Executive Summary Fort Liberty Site FTBR-308 (Site) is at the location of the Blue Ramp on Pope Army Airfield (Figure 1). In 1956, the Blue Ramp hydrant system consisted of two pump houses and six underground fuel hydrant lines for aircraft refueling. In 1966, this was expanded to a hydrant system consisting of three pump houses, each including six underground storage tanks (USTs), and nine hydrant lines. Each pump house conveyed jet fuel to the Blue Ramp hydrant system from the six 50,000-gallon USTs, located immediately adjacent to the pump houses. In total, there were 18 non-regulated USTs which had a storage capacity of 900,000 gallons. This accounted for a total of 900,000 gallons of jet fuel stored within 18 non- regulated USTs. The volume of the hydrant pipeline system was approximately 110,500 gallons. According to historical documents, the Blue Ramp fueling system was discontinued in the 1990s. During the spring 2023 gauging and groundwater sampling event, the maximum thickness of free product was 2.12-feet at monitoring well PT-2. Free product was found under the airfield and in areas extending towards the unnamed tributary to Little River. The current extent is comparable to the historical extent. The sampling results from the spring 2023 event show that the highest concentrations were detected in MW7-20 with the following above applicable NC2L: benzene at 1,300 micrograms per liter (µg/L), toluene (1,400 µg/L), Xylenes (1,500 µg/L), 2-Methylnaphthalene (43 µg/L), naphthalene (110 µg/L), C5-C8 aliphatics (5,500 µg/L), C9-C18 aliphatics (4,840 µg/L), and C9-C22 aromatics (1,470 µg/L). No gross contaminant levels (GCLs) were exceeded. Previously, multiple remedial technologies have been utilized and will be discussed in greater detail later in this report. The most recent technology employed was Advanced Fluid Vapor Recovery (AFVR). This was utilized until 2019 when, due to a lack of recovery, a change was made to hydrophobic socks. The socks have been employed at the site skimming product that enters the monitoring or recovery well where they are deployed. The receptors in the area include those in the office buildings over the dissolved plume and the unnamed tributary which historically has had product entering the stream. Due to the extensive vegetative growth in this area, it is no longer possible to safely observe this tributary. Past responses to free product in this area involved a cut-off trench and later multiple biosparge wells in an attempt to keep fuel out of the tributary. Free-product has not been observed in the wells adjacent to the stream until this most recent sampling event. This was discussed at the Tier I in August 2023 to determine a path forward at the Site and is discussed in detail in the conclusions and recommendations section. iv C. TABLE OF CONTENTS A.

SITE HISTORY AND CHARACTERIZATION 1.0 Introduction This Corrective Action Plan (CAP) monitoring report presents the results of the April-May 2023 groundwater monitoring event conducted by United States Army Corps of Engineers (USACE), Savannah District at compliance cleanup site SS07 (FTBR-308, Blue Ramp Hydrant System) on Pope Army Airfield (PAAF). FTBR-308 is hereafter referred to as Site 308 in this report. AFVR was selected as the preferred remedial technology in the System Enhancement Report (URS, 2009) which amended the cleanup strategy in the Corrective Action Plan (CAP) for this site (Black & Veatch, 2005). In 2019, AFVR events were changed to absorbent socks as either a sheen or no product was observed in the vacuum truck after previous AFVR events. Currently, the absorbent socks are replaced on a semi- annual schedule when conducting groundwater sampling and gauging at the site. 2.0 Site History and Characterization The U.S. Army Reservation at Fort Liberty was established in 1918 as a major logistic, training, and mobilization deployment center for the XVIII Airborne Corps, which is part of the U.S. Army’s mobile infantry, assault, and armored forces. Fort Liberty occupies approximately 161,024 acres in southeast North Carolina. Approximately 143,140 acres are designated for field maneuvers and military exercises. The cantonment area, which is in the eastern part of Fort Liberty, occupies 11,354 acres and includes approximately 6,195 buildings. Most military maintenance and production facilities, supply facilities, operation and training facilities, community installations, and family and troop housing are located within the cantonment area. The Blue Ramp hydrant system was originally