BROOKHAVEN NATIONAL LABORATORY 2009 ENVIRONMENTAL MONITORING REPORT CURRENT AND FORMER LANDFILL AREAS Prepared by Brookhaven National Laboratory Environmental Protection Division Upton, New York March 11, 2010 BROOKHAVEN NATIONAL LABORATOR 2009 ENVIRONMENTAL MONITORING REPORT CURRENT AND FORMER LANDFILL AREAS Executive Summary This report documents the Operations and Maintenance activities undertaken during the calendar year 2009 for the Current Landfill (AOC 3) and the Former Landfill Areas (Former Landfill AOC 2A, Interim Landfill AOC 2D, and Slit Trench AOC 2E). Brookhaven National Laboratory is responsible for performing this work to comply with the post-closure O&M requirements specified in 6 New York State Code of Rules and Regulations (NYCRR) Part 360, Solid Waste Management Facilities, effective December 31, 1988. The landfill caps are functioning as designed and the 2009 results are consistent with results from previous years. GROUNDWATER QUALITY The groundwater quality at both the Current and Former Landfill Areas remains relatively unchanged from 2008. Volatile organic compounds (VOCs) and metals continue to be detected downgradient of the Current Landfill. The most prevalent VOCs detected above standards are chloroethane and benzene, at maximum concentrations of 27 μg/L and 2 μg/L, respectively. As with previous years, iron, manganese, and arsenic were detected downgradient from the Current Landfill at concentrations above applicable standards. Concentrations of these metals were similar to those detected in 2008. Maximum concentrations of iron, manganese, and arsenic in downgradient wells were 68,900 μg/L, 6,650 μg/L, and 23 μg/L, respectively. These results are an indicator of continued low level leachate generation at this landfill. Concentrations of parameters detected in wells downgradient of the Former Landfill Area do not indicate the presence of leachate. VOCs were not detected above standards in Former Landfill Area monitoring wells. Leachate indicator parameters and metals concentrations were generally the same when comparing downgradient monitoring wells to upgradient monitoring wells. The groundwater monitoring well network and sampling frequencies for both the Current Landfill and the Former Landfill are adequate at this time. SOIL-GAS MONITORING Soil-gas monitoring at the Current Landfill indicates that decomposition is still occurring. However, as with prior years, there is no indication that the vapors are migrating beyond the monitoring well network. Therefore, there is no potential risk to the nearby National Weather Service building. Soilgas monitoring at the Former Landfill Area indicates that there are only minimal detects of hydrogen sulfide, with no detectable levels of methane present. The soil gas monitoring well networks are sufficient to monitor both landfill areas. MAINTENANCE AND REPAIR Monthly inspections and maintenance continued throughout 2009. To prevent ruts in the landfills caused by the weight of the lawn mowers and a significant amount of precipitation, the cutting of the grass only occurs when optimal soil conditions are evident. This pattern of vegetation control will continue. Small animal burrows were noted during the biannual LTRA inspections. Also vegetation was noted growing in the drainage channels. Work orders were placed to fill in the animal burrows and the vegetation was removed in June 2009. i TABLE OF CONTENTS Executive Summary………………………………………………………………………………..i 1.0

Brookhaven National Laboratory (BNL) is responsible for performing this work to comply with the post-closure O&M requirements specified in the 6 New York State Code of Rules and Regulations (6NYCRR) Part 360, Solid Waste Management Facilities, effective December 31, 1988. The details of the O&M programs are described in the Final Operations and Maintenance Manuals for the Current Landfill (CDM Federal, 1996a) and the Former Landfill Areas (CDM Federal, 1996b). The following are the primary objectives of the O&M program: Monitor the effectiveness of the impermeable caps in protecting groundwater quality; Monitor the potential generation and migration of soil-gas; and Maintain and monitor the various components of the closure system (landfill caps, drainage structure, and environmental monitoring systems). This is the fourteenth year of O&M for the Current Landfill, the thirteenth year for the Former Landfill and Slit Trench, and the twelfth year for the Interim Landfill. 1.1 Site Description and Project Background BNL is a 5,265-acre site located in central eastern Long Island, New York. The facility is a federally owned and funded international research and learning center managed, by Brookhaven Science Associates (BSA) under contract with the United States Department of Energy (DOE). On December 21, 1989, the site was placed on the United States Environmental Protection Agency’s (USEPA’s) National Priorities List (NPL), a ranking of hazardous waste sites compiled by the federal government as part of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Placing BNL on the NPL resulted in the establishment of a remediation-task list for T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 1 various locations around the facility. The site subsequently was divided into seven separate remediation work areas known as Operable Units (OU). The Current Landfill and Former Landfill Areas are located in OU I, near the south central portion of the BNL site (see Figure 1). Current Landfill. The Current Landfill consists of one unlined waste-cell that operated from the late 1960s until 1990 for disposing of waste generated at the Laboratory. An impermeable cap covering the cell was completed in November 1995. Additional information about the cap’s construction can be obtained from the Construction Certification Report for the