Soil vapors were encountered during the routine installation of the underground sewer line in a deep trench (30 feet below grade) at the Site giving rise to worker safety concerns and concerns over potential for vapor intrusion. The vapors were encountered approximately 350 feet from the new school building footprint. The Site is adjacent to a closed landfill. Soil vapor sampling was performed in January and February 2016, including areas near the sewer line, the adjacent landfill and the school building footprint. In the soil vapor samples: hydrogen sulfide was not detected; methane was detected at concentrations exceeding the lower explosive limit in samples collected within 200 feet of the building footprint; and volatile organic compounds were detected widely across the Site at concentrations above the North Carolina residential soil gas screening levels and in one case above the commercial soil gas screening level. Isotopic analysis indicates the methane is most likely from near surface decomposition of organic material rather than from a natural gas source. No pressure differential was observed between the atmospheric pressure and the probe pressure indicating there is not currently a pressure gradient that would drive vapors into the building. Based on the building construction, the commercial soil gas screening levels (SGSLs) may be most appropriate for this structure; however, the North Carolina Department of Environmental Quality (NCDEQ) guidance indicates that due to the use of the structure as a school the residential standard should apply. The NCDEQ DWM guidance states, “When sample results exceed the screening levels, additional evaluation, assessment or mitigation are warranted. However, if any individual sampling result exceeds the screening level that does not mean VI [vapor intrusion] will pose an unacceptable health risk. Sample results can be expected to be variable spatially and temporally, and the DWM screening levels are very conservative and assume a long period of exposure at that level.” 20160086.001A| RAL16R41635 Page 2 June 10, 2016 © 2016 Kleinfelder To further evaluate the potential for vapor intrusion risk at the Site. Sub-slab vapor sampling was performed on April 6, 2016, which included nine sampling locations in the school building footprint. Volatile organic compounds were detected under the building slab; however, the concentrations did not exceed North Carolina residential sub-slab gas screening levels or commercial sub-slab gas screening levels. Methane concentrations were not detected above the action level or lower explosive limit. Soil sampling was performed in March 2016, which included ten soil grab samples located throughout the Site and five soil composite samples of the stockpiles at the multi-purpose field. Volatile organic compounds were detected across the Site from the soil grab samples; however, the concentrations did not exceed the NCDEQ’s Soil-to-Groundwater MSCCs and the NCDEQ’s RSCLs. Volatile organic compounds were detected in two of the stockpile samples exceeded the NCDEQ’s Soil-to-Groundwater Maximum Soil Contamination Concentrations and the NCDEQ’s Residential Maximum Contaminant Concentrations. The concentrations detected were methylene chloride, a common laboratory contaminant. It is Kleinfelder’s opinion that the methylene chloride detected is a laboratory artifact and not representative of actual Site conditions. Three of the soil sampling locations were converted to temporary monitoring wells to facilitate the collection of groundwater samples in areas with the highest soil gas concentrations. Groundwater sampling was conducted in May 2016. The groundwater results did not indicate volatile organic compounds that exceed the NCDEQ, 15A NCAC 02L Groundwater Standards. In summary, soil vapor sampling around the site detected methane and volatile organic compounds at concentrations above screening levels. Subsequent sub-slab vapor sampling under the building footprint detected volatile organic compounds and methane; however, the concentrations did not exceed the screening levels. The NCDEQ DWM guidance on the matter states that “DWM prefers the collection of sub-slab over near slab soil gas samples,” and furthermore states that, “if soil gas concentrations do not exceed the SGSLs, typically no further investigation is necessary….” Kleinfelder is requesting that based on the results to date, the DWM make a determination that further investigation or remedial action is not required at this time. 20160086.001A| RAL16R41635 Page 3 June 10, 2016 © 2016 Kleinfelder 1 GENERAL INFORMATION 1.1 SITE INFORMATION The Site is located at on Holly Springs New Hill Road in Holly Springs, North Carolina (Figure 1). The Site consists of one tax parcel (Wake County Parcel Identification Number 0639958908) which has an area of 23.11 acres (hereafter referred to as the “property” or “Site”) and is currently owned by Wake County Public School System (WCPSS). 1.2 SITE HISTORY Wake County Public Schools, is currently constructing Oakview Elementary School on the subject property. The parcel is adjacent to the closed Holly Springs Landfill 9214-CDLF-1993. A Phase I ESA completed by Mid-Atlantic Associates (MAA May 9, 2014) stated that the property consisted of wooded and cleared land with residential structures and that the subject Site appears to have been wooded and agricultural land back to at least 1959. The Phase I ESA identified one Recognized Environmental Condition (REC) at the property: the presence of a closed construction and debris landfill adjacent to the northeast. Soil vapors were encountered during the installation of an underground sewer line near the northern boundary of the Site. Based on discussions with Site personnel, there were no elevated concentrations of vapors noted during the sewer line excavation until rock blasting