constructed in 1956 and consisted of two pump houses and six USTs for aircraft refueling. This system was expanded in 1966 to three pump houses, 12 new USTs (6 for each pump house), and nine hydrant lines. Each pump house was connected to six 50,000-gallon USTs and conveyed fuel to the Blue Ramp via the hydrant system. The total storage of the 18 unregulated USTs was 900,000 gallons (Figure 1 and 2). A further 110,500 gallons was in the hydrant pipeline system. The Blue Ramp hydrant system was decommissioned in the 1990’s. Table 1 and 2 provide information for the UST and the hydrant system. Little information is known or available about the USTs that were in place at the Site. A major spill occurred in the 1960s, in an area currently known as the Claw Ramp. Several thousand gallons of JP-4 was released during a fuel transfer. The JP-4 reportedly traversed through the storm sewer system and was contained at drainage gates. An unknown amount of JP-4 was recovered, while a further unknown amount infiltrated the ground. In the mid-1980s, Pope Air Force Base personnel found JP-4 discharging into an unnamed tributary to the Little River. The unnamed tributary is adjacent to Building 740. 2 Figure 4 depicts a potential receptor map which shows the proximity of the site, unnamed tributary, and Little River. The historic JP-4 product plume observed at the site indicates the source of the release could include one or more of the USTs, associated piping, the hydrant system, or hydrant vaults located in the area of the Claw and Blue Ramps. All infrastructure is located upgradient of the JP-4 plume as shown in the cross-section provided in the CAP (Black & Veatch, 2005) and is provided as Figure 2 and 7. 2.1 Land Use After removal of the USTs, land use at the Site remained as an airfield. Typical of an airfield, there are hangars and an office in the area of the Site. The site has little topographic relief in the area where the USTs were located as they were under the airfield. The main topographic feature is immediately downgradient of the site where an unnamed tributary is located and has formed a steep ravine. No land use changes are expected for this area. 2.2 Property Owners and Occupants The owner of Site 308 and all surrounding property is the U.S. Army which is provided in Table 3. The Site Map is provided in Figure 2 and 3 which includes the former UST locations, buildings in the area and utilities. 2.3 Receptor Information There are 25 water supply wells on Fort Liberty. Eight of these wells are located near the cantonment area and are used for golf course irrigation. The remaining wells are outside the cantonment area and are used for purposes other than potable water supply. There are no known water supply wells within 1,500 feet of Site (Figure 4). In 2010, the Fayetteville Public Works Commission (PWC) and Harnett County Department of Public Utilities (DPU) began providing all of Fort Liberty’s water. Harnett County DPU obtains their water from the Cape Fear River. The Fayetteville PWC also obtains their water from the Cape Fear River, as well as Glenville Lake, and Big Cross Creek (all sources are part of the Cape Fear River basin). Prior to 2010, water was obtained from the Little River via an intake downstream of Site 308. This water intake and Little River are beyond the 1,500-foot perimeter around the site. No surface water features are within 500-feet of the center of the site. The unnamed tributary is approximately 750 feet from the Site. The unnamed stream flows to the northwest to an area of wetland before entering the Little River. Little River is classified by NCDEQ as Water Supply III (WS-III) stream due to the presence of water intakes along the stream. No wellhead protection areas are within 1,500-feet of Site 308 and no water wells are known to exist within 1,500-feet of the site. Vapor intrusion for local buildings is not a concern as the depth to free product and groundwater is outside the screening zone for petroleum compounds (>15 feet) (ITRC, 3 2014). Depth to water in the area of the building is approximately 21-feet below ground surface (bgs), therefore the building is outside the screening zone for petroleum compounds. 