Current Landfill (CDM Federal, 1996b). Following the installation of the cap, the post-closure groundwater-monitoring program was implemented in December 1996, in accordance with 6 NYCRR Part 360 Section 2.15, Solid Waste Management Facilities (effective December 31, 1988). Groundwater quality near the Current Landfill is monitored under the O&M program for a wide variety of volatile organic compounds (VOCs), metals, radiological, and water chemistry (landfill leachate) parameters. Monitoring in this vicinity was expanded in 1999 to include a wetland area adjacent to the landfill’s eastern boundary. This area, known as the Wooded Wetland area, is a twoacre wetland located between the Former Hazardous Waste Management Facility (HWMF) and the Current Landfill. The wetland receives surface runoff from the Current Landfill and usually is flooded during the spring/early summer and dry in late summer/fall. Monitoring of the Wooded Wetland area has been incorporated into the Current Landfill Monitoring Program and consists of sampling and analyzing surface water and sediment to evaluate the potential for leachate migrating into this area, as originally performed under the OU I Ecological Risk Assessment (CDM Federal, 1999). As required under 6 NYCRR Part 360, groundwater quality must be monitored for a minimum of five years, after which the permittee may request modification of the sampling and analysis requirements. In October 2001, BNL submitted the Five-Year Evaluation Report for the Current Landfill (BNL, 2001). This report assessed groundwater trends over the five years after capping, and proposed changes to the sampling program. These changes were implemented in CY02. In July 2006, BNL issued the Final Five-Year Review Report which discussed all remediation areas at the site. Review of the Current Landfill was included in this report. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 2 FormerLandfill Area The Former Landfill Area encompasses three closely located landfill units; the Former Landfill, the Slit Trench, and the Interim Landfill. The Former Landfill is an unlined wastedisposal area originally used by the United States Army in the 1940s. Waste disposal operations ceased in 1966, and the landfill was covered with soil. The Interim Landfill also is unlined, and was reportedly used for approximately one year between the time the Former Landfill was closed and the Current Landfill was opened. The Slit Trench is unlined as well, and is believed to have operated between 1960 and 1967 for disposal of construction and demolition debris (CDM Federal, 1996). The Former Landfill and Slit Trench were capped in November 1996 and the Interim Landfill was capped in October 1997. Additional information about the construction of the caps can be found in the Construction Certification Report for the Former Landfill (Roy F. Weston, 1997) and Construction Certification Report for the Interim Landfill Capping (PW Grosser, 1997). BNL started O&M activities in December 1996 at the Former Landfill and Slit Trench, and in November 1997 at the Interim Landfill. Under this O&M program, groundwater quality in downgradient wells in the vicinity of the Former Landfill is monitored for VOCs, metals, radionuclides, and landfill-leachate parameters. In March 2002, BNL submitted a Five-Year Evaluation Report for the Former Landfill (P.W. Grosser, 2002), which assessed trends in groundwater quality over the five-year period following capping and proposed changes to the sampling program. These changes were implemented in CY03. In July 2006, BNL issued the Final Five-Year Review Report which discussed all remediation areas at the site. Review of the Former Landfill Area was included in this report. 1.2 Overview of the Monitoring Program Groundwater Monitoring Data quality objectives for each of BNL’s groundwater monitoring programs are presented in the BNL Environmental Monitoring Plan (BNL, 2009). The design of the data collection network was optimized as part of the process. Such optimization continues annually as part of the O&M program and is based on the interpretation of new data as well as historical trends. The primary decision T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 3 identified for the landfill monitoring programs is “Are the controls effectively improving groundwater quality below and downgradient of the landfill?” Groundwater samples are collected from monitoring wells positioned upgradient and downgradient of each landfill area. Analytical data are reviewed, and determinations are made regarding the effectiveness of landfill controls. The additional monitoring programs for the landfill areas consists of: Soil-gas Monitoring. Measurements of methane, Lower Explosive Limit (LEL), and hydrogen sulfide are taken quarterly from monitoring locations surrounding the landfills to evaluate the movement of soil-gas from the landfills. Wooded Wetland Monitoring. Surface waters and sediments in the wooded wetland adjacent to the eastern boundary of the Current Landfill are sampled every two years to evaluate possible effects of landfill leachate on Tiger Salamander habitats. Samples were last collected in 2008 and are scheduled for collection again in 2010. Routine Visual Inspection, Maintenance, and Repair. Monthly inspections are performed to monitor the structural and/or operational status of the landfill caps, drainage structures, and environmental monitoring systems. Leachate Discharge. Visual inspections of the landfills are performed monthly to monitor for signs of leachate discharge. If observed, samples of the leachate are collected and analyzed. These activities are discussed in greater detail in Sections 2 through 5 of this report. Section 6 contains the conclusions and recommendations. References are included in Section 7. 