The monitoring is required by the North Carolina Department of Environmental and Natural Resources (NCDENR) Solid Waste Management Division. This was the thirty-second (N=32) event performed for the site. This report summarizes the methods used for the groundwater and methane monitoring and presents the results of the sampling event. 1.1 Project Background The USACE was contracted by the Directorate of Public Works (DPW), Fort Bragg, North Carolina to perform groundwater sampling and methane monitoring. The original groundwater monitoring well network for the land clearing and inert debris (LCID) and construction and demolition (C&D) landfills consisted of 12 wells. Five of the original eleven monitoring wells have been permanently abandoned and replaced with new wells at different locations. An additional two wells have also been installed. The current Sampling and Analysis Plan (SAP), approved by NCDENR, includes sampling these 13 monitoring wells. The monitoring wells are LMW-3, LMW-3S, LMW-4R, LMW-6, LMW-7R, LMW-8, LMW-9, LMW-9S, LMW-9D, LMW-10, LMW-14R, LMW-15R, and LMW-16. Groundwater monitoring locations are shown on Figure 2. All sampling was conducted according to North Carolina Solid Waste Management Guidelines. D R A F T 2 1.2 Project Scope The scope for this project included collecting groundwater samples from 13 monitoring wells at the Lamont Road LCID and C&D Landfill for analyses of Appendix I constituents, sampling for methane at 13 selected methane monitoring wells and at three additional buildings, 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 analysis for each detected constituent as required by NC regulations, and determining the concentration changes of chemicals of concern (COCs) with time. PROJECT HISTORY 1.3 Site Description and History The Lamont Road LCID and C&D Landfills are on the west side of Cooleyconch Mountain (Figure 2). The site was previously utilized as a maneuver training area (conducted continuously for 50 years), a borrow pit for sands and clays, and a repository for unclassified debris from land clearing and construction demolition. The LCID Landfill started as an uncontrolled dump site which was associated with reclaiming borrow excavation. Its initial operation pre-dated Federal and State regulations governing waste disposal. The LCID Landfill has been operated as a controlled repository for C&D debris as well as for land clearing and inert debris since its permitting under NCDENR Permit No. 26C on August 28, 1987. From February 1993 to date of closure, C&D debris was diverted to the Longstreet Road Sanitary Landfill, and only LCID has been accepted at the LCID Landfill site. It is presumed that asbestos materials are disposed of in this landfill. Cooleyconch Mountain is the prominent terrain feature west of the main post. The LCID Landfill site is 1.5 miles west of the Longstreet Road municipal solid waste D R A F T 3 landfill (MSWLF) (closed January 1, 1998) and 200 yards northwest of the Lamont Road C&D Landfill. The area adjacent and east of the LCID Landfill has been excavated to be used as a borrow pit for sandy fill material. To the south of the LCID Landfill, in the C&D Landfill site, petroleum contaminated soils have been spread, dried, and stored for subsequent removal. To the east of the LCID Landfill, petroleum contaminated sludge has been stored in earthen impoundments for subsequent removal. The LCID Landfill drains north to Cypress Creek, which intersects the Little River a mile upstream of the Fort Bragg Water Plant intake. 1.4 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. 1.5 Previous Investigation and Results Several sampling events have been conducted at the landfills. 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 November of 2015 for Lamont Landfill, was conducted by the USACE, Savannah District. Low levels of Appendix I VOCs and metals were detected. All of the detections were below their respective NC2L standards and according to the statistical analysis there was no evidence that showed an increasing contaminant concentration trend. D R A F T 4 Between the May 2015 and the November 2015 sampling event USACE crews abandoned monitoring well LMW-4. During this effort monitoring well LMW-4R was unintentionally abandoned due to a labelling error on the protective cover. On November 20, 2015, LMW-4 was correctly abandoned and on December 9, 2015 a replacement well for the original LMW-4R was reinstalled. METHODS 1.6 Methane Monitoring Methane monitoring was performed at 16 locations around the Lamont landfill. The monitoring included measuring levels of methane, carbon dioxide, hydrogen sulfide and oxygen at each location. Results of the monitoring are summarized in Table 1 and are also presented on Figure 3. 1.7 Water-Level Gauging During this sampling event, USACE personnel measured the water levels in 13 monitoring wells. Observed 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 Lamont Landfill is towards the west-northwest. 1.8 Groundwater Sampling The groundwater sampling was conducted in accordance with the SAP for the Lamont Road LCID and C&D Landfills (NCDENR Landfill Permits # 26G and #26-08 dated April 2005, which have been updated to reflect the most recent SAP). Groundwater samples were collected from 13 wells. 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. The measurements are summarized in Table 3. D R A F T 5 Groundwater samples were collected using a low-flow purge method with either a bladder pump or a peristaltic 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 or peristaltic pump at a rate of 500 ml/min or less. 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 Celcius, pH readings within 0.1 Standard Units (SU), ORP values within a range of 10 milivolts (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 Table 4 and on Figure 5. The groundwater sampling field data logs are presented in Appendix A. D R A F T 6 1.9 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. ANALYTICAL RESULTS AND STATISTICAL ANALYSIS 1.10 Analytical Data Summary Groundwater samples collected in May 2016 were analyzed for Appendix I VOCs and metals. The summary of detections of the COCs is presented in Table 4. 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. 