INTRODUCTION AH/BC Navy JV, LLC (AH/BC) provided groundwater, surface water, and leachate sampling services at the Subtitle D Municipal Solid Waste Landfill (MSWLF) facility at Marine Corps Base Camp Lejeune (MCB CAMLEJ). This project was completed under Naval Facilities Engineering Command (NAVFAC) Contract N62470-14-D- 9022, Delivery Order 0014. The Subtitle D landfill facility is located on Piney Green Road, and a general layout of the facility is provided in Figure 1-1. This report presents the results for the second biannual detection monitoring event for calendar year (CY) 2015. The North Carolina Solid Waste Management Rules (SWMR) require the MSWLF to monitor the groundwater using two types of monitoring wells (MW); background and compliance wells. Wells installed hydraulically up-gradient from the MSWLF are called background wells, and wells installed hydraulically down-gradient from the background wells are referred to as compliance wells. Currently, there are three (3) background wells and thirteen (13) compliance wells in the monitoring program at the MSWLF. Historically, chloroform had been detected at chronic concentrations in monitoring well MW-4 during earlier sampling events. For this reason, the MSWLF had begun assessment monitoring in accordance with 15A North Carolina Administrative Code (NCAC) 13B.1634 rules as directed by the North Carolina Department of Environmental Quality (NCDEQ). MCB CAMLEJ had then conducted a limited investigation for chloroform around MW-4. Upon completion of that investigation, NCDEQ had allowed the MSWLF to return to a detection monitoring regime. During each sampling event, samples are typically collected from three background monitoring wells (MW-1, MW-11 and MW-12), thirteen compliance wells (MW-2 through MW-10 and MW-14 through MW-17), two surface water sampling points (SW-1 and SW-2), and one sample point in the leachate collection system. During the October 2015 sampling period (October 27th and 28th) samples were collected from all Detection Monitoring Semiannual Report, Subtitle D Landfill MCB Camp Lejeune GROUNDWATER ELEVATION MAP Figure 1-1 DETECTION MONITORING SEMIANNUAL REPORT SECTION 1 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC INTRODUCTION AH/BC Navy JV, LLC Final, March 2016 119-14 1-2 sampling locations except for MW-16R. Compliance monitoring well MW-16R1 was not sampled due to its recent replacement; the well had not been outfitted with a dedicated sampling port/Teflon® tubing. This finding was shared with MCB CAMLEJ personnel during the sampling event. The dedicated sampling port/Teflon® tubing for MW-16R is scheduled to be installed prior to the next semi-annual sampling event. As required in the Detection Monitoring Program, all recovered monitoring well samples were analyzed for constituents listed in 40 Code of Federal Regulations (CFR) 258 Appendix I Constituents for Detection Monitoring (hereafter referred to as Appendix I). There are currently three cells at the MSWLF: both Phase I and Phase II cells are closed and the Phase III cell is currently receiving waste. The facility is expected to open additional waste receiving cells in the near future, which then will be known as the Phase IV and V Cells. 1 Former monitoring well MW-16 was recently abandoned and replaced with well MW-16R due to expan- sion activities on-site. DETECTION MONITORING SEMIANNUAL REPORT SECTION 2 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC GENERAL PHYSIOGRAPHY AH/BC Navy JV, LLC Final, March 2016 119-14 2-1 2. GENERAL PHYSIOGRAPHY The general background information presented in this section was originally presented in the June 2001 Detection Monitoring Report (DMR) prepared by S&ME (S&ME, 2001). This information has been modified for brevity and updated where necessary to reflect current conditions. 2.1 SITE TOPOGRAPHY The naturally occurring topographic relief of the local area surrounding the MSWLF is approximately 10 feet. The highest natural ground surface elevations, at 30 to 35 feet above Mean Sea Level (MSL) Datum, occur within the central portion of the site. In the vicinity of the Phase I and the Phase II cells, the ground surface slopes gently to the south, to an approximate elevation of 25 feet at the intersection of Shell Rock and Piney Green Roads. In the vicinity of the Phase III cell, the ground surface generally slopes to the north towards Wallace Creek. 