2.0 GROUNDWATER MONITORING 2.1 Monitoring Well Networks 2.1.1 Current Landfill Since February 1996, groundwater quality at the Current Landfill has been monitored using ten downgradient wells and one background monitoring well. Figure 2 depicts the location of the T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 4 monitoring wells. Figure 3 shows the water table contours for this area in June 2009. The depths of the screen intervals for the Current Landfill wells are listed below. Well ID Screen Interval (ft BLS) Screen Zone 087-09* 24–34 Shallow Glacial 087-11 11–21 Shallow Glacial 087-23 25–40 Shallow Glacial 087-24 70–80 Intermediate 087-26 70–80 Intermediate 087-27 5–20 Shallow Glacial 088-109 6–21 Shallow Glacial 088-110 10–25 Shallow Glacial 088-21 5–20 Shallow Glacial 088-22 70–80 Intermediate 088-23 120–130 Deep Glacial BLS = Below Land Surface *Background well Screen zones were determined based on the following characteristics: Shallow Zone: typical water table within 10 ft of the screen zone. Intermediate Zone: typical water table between 10 ft and 100 ft above the screen zone. Deep Zone: typical water table >100 ft above the screen zone. 2.1.2 Former Landfill Since January 1997, groundwater quality at the Former Landfill area has been monitored using eight shallow monitoring wells (three background and five downgradient). The locations of the eight monitoring wells are presented in Figure 4. In addition, six wells, 106-20, 106-21, 106-43, 106-44, 106-45 and 106-64 were moved from the Chemical/Animal Holes project to the Former Landfill Area project. This move was made since the analyte of interest detected in these wells (strontium-90) originated from the Former Landfill. The direction of groundwater flow in the OU I area of the site is generally to the south-southeast. Figure 3 shows the June 2009 water table T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 5 contours for the area. The screen zones for Former Landfill Area wells are summarized below. Well ID Screen Interval (ft BLS) Screen Zone 086-42* 65–75 Intermediate 086-72* 41.5–56.5 Shallow Glacial 087-22* 43–53 Shallow Glacial 097-17 29–39 Shallow Glacial 097-64 29–44 Shallow Glacial 097-277 40–55 Shallow Glacial 106-02 55–65 Intermediate 106-30 29–44 Shallow Glacial 106-20 85-95 Intermediate 106-21 55-65 Shallow Glacial 106-43 43-53 Shallow Glacial 106-44 44-54 Shallow Glacial 106-45 44-55 Shallow Glacial 106-64 30-40 Shallow Glacial BLS = Below Land Surface *Background well Screen zones were determined based on the following characteristics: 2.1.3 Shallow Zone: typical water table within 10 ft of the screen zone. Intermediate Zone: typical water table between 10 ft and 100 ft above the screen zone. Sampling Frequency and Analytical Parameters Monitoring wells at the Current Landfill were sampled in 2009 during the following periods: Sampling Event Sampling Dates Round 1 March 12 - 13 Round 2 June 4 Round 3 August 26 Round 4 December 1 Based on the recommendation in the 2008 Landfill Report, the sampling frequency was reduced from quarterly to semiannual for all organic and inorganic parameters. The routine sampling schedule was changed to collect samples during the 2nd and 4th quarters. Since the recommendation was approved after the 1st quarter round was collected, there were three complete sampling rounds collected during 2009. As of 2010, only 2 rounds will be collected. As per the schedule listed on T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 6 Table 1, during the August round, only well 088-109 was sampled. Monitoring wells at the Former Landfill were sampled in 2009 during the following periods: Sampling Event Sampling Dates Round 1 June 3 Round 2 December 2-3 As per the schedule listed on Table 1, during the June round, only wells 106-20, 106-21, 106-43, 106-44, 106-45, and 106-64 were sampled. R&C Formation, Ltd. of Bellmore, New York conducted the groundwater sampling, and Test America, St. Louis Missouri analyzed the samples. See Table 1 for a summary of analyses performed, by well and sampling round. 2.1.4 Quality Assurance / Quality Control The groundwater samples were collected and analyzed in accordance with strict quality assurance, quality control (QA/QC) requirements as described in the BNL Groundwater Monitoring Program Quality Assurance Project Plan (QAPP) (BNL, 1999). The analytical results for groundwater samples collected during 2009 satisfied the data-quality objectives. The sampling team personnel are responsible for assuring that a master calibration/maintenance log is maintained for each fieldmeasuring device (e.g., pH conductivity, turbidity meters). The sample coordinator provided a calibration/maintenance log for equipment supplied to the contractor’s sampling teams. The analytical results of samples collected for the Current and Former Landfill Area projects underwent data verification, using BNL standard operating procedures EM-SOP-203, Chemical Data Verification, and EM-SOP-204, Radiochemical Data Verification. These procedures are designed to verify the accuracy and/or completeness of analytical data. The data verification process is implemented to detect the most common analytical problems that affect the quality of the results. To accomplish this task, QA/QC items such as the following were checked: holding times, matrix spikes, laboratory and field blanks, and field logs. If items are found that can affect the use and interpretation of the data, they are either corrected, as in the case of unreadable information on the T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 7 field logs, or the data are “qualified,” as in the case of contamination of the blanks or violations of the holding time. Guidance on the collection of QA/QC samples is contained in the QAPP, and in BNL procedure EM-SOP-200, “Collection and