2.4 Deep Aquifers in the Coastal Plain Physiographic Region The Fort Liberty area is underlain by three freshwater aquifers: the Middendorf Aquifer (also known locally as the Black Creek Aquifer), the Cape Fear Aquifer, and the saprolite-basement aquifer. The major water-bearing strata at Fort Liberty are within the Middendorf Formation and are referred to as the Middendorf Aquifer. The Middendorf Aquifer consists of coarse to fine-grained silty or clayey sands with interbedded light gray or tan clays. When combined with the surficial aquifer, the Middendorf Aquifer is locally known as the Black Creek Aquifer. Unconfined conditions are typical near the top of the saturated zone of the Middendorf Aquifer, but semi-confined and confined conditions can occur at greater depths. In upland areas of Fort Liberty, the potentiometric surface of the Middendorf Aquifer is as deep as 80 feet bgs. Near perennial streams in the eastern part of the reservation, the potentiometric surface is near the ground surface. The interbedded and discontinuous clay layers in this aquifer support localized, unconfined, perched water zones within 20 feet of the ground surface and are referred to as the surficial aquifer. Many of the perched water zones dry out seasonally and are not a reliable water supply source. Sandy surface soils at Fort Liberty are highly permeable and allow precipitation to rapidly infiltrate and enter the groundwater system. The surficial groundwater system is recharged almost entirely by percolation of area precipitation through these sands. The Cape Fear Aquifer is within the Cape Fear Formation, which is composed primarily of clay interbedded with silt and silty sand under confined conditions. In the vicinity of Fort Liberty, the uppermost 5 to 10 feet of the Cape Fear Formation form a confining unit that restricts vertical movement of water between the overlying Black Creek Aquifer sediments and the silt sand units of the Cape Fear Formation. The Cape Fear Aquifer, therefore, receives little or no recharge from the overlying Black Creek Aquifer. None of the wells in the cantonment area are screened in the Cape Fear Aquifer; however, some of the more distal wells at Fort Liberty may be screened in this aquifer. The Cape Fear Aquifer is used for potable and industrial water supplies by the community of Spring Lake. The saprolite-basement aquifer underlies the Cape Fear Formation at depths ranging from 140 to 300 feet bgs. This aquifer is generally assumed to yield little water, and no supply wells in the area are known to tap solely into this aquifer. 4 2.5 Site Geology and Hydrogeology The soils at Site 308 generally consist of alternating sequences of silt, silty to clayey sand, and discontinuous clay lenses. Sand grain sizes range from very fine to very coarse with isolate gravel. Geologic cross-section maps are presented on Figure 8. Figure 8 represents an approximate north-south geologic section. Soils consists of silt to silty sand from the ground surface to a depth ranging from 12 to 20 feet bgs with interspersed thin clay lenses. The silty unit overlies a laterally continuous and homogenous sandy unit ranging in thickness from 10 feet in the eastern portion of the site to 30 feet in the western portion of the site. A discontinuous clay unit underlies the sandy unit on the east transitioning to sand and silty sand in the west. During past investigative activities, five exploratory soil borings were advanced to bedrock at PAAF. The Middendorf Formation and Cape Fear Formations were identified. The Middendorf Formation was encountered at depths ranging from 25-30 feet bgs and the Cape Fear Formation was encountered at depths ranging from 58- 80 feet bgs. A saprolitic zone of gray green to red silts and silty clay was observed beneath the Cape Fear Formation. Quartz veins were observed in the saprolite at some boring locations. At four boring locations, micaceous chlorite schist (bedrock) was observed. Isolated areas of fill are present in the western portions of the site consisting of clay, clayey sand, and asphalt. It was estimated that the fill thickness is approximately 20 feet in the vicinity of Building 740. While installing MW7-20, asphalt was encountered at a depth of 10-feet bgs. During the current monitoring event, depth to groundwater at the site ranged from approximately 11 to 21 feet bgs. A potentiometric surface map based on May 2023 data is included as Figure 5. Groundwater was flowing to the south-southeast during the most recent sampling event. Based on rising-head permeability tests performed at 15 monitoring wells at the site, the hydraulic conductivity of the surficial aquifer ranged from 0.5 to 82.3 feet/day with an average of 29 feet/day. A step-drawdown test was also completed at MW7-15 which yielded a transmissivity of 0.32 feet2/minute. To determine the hydraulic conductivity from the step drawdown