2.2 SITE GEOLOGY Cretaceous-age sediments immediately overlying the basement rocks are divided into undifferentiated units identified as the Cape Fear, Middendorf (formerly Tuscaloosa), Black Creek, and Peedee Formations. Tertiary-age sediments deposited above the Cretaceous units include the Beaufort, Castle Hayne, and Belgrade Formations. Quaternary age surficial sediments consisting of sand, clay, gravel, and peat deposited in marine, fluvial, aeolian and lacustrine environments overlie the Tertiary units. Prior to commissioning new monitoring wells, soil borings were advanced into the Quaternary deposits to a depth of approximately 30 feet within the area of the MSWLF for the purposes of developing a stratigraphic profile. DETECTION MONITORING SEMIANNUAL REPORT SECTION 2 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC GENERAL PHYSIOGRAPHY AH/BC Navy JV, LLC Final, March 2016 119-14 2-2 2.3 SITE HYDROLOGY Surficial groundwater flow patterns in the vicinity of the MSWLF have been evaluated through a series of shallow monitoring wells finished at depths of about 30 feet (or less) below ground surface (bgs). The depth to groundwater varies from less than two feet bgs in the vicinity of Bearhead Creek to approximately 16 to 18 feet bgs in better- drained portions of the site. The highest groundwater elevations may normally be observed within the central portions of the MSWLF site, notably within the vicinity of MW-1, MW-11 and MW-12. This area appears to indicate a groundwater divide between the Phase III cell and the more southern oriented Phase I and Phase II cells. 2.4 GROUNDWATER TABLE The depth to the groundwater table was measured in three background wells (MW-1, MW-11 and MW-12) and thirteen compliance wells (MW-2 through MW-10 and MW- 14 through MW-17) during the October 2015 sampling event. At that time, each well was examined for its general integrity, including protection from surface water inflow, well identification tag, vented cap, lock, and general well security2. Each well was opened and the depth to the water table was measured from the top of the polyvinyl chloride (PVC) well casing using an electronic water level/slope indicator. The water table elevation at each well was calculated by subtracting the depth to groundwater measurement from the surveyed elevation of the top of the casing. Table 2-1 provides groundwater measurements and groundwater elevation calculations for each of the monitoring wells measured during the October 2015 sampling event, as well as, the previous sampling event conducted in June 2015. A water table contour map was constructed using a geographic information systems (GIS) base map and plotting the groundwater elevations calculated for each monitoring well location. Groundwater potentiometric surface contours, which were determined from the static groundwater measurements collected during the October 2 Compliance location MW-16R was not sampled due to its recent replacement; the well had not been outfitted with a dedicated sampling port/Teflon® tubing. This finding was shared with MCB CAMLEJ personnel during the sampling event. The dedicated sampling port/Teflon® tubing for MW-16R is sched- uled to be installed prior to the next semi-annual sampling event.

As seen in previous monitoring reports, within the vicinity of the MSWLF, groundwater flow appears to be split along a drainage divide that approximately bifurcates the Phase II cell from the Phase III cell. Groundwater generally flows to the south-southwest towards Bearhead Creek and to the north-northeast towards Wallace Creek. 2.5 HYDRAULIC GRADIENT & GROUNDWATER FLOW VELOCITY CALCULATIONS The hydraulic gradients (i) between the background wells and each of the compliance wells were determined by calculating the vertical difference between the groundwater elevations observed at the background wells and each of the compliance wells and then dividing that result by the measured distance from the background wells to each corresponding compliance well. The following background wells were used for these calculations: MW-1 for Phase I wells, MW-12 for Phases II wells, and MW-11 for Phase III wells. Hydraulic gradients within the vicinity of the MSWLF are typically flat. Positive gradients during the October 2015 event ranged from 0.0003 to 0.0096 feet per foot. Groundwater velocities were then calculated by multiplying the hydraulic gradient (i) determined above by a previously determined hydraulic conductivity (k) constant and then dividing that result by the estimated effective porosity (n) of the aquifer. Calculated groundwater flow velocities are summarized in Table 2-1. Based on the calculations, groundwater flow velocities during the October 2015 sampling event in the Phase I cell ranged from approximately 87.3 feet per year between MW-1 and MW-6 to approximately 112.2 feet per year between MW-1 and MW-2. Groundwater flow velocities in the Phase II cell ranged from approximately -5.7 feet per year between MW-9 and MW-12 to approximately 68.7 feet per year between MW-7R and MW-12. Groundwater flow velocities in the Phase III cell ranged from approximately 62.0 feet per year between MW-11 and MW-17 to approximately 159.5 feet per year between MW-11 and MW-14. On average, water levels during the October 2015 sampling event were approximately 0.33 feet higher than measured during the June 2015 sampling event.