Frequency of Field Quality Control Samples.” The QA/QC samples collected included trip blanks, field blanks, matrix spike/matrix spike duplicate (MS/MSDs), and blind duplicates. Trip blanks were analyzed for aqueous VOCs only. One trip blank was shipped to the analytical laboratory with each set of samples submitted for VOC analyses. One duplicate sample was collected from the Current Landfill during the second and fourth quarters, and one duplicate sample was collected during the quarter from the Former Landfill. No errors were detected in the duplicate analyses. MS/MSD samples were collected at the same frequency as the duplicates. Chloromethane and bromomethane were detected in various method and trip blanks during 2009. Sample results with concentrations of these compounds within five times the associated blank value were declared non-detect. The amount of qualified data was within acceptable limits and did not adversely impact the review of the groundwater quality. 2.2 Landfill Groundwater Monitoring Results This section summarizes the results for VOCs, metals, water-chemistry parameters, and radionuclides detected for both the Current Landfill and Former Landfill Area in CY09. The historical trends in concentrations of key contaminants are assessed and shown graphically in Figures 5 through 12. Summary tables of all 2009 landfill groundwater data are presented in Tables 2 through 10. Detections that exceed groundwater standards are in bold text. The tables include groundwater standards, laboratory results, minimum detection limits, and laboratory data qualifiers. The groundwater standards used for evaluating groundwater data include those contained in the NYSDEC Ambient Water Quality Standards and Guidance Values (June 1998, with addendums April 2000 and June 2004). Groundwater standards for radiological compounds were supplemented with New York State Department of Health’s (NYSDOH’s) standards for drinking water when a NYSDEC groundwater standard was not available. When there were no groundwater standards for a T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 8 radiological compound, a Groundwater Screening Level was used. This value is based on a dose equivalent of 4 mrem/year and was calculated as 4% of the DOE Derived Concentration Guides (DCG) (DOE Order 5400.5) for the isotope of concern. These values are listed under the “groundwater standards” column in the summary tables and annotated where appropriate. Laboratory results that exceed the lower of the groundwater standards or the Selected Cleanup Goals listed in the ROD are highlighted in the data summary tables to facilitate review of the information. The laboratory data qualifiers included in the tables vary for the different analyses. Explanations for the data qualifiers are included in the notes in each table. Complete 2009 laboratory data reports, chain of custody forms, and well-sampling logs for both landfills are archived and available upon request. In addition, analytical results are stored in the BNL Environmental Information Management System (EIMS) database. 2.2.1 Current Landfill 2.2.1.1 Volatile Organic Compounds (VOCs) Benzene, and/or chloroethane, were detected above their respective groundwater standards in three of the 10 downgradient monitoring wells during 2009 (Table 2). 1,1-Dichloroethane was also detected above the groundwater standard in one well. These VOCs have historically been the primary groundwater contaminants detected downgradient of the Current Landfill. No other VOCs were detected above groundwater standards during 2009. Figure 5 plots the concentration trends of total VOCs (TVOC), benzene, and chloroethane. As shown, VOCs remained relatively stable at low concentrations. Overall, the trend plots also show a distinct decrease in VOC concentrations from the high concentrations seen prior to the installation of the cap. This reflects the positive effects of the capping on the groundwater quality downgradient. Several chloroethane results were slightly elevated during the 2008 monitoring events in wells 088109, 088-110, and 087-11. The chloroethane concentrations for samples collected during 2009 have returned to previous levels. Benzene exceeded the 1 μg/L standard in well 087-11. Chloroethane exceeded the 5 μg/L standard in wells 087-11, 087-23, and 088-109. The maximum chloroethane concentration was 26.9 μg/L in well T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 9 088-109; which is a decrease from the high of 80.8 μg /L in 2008. Benzene was detected at a maximum of 2 μg/L in well 087-11. There have been no detections of VOCs exceeding groundwater standards in wells 087-24, 088-22, and 088-23 since 1998. These downgradient wells are screened in the mid to deep Upper Glacial Aquifer as perimeter wells to monitor the vertical extent of contamination from the Current Landfill. 2.2.1.2 Water Chemistry Parameters Groundwater samples near the Current Landfill were analyzed for ammonia, total kjeldahl nitrogen (TKN) cyanide, sulfate, nitrite, nitrate, total nitrogen, chloride, alkalinity, total dissolved solids (TDS or residue, nonfilterable), and total suspended solids (TSS or residue, filterable) during 2009 (Table 1). The results are provided in Table 3. Elevated levels of these parameters can be indicative of the presence of landfill leachate. During 2009, ammonia and chloride were the only water chemistry parameters detected above standards. Ammonia was detected above the standard of 2 mg/L, with exceedances in three downgradient wells (087-11, 087-27, and 088-110) during three sampling events, as shown in Table 3. The highest concentration of 7.03 mg/L was reported for well 088-110 in June. The levels of ammonia detected are consistent with historic data. Chloride was detected in one well above the standard of 250 mg/L. Well 