was performed. The area where the rock blasting was performed is about 200 feet from the adjacent closed landfill. An evaluation was performed of the air in excavations at the Site on September 8 and 17, 2015 and included measuring organic vapor concentrations using a photoionization detector (PID), oxygen, carbon dioxide (CO2), carbon monoxide (CO), flammable vapors (as percent lower explosive limit (% LEL) calibrated on methane), hydrogen sulfide, and methane. Air screening indicated the presence of subsurface CO between 82 to 171 parts per million (ppm), hydrogen sulfide between 0 to 2.2 ppm, methane between 0 to 8% LEL, and depleted oxygen across the test pits. Later sampling completed in January and February 2016 determined that the elevated concentrations of CO, hydrogen sulfide, and methane observed in the excavations during the September 2015 sampling appeared to have been transient and were not still present. 20160086.001A| RAL16R41635 Page 4 June 10, 2016 © 2016 Kleinfelder 2 SITE GEOLOGY AND HYDROGEOLOGY According to the Geologic Map of North Carolina (Brown, 1985), the Site is located in the Triassic Basin of the Piedmont physiographic province, just to the west of the Raleigh Belt. The regional geology consists of Triassic age consolidated sediments of the Sanford Formation. During subsurface assessment activities, a Kleinfelder licensed geologist noted that the soil appeared to be related to the weathering of arkosic sandstone and mudstone. Surface remnants observed after the blasting activities in the northeast portion of the Site appeared to indicate the presence of arkosic conglomerate. Competent bedrock was encountered onsite from 10 to 30 feet below ground surface (bgs). The United States Geological Survey (USGS) Green Level Quadrangle Topographic Map indicates the direction of groundwater flow to be either to the west-northwest or north-northeast based on the location onsite. Groundwater levels appear to be highly variable based on rainfall with recent groundwater levels of between 5 and 15 feet bgs. 20160086.001A| RAL16R41635 Page 5 June 10, 2016 © 2016 Kleinfelder 3 LIMITED VAPOR INTRUSION ASSESSMENT 3.1 VAPOR PROBE INSTALLATION Soil vapor sampling probes were installed in general accordance with the North Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM), “Vapor Intrusion Guidance (April 2014)” and the NCDEQ Inactive Hazardous Sites Branch (IHSB), “Supplemental Guidelines for the Evaluation of Structural Vapor Intrusion Potential for Site Assessments and Remedial Actions. (March 2014)”. These are collectively called the NCDEQ Guidance in the rest of this report. Kleinfelder generally followed this guidance although the current Site is not within the regulatory oversight of the DWM or IHSB. For unimproved property located within 500 feet of the waste footprint of a landfill, the IHSB guidance suggests soil gas samples should be collected at depths between five and ten feet bgs and if subsurface vapor pathways exist, soil gas samples should be collected at various intervals between five feet bgs and the depth of the base of the landfill waste. To evaluate the potential for vapor intrusion from the landfill (initially presumed source) into the utility trench and to the proposed school building, Kleinfelder installed soil vapor sample probes at 16 locations at the Site (see Figures 2 and 3). Kleinfelder attempted to install probes at the depth of the base of the landfill waste (approximately 70 feet bgs); however, seasonally elevated groundwater was encountered at a depth of approximately 10 to 15 feet bgs. This limited the installation of vapor sampling probes to the 5 to 10 feet bgs interval. On January 18-19 and February 2-3, 2016, soil vapor sampling probes were installed to approximately 5 or 10 feet bgs by Quantex Drilling and Probing. The sample probes were installed using a Geoprobe® DPT rig equipped with 2-inch diameter stainless steel Macro-core® rods. The Macro-core® rods were decontaminated prior to being brought to the Site. Three soil vapor sampling probes (SV-13, SV-15, and SV-16) were installed to approximately 5 feet bgs using a hand auger due to limited access. The soil vapor probes were constructed as follows. Once the soil boring was completed, sand was be placed in the bottom of the boring and a stainless steel sample probe connected to Teflon tubing with Swageloks compression fittings was installed. The boring was then backfilled with 20160086.001A| RAL16R41635 Page 6 June 10, 2016 © 2016 Kleinfelder approximately one foot of sand, followed with approximately one half foot of dry bentonite, and capped with Type I/II Portland cement seal to the ground surface. All backfill and seal materials were placed with a tremie to reduce bridging. The location of vapor probes is shown on Figures 2 and 3. Copies of the sample probe construction records are included as Appendix C. 3.2 SOIL VAPOR SAMPLING Soil vapor sampling methods, including shut-in tests, tracer gas testing, vapor purging, and soil vapor sample collection, were performed consistent with the NCDEQ Guidance. Field data sheets documenting the activities are provided in Appendix D. 3.2.1 Vapor sampling apparatus To collect samples, the vapor probe tubing was connected to a sampling manifold which included two pressure gauges, a flow controller and a series of valves which allows the vapor probe to be purged, monitored, and sampled without allowing ambient air to enter the connections or requiring disturbing the shroud used for leak testing, see photos in Appendix D. Samples were collected in laboratory evacuated one-liter Summa canisters. The summa canisters and sampling manifolds were pre-cleaned and batch certified as clean, and provided by Eurofins Air Toxics Inc. The flow regulator on the canister was set at 0.2 liters per minute (L/Min) by the laboratory. 