Bearhead Creek is located west of the site and is the only surface water body to directly receive drainage from the facility. Wallace Creek then flows westward into the New River. According to MCB CAMLEJ’s 2001 Discharge Monitoring Report (DMR), the central portion of the site (near MW-1) is poorly drained and was classified as a wetland area. Phase I and Phase II of the MSWLF drain to the south into Bearhead Creek. Phase III appears to drain towards the north (within the Wallace Creek basin). There are two surface water sample collection points located due south of the Phase I cell. These locations are indicated on Figures 1-1 and 2-1.

SAMPING AND ANALYSIS PROGRAM This section describes the procedures used for collecting the groundwater and surface water samples. In accordance with 15A NCAC 13B.1633, MCB CAMLEJ has conducted semiannual detection monitoring for Appendix I constituents at the MSWLF. During the October 2015 sampling event, all active monitoring wells were sampled and analyzed for all Appendix I constituents. All methods used for sampling are compliant with the NCDEQ Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling manual. 3.1 MONITORING WELL SAMPLING PROTOCOL Prior to collecting groundwater samples, the static water level (SWL) was measured using an electronic water level meter at each location. The height of the water column was then used to calculate the well volume for each well. Once the well volume was calculated, each well was purged using low-flow sampling techniques, which minimize hydraulic stresses on the aquifer during purging and sampling events. This technique also ensures the recovery of a representative water sample directly from the aquifer formation as opposed to the water column. A peristaltic pump was then attached to dedicated Teflon® tubing which had been previously installed in each of the monitoring wells. The pump was then activated to induce a low-flow condition in which groundwater begins to flow from the aquifer into the screened zone of the monitoring well. The pump was then adjusted such that the rate of discharge was balanced by the well’s rate of recovery. This rate of discharge subsequently results in a minimal drawdown of water levels within each monitoring well. Temperature, pH, specific conductivity (SC), dissolved oxygen (DO), and turbidity were field measured at five-minute intervals during well purging until temperature, pH, DETECTION MONITORING SEMIANNUAL REPORT SECTION 3 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC SAMPING AND ANALYSIS PROGRAM AH/BC Navy JV, LLC Final, March 2016 119-14 3-2 and SC stabilized, while turbidity and DO were within ±10% of the previous reading. Stabilization is defined by NCDEQ as a variance of no more than ±0.2 standard units (SU) pH, ±0.2° temperature, and ± 5.0% SC. Groundwater samples were collected as soon as the water quality parameters met the stabilized condition criteria. The above field measured parameters are discussed in the following sections and are summarized in Table 2-1. Additional field notes are provided in Appendix A of this report. 3.2 SURFACE WATER SAMPLING PROTOCOL Surface water samples were collected from two surface water collection points located along the banks of Bearhead Creek. The sample locations are shown in Figures 1-1 and 2-1. Surface water samples were collected with the NCDEQ approved “surface grab sample” technique3. 3.3 LEACHATE SAMPLING PROTOCOL Leachate samples are collected from the leachate collection system when possible. Samples are generally collected directly from a dedicated sample tap located on the side-slope of the Phase I Cell near well MW-3. During the October 2015 sampling event, a sample set was drawn from this tap. Leachate samples were collected with the NCDEQ approved grab sample technique. 3.4 SAMPLE HANDLING, TRANSPORTATION, AND ANALYSES After each sample was collected, the samples were labeled and placed in a shipping cooler containing ice. Once sampling was complete, the samples were repackaged with new/additional ice and prepared for shipment to Prism Laboratories, Inc., of Charlotte, North Carolina for analyses. All samples were properly logged on a Chain- of-Custody (COC) form which was included with the sample coolers. Once prepared, a COC seal was placed on the exterior of each shipping cooler’s lid and secured with 3 As detailed in Appendix E of the Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling manual.