088-21 had a concentration of chloride at 270 mg/L in March. The concentration decreased each subsequent round to a low of 72.7 mg/L in December. Figure 6 plots these trends. With the exception of well 088-21, the trends for downgradient wells show the low and stable nature of chloride concentrations in the vicinity of the Current Landfill. During 2009, all sulfate concentrations remained below the groundwater standard of 250 mg/L. The highest sulfate value reported for 2009 was detected in the December sample from monitoring well 088-110 at a concentration of 20.2 mg/L. This is consistent with historic background levels at the Current Landfill. Alkalinity, in the form of bicarbonate, is the concentration of anions available to neutralize acid, and is often used as an indicator of leachate contamination. The alkalinity in background well 087-09 ranged from 17.4 mg/L to 22.9 mg/L during 2009. The highest alkalinity concentration during 2009 T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 10 was detected in downgradient, shallow Glacial Aquifer well 087-11, at 192 mg/L in December. There is no groundwater standard for alkalinity. The concentration trends plotted in Figure 6 show an overall decrease in alkalinity following the capping of the landfill. Alkalinity levels in the background well remained stable during this period. Total dissolved solids and TSS results were similar to those from previous years. TDS and TSS concentrations in background well 087-09 ranged from 156 mg/L to 194 mg/L, and 7.1 mg/L to 10.4 mg/L, respectively. The maximum concentrations observed in downgradient wells were 565 mg/L and 70.8 mg/L of TDS and TSS, respectively. No water chemistry parameters have exceeded groundwater standards in downgradient wells 087-24, 088-22, and 088-23, since 1998. These wells are all screened in the mid to deep-Upper Glacial Aquifer to monitor the vertical extent of contamination from the Current Landfill. A comparison of downgradient and background wells shows that leachate continues to be generated from the Current Landfill, albeit at low concentrations. Decreasing trends in concentration indicate that the capping is effectively reducing the generation and migration of leachate. 2.2.1.3 Metals Historically, iron is detected consistently above groundwater standards in the majority of wells surrounding the landfill. Precipitated iron from the BNL Water Treatment Plant was disposed of at the Current Landfill during past operations. Concentrations in upgradient well 87-09 are still lower than in the downgradient wells, suggesting continued leachate migration from the landfill. During 2009, aluminum, antimony, chromium, iron, nickel, sodium, and thallium in the background well and antimony, arsenic, iron, manganese, and sodium, in downgradient wells were detected above their respective groundwater standards (Table 4). Iron in the downgradient wells peaked at a maximum of 68,900 μg/L in well 088-110 during March. In contrast to background concentrations, in well 87-09, iron ranged from 2,100 μg/L to 3,860 μg/L. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 11 Manganese ranged from 75.2 μg/L to 146 μg/L in background well 087-09, and up to 6,650 μg/L in the downgradient wells. Background sodium levels ranged from 32,800 to 52,900 μg/L; whereas downgradient levels reached a high of 181,000 μg/L. Arsenic was reported above the standard of 10 μg/L in wells 087-23 and 088-110 at a concentrations of 11.9 μg/L and 23.2 μg/L, respectively. Arsenic detections have historically been observed at similar levels in Current Landfill wells. Antimony was detected above the standard of 3 μg/L in downgradient wells 087-11, and 088-21 at concentrations ranging from 3.4 μg/L to 7.2 μg/L. Thallium was detected in background well, 087-09, above the standard of 0.5 μg/L ranging from 0.5 μg/L to 0.8 μg/L. Nickel and chromium were detected above the standard of 100 μg/L and 50 μg/L, respectively, in background well 087-09. However, neither was detected above standards in any of the downgradient wells. 2.2.1.4 Radionuclides No radionuclides were detected above groundwater standards during 2009 (Table 5). Strontium-90 (Sr-90), and tritium were the only radionuclides detected during 2009. Sr-90 was detected in wells 087-09 and 088-21 at concentrations of 1.28 pCi/L and 3.45 pCi/L, respectively, during December. These are well below the standard of 8 pCi/L. Tritium was detected significantly below the groundwater standard of 20,000 pCi/L with a maximum value of 622 pCi/L in well 087-11 (Figure 8). Tritium and Sr-90 concentrations have not exceeded groundwater standards in any wells since 1998. 2.2.2 Former Landfill 2.2.2.1 VOCs During 2009, there were no detections of VOCs above groundwater standards in wells in the Former Landfill Area (Table 6). The compounds consistently found in the Former Landfill Area monitoring wells include 1,1,1-trichloroethane, and chloroform. Chloroform was reported in several wells during the year at concentrations ranging from 0.27 μg/L to 2.1 μg/L, well below the groundwater standard of 7 μg/L. 1,1,1-Trichloroethane detections ranged from 0.3 μg/L to 1.9 μg/L. These concentrations are well below the standard of 5 μg/L. Figure 9 shows plots of the historical VOC detections for the Former Landfill Area monitoring wells. During 2009, VOCs were detected at the T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 12 Former Landfill Area in several wells, but only at trace concentrations, indicating that the cap on the landfill is operating as intended. 