test, an assumed aquifer thickness of 22-feet was used and yielded a hydraulic conductivity of 26 feet/day. The groundwater velocity calculated at the site is 1.16 feet/day or 423 feet/year. 2.6 Previous Remedial Efforts In the mid-1980’s, fuel was found discharging into an unnamed tributary. To attempt to prevent further discharges of fuel to the stream, a cut-off trench and sump was installed adjacent to the stream. The system was reconfigured in 1992 to rebuild and extend the north-south leg beyond storm drain utilizing a seal around the 30-inch diameter pipe. The existing 24-inch sump was removed and replaced with a 48-inch 5 sump. This trench operated until 2000 when it was concluded it was no longer operationally effective as a barrier to the stream due to the geotextile installed during trench construction becoming fouled. In 1996, a bioslurping pilot test was conducted near the cut-off trench. This system was moved to be adjacent to Building 736 in 1997 to better assess the feasibility of the system. Full operation was not achieved until 1999 due to electrical and pump issues. Once operational, the system was plagued with operational issues but was able to remove 67,500 gallons of water and 3,500 gallons of free product; removal through the vapor phase was not quantified. Biovent wells were installed in 1999 adjacent to Building 736 where the bioslurping wells were also installed. The biovents appeared to reduce the vadose zone hydrocarbon concentrations but the effectiveness was limited due to free product floating on the water table. An AFVR pilot test was completed in December 1999. During the test, 1,880 gallons of total fluids were recovered including 628 gallons of measurable light non-aqueous phase liquid (LNAPL). The CAP was approved in 2005 by the North Carolina Department of Environmental Quality (NCDEQ). In the fall of 2006, a multi-phase total fluids recovery and treatment system to remove contaminated soil vapors, contaminated groundwater, and LNAPL was installed at the site. The multi-phase recovery system consisted of 14 six-inch diameter recovery wells located throughout the LNAPL plume and a soil vapor extraction (SVE) blower system. In September of 2009, URS submitted a System Enhancement Report (SER) recommending that the system be amended to improve LNAPL recovery efficiency (URS, 2009). The methodology for LNAPL and vapor recovery was modified from the multi-phase total fluids recovery system to performing periodic and frequent AFVR events at the site and then treating the recovered fluids through the existing groundwater treatment system. Following the recommendations of the SER, the recovery system was partially dismantled to allow for the conversion of the multi-phase recovery wells to AFVR recovery wells, and an additional 15 two-inch diameter recovery wells were installed. Conversion of the multi-phase wells was performed by removing the total fluids recovery pumps from the wells and removing the SVE blower system. Additionally, a 1,500-gallon phase separation tank was installed adjacent to the location of the former SVE system, and a curtain of four biosparging wells was installed to limit potential LNAPL and contaminated groundwater discharge to the unnamed creek located immediately downgradient of the site. Total fluids recovered by AFVR were historically treated and disposed through an onsite groundwater treatment system consisting of an oil/water separator (OWS), a recovered LNAPL storage tank, effluent transfer pump, filter housing(s) equipped with oleophilic filter socks, and a two-tray low profile air stripper. The final treated effluent was discharged by gravity line to the unnamed tributary of the Little River 6 under a General National Pollutant Discharge Elimination System (NPDES) permit. The groundwater treatment system has not been operational since November 2012, and fluids generated from AFVR events have been transported offsite for disposal since that time. The groundwater treatment system has been dismantled and removed from the site. Monitoring well MW7-22, which is located downgradient of the site, was sampled on February 25, 2014, to determine if there were any GCL exceedances and to confirm that the groundwater contaminant plume was stable. Three analytes exceeded the North Carolina 2L (NC2L) Groundwater Quality Standard (GWQS) at MW7-22: benzene (80.9 µg/L), naphthalene (25.4 µg/L), and final C9-C22 aromatics (370 µg/L). GCLs were not exceeded. Groundwater results were discussed at the October 15, 2014 Tier 1 meeting. The team