The Site is comprised of one land parcel that is approximately 10.24 acres in size and contains a two-story approximately 35,000 sq. ft building located in the north -central portion of the Site that is currently used for police department operations. The Site topography consists of an elevated area where the police building and associated parking lots are located which slopes along an embankment to the south to a lower area along Bolin Creek where the Bolin Creek Trail is located. Site topography is indicated in Figure 1. Previous assessment activities indicate that the Site was initially used as a borrow pit from the late 1950s to early 1960s, and then was used as a fill Site from the mid-1960s to the mid-1970s. It was reported that the fill initially consisted of construction debris, and then coal combustion products (CCPs) were placed above the construction debris for structural fill. Previous environmental assessment activities were conducted from 2013 to 2017 which culminated in the completion of a Phase II Remedial Investigation (RI) Report for the Site dated August 14, 2017. Additional background information and the results of previous assessment activities are provided in the Phase II RI Report. In 2019, the Town of Chapel Hill (Town) contracted Duncklee & Dunham (D&D) and Dr. Ken Rudo of Rudo Toxicological Consultants (Rudo) to complete a Human Health and Ecological Risk Assessment for the subject Site. Prior to performing the Human Health and Ecological Risk Assessment, D&D and Rudo identified certain data gaps and requested that additional assessment be completed to support the risk assessment activities. H&H performed the assessment activities in April 2019 which included collection and analysis of groundwater 1 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS samples from the existing monitoring well network, and collection and analysis of indoor air, soil, CCP, sediment, and surface water samples. Results from the April 2019 assessment activities are documented in a Results of Data Gap Sampling Report dated May 23, 2019. The results of Phase II RI and data gap sampling activities are also summarized in the attached summary tables. Following completion of data gap sampling activities, the Town requested that H&H perform the following additional assessment (referred to herein as post -data gap assessment): • Collect samples in drainage pathways along the lower portion of Site to evaluate near surface (0-2 inch) concentrations of metals in soil/CCPs. Previous samples from these areas had been collected starting at a depth of 2 inches. • Expand the existing monitoring well network to further evaluate the location of CCPs in relation to the water table. H&H performed these activities in August and September 2019 and February 2020. A brief description of the methods and results of the post -data gap assessment activities are provided below. It should be noted that Interim Remedial Measures (IRMs) are currently being implemented at the Site which will include excavation and off -Site disposal of erosional CCPs in Areas G, H, and I (Figure 2). As such, some sample locations from drainage pathways which are documented in this report have or are in the process of being excavated. 2 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 2.0 Scope of Work H&H performed post -data gap assessment activities on August 27, 2019, from September 23 through 26, 2019, and from February 6 through 13, 2020. The assessment activities were conducted in general accordance with the North Carolina Department of Environmental Quality's (DEQ's) Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines) and most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures. Prior to conducting the assessment activities, H&H contacted North Carolina 811 One -Call, the public utility locator service, to mark subsurface utilities at the Site. In addition, H&H obtained a bedrock well permit (W20-0030) from the Orange County Health Department on February 4, 2020 prior to installation of bedrock well MW-11D. After collection, sample locations (other than the existing surveyed monitoring wells) were estimated using a sub -meter global positioning system (GPS) unit. The locations of historical and recently collected groundwater and drainage pathway samples are provided in Figure 2. 