DETECTION MONITORING SEMIANNUAL REPORT SECTION 4 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC QUALITY CONTROL SAMPLES AH/BC Navy JV, LLC Final, March 2016 119-14 4-1 4. QUALITY CONTROL SAMPLES Quality control samples are often used to demonstrate the adequacy of field decontamination procedures (equipment rinsate blanks), assess the potential for cross contamination during shipment of the sample containers from the laboratory to the field or back to the laboratory (trip blanks), and to evaluate the consistency of laboratory analytical processes (field duplicate samples). During the sampling event, laboratory-prepared trip blanks accompanied the samples and were analyzed for Appendix I volatile organic compounds (VOCs). No equipment was reused in the field or decontaminated; therefore no equipment rinsate blanks were collected. In order to verify the laboratory’s level of precision, a field duplicate (FD or “Dup”) sample was collected during the October 2015 sampling event. The analytical results of the blind duplicate sample agreed closely with its corresponding matched sample collected from well MW-3. The MW-3/”Dup” duplicate sample set had an absolute average relative percent difference of 5.7% for all parameters4. The analytical results of the duplicate sample (“Dup”) are provided within Appendix B of this report. 4 This appears to be a relatively high percentage of difference with respect to historical calculations. However, the large difference is attributed to how the lab reports metallic constituents. It has been noted that none of the current metals results in the MW-3/”Dup” pair were found to be above the North Carolina Solid Waste Section Limit (SWSL). As such, there is very little concern over the RPD value.

ANALYTICAL RESULTS The laboratory analytical reports and COC forms are included in Appendix B. The analytical results for the organic and inorganic compounds that were detected above the North Carolina Solid Waste Section Limit5 (SWSL) during the October 2015 sampling event are summarized in Table 5-1. Also included in Table 5-1 are results that were detected above the lab’s internal Method Detection Limit (MDL) but below the SWSL Reporting Limit (RL) if the constituent was detected above the SWSL in at least one other well. These values are typically associated with a “J” ‘flag’ to indicate that the data was estimated by the laboratory. However, in some instances, a “J” flag was not assigned to the result as the value was detected above the lab’s internal RL. Results of estimated values (“J” flagged) and results above the lab’s internal RL, but below the SWSL, were not included in the following sections as they do not exceed the SWSL. These types of results are not to be included in statistical evaluations as directed by NCDEQ. 5.1 GROUNDWATER SAMPLES During the October 2015 sampling event, one Appendix I organic compound was detected above the SWSL. Chloroform was detected above the SWSL (5 µg/L) in well MW-4 at a concentration of 6.1 µg/L. This concentration was below the 15A NCAC 2L Groundwater protection standard of 70 µg/L. Chloroform was not detected in any other wells. Three Appendix I inorganic compounds barium, chromium and zinc, were detected above the SWSL in four compliance wells and within one background well. Barium was detected above the SWSL (100 µg/L) in well MW-17 at a concentration of 150.0 µg/L. This concentration is below the 15A NCAC 2L groundwater protection standard 5 A complete list of SWSL concentrations managed by the NC Division of Waste Management is provid- ed through the following web address: http://portal.ncdenr.org/web/wm/sw/envmonitoringlist.