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). The analytical data of the May 2016 sampling event indicate that some VOCs were detected at low levels. One sampling locations had detections exceeding the NC2L standards: well LMW-7R (Table 4). The analytical results for the well is shown below: • Well LMW-7R One compound was detected above the 2L standard as listed below: Compound 2L Concentration Selenium 20 µg/L 24 µg/L No other constituents were above their 2L standards. D R A F T 7 1.11 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. If the fraction of non-detects exceeded 90%, then the Non-Parametric Prediction Limit was applied. For these tests to be sufficiently sensitive, the sample size for any group must be at least 4. A Kruskal-Wallis Test can be used in any situation that the parametric analysis of variance can be used. This test computes the H-statistic, adjusts it for ties, and compares it to the appropriate chi-square critical value. If the H-statistic is less than the critical value, the null-hypothesis is accepted, and it is concluded that there are no differences between median background and compliance well concentrations. If the H-statistic is greater than the critical value, it is concluded that at least one pair of well groups is statistically different. However, the Kruskal-Wallis test is prone to false positives. Therefore, additional statistical analyses were used to determine the validity of the positive results. Intra-well comparisons of data from a single well to previous data from the same well were performed to determine 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 statistical analysis indicate possible SSIs for several analytes that could not be confirmed. D R A F T 8 1.12 Methane Monitoring Results The methane levels were measured at 16 at Lamont Landfill. The results of the monitoring are summarized in Table 1 and are also presented on Figure 3. One methane monitoring well, GP-12, contained a high level of methane (> 5% methane by volume). Methane was detected at a concentration of 5.1% by volume at this location. In response to the exceedance monitoring frequency has been increased to a monthly schedule until methane levels decrease below 5% methane by volume, stabilizes or an increasing trend is established. 2.0 CONCLUSIONS AND RECOMMENATIONS The annual monitoring program consists of two sampling events conducted six months apart. This was the May 2016 sampling event for groundwater and methane monitoring performed by the USACE, Savannah District. It was the N=32 sampling event for the Lamont Road Landfills. Low levels of Appendix I VOCs and metals were detected. Well LMW-7R contained selenium above the NC2L standard. No other constituents were above their 2L standards. According to the Statistical Analysis of groundwater Data (Appendix C), there is no evidence of an upward trend in constituent concentrations. The statistical findings at the Lamont Road Landfill demonstrated that any statistical abnormalities were due to natural variation in the results. Long-term monitoring should continue at the Lamont Road Landfill because it is still an active site and NC Solid Waste Regulations require it. The methane levels were measured at 16 locations around Lamont landfill. One methane monitoring well contained methane at a concentration above 5% by volume, GP-12 (5.1%). In response to the exceedance methane monitoring has been increased to a monthly schedule at this location. It is recommended that monthly monitoring be continued until the concentration of methane decreases below 5% by volume, stabilizes or an increasing trend is established.

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 05/12/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 1.5 C. METALS (ICPMS) Samples LMW-8-5-16 (680-125208-1), LMW-4R-5-16 (680-125208-2), LMW-15R-5-16 (680-125208-3), LMW-14R-5-16 (680-125208-4), LMW-7R-5-16 (680-125208-5) and LMW-10-5-16 (680-125208-6) were analyzed for Metals (ICPMS) in accordance with EPA SW-846 Method 6020A. The samples were prepared on 05/15/2016 and analyzed on 05/20/2016 and 05/22/2016. Selenium was detected in method blank MB 680-433402/1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. ANIONS BY ION CHROMATOGRAPHY (48 HOUR) Samples LMW-8-5-16 (680-125208-1), LMW-4R-5-16 (680-125208-2), LMW-15R-5-16 (680-125208-3), LMW-14R-5-16 (680-125208-4), LMW-7R-5-16 (680-125208-5) and LMW-10-5-16 (680-125208-6) were analyzed for Anions by Ion Chromatography (48 Hour) in accordance with EPA Method 300.0. The samples were analyzed on 05/13/2016. The following samples were received with less than one shift (8 hours) remaining on a test with a holding time of 48 hours or less. As such, the laboratory had insufficient time remaining to perform the analysis within holding time: LMW-8-5-16 (680-125208-1) and LMW-4R-5-16 (680-125208-2). 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 05/13/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 0.4 C. METALS (ICPMS) Samples LMW-35-5-16 (680-125217-1), LMW-3-5-16 (680-125217-2), DUP-1-5-16 (680-125217-3), LMW-6-5-16 (680-125217-4) and BLK-1-5-16 (680-125217-5) were analyzed for Metals (ICPMS) in accordance with EPA SW-846 Method 6020A. The samples were prepared on 05/15/2016 and analyzed on 05/20/2016 and 05/22/2016. Selenium was detected in method blank MB 680-433402/1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. ANIONS BY ION CHROMATOGRAPHY (48 HOUR) Samples LMW-35-5-16 (680-125217-1), LMW-3-5-16 (680-125217-2), DUP-1-5-16 (680-125217-3), LMW-6-5-16 (680-125217-4) and BLK-1-5-16 (680-125217-5) were analyzed for Anions by Ion Chromatography (48 Hour) in accordance with EPA Method 300.0. The samples were analyzed on 05/13/2016. Sample LMW-6-5-16 (680-125217-4)[5X] required dilution prior to analysis. The reporting limits have been adjusted accordingly. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

The samples were analyzed on 05/23/2016 and 05/24/2016. Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with 680-434514. The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical batch 680-434550 recovered outside control limits for the following analytes: Isobutyl Alcohol. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. The following analyte recovered outside control limits for the LCSD associated with 680-434550: 4-Methyl-2-pentanone. This is not indicative of a systematic control problem because these were random marginal exceedances. Qualified results have been reported No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