3.2.2 Sampling apparatus leak detection Prior to mobilization, a shut-in test was performed on the sampling apparatus (canister and manifold) to check for leaks in the fittings of each sample train. The shut-in test consisted of assembling the Summa canister, flow controller, and sampling manifold, and then sealing the “probe” connection point of the manifold with a brass cap and ensuring the purge valve of the manifold was closed. The canister valve was then opened exposing the sampling train to the canister vacuum. The canister vacuum gauge was observed for at least one minute. If there was a noticeably loss of vacuum, the sampling train (canister and manifold) failed the shut-in test and was not used. Consistent with the NCDEQ Guidance, during purging and sampling of each soil vapor probe, a tracer gas test was performed to evaluate and validate sample integrity. A plastic shroud was placed over the entire sampling train and the soil vapor probe tubing connection at ground surface. 20160086.001A| RAL16R41635 Page 7 June 10, 2016 © 2016 Kleinfelder A laboratory grade helium tracer gas was introduced into the shroud. The concentration of helium under the shroud was measured with a Dielectric Model MGD-2002 Helium Detector. The helium concentration under the shroud was maintained at a minimum of 10 percent during the purging and sampling. At the conclusion of the purging, a sample of the purged soil vapor was collected in a Tedlar bag and screened for percentage of helium. If the screened sample contained less than 5% of the helium concentration within the shroud, then the sample flow train integrity was considered adequate and within an acceptable range. If the screened sample contained more than five percent of the helium concentration within the shroud then the equipment was inspected, adjusted, and purged again. The final samples were also analyzed for helium concentration by the laboratory to verify the integrity of the sample. The helium tracer gas concentrations in the SV-10 sample were measured by the laboratory above 5% of the concentration within the shroud during sampling, this indicates that there was a vapor connection between the surface and the soil vapor probe and therefore the data from this point is of limited value. Concentrations of helium in the remaining samples were below 5% of the helium concentration in the shroud for each of those points indicating a competent seal was achieved between the surface and the soil vapor probe. 3.2.3 Vapor Probe Purging Prior to monitoring or sampling each soil vapor probe an SKC pump calibrated to 200 ml/minute was connected to the tubing or manifold to purge the probe and tubing. The vapor probe and tubing were purged by removing three volumes of air (see calculations in Appendix D). 3.2.4 Vapor Probe Monitoring At least 24 hours after probe construction, each vapor probe was purged. After purging was completed, vapor concentrations of LEL, CO, CO2, methane, and hydrogen sulfide were measured using a calibrated GEM 2000+ portable field instrument. The instrument was either attached directly to the probe tubing or the sample was collected through the purge pump and into a Tedlar bag which was screened using the instrument. The pressure differential between the ambient air and the probe was measured by connecting the GEM 2000+ directly to the probe tubing. The sample probes were allowed to equilibrate for at least an additional 24 hours before the 20160086.001A| RAL16R41635 Page 8 June 10, 2016 © 2016 Kleinfelder probes were again purged, monitored, and then sampled. 3.2.5 Vapor Probe Sampling After the second purge and monitoring as described above, the probes were sampled. This second purging, monitoring and sampling occurred on January 21, 2016 and February 9-10, 2016. After purging and monitoring was completed, the purge valve was closed and the manifold valve connected to the one-liter Summa canister was opened and Summa canister filled at the rate of at 0.2 L/M.in. Canister vacuum readings were recorded before and after the sample collection. The soil vapor samples were submitted under chain of custody to Eurofins Air Toxics Inc. (a NELAC accredited laboratory) for volatile organic compounds (VOCs) by Method TO-15 analysis and ASTM D-1946 analysis for fixed gases, including methane and helium. Two additional soil vapor samples were collected from SV-7 and SV-8 on February 10, 2016, for carbon and hydrogen isotopic analysis. Samples were collected in accordance with Pace Analytical Energy Services, LLC procedure F-PAE-Q-031-rev.00. After the purging, monitoring and collection of the TO-15 and ASTM D-1946 samples described above, a Teflon septum was fitted to the purge end of the vapor collection manifold. The purge valve was opened and a new plastic syringe fitted with a stop cock and needle was used to withdraw a sample through the Teflon septum. Once the sample was pulled into the syringe and before the needle was removed from the sample port, the syringe stop cock was closed. When the needle was inserted into the septum on the collection vial, the stopcock was opened and the sample injected into the vial. These samples were collected in 22 milliliter glass vials, with aluminum caps and Teflon septum. The two samples collected on February 10, 2016, were submitted to Pace Analytical Energy Services, LLC (a NELAC accredited laboratory) for isotopic analyses. 