2.2.2.2 Water Chemistry Parameters Groundwater samples from monitoring wells in the Former Landfill Area were analyzed for sulfate, nitrite, nitrate, total nitrogen, chloride, alkalinity, TDS (TDS or residue, non-filterable) and TSS (TSS or residue, filterable). During 2009, none of the of water chemistry parameters exceeded applicable groundwater standards (Table 7). In general, all of the landfill leachate indicator parameter concentrations in the downgradient wells were indistinguishable from concentrations in the upgradient wells in 2009. These trends indicate that the landfill cap is effective. Sulfate concentrations ranged from 8.6 mg/L to 9.6 mg/L in the background wells, and from 5.7 mg/L to 23.7 mg/L in downgradient wells, significantly below the standard of 250 mg/L. Nitrogen in the form of nitrate (NO3), and chloride were consistently low with concentrations up to 1.2 mg/L and 38.4 mg/L, respectively in the background wells and concentrations up to 1.2 mg/L and 12.8 mg/L, respectively in the downgradient wells. The trends plotted in Figure 10 indicate chloride concentrations are stable over time. Alkalinity concentrations ranged from 5.5 mg/L to 33.2 mg/L in background wells and from 5 mg/L to 21.8 mg/L in downgradient wells. The trends plotted in Figure 10 demonstrate that the alkalinity concentrations in 2009 continue to be at background levels. TDS concentrations ranged from 32 mg/L to 146 mg/L in the background wells, and from 28 mg/L to 59 mg/L in the downgradient wells. TSS concentrations were nondetect in the background wells, and ranged from nondetect to 10.4 mg/L in the downgradient wells. TKN concentrations ranged from 0.05 mg/L to 0.09 mg/L in the background wells. TKN concentrations in the downgradient wells ranged from nondetect to 0.16 mg/L. 2.2.2.3 Metals The sampling results are summarized in Table 8, and concentration trend plots for iron are shown on Figure 11. Iron was the only metal detected that exceeded the groundwater standards in T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 13 downgradient wells during 2009. Downgradient well 106-02 had a concentration of 956 μg/L in December. This is above the standard of 300 μg/L. 2.2.2.4 Pesticides/PCBs There were no detections of pesticides or polychlorinated biphenyls (PCBs) during 2009. The sampling results are summarized in Table 9. 2.2.2.5 Radionuclides Tritium was not detected in any wells during 2009. Strontium-90 was detected in five wells in 2009 below the groundwater standard of 8 pCi/L. Detects ranged from 1.07 pCi/L to 4.62 pCi/L in well 106-44. The sampling results are summarized in Table 10, and concentration trend plots are shown on Figure 12. 3.0 WOODED WETLAND MONITORING Sampling at the Wooded Wetland is performed as part of the compliance monitoring for the Current Landfill. Prior to the capping of the Current Landfill, leachate was periodically observed in the wetland. The monitoring is focused on metal concentrations in the sediment and surface water to evaluate potential risks to the local Tiger Salamander population. Samples are collected every two years. Samples were last collected in 2008 and are scheduled for collection again in 2010. 4.0 SOIL-GAS MONITORING 4.1 Soil-gas Monitoring Networks Soil-gas readings were collected from wells surrounding the Current Landfill in March, July, November, and December 2009 and from the Former Landfill in March, July, and December 2009. For the Former Landfill, the soil-gas monitoring schedule was changed to collect samples during the 2nd and 4th quarters based on a recommendation in the 2008 Landfill Report. Since the recommendation was approved after the 1st quarter round was collected, there were three complete soil-gas rounds collected during 2009. Methane, lower explosive limit (LEL), and hydrogen sulfide were measured using a Landtec GA-90 (Serial # 690). The LEL for methane is 5.3% and the upper explosive limit (UEL) is 15%. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 14 4.1.1 Current Landfill Along the perimeter of the Current Landfill, 58 points were sampled for soil-gas, which includes four outpost soil-gas well clusters, GSGM-1 to GSGM-4, located along the south side of Brookhaven Avenue. The sampling points include 12 soil-gas well clusters consisting of three sampling intervals per cluster, and 11 soil-gas well couplets consisting of two sampling intervals per couplet. Table 11 describes each soil-gas well. Their locations are illustrated on Figure 13. 4.1.2 Former Landfill Area Twenty-four sampling points were monitored for the Former Landfill Area. These points include 12 well couplets consisting of two sampling points per couplet. Details of each soil-gas well are given in Table 11 and their locations shown in Figure 14. 4.1.3 Sampling Frequency Soil-gas was monitored for each landfill in the following months. 4.2 Sampling Event Current Landfill Former Landfill Round 1 March 2009 March 2009 Round 2 July 2009 July 2009 Round 3 November 2009 December 2009 Round 4 December 2009 None Results of Soil-Gas Monitoring Action levels for soil-gas are specified in 6 NYCRR Part 360-2.17(f) in terms of percent LEL, which is primarily related to the amount of methane present. This discussion focuses primarily on the methane levels detected during quarterly monitoring. Hydrogen sulfide is monitored, but has no regulatory action level. 6 NYCRR Part 360-2.17(f) specifies that active measures to control decomposition gases are required when the concentration of methane or other explosive gases exceeds 25 percent of the LEL (or 1.3% methane) in facility structures, or 100 percent (%) of the LEL (or 5.3% methane) at the site boundary. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 15 4.2.1 Current Landfill A total of 23 soil-gas monitoring well clusters are positioned around the Current Landfill (Figure 13). Potential receptors, or areas where methane can accumulate in the vicinity of the Current Landfill, include the National Weather Service building located 480 ft north northwest of the Current Landfill on the north side of Brookhaven Avenue. Should methane extend to the south side of Brookhaven Avenue, active measures will be required to control its migration. The four outpost soilgas wells, GSGM-1 to GSGM-4, located along the south side of Brookhaven Avenue, are used to monitor the northern extent of the migration of landfill gas. The results of the soil-gas monitoring for 2009 are summarized in Table 12. Appendix A contains the field notes recorded during the sampling events. Instrument measurements show that methane continues to be generated in several areas of the landfill. The percent of the LEL is elevated along the western side and the southeast boundary of the Current Landfill. In addition, one point, SGM-19, along the northern side of the Current Landfill had elevated LEL readings. These levels have remained stable since 1996 when monitoring began and the current gas venting system appears to be controlling gas accumulation. These data are consistent with previous years (see Appendix C). Outpost wells, GSGM-1 to GSGM-4, located along the south side of Brookhaven Avenue showed no methane during 2009, indicating that the methane accumulation and migration does not extend to this area. Should methane extend to these outpost wells on the south side of Brookhaven Avenue, active measures will be required to control its migration. Hydrogen sulfide is a product of anaerobic decay in landfills and can produce an odor like rotten eggs. It is a nuisance, but rarely a toxicity problem. For reference, the National Institute of Occupational Safety and Health sets an exposure limit of 10 parts per million (ppm) hydrogen sulfide in the breathing zone for an 8-hour period. Hydrogen sulfide measurements collected from the soil-gas monitoring wells ranged from 0 ppm to 72 ppm. Well SGM-12A located near the south-eastern section of the landfill, had the highest hydrogen-sulfide concentration, which was above the 10 ppm exposure limit; however it was taken from a vapor point screened 2.5 - 7.5 ft below the surface and not from the ambient breathing zone. Like methane, receptors to hydrogen sulfide are considered to be in areas such as basements where T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 16 the gas can accumulate. Based upon the readings obtained from the outpost soil-gas wells along the south side of Brookhaven Avenue (GSGM-1 – GSGM-4), there is no evidence that hydrogen sulfide is migrating toward the National Weather Service building. 4.2.1.1 Trend in Soil-Gas Data Appendix C contains the results of methane monitoring for the Current Landfill from 1996 through 2008. Generally the levels of methane and hydrogen sulfide in the wells along the northwest landfill boundary and southeast corner have remained stable. 4.2.2 Former Landfill Area A total of 12 soil-gas monitoring well clusters are positioned around the Former Landfill Area. During 2009, the well clusters were monitored three times. The only existing operating facility within the immediate vicinity of the Former Landfill Area is Building 670, located approximately 650 feet to the southeast. This building houses the Chemical/Animal Holes Sr-90 groundwater treatment system. Because this facility does not have a basement, there is minimal potential for hazardous levels of landfill gases to accumulate in this structure. Based upon the three sampling events, there was no methane or hydrogen sulfide detected. Table 13 details the 2009 soil-gas monitoring results for the Former Landfill Area. Appendix A contains the field notes recorded during the sampling events. 4.2.2.1 Trends in Soil-Gas Data The results of monitoring the Former Landfill Area continue to be consistent with the initial survey of the methane- gas migration conducted in 1995, during which concentrations between 0% to 0.1% methane were recorded. Hydrogen-sulfide gas also was measured during this survey. The hydrogen sulfide results indicate there were no detectable levels during 2009. Appendix D includes the results of monitoring methane in the Former Landfill Area for 1996 through 2008. Presently, there is no measured pathway for methane-gas migration, nor do the concentrations represent an explosive hazard as shown by the nondetect readings on the LEL meter. The age of the Former Landfill Area and the types of materials disposed of would likely result in the low levels or absence of methane or hydrogen sulfide. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 17 5.0 MAINTENANCE AND REPAIR Monthly site inspections were performed by BNL at the Current and Former Landfill areas to monitor the structural and/or operational status of the landfill cap, gas vents, drainage structure, fences and environmental monitoring system (groundwater wells, soil-gas wells) in accordance with the O&M Manuals. A copy of the inspection reports is included in Appendix B. Maintenance and repair work completed or required by BNL is discussed below. 5.1 Landfill Cap and Gas Vents To prevent ruts in the landfills caused by the weight of the lawn mowers during periods of above normal precipitation, the cutting of the grass is only conducted when optimal soil conditions are evident. Small cracks in the asphalt road next to the Current Landfill were noted on the inspection logs. The cracks do not impact the structural integrity of the road. Small animal burrows were noted during the biannual LTRA inspections. Also small pine seedlings were noted growing around the edge of the landfill. Maintenance is scheduled for the Spring 2010 which will include removing the seedlings and filling all remaining animal burrows. 5.2 Drainage Structures The drainage structures at both the Current and Former Landfill areas were maintained and any obstructions removed. They were observed to be operational and structurally sound during the site inspections. From April through June 2009, vegetation was noted growing in the drainage channels of the Current Landfill and Former Landfill Area. A combination of weed whacking and herbicide was used and the vegetation was not noted in subsequent inspections. 