determined that groundwater monitoring frequency would be every five years in advance of the 5-year review. A total of 29 wells were also abandoned in November 2014 in advance of upcoming construction. During the well abandonment in November 2014, three wells were discovered on the airfield that were not shown on historical maps; these wells were surveyed prior to a comprehensive gauging event. These wells were arbitrarily assigned the following well IDs: RW-A, RW-B, and RW-C. Following the January 26, 2016, Tier 1 meeting, the compressor that powers the biosparge wells was inspected and found not to be running. Parsons contracted with Lewis Systems and Service Company to troubleshoot the compressor. On February 11, 2016, Lewis Systems inspected the compressor and determined that it needed to be replaced. Lewis Systems replaced the Becker compressor on March 2, 2016, with an identical model. In 2018, the compressor failed again and during a Tier I meeting in November it was determined not to replace the compressor until after data from the February 2019 sampling was reviewed. Based upon that review, the system was not placed back into operation. AFVR at the time was being completed by utilizing a vacuum truck to remove fluids and vapors from extraction wells. AFVR was discontinued in 2019 due to the lack of recovered product. In 2019, absorbent hydrophobic socks were instead deployed to skim off free product that accumulates in the monitoring and recovery wells. These socks are replaced on a semi-annual basis when gauging and sampling of the groundwater occurs. Current sampling results are similar to those observed in 2014 with exceedances of the NC2L but below the GCL. 3.0 Field Activities and Sampling Methodology A long-term monitoring event for groundwater was conducted by USACE, Savannah District in April-May 2023. Groundwater samples were collected from ten monitoring wells at Site 308 and analyzed for volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), extractable petroleum hydrocarbons (EPH), and volatile petroleum hydrocarbons (VPH) using low-flow sampling methods. 7 3.1 Water Level and Free Product Gauging Depth to groundwater was measured on April 28 – May 1, 2023, at site monitoring wells prior to the sampling activities. Static groundwater level measurements were collected using an electronic oil-water interface probe. The indicator probe was lowered into each monitoring well until the alarm sounded and/or the indicator light illuminated. The probe was then withdrawn several feet and slowly lowered again until the oil and/or groundwater surface was contacted, as noted by the alarm and/or indicator light. Water level measurements were measured to the nearest 0.01-feet from the top of the well casing. Depth to product, depth to water measurements, and groundwater elevations from accessible monitoring wells are summarized in Table 4 and 7. A potentiometric surface map depicting groundwater flow is provided in Figure 5. Groundwater flow at the site is generally toward the northwest. Free product was encountered at the following wells: MW7-16 (0.17-feet) PT-2 (2.12-feet) RW-03 (0.01-feet) RW-04 (0.04-feet) RW-05 (0.01-feet) RW-12 (0.01-feet) MW-308A (1.62-feet) MW-308E (0.01-feet) MW-308F (2.10-feet) Depth to water ranged from approximately 12-feet bgs to 23-feet bgs and free product ranged in thickness from a sheen to approximately 2-feet. MW-308A is not on the map but is assumed to be in the area north of Hurst Drive where other similarly named wells are located. 3.2 Low-flow Sample Collection Groundwater samples were collected using a low-flow purge method with a bladder pump. Immediately before purging a well, the static water level below the top of the well casing and the total depth of the well were measured to the nearest 0.01-feet and recorded in the field logbook or on sampling forms. The volume of water in the well was calculated based on the static water level and the well construction information. Well volume calculations were recorded in the field logbook or on sampling forms. 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 was within the well screen. 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 were lower than 10 Nephelometric Turbidity Units (NTUs) or within 10%, temperature values within a range of 0.5 8 degrees Celsius, pH readings within 0.1 Standard Units (SU), conductivity values within 3%, and DO values within 5%. The rate of pumping was noted in the field logbook or on sampling forms with the purge rate adjusted, as necessary, to avoid purging any monitoring well to dryness. Attempts were made to equilibrate the recharge rate of the aquifer and purge rate. All sampling equipment was protected 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 immediately in an ice-filled cooler for preservation. The sampling information was logged on the laboratory provided chains-of-custody. 