum (Jacobs, 2019). 2018 OU-2 Data Summary Report 6-2 AX0327191530SLC 6.5 Hydraulic Connection to Production Wells The nature of the hydraulic connection between the PCE plume and production wells (SLC-18, University of Utah wells, and Mount Olivet well) will be characterized by evaluating groundwater sampling results, hydrogeological data inputs, borehole geophysical data, and aquifer test results. Aquifer testing is expected to be conducted after additional deep wells are installed. 6.6 Exposure Pathways Samples were collected from Red Butte Creek to determine whether surface water in Red Butte Creek has been impacted by PCE detected in monitoring wells. PCE and TCE were non-detect at all Red Butte Creek locations. 6.7 Remedial Technologies Data collected in 2018 including PCE daughter product concentrations; dissolved oxygen and ORP; redox sensitive ions and metals including sulfate/sulfide, nitrate, iron and manganese; oxygen and hydrogen stable isotopes; and magnetic susceptibility will be used to evaluate biological and abiotic attenuation processes. The extent to which natural attenuation processes may be operating is discussed further in the Conceptual Site Model Addendum (Jacobs, 2019). 2018 OU-2 Data Summary Report AX0327191530SLC 7-1 7.

A tailgate meeting was held, and the crew began performing pre-shift inspections and completing paperwork. Drilling resumed from 47 feet bgs. at 0825. The sound meter was set up 50 feet east of the rig tower and head unit. The maximum decibel reading was 97.3 and the average for the day was 75.4 dB. A portable restroom and wash station were brought on site. Casing, flapper, auger and core bits were delivered to site by Cascade. Two Cascade crew members picked up badges from Building 4. The badges had been issued and the drillers had not picked the badges up. The remaining crew member needs to be sponsored for badge. Lynne Welsh had stated during first kickoff meeting that as long as the prime contractor had a badge that we were ok to continue work until the physical badges for drillers were picked up. Lynne Welsh contacted Ryan H. to notify that Cascade had received a shipment of material to Building 7. Crew attempted to find the package with help from the receiving department and could not locate. At 1327 the jib for the rig hoist became inoperable with 60 feet of drill rod on the rack. The crew could not tower down to troubleshoot. The crew awaited Cascade technical support to locate a wiring diagram. At 1515 the crew completed a temporary repair of wiring for jib hoist. Cascade resumed drilling from 67 feet bgs. Cascade recovered the last run of the day from 67 to 76 feet for a total of 29 feet of depth drilled today. The jib hoist wiring shorted out after the final run of the day. The driller PAGE 2 OF 2 stated that Cascade would change out 4 lines to the jib hoist tomorrow a.m. Cascade left site at 1730.

The sound meter is set up 50 feet east of the tower and head. The maximum reading for the day was 99.9dB and the average was 75.7dB. Patrick O’Hara (Cascade drilling assistant) picks up badge from Building 4 at 0835. At 0940 the drill rod breaks while drilling second run of the day. Cascade pulls drill rod, attaches an over shot die to retrieve remaining rod and core barrel at depth. At 1010 Cascade notifies Jacobs that he’s unable to get a bite onto the drill rod. He believes the rod end has mushroomed preventing overshot from grabbing hold. Driller states that they will need to sacrifice a piece of 6” casing, cut the end off with a torch, and attach to overshot to capture rod. He asks if Cascade needs a hot work permit. Ryan H. calls David W. to discuss. To save time the decision is made for Cascade to fabricate the overshot at their shop in West Jordan. At 1030 Cascade leaves site for West Jordan. At 1040 Susanne Fairclough arrives on to inspect SWPPP documentation for the week. She asks that the inspection form be double checked for accuracy against the SWPPP plan. She requests that the potable water totes be labeled as such and to asks the crew to inspect other containers for labeling. Susanne leaves site at 1055. Cascade arrives back on site at 1335 with new over shot tool and begins tripping in drill string with tool attached. Cascade removed the broken rod and core barrel at 1420.

A tailgate meeting was held, and the crew began performing pre-shift inspections and completing paperwork. Two of the Cascade crew were new to the site and had to get VA badges. Jasin took Cascade to the badging offices to get their badges. Justin was able to get his badge processed, but Hunter was not in the system. Hunter will need to fill out the paperwork and submit it to the VA to receive a badge. The crew returned to the site and resumed drilling at MW-03R at 177’ bgs. Water was first encountered during the 187-197’ run. The sample for that run was not recovered at first and had to be redrilled. Because of this the water level was determined by waiting for the water to stabilize in the boring and measured. It was measured at 186.7’ bgs. The sound meter was set up 20’ in front of the front of the drill rig. Readings were collected for 3 hours, 21 minutes. The average noise level was 79.5 dB, and the max was 91.7 dB. The drillers broke for lunch and to pick up rubber tape to wrap on the push-ahead sampler. When they returned, the crew attempted to collect a water sample using the push-ahead sampler. They were only able to drive the sampler approximately 1 foot. They needed to push it 3’ to be able to expose the two-foot-long screen completely in native material. Because they couldn’t use the sampler, Jacobs collected a water sample using a bailer from the top of water to the bottom the boring (187-197’ bgs). The sample was placed on ice. After collecting the water sample, the crew continued drilling to a total depth of 207’ bgs. They then cleaned up the site, moved drill rods onto the support truck, and moved their trailer out of the gated area. The crew was off-site at 17:30.

When they arrived, Jasin noticed that there was a small leak coming from the side of the roll-off bin. Absorbent pads were placed under the leaks, and Jacobs called AET to bring out secondary containment to go underneath the roll-off bin. A tailgate meeting was held, and the crew began performing pre-shift inspections and completing paperwork. Ryan arrived and began arranging to get a second roll-off delivered and get secondary containment under them. Todd arrived shortly after to assist with the leak. The crew resumed drilling MW-03R at 207’ bgs. The push-ahead sampler was deployed after the 217’ run. The sampler was driven approximately 2 feet into native ground, then pulled back one foot. A water sample was collected by sending a bailer down the drill rods into the sampler. AET arrived and delivered a second roll-off bin and placed secondary containment under both bins. Jacobs dug up the soil where the water had leaked and placed it into the roll- off bin. The absorbent pads were also placed in there. Rachel collected a characterization sample from the roll-off bin. Cascade drilled to 236’ bgs. They attempted to take a water sample using the push- ahead sampler, but they were only able to drive the sampler 6” into native ground. Jasin decided to not collect the sample and will attempt to collect one after the next 10’ run. Cascade said that they will drill the next 10’ run in the morning, then do the geophysical logging, and then attempt to collect the push-ahead sample. The crews cleaned up the site, dumped the soil from the hoppers into the second roll-off, and left the site at 17:35 HEALTH AND SAFETY PAGE 2 OF 2 AM WEATHER: 42, P.C.

The drillers met refusal at 2 feet after hand auguring for 30 minutes. At 1200 attempts to remove obstruction were abandoned, the rig was towered back up, and drilling began. At 1300 Cascade had drilled to 37 feet. The driller notified Jacobs that the pre-bearing (main head bearing) has failed and the head will need to be replaced. Work stops while Cascade begins contacting management to troubleshoot issue, decide whether replacement parts will be needed, and find parts. Management to contact Cascade when the part is ready for pick up. At 1530 the resident at 701 South 1300 East (Tim) approached Cascade crew and began asking them questions. The crew referred them to Ryan H. The resident asked Ryan H. why the location of the borehole had been moved from “near the cemetery” to the road in front of his house. The resident also asked if the project schedule would run the entire 6 weeks, and if it would leave behind a stickup completion that would consume a parking spot on the road. He was mainly concerned about the lack of parking and when he would get his yard back. Ryan H. answered questions and provided the resident with the VA communications pamphlet. Cascade has talked with and waited to hear back from their management on part procurement. They have plumbed a device for draining the water from the pump. Jacobs and Cascade left site at 1605.

At 1045 the crew was approached by with Dan Avara (VA) about blocking off parking for further utility locate tomorrow morning. Jacobs discussed the proposed soil gas probe location map with Dan and decided that blocking off parking was unnecessary. Dan provided Jacobs with his card and asked that he be notified (preferably a day in advance) if the project will require maintenance to block parking in the future. At 1300 Dan Avara provided access to the fenced electrical area west of the maintenance building. Jacobs and GPRS left site at 1515. Jasin Olsen met AET at 08:30 at the MW-03R site to load and remove the remaining soil roll- off bin (bin #5956). Rain water that had collected in the secondary containment was pumped off into a water tote. The bin was loaded onto the truck and Susanne Fairclough signed the manifest. AET left the site at 10:40. Ryan Hamilton (Jacobs) and Larry Kellum (VA) arrived at the MW-08 drill site at 1025. Cascade arrived on site at 1035, began warming rig and performing pre-shift inspections. Jacobs, Larry and Cascade held a tailgate meeting. At 1145 the rig hydraulics were warm, and Cascade began tripping in drill string for cleanout to 217’ (total depth drilled by end of previous hitch). At 1235 the drill string was installed, and a bolt cap landed on the deck. The bolt had sheared from the mounting plate for the head tilt ram. The seal on the ram was bulging and the driller stated that the entire ram needed to be replaced. At 1245 Cascade left site for Tractor Supply. Cascade arrived back on site at 1425 and began replacement of tilt ram. At 1520 the driller stated that the hydraulic hose fitting on the new ram is smaller than the hose on the rig. Cascade leaves site for EVCO to pick up a fitting. At 1530 Larry Kellum leaves site. At 1614 Cascade arrived back on site and resumed repair of tilt ram. At 1635 the driller notified Jacobs that the new ram is 2 inches longer than the existing ram and will not work. He says that the new hydraulic ram was etched with the appropriate size, but the markings are incorrect. Cascade will procure a new ram through management and procurement. In the meantime, the Cascade field crew will attempt to rebuild the old ram to working condition. Cascade and Jacobs left site at 1655.

A GW sample was collected from 317 feet for HAPSITE analysis at 1110. At 1300 the field crew heard thunder with dark skies over head and stood down until 1330. At 1520 the push ahead sampler was deployed to 337 feet. The sampler was tagged using a water level indicator prior to retracting and exposing the screen. The inside of the sampler was dry. The sampler was retracted to expose the screen and several attempts were made to bail water from the sampler through the drill rod. Cascade went through two bailers and each became stuck and came up with no water. By 1620 the decision was made to forego further attempts to collect a sample. The rainwater in the secondary containment beneath the north roll off bin needed to be pumped off and hopper dumped. Cascade will attempt to collect a sample once more from 337 feet tomorrow morning and, if unsuccessful, will drill to 357 and collect a GW sample. By 1654 the rainwater from the secondary containment had been removed and soil cuttings from the hopper had been dumped.

MW-20S/D transducers were downloaded. Jasin and Tom left and went to Sunnyside Park, where there was a Blue Stakes meet scheduled for 9:00 am. At the Blue Stakes meet, the Salt Lake City utility locator showed up. ELM and Stake Center Locating had called previously to say that they did not need to come out because the markings were still visible from the previous meet. At 9:15, Jasin and Tom returned to the IDW storage area to get supplies to install the pumps in the deep wells. They went to MW-01S/D where they downloaded the transducer data and installed the pumps in the wells. MW-01S was installed at a depth of 204’ bgs. MW-01D was installed at a depth of 384’ bgs. At 15:00 they went to MW-02. They found that the bolts holding on the lid to MW-02 had been sheared off and the eyelets that the bolts tighten into were broken off (see photo). Salt Lake City has piled a sand/salt mixture right up to the well, and it is assumed that the loader moving the material around scraped the lid and broke the pieces. They opened the lid and found that the fittings that they had would not fit onto the well because it is surrounded by concrete and the fittings would stick up above ground surface. A different type of cap will be needed before the pump can be installed. They downloaded the transducers at MW-02, replaced the well cover lid, and left for MW-04. They arrived at MW-04, found that it would need a different style cap, downloaded the transducer and left for MW-06. At MW-06 they found that it would need a different style cap, downloaded the transducer, and left for the IDW yard. They returned to the IDW yard, stored supplies in the Conex, then left at 16:30.

Cascade began warming rig hydraulics and completing pre-shift inspection and field crew held a tailgate meeting. At 0825 Cascade crew member P. Ohara leaves site to get ice melt for rig platform. At 0830 a third attempt to collect a GW sample from retracted push ahead sampler at 337 feet is made using a bailer deployed through the drill string and into the sampler. The bailer comes up dry, most likely due to installation of push ahead sampler into lean clay fines. At 0850 Susanne Fairclough arrived on site for client oversight. At 0907 P. O’Hara arrives back on site and salts the ice on the rig platform. At 0915 Cacade begins tripping out drill string and push ahead sampler. At 1215 the push ahead sampler is installed to 357’ and tagged with a water level indicator prior to retracting the sampler to open the screen. By 1315 several attempts have been made to collect a GW sample using a bailer deployed through the drill rod into the push ahead sampler at 357’ and the bailer has no water and is not wet around the circumference of the bailer. At 1336 Ryan H. calls Todd Isakson to discuss path forward. The decision is made to continue drilling next 20 foot run to 377’ and attempt to collect a GW sample. Cascade begins tripping out drill string and push ahead sampler. At 1600 the push ahead sampler is deployed to 377’ and a water level indicator is used to confirm that water is not leaking into the drill string prior to retracting the push ahead sampler to expose the screen. The push ahead sampler is dry. By 1640 several attempts have been made to bail water from 377’. The bailer is dry with a small amount of fines on the end. Cascade and Jacobs begin loading up sample buckets and core boxes for transport to the IDW storage conex. At 1706 the site has been cleaned, equipment, core boxes and sample buckets loaded. At 1723 the core and samples had been stored. Cascade and Jacobs left site.

Cascade began warming rig hydraulics and completing pre-shift inspection and field crew held a tailgate meeting. At 0830 a GW sample was collected by deploying a bailer through the drill string and into the push ahead sampler at 377 feet. The retracted sampler was left overnight with the screen open to allow formation water from high fines content formation to fill the sampler. At 0925 Cascade began tripping out sampler. At 1150 an attempt was made to push a Shelby tube sampler from 380-383’. The drill string was pulled from the borehole and the sampler was not on the mounting bolts. The sampler was recovered while drilling from 377-397’ and was badly dented with disturbed soils inside. At 1355 the push ahead sampler was deployed to 397 feet. The sampler was tagged with a water level indicator prior to opening the screen. The sampler was dry. Lynne Welsh arrived on site at 1400 and left site at 1415. Cascade left site for lunch after opening the push ahead sampler screen and returned at 1450. An attempt was made to bail water by deploying a bailer through the drill string into the sampler. The bailer came up dry. The water level indicator was lowered to 397 feet and did not sound. The interval is not producing water. Jeremy Cox arrived on site at 1520 and left at 1550. At 1540 the driller stated that the drill crew needed to change out the jaws that allow them to break the pipe when tripping steel in and out of the borehole. By 1600 the jaws had been repaired. Cascade began cleanup around box truck and pumping off the secondary containment beneath the drill rig. The drill crew will drive the box truck and forklift to MW-03R laydown to load 80 feet of 8- inch casing for advancing borehole from 397 feet. By 1605 the water had been pumped from the secondary containment beneath truck. The box truck and forklift left site for MW-03R. At 1710 Jacobs and Cascade left MW-03R. The box truck will be loaded with casing after starting the drill rig tomorrow morning. HEALTH AND SAFETY AM WEATHER: 29, snow PM WEATHER: 36, snow TAILGATE TOPICS: Icy conditions (steady snow throughout day), hazards of loading casing in box truck, assessing risk prior to performing a new task.