3.3 Sub-Slab Vapor Point Installation The sub-slab vapor sampling point construction method used was not included in the NCDEQ Guidance; however, NCDEQ approved the vapor point construction method as an alternative. NCDEQ approval is included in Appendix F. This vapor point construction has been previously accepted by NCDEQ under the Dry-Cleaning Solvent Cleanup Act Program. The vapor point construction method uses a Vapor PinTM, a stainless steel barbed fitting with a silicone sheath that creates a seal with the concrete and a metal cap. This method allows for the installation of 20160086.001A| RAL16R41635 Page 9 June 10, 2016 © 2016 Kleinfelder the sampling point to proceed much quicker and allows the 2-inch diameter cap to be flush with the slab. Kleinfelder followed the sampling method detailed in the NCDEQ Guidance. To evaluate the potential for vapor intrusion from the landfill (initially presumed source) into the school building footprint, Kleinfelder installed sub-slab vapor sample points at nine locations at the Site (see Figure 5). On April 4, 2016, sub-slab vapor sampling points were installed. The sampling points were installed by Quantex Drilling and Kleinfelder. To install the sampling point, a 1.5 to 1.75 inch hole was drilled through the concrete slab and into the fill beneath. The concrete slab was approximately 4 to 6.5 inches thick. The Vapor PinTM was hammered into the hole and fitted with silicone cap and metal cover. The sub-slab vapor sampling points are shown on Figure 5. 3.4 SUB-SLAB VAPOR SAMPLING Sub-slab vapor sampling methods, including shut-in tests, tracer gas testing, vapor purging, and sub-slab vapor sample collection, were performed consistent with the NCDEQ Guidance. Field data sheets documenting the activities are provided in Appendix D. 3.4.1 Vapor Sampling Apparatus To collect samples, the Vapor PinTM was connected to a sampling manifold which included two pressure gauges, a flow controller and a series of valves which allows the Vapor Pin to be purged, monitored, and sampled without allowing ambient air to enter the connections or requiring disturbing the shroud used for leak testing, see photos in Appendix D. Samples were collected in laboratory evacuated one-liter Summa canisters. The summa canisters and sampling manifolds were pre-cleaned and individually certified as clean, and provided by Eurofins Air Toxics Inc. The flow regulator on the canisters were set at 0.2 L/Min by the laboratory. 3.4.2 Sampling Apparatus Leak Detection Prior to mobilization, a shut-in test was performed on the sampling apparatus (canister and manifold) to check for leaks in the fittings of each sample train. The shut-in test consisted of assembling the Summa canister, flow controller, and sampling manifold, and then sealing the “probe” connection point of the manifold with a brass cap and ensuring the purge valve of the 20160086.001A| RAL16R41635 Page 10 June 10, 2016 © 2016 Kleinfelder manifold was closed. The canister valve was then opened exposing the sampling train to the canister vacuum. The canister vacuum gauge was observed for at least one minute. If there was a noticeably loss of vacuum, the sampling train (canister and manifold) failed the shut-in test and was not used. Consistent with the NCDEQ Guidance, during purging and sampling of each sub-slab vapor point, a tracer gas test was performed to evaluate and validate sample integrity. A plastic shroud was placed over the entire sampling train and the sub-slab vapor probe tubing connection at ground surface. A laboratory grade helium tracer gas was introduced into the shroud. The concentration of helium under the shroud was measured with a Dielectric Model MGD-2002 Helium Detector. The helium concentration under the shroud was maintained at a minimum of 10 percent (%) during the purging and sampling. At the conclusion of the purging, a sample of the purged sub-slab vapor was collected in a Tedlar bag and screened for percentage of helium. If the screened sample contained less than 5% of the helium concentration within the shroud, then the sample flow train integrity was considered adequate and within an acceptable range. If the screened sample contained more than 5% of the helium concentration within the shroud then the equipment was inspected, adjusted, and purged again. The final samples were also analyzed for helium concentration by the laboratory to verify the integrity of the sample. Concentrations of helium in the samples were below 5% of the helium concentration in the shroud indicating a competent seal was achieved between the surface and the sub-slab vapor probe. 3.4.3 Vapor Probe Purging Prior to monitoring or sampling each sub-slab vapor probe an SKC pump calibrated to 200 ml/minute was connected to the tubing or manifold to purge the probe and tubing. The vapor probe and tubing were purged by removing three volumes of air (see calculations in Appendix D). 3.4.4 Vapor Probe Monitoring At least 24 hours after probe construction, each vapor probe was purged. After purging was completed, vapor concentrations of LEL, CO, CO2, methane, and hydrogen sulfide were measured using a calibrated GEM 2000+ portable field instrument. The instrument was either attached directly to the probe tubing or the sample was collected through the purge pump and 20160086.001A| RAL16R41635 Page 11 June 10, 2016 © 2016 Kleinfelder into a Tedlar bag which was screened using the instrument. The pressure differential between the ambient air and the probe was measured by connecting the GEM 2000+ directly to the probe tubing. The sample probes were allowed to equilibrate for at least an additional 24 hours before the probes were again purged, monitored, and then sampled. 3.4.5 Vapor Probe Sampling After the second purge and monitoring as described above, the probes were sampled. This second purging, monitoring and sampling occurred on April 6, 2016. After purging and monitoring was completed, the purge valve was closed and the manifold valve connected to the one-liter Summa canister was opened and Summa canister filled at the rate of at 0.2 L/M.in. Canister vacuum readings were recorded before and after the sample collection. The sub-slab vapor samples were submitted under chain of custody to Eurofins Air Toxics Inc. (a NELAC accredited laboratory) for TO-15 analysis (VOCs) and ASTM D-1946 (fixed gases, including methane and helium) analysis. 