4.0 GROUNDWATER ANALYTICAL RESULTS SUMMARY This section presents the results of groundwater analysis from the April/May 2023 event at the Site. A summary of the groundwater analytical data is presented in Table 8 and on Figure 7. Laboratory data sheets are included in Appendix B with field notes and forms included in Appendix A. 4.1 Historical Analytical Data Historical data for the Site is summarized in Table 9. All concentrations at the site have been and remain below the GCL but above applicable NC2L values. The detections at MW7-20 were higher than those detected in the past at the site. This is a well where free product was historically found and is likely why the concentration is higher in that well. 4.2 2023 Groundwater Results During the 2023 sampling event, no detections were above the GCL for any analyte. The following analytes were detected above the NC2L: 2-methylnaphthalene, Acrolein, Benzene, Naphthalene, Toluene, Xylenes, bis(2-ethylhexyl) phthalate, C5- C8 aliphatics, C9-C18 aliphatics, and C9-C22 aromatics. The relative percent difference (RPD) was calculated and presented in Table 10. Calculated RPDs for most analytes were below 20% indicating the data is usable for decision making. VOCs that had RPD >20% include naphthalene. Naphthalene is flagged in the data and is not expected to be related to sampling procedural issues. RPD for all SVOC data was <20%. Massachusetts Department of Environmental Protection (MADEP) EPH RPD was >20% for C11-C22 Aromatics (135%) and C9-C18 Aliphatics (140%). For the duplicate sample, the first lab run of MADEP EPH data was flagged due to calibration issues and was run again outside of hold time. This high RPD does not indicate an issue with the sampling or field procedures. 9 4.3 Free Product Recovery During gauging of the free product at the Site, hydrophobic socks and any free product recovered from the wells was placed in a sealable bucket for transport to the Directorate of Public Works (DPW). Materials were properly disposed of at the DPW. Approximately 1.5 gallons of product were removed from the monitoring and recovery wells at the Site. 5.0 CONCLUSIONS AND RECOMMENDATIONS During the spring 2023 gauging and sampling event, a more comprehensive gauging was able to be completed due to construction activities being completed at the airfield. This gauging found free product in several wells on the airfield as well as product being observed in wells that were clear for a number of events near the unnamed tributary. Free product was observed to vary in thickness from a sheen to approximately 2 feet. MW-308A is not on the map but was found to have 1.62-feet of product in the well. This is currently a 1-inch well and it is recommended to be replaced with a 4-inch well to better facilitate product recovery. The construction of the well is unknown but a new well will be installed as to be screened across the water table to allow LNAPL to enter the well. Based on the free product periodically observed in the monitoring wells, especially those nearest the unnamed tributary to Little River, it is recommended that an updated investigation be completed to determine the current extent of the plume and determine which zones are saturated with product. Consultation with NCDEQ will determine if an updated CAP is needed or if the current CAP can be utilized and a New Technology Cleanup Plan be submitted prior to any additional remedial actions at the site. Many of the remedial options in the 2005 CAP have been utilized at the Site either at pilot scale or full scale. Thermal treatment was determined to be applicable but was ruled out due to cost in the CAP. A pilot study may provide information to determine if this is a technology that may be useful to target areas of residual product at the Site which have not been able to be addressed through the other remedial technologies. Restarting AFVR was considered but these events rapidly show diminishing rates of return. It is recommended to continue with the absorbent socks currently and to discuss the gauging schedule at the next Tier I. Groundwater sampling did not find any concentrations above the GCLs but several contaminants were above the NC2L. During the sampling, several of the large vaults had locking mechanisms that were inoperable and two of the lids were found to be heavier than what the field crew could safely lift to gain access. Sampling will be completed again in October 2023 at select monitoring wells where product is not present, and the vault is accessible. Additional supplies will be available to attempt access into vaults that were inaccessible either due to the mass or broken latches/locking mechanisms. 