Tangalos, R. Adams, T. Chalmers) arrived at Sunnyside Park at 07:30, meeting with Earthprobe (P. Casey, R. Glover) and USACE (G. Hattan). Team tailgate meeting performed, and daily PTSP completed and signed. Teams departed 08:00 for assigned tasks. Direct Push in Sunnyside Park: 08:00 – 16:00: Earthprobe and Jacobs performed direct push soil gas probe installation and sampling. All locations were hand augered prior to drilling until refusal. Auger depth ranged from 12 inches to 4 feet bgs. All non-dedicated equipment was deconned between boreholes using Alconox and distilled water. The following locations were completed or attempted:  SG-35. Auger to 36-inches. Direct Push total depth 15 ft bgs. Soil gas screen interval 14.0-15.0 ft bgs. Sampled using Tedlar bag for HAPSITE analysis at 09:01. PCE HAPSITE results = 81.1 ppbv (554.8 µg/m3). Summa canister normal sample collected; sample ID OU2-SG35-SC.  SG-36. Auger to 12-inches. Direct Push to total depth 15 ft bgs with soil gas screen interval 14.0-15.0 ft bgs. Unable to collect sample due to helium detection in purged gas, likely due to poor seal where tubing threads into drill point. Moved 1- foot south and re-drilled to 15 feet bgs total depth with soil gas screen interval 14.0-15.0 ft bgs; same issues as previous. Sample not collected at this location due to helium detections in Tedlar bag. Medium plasticity clay present at total depth.  SG-37. Auger to 48-inches. Direct Push to total depth 15 ft bgs with soil gas screen interval 14.0-15.0 ft bgs. Unable to collect sample due to helium detection in purged gas, likely due to poor seal where tubing threads into drill point. Moved 1- foot south and re-drilled to 15 feet bgs total depth with soil gas screen interval 14.0-15.0 ft bgs. No helium detected in Tedlar bag, so location sampled for HAPSITE analysis at 13:50. PCE HAPSITE results = 25.1 ppbv (170.4 µg/m3). Summa canister normal sample collected; sample ID OU2-SG37-SC. Medium plasticity clay present at total depth. PAGE 2 OF 4  SG-38. Auger to 36-inches. Direct Push to total depth 15 ft bgs with soil gas screen interval 14.0-15.0 ft bgs. Unable to collect sample due to helium detection in purged gas, likely due to poor seal where tubing threads into drill point. Moved 1- foot south and re-drilled to 15 feet bgs total depth with soil gas screen interval 14.0-15.0 ft bgs; same issues as previous. Sample not collected at this location due to helium detections in Tedlar bag. Medium plasticity clay present at total depth. 16:15: Earthprobe departs for off-site Geoprobe storage (Earthprobe garage). Jacobs (G. Tangalos) remains on site for conference call, and Jacobs (T. Chalmers, R. Adams) secure sampling equipment for charging and storage in the IDW yard, and return HAPSITE to VHA secure storage. 17:15: Jacobs direct push team off-site. Soil gas probe installation on VHA campus: 08:00: Jacobs (J. Olsen) rents core drill and 4” core barrel from Diamond Rental; 4-inch core barrel largest available. A lower gauge (heavier duty) extension cord is required than what is available on site, so a new extension cord was purchased to handle the draw of the core drill; additional safety cones and mats to cover the extension cord (where it would cross roadways) were also purchased. 10:10: Arrive at location SB-17. Two 100’ garden hoses and an extension cord were run from the back of Building 38 to SB-17 for asphalt coring. The garden hoses were attached to the core drill and are necessary to keep the bit from burning up. The hand auger would not fit through a single 4-inch asphalt core, and three were necessary. As the second core was being cut, silty discharge water from coring the asphalt was observed running towards the gutter. Coring was stopped and Jacobs (T. Chalmers) obtained the spill kit from the drill site. Using the spill kit, a dam was constructed using filter socks from the spill kit and bags of sand, thus preventing silt from entering the gutter. After the three asphalt cores were complete, the garden hoses were drained and stored to prevent freezing. Hand augering commenced at SB-17. 13:30: Hand auger at SB-17 reached refusal at 6’9”; more gravels and cobbles were present that in previous borings (see photo). From the bottom of the boring, Encore and moisture samples (OU2-SB17) were collected. The soil gas probe was constructed with 8/16 sand from 6’8” to 6’4” bgs, bentonite powder from 6’4” to 5’8” bgs, bentonite granules from 5’8” to 1’0” bgs, and play sand from 1’0” bgs to the surface. Construction of the soil gas probe was completed at 14:30. 14:30: The SB-17 area was cleaned up, and the tools were loaded into the field truck. 15:00: Jacobs returned to the IDW Yard, deconned equipment, stored supplies, and packed samples for shipment. 16:00: Jacobs (J. Olsen) depart VHA for FedEx.

Soil gas probe installation on VHA campus: Following tailgate meeting, Jacobs (J. Olsen, R. Hamilton, T. Chalmers) prepared to core drill asphalt on VHA campus. A 6-inch core barrel was rented to better facilitate hand augering. Six-inch cores were cut through asphalt at SB-18 and SB-19. Following the asphalt coring, augering began at SB-19; however, refusal was met at SB-19 at 3’9”. Moving forward, augering began at SB-18, and refusal was met at SB-18 at 2’. Following refusal at both locations, additional asphalt cores were cut at both locations. Greg Hattan (USACE) was consulted while visiting SB-19, and he had no objections to installing the probe if refusal was met prior to 5 feet bgs. In the re-cored location at SB- 19, refusal was again met at 4 feet bgs. Lynne Welsh (VHA) was consulted at her office after the team left the site, and she also agreed with building the probe at 4 feet bgs. On Friday, December 7th, a soil gas probe will be built at 4-feet bgs at the SB-19 location.

Olsen, T. Chalmers) arrived at the VHA IDW Yard at 07:30 and gathered necessary supplies to install soil probes. They arrived at SB-04 and completed the tailgate safety meeting, excavation checklist, and SWPPP inspection form. Soil gas probe installation on VHA campus: 08:00 – 16:45: Following tailgate meeting, Jacobs (J, Olsen, T. Chalmers) continued installing soil gas probes on the VHA campus. Hand auger and non-dedicated equipment deconned between locations. o 08:00-08:45: SB-04. Jacobs was able to get past the rock and continue hand augering to 5’10”. A soil gas probe was installed as described below:  5’10”: Total Depth  5’10” – 5’6”: Probe installed within 8 X 16 Silica Sand  5’6” – 5’0”: Bentonite powder  5’0” – 1’0”: Bentonite granules (hydrated)  1’0” – Ground surface: All-purpose sand o 08:45-12:30: SB-05. Soil boring location SB-05 was augered to 6’3”. Soil sample OU2-SB05 was collected the bottom of the soil boring. Following sampling, a soil gas probe was installed as described below:  6’3”: Total Depth  6’3” – 5’11”: Probe installed within 8 X 16 Silica Sand  5’11” – 5’1”: Bentonite powder  5’1” – 1’0”: Bentonite granules (hydrated)  1’0” – Ground surface: All-purpose sand PAGE 2 OF 3 o 12:30-14:00: SB-13. Hand augered to 2’2” and noticed that the boring kept filling up with water. It appears that the water is coming in from around the contact of road base above and a clay layer below. The water is only coming in from the east side of the boring. It would fill the boring to 1’11” bgs. They continued hand augering to refusal at 6’0”. Soil sample OU2-SB13 was collected from the bottom of the soil boring at 6’0”. The probe was constructed as described below:  6’0”: Total Depth  6’0” – 5’4”: Probe installed within 8 X 16 Silica Sand  5’4” – 4’6”: Bentonite powder  4’6” – 1’0”: Bentonite granules (hydrated)  1’0” – Ground surface: All-purpose sand The soil gas probe was placed on a ledge in the boring at 5’8”. This allowed for water to pool below it, hopefully keeping the water from saturating the probe. o 14:00-15:30: Cored through the asphalt at locations SB-08, SB-09, SB-11, and SB- 12. The cores were left in place to prevent tripping hazards and can be removed as each location is augered. o 15:30-16:30: Returned all supplies to the VHA IDW Yard and packed the soil samples to ship to the lab.

Jacobs and Cascade left Sunnyside Park for MW-08. On the way to MW-08 Jacobs and Cascade pass by MW-03R laydown area and see the dump truck leaving the RV parking lot after dumping 18 CY of road base for re-grade of the MW-03R parking area. The invoice states that a load of 16 CY of road base is still to come. Cascade and Jacobs arrive at MW-08 at 1255, hold tailgate meeting, review and sign off on APP. At 1340 the Cascade development rig is towered up over MW-08. At 1410 the depth to water in MW-08a is measured at 60.15’ bgs. The total depth of the well is measured at 104.5’ bgs. The depth to water in MW-08b is measured at 59.2’ bgs and the total depth of the well is measured at 200.4’ bgs. Wells MW-08a and b have approximately 1.9’ and 7.6’ of silt in the bottom respectively. At 1417 Cascade deploys a 20’ long PVC bailer with steel end cap and ball valve into MW-08a. By 1450 Cascade has bailed 5 times with a total of 15 gallons of water recovered. The silt content is decreasing with increased bailing effort. At 1505 a 5’x 1.75” steel surge block is deployed into MW-08a. The surge block becomes hung up at 40’ bgs. Cascade pulls the surge block and begins retrofitting using a 3’ length steel pipe. At 1525 the new surge block is assembled, and Cascade deploys into MW-08a. The surge block passes freely to total depth and Cascade begins surging the screen from top to bottom in 3-foot increments. By 1555 Cascade has surged the well screen for 30 minutes. The surge block is pulled from the well and the bailer is re- attached. At 1600 Cascade begins bailing the well. By 1615 MW-08a has been bailed 6 times with a total of 10 gallons of water recovered. The silt content decreases with each successive bail. At 1620 the total depth of MW-08 a is measured at 106.2’ bgs. The development effort has increased the total depth by 1.7’. Cascade begins cleanup and towers down development rig. At 1640 cleanup is complete and the rig has been towered down. Cascade and Jacobs leave site for MW-03R to drop off tow behind water tank. Cascade and Jacobs leave site at 1700.

SITE PHOTO LOG Appendix B Field Notebook Pages Appendix C Utility Locate Reports Subsurface Investigation to Locate Underground Utilities Prepared For: CH2M Hill/Jacobs Prepared By: Marc Snell Project Manager- UT, ID, MT 6/4/18 Page 1 of 6 June 4, 2018 CH2M Hill Attn: Jasin Olsen Site: Surrounding area of the VA Hospital. We appreciate the opportunity to provide this report for our work completed on 5/4/2018 at the above address in Salt Lake City, UT. PURPOSE The purpose of this project was to search for underground utilities within the project boundaries provided by the client within the VA Hospital Campus. Various soil borings are going to be made along the sewer line and as many obstructions as possible should be located. I (Reggie Griffiths) did most of the work, with some assistance of Marc Snell on 5/4/18 for mapping. EQUIPMENT • 400 MHz GPR Antenna. The antenna is mounted in a stroller frame which rolls over the surface. The surface needs to be reasonably smooth and unobstructed in order to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the feasibility of GPR. The data is displayed on a screen and marked in the field in real time. GPR works by sending pulses of energy into a material and recording the strength and the time required for the return of the reflected signal. Reflections are produced when the energy pulses enter into a material with different electrical properties from the material it left. The strength of the reflection is determined by the contrast in signal speed between the two materials. The total depth achieved can be as much as 8’ or more with this antenna but can vary widely depending on the conductivity of the materials. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link • Electromagnetic Pipe Locator. The EM locator can detect the electromagnetic fields from live power or radio frequency signals. It can also be used in conjunction with a transmitter to connect directly to accessible, metallic pipes, risers, or tracer wires. A current is sent through the pipe or tracer wire at a specific frequency and the resulting EM field can then be detected by the receiver. The receiver is moved over the surface without coming in contact with the ground so it is not affected by terrain. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. Depths achieved can be as much as 20’ depending on the type of signal being traced or methods used. For more information, please visit: Link • Traceable Rodder. The rodder has a copper wire encased in 5/16” of fiberglass. The line is pushed through accessible pipes before placing an electromagnetic signal on the wire which is then traced from the surface. The maximum traceable depth is 10’ depending on the soil conditions and the maximum distance is 300’. The line can be pushed through a pipe with direct access such as a conduit at a pull box or a storm drain catch basin. We will not be able to push through deeper pipes within manholes. The signal cannot be located through metallic pipes. For more information, please visit: Link • GPS. This handheld GPS unit offers accuracy down to +/-4 inches, however, the accuracy will depend on the satellite environment and obstructions and should not be considered to be survey-grade. Features can be collected as points, lines, or areas and then exported into Google Earth or overlaid on a CAD drawing. For more information, please visit: Link PROCESS Our process began with using the EM pipe locator to locate pipes or utilities throughout the scan area. We first sweep all areas with the receiver to detect live power or radio frequency signals followed by connecting to any visible risers or tracer wires that may be in the area provided that there is an exposed metallic surface. Locations and depths are painted or flagged on the surface. Depths cannot always be provided depending on the location method and can be prone to error. Initial GPR scans were then collected in order to evaluate the data and calibrate the equipment. Based on these findings, a scanning strategy is formed, typically consisting of scanning the entire area in a grid with 5’-10’ scan spacing in order to locate any potential utilities that were not found with the pipe locator. The GPR data is Page 2 of 6 interpreted in real time and anomalies in the data are located and marked on the surface along with their depths using spray paint, pin flags, etc. Depths are dependent on the dielectric of the materials being scanned so depth accuracy can vary throughout a site. LIMITATIONS Please keep in mind that there are limitations to any subsurface investigation. The equipment may not achieve maximum effectiveness due to soil conditions, above ground obstructions, reinforced concrete, and a variety o f other factors. No subsurface investigation or equipment can provide a complete image of what lies below. Our results should always be used in conjunction with as many methods as possible including consulting existing plans and drawings, exploratory excavation or potholing, visual inspection of above ground features, and utilization of services such as One Call/811. At this site, our scans were limited by curbs around landscaping and parking areas along with cars that were parked in the area. Some Utilities were not found do the lack of not being able to connect on the lines above ground. FINDINGS We found that the soil allowed for maximum GPR depth penetration of 2’-4’ in most areas. We were able to locate utilities such as gas, water, site lighting and sewer using either the GPR or RD. Various water lines throughout the side could not be accessed and traced out due to valve covers and tubes not being able to be remove d or were full of dirt. Various Pipes were found to share trenches. Please see provided map and overlay for further details.

PURPOSE The purpose of this project was to search for underground utilities within the project boundaries provided by the client within the VA Hospital Campus. A monitoring well is going to be placed within the area, and a clear area needs to be located. I (Reggie Griffiths) was the project manager on site performing the locating.

At the VA hospital site, the only limitation was the concrete barricades placed around the perimeter of the scan area. Near the cemetery on the city street, cars were parked along the road and rough terrain and landscape inhibited scanning. FINDINGS On the VA campus, we found that the soil allowed for maximum GPR depth penetration of 4’-6’ in most areas. We verified that any nearby utilities did not enter the scan area. The only concern found within the scan perimeter is with sight lighting. Please see provided map and overlay for further details. On the street near the cemetery, we identified the location of communication lines, water lines, sewer mains, and nearby power lines. We were unable to see the individual sewer laterals to the homes, nor could we locate th e gas lines (likely due to plastic pipe). Please see Google earth overlay for further details.