2.1 Drainage Pathway Soil and Soil/CCP Sampling Activities H&H conducted the sampling of drainage pathways identified in the lower portion of the Site between the embankment and Bolin Creek on August 27, 2019. Based on a request by D&D, a soil sample was also collected in the vicinity of previously advanced boring SS-3. Sampling activities included advancement of seven shallow (approximately 0-2 inches below ground surface [bgs]) soil borings in the following locations using a decontaminated stainless -steel hand trowel: • H&H collected samples of soil/CCPs at previously sampled locations SS-3A, SED-11, SED-16, and SED-17. Previous samples from these locations were collected from these borings at approximately 2-6 inches bgs with the exception of SS-3, which 3 \\hhfs0l\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS was collected from approximately 2-12 inches bgs. The borings were advanced near or within erosional CCP Areas H (SS-3A, SED-16, and SED-17) and I (SED-11). • H&H collected samples of soil at previously sampled locations SED-12, SED-13, and SED-15. Historical samples from these locations were collected from these borings at approximately 2-6 inches bgs. These samples were collected outside of erosional CCP Areas G, H, and I. At each location, soil and soil/CCP samples were collected for laboratory analysis from the center of the decontaminated hand trowel, homogenized in a stainless -steel bowl, and then the samples were placed into laboratory containers for analysis. Locations of soil and soil/CCP sampling locations are shown on Figure 2. 2.2 Monitoring Well Installation On September 23 and 24, 2019 H&H contracted with SAEDACCO to install three additional permanent monitoring wells (MW-IA, MW-8, and MW-9) and one temporary monitoring well (TMW-10) via roto-sonic drilling techniques within the fill areas at the Site. Based upon field observations during the September 2019 drilling activities and water level data collected after the well installations, both which indicated the potential presence of perched groundwater zones in the fill materials, SAEDACCO returned to the Site on February 5 through 11, 2020 to install one permanent bedrock monitoring well (MW-1113) via hollow -stem auger/air rotary drilling techniques below the fill materials adjacent to well MW-9. A perched groundwater zone is a layer of groundwater that is separated from the underlying main aquifer zone by a zone which does not contain groundwater. A zone of perched groundwater is typically underlain by a layer of soil or rock which has a lower permeability than the surrounding area which limits downward percolation of groundwater. Permanent and temporary monitoring well locations (denoted by MW and TMW nomenclature, respectively) are shown on Figure 2 and were advanced in the following locations: 4 \\hhfs0l\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS • MW-IA was installed in the vicinity of existing monitoring well MW-1 in the western portion of the CCP placement area. MW-1 was installed by Falcon Engineering (Falcon) in 2013 and H&H was unable to locate a boring log for MW-1 from Falcon's reports. As such, MW-IA was installed to provide lithologic information for the MW-1 area. In addition, MW-IA was installed to evaluate discrepancies between CCP-related information provided in Falcon's reports and the driller's log for nearby historical boring GP-1. MW-IA was also installed because groundwater samples from well MW-1 have indicated elevated turbidity during some previous sampling events which resulted in concern that sample analytical results from well MW-1 may be impacted by turbidity. • MW-8 was installed in the vicinity of historical boring GP-6 to verify the location of CCPs in the eastern portion of the CCP placement area relative to the water table and to provide additional groundwater data in the fill area. • MW-9 was installed in the vicinity of historical borings GP-2/GP-3 to verify the location of CCPs in the western portion of the CCP placement area relative to the water table and to provide additional groundwater data in the fill area. • TMW-10 was installed in the vicinity of historical boring GP-11 to verify the location of CCPs in the western portion of the CCP placement area relative to the water table and for the purpose of collecting one-time depth to groundwater information. • MW-11D was installed adjacent to MW-9 to further evaluate potential perched water conditions identified in association with wells MW-9 and MW-IA, and to provide representative samples of groundwater below the fill not impacted by perched water conditions (if present). The first five feet of each boring were advanced using a decontaminated stainless -steel hand auger. During drilling, continuous soil samples were collected from the monitoring well borings and logged for lithologic description and screened using visual and olfactory methods for obvious evidence of non-CCP attributes (i.e., staining and/or unusual odors) and for the presence 5 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS of volatile organic vapors using a calibrated photoionization detector (PID). No obvious evidence of non-CCP attributes was observed in the monitoring well borings. The boring logs are provided in Appendix A. Photographs of cores from the roto-sonic drilling are included in Appendix