3.5 SOIL AND GROUNDWATER SAMPLING POINT INSTALLATION Soil and groundwater sampling methods were performed consistent with the NCDEQ Guidance. Field notes documenting the activities are provided in Appendix D. 3.5.1 Drilling Soil borings were advanced using a direct-push drill rig with soil samples screened with a FID. Soil borings DP-1, DP-2, DP-4, DP-5, DP-6, DP-7 and DP-9 were advanced to 5 feet bgs. The grade was 2 feet higher than the final grade at DP-1, DP-2 and DP-4, and the grade was approximate to the final grade at DP-5, DP-6, DP-7 and DP-9. Soil boring DP-9 was advanced within the building footprint which will be a future play area. A temporary monitoring well was not installed in this area due to the potential of being damaged or destroyed by future construction activities. Soil borings DP-3, DP-8 and DP-10 were installed at former vapor points SV-8, SV-13 and SV-14, and the soil borings were advanced to probe refusal. The temporary monitoring wells were 20160086.001A| RAL16R41635 Page 12 June 10, 2016 © 2016 Kleinfelder installed in the borings and consisted of 10 feet length of 1 inch diameter slotted PVC screen threaded to solid 1 inch diameter PVC riser. The well risers extended 1 foot above the ground surface. A sand pack was placed from the bottom of the boring to 1 to 2 feet above the well screen, and then 1 to 2 feet of bentonite was placed above the sand pack. After completion, the wells were purged at least five well volumes of groundwater using a peristaltic pump or pumped dry three times. The equipment was decontaminated between each soil boring. The soil boring logs are provided in Appendix C. The sample locations are provided on Figure 6. 3.5.2 Field Screening of Soil Soil samples collected from the borings and stockpiled soil were screened using a Flame Ionization Detector (FID) to identify VOC contamination. Since the FID calibration gas was methane, elevated readings appear to be related to methane in the subsurface and not petroleum- related impact. Field screening observations and results are reported in Appendix D. 3.5.3 Field Screening of Groundwater The temporary monitoring wells were screened by removing the well cap and inserting the measuring probe into the well. TMW-1 and TMW-2 were sealed 24 hours prior to measurements; however, TMW-3 was not screened because the well cap was not properly sealed. The temporary monitoring wells were screened for percent methane, percent carbon dioxide, percent oxygen, and concentration of carbon monoxide and concentration of hydrogen sulfide reported in ppm. The well screening data is provided in the field notes provided in Appendix C. 3.6 SOIL AND GROUNDWATER SAMPLING 3.6.1 Soil Sampling Soil grab sample depths are indicated on the soil laboratory results Table 3 in Appendix A. Soil composite sampling of stockpiles varied in depth. Soil grab samples and soil composite samples were collected and analyzed for VOCs by USEPA Method 8260. The soil sampling locations are provided on Figure 6. 20160086.001A| RAL16R41635 Page 13 June 10, 2016 © 2016 Kleinfelder 3.6.2 Groundwater Grab Sampling During drilling of the bores, collection of groundwater grab samples was attempted where groundwater was encountered at the three temporary monitoring well locations TMW1/DP-3, TMW2/DP-8 and TMW3/DP-10. Groundwater retrieved from each temporary monitoring well location was transferred to laboratory supplied bottles. Groundwater samples were collected and analyzed for VOCs by USEPA Method 8260. Groundwater laboratory results are in Table 4 in Appendix A. 20160086.001A| RAL16R41635 Page 14 June 10, 2016 © 2016 Kleinfelder 4 RESULTS 4.1 DATA STANDARDS VOC Results of the TO-15 (VOC) analysis were compared to the Sub-Slab and Exterior SGSL as published by the NCDEQ Division of Waste Management (DWM) (September 2015). The DWM publishes two sets of SGSLs, one for residential properties and one for commercial properties. The DWM states in its guidance: “The target soil gas concentration corresponding to a chemical’s target indoor air concentration is calculated by dividing the target indoor air concentration by an appropriate attenuation factor. The attenuation factor represents the factor by which subsurface vapor concentrations migrating into indoor air spaces are reduced due to diffusive, advective, and/or other attenuating mechanisms. For the calculation of SGSLs, DWM uses the IASL associated with a target cancer risk of 1E-05 or a hazard quotient of 0.2 and an attenuation factor (α) of 0.03 for residential exposure and 0.01 for non-residential exposure. Many industrial and commercial buildings have HVAC systems that increase air exchange rates and are typically constructed with thicker, more competent slabs than in residential settings. Increased air exchange rates result in a greater attenuation of contaminants in indoor air, and thicker, more competent slabs may provide an additional barrier to vapor intrusion. It is reasonable to assume a greater attenuation in non-residential settings, therefore; DWM uses a higher attenuation factor for non-residential SGSLs.” However, the guidance further states: “It is DWM policy that day care facilities, schools and any other similar structures where children (under 18) are the primary occupants are evaluated as residential use due to the potentially sensitive nature of the exposed population.” 