PURPOSE The purpose of this project was to search for underground utilities within the project boundaries provided by the client within the VA Hospital Campus. Various soil borings are going to be made along the sewer line and as many obstructions as possible should be located. I (Reggie Griffiths) did most of the work, with some assistance of Marc Snell on 5/4/18 for mapping. EQUIPMENT • 400 MHz GPR Antenna. The antenna is mounted in a stroller frame which rolls over the surface. The surface needs to be reasonably smooth and unobstructed in order to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the feasibility of GPR. The data is displayed on a screen and marked in the field in real time. GPR works by sending pulses of energy into a material and recording the strength and the time required for the return of the reflected signal. Reflections are produced when the energy pulses enter into a material with different electrical properties from the material it left. The strength of the reflection is determined by the contrast in signal speed between the two materials. The total depth achieved can be as much as 8’ or more with this antenna but can vary widely depending on the conductivity of the materials. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link • Electromagnetic Pipe Locator. The EM locator can detect the electromagnetic fields from live power or radio frequency signals. It can also be used in conjunction with a transmitter to connect directly to accessible, metallic pipes, risers, or tracer wires. A current is sent through the pipe or tracer wire at a specific frequency and the resulting EM field can then be detected by the receiver. The receiver is moved over the surface without coming in contact with the ground so it is not affected by terrain. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. Depths achieved can be as much as 20’ depending on the type of signal being traced or methods used. For more information, please visit: Link • Traceable Rodder. The rodder has a copper wire encased in 5/16” of fiberglass. The line is pushed through accessible pipes before placing an electromagnetic signal on the wire which is then traced from the surface. The maximum traceable depth is 10’ depending on the soil conditions and the maximum distance is 300’. The line can be pushed through a pipe with direct access such as a conduit at a pull box or a storm drain catch basin. We will not be able to push through deeper pipes within manholes. The signal cannot be located through metallic pipes. For more information, please visit: Link • GPS. This handheld GPS unit offers accuracy down to +/-4 inches, however, the accuracy will depend on the satellite environment and obstructions and should not be considered to be survey-grade. Features can be collected as points, lines, or areas and then exported into Google Earth or overlaid on a CAD drawing. For more information, please visit: Link PROCESS Our process began with using the EM pipe locator to locate pipes or utilities throughout the scan area. We first sweep all areas with the receiver to detect live power or radio frequency signals followed by connecting to any visible risers or tracer wires that may be in the area provided that there is an exposed metallic surface. Locations and depths are painted or flagged on the surface. Depths cannot always be provided depending on the location method and can be prone to error. Initial GPR scans were then collected in order to evaluate the data and calibrate the equipment. B ased on these findings, a scanning strategy is formed, typically consisting of scanning the entire area in a grid with 5’-10’ scan spacing in order to locate any potential utilities that were not found with the pipe locator. The GPR data is Page 2 of 2 interpreted in real time and anomalies in the data are located and marked on the surface along with their depths using spray paint, pin flags, etc. Depths are dependent on the dielectric of the materials being scanned so depth accuracy can vary throughout a site. LIMITATIONS Please keep in mind that there are limitations to any subsurface investigation. The equipment may not achieve maximum effectiveness due to soil conditions, above ground obstructions, reinforced concrete, and a variety of other factors. No subsurface investigation or equipment can provide a complete image of what lies below. Our results should always be used in conjunction with as many methods as possible including consulting existing plans and drawings, exploratory excavation or potholing, visual inspect ion of above ground features, and utilization of services such as One Call/811. At this site, our scans were limited by curbs around landscaping and parking areas along with cars that were parked in the area. There were also various vaults that could not be traced out found within the border provided by the client. The vaults are within a confined space and other outside sources were not able to locate the pipes inside the vault. There was also a sub station nearby that had very limited access. Some other locations with pipes coming out of buildings were also not accessible due to locked doors/limited entry. FINDINGS We found that the soil allowed for maximum GPR depth penetration of 2’ in most areas. We were able to locate utilities such as gas, water, site lighting and sewer using either the GPR or RD. We were not able to locate the Electrical lines in some vaults, nor irrigation lines. Various water lines throughout the side could not be accessed and traced out due to valve covers and tubes not being able to be removed or were full of dirt. Various Pipes were found to share trenches. Please see provided map and overlay for further details.

Subsurface Investigation to Locate Underground Utilities Prepared For: Jeremy Cox Prepared By: Mitchel Griffiths Project Manager- UT, ID, MT Completed 11/28/18 Page 1 of 2 November 28, 2018 Jacobs Attn: Jeremy Cox Site: VA Hospital Campus We appreciate the opportunity to provide this report for our work completed on 11/28/2018 at the above address in Salt Lake City, UT. PURPOSE The purpose of this project was to search for underground utilities within the project boundaries provided by the client within sunny-side park near the VA Hospital Campus. Monitoring wells are going to be placed within the area, and a clear area needs to be located. Both Mitchel and Reggie Griffiths were on site performing the utility locating, mapping, and re-marking the area. EQUIPMENT • 400 MHz GPR Antenna.

At the sunny-side park location, there were untraceable plastic lines (gas and water) in the area. There were also utilities in maps that were provided by the client that had no above ground structures to place a tone onto and a signal could not be found and the utility could not be traced or verified to be present. Also, the GPR could not penetrate deep enough to provide data. FINDINGS In sunny-side park near the VA Hospital campus, we found that the soil allowed for maximum GPR depth penetration of 2’. We verified that any nearby utilities did not enter the scan area, or marked out the utilities that were within 50’ of the sewer line. We also double checked each individual well location passively to ensure nothing was running through the proposed location. We identified electrical lines, water lines, sewer mains, storm drain lines and other unknown lines in the area that would cross the sewer. We were unable to see the individual sewer laterals to the nearby restrooms, nor could we locate the gas lines and water line to the west of the sewer line. (likely due to plastic pipe).

Introduction During the Operable Unit 2 (OU-2) remedial investigation on the Veterans Healthcare Administration (VHA) campus, soil gas samples were collected adjacent to VHA Buildings 6 and 7 in December 2018. This sampling was conducted to assess the presence or absence of volatile organic compounds (VOCs) (specifically tetrachloroethene [PCE], trichloroethene [TCE], and cis-1,2-dichloroethene [DCE]), in the vadose zone as part of an ongoing source area investigation. Elevated concentrations of PCE were detected in soil gas collected from approximately 5 to 8 feet below ground surface adjacent to Buildings 6 and 7. Concentration of PCE in soil gas in this area ranged from 14.8 to 3,130 micrograms per cubic meter (µg/m3). The U.S. Environmental Protection Agency (EPA) residential and commercial soil gas vapor intrusion screening levels (VISLs) for PCE are 140 and 600 µg/m3, respectively (Table 1) (CH2M, 2018). The results of this exterior soil gas sampling are provided in the 2018 OU-2 Data Summary Report (JACOBS, 2019). PCE concentrations in soil gas near Buildings 6 and 7 exceeded the residential and commercial soil gas VISL for PCE, thus a vapor intrusion (VI) investigation was conducted in these buildings. Buildings 13 and 20 were also included in the VI investigation because of the current building uses. Building 13 is currently a day care center and Building 20 is currently an extended-stay residential facility for veterans. Figure 1 presents the locations of VHA Buildings 6, 7, 13, and 20 and the area with known elevated PCE concentrations in soil gas. 2019 Indoor Air Data Summary Report BI0619191121SLC 2-1 2. Objective The objective of the VI investigation was to assess whether the VI pathway is complete and significant in Buildings 6, 7, 13, and 20. Significant in this context refers to the potential for VI-related exposures to correspond to excess lifetime cancer risks (ELCRs) above 1 × 10-5, non-cancer hazard indexes above 1, or both. The 1 × 10-5 target ELCR is the mid-point of the EPA target risk range (1 × 10-6 to 1 × 10-4) and has historically been applied to Accelerated Operable Unit 1 (AOU-1) VI investigations (EA, 2019). The VI investigation was guided by the AOU-1 Remedial Investigation Work Plan (FE, 2015) and its Minor Field Modification #18 (EA, 2017). Specifically, the VI investigation consisted of monitoring indoor air throughout each building, focusing on subsurface and ground level floors, with a field-portable gas chromatograph/mass spectrometer (INFICON HAPSITE [HAPSITE]). The indoor air monitoring throughout each building was conducted to provide spatial representation of concentrations of indoor air target analytes (cis-1,2-DCE, TCE, and PCE) to help evaluate: (1) the presence or absence of indoor background sources of target analytes, and (2) the potential for impacts to indoor air through the subsurface-to-indoor-air VI pathway. Daily field activities were recorded in daily reports and field notebooks included in Appendices A and B, respectively. HAPSITE native data results and calibration reports are presented in Appendices C and D, respectively. 2019 Indoor Air Data Summary Report BI0619191121SLC 3-1 3. Vapor Intrusion Investigation The following subsections summarize the VI investigation approach and results for Buildings 6, 7, 13, and 20. 3.1 Building 6 3.1.1 Indoor Air Monitoring The indoor air monitoring portion of the VI investigation at Building 6 was conducted on January 24 and 30, 2019. Building 6 is a two-story building (ground level and partial basement). Figure 2 presents the sample locations within Building 6. Table 2 presents the Building 6 indoor air HAPSITE results. No indoor air target analytes were detected in the northern portion of Building 6 on January 24, 2019. However, indoor air concentrations of PCE in the southern portion of Building 6 ranged from 17.40 µg/m3 (Plumbing Shop [location identification B6-IA-014]) to 915.69 µg/m3 (Electrician Shop, [location identification B6-IA-015]) (Figure 2, Table 2) on January 24, 2019. Additionally, indoor air concentrations of TCE in this same portion of Building 6 ranged from 0.73 (Operations Supervisor Office [location identification B6-IA-011]) to 7.13 µg/m3 (Electrician Shop, [location identification B6-IA-015]) (Figure 2, Table 2). The commercial Tier 2 removal action level (RAL) for PCE is 540 µg/m3 (Table 1). The commercial risk-based screening level (RBSL) and Tier 1 RAL for TCE is 3 and 8.8 µg/m3, respectively (Table 1). As shown on Figure 2, the southern portion of Building 6 does not exchange indoor air with the northern portion as these two areas are not connected with a hallway, door, or air-handling ducts. Multiple indoor background sources of PCE and TCE were identified within the Electrician Shop of Building 6 (Figure 2 [location identification B6-IA-015]) during the January 24, 2019 indoor air investigation. The indoor background sources were positively identified to contain PCE and TCE using the HAPSITE (Table 2) and are shown in Exhibit 1. These background sources were removed from Building 6 on January 25, 2019, to assess their impact on indoor air concentrations of PCE and TCE. Exhibit 1. Building 6 Indoor Background Sources The positive identification of the PCE and TCE background sources was initially conducted on January 24, 2019 using the HAPSITE in “qualitative” mode (survey mode). Suspect background sources 2019 Indoor Air Data Summary Report 3-2 BI0619191121SLC were screened by placing the HAPSITE sample probe near the top of the product container (in this case the tops of the aerosol canisters) while the instrument collects the sample. No product is dispensed during this screening process. The survey analysis provides a “qualitative” response based on the absence or presence of specific ions associated with the compound of interest (PCE and TCE). In survey mode, if PCE and/or TCE are present in a product it is indicated by the qualitative response (i.e., absent or present) but not a quantitative result (i.e., actual concentration). Exhibit 2 presents the survey mode qualitative result (note response at 1 minute and 30 seconds) of the one of the seven canisters “Open & Shut” product that labeled PCE as an ingredient shown in Exhibit 1. The color-coded lines in Exhibit 2 represent the magnitude at which a compound-specific ion is present. Specific, the red and green lines of the lower plot of Exhibit 2 represent ions 164 and 166, which are the primary and secondary PCE ions, respectively. The black and blue lines represent ions 131 and 132, the primary and secondary TCE ions, respectively. The red-vertical lines of the Exhibit 2 upper plot indicate a high quantity of ions survey ions (i.e., high concentration of PCE and TCE). Exhibit 2. HAPSITE Survey Mode Response of “Open & Shut” Product Follow-up indoor air sampling within the southern region of Building 6 was conducted on January 30, 2019, to assess whether the removal of the multiple indoor background sources of PCE and TCE would reduce indoor air concentrations of these VOCs. Indoor air concentration of PCE in the Electrician Shop went from 915.7 µg/m3 on January 24 to 25.5 µg/m3 on January 30, a 97-percent reduction (Table 2). Indoor air concentration of TCE at this same location went from 7.1 µg/m3 to 2.5 µg/m3, a 64-percent reduction (Table 2). Indoor air concentrations of PCE and TCE measured on January 30, 2019, were below the RBSL, indicating the indoor background sources were the primary source of PCE and TCE in indoor air. No indoor air RBSLs or RALs were exceeded following the removal of the indoor background sources, thus no fixed-lab samples (that is, 24-hour summa canister samples for EPA Method TO-15 analysis) were required (EA, 2017). On January 30, 2019, quantitative samples of the background products in Exhibit 2 were collected to corroborate the survey mode results of January 24, 2019, which indicated the presence of PCE and TCE in these products. Measured PCE concentrations from these products ranged from 2.0 to 9,357.7 µg/m3 and the measured TCE concentrations ranged from 2.16 to 1441.3 µg/m3 (Table 2), confirming that these products did contain PCE and TCE. Outdoor air samples were also analyzed on January 24 and 30, 2019, to assess whether VOCs in outdoor air might impact indoor air. As shown in Table 2, PCE was detected in the first two outdoor 2019 Indoor Air Data Summary Report BI0619191121SLC 3-3 samples of January 24 and not the third. These samples were collected from the same location. The two detections are likely due to PCE carryover in the instrument following the screening of the indoor background sources with high concentrations of PCE. Carryover is common if measured concentrations are high enough, as was the case during the screening of the background products. This conclusion is supported by non-detect result of the third outdoor sample. 3.1.2 Pressure Cycling The Operations Supervisor Office was selected as the compartment within Building 6 to undergo pressure cycling due to its proximity to the exterior soil gas sample locations with elevated PCE concentrations and since it is an occupied office. Pressure cycling was conducted to assess whether a complete VI pathway is present within a building by inducing negative and positive pressure differentials within the selected compartment while measuring indoor air concentrations of target analytes. Building 6 pressure cycling was initially attempted on March 20, 2019 but was not completed because of HAPSITE issues. A second pressure cycling event was conducted on March 28, 2019, and two (-5 and -10 Pascals [Pa]) of the three targeted differential pressures (-5, -10, and 5 Pa) were achieved during this pressure-cycling event. The positive pressure step was not completed because of a HAPSITE issue. Approximately 2.5 air volumes were exchanged during the -5 and -10 Pa pressure steps. Following the second pressure cycling event, it was confirmed that the combined electrical draw of the blower door (used to induce the negative and positive differential) and the HAPSITE caused the HAPSITE to not recognize the external power source used to power the HAPSITE. The baseline indoor air concentration of PCE measured within the Operations Supervisor Office before initiating pressure cycling was 1.15 µg/m3. Indoor air concentrations of PCE decreased to non-detect during both the -5 and -10 Pascal pressure steps. Therefore, a positive pressure step was not essential because of the lack of evidence supporting the presence of a complete VI pathway. No target analytes exceeded indoor air RBSLs or RALs within the breathing zone during pressure cycling. No indoor air RBSLs or RALs were exceeded during pressure cycling, thus no fixed-lab samples (that is, 24-hour summa canister samples for EPA Method TO-15 analysis) were required (EA, 2017). 3.2 Building 7 3.2.1 Indoor Air Monitoring The indoor air monitoring portion of the VI investigation at Building 7 was conducted on January 25, 2019. Building 7 is a two-story building (ground level and partial basement). Figure 3 presents the sample locations within Building 7. Table 3 presents the Building 7 indoor air HAPSITE results. No indoor air target analytes exceeded project screening levels or RALs during the January 25, 2019 indoor air monitoring. PCE was the only indoor air target analyte detected. Indoor air concentrations of PCE ranged from non-detect to 4.76 µg/m3 (Table 3 and Figure 3 [location identification B7-IA-012]). 3.2.2 Pressure Cycling Room 1B01A was selected as the compartment within Building 7 to undergo pressure cycling. This room was selected because of its proximity to the exterior area with known elevated concentrations of PCE in soil gas (Figure 3). Pressure cycling is conducted to assess whether a complete VI pathway is present within a building by inducing negative and positive pressure differentials within the selected compartment while measuring indoor air concentrations of target analytes. Three targeted differential pressures (-5, -10, and 5 Pa) were achieved during pressure cycling. Approximately 2.5 air volumes of the pressure cycle compartment were exchanged during each pressure step. No target analytes exceeded indoor air RBSLs or RALs during pressure cycling. No indoor air samples were collected for EPA Method TO-15 analysis. 2019 Indoor Air Data Summary Report 3-4 BI0619191121SLC 3.3 Building 13 3.3.1 Indoor Air Monitoring The indoor air monitoring portion of the VI investigation of Building 13 was conducted on February 7, 2019. No indoor background sources were identified within the building. Additionally, no indoor air target analytes were detected within Building 13. Figure 4 presents the indoor air sample locations within Building 13. Table 4 presents the indoor air field-screening HAPSITE results. No indoor air RBSLs or RALs were exceeded during indoor air monitoring, thus no fixed-lab samples (that is, 24-hour summa canister samples for EPA Method TO-15 analysis) were required (EA, 2017). 3.3.2 Pressure Cycling Based on discussions with VHA and USACE and to accommodate the building occupants, no pressure cycling was required at Building 13. 3.4 Building 20 3.4.1 Indoor Air Monitoring The indoor air monitoring portion of the VI investigation of Building 20 was conducted on February 7, 2019. No indoor background sources were identified within the building. Additionally, no indoor air target analytes were detected within Building 20. Figure 5 presents the indoor air sample locations within Building 20. Table 5 presents the indoor air field-screening HAPSITE results. No indoor air RBSLs or RALs were exceeded during indoor air monitoring, thus no fixed-lab samples (that is, 24-hour summa canister samples for EPA Method TO-15 analysis) were required (EA, 2017). 3.4.2 Pressure Cycling Based on discussions with VHA and USACE and to accommodate the building occupants, no pressure cycling was required at Building 20. 2019 Indoor Air Data Summary Report BI0619191121SLC 4-1 4. Conclusion In the case of Building 6, no indoor air target analytes exceeded their respective RBSLs once known indoor background sources of PCE were removed (Table 2). The VI investigations conducted at Buildings 7, 13, and 20 indicated that indoor air target analyte concentrations within each building did not exceed RBSLs (Tables 3 through 5, respectively). These results indicated that under current building conditions, there is not likely a complete and significant VI pathway into any of these buildings. 2019 Indoor Air Data Summary Report BI0619191121SLC 5-1 5.

