The monitoring is required by the North Carolina Department of Environmental and Natural Resources (NCDENR) Solid Waste Management Division. This is the thirty-ninth (N=39) monitoring event for the site. This report summarizes the methods used for the groundwater, surface-water, and methane monitoring and presents the results of the sampling event. 3.2 Project Background The Longstreet Road landfill is a closed Municipal Solid Waste Landfill Facility (MSWLF) located north of Longstreet Road at Fort Bragg in Cumberland County, North Carolina. The landfill was closed on August 3, 1999. Figure 1 is a map of the site location. The United States Army Corps of Engineers (USACE), Savannah District has been contracted by the Fort Bragg Directorate of Public Works (DPW) to conduct water quality and methane sampling for the Environmental Branch to satisfy the permit and the Sampling and Analysis Plan (SAP) requirements. Groundwater, surface-water, and methane monitoring locations are shown on Figure 2. The current SAP, approved by NCDENR, includes sampling nine groundwater monitoring wells, two surface-water stations, fifteen methane monitoring wells and four buildings for methane. The groundwater monitoring wells are SLMW-6, SLMW-7R, SLMW-8R, SLMW-9R, SLMW-10, SLMW-11R, SLMW-12AR, SLMW-12BR, and SLMW-13R; the surface- water stations are SW-1 & SW-2; the methane monitoring wells are GP-1R2, GP-2R, GP-3R, GP-4R, GP-5R, GP-6, GP-7, GP-8R, GP-9R, GP-10R, GP-11R2, GP-12R2, GP- 13R2, GP-14R2, and GP-15R2; and the buildings are O-9388, O-9389, the former scale D R A F T 2 house, and the wash rack control booth ( O-9382). In May 2015 three groundwater monitoring wells were installed to the south and east, SLMW-14, SLMW-15 and SLMW- 16. All sampling was conducted according to North Carolina Solid Waste Management Guidelines. 3.3 Project Scope The scope for this project included collecting groundwater samples from the nine wells identified in the SAP as well as the three wells that were installed in May 2015. Groundwater samples were analyzed for all Appendix I and triggered Appendix II constituents. The scope also included collecting two surface-water samples for all Appendix I & II constituents, performing methane monitoring at 15 methane monitoring wells and four buildings on site, evaluating the analytical results, and reporting the results of the investigation. The groundwater sampling and data analyses included obtaining field parameter measurements (i.e. pH, temperature, etc.), measuring water levels at the monitoring well locations, determining groundwater flow directions, validating laboratory analytical data, performing statistical analyses for each detected constituent as required by NC regulations, and determining the concentration changes of chemicals of concern (COCs) with time. 2.0 PROJECT HISTORY 2.1 Site Description The MSWLF is located north of Longstreet Road at Fort Bragg in Cumberland County, North Carolina. Figures 1 and 2 show the site location and layout. The MSWLF is west of the main post and east of Cooleyconch Mountain. Cooleyconch Mountain is the prominent terrain feature west of the main post. A vehicle washing facility borders the site to the east, the Lamont Road LCID and C&D Landfills are approximately 1.5 miles west/northwest of the site (on the west side of Cooleyconch Mountain). D R A F T 3 2.2 General Site Geology and Hydrology Lithologic descriptions of soil borings and monitoring well borings from previous investigations at Fort Bragg indicate that in general Fort Bragg is underlain by alternating sands, silty sands, clayey sands, sandy clays, and clays, likely belonging to the Middendorf Formation. The sands and silty sands range in thickness from approximately 2 to 22 ft and are coarse grained. The clay units range in thickness from approximately 2 to 7 ft and are typically plastic. 2.3 Previous Investigation and Results Several sampling events have been conducted at the Landfill. Initially, four monthly sampling events were conducted in July, August, September, and October 1996 by R, S & H Architect, Engineering, & Planning, Inc. Law & Company, Inc. conducted two sampling events in March and September, 1999 in conjunction with the installation of new wells. Then until 2005, sampling events were conducted by BPA Environmental & Engineering, Inc. The USACE has monitored the site since 2005. The previous sampling event, held in May 2015 for Longstreet Landfill, was conducted by the USACE, Savannah District. Low levels of VOCs, SVOCs, pesticides and Appendix II inorganics were detected, but most detections were below NC2L standards. Monitoring wells, SLMW-8R, SLMW-9R, SLMW-10, SLMW-14 and SLMW-16, contained analytes above the NC2L standard. These wells remain in assessment monitoring. 3.0 METHODS 3.1 Methane Monitoring Methane monitoring was performed at 15 wells and 4 buildings. The monitoring included measuring levels of methane, carbon dioxide, hydrogen sulfide and oxygen at each of the locations. The results of the monitoring are summarized in Table 1 and are D R A F T 4 also presented on Figure 3. 