20160086.001A| RAL16R41635 Page 15 June 10, 2016 © 2016 Kleinfelder The onsite construction management firm, Balfour Beatty, reported that the school building is constructed with an approximately 4 inch thick concrete slab, underlain by a plastic moisture vapor barrier, a porous fill layer made of two layers of stone: 4 inches of #57 stone directly below the moisture vapor barrier and another 4 inches of ABC below that. The moisture vapor barrier was reported to be a Stego Wrap Vapor Barrier which is a 15 mil thick polyolefin vapor barrier. The vapor barrier edges were reported to be taped with Stego Tape per the specifications. (See Appendix E). Based on this construction the commercial SGSLs may be the most appropriate for this structure; however, the guidance quoted above indicates that due to the use of the structure as a school the residential standard should apply. For comparison purposes the data collected from this assessment is compared to both the residential and the commercial SGSLs. The DWM guidance states, “When sample results exceed the screening levels, additional evaluation, assessment or mitigation are warranted. However, if any individual sampling result exceeds the screening level, that does not mean VI [vapor intrusion] will pose an unacceptable health risk. Sample results can be expected to be variable spatially and temporally, and the DWM screening levels are very conservative and assume a long period of exposure at that level.” Methane Methane is an asphyxiant and is combustible and potentially explosive when it is present at concentrations in excess of 53,000 parts per million by volume (ppmv) in the presence of ambient concentrations of oxygen. This concentration is referred to as the Lower Explosive Limit (LEL). In order to provide some margin of safety, a concentration of approximately 10% of the LEL or 5,000 ppmv in ambient air is commonly utilized as an “action level” above which mitigation measures may be considered. Kleinfelder compared methane concentrations to the California EPA advisory on methane assessment at school sites (DTSC 2005), which is generally accepted as being protective of human health. Per this guidance a potential problematic accumulation of methane within a structure could be caused under the following conditions: • Sub surface methane concentration in excess of 53,000 ppmv and sufficient volume to produce elevated gas levels on the interior of the structure; and • An elevated sub surface gas pressure (e.g. greater than 0.1 psi) sufficient to induce flow into the building. 20160086.001A| RAL16R41635 Page 16 June 10, 2016 © 2016 Kleinfelder Isotopic Analysis The ratios of the stable isotopes of carbon (12C and 13C) and hydrogen (1H and 2H) within methane gas varies depending on the process by which the methane was produced. The two principal methods of methane production are biological reduction of organic matter by microbes at shallow depths (biogenic production) and non-biological thermal decomposition of deeply buried organic matter (thermogenic production). Biogenic production can occur by fermentation of organic matter and dissociation of acetate or through the reduction of carbon dioxide. Biogenic methane is typically associated with shallow buried organic material such as trace organics is soil, yard waste, animal waste or landfill material. Thermogenic methane is typically associated with petroleum and natural gas reserves. Each process has a unique isotopic fingerprint (Hackley et. al., 1996; Kaplan et. al., 1997) that is commonly used to evaluate the general source of methane found at sites. This is done by plotting the isotopic signature of samples collected at a site on a graph of established isotopic relationships for each methane production process. Soil and Groundwater Results of soil and groundwater VOC analysis were compared to the Groundwater Screening Level (GWSL) for vapor intrusion as published by the NCDEQ DWM (September 2015). As described above, the DWM publishes two sets of GWSLs, one for residential properties and one for commercial properties. For comparison purposes the data collected from this assessment is compared to both. Results of soil VOC analysis were also compared to the NCDEQ’s Soil-to-Water Maximum Soil Contamination Concentrations (MSCCs) and the NCDEQ’s Residential MSCCs. Results of groundwater VOC analysis were also compared to NCDEQ Groundwater Quality Standards, 15A NCAC 02L .0202 (2L Standard). 4.2 SAMPLE RESULTS 4.2.1 Soil Vapor Sampling Results VOC Results of VOC analysis identified 23 VOCs present in the soil vapor at concentrations above the laboratory reporting limits. Of these, 6 VOCs were present above the residential SGSLs (benzene, ethyl benzene, m,p-xylene, 1,2,4-trimethylbenzene, 1,3 butadiene, and chloroform). Only one of 20160086.001A| RAL16R41635 Page 17 June 10, 2016 © 2016 Kleinfelder the identified VOCs (chloroform) was observed at concentrations that exceeded the non- residential SGSLs, and that occurred in only one sample location (SV-8). Results are presented on Figure 3, and in Table 1 in Appendix A. A laboratory data package is presented in Appendix B. Methane Methane was detected at concentrations above the laboratory reporting limits in seven sample locations. Of those, only three locations (SV-1, SV-7, and SV-8) contained methane at concentrations above the 0.5% action level. Results are presented on Figure 2 and in Table 2 in Appendix A. A laboratory data package is presented in Appendix B. Pressure Subsurface pressure was assessed with the field instrument by measuring the pressure in the pressure in the sampling probes with respect to atmospheric pressure. No pressure differential was observed between the atmospheric pressure and the subsurface probe. Isotopic Analysis The stable isotope ratios of carbon and hydrogen were plotted against isotopic ratios from past research (Hackley et. al., 1996) in Figure 4 the isotopic signatures of the methane samples collected at the Site are generally similar to that of biogenic gas production Discussions with the laboratory indicted that the fact that the data plots more to the right on the graph is expected as the plots were developed approximately 20 years ago. Results are presented in Figure 4 and in Table 3 in Appendix A. A laboratory data package is