Introduction This Spring 2019 Data Summary Report (DSR) discusses March 2019 soil gas sampling, March-April 2019 groundwater and surface water sampling, monitoring well maintenance, and transducer data collection at Operable Unit 2 (OU-2) for the 700 South 1600 East Tetrachloroethene (PCE) Plume Superfund Site (site) in Salt Lake City, Utah. OU-2 includes PCE-contaminated groundwater extending downgradient from the area near the Veterans Health Administration (VHA) Medical Center into the Accelerated Operable Unit 1 (AOU-1) area. The AOU-1 area is generally located southwest of Mount Olivet Cemetery and is defined as the area where PCE-contaminated shallow groundwater (within 50 feet of the ground surface) and springs may result in potential risk from vapor intrusion (VI) into indoor air (EA, 2019) (Figure 1). Data quality objectives (DQOs) for the remedial investigation (RI) at OU-2 are described in detail in the RI work plan (RIWP) for the OU-2 Remedial Investigation (CH2M, 2018) and are summarized as follows: 1) Determine the source of the PCE plume identified by the U.S. Environmental Protection Agency (EPA) monitoring wells installed in 1998 and determine if there is sufficient mass of PCE in the vadose zone to act as an ongoing source of PCE in groundwater 2) Determine the lateral, vertical, and downgradient extent of the PCE plume identified by the 1998 EPA monitoring wells 3) Determine if PCE and daughter products measured in the East Side Springs (ESS) area (defined as the area where PCE and/or trichloroethene [TCE]-contaminated groundwater is present within 50 feet of the surface or discharges as seeps or springs) are related to the PCE plume identified by the 1998 EPA monitoring wells 4) Determine what hydrogeological features control PCE fate and transport in OU-2 groundwater. If it is determined that the PCE plume extends into the AOU-1 area, determine what factors control the plume in the fault zone and if the entire plume discharges to the hillside or if some component of groundwater contamination continues further to the west 5) Determine the nature of the hydraulic connection between the PCE plume and production wells (SLC-18, University of Utah wells, and Mount Olivet Well) (Figure 1) 6) Determine if there are additional human and/or ecological exposure pathways in addition to VI in AOU-1, drinking water wells, and potential source-area soil and soil gas 7) Collect data to support possible remedial technologies including monitored natural attenuation, hydraulic containment, and bioremediation. Determine what natural attenuation processes are operating and estimate the rate of degradation of PCE and PCE daughter products Field work discussed in this report specifically addresses the first phase (Phase I) of the RI. The following Phase I activities were conducted in 2019 and are discussed in this report:  Installation and sampling of 14 sub-slab vapor pins at VHA Buildings 6 and 7  Monitoring well maintenance activities including completion replacement, monitoring well re-development, and transducer and pump installation  March-April 2019 groundwater sampling  March 2019 surface water sampling  March and June 2019 transducer data collection The field activities described above are discussed in the following sections. Daily field activities were recorded in daily reports and field notebooks included in Appendices A and B, respectively. All appendices are provided in the electronic version of this report. Additional field work conducted in 2019 is discussed in the 2019 Indoor Air Data Summary Report (Jacobs, 2019d) and the 2019 Expanded Source Area Investigation Data Summary Report (to be submitted later in 2019). Spring 2019 OU-2 Data Summary Report AX0924191107SLC 2-1 2. March 2019 Soil Gas Sampling A sub-slab soil gas investigation was conducted within Buildings 6 and 7 of the VHA Campus during March 2019 to evaluate sub-slab soil gas concentrations of cis-1,2-dichlorethene (cis-1,2-DCE), TCE, and PCE. This investigation was conducted as a follow-up to two previous investigations:  December 2018 exterior soil gas sampling, during which PCE concentrations in soil gas measured adjacent to Buildings 6 and 7 exceeded the EPA industrial soil gas vapor intrusion screening level (VISLsg) of 600 micrograms per cubic meter (µg/m3) (Jacobs, 2019d). One soil gas sample location also exceeded the industrial VISLsg for the PCE daughter product TCE of 29.3 µg/m3 during the December 2018 sampling event (Jacobs, 2019d). The results of the December 2018 exterior soil gas sampling are provided in the 2018 OU-2 Data Summary Report (Jacobs, 2019b).  An indoor air investigation within Buildings 6 and 7 was conducted from January – March 2019. The indoor air investigation is discussed separately in the 2019 Indoor Air Data Summary Report (Jacobs, 2019d). The March 2019 sub-slab soil gas investigation included the installation and sampling of 14 sub-slab soil gas probes (VP-01 through VP-14) (Figure 2). Sub-slab soil gas probe installation and sampling was conducted per the Field Instructions Summary for Vapor Intrusion Investigation (Jacobs, 2019a). Sub-slab soil gas probes were installed by drilling a 1.5 -inch-diameter hole in the slab, which was countersunk to a depth of 1.5 inches, and a ⅝-inch hole in the center of the 1.5-inch countersunk hole that penetrated the slab. A Cox and Colvin Vapor PinTM (vapor pin) was then installed within the ⅝-inch hole. Each sub-slab vapor pin was leak tested during purging and sampling to confirm that no ambient air could be drawn into the sample during sample collection. Prior to sample collection, three “dead space” (that is, area within the vapor pin port and the ⅝-inch hole below vapor pin) volumes were purged to ensure that the soil gas sample collected was representative of sub-slab soil gas and not influenced by ambient air that may have entered the vapor pin during sample collection setup. Soil gas samples were collected in 1-liter Tedlar bags and then screened in the field by a portable gas chromatography/mass spectrometer (Inficon HAPSITE [HAPSITE]) for cis-1,2-DCE, TCE, and PCE immediately after collection. Additionally, sub-slab soil gas samples were collected in 1-liter SUMMA canisters over a 5-minute period from each location and submitted for laboratory analysis (EPA Method TO-15 full scan). A duplicate SUMMA canister was also collected at 1 in 10 sample locations. Soil gas analytical data are presented in Table 1 and on Figure 2. Soil gas sample logs, photo logs, and HAPSITE logs and data files are included in Appendix C. Validated TO-15 soil gas data are included in Appendix D. The Quality Control Summary Report for the validation of the March 2019 TO-15 data is attached as Appendix E. 2.1 Utility Clearance and Permitting Utility clearance was performed by Ground Penetrating Radar Systems, LLC on the VHA campus. For each sub-slab soil gas probe, all utilities and rebar grids within the slab in a 2-foot by 2-foot square were demarcated prior to drilling. Utility location identified a thicker than anticipated slab thickness at the originally proposed location for vapor pin VP-08; as a result, this location was relocated approximately 25 feet southeast of its originally proposed location. 2.2 Soil Gas Analytical Results Exceedances of the PCE Industrial VISLsg occurred at one basement sample location at Building 6 (VP-04) and one ground level location at Building 7 (VP-11) (Table 1; Figure 2). Soil gas samples exceeded the TCE Industrial VISLsg at two basement locations in Building 6 (VP-04 and VP-14 [SUMMA samples only, concentration estimated]). Sub-slab soil gas PCE and TCE VISLsg exceedance locations are proximal to the December 2018 exceedance locations (that is, clustered in the area between Buildings 6 and 7) (Figure 2). Spring 2019 OU-2 Data Summary Report AX0924191107SLC 3-1 3. Monitoring Well Completion Replacement Monitoring well vaults and surface completions were replaced for EPA wells EPA-MW -01 shallow/deep (S/D) and EPA-MW -02. The flush-mount vault in EPA-MW -02 was noted as damaged during sampling in November 2018 and the flush-mount vault was found missing and the vault broken in EPA-MW -01 while surveying wells in February 2019. Although the exact reason for the damage could not be determined, the concrete pad around each vault sloped up with the top of the metal vault protruding slightly above the concrete pad. It is possible that snow plows struck and damaged the concrete vaults while clearing the area. EPA-MW -01 and EPA-MW -02 surface completions were replaced in January – February 2019. During Spring 2019 groundwater sampling, water from the large salt pile located adjacent to EPA-MW -02 was observed running over the top of EPA-MW -02 and ponding within the vault. Water with salt crystals was also observed ponding within the vault of EPA-MW-01S/D and water was observed seeping up through cracks in the parking lot near EPA-MW -01S/D. Salt stains were also observed at the seepage cracks in the parking lot. It is likely that water originating from the salt pile adjacent to EPA-MW -02 flowed under the asphalt to EPA-MW -01S/D, infiltrating the vault from the bottom rather than infiltrating from the top of the vault cap due to overland water flow. It is possible that water originating from a large salt pile stored near EPA-MW -02 was present in the subsurface at both well locations during the initial surface completion replacement and compromised the concrete pads, allowing water to infiltrate the vaults below the surface at both locations. To address the presence of surface water in the vaults, the vaults and surface completions were re-installed on May 28 and 29, 2019. Prior to the surface completion replacement, the pumps and pressure transducers were temporarily removed from the wells. The pumps and pressure transducers were re-installed in EPA-MW-01S, EPA-MW -01D, and EPA-MW -02 on June 4, 2019. Monitoring well completion replacement is discussed in further detail in Appendix F. Spring 2019 OU-2 Data Summary Report AX0924191107SLC 4-1 4. Groundwater and Surface Water Sampling Groundwater sampling activities included monitoring well development, transducer data collection, well gauging, and March - April 2019 groundwater sampling. Groundwater sample locations and the approximate extent of PCE in groundwater are shown on Figure 3. Spring 2019 PCE and TCE concentrations are shown on Figures 4A and 4B. Surface water sampling was conducted in March 2019. Surface water sampling locations and PCE and TCE concentrations are shown on Figure 5. Validated data are included in Appendix D. The Quality Control Summary Reports for the validation of the March – April 2019 groundwater and surface water data are attached as Appendix G. Groundwater and surface water sampling logs are included in Appendices H and I, respectively. Investigation-derived waste (IDW ) manifests are included in Appendix J. 4.1 Monitoring Well Development MW -08C was developed using the manufacturer recommended air-lift development method for the zone isolation sampling technology pump in February 2019. This method was selected due to initial high turbidity measurements of water collected from the MW-08C interval. EPA-MW -01D and EPA-MW -02 were redeveloped in April 2019 after surface water was observed infiltrating the wells during spring 2019 groundwater sampling. Monitoring well development volumes and field parameters are included in Table 2. Monitoring well development logs are included in Appendix K. 4.2 Transducer Data Collection Transducer data were collected in March and June 2019. Data could not be retrieved from EPA-MW -01S during the June 2019 data collection event. The EPA-MW -01S transducer had been installed several years prior and, in consultation with the manufacturer, was determined to be non-functional and at the end of its expected lifetime. The EPA-MW -01S transducer was shipped to the manufacturer for data retrieval, and the recovered data were provided by the manufacturer on July 30, 2019. A replacement transducer was installed in EPA-MW -01S on July 11, 2019. Transducer depths and download dates are included in Table 3. Transducer logs and field book pages are included in Appendix L. Transducer data are included in an electronic data deliverable attached to this report. 4.3 Monitoring Well Gauging All monitoring wells were gauged on March 5 and March 6, 2019. Depth to water and groundwater elevations are included in Table 4. Groundwater potentiometric contours were drawn using the approach described in the Conceptual Site Model Addendum (Jacobs, 2019c) and are shown on Figure 1. 4.4 Groundwater Sampling Groundwater samples and field parameters were collected from all monitoring wells in March and April 2019. Groundwater sampling field parameters are summarized in Table 5. Three well intervals (MW -03R-D, MW -08C, and MW -13S) had negative oxidation reduction potential values (-70.7 to -34.2 millivolts) and low dissolved oxygen values relative to other wells (1.2 – 2.2 milligrams per liter [mg/L]), indicating possible reducing conditions present at these locations. Groundwater sampling analytical results are discussed in further detail in the following subsections. Note that no pesticides were detected in groundwater during the spring 2019 sampling event. Groundwater and surface water sampling analytes are listed in Table 6. Spring 2019 OU-2 Data Summary Report 4-2 AX0924191107SLC 4.4.1 Volatile Organic Compounds Detected volatile organic compounds (VOCs) in groundwater are tabulated in Table 7. PCE and TCE concentrations in groundwater are also summarized on Figures 4A and 4B. The following locations had PCE concentrations above the maximum contaminant level (MCL) of 5 micrograms per liter (µg/L) (MCLs and risk-based screening levels are included in the RIWP [CH2M, 2018]): Location ID Sample Date PCE Concentration (µg/L) EPA-MW -01S 3/18/2019 200 EPA-MW -02 4/9/2019 180 MW -03R-A 3/25/2019 30 MW -03R-B 3/25/2019 230 MW -03R-C 3/27/2019 6.3 EPA-MW -04 3/19/2019 67 MW -08A 3/21/2019 67 MW -13D 3/7/2019 60 MW -13S 3/6/2019 18 MW -14D 3/7/2019 36 MW -16S 3/14/2019 27 MW -18 3/4/2019 83 MW -19 3/4/2019 66 MW -20D 3/5/2019 12 Overall, PCE concentrations remained relatively steady between the December 2018 and March-April 2019 sample events (Jacobs, 2019b). All sample results for TCE were below the MCL of 5 µg/L (Table 7). 4.4.2 Semivolatile Organic Compounds Detected semivolatile organic compounds (SVOCs) are tabulated in Table 8. The only detected SVOC was bis (2-ethylhexyl) phthalate in EPA-MW -02 (4.2 J µg/L, where J indicates an approximate result between the method detection limit and the reporting limit) and EPA-MW -06 (150 µg/L; above the MCL of 6 µg/L) (Table 8; CH2M, 2018). Bis (2-ethylhexyl) phthalate was not detected in EPA-MW -02 or EPA-MW -06 during the fall or winter 2018 sample events (Jacobs, 2019b). 4.4.3 1,4-Dioxane 1,4-dioxane was detected below the analytical method reporting limit in MW -14S and MW -15S during the March – April 2019 sample event (Table 9). Neither detection was above the risk-based water screening level of 0.46 µg/L. No MCL is established for this compound (CH2M, 2018). Spring 2019 OU-2 Data Summary Report AX0924191107SLC 4-3 4.4.4 Metals Groundwater metals concentrations are tabulated in Table 10. The following compounds were measured at concentrations greater than the MCL or risk-based screening levels outlined in the RIWP during the spring 2019 sampling event (CH2M, 2018):  Cobalt: 0.6 µg/L risk-based screening level – Multiple detections; concentrations above screening level ranged from 0.654 J µg/L in EPA-MW- 02 to 2.44 µg/L in MW-15S  Manganese: 43 µg/L risk-based screening level – Multiple detections; concentrations above screening level ranged from 58.4 µg/L in MW-17D to 865 µg/L in MW-08C  Nickel: 39 µg/L risk-based screening level – MW-13S: 176 µg/L MW-03R-D, MW-08C, and MW-13S, had the highest manganese concentrations of all monitoring well locations (Table 10). Iron concentrations in these locations were also higher than the majority of monitoring well locations, ranging from 396 µg/L (MW-08C) to 1,190 µg/L (MW-03R-D). The combination of high concentrations of iron and manganese relative to other locations, low dissolved oxygen concentrations, and negative oxidation-reduction values is indicative that reducing conditions may be present in these monitoring well intervals. Similar conditions were also present in MW-13S during the fall and winter 2018 sampling events. Note that MW-03R-D and MW-08C were sampled for the first time in spring 2019 as the pumps for these intervals were not received from the manufacturer until late 2018 and the well intervals were developed after the December 2018 sampling round was completed. 4.4.5 General Chemistry General chemistry analytical results are tabulated in Table 11. General chemistry parameters include alkalinity, chloride, nitrate and nitrite as nitrogen (N), sulfate, total dissolved solids (TDS), and total organic carbon (TOC). The range of concentrations in general chemistry parameters measured during the spring 2019 sampling event are as follows:  Alkalinity: 232 mg/L (MW-08C) to 384 mg/L (MW-14S)  Chloride: 53.7 mg/L (MW-08C) to 1,280 mg/L (MW-01D)  Nitrate and nitrogen as N: 0.35 mg/L (MW-13S) to 5.8 mg/L (MW-21)  Sulfate: 69 mg/L (MW-21) to 219 mg/L (MW-03R-D)  TDS: 570 mg/L (MW-16D) to 2,730 mg/L (EPA-MW-01D)  TOC: 0.466 mg/L (MW-12D) to 9.06 mg/L (MW-03R-D) Low nitrate levels relative to the majority of the wells were present in MW-03R-D (0.878 mg/L), MW-08C (1.29 mg/L), and MW-13S (0.351 mg/L). Low nitrate levels are a further indication of possible reducing conditions at these locations. 4.5 Surface Water Sampling Surface water sampling locations are summarized in Table 12 and shown with PCE and TCE concentrations on Figure 5. All surface water sampling locations identified in the 2018 DSR were sampled in spring 2019 (Jacobs, 2019b). Although these locations are all described as surface water per the RIWP, two locations may be more indicative of shallow groundwater. SW-06 is a decorative well with a total well depth below the water table at its location, and SW-35 is a seep that surfaces from below ground level. Surface water sampling field parameters are summarized in Table 13. Surface water sampling analytical results are discussed in further detail in the following subsection. Note that no detections were observed for 1,4-dioxane or pesticides in surface water samples. Surface water sampling analytes are summarized in Table 6. Spring 2019 OU-2 Data Summary Report 4-4 AX0924191107SLC 4.5.1 Volatile Organic Compounds Detected VOC concentrations in surface water are summarized in Table 14. PCE and TCE concentrations in surface water are also summarized on Figure 5. TCE did not exceed the MCL of 5 µg/L at any surface water sampling location. The following locations had PCE concentrations above the MCL of 5 µg/L: Location ID Sample Date PCE Concentration (µg/L) SW-06 3/25/2019 48 SW-34 3/27/2019 5.1 SW-35 3/27/2019 8.6 SW-39 3/25/2019 19 SW-53 3/25/2019 28 4.5.2 Semivolatile Organic Compounds Detected SVOCs are tabulated in Table 15. The only detected SVOC was bis (2-ethylhexyl) phthalate in SW-34 (3.6 J µg/L) and SW-35 (4.4 J µg/L). All detections were below the MCL of 6 µg/L (CH2M, 2018). 4.5.3 Metals Surface water metals concentrations are tabulated in Table 16. Only one detection exceeded the MCL or risk-based screening level outlined in the RIWP (CH2M, 2018). Arsenic measured at 11.1 µg/L at SW-53 in spring 2019, exceeding the MCL of 10 µg/L. Arsenic exceedances were also measured at this location in 2018 (Jacobs, 2019b). 4.5.4 General Chemistry Surface water general chemistry analytical results are tabulated in Table 17. The range of concentrations in general chemistry parameters measured in spring 2019 are as follows:  Alkalinity: 241 mg/L (SW-48) to 332 mg/L (SW-53)  Chloride: 74.1 mg/L (SW-47) to 340 mg/L (SW-39)  Nitrate and nitrogen as N: 0.653 J mg/L (SW-51) to 4.45 J mg/L (SW-39)  Sulfate: 104 mg/L (SW-35) to 141 mg/L (SW-47 and SW-51)  TDS: 520 mg/L (SW-47) to 1,040 mg/L (SW-53)  TOC: 0.506 J mg/L (SW-48) to 2.09 mg/L (SW-35) 4.6 Groundwater and Surface Water Stable Isotopes Groundwater and surface water samples were submitted to the University of Utah’s Stable Isotope Ratio Facility for Environmental Research (SIRFER) laboratory for stable isotope analysis. As described in the RIWP and discussed further in the Conceptual Site Model Addendum, stable isotope data may offer insight into mixing relationships between different groundwater and surface waters at the site (CH2M, 2018; Jacobs, 2019c). Stable isotope data are tabulated in Table 18 and shown on Figure 6. The SIRFER laboratory report is included in Appendix M. Spring 2019 OU-2 Data Summary Report AX0924191107SLC 5-1 5. Summary A summary of how the spring 2019 field work has advanced the stated DQOs is presented in the following subsections. Additional DQOs not included in the following sections (for example, hydraulic connection to production wells, exposure pathways, and remedial technologies) were not directly addressed by the field work discussed in this report. 5.1 PCE Plume Source Investigation Exceedances of the PCE Industrial VISLsg and TCE Industrial VISLsg were measured in March 2019 sub-slab soil gas samples collected in Buildings 6 and 7 (Table 1; Figure 2). These results are consistent with the 2018 soil gas investigation, which identified the Building 6 – 7 area on the VHA Campus as a PCE source area. The March 2019 sub-slab soil gas investigation improved the spatial resolution of soil gas PCE concentrations in the Building 6 – 7 area and informed the location of additional sub-slab soil gas probes for the expanded source area investigation in summer 2019. 5.2 Plume Nature and Extent The approximate extent of PCE in groundwater derived from spring 2019 groundwater sample concentrations is shown on Figure 3. The 2019 extent of PCE is generally consistent with the extent derived from December 2018 PCE concentrations (Jacobs, 2019b; Figure 3). The concentration of PCE in MW -15S increased from non-detect in 2018 to 3.3 µg/L in spring 2019, extending the toe of the approximate extent of PCE in groundwater further to the southwest in the AOU-1 area in 2019 (Jacobs, 2019b; Figure 3). Deep monitoring well intervals MW -03R-D (359-364 feet below ground surface [bgs]) and MW-08C (304-309 feet bgs) were sampled for the first time in spring 2019 and measured below the reporting limit for both PCE and TCE, providing a vertical extent for the PCE plume in these locations (Figure 4A). Deep monitoring well interval EPA-MW -01D (364-404 feet bgs) was also non-detect for PCE and TCE in spring 2019, consistent with 2018 concentrations and providing a vertical boundary to PCE in that location. Shallow monitoring wells MW-21, MW -22, and MW -17S/D measured non-detect or below the MCL for PCE and provide a southern boundary for the approximate extent of PCE in AOU-1 (Figure 4B). Downgradient wells MW -12S/D and MW -15S/D measured below the MCL for PCE and TCE. 5.3 PCE and TCE in East Side Springs Area PCE and TCE were measured in shallow monitoring wells and seeps and springs in the ESS area in 2018 and spring 2019 (Figures 4B and 5). MW -18, located immediately east of the ESS area, had the highest concentration of PCE in both 2018 (96 µg/L in September 2018) and 2019 (83 µg/L). The highest concentration of TCE in spring 2019 was measured in MW -15S (4.2 µg/L). The highest concentration of TCE in 2018 was measured in MW -14S (4.3 µg/L in December 2018); TCE was non-detect at this location in spring 2019 (Figure 4B). PCE measured above the MCL in seep and spring sampling locations SW -06, SW-34, SW -35, SW -39, and SW -53 (Figure 5). The highest concentration of PCE in surface water was measured in SW -06 (48 µg/L). PCE in SW -34 was measured below the MCL in 2018 (2.3 µg/L in October 2018 and 4.9 µg/L in December 2018). SW -53 had the highest concentration of TCE in surface water (2.8 µg/L, below the MCL of 5 µg/L). TCE was also detected in adjacent surface water sampling locations SW -06 (1.2 µg/L) and SW -39 (0.83 J µg/L) (Figure 5). PCE and TCE were non-detect in the northernmost surface water location SW -48 and in all Red Butte Creek sample locations. Spring 2019 OU-2 Data Summary Report 5-2 AX0924191107SLC 5.4 Hydrogeology Groundwater potentiometric contours and flow directions did not significantly change from December 2018 to spring 2019 (Jacobs, 2019b; Figure 1). Shallow groundwater flows to the northwest east of Guardsman Way and to the southwest west of Guardsman Way (Figure 1). Deeper groundwater flows to the southwest overall (Figure 1). An in-depth discussion of the site hydrogeology is included in the Conceptual Site Model Addendum (Jacobs, 2019c). Spring 2019 OU-2 Data Summary Report AX0924191107SLC 6-1 6.