3.2 Water-Level Gauging During this sampling event, USACE personnel measured the water levels in 9 monitoring wells. Measured water levels and calculated groundwater elevations are presented in Table 2. A Potentiometric map was developed based on the groundwater elevations; the map is presented as Figure 4. The map shows that the general direction of the groundwater flow at the Longstreet Landfill is towards the east-southeast. 3.3 Groundwater and Surface-Water Sampling The groundwater sampling was conducted in accordance with the SAP for the Longstreet Road MSWLF (NCDENR Landfill Permit #26-02, which has been updated to reflect the most recent SAP). Groundwater samples were collected from nine monitoring wells and two surface-water stations. Water quality parameters pH, specific conductivity, temperature, turbidity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) were measured during the purge cycle of each well and prior to sampling the surface- water stations. The measurements are summarized in Table 3. The surface-water sampling was conducted using a peristaltic pump. The water to be collected for VOC analysis was not allowed to pass through the head of the pump, instead the tubing was filled and the flow was reversed to fill the bottles. Groundwater samples were collected using a low-flow purge method with a bladder pump. Immediately before purging a well, the static water level below the top of the well casing and the total depth of the well were measured to the nearest 0.01 foot and recorded in the field notebook. The volume of water in the well was calculated based on the static water level and the well construction information. Well volume calculations were placed in the field notebook. The inlet of the sampling pump was placed at the mid-point of the screened interval. This level was adjusted for wells where the static water level is within the well screen. The monitoring wells were purged using a variable-flow bladder pump at a rate of 500 ml/min or less. D R A F T 5 The wells were purged until the water quality had stabilized or five purge volumes were removed. The wells were considered stable when the following requirements were met for three consecutive readings: turbidity values within 10% or lower than 10 Nephelometric Turbidity Units (NTUs), temperature values within a range of 0.5 degrees Celsius, pH readings within 0.1 Standard Units (SU), ORP values within a range of 10 millivolts (mV), and conductivity values within 3%, and DO values within 10%. The rate of pumping was determined and noted in the field notebook. The purge rate was adjusted, as necessary, to avoid purging any well to dryness and to equal the recharge of the aquifer. All sampling equipment was protected from contaminated soil surfaces to prevent contamination of the samples (e.g., equipment may be placed on disposable polyethylene plastic sheeting). Groundwater samples were collected after purging was complete. The tubing was disconnected from the flow through cell and the samples were collected from the pump outlet. The samples were labeled and placed into an ice-filled cooler for preservation. Groundwater sampling data (including sample number, location, quantity of water purged, field parameters, site conditions, etc.) were documented in the field notebook. Water samples for Resource Conservation and Recovery Act (RCRA) metal analyses were un-filtered. The results of the groundwater sampling are presented in Appendix D and on Figure 5. The groundwater sampling field data logs are presented in Appendix A. 3.4 Investigation Derived Wastes Handling The investigation derived wastes (IDW), including the waste water from well purging and decontamination water, were containerized in 55-gallon drums. Those drums were appropriately labeled, sealed, and staged within designated areas until analytical results had been received and reviewed. Based on the analytical results of the groundwater samples, the IDW was classified as non-hazardous. With the concurrence of the Fort Bragg Installation Restoration Program Manager, the IDW was disposed of at an appropriate disposal facility. D R A F T 6 4.0 ANALYTICAL RESULTS AND STATISTICAL ANALYSIS 4.1 Analytical Data Summary Groundwater samples were analyzed for VOCs, SVOCs, Pesticides, PCBs, Organophosphorus Pesticides, and Appendix II Inorganics. The surface-water samples were analyzed for all Appendix I and Appendix II constituents. The summary of detections of the COCs is presented in Appendix D. Figure 5 shows the distribution of the detections and their concentrations from this sampling event. The laboratory reports of analytical results are included as Appendix B. For comparison, the analytical results of previous investigations are also presented in the Statistical Analyses Summary Report