presented in Appendix B. 4.2.2 Sub-Slab Vapor Sampling Results VOC Results of VOC analysis identified 19 VOCs present in the sub-slab vapor at concentrations above the laboratory reporting limits. The VOCs present do not exceed the residential SGSLs or non- residential SGSLs. Results are presented on Figure 3, and in Table 1a in Appendix A. A laboratory data package is presented in Appendix B. 20160086.001A| RAL16R41635 Page 18 June 10, 2016 © 2016 Kleinfelder Methane Methane was detected at concentrations above the laboratory reporting limits in three sample locations. The methane concentrations present do not exceed the 0.5% action level or the 5% LEL. Results are presented on Figure 2 and in Table 2b in Appendix A. A laboratory data package is presented in Appendix B. Pressure Sub-slab pressure was assessed with the field instrument by measuring the pressure in the sampling point with respect to atmospheric pressure. No pressure differential was observed between the atmospheric pressure and the sub slab. 4.2.3 Soil and Groundwater Sampling Results VOC VOC concentrations from soil grab samples detected four VOCs above the laboratory reporting limits. The VOCs present do not exceed the NCDEQ’s Soil-to-Water or the Residential MSCCs. Stockpile composite VOC sample concentrations were detected above the laboratory reporting limits for seven VOCs. The VOCs present do not exceed the NCDEQ’s Soil-to-Water or the Residential MSCCs except for two sample locations. Methylene chloride concentrations exceeded NCDEQ’s Soil-to-Water MSCC at sample locations SC-2 and SC-3. Methylene chloride is a common laboratory contaminant and is not considered to represent Site conditions. Results are presented in Table 3 in Appendix A and the laboratory data package is presented in Appendix B. Results of VOC analysis identified six VOCs present in the groundwater at concentrations above the laboratory reporting limits. The VOCs present do not exceed the NCDEQ, 15A NCAC 02L Groundwater Standards. Results are presented in Table 4 in Appendix A and the laboratory data package is presented in Appendix B. 20160086.001A| RAL16R41635 Page 19 June 10, 2016 © 2016 Kleinfelder 5 CONCLUSIONS Based on the investigation Kleinfelder offers the following conclusions: • VOCs are present in the soil vapor at wide spread locations across the site and the adjoining property. The VOCs are present in the soil gas outside of the building footprint above the residential SGSLs (benzene, ethyl benzene, m,p-xylene, 1,2,4- trimethylbenzene, 1,3 butadiene, and chloroform) and in one location above the non-residential SGSLs (chloroform). However, sub-slab vapor sampling shows that the VOC concentrations directly beneath the building footprint did not exceed the residential or non-residential SGSLs. • Methane concentrations were detected above the 0.5% action level in soil vapor samples collected from three locations, SV-1, SV-7, and SV-8. Methane generation is most likely from recent near surface decomposition. Methane concentrations directly beneath the building footprint were not detected above the 0.5% action level or the 5% LEL. • No pressure differential was observed between the atmospheric pressure and the probe pressure indicating there is not an existing gradient that would drive vapors into the building. • VOCs are present in the soil at various locations across the Site. VOCs are present in the soil above the Soil-to-Water MSCC (methylene chloride) at two stockpile sampling locations. The methylene chloride detected is considered to be a laboratory artifact and is, in Kleinfelder’s opinion, not representative of actual Site conditions. VOCs are present in the groundwater at all three temporary monitoring well sampling locations. The VOC concentrations did not exceed the NCDEQ 15A NCAC 02L Groundwater Standards. In summary, soil vapor sampling around the site detected methane and volatile organic compounds at concentrations above screening levels. Subsequent sub-slab vapor sampling under the building footprint detected volatile organic compounds and methane; however, the concentrations did not exceed the screening levels. The NCDEQ DWM guidance on the matter states that “DWM prefers the collection of sub-slab over near slab soil gas samples,” and furthermore states that, “if soil gas concentrations do not exceed the SGSLs, typically no further investigation is necessary….” Kleinfelder is requesting that based on the results to date, the DWM make a determination that further investigation or remedial action is not required at this time. 20160086.001A| RAL16R41635 Page 20 June 10, 2016 © 2016 Kleinfelder 6 LIMITATIONS Kleinfelder’s work was performed in a manner consistent with that level of care and skill ordinarily exercised by other members of its profession practicing in the same locality, under similar conditions, and at the date the services are provided.

The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode. This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts. There was a significant difference (greater than 5.0" Hg) between the measured canister receipt vacuum and that which was reported on the Chain of Custody (COC) for sample SV8. A leak test indicated that the valve was functioning properly. Samples SV6, SV2, SV3, SV4 and SV4 Dup were received with significant vacuum remaining in the canister. The residual canister vacuum resulted in elevated reporting limits. Receiving Notes All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page. Dilution was performed on samples SV1 and SV3 due to the presence of high level target species. Analytical Notes Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue Definition of Data Qualifying Flags Page 3 of 31 EPA METHOD TO-15 GC/MS FULL SCAN Summary of Detected Compounds Client Sample ID: SV1 Lab ID#: 1601347A-01A (ug/m3)(ug/m3)(ppbv)(ppbv)Compound AmountRpt.