The ground surface elevations for well pairs (for example, MW-12S and MW-12D) are different because the wells are in different adjacent boreholes. c The pressure gauge on MW-14D had a reading of 1.8 pounds per square inch on 3/5/2019, which equates to 4.2 feet of head. This was added to the surveyed elevation of the pressure gauge (4415.80 ft amsl) to generate an estimated water level.

Introduction Soil gas probes and vapor pins were installed on the Veterans Health Administration (VHA) Campus and Sunnyside Park in December 2018 and March 2019 as part of the source area investigation for Operable Unit (OU) 2 for the 700 South 1600 East Tetrachloroethene (PCE) Plume Superfund Site (site) in Salt Lake City, Utah. These activities are discussed in further detail in the 2018 OU-2 Data Summary Report (DSR) and the Spring 2019 OU-2 DSR (Jacobs, 2019a, 2019c). This 2019 Expanded Source Area Investigation DSR is a follow-up to the previous soil gas investigations on the VHA Campus and Sunnyside Park and discusses the installation of new soil gas probes and vapor pins on the VHA Campus in June and July 2019 and the sampling of new and existing soil gas probes and vapor pins in July 2019. Two primary areas have been identified as potential sources of PCE release as a result of previous soil gas investigations: the Buildings 6 and 7 area on the VHA campus and the sewer line defect adjacent to Manhole 22658 in Sunnyside Park (Figure 1; Jacobs, 2019a). As a follow-up to the December 2018 and March 2019 investigations and a historical records review of VHA Buildings 6 and 7, additional soil gas probes and vapor pins were proposed to be installed in the Buildings 6 and 7 area to investigate specific potential release points and to further delineate PCE concentrations in this area (Jacobs, 2018, 2019c, 2019d). Soil gas probe and vapor pin installation and sampling were conducted in June and July 2019 as described in detail in the following sections. Daily field activities were recorded in daily reports and field notebooks included in Appendices A and B, respectively. 2. Probe Installation A total of 11 additional soil gas probes and eight additional vapor pins were installed according to the methods described in Modification #1 to OU-2 Remedial Investigation Work Plan (Soil Gas Sampling Proposed in Section 5 of RIWP), 700 South 1600 East PCE Plume, Salt Lake City, Utah (Jacobs, 2018). The selection and installation of soil gas probe and vapor pin locations are described in the following sections. 2.1 Previous Investigations and Historical Records Review The expanded source area investigation is a follow-up to three previous investigations: • December 2018 exterior soil gas sampling, in which exceedances of the PCE Industrial Soil Gas Vapor Intrusion Screening Level (VISLsg) of 600 micrograms per cubic meter (µg/m3) occurred at 4 soil gas probe locations in the VHA Buildings 6 and 7 area and two probe locations adjacent to Manhole MH-22658 in Sunnyside Park (Jacobs, 2019b). One soil gas sample location in the VHA Buildings 6 and 7 area also exceeded the industrial VISLsg (29.3 µg/m3) for the PCE daughter product trichloroethene (TCE) during the December 2018 sampling event (Jacobs, 2019a). • January – March 2019 indoor air investigation conducted in response to VISLsg exceedances in the VHA Buildings 6 and 7 area. The results of this investigation are discussed in the 2019 Indoor Air DSR (Jacobs, 2019b). • March 2019 interior sub-slab soil gas sampling in which a total of 14 vapor pins were installed in Buildings 6 and 7. Exceedances of the PCE Industrial VISLsg occurred at one basement sample location at Building 6 and one ground level location at Building 7. Soil gas samples also exceeded the TCE Industrial VISLsg at two basement locations in Building 6 (Jacobs, 2019c). As a result of these investigations, the VHA Buildings 6 and 7 area and a sewer line defect adjacent to Manhole MH-22658 were identified as potential PCE release points. A historical records review was subsequently conducted for Buildings 6 and 7 to identify specific locations where PCE may have been released to surface soil or subsurface soil during the dry cleaner operation in the late 1970s and early 1980s (Jacobs, 2019d). Additional soil gas sample locations were proposed as part of the expanded source area investigation to further delineate areas where PCE concentrations exceeded the Industrial 2019 Expanded Source Area Investigation Data Summary Report 2 AX1028191153SLC VISLsg during previous sample events and to address the following areas identified as potential PCE release points in the historical records review: • Adjacent to the back-door of the Building 7 dry-cleaning facility according to the 1981 building footprint • Downslope (west) of Building 7 to investigate possible release through sanitary sewer piping and a scale pit indicated in Building 7 historical drawings • Adjacent to a rock sump / dry well at the south/southeast end of Building 7 • Adjacent to a rock sump or underground storage tank (UST) on the west side of Building 7 Soil gas probe and vapor pin installation are discussed in detail in the following subsections. 2.2 Utility Clearance and Permitting Utility clearance was performed by Ground Penetrating Radar Systems, LLC for all new soil gas probe and vapor pin locations on the VHA campus. All utilities were demarcated before excavation. Photos of all sample locations with utility markings are included in Appendix A. Utilities in the VHA Buildings 6 and 7 area are presented on Figure 3A with the soil gas and vapor pin sampling locations. All work on the VHA campus was performed in compliance with the VHA stormwater pollution prevention plan (SWPPP). SWPPP inspections and excavation checklists are included in Appendices C-1 and C-2, respectively. 2.3 Soil Gas Probe Installation Soil gas probes were constructed on the VHA campus by hand augering per the methods outlined in Modification #1 to the Remedial Investigation Work Plan (Jacobs, 2018). Soil gas probe locations and depths are included in Table 1. An overview of all soil gas probe sample locations is shown on Figure 2. Soil samples were collected at the base of each hand-augered borehole and submitted for SW-8260C analysis (Table 2). The following soil gas probes were installed in June and July 2019 (Figure 3A): • SG-45 and SG-46 were installed on the northeast side of Building 7. These locations were selected to refine the delineation of the eastern side of the suspected PCE source area and were located as close as possible to the historical back-door of the Building 7 dry-cleaning facility. • SG-48 and SG-49 were installed on the northwest side of Buildings 6 and 7 to refine delineation of the northern extent of the suspected PCE source area. • SG-50 and SG-51 were installed in the alley between Buildings 6 and 7 to investigate the possibility that PCE was released beneath Building 7 or in the area between Buildings 6 and 7 where a historical storm sewer manhole was also identified. These locations also serve to refine the delineation of PCE in this area and to supplement data from existing sample locations SG-03, SG-04, VP-09, and VP-11. An additional soil gas location, SG-60, was installed adjacent to SG-51 to sample above the gravelly clay layer observed from 5.0 to 9.3 feet below ground surface (bgs) at that location. • SG-52 was installed at the southeast end of Building 7 to assess whether a historical rock sump / dry well located in this vicinity may have been a historical PCE release point. • SG-53 and SG-54 were installed on the southeast side of Building 6 to further delineate the suspected PCE source area in this area. • SG-55 was installed at the southwest side of Building 6 to further delineate the suspected PCE source area in this area. Two additional locations, SG-47 and SG-56, were originally proposed in this area, however a water main identified during utility location prevented the installation of additional points in this area. Soil gas probes in the Buildings 6 and 7 area are shown on Figure 3A. 2019 Expanded Source Area Investigation Data Summary Report AX1028191153SLC 3 2.4 VHA Buildings 6 and 7 Vapor Pin Installation Fourteen sub-slab vapor pins were installed in March 2019 and documented in the Spring 2019 DSR (Jacobs, 2019c). Eight additional vapor pins were subsequently proposed to improve the spatial resolution of soil gas PCE concentrations in Buildings 6 and 7 (Jacobs, 2019d). The following vapor pin locations were installed in June and July 2019 (Figure 3A): • VP-15, VP-16, and VP-17 were installed in the basement of Building 6 to delineate PCE near VP-04. VP-04 was installed in the basement of Building 6 in March 2019 and exceeded the Industrial VISLsg by an order of magnitude during the March 2019 sample event. • VP-18 and VP-19 were installed at the ground level in the northern portion of Building 6 near previously installed vapor pins VP-05 and VP-06. • VP-20 was installed in the ground level in the interior of Building 7. This location was selected based on the location of a historical rock sump potentially located in this area. • VP-21 was installed in a concrete stairwell on the east side of Building 7 to provide additional data near the historical back door of Building 7. • VP-22 was installed in a concrete stairwell on the south side of Building 7 to sample close to a historical rock sump potentially located in this area. The vapor pin locations are described in Table 1 and shown on Figure 3A. 3. Soil Gas and Soil Sampling Results Soil gas samples were collected in 1-liter Tedlar bags using a lung box and screened with a photoionization detector prior to being analyzed by a portable gas chromatography/mass spectrometer (Inficon HAPSITE [HAPSITE]) for PCE, TCE, and cis-1,2-dichloroethene [DCE]). The HAPSITE was calibrated from 0.5 to 100 parts per billion by volume (ppbv) at the start of sample collection and a check standard run at the start and end of each day of sample collection. If the check standard failed (falling outside of a plus or minus 30-percent threshold), the HAPSITE was re-calibrated. Samples were run on the HAPSITE on the day of sample collection at an initial 1:10 dilution. If the initial 1:10 dilution result indicated the PCE concentration of the undiluted sample would exceed the calibration range, a second sample was run at a dilution within the calibration range of 0.5 to 100 ppbv. The total PCE, TCE, and cis-1,2-DCE concentrations were then calculated using the HAPSITE dilution factor. Soil gas samples were run undiluted on the HAPSITE whenever possible. At least one SUMMA canister, for every ten soil gas sample locations, was also collected for laboratory analysis (U.S. Environmental Protection Agency [EPA] Method TO-15 full scan [TO-15]) for confirmation sampling. A summary of all soil gas HAPSITE results, EPA Method TO-15 results, and soil sample PCE and TCE results are included in Table 2. A summary of HAPSITE calibration and check standards during sample collection is included in Table 3. Soil gas sample results are discussed in the following subsections and broken out by sample area. TO-15 results are used for discussion where collected. Cis-1,2-DCE concentrations were non-detect at all sample locations. Soil samples collected from new soil gas sample locations tested non-detect for PCE and TCE (Table 2). A summary of all soil gas sample locations sampled in July 2019 is shown on Figure 2. Buildings 6 and 7 area sample locations are summarized on Figure 3A. Soil gas locations and results are broken out by location on Figures 3B through 6. Soil gas sample logs are included in Appendix D, HAPSITE logs and calibration and data files are included in Appendix E, and validated data are included in Appendix F. The Quality Control Summary Report for the data is included in Appendix G. 2019 Expanded Source Area Investigation Data Summary Report 4 AX1028191153SLC 3.1 VHA Buildings 6 and 7 Area 3.1.1 Building 6 Area Soil Gas Sample Locations Two soil gas probe locations exceeded the PCE Industrial VISLsg (600 µg/m3) in the VHA Building 6 area in July 2019 (Table 2; Figure 3B): • SG-03: 3,800 µg/m3 PCE (HAPSITE result) • SG-13: 1,600 µg/m3 PCE (HAPSITE result) SG-03 is located in the alley between Buildings 6 and 7, northwest of vapor pin VP-15. The July 2019 concentration at this location was an increase from the 2,900 µg/m3 PCE concentration measured in December 2018 (Jacobs, 2019a). SG-13 is located on the east side of Building 6 adjacent to the sewer line. PCE at this location also increased from the December 2018 concentration that measured below the Industrial VISLsg at approximately 550 µg/m3 (HAPSITE result; Jacobs, 2019a). In this and previous DSRs, intermediate PCE concentrations are defined on the figures as concentrations between 10-percent of the screening level and the screening level, or 60 – 600 µg/m3. Soil gas locations SG-14, SG-55, and SG-60 measured in the intermediate range for PCE in the Building 6 area as shown on Figure 3B. TCE was detected in two soil gas sample locations below the Industrial VISLsg in the Building 6 area (Table 2): • SG-60: 20 µg/m3 TCE (HAPSITE result) • SG-51: 1.4 J µg/m3 TCE (TO-15 result) Note that J is a data qualifier that indicates a result below the reporting limit and above the method detection limit. 