B. With the exception of MW-I ID, the monitoring wells are constructed of 2-inch diameter PVC with 15 ft of pre -packed well screen (to reduce turbidity) set to bracket the first encountered water zone and 2-inch diameter PVC well casing from the top of the well screen to the ground surface. Monitoring wells MW-IA, MW-8, MW-9, and TMW-10 were installed to depths of 40 ft bgs, 44.5 ft bgs, 45 ft bgs, and 40 ft bgs, respectively. To install bedrock monitoring well MW-11D, hollow -stem augers were advanced to a depth of approximately 43 ft bgs (approximate bedrock interface with partially weather rock [PWR]) followed by an air rotary hammer to approximately 45 ft bgs. A 6-inch diameter PVC outer well casing was then installed and grouted with Portland cement to the ground surface. Once the grout solidified after a period of approximately 24 hours, the drill rig advanced the air rotary hammer within the outer casing to a depth of approximately 56 ft bgs. Filter sand packs were installed from the bottom of each well boring to approximately 2 ft above each well screen, and an approximately 2-foot hydrated bentonite seal was then installed above the filter sand pack followed by AQUAGUARD® well grout (a bentonite well seal mixture) to the ground surface. During well installation for MW-11D, grout inspections of the inner and outer casings were performed by the Orange County Health Department. All monitoring wells were completed flush with the ground surface inside flush mount manholes secured with 2 ft by 2 ft concrete pads. After collection of water levels in TMW-10, the casing was pulled from the boring and the well boring was grouted with cement grout. A summary of well construction and groundwater elevation information is provided in Table 1. Monitoring well boring logs, well construction records, and the well abandonment record for temporary monitoring well TMW-10 are provided in Appendix A. Because of the presence of CCPs in some of the well boring soil cuttings, investigation derived waste (IDW) from the drilling activities was containerized in 55-gallon drums and stored on -Site. 6 \\hhfs0l\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS Following receipt of waste characterization data, the 55-gallon drums were transported off -Site by A&D Environmental Services, Inc. to a permitted facility. A copy of the Non -Hazardous Materials Manifest is included in Appendix C. Based upon the previously collected groundwater analytical data indicating that metals concentrations do not exceed toxicity characteristic hazardous waste thresholds, decontamination and well development water were spread/discharged on the ground in accordance with DEQ IHSB Guidelines. During drilling activities, H&H monitored dust levels using a TSI DustTrak DRX to monitor for potentially elevated dust levels that could lead to dust migration from the area of drilling. There were no dust levels significantly above background during the drilling activities. 2.3 Monitoring Well Sampling H&H collected groundwater samples from newly installed monitoring wells MW-IA, MW-8, and MW-9 on September 26, 2019. On February 12, 2020, H&H returned to the Site to collect groundwater samples from existing monitoring well MW-9 and adjacent newly installed bedrock monitoring MW-11D. Before each sampling event, all Site monitoring wells were gauged for depth to water. After gauging, the monitoring wells which were to be sampled were purged to ensure that water samples obtained from the wells were representative of perched water in the fill or non -perched groundwater. Purging and sampling of the monitoring wells were completed using low flow/low stress method in general accordance with EPA Region 4 SESD protocol. Monitor well MW-9 was purged and sampled using a peristaltic pump with new polyethylene tubing. Due to depths to water greater than 25 ft, monitoring wells MW-IA, MW-8, and MW-111) were purged and sampled using decontaminated bladder pumps connected to new polyethylene tubing. During purging, field measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and conductivity were collected at 3 to 5-minute intervals. Purging was considered complete when water quality parameters stabilized (i.e., pH f 0.1 SU, conductivity varies no more than 5%, and turbidity is less than 10 Nephelometric Turbidity Units [NTUs]). H&H was able to obtain samples with turbidity less than 10 NTUs at each monitor well. The low flow groundwater sampling records are provided in Appendix D. 7 \\hhfs0l\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 2.4 Laboratory Analyses Based upon previous analytical data, the groundwater and drainage pathway soil/CCP samples were analyzed for the Site metals of concern: arsenic, barium, beryllium, cadmium, total chromium, cobalt, copper, manganese, mercury, nickel, and selenium by EPA Methods 