The laboratory performed analysis via Modified ASTM Method D-1946 for Methane and fixed gases in air using GC/FID or GC/TCD. The method involves direct injection of 1.0 mL of sample. On the analytical column employed for this analysis, Oxygen coelutes with Argon. The corresponding peak is quantitated as Oxygen. Since Nitrogen is used to pressurize samples, the reported Nitrogen values are calculated by adding all the sample components and subtracting from 100%. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications. Requirement ATL ModificationsASTM D-1946 Calibration A single point calibration is performed using a reference standard closely matching the composition of the unknown. A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor. Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component. The standards used by ATL are blended to a >/= 95% accuracy. Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL. The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum. Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%. Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix. Precision Precision requirements established at each concentration level. Duplicates should agree within 25% RPD for detections > 5 X's the RL. Page 3 of 18 Receiving Notes There was a significant difference (greater than 5.0" Hg) between the measured canister receipt vacuum and that which was reported on the Chain of Custody (COC) for sample SV8. A leak test indicated that the valve was functioning properly. Samples SV6, SV2, SV3, SV4 and SV4 Dup were received with significant vacuum remaining in the canister. The residual canister vacuum resulted in elevated reporting limits. There were no analytical discrepancies. Analytical Notes Seven qualifiers may have been used on the data analysis sheets and indicate as follows: B - Compound present in laboratory blank greater than reporting limit. J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the detection limit. M - Reported value may be biased due to apparent matrix interferences.

The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode. This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts. Samples SV3, SV9, SV13, SV1 and SV16 were received with significant vacuum remaining in the canister. The residual canister vacuum resulted in elevated reporting limits. Sample collection date was incomplete on the Chain of Custody for samples SV3, SV10, SV9, SV14, SV13, SV1, SV16, SV8 and SV7. The year of collection was assumed to be 2016. Receiving Notes Dilution was performed on sample SV8 due to the presence of high level target species. All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page. Target compound non-detects in the samples that are associated with high bias in CCV analyses have not been flagged. Analytical Notes Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition.

The laboratory performed analysis via Modified ASTM Method D-1946 for Methane and fixed gases in air using GC/FID or GC/TCD. The method involves direct injection of 1.0 mL of sample. On the analytical column employed for this analysis, Oxygen coelutes with Argon. The corresponding peak is quantitated as Oxygen. Since Nitrogen is used to pressurize samples, the reported Nitrogen values are calculated by adding all the sample components and subtracting from 100%. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications. Requirement ATL ModificationsASTM D-1946 Calibration A single point calibration is performed using a reference standard closely matching the composition of the unknown. A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor. Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component. The standards used by ATL are blended to a >/= 95% accuracy. Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL. The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum. Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%. Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix. Precision Precision requirements established at each concentration level. Duplicates should agree within 25% RPD for detections > 5 X's the RL. Page 3 of 20 Receiving Notes Samples SV3, SV9, SV13, SV1 and SV16 were received with significant vacuum remaining in the canister. The residual canister vacuum resulted in elevated reporting limits. Sample collection date was incomplete on the Chain of Custody for samples SV3, SV10, SV9, SV14, SV13, SV1, SV16, SV8 and SV7. The year of collection was assumed to be 2016. There were no analytical discrepancies. Analytical Notes Seven qualifiers may have been used on the data analysis sheets and indicate as follows: B - Compound present in laboratory blank greater than reporting limit. J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the detection limit. M - Reported value may be biased due to apparent matrix interferences.

The laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode. This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts. Sample collection date was incomplete on the Chain of Custody. The year of collection was assumed to be 2016. The Chain of Custody (COC) information for sample IVP-5 did not match the information on the canister with regard to canister identification. The client was notified of the discrepancy and the information on the canister was used to process and report the sample. Receiving Notes There were no analytical discrepancies. Analytical Notes Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition. UJ- Non-detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence. File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue Definition of Data Qualifying Flags Page 3 of 31 EPA METHOD TO-15 GC/MS FULL SCAN Summary of Detected Compounds Client Sample ID: IVP-1 Lab ID#: 1604137A-01A (ug/m3)(ug/m3)(ppbv)(ppbv)Compound AmountRpt.

The laboratory performed analysis via Modified ASTM Method D-1946 for Methane and fixed gases in air using GC/FID or GC/TCD. The method involves direct injection of 1.0 mL of sample. On the analytical column employed for this analysis, Oxygen coelutes with Argon. The corresponding peak is quantitated as Oxygen. Since Nitrogen is used to pressurize samples, the reported Nitrogen values are calculated by adding all the sample components and subtracting from 100%. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications. Requirement ATL ModificationsASTM D-1946 Calibration A single point calibration is performed using a reference standard closely matching the composition of the unknown. A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor. Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component. The standards used by ATL are blended to a >/= 95% accuracy. Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL. The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum. Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%. Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix. Precision Precision requirements established at each concentration level. Duplicates should agree within 25% RPD for detections > 5 X's the RL. Page 3 of 18 Receiving Notes Sample collection date was incomplete on the Chain of Custody. The year of collection was assumed to be 2016. The Chain of Custody (COC) information for sample IVP-5 did not match the information on the canister with regard to canister identification. The client was notified of the discrepancy and the information on the canister was used to process and report the sample. There were no analytical discrepancies. Analytical Notes Seven qualifiers may have been used on the data analysis sheets and indicate as follows: B - Compound present in laboratory blank greater than reporting limit. J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the detection limit. M - Reported value may be biased due to apparent matrix interferences. File extensions may have been used on the data analysis sheets and indicates as follows: a-File was requantified b-File was quantified by a second column and detector r1-File was requantified for the purpose of reissue Definition of Data Qualifying Flags Page 4 of 18 NATURAL GAS ANALYSIS BY MODIFIED ASTM D-1946 Summary of Detected Compounds Client Sample ID: IVP-1 Lab ID#: 1604137B-01A (%)(%)Compound AmountRpt.