Barium was also detected at trace concentrations in all remaining wells; however, those values were below the SWSL. Chromium was detected above the SWSL and 15A NCAC 2L standard concentrations of 10 µg/L in well MW-7R at a concentration of 11.0 µg/L. Chromium was also detected at trace concentrations in all remaining wells; however, those values were also below the SWSL6. Zinc was detected above the SWSL (10 µg/L) in two compliance wells and within one background well. Compliance wells MW-8 and MW-10 had zinc concentrations of 80.0 µg/L and 33.0 µg/L, respectively. Zinc was also detected above the SWSL in background well MW-11 at a concentration of 130.0 µg/L. These zinc concentrations are below the 15A NCAC 2L standard of 1,000 µg/L for zinc in groundwater. Zinc was also detected below the SWSL in all remaining wells. However, those concentrations were “J” flagged. 5.2 SURFACE WATER SAMPLES Surface water samples SW-1 and SW-2 were analyzed for Appendix I constituents. There were no Appendix I constituents detected above the 15A NCAC 2B surface water quality standards during the October 2015 sampling event. 5.3 LEACHATE SAMPLES Leachate samples were collected during the October 2015 event. Barium, zinc, and 1,4-dichlorobenzene were each detected above their corresponding SWSL values (but not above their corresponding 15A NCAC 2L groundwater protection standards). Biochemical oxygen demand, chemical oxygen demand and turbidity were also detected; however, these constituents do not have corresponding SWSL values. A summary of analytical results is located in Appendix B of this report. 6 It was noted that chromium was detected in one of the laboratory’s internal quality control (QC) blanks at a concentration of 0.965 µg/L (slightly below the method reporting limit of 1.0 µg/L). Due to the order of magnitude difference between the QC results and what was detected in MW-7R (11.0 µg/L), it is likely that the 2L exceedance is valid. However, the QC sample results indicate a potential deficiency in the accuracy of the chromium results.

STATISTICAL ANALYSIS This section describes the statistical methods used to evaluate qualified analytical data. Qualified analytical data are classified as values that are free of Data Reporting Qualifiers (such as “J” or “L”) which are also above the North Carolina Solid Waste Section Limit (SWSL) quantitation limit for each analyte of interest. According to the Division of Waste Management: “…laboratory analytical results with estimated concentrations (J-flagged) should not be included in statistical analysis.” 7 Statistical analyses were performed on all qualified data which have been collected at the facility since December 1997. The objective of this statistical evaluation is to determine whether indications of pollutants in compliance wells have or have not significantly increased over that of the background well (inter-well changes) or increased relative to their own water qualities (intra-well changes). 6.1 METHODS AH/BC has evaluated the historical data using statistical procedures outlined in Statistical Analyses of Groundwater Monitoring Data at RCRA Facilities, Unified Final Guidance (March 2009). Statistical analyses were performed only on qualified data where analytic concentrations were detected above their corresponding SWSL quantitation limits. This section provides a brief discussion of the general steps followed in the statistical analysis. The objective of this statistical evaluation is to determine whether indications of pollutants in compliance wells have or have not significantly increased over that of the background well (inter-well changes) or increased relative to their own historical water qualities (intra-well changes). Statistical evaluations were conducted using ChemStat 7 As confirmed by Ervin Lane, Compliance Hydrogeologist, NC Department of Environment and Natural Resources on November 22, 2010.

These statistical parameters include the sample minimum, maximum, mean, and standard deviation. Additionally, the percentage of non-detects was computed, and statistical outliers (for normal or transformed data sets) were identified. Conditions of each data set’s numerical distribution were evaluated in order to deter- mine which statistical method was most appropriate. Three conditions were considered in order to determine the appropriate method: normality, variance, and independence. The percentage of non-detects is also taken into consideration. As concentration data inherently belong to a one-tailed distribution system, contaminant parameters tend to be positively skewed from zero-concentration towards a higher concentration. Most groundwater quality data follow normal or log-normal distribution patterns. Data sets that are normally distributed are analyzed using parametric statistical procedures. Data sets that are non-normal or un-transformable require non- parametric analysis procedures. Additionally, data sets with a high percentage of non- detects also require non-parametric analysis methods. A summary of the data preparation results is provided in Table 6-1. 6.2.1 Normality The quality of results from statistical tests (based on the assumption of normality) be- comes questionable when data does not follow the normal model of distribution. The first level of method assessment is to determine if each data set follows the normal (Gaussian) model of distribution. Data sets with greater than 50 samples utilize the Shapiro-Francia test to determine normality (this method was used for this report). For data sets with less than 50 samples, the Shapiro-Wilks test is used.