6020/7470/7471 and strontium by EPA Method 6010. Soil/CCP samples were also analyzed for hexavalent chromium by EPA Method 7199. In addition, groundwater samples collected from MW-9 and MW-11D during the February 2020 event were analyzed for alkalinity, sodium, calcium, magnesium, and potassium to further evaluate groundwater geochemistry to assist with distinguishing potential perched water in the fill from non -perched groundwater. Upon collection, samples were placed directly into laboratory -supplied sample containers. After sample collection, sample containers were sealed, labeled, placed into a laboratory -supplied sample cooler, and covered with ice. The coolers were then delivered under standard chain -of -custody protocols to Pace Analytical Services, LLC (Pace). 2.5 Quality Assurance/Quality Control (QA/QC) In addition to standard analytical method QA/QC procedures performed by the laboratory, H&H conducted the following field QA/QC activities: • Non -dedicated equipment and tools were decontaminated prior to use at each boring or sampling location, or following exposure to soil/CCPs or groundwater. • A duplicate groundwater sample was collected from MW-9 during the February 2020 sampling event to evaluate data reproducibility. • Equipment blanks were collected by passing laboratory supplied deionized water through decontaminated equipment prior to use and then collecting the water for analysis of the same list of metals as the corresponding samples. A groundwater sample rinse blank was collected during the September 2019 sampling event by pouring the water through the 8 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS peristaltic pump tubing (sample labeled RB). The soil/CCP rinse blank was collected by pouring water over the decontaminated hand trowel during the August 2019 sampling event (sample labeled EB-I). 9 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 3.0 Results Summary The results of analysis of the post -data gap samples are summarized in Tables 1 through 4 along with the historical analytical data. In the tables, the September 2019 sample dates are highlighted in orange, and the February 2020 sample dates are highlighted in blue for ease in referencing the additional data. As was submitted with the May 23, 2019 Results of Data Gap Sampling Report, the April 2019 sample dates are highlighted yellow. The non -highlighted sampling dates were conducted as part of the Phase II RI or pre -Phase II RI activities in the 2013 to 2016 timeframe. The laboratory analytical data is provided in Appendix E. Some observations concerning the data are provided in the following sections. 3.1 Drainage Pathway Soil/CCP Analytical Data The soil/CCP analytical data are summarized in Table 1. The data in Table 1 are compared to Site -specific background sample concentrations and DEQ's Preliminary Soil Remediation Goals (PSRGs) dated July 2020. Note that the range of soil background concentrations and the 95% Upper Confidence Level (UCL) of the mean of the background data are provided in Table 1 and are based upon the results of analysis of the Phase II RI background samples collected in November 2016 and the additional background samples collected in April 2019. The results of analysis of the drainage pathway samples collected from 0-2-inch depth interval within erosional CCP Area I (SED-11) and outside of the erosional CCP areas (SED-12, SED-13, and SED-15) generally indicated similar concentrations of metals as the samples collected previously from the same locations at the 2-6-inch and 2-12-inch depth intervals. Consistent with the previous samples, concentrations of arsenic, barium, and/or selenium were detected above the Site -specific background levels and the DEQ Residential, Industrial/Commercial, and/or Protection of Groundwater PSRGs. Drainage pathway samples collected from the 0-2 inch depth interval in areas near or within erosional CCP Area H (SS-3A, SED-16, and SED-17) indicated at least one of the metals arsenic, barium, manganese, and/or selenium at higher concentrations in comparison to the 10 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS samples collected from the 2-6 inch (August 2019) and 2-12-inch (February 2016) intervals from the same location. Instances of this occurrence include: • arsenic in SS-3/SS-3A (23.4 milligrams per kilogram [mg/kg] vs 4.5 mg/kg); • barium in SS-3/SS-3A (1,080 mg/kg vs 100 mg/kg) and SED-17 (1,420 mg/kg vs 565 mg/kg); • manganese in SED-16 (1,250 mg/kg vs 513 mg/kg); and • selenium in SS-3/SS-3A (3.79 mg/kg vs non -detect [i.e., below laboratory detection limits]). However, in one case the metal concentration was lower in the 0-2-inch sample as compared to the previous 2-6 inch and 2-12-inch samples. In SED-16, arsenic was detected in the 0-2-inch sample at 21 mg/kg and arsenic was detected