5.3 Environmental Monitoring System The monitoring wells and soil-gas monitoring wells associated with the landfills required no significant maintenance. During 2009, the groundwater monitoring wells were repainted to minimize the affects of weather on the steel casings. Access to the soil-gas monitoring wells was cleared via mechanical weed whacking T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 18 5.4 Related Structures During routine inspections of both landfills it was noted that access to the landfill caps required walking on the unstable rip rap. Therefore, wooden staircases were installed in May 2009 at the northeast corners of both the Current and Former Landfills to allow safer access to the cap areas. The footings on the cap side of the stairs were secured to cement slabs placed on top of the cap. 6.0 CONCLUSIONS AND RECOMMENDATIONS 6.1 Groundwater Monitoring 6.1.1 Conclusions for the Current Landfill VOCs such as benzene, and/or chloroethane continue to be detected in downgradient wells 087-11, 087-23, and 088-109 at concentrations above groundwater standards. The maximum chloroethane concentration was 26.9 μg/L in well 088-109. Benzene was detected at a maximum of 2 μg/L in well 088-11. During 2009, TVOC concentrations in these three wells ranged up to 28.7 μg/L indicating that low level VOCs continue to emanate from the landfill. However, an analysis of the trends of VOCs indicated the concentrations are stable to decreasing. Landfill water chemistry parameters and metals evaluated during the year suggest that leachate continues to emanate from the landfill, but at low levels. Tritium and Sr-90 continue to be detected in the wells downgradient of the Current Landfill, but at concentrations well below groundwater standards. These concentrations were consistent with historical observations. Since 1998, there have been no detections of VOCs, water chemistry parameters or radionuclides exceeding groundwater standards in wells 087-24, 088-22, and 088-23. These wells are all screened in the mid-to deep-Upper Glacial Aquifer to monitor the vertical extent of contamination from the Current Landfill. Although low levels of contaminants continue to be detected, the landfill controls are effective as evidenced by the improving quality of groundwater downgradient of the landfill. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 19 6.1.2 Recommendations for the Current Landfill The groundwater monitoring well network is adequate at this time. No changes to the monitoring frequency are recommended. 6.1.3 Conclusions for the Former Landfill Area The Former Landfill Area is not a significant source of VOC contamination. No VOCs were detected above groundwater standards in 2009. VOC concentrations in the downgradient wells were at or near the minimum detectable limits. Landfill-leachate indicators in downgradient wells were detected at concentrations approximating those in the background monitoring wells, indicating that leachate generation is minimal to nonexistent. The Former Landfill Area no longer appears to be a source of Sr-90 contamination. Only trace amounts of Sr-90 were detected near the Former Landfill Area (Well 097-64). The Sr90 detected in wells 106-43, 106-44, 106-45 and 106-64 has been decreasing with time and is currently not above groundwater standards. The implemented landfill controls are effective, as evidenced by the improving quality of groundwater downgradient of the landfill. 6.1.4 Recommendations for the Former Landfill Area The groundwater monitoring well network is adequate at this time. No changes to the monitoring frequency are recommended. 6.2 Soil-Gas Monitoring 6.2.1 Conclusions for the Current Landfill Methane and hydrogen sulfide levels in wells located along the west landfill boundary and southeast corner have remained stable and have not shown any significant increases or decreases over time. No gas migration has been observed this year at the outpost soil-gas wells along Brookhaven Avenue. T:\LTRA\Landfills\2009 Report\Text\2009_text_v1.doc 20 6.2.2 Recommendations for the Current Landfill The soil-gas monitoring program is adequate at this time, since methane gas is still being produced and leachate is continuing to discharge from the landfill. 6.2.3 Conclusions for the Former Landfill Area Methane and hydrogen sulfide levels at the Former Landfill Area continue to show little to no landfill gas. 6.2.4 Recommendations for the Former Landfill Area The soil-gas monitoring program is adequate at this time. No changes to the monitoring frequency are recommended. 6.3 Maintenance and Repair Maintenance of the landfill caps will continue in accordance with the O&M requirements. 6.3.1 Current Landfill Monthly inspections and maintenance will continue in accordance with the O&M requirements. To prevent ruts in the landfills caused by the weight of the lawn mowers and moist surface conditions, the cutting of the grass is only conducted when optimal soil conditions are evident. Access to the soil-gas monitoring wells are cleared via mechanical weed whacking. 6.3.2 Former Landfill Area Monthly inspections and maintenance will continue in accordance with the O&M requirements. To prevent ruts in the landfills caused by the weight of the lawn mowers during periods of above normal precipitation, the cutting of the grass is only conducted when optimal soil conditions are evident. Access to the soil-gas monitoring wells are cleared via mechanical weed whacking. 7.0 REFERENCES Brookhaven National Laboratory, 1999, BNL Groundwater Monitoring Program Quality Assurance/Quality Control Project Plan, BNL, August 1999.