This is critical as the tails of a data set’s distribution often depart from a normal distribution. When normality tests initially reveal the condition of non-normality, a redistribution-transformation of the data set is attempted. Transformed data sets are reevaluated for normality. If the condition of normality is met, the data set will remain transformed. If the condition of non-normality is present after transformation, the data set is returned to its original form and the condition of non-normality is considered valid. All data generated from this sampling event as well as every preceding sampling event (from both the up-gradient and down-gradient wells) were used in the evaluation of normality. 6.2.2 Variance Many statistical tests are based on the assumption of equal variance among data sets. Each data set’s “spread” or “variance” is assessed in order to determine if the condition of equal variance between each data set exists. The power of parametric testing decreases with an increase in data variance. Therefore, non-parametric tests are utilized when the calculated variance of a data set exceeds a tabulated and acceptable level of variance. Variance of a data set may be evaluated graphically or through computation. The graphic method is qualitative and is only used for an initial approximation of variance or where the variance is assumed to be so small that further quantitative measurements are not required. The facilities data sets are evaluated quantitatively with ChemStat. The test of equal variance (homogeneity) compares the measured spread of a group to a tabulated spread at a specified significance level. Where the measured spread exceeds the accepted spread, the assumption that data are of equal variance is rejected and the choice of test type used in statistical analyses should reflect this finding. Where data is found to be normally distributed, the Bartlett’s test for equal variance may be used. Where data is found to have a non-normal distribution, the Levene’s test for equal variance is used. DETECTION MONITORING SEMIANNUAL REPORT SECTION 6 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC STATISTICAL ANALYSIS AH/BC Navy JV, LLC Final, March 2016 119-14 6-4 6.2.3 Dependence The condition of data set dependence is critical. Most statistical procedures are based on the assumption of data independence. The location of each well assures that the collected samples are physically independent in that the data generated, and ultimately the evaluation, will be independent as well. No formal test for dependence is required. 6.3 METHOD OF STATISTICAL EVALUATION The Environmental Protection Agency (EPA) issued a procedural manual called the Statistical Analysis of Ground-Water Monitoring Data at RCRA Facilities, Unified Final Guidance (March 2009). Within the Unified Final Guidance manual, in "Appendix B. - Historical Notes", a reference was made to the EPA's "Addendum to Interim Final Guidance" document stating that the "test of proportions" method was no longer recommended for data sets which have greater than 90% "non-detect" data. The EPA's updated guidance now recommends utilizing the "Poisson Prediction/Tolerance limit" method when working with data sets with greater than 90% "non-detect" results. Methods of statistical evaluation were chosen based on results from the data preparation procedure (refer to Section 6.2). During data preparation, it was revealed that the data could not be transformed and normalized. Also, the non-detect rate for this facility generally averages approximately 95% for constituents detected above the SWSL standard. The Poisson Prediction Limit method was utilized for bulk analysis where whole sample populations were identified to have “non-detect” rates of greater than 90% during the data preparation phase. Otherwise, the Non- Parametric Prediction limit test was used for inter-well comparisons/analysis. Supplemental intra-well prediction limit comparisons were utilized in the event that inter-well tests indicated that a statistically significant value was identified. Depending on each well’s single parameter non-detect rate, either the Poisson or the Non- Parametric Prediction limit method was used. DETECTION MONITORING SEMIANNUAL REPORT SECTION 6 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC STATISTICAL ANALYSIS AH/BC Navy JV, LLC Final, March 2016 119-14 6-5 Statistically significant concentrations (SSCs), and potential statistically significant increases (SSIs), were identified when the current data collected during the October 2015 sampling event exceeded its corresponding background prediction limit. 6.4 RESULTS The following subsections describe the results of the statistical evaluations. 