at 28.3 mg/kg in the 2-6-inch sample. As expected, concentrations of arsenic, barium, manganese, and/or selenium were detected above Site -specific background levels and the DEQ Residential, Industrial/Commercial, and/or Protection of Groundwater PSRGs in samples SS-3A, SED-16, and SED-17. The presence of generally higher levels of metals in samples collected from 0-2 inches as compared to samples collected from the 2-6-inch and 2-12-inch intervals appears to be a function of thickness of the erosional CCP where the sample is taken. Because the amount of erosional CCP decreases with depth, samples collected from the 0-2-inch interval are comprised mostly of CCPs, whereas samples collected from 2-6 inch or 2-12 inches are likely to have increased soil content with depth and thus lower metals concentrations. As previously noted, soil/CCPs associated with all of the erosional CCP areas are in the process of being removed as part of IRMs being conducted from Spring to Fall 2020. Post IRM samples will be collected to document metals concentrations in soil in the erosional CCP areas after the IRMs. 11 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 3.2 Fill Materials Assessment During drilling of the additional monitor well borings, H&H collected continuous soil samples to perform a more detailed evaluation of the fill materials. In general, fill materials consisting of CCPs, construction -like debris (concrete, brick, wood, etc.), and soil were observed at depths up to approximately 40 ft bgs in the monitor well borings (see photographs in Appendix B). The fill materials were covered with approximately 2 to 5 ft of fill soil consisting of sand or clay. The deepest that CCPs were observed in the monitoring well borings was approximately 29 ft bgs in MW-IA. As noted previously, one of the reasons that MW-IA was installed was to evaluate the depth of the CCPs in this area of the Site. The logs for nearby Falcon boring GP-1 indicated CCPs to a depth of 12 ft bgs, and the log for nearby Falcon boring GP-2 indicated CCPs to a depth of 30 ft. There was no Falcon boring log for well MW-1; however, a driller's log for MW-1 indicated CCPs to a depth of 40 ft which was inconsistent with Falcon's logs. As noted in previous correspondence on this issue, driller's logs are intended primarily to document construction details of the wells and that the wells were installed by a certified well driller, not to document lithologic information in detail like a geologist's or engineer's log. Based upon the data collected at MW-IA, we conclude that the CCPs in this area are limited to a depth less than 30 ft bgs and do not extend to 40 ft bgs. Previous reports indicated that construction and demolition materials were initially placed in a borrow pit at the Site and then those materials were covered with CCPs. Previous log data also indicated zones of CCPs ranging from 3 ft thick to 25 ft, with an approximate average thickness of 8 ft. However, the detailed lithologic data collected during installation of the additional monitoring wells indicates that the fill materials consist primarily of construction and demolition debris and fill soil intermixed with thin zones of CCPs ranging from less than 1 ft to 3 ft with some thicker zones. Thicker zones of CCPs were identified in several monitoring well borings as follows: • 19 to 29 ft bgs interval of monitoring well MW-IA; and • 20 to 27 ft bgs interval of temporary monitoring well TMW-10. 12 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS Based upon the lithologic information obtained during the additional monitoring well borings, H&H prepared an updated north to south trending geologic cross-section. The cross-section is presented as Figure 4 and a cross-section transect location map is provided as Figure 3. 3.3 Groundwater Elevation Data A summary of the groundwater elevation data is provided in Table 2. Groundwater elevations were generally consistent between the September 2019 and February 2020 gauging events for monitoring wells located in the upper portion of the Site (MW-1, MW-IA, background well MW-5, and MW-7 through MW-9). However, for monitoring wells located in the lower portion of the Site (MW-3A, MW-4A, and MW-6), depth to groundwater was measured approximately 2 to 6 ft higher during the September 2019 monitoring event, which is expected considering the large amount of rainfall that occurred prior to the event and its impact on groundwater levels in wells near Bolin Creek. As noted previously, the results of this assessment indicate that there is evidence of perched groundwater in the fill material which is separated from the main underlying unconfined aquifer. When a monitoring well is installed in a perched groundwater zone, the perched groundwater will drain into the monitoring well and the water level in the