3.1.2 Building 6 Area Vapor Pin Sample Locations Four Building 6 vapor pins exceeded the PCE Industrial VISLsg in July 2019 (Figure 3B). All exceedances occurred in basement vapor pin locations and Summa samples were collected at each location: • VP-04: 20,000 µg/m3 PCE (TO-15 result) • VP-15: 21,000 µg/m3 PCE (TO-15 result) • VP-16: 3,600 µg/m3 PCE (TO-15 result) • VP-17: 1,400 µg/m3 PCE (TO-15 result) VP-04 was originally installed in March 2019 and exceeded the PCE Industrial VISLsg by more than an order of magnitude during both March and July 2019 events (33,000 µg/m3 TO-15 result in March 2019) (Jacobs, 2019c). VP-15 was installed north of VP-04 in July 2019 and also exceeded the PCE Industrial VISLsg by more than an order of magnitude in July 2019 (Table 2; Figure 3B). Vapor pins VP-16 and VP-17 were installed to the east and south of VP-04, respectively (Figure 3B). Intermediate PCE concentrations were measured in HAPSITE samples collected at four vapor pin locations in the Building 6 area (VP-02, VP-03, VP-05, and VP-14) as shown on Figure 3B. HAPSITE results showed similar exceedances at VP-04, VP-15, VP-16, and VP-17, although significant differences in HAPSITE and TO-15 results were observed at VP-04 and VP-15 (Table 2). Samples with high concentrations of PCE (for example, greater than two-times the screening level) are run at a dilution on the HAPSITE as previously described to prevent exceeding the calibration range and overloading the instrument (Table 2). As a result, while the HAPSITE correctly identifies locations with VISLsg exceedances of PCE, at very high concentrations the results can be considered approximate. 2019 Expanded Source Area Investigation Data Summary Report AX1028191153SLC 5 TCE Industrial VISLsg (29.3 µg/m3) exceedances were measured at two locations in July 2019 where PCE Industrial VISLsg exceedances were also observed (Table 2; Figure 3B): • VP-04: 35 J µg/m3 TCE (TO-15 result) • VP-15: 160 µg/m3 TCE (TO-15 result) 3.1.3 Building 7 Area Soil Gas Sample Locations Six soil gas locations exceeded the PCE Industrial VISLsg in the VHA Building 7 area in July 2019 (Table 2; Figure 3C). All exceedances occurred in locations originally installed in December 2018: • SG-04: 2,400 µg/m3 PCE (HAPSITE result) • SG-05: 4,700 µg/m3 PCE (TO-15 result) • SG-06: 2,000 µg/m3 PCE (HAPSITE result) • SG-08: 1,300 µg/m3 PCE (HAPSITE result) • SG-09: 1,100 µg/m3 PCE (HAPSITE result) • SG-11: 1,200 µg/m3 PCE (HAPSITE result) SG-04, SG-05, and SG-06 are south of Building 7 in the alley between Buildings 6 and 7 and also exceeded the PCE Industrial VISLsg in December 2018 (Jacobs, 2019a). SG-08, SG-09, and SG-11 are southeast of Building 7; PCE concentrations at these locations measured below the Industrial VISLsg in December 2018 (Jacobs, 2019a). Intermediate PCE concentrations were measured at three soil gas sample locations in the Building 7 area (SG-07, SG-12, and SG-50) (Figure 3C). TCE exceeded the Industrial VISLsg at one soil gas location in this area (Table 2; Figure 3C): • SG-06: 30 µg/m3 TCE (HAPSITE result) TCE was detected and measured below the TCE Industrial VISLsg at the following locations in the Building 7 area (Table 2; Figure 3C): • SG-04: 24 µg/m3 TCE (HAPSITE result) • SG-05: 19 µg/m3 TCE (TO-15 result) • SG-50: 2.9 µg/m3 TCE (HAPSITE result) 3.1.4 Building 7 Area Vapor Pin Sample Locations Two vapor pin locations exceeded the PCE Industrial VISLsg in July 2019 (Table 2; Figure 3C): • VP-09: 840 µg/m3 PCE (HAPSITE result) • VP-13: 640 µg/m3 PCE (HAPSITE result) VP-09 is a ground-level vapor pin north of the alley between Buildings 6 and 7 and proximal to soil gas sample locations SG-04 and SG-05 (Figure 3C). This location was originally installed in March 2019 and measured below the Industrial VISLsg for PCE in the March 2019 sample event (Jacobs, 2019c). VP-13 is a basement vapor pin installed in March 2019 and located at the southeast corner of Building 7, directly north of SG-06 (Figure 3C). PCE at this location measured below the Industrial VISLsg in the March 2019 sample event (Jacobs, 2019c). Intermediate PCE concentrations were measured at vapor pin locations VP-08 and VP-11 (Figure 3C). VP-11 is a ground-level vapor pin that exceeded the PCE Industrial VISLsg in March 2019 (Jacobs, 2019c) and decreased to just below the Industrial VISLsg in July 2019 (580 µg/m3). TCE was detected below the TCE Industrial VISLsg at two vapor pin locations in the Building 7 area (Table 2; Figure 3C): • VP-11: 3.4 µg/m3 TCE (TO-15 result) • VP-20: 0.33 J µg/m3 TCE (TO-15 result) 2019 Expanded Source Area Investigation Data Summary Report 6 AX1028191153SLC 3.2 VHA Sewer Line Area PCE did not exceed the Industrial VISLsg at any sample locations in the VHA sewer line area (Table 2; Figure 4). Two locations measured in the intermediate range for PCE concentrations: • SG-17: 190 µg/m3 PCE (HAPSITE result) • SG-19: 110 µg/m3 PCE (HAPSITE result) Both locations with intermediate PCE results are located at the north end of the sewer line area. PCE concentrations increased from December 2018 results for both locations (Jacobs, 2019a). TCE was non-detect for all sample locations in this area (Table 2). 3.3 VHA North Area PCE measured below the Industrial VISLsg at both sample locations in the VHA North Area (Figure 5). PCE concentrations increased at both locations from December 2018 results, although PCE concentrations remained below the intermediate threshold for both sample events (Jacobs, 2019a). TCE was non-detect at both sample locations in this area (Table 2). 3.4 Sunnyside Park Two multi-level soil gas probes were installed in Sunnyside Park during the December 2018 sample event (Jacobs, 2019a). SG-42 is adjacent to Manhole MH-22658 and contains four sample intervals. SG-43 is south of SG-42 and Manhole MH-22658 and includes two sample intervals. One sample interval in SG-42 exceeded the PCE Industrial VISLsg during the July 2019 sample event (Table 2; Figure 6): • SG-42B (12 – 13 feet bgs): 1,100 µg/m3 PCE (HAPSITE result) All other sample intervals in SG-42 and SG-43 measured in the intermediate range for PCE (Table 2; Figure 6): • SG-42A (6 – 7 feet bgs): 330 µg/m3 PCE (HAPSITE result) • SG-42C (16 – 17 feet bgs): 210 µg/m3 PCE (HAPSITE result) • SG-42D (24.8 – 26 feet bgs): 370 µg/m3 PCE (HAPSITE result) • SG-43A (7 – 8 feet bgs): 150 µg/m3 PCE (HAPSITE result) • SG-43B (14.7 – 15.7 feet bgs): 330 µg/m3 PCE (HAPSITE result) Two SG-42 sample intervals, SG-42C and SG-42D, measured above the Industrial VISLsg during December 2018 and decreased to within the intermediate range for PCE concentrations during the July 2019 sample event (Table 2; Jacobs, 2019a). 4. Summary A summary of how the expanded source area investigation has advanced the stated data quality objectives is discussed in the following subsections. 4.1 PCE Plume Source Investigation As previously discussed, the December 2018 soil gas investigation identified two potential PCE source areas: Manhole MH-22658 in Sunnyside Park and the Buildings 6 and 7 area on the VHA campus (Jacobs, 2019a). Additional soil gas probes were installed on the VHA Campus as part of the expanded source area investigation to further delineate the current extent of PCE contamination in soil gas and to target potential specific release points identified in a historical records review in the VHA Buildings 6 and 7 area (Jacobs, 2019d). The results of the June/July 2019 Expanded Source Area Investigation will help focus the remedial investigation and any subsequent source area remedial efforts. Potential areas of PCE release are discussed in the following subsections. 2019 Expanded Source Area Investigation Data Summary Report AX1028191153SLC 7 4.1.1 Manhole MH-22658 in Sunnyside Park Soil gas PCE concentrations measured in July 2019 exceeded the PCE Industrial VISLsg in the 12 to 13-foot sample interval of SG-42, located adjacent to Manhole MH-22658. All other sample intervals in SG-42 and SG-43 measured in the intermediate range for PCE. It is likely that variations in soil gas PCE concentrations from the previous sample event are a result of seasonal variations between the sample events. Overall PCE concentrations measured in July 2019 are consistent with previous sample results, which identified this area as a potential release point for PCE. 4.1.2 Historical Back-door of Building 7 Historical aerial photographs and building photographs showed the location of the historical back door on the northeast side of Building 7 (Jacobs, 2019d). Building additions have subsequently covered this area. Three sample locations were installed in July 2019 to target this location: SG-45, SG-46, and VP-21 (Figure 3A). Soil gas results at these locations measured below the intermediate threshold for PCE concentrations, indicating that this area is not likely a historical release point for PCE. 4.1.3 West Side of Building 7 Historical drawings indicated a rock sump or UST was located on the west side of Building 7 (Jacobs, 2019d). VP-20, SG-48, and SG-49 were installed in this area to investigate this location as a possible PCE release point (Figure 3A). All three locations tested below the intermediate threshold for PCE, indicating this area is not likely a historical release point for PCE. 4.1.4 Southeast of Building 7 Historical drawings for Building 7 indicated the presence of a rock sump / dry well on the south/southeast side of Building 7 (Jacobs, 2019d). Sample locations VP-22 and SG-52 were installed in this area to investigate this location as a possible PCE release point. Both sample locations measured below the intermediate threshold for PCE, indicating this area is not likely a historical release point for PCE (Figure 3A). PCE Industrial VISLsg exceedances were measured in three soil gas probes located further to the southeast of Building 7 and along the sanitary sewer line (SG-08, SG-09, SG-11, and SG-13). PCE concentrations measured in these sample points were significantly lower than PCE in probes on the southwest side of Building 7 in the alley between Buildings 6 and 7, as described in further detail below. 4.1.5 Southwest Side of Building 7, Alley, and Building 6 The highest concentrations of PCE in the Buildings 6 and 7 area were measured in soil gas probes and vapor pins located southwest of Building 7 in the alley between Buildings 6 and 7 and in the basement of Building 6 during the July 2019 sample event (Table 2; Figures 3B and 3C). Soil gas exceedances in this area ranged from over 3 times the PCE Industrial VISLsg in the Buildings 6 and 7 alley sample locations (SG-03, SG-04, SG-05, and SG-06) to over 30 times the PCE Industrial VISLsg in basement sample locations on the northeast side of Building 6 (VP-04, VP-15). The three sample locations where the PCE breakdown product TCE exceeded the Industrial VISLsg were also located in this area (VP-04, VP-15, and SG-06). The cluster of high PCE concentrations in this area likely represents a single zone of PCE soil gas contamination, with variations in PCE concentrations influenced by probe depth, connectivity to the surface, and subsurface geology. Based on the historical records review (Jacobs 2019d), the basement of Building 6 is not considered to be a potential release point for PCE. The significantly higher PCE concentrations measured in Building 6 basement sample locations relative to other sample locations in this area are likely because of the greater depth of the basement vapor pins and more effective trapping of soil gas by the building foundation. The effect of subsurface geology on soil gas concentrations is demonstrated by the difference in PCE concentrations measured in adjacent soil gas probes SG-51 and SG-60. A gravelly clay layer was identified in the borehole of SG-51 from 5.0 to 9.3 feet bgs; the lateral 2019 Expanded Source Area Investigation Data Summary Report 8 AX1028191153SLC extent of this clay layer is not known. PCE measured 10 times higher in SG-60 (screened above the clay layer at this location) relative to SG-51 (screened within the clay layer). PCE Industrial VISLsg exceedances measured southwest of Building 7 and in the alley between Buildings 6 and 7 indicate this is a likely area where one or more releases of PCE occurred. The historical records review identified several possible release points in this area including sewer piping below Building 7, a scale pit indicated in a drawing for Building 7 in the dry cleaning area, and a historical storm sewer manhole located in the alley between Buildings 6 and 7 (Figure 3A; Jacobs, 2019d). 2019 Expanded Source Area Investigation Data Summary Report AX1028191153SLC 9 5.