6.4.1 Inter-well Statistical Evaluation Inter-well evaluations were performed if any constituent in any compliance well had a concentration above the NC SWSL standard. Three inorganic and one organic constituent required analysis as indicated in Table 5-1. Inter-well analyses were performed for each of the following constituents: chloroform, barium, chromium and zinc. Inter-well evaluations of the down-gradient locations identified one potential organic SSC in well MW-4 (for chloroform). Two potential inorganic SSCs were identified for the barium concentration in MW-17 and the chromium concentration in MW-7R. Current zinc concentrations were not found to be significant. See Table 6-2 for a summary of inter-well testing results. 6.4.2 Intra-well Statistical Evaluation Intra-well evaluations were performed on constituents that were identified as potential SSCs during inter-well bulk analysis. With respect to inorganic constituents, the potential inter-well SSC identified for the chromium concentration in MW-7R was confirmed as a SSC through intra-well analysis. Further, the chloroform concentration in MW-4 and the barium concentration in MW-7R were found not to be valid intra-well SSCs. See Table 6-3 for a summary of intra-well testing results. 6.4.3 NCAC 2L/2B Exceedances One 15A NCAC 2L groundwater water protection standard exceedance was encountered during the October 2015 sampling event. The current chromium concentration of 11.0 µg/L in MW-7R was above the 2L standard of 10.0 µg/L.

Statistical evaluations can also be subject to additional non-numeric interpretations. Constituents that may be identified as potential SSCs may not be relevant in the context of the regulations if the detected value is below published quantification limits. In this regard, qualifying any concentration that is detected below the SWSL concentration as a SSC would be erroneous, as the validity of the result is in question (i.e., the detected parameter would be below the quantification threshold established by the State of North Carolina). In these cases, constituents identified in section 6.4 as potential SSCs must be compared against current quantification limits in order to establish the validity of the statistical results. During the October 2015 sampling event, this type of data evaluation was not required. A SSI may be identified if two SSCs are identified in series from one sampling event to another indicating an increasing trend. The one current intra-well SSC identified during the current analysis was not preceded by a SSC. As such no SSIs were identified as a result of the October 2015 sampling event. DETECTION MONITORING SEMIANNUAL REPORT SECTION 7 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC SUMMARY AH/BC Navy JV, LLC Final, March 2016 119-14 7-1 7. SUMMARY Samples were collected from three background wells, thirteen compliance wells and two surface water collection points during the October 2015 sampling event. Samples were also collected from the facility’s leachate collection system. Groundwater and surface water samples were analyzed for all Appendix I constituents. Statistical evaluations were then completed for constituents reported above the SWSL quantification standard. 7.1 GROUNDWATER SAMPLES One organic and two inorganic SSCs were initially identified through inter-well analysis based on data collected during the October 2015 sampling event. Intra-well evaluation of the two inter-well SSCs resulted in the identification of one intra-well SSC; chromium in well MW-7R. Based on the results of the statistical evaluations, the following observations can be made:  The current concentration of barium in MW-17 (150 µg/L) is significantly lower than the 15A NCAC 2L groundwater protection standard of 700 µg/L. The current concentration of barium in MW-17 was not confirmed to be a SSC through intra-well analysis.  The current concentration of chloroform in MW-4 (6.1 µg/L) was not confirmed to be a SSC through both inter and intra-well analysis. The current concentration continues to remain significantly lower than the 15A NCAC 2L groundwater protection standard of 70 µg/L for chloroform.  The current concentration of chromium in MW-7R (11.0 µg/L) was confirmed to be a SSC through both inter and intra-well analysis. The current concentration also exceeds the 15A NCAC 2L groundwater protection standard of 10 µg/L for chromium in groundwater.  The current zinc concentrations in wells MW-8 (80 µg/L) and MW-10 (33 µg/L) were not found to be SSCs through intra-well analysis. In addition, the current concentrations are significantly lower than the 15A NCAC 2L groundwater protection standard of 1,000 µg/L for zinc in groundwater.