well will rise to the elevation of the groundwater in the perched zone. This gives the impression that the monitoring well screened zone is fully saturated with groundwater from the unconfined aquifer, when in fact it is not. Therefore, multiple lines of evidence are typically used to identify perched groundwater zones such as 1) detailed lithologic information identifying potential zones of saturation, underlying low permeability zones, and underlying unsaturated zones, 2) significant differences in hydraulic head in wells located in close proximity to one another, and 3) differences in natural groundwater geochemistry between perched groundwater and the underlying unconfined aquifer. Uncontrolled fill areas such as the Site, in which layers with significantly different permeabilities are placed next to one another (i.e., debris with sand or a gravel zone immediately overlying a silt or clay layer) have a high potential for perched groundwater zones. 13 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS Evidence of perched groundwater in the fill materials at the Site is supported by the following observations: • In MW-lA, a wet zone containing clay and construction debris at a depth of approximately 29 ft was identified below coal ash and overlying an unsaturated zone. • In MW-9, a wet zone was observed in woody organic materials at approximately 31 to 33 ft bgs above an underlying unsaturated zone. • In TMW-10, wet zones containing clayey sand and some coal ash was observed above an unsaturated zone. • In adjacent wells MW-1 (screened from 30 to 40 ft bgs) and MW-lA (screened from 25 ft to 40 ft), the depths to groundwater in the September 2019 and February 2020 gauging events were approximately 4 to 5 ft higher in MW-1 A as compared to MW-1. • In the Piedmont region where the Site is located, wells screened in different intervals will typically have similar groundwater elevations because the unconfined aquifers (such as the overlying saprolite aquifer and the underlying bedrock aquifer) are fully interconnected. However, in adjacent wells MW-9 (screened from 30 to 45 ft in fill material) and MW-11D (screened from 46 to 56 ft bgs), the groundwater elevation in MW-9 measured in February 2020 is approximately 6 ft higher in MW-9 than in MW-11D. • As noted in the following section, there were significant differences in groundwater geochemical parameters between adjacent wells MW-9 and MW-I ID. A conceptual diagram showing the relationship between perched groundwater and the unconfined aquifer is provided as Figure 5. As indicated in Figure 5, infiltrating rainwater which infiltrates the ground and recharges groundwater may get trapped by low permeability zones in the fill above the unconfined aquifer and form perched groundwater zones. These zones are 14 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS typically laterally discontinuous and only contain thin layers of water. Some of the perched groundwater may seep from the edges of the perched water to the underlying aquifer, although the volume of seepage is typically small, especially in comparison to the volume of water in the underlying aquifer. Because of the apparent presence of perched water zones in the fill materials, H&H prepared an inferred groundwater potentiometric map for the February 2020 gauging event using the groundwater elevation data from wells MW-3A, MW-4A, MW-5, MW-6, MW-7, and MW-I ID which are not screened in the fill materials and which are installed in the underlying unconfined aquifer. The potentiometric map is provided in Figure 6 and indicates that overall groundwater flow is to the southeast. A comparison of the groundwater levels to zones of CCPs indicates that some zones of CCPs may contain perched groundwater or are present just above perched water. However, CCPs do not appear to be present within the main underlying unconfined aquifer. 3.4 Groundwater Analytical Data A summary of the groundwater analytical data is provided in Table 3, and a summary of groundwater field geochemical parameters is provided in Table 4. In Table 3, groundwater analytical data are compared to background (MW-5) and the DEQ 15A NCAC 02L .0202 Groundwater Standards (2L Standards) dated April 2013 or the Interim Maximum Allowable Concentrations (IMACs). Some brief observations concerning the data are provided below: • The results of analysis of the sample collected from newly installed well MW-1 A during the September 2019 event indicate the presence of barium (1,040 micrograms per liter [µg/L] versus 2L Standard of 700 µg/L), cobalt (1.2 µg/L versus IMAC of 1 µg/L), and manganese (1,200 µg/L versus background level of 580 µg/L). The concentrations of these metals are lower than those detected in adjacent well MW-1 in April 2019 when a 15 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd.Aoc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS low turbidity sample was collected from MW-1 (barium: 1,730 µg/L; cobalt: 1.8 µg/L; and manganese: 2,420 µg/L). In MW-IA, arsenic was detected at the 2L Standard of 10 µg/L in February 2020 which is lower than the concentration of 28 µg/L (above the 2L Standard) detected in adjacent well MW-1 in February April 2019. • In MW-8 and MW-9 concentrations of cobalt (up to 4 µg/L in MW-8) and manganese (up to 5,060 µg/L in MW-9) were detected above 2L Standards and background levels in the samples collected during the September 2019 event. • In bedrock well MW-11D which is located below the fill adjacent to MW-9, metals concentrations were significantly lower than those in the fill and no compounds were detected above 2L Standards or IMACs. For example, in MW-111), cobalt was not detected versus a concentration of up to 2.5 µg/L in MW-9. In addition, manganese was detected at 14.7 µg/L in MW-11D (below the 2L Standard of 50 µg/L and background level of 580 µg/L) in comparison to the detection of up to 5,430 µg/L in MW-9. • A review of the geochemistry data between MW-9 and MW-11D also indicates significant differences in water geochemistry between the two wells, which further supports that MW-9 is monitoring perched groundwater in the fill as opposed to groundwater monitored by MW-11D in the unconfined aquifer which underlies the fill. Some examples of differences in geochemical parameters between the two wells are summarized below: Parameter Units MW-9 (Within Fill) MW-11D (Below Fill) Calcium /L 118,000 45,100 Potassium /L 12,400 145,000 Sodium /L 24,900 65,400 Dissolved Oxygen m /L 0.22 2.08 Oxidation Reduction Potential mV -102.3 15.9 Note that dissolved oxygen and oxidation reduction potential data are provided in the groundwater sampling records in Appendix D. 16 \\hhfs0l\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 3.5 QA/QC Sample Summary A brief summary of the QA/QC sample analyses is provided below: • The results of analysis of the duplicate groundwater sample collected from MW-9 indicated generally good correlation with the parent sample. • The results of analysis of the rinse blank samples indicated the presence of trace levels (less than 1 µg/1) of the metals barium and manganese in the groundwater blank sample. Given the trace levels detected of these metals in comparison to the sample concentrations detected and/or screening levels/standards, the concentrations of the metals in the rinse blanks are not expected to have a significant effect on interpretation of the data. 17 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station - Remedial Services and General Support\Post-Data IN Gap Assessment Report\final to client\Results of Post -Data Gap Assessment Report _828 MLK Jr. Blvd..doc hart : h is kman SMARTER ENVIRONMENTAL SOLUTIONS 4.0 Conclusions Based upon the results of the post -data gap assessment activities (as well as other Site data), H&H makes the following conclusions: • Detailed lithologic data collected during installation of the additional monitoring wells indicates that the fill materials consist primarily of construction and demolition debris and fill soil intermixed with thin zones of CCPs ranging from less than 1 ft to 3 ft with some thicker zones up to 10 ft. Fill materials were identified to depths of approximately 40 ft, although the deepest that CCPs were observed was approximately 29 ft. • Based upon the observations made during the additional monitoring well borings, the previous estimate of the amount of CCPs present at the Site (60,000 cubic yards), which was based upon an average thickness of 8 ft over the 4.5-acre area where CCP is present, is likely an overestimate and the actual amount is significantly lower. • Geologic data, groundwater elevation data, and groundwater geochemical data indicate that there are perched water zones in the fill material and that groundwater samples collected from shallow wells in the fill are monitoring these perched zones. Perched groundwater is likely present in some zones of CCPs or just below zones of CCPs. Elevated concentrations of metals in groundwater samples are associated with the presence of CCPs within or near perched groundwater. Some impacted perched groundwater may eventually migrate through underlying unsaturated zones to groundwater in the main underlying unconfined aquifer; however, this migration is slow and of low volume. As such, there is limited or no groundwater impact in monitoring wells which are screened in non -fill zones in the unconfined aquifer, including well MW- 11D located directly below the fill and shallow downgradient monitoring wells MW-3A and MW-4A which are located downgradient of the fill area. 18 \\hhfs0I\MasterFiles\AAA-Master Projects\Town of Chapel Hill (TCH)\TCH-009 - Police Station -