They completed a pre-task safety plan and loaded up necessary supplies for probe installation. 0930: Jacobs arrived at SG-51 and cored a 6” hole in the asphalt. Larry Kellum was on site. 1030: Began hand augering SG-51. 1105: Hit refusal at 2’ bgs. Moved NE approximately 1-2’ and cored new location. Backfilled the original location with the soil that was removed and replaced the asphalt puck. 1245: Hit refusal on SG-51 at 9’4”. Collected a soil sample and field duplicate at the bottom of the boring. Soil between 5’ and 9’4” was clay with gravel. Discussed presence of clay with Larry Kellum, decided to place probe at bottom of borehole. 1325: Constructed the soil probe on SG-51 as follows: 0-1’ bgs: Play sand 1-8’9” bgs: Bentonite granules 8’9”-9’4”: 8/16 sand 1325: Cleaned up the site and returned to the IDW yard to decontaminate the equipment. 1345: Placed the soil samples in the freezer. 1415: Collected an equipment blank off the auger head. 1424: Returned to SG-53 and SG-54. Marc Yalom had replaced Larry Kellum. Cored a 6” hole for each location. Loose gravel and a void area were found under the concrete pad at SG-54. The loose gravel will make it difficult to hand auger this location without making a much larger void under the concrete as the gravel will slough in. One possible solution would be to get a 6” PVC pipe to use as casing to keep the loose gravel from sloughing in. PAGE 2 OF 2 1530: Cleaned up and left for the IDW yard to decontaminate the equipment.

They completed a pre-task safety plan and loaded up necessary supplies for probe installation. 0900: Jacobs arrived at SG-53. Larry Kellum and Marc Yalom arrived on site. 1125: Hand augered SG-53 to 5’ bgs. Jacobs leaves for Lowes to get casing to case off SG-53 because of the amount of gravel that was sloughing into the boring (7 buckets). 1230: Jeremy Cox called to say to build SG-53 at 5’ to avoid issues with the integrity of the asphalt around the probe, if more gravel sloughs into the boring. 1345: Return to SG-53 after getting supplies at Lowes. 1355: Measured SG-53 at 5’0”. A sample was not collected because the soil is almost completely gravel and there is no material that will fill up an Encore sampler. 1410: Constructed the soil probe on SG-53 as follows: 0-1’ bgs: Play sand 1-4’6” bgs: Bentonite granules 4’6”-5’0”: 8/16 sand 1420: Cleaned up the location and returned to the IDW yard to decontaminate the equipment. 1440: Collected an equipment blank off the auger head. 1450: Returned to SG-54. Installed the casing bought at Lowes to keep the hole from caving. Begin hand augering. 1545: Hand augered SG-54 to 5’1”. The casing kept the hole from caving. Once past the casing at 5’0”, the hole began to cave, and a lot of material was removed (2 buckets) without gaining much depth. It was decided to end the hole. Unable to collect a sample because the material was predominantly coarse-grained material that wouldn’t fit in the sampler. PAGE 2 OF 3 1600: Installed the probe at the bottom of the boring. Constructed the probe at SG-54 as follows: 4’1”-4’6” bgs: Bentonite granules 4’6”-5’1”: 8/16 sand Ran out of bentonite, so ended probe construction for the day.

Results listed below. 1030: Rachel Adams arrived at the IDW yard. 1300: Jeremy Cox (Jacobs) on site. Discussed SG-51 result with VA/USACE. Based SG-03, PCE concentration at SG-51 was anticipated to be higher. It is assumed that the clay layer in which SG-51 is screened is limiting PCE entry into the less permeable clay. It was determined that Jacobs will attempt to reconstruct SG-51, with two soil gas probes (one at 9 ft bgs [current probe depth] and the other over the clay layer at approximately 5 ft bgs) if possible within the existing borehole. This will likely take place Friday (7/12/19). 1615: Completed soil gas sampling for the day.

Introduction Soil gas and soil samples were collected and analyzed for the Summer 2019 expanded source area investigation during the Department of Veterans Affairs (VA) Remedial Investigation of Operable Unit 2 (OU-2), part of the 700 South 1600 East tetrachloroethene (PCE) Plume in Salt Lake City, Utah, under the Comprehensive Environmental Response, Compensation, and Liability Act. The work was done under contract to the Kansas City District of the U.S. Army Corps of Engineers. CH2M HILL, Inc., a wholly owned subsidiary of Jacobs Engineering Group Inc. (Jacobs), collected samples in accordance with the Modification #1A to the Remedial Investigation Work Plan (RIWP) (Jacobs, 2019) and the original RIWP (CH2M, 2018a), which included the field sampling plan (FSP) (CH2M, 2018b) and the quality assurance project plan (QAPP) (CH2M, 2018c). Analytical data were evaluated by Jacobs as described in the QAPP. This quality control summary report (QCSR) summarizes the chemical data quality review for the samples collected by Jacobs. This QCSR covers 10 soil gas samples, 1 soil gas field duplicate (FD), 9 soil samples, and 1 soil FD. These samples were reported under five sample delivery groups (SDGs) by the laboratories. Samples were collected between June 25 and July 16, 2019, and were analyzed for a variety of volatile organic compounds (VOCs) using the methods shown in Table 1-1. The analyses were performed by ALS Environmental Laboratory in Simi Valley, California and EMAX Laboratories, Inc. in Torrance, California. The analytical data packages are included in Appendix A. The data validation reports associated with each data package are provided in Appendix B. The data package completeness checklists are provided in Appendix C. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling AX1009191050SLC 2-1 2. Sampling Activities Sampling was conducted in accordance with the FSP (CH2M. 2018b) and Modification #1A to the RIWP (Jacobs, 2019). Soil gas samples submitted for U.S. Environmental Protection Agency (EPA) Method TO-15 analysis were collected at the frequency of 10 percent of the total number of samples tested using the Inficon HAPSITE. One soil sample was collected at each soil gas probe installed on the VA campus during this event, with the exception of two locations (SB-53 and SB-54) where only gravel backfill was encountered in the borehole, instead of soil. Therefore, no soil samples were collected at those two locations. Table 2-1 presents the list of samples collected as part of this QCSR. Samples were collected and shipped by overnight carrier to the laboratories. Table 2-2 provides the following information sorted by field sample: • Field sample identification • Matrix • Dates of sample collection and sample receipt by the laboratory • Laboratory SDG number • Analytical method Field quality control (QC) samples collected during the sampling event are presented in Table 2-3. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling AX1009191050SLC 3-1 3. Data Quality Evaluation Procedures All samples were evaluated on an SDG-by-SDG basis by Jacobs chemists. Ninety percent of the samples for each analysis were validated at a Stage 2B level, and 10 percent of the samples for each analysis were evaluated using Stage 4 validation review as described in the QAPP (CH2M, 2018c). The data evaluation for Stage 2B included reviewing: (1) chain-of-custody documentation, (2) holding-time compliance, (3) required QC samples at the specified frequencies, (4) flagging for analytical blanks, (5) laboratory control sample/laboratory control sample duplicates (LCS/LCSD), (6) matrix spike and matrix spike duplicates (MS/MSD), (7) surrogate spike recoveries, (8) initial and continuing calibration information, and (9) other method-specific criteria as defined by the QAPP. In addition to the data evaluation listed for Stage 2B, the Stage 4 data evaluation included sample result and instrument response re-calculation and review of instrument outputs (for example, chromatograms and mass spectra) to verify correct peak identification for a selected subset of the data. Field samples were also reviewed to ascertain field compliance and data quality issues, including reviewing equipment blanks (EBs), FDs, and trip blanks (TBs). Data validation flags were assigned in accordance with Section 5 of the QAPP (CH2M, 2018c). These flags, as well as the reason for each flag, are uploaded into the project electronic database and are included in the data validation reports (Appendix B). Multiple flags may be routinely applied to specific sample method/matrix/analyte combinations, but there will be only one final flag. A final flag is applied to the data and is the most conservative of the applied validation flags. The final flag also includes blank sample impacts. The data flags are defined below. • J = Analyte was positively identified. The associated numerical value is the approximate concentration of the analyte in the sample (estimated), or the reported concentration is greater than the instrument detection limit, but less than the QAPP-specified reporting limit. • R = The sample results are rejected due to serious deficiencies in the ability to analyze the sample and to meet QC criteria. The presence or absence of the analyte cannot be verified. • U = Analyte was analyzed for but not detected above the reported method detection limit (MDL), or this analyte was considered not detected due to laboratory or field blank contamination. • UJ = Analyte was analyzed for but not detected above the reported MDL. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample. The overall summaries of the data quality evaluation procedures are outlined in the following subsections. Specific analyte results and samples that were qualified are discussed in the data validation reports (Appendix B) and are summarized in Table 3-1. 3.1 Sample Receipt and Chain-of-Custody Documentation All samples met the custodial possession and transfer requirements. Chain-of-custody documentation is provided in the analytical data packages (Appendix A). The following discrepancies and issues were noted during sample receipt: • The laboratory noted minor discrepancies between the chain-of-custody forms and the sample container labels for SDG 19G035. In this instance, there was no impact on data quality and the laboratory proceeded with the analyses as indicated on the chain-of-custody forms. 3.2 Holding Times Analytical holding times were evaluated against the criteria listed in Table 3-1 of the QAPP (CH2M, 2018c). For methods requiring both sample preparation and analysis, the preparation/extraction holding time is calculated from the time of sampling to the initiation of preparation/extraction. The analysis holding time is calculated from the time of completion of preparation/extraction to the time of completion Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling 3-2 AX1009191050SLC of the analysis, including any required dilutions, confirmation analysis, and reanalysis. For methods requiring analysis only, the holding time is calculated from the time of sampling to completion of the analysis, including any required dilutions, confirmation analysis, and reanalysis. All holding times were met. 3.3 Tuning and Calibration Instrument tuning and calibration was evaluated in accordance with the calibration criteria specified in the method. Tuning and calibration criteria were generally met, with the following exceptions: • The relative response factor criterion of 0.05 was not met for analyte 2-butanone in the initial calibration verification standard and continuing calibration verification standard for EPA Method 8260C. Nine non-detected results were qualified as estimated concentrations and flagged UJ. 3.4 Method Blanks Method blanks are used to monitor each analytical batch for interference and/or contamination from hardware, reagents, and other potential contaminant sources within the laboratory. A method blank is an analyte-free matrix to which all reagents are added in the same amount or proportions as are added to samples. It is processed through the entire analytical procedure along with the samples in the batch. At least 1 method blank is prepared for each analytical batch of 20 samples or less. Method blanks were analyzed at the required frequency and were generally free of contamination, with the following exceptions: • Carbon disulfide was detected less than the reporting limit in a method blank related to EPA Method TO-15. Nine detected results were less than five times the blank concentration and were qualified as non-detected and flagged U. 3.5 Field Duplicates An FD or collocated sample is an independent sample collected as close as possible to the original sample from the same source under identical conditions. FDs for soil and soil gas samples are to be collected and analyzed on a 10 percent basis for analytical laboratory methods or a minimum of 1 per sampling event if fewer than 10 samples are submitted at a time, and are used to document sampling and analytical precision and representativeness. Precision is expressed in terms of the relative percent difference (RPD) between the native and FD sample results. The RPD criterion for FDs is provided in Tables 3-3 and 3-11 of the QAPP (CH2M, 2018c). Qualification is performed on the native sample and associated FD results. FDs were collected and analyzed at the required frequency for soil and soil gas samples and all precision criteria were met. 3.6 Surrogates Surrogates are organic analytes that behave similar to analytes of interest, or have been chemically altered (that is, chemically deuterated), but are not expected to occur naturally in samples. They are spiked into the standards, field samples, and laboratory QC samples before sample analysis. The results of surrogate spikes provide additional information about the possible influence of the matrix on the accuracy of the measurements for organic analyses only. Laboratory surrogate recoveries were compared to the laboratory specific limits. All surrogates met recovery criteria. 3.7 Laboratory Control Samples LCSs are blank spikes made from clean laboratory-simulated matrices spiked with known concentrations of all target analytes of interest. The LCS is carried through the complete sample preparation and analysis procedure. LCSs are designed to check the instrument and method accuracy. At least 1 LCS is prepared for each analytical batch of 20 samples or less. Accuracy and precision criteria are listed in Tables 3-4 and Table 3-11 of the QAPP (CH2M, 2018c). LCSs and LCSDs were analyzed at the required frequency and all recovery criteria were met. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling AX1009191050SLC 3-3 3.8 Matrix Spikes MSs are used to assess the performance of the method by measuring the effects of interferences caused by the sample matrix and reflects the bias of the method for the particular matrix. An MS is an aliquot of environmental sample to which known concentrations of certain target analytes have been added before sample preparation, cleanup, and determinative procedures have been implemented. Target analytes specified in the QAPP are spiked into the MS at concentration levels less than or equal to the midpoint of the calibration curve for each analyte. The MS is processed through the entire analytical procedure along with samples in the batch. MSs are collected at the frequency of 1 for every 20 field samples collected, except for soil gas samples, which are not amenable to matrix spiking. Accuracy and precision criteria are listed in Table 3-4 of the QAPP (CH2M, 2018c). MSs and MSDs were collected at the required frequency and criteria were generally met, with the following exceptions: • The percent recovery of vinyl acetate was zero percent in the MS/MSD for EPA Method 8260C. One non-detected result was rejected from project use and flagged R. 3.9 Internal Standards Internal standards are compounds that are spiked into the standards, field samples, and laboratory QC samples before sample analysis. They are used to quantify the target analytes. Internal standards provide for stable sensitivity and response during every analytical run. An internal standard is used to evaluate the efficiency of the sample introduction process and monitor the efficiency of the analytical procedure for each sample matrix encountered. Internal standard acceptance criteria are listed in Tables 3-3 and 3-11 of the QAPP (CH2M, 2018c) and all criteria were met. 3.10 Field Blanks 3.10.1 Equipment Blanks EBs are used to evaluate sampling device cleanliness and are collected after a sample collection device is subjected to standard decontamination procedures. ASTM Type II reagent grade or organic-free water is poured over or through the sampling device and collected in sample containers for analysis. EBs are collected at the frequency of 1 per 20 samples collected or 1 per day when fewer than 20 samples are collected, except for soil gas samples, which do not require the collection of an EB. EBs were generally free of contamination or the levels of contamination did not result in data qualification, with the following exceptions: • Acetone was detected in EBs related to EPA Method 8260C; the specified EB sample names and results are presented in Table 3-2. Three detected sample results were less than 10 times the blank concentration and were qualified as non-detected and flagged U. 3.10.2 Trip Blanks TBs are used to assess the potential introduction of contaminants from sample containers during the transportation or storage of samples. A TB consists of a vial filled at the laboratory with ASTM Type II reagent grade or organic-free water, transported to the sampling site, handled like an environmental sample, and returned to the laboratory for analysis. TBs are prepared and used only when samples are being collected and analyzed for VOC compounds. Each cooler of samples sent to the laboratory for VOC analysis contained one TB. TBs were generally free of contamination, with the following exceptions: • Acetone was detected in a TB related to EPA Method 8260C. Three detected sample results were less than 10 times the blank concentration and were qualified as non-detected and flagged U. Low Level Detects Sample results between the MDL and the reporting limit were flagged J. These qualified results represent values determined at levels where the true value of the measured chemical could not be quantified with a high degree of confidence. The laboratory met the QAPP-specified reporting limits. All data flagged for low-level imprecision were the result of the sample concentrations and not laboratory related. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling 3-4 AX1009191050SLC 3.11 Overall Assessment The final activity in the data quality evaluation is an assessment of whether the data meet the data quality objectives. The goal of this assessment is to demonstrate that a sufficient number of representative samples were collected, and the resulting analytical data can be used to support the decision-making process. The following subsections present the field completeness, analytical data completeness, and project completeness for this sampling event. 3.11.1 Field Completeness Field completeness for sample collection was assessed by comparing the number of samples properly collected to the number of samples planned for collection. As shown in Table 2-1, 10 normal soil gas and 11 normal soil samples were planned for sample collection. The appropriate number of soil and soil gas QC samples were collected with the exception of two soil samples that were not collected from locations SB-53 and SB-54 as discussed in Section 2. The field completeness is 90.5 percent. 3.11.2 Analytical Data Completeness Acceptable analytical data are a measure of laboratory contract compliance. Acceptable data include all data that have completed the review or validation process and have not been rejected. The analytical data completeness is 99.9 percent. 3.11.3 Project Completeness Project completeness combines both sampling and analytical protocols to assess the expectations of the project as a whole. Project completeness is calculated using the field and analytical completeness percentages. Overall project completeness for this event is 95.1 percent. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling AX1009191050SLC 4-1 4. Conclusions The overall project completeness was 95.1 percent. The data are acceptable for use as qualified. Quality Control Summary Report Expanded Source Area Investigation 2019 Sampling AX1009191050SLC 5-1 5. References CH2M HILL, Inc. (CH2M). 2018a.