included in Appendix C. For comparison, the analytical results of previous investigations are presented in Appendix D. In accordance with North Carolina guidance, analytical results are compared to North Carolina Groundwater 2L Standards (NC2L standards) or the North Carolina Surface Water 2B Standards (NC2B standards). The analytical data of the first 2016 sampling event indicate that some VOCs and inorganics were detected at low levels, and most detections were below NC2L or NC2B standards (Appendix D). Five sampling locations had detections exceeding the remedial standards: wells SLMW-8R, SLMW-9R, SLMW-11R, SLMW-14, and SLMW-16. A summary of the analytical results for each of those wells are as follows: • Well SLMW-8R Two compounds were detected above the 2L standard as listed below: Compound 2L Concentration Benzene 1 µg/L 2.3 µg/L Vinyl Chloride 0.03 µg/L 5.5 µg/L No other constituents were above their 2L standards. D R A F T 7 • Well SLMW-9R Two compounds were detected above the 2L standard as listed below: Compound 2L Concentration Benzene 1 µg/L 2.5 µg/L Arsenic 10 µg/L 24 µg/L No other constituents were above their 2L standards. • Well SLMW-11R Four compounds were detected above the 2L standards as listed below: Compound 2L Concentration Benzene 1 µg/L 1.6 µg/L Tetrachloroethene 0.7 µg/L 1.3 µg/L Trichloroethene 3 µg/L 4.2 µg/L Vinyl Chloride 0.03 µg/L 0.6 J µg/L No other constituents were above their 2L standard. • Well SLMW-14 One compound was detected above the 2L standard as listed below: Compound 2L Concentration Vinyl Chloride 0.03 µg/L 1.5 µg/L No other constituents were above their 2L standard. • Well SLMW-16 Three compounds were detected above the 2B standard as listed below: Compound 2L Concentration Benzene 1 µg/L 2.8 µg/L Vinyl Chloride 0.03 µg/L 2.5 µg/L Arsenic 10 µg/L 15 µg/L No other constituents were above their 2B standard. D R A F T 8 Though samples had constituent detections above method detection limits, all other detections were below the respective NC2L and NC2B standards and most detections were estimated values that were detected above the method detection limits but below the reporting limit (Appendix D). 4.2 Statistical Analysis Results A statistical test predicts the average behavior (distribution) of a random variable by comparing the means (normal distribution) or medians (lognormal and non-parametric distributions) of the compliance well data to background well data. Different statistical tests were used as appropriate for the different distributional patterns that occur within the data. Prior to testing for statistical significance, the distribution of each parameter was determined to be normal, lognormal, or non-normal. If the data were non-normally distributed, or the fraction of nondetects exceeded 15% but were less than 90%, then the Kruskal-Wallis Test was applied. However, the Kruskal-Wallis test is prone to false positives. Therefore, additional statistical analyses were used to determine the validity of the positive results. If the fraction of non-detects exceeded 90%, then the Non-Parametric Prediction Limit was applied. Intra-well comparisons of data from a single well to previous data from the same well were performed to confirm if a trend of increasing concentration is occurring. The Mann- Kendall Trend Analysis and the Shewhart-CUSUM Control Chart statistical tests were selected for these additional analyses. A detailed discussion of the statistical methods is presented in Appendix C. The results of the analysis indicated that the samples collected at the Longstreet Road Municipal Solid Waste Landfill indicated evidence that statistically significant increases (SSIs) were still present in a few wells and that assessment monitoring should continue. According to North Carolina Administrative Code Title 15A Chapter 13 Subchapter B Section 1634 paragraph f [15A NC3AC 13B.1634 (f)], assessment monitoring shall continue if Appendix II parameters are detected at statistically significant levels above background. Assessment monitoring will have to continue at the landfill until the D R A F T 9 presence of no SSIs is confirmed in two consecutive monitoring events. 4.3 Methane Monitoring Results Methane monitoring was performed at 15 wells and 4 buildings. The monitoring included measuring levels of methane, carbon dioxide, hydrogen sulfide and oxygen at each of the locations. The results of the monitoring are summarized in Table 1 and are also presented on Figure 3. One methane monitoring well contained methane at a concentration above 5% by volume, GP-14R2 (9.6% by volume). No other monitoring points or buildings contained high levels of methane (> 5% methane by volume). 