There were no Appendix I constituents detected above the 15A NCAC 2B surface water quality standards during the October 2015 sampling event. 7.3 LEACHATE SAMPLE Leachate samples were collected during the October 2015 event. Barium, zinc, and 1,4-dichlorobenzene were each detected above their corresponding SWSL values (but not above their corresponding 15A NCAC 2L groundwater protection standards). Biochemical oxygen demand, chemical oxygen demand and turbidity were also detected; however, these constituents do not have corresponding SWSL values. 7.4 CONCLUSION Several Appendix I constituents were detected above the SWSL during the October 2015 sampling event. One Appendix I constituent was detected above its corresponding 15A NCAC 2L groundwater protection standards; chromium in well MW-7R. Constituents that were detected above the SWSL and/or 15A NCAC 2L groundwater protection standards are summarized below: Well MW-4 Chloroform was detected above the SWSL standard (but below the 15A NCAC 2L standard) at a concentration of 6.1 µg/L. This current concentration was not found to be a SSC or SSI through inter and intra-well analyses. Additionally, the current concentration remains below the historical mean concentration. Well MW-7R Chromium was detected above the SWSL standard at a concentration of 11.0 µg/L. This current concentration was found to be a SSC through inter and intra-well analyses. Additionally, the current concentration also exceeds the 15A NCAC 2L DETECTION MONITORING SEMIANNUAL REPORT SECTION 7 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC SUMMARY AH/BC Navy JV, LLC Final, March 2016 119-14 7-3 groundwater protection standard of 10.0 µg/L. This 2L exceedance is reported by MCB CAMLEJ to the state by means of this document and electronic data delivery. Well MW-8 Zinc was detected above the SWSL at a concentration of 80.0 µg/L. This concentration was not determined to be a SSC or SSI through inter and intra-well analyses. Additionally, the current concentration is approximately only 10% of the 15A NCAC 2L protection standard of 1,000 µg/L. Well MW-10 Zinc was detected above the SWSL at a concentration of 33.0 µg/L. This concentration was not determined to be a SSC or SSI through inter and intra-well analyses. Additionally, the current concentration is approximately 3% of the 15A NCAC 2L protection standard of 1,000 µg/L. Well MW-11 Zinc was detected above the SWSL at a concentration of 130.0 µg/L. Statistical evaluation of this concentration was not performed as this well is used to establish background concentrations used for statistical purposes. Despite the detection, the current concentration is significantly lower than the 15A NCAC 2L protection standard of 1,000 µg/L. Well MW-17 Barium was detected above the SWSL at a concentration of 150.0 µg/L. The current concentration was not confirmed as a SSC/SSI through inter and intra-well analyses. Additionally, the current concentration is approximately 22% of the 15A NCAC 2L protection standard of 700 µg/L. DETECTION MONITORING SEMIANNUAL REPORT SECTION 7 SUBTITLE D LANDFILL, MCB CAMP LEJEUNE, NC SUMMARY AH/BC Navy JV, LLC Final, March 2016 119-14 7-4 General Guidance By regulation, MCB CAMLEJ is required to declare the following 15A NCAC 2L exceedances identified during the October 2015 sampling event. No SSI concentrations were identified during this sampling event:  MW-7R: 15A NCAC 2L chromium exceedance, 11.0 µg/L According to the NCAC Corrective Action Flowchart (Figure 7-1) the State may or may not ask MCB CAMLEJ to proceed with one of the following options in response to the reported 2L exceedance: 1. Sample all wells for Appendix II constituents; 2. Resample for detected Appendix II constituents and all Appendix I constitu- ents Semi-annually; 3. Semi-annual monitoring for all Appendix II constituents; 4. Establish groundwater protection standards. Dependent upon the outcome of any additional sampling, the facility may be eligible to retain its current Modi- fied Assessment Monitoring program.