(Jacobs) Date November 24, 2019 Copies to Shannon Smith, CERCLA Program Manager/RPM, Department of Veterans Affairs 1. Background In December 2018, as part of the Operable Unit 2 (OU-2) remedial investigation, shallow soil gas samples were collected adjacent to Veterans Health Administration (VHA) Buildings 6 and 7, near the suspected source area. Elevated concentrations of tetrachloroethene (PCE) were detected in soil gas with concentrations ranging from 14.8 to 3,130 micrograms per cubic meter (µg/m3), above the Environmental Protection Agency (EPA) residential and commercial soil gas vapor intrusion screening levels of 140 and 600 µg/m3. The results are provided in the Operable Unit 2 Remedial Investigation, 2018 OU-2 Data Summary Report (Jacobs, 2019a). In January 2019, a vapor intrusion (VI) investigation was conducted in Buildings 6 and 7 to assess indoor air (IA). This work was performed because the PCE concentrations in soil gas near Buildings 6 and 7, as measured in December 2018, exceeded the screening levels for PCE. Using the Department of Veterans Affairs-owned HAPSITE, it was determined that no IA analytes exceeded their respective screening levels in either Building 6 or 7 after indoor background sources of PCE were removed from Building 6. Because the IA concentrations did not exceed the screening levels as measured by the HAPSITE, and in accordance with the approved VI protocol, no IA samples were collected for laboratory analysis. The results are provided in the Operable Unit 2 Remedial Investigation, 2019 Indoor Air Data Summary Report (Jacobs, 2019b). 2. Purpose and Objectives After the results of the December 2018 soil gas testing and January 2019 VI investigation were reviewed, VHA and USACE agreed that further IA testing would be performed with samples submitted to the lab for testing per EPA Method TO-15. The purpose of this additional IA sampling was to fill two identified data gaps: (1) definitive lab data needed to evaluate the potential for IA impacts resulting from the elevated soil gas PCE concentrations, and (2) lack of laboratory data, which is needed to perform a risk assessment. This additional testing is referred to as the Summer 2019 Indoor Air Investigation. The objectives of the Summer 2019 Indoor Air Investigation are as follows. • The first objective was to confirm the HAPSITE results from the IA survey and collect laboratory data that would support a VI evaluation and an IA risk assessment (performed by others) • The second objective was developed after the first phase of the work (IA sampling) was completed. The objective was to perform a HAPSITE survey in locations where concentrations of elevated PCE or TCE were detected, as measured by laboratory analysis. The survey was done to evaluate if Fall 2019 Indoor Air Investigation 2 AX1114191739SLC PCE- or TCE-containing products were in these buildings, or if there were preferred VI pathways from the sub-slab soil gas into the IA. 3. Indoor Air Sample Collection On September 5, 2019, Jacobs mobilized to the site to deploy the 6-liter summa canisters in locations reviewed and approved by VHA and USACE before mobilization. The sampling plan included 16 IA, 2 ambient air, and 2 duplicates for a total of 20 samples. On September 6, 2019, the summa canisters were retrieved. Problems with some flow controllers and summa canisters were noted at the time. A total of six summa canisters either had an initial vacuum too low to be usable for sample collection, or the pressure regulators did not perform correctly during sample collection, resulting in no sample being collected during the sampling period. Fourteen IA, one ambient air, and zero duplicates were collected for a total of 15 samples. On September 16, 2019, Jacobs re-mobilized to the site to deploy seven summa canisters to collect samples from locations that were previously unsuccessfully sampled. This included four IA, one ambient air, and two duplicates for a total of seven samples. On September 17, 2019, the summa canisters were retrieved. No problems were noted with flow controllers or vacuum for this group of summa canisters. Locations for Buildings 6 and 7 IA samples are provided on Figure 1 and Figure 2, respectively. Daily field activities were recorded in daily reports (Attachment 1). 4. Indoor Air Sample Results Eighteen IA, 2 ambient air, and 2 duplicates were collected for a total of 22 samples. The data were validated upon receipt. All EPA Method TO-15 results for Building 6 IA were below the established risk-based screening level (RBSL). Table 1 provides a summary of the results. TO-15 results for Building 7 IA were also below the RBSL, with the exception of TCE in sample B7-IA05 (8 µg/m3). This sample was collected from the larger of the two basement areas in Building 7. The TCE concentration in this sample exceeded the RBSL (3 µg/m3) but was below the Tier 1 Removal Action Level (8.8 µg/m3). Attachment 2 contains a summary of the data validation. Lab reports are provided in Attachment 3. 5. HAPSITE Survey of Basement Area A survey of the basement areas within Building 7 was deemed necessary because of the detections within the indoor samples, particularly the TCE result for sample B7-IA05. This survey was to evaluate if PCE- or TCE-containing products were in the basement area, or if there were preferred VI pathways from the sub-slab soil gas into the IA. The HAPSITE survey results include one IA sample in the east basement area with a TCE detection of 0.48 µg/m3 (below the reporting level [RL] but equal to the detection level [DL]). All other IA results were below the RL and DL. The breathing zone was surveyed as well as all floor drains and sumps. HAPSITE native data results are presented in Attachment 4. No large floor cracks or utility slab penetrations were noted in the basement areas of Building 7. No PCE- or TCE-containing products were found in the basement areas. 6. References Jacobs, 2019a.

One canister arrived with an initial vacuum of -16 inches of mercury (inHg). This canister was not used since there is chance it leaked (collected air during transit). 1100: Sara Reddinger and Quin Bingham (Jacobs) mobilized to VA Campus. 1130: Met Larry Kellum (VA) at Building 6 and began deploying 6-Liter individually certified stainless-steel summa canisters equipped with 24-hour individually certified clean flow controllers in previously determined locations within Buildings 6 and 7. Additionally, two canisters were placed outside Building 6 and 7 to collect outdoor air samples. Jacobs will check canister vacuum after 20 hours of sampling on 9/5/2019 beginning at 0730 to avoid canister vacuums reaching zero. Canisters will be retrieved at as close to 24 hours after deployment as possible based on vacuums. 1310: A canister was deployed at all previously determined locations. Only one field duplicate was set since one canister arrived with low vacuum. There were 18 sample locations and we received 20 canisters. So, enough for two duplicate samples if all initial canister vacuums were correct. As previously mentioned, one canister arrived with a low vacuum, so it was decided that it was better to collect a sample from all locations and miss one duplicate sample rather than skip one location and have two duplicate samples. 1320: Sarah and Quin left the VA campus.

Five flow controllers did not seem to be functioning correctly since the remaining vacuum after 20 hours did not decrease as it should. Initial canister vacuums were approximately -24 inches of mercury (inHg). The remaining vacuum following 20-hours of sampling should be -5 to -10 inHg, and after 24-hours of sampling the final vacuum should be -2 to -5 inHg. 0810: Jacobs off site 1030: Jacobs on site to check remaining vacuums and retrieve canisters. Some canister required more than 24-hours to achieve a final vacuum near -2 to -5 inHg. 1300: Jacobs completed canister retrieval. 1310: Jacobs completed the chain of custody and boxed canisters for shipment. 1343: Jacobs off site. 1430: Canister dropped at FEDEX shipping center for shipment. Shipment set to arrive at the lab on 9/10. Turnaround time is 2 weeks for analytical results. The following locations were not sampled due to faulty flow controllers (see sample location figures attached): B6-IA04: Building 6 room near breakroom. 23.5-hour remaining vacuum = -24.19 inHg (no analysis requested) B6-IA07: Building 6 northern basement area. Duplicate sample location. Sample B6- IA08 was in this room as well. 23-hour remaining vacuum = -24.42 inHg (no analysis requested) B7-OA01: Building 7 outdoor air (west side). 23-hour remaining vacuum = -21.77 inHg (no analysis requested) B7-IA03: Building 7 main laundry facility. 23-hour remaining vacuum = -22.44 inHg (no analysis requested) PAGE 2 OF 3 Note that no duplicate samples were collected due to two reasons: (1) one canister arrived with a low initial vacuum (see 9/5/19 Daily Report) and (2) sample location B6- IA07 was the duplicate sample location; meaning two canisters were deployed at this location. However, one of the two flow controllers at this location was faulty; therefore, no duplicate sample was collected here, only a normal sample. Also, samples B7-IA07 (shipping warehouse sample) and B7-IA04 (break room) had final vacuums of -13.83 and -14.9 inHg, respectively. These canisters were shipped for analysis. There is a chance there is not enough volume in these canisters for analysis so these locations will be resampled. Jacobs has reached out to the lab and requested they ship us 9 new canisters and flow controllers so Jacobs can return and sample locations that were not able to be sampled during this event due to faulty lab equipment. Once an arrival date for the new sampling equipment is known, Jacobs will coordinate with VA/USACE to set up sample dates. HEALTH AND SAFETY AM WEATHER: 64, P.C. PM WEATHER: 84, P.C.

Calibration range was 2.67 – 537.16 micrograms per cubic meter (µg/m3) for trichloroethene (TCE). Reporting limit (RL) was 2.67 µg/m3. Detection limit (DL) is 0.48 µg/m3. Risk-based screening and the Tier 1 removal action level for TCE is 3 and 8.8 µg/m3, respectively. 1130: Calibration complete. 1200: Began HAPSITE investigation in east basement of Building 7. Approximate area 1000 square feet. Collected three baseline indoor air samples. One indoor air sample collected (where TO-15 canisters was placed) detected trichloroethene (TCE) at a concentration of 0.48 µg/m3 (below the RL but equal to the DL). All other indoor air results were below the RL and DL. Collected samples at all floor drains (6) and one large sump in the east basement of Building 7. All results were below RL and DL. No large floor cracks or utility slab penetrations were present in the east basement of Building 7. Screened grease gun found in east basement of Building 7 for trichloroethene (TCE). No TCE in grease. 1440: Began HAPSITE investigation in west basement of Building 7. Approximate area 375 square feet. Collected one baseline indoor air sample which was below the RL and DL. Collected samples at two floor drains. Both were below the RL and DL. No large floor cracks or utility slab penetrations present in west basement of Building 7. 1530: Ran end of day calibration check.