5.0 CONCLUSIONS AND RECOMMENATIONS The annual monitoring program consists of two sampling events (this was the first of 2016) conducted six months apart. This was the N=39 sampling event for the Longstreet Road Landfill. Low levels of VOCs, SVOCs, and Appendix II inorganics were detected, but most detections were at estimated levels and/or were below remedial standards. Analytes were detected above the NC2L standards at monitoring wells SLMW-8R, SLMW-9R, SLMW-11R, SLMW-14, and SLMW-16. According to the Statistical Analysis of groundwater Data (Appendix D), the results of the analysis indicated that several locations at the Longstreet Road Municipal Solid Waste Landfill had statistically significant increases (SSIs). According to North Carolina Administrative Code Title 15A Chapter 13 Subchapter B Section 1634 paragraph f [15A NC3AC 13B.1634 (f)], assessment monitoring shall continue if Appendix II parameters are detected at statistically significant levels above background. Assessment monitoring will continue until no SSIs are confirmed in two consecutive sampling events. The methane levels were measured at 19 locations at Longstreet. One methane monitoring well contained methane at a concentration above 5% by volume, GP-14R2 (9.6% by volume). No other monitoring points or buildings contained high levels of D R A F T 10 methane (> 5% methane by volume). 6.0 REFERENCES North Carolina Administrative Code, Title 15A, Department of Environment, Health, and Natural Resources, Division of Solid Waste, Management, Subchapter 13B, Solid Waste Management, Section .1600 (January 4, 1994).

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. RECEIPT The samples were received on 05/13/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 1.3 C. SEMIVOLATILE ORGANIC COMPOUNDS (AQUEOUS) Sample SLMW-12AR-5-16 (680-125233-1) was analyzed for Semivolatile Organic Compounds (Aqueous) in accordance with EPA SW-846 Method 8270D. The samples were prepared on 05/18/2016 and analyzed on 05/24/2016. The continuing calibration verification (CCV) analyzed in batch 680-434682 was outside the method criteria for the following analyte(s): 2-Methylnaphthalene and Nitrobenzene. A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated. . No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. RECEIPT The samples were received on 05/13/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 2.2 C. VOLATILE ORGANIC COMPOUNDS (GC-MS) Samples SLMW-12AR-5-16 (680-125257-1), Trip Blank (680-125257-2) and SLMW-12BR-5-16 (680-125257-3) were analyzed for Volatile Organic Compounds (GC-MS) in accordance with EPA SW-846 Method 8260B. The samples were analyzed on 05/25/2016. Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate/sample duplicate (MS/MSD/DUP) associated with analytical batch 680-434853. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. RECEIPT The samples were received on 05/14/2016; the samples arrived in good condition, properly preserved and on ice. The temperatures of the 5 coolers at receipt time were 1.1º C, 1.7º C, 1.9º C, 2.3º C and 2.3º C. SEMIVOLATILE ORGANIC COMPOUNDS (AQUEOUS) Samples SLMW-12BR-5-16 (680-125287-1), SW-2-5-16 (680-125287-3), SW-1-5-16 (680-125287-4), SLMW-8R-5-16 (680-125287-5) and SLMW-7R-5-16 (680-125287-6) were analyzed for Semivolatile Organic Compounds (Aqueous) in accordance with EPA SW-846 Method 8270D. The samples were prepared on 05/17/2016 and 05/18/2016 and analyzed on 05/21/2016 and 05/24/2016. The laboratory control sample and the laboratory control sample duplicate (LCS/LCSD) for preparation batch 680-433686 and analytical batch 680-434291 recovered outside control limits for the following analyte: 3,3'-Dichlorobenzidine. 3,3'-Dichlorobenzidine has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. Several analytes failed the recovery criteria low for the MS/MSD of sample SLMW-12BR-5-16 (680-125287-1) in batch 680-434682. 2-Chlorophenol exceeded the RPD limit. Several analytes failed the recovery criteria low for the MS of sample SW-2-5-16 (680-125287-3), 3,3'-Dichlorobenzidine failed the recovery criteria low for the MSD, and 3,3'-Dichlorobenzidine and 4-Chloroaniline exceeded the RPD limit in batch 680-434291. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PESTICIDES AND PCBS Samples SLMW-12BR-5-16 (680-125287-1), SW-2-5-16 (680-125287-3), SW-1-5-16 (680-125287-4), SLMW-8R-5-16 (680-125287-5) and SLMW-7R-5-16 (680-125287-6) were analyzed for Pesticides and PCBs in accordance with EPA SW-846 Method 8081B_8082A. The samples were prepared on 05/17/2016 and analyzed on 05/19/2016. Surrogate recovery for the following sample was outside control limits: SLMW-8R-5-16 (680-125287-5). Re-extraction and/or re-analysis was performed with concurring results. The original analysis has been reported No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. ORGANOPHOSPHORUS PESTICIDES Samples SLMW-12BR-5-16 (680-125287-1), SW-2-5-16 (680-125287-3), SW-1-5-16 (680-125287-4), SLMW-8R-5-16 (680-125287-5) and SLMW-7R-5-16 (680-125287-6) were analyzed for organophosphorus pesticides in accordance with EPA SW-846 Method 8141B. The samples were prepared on 05/18/2016 and analyzed on 05/23/2016 and 05/24/2016.