10 No change is recommended to the sampling and gauging schedule until after data is received from the October 2023 sampling and gauging event. 6.0 REFERENCES Black and Veatch, 2005.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperatures of the 4 coolers at receipt time were 1.8°C, 1.9°C, 2.9°C and 5.2°C GC/MS VOA Method 8260D_DOD5: Surrogate recovery was outside acceptance limits for the following matrix spike duplicate (MSD) sample: TW7-03-04-23 (680-234331-5[MSD]). The parent sample's surrogate recovery was within limits. The MSD sample has been qualified and reported. <EXPLANATION_REQUIRED> Method 8260D_DOD5: The surrogate recovery for the blank associated with analytical batch 680-776880 was outside the lower control limits. The samples were reanalyzed and both sets of data have been reported. Method 8260D_DOD5: The method blank for analytical batch 680-777079 contained Carbon disulfide above the method detection limit (MDL). Associated samples were not re-analyzed because results were less than the reporting limit (RL) OR practical quantitation limit (PQL). Method 8260D_DOD5: The laboratory control sample duplicate (LCSD) for analytical batch 680-777079 recovered outside control limits for the following analytes: 1,4-Dioxane. These analytes were biased high in the LCSD and were not detected in the associated samples; therefore, the data have been reported. Method 8260D_DOD5: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for analytical batch 680-777079 recovered outside control limits for the following analyte(s): Iodomethane. Iodomethane has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. Method 8260D_DOD5: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for analytical batch 680-776880 recovered outside control limits for the following analytes: Chloroethane, Hexachlorobutadiene, Naphthalene, 1,2,3-Trichlorobenzene and 1,2,4-Trichlorobenzene. Method 8260D_DOD5: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 680-777079 were outside control limits for one or more analytes. See QC Sample Results for detail. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits. Method 8260D_DOD5: The following sample was diluted to bring the concentration of target analytes within the calibration range: TW7-03-04-23 (680-234331-5). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC/MS Semi VOA Method 8270E_DOD5: Surrogate recovery for the following samples were outside control limits: MW7-16-04-23 (680-234331-1), 308-DUP-1-04-23 (680-234331-2), MW1-04-23 (680-234331-4), TW7-03-04-23 (680-234331-5) and MW7-22-04-23 (680-234331-6). Re-extraction and/or re-analysis was performed and surrogate recovery was outside control limits. Method 8270E_DOD5: The surrogates recoveries for the blank associated with preparation batch 680-779620 and analytical batch 680-780179 were outside control limits. The associated sample(s) was re-prepared and/or re-analyzed outside holding time. Both sets of data have been reported. Duplicate sample bottle for 3520/8270E_DOD5 was broken in the lab area. Sample was scheduled for RX, however insufficient volume remains to RX.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperatures of the 3 coolers at receipt time were 0.7°C, 1.9°C and 3.2°C Receipt Exceptions The following samples were received at the laboratory outside the required temperature criteria: RW-18-05-23 (680-234374-1), RW-16-05-23 (680-234374-2), RW-17-05-23 (680-234374-3), RW-08-05-23 (680-234374-4) and MW7-18-05-23 (680-234374-5). This does not meet regulatory requirements. The client was contacted regarding this issue, and the laboratory was instructed to proceed with analysis. GC/MS VOA Method 8260D_DOD5: Surrogate recovery for the following samples were outside control limits: RW-18-05-23 (680-234374-1), RW-16-05-23 (680-234374-2), RW-17-05-23 (680-234374-3) and MW7-18-05-23 (680-234374-5). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed. Method 8260D_DOD5: Surrogate recovery for the following sample was outside control limits: RW-08-05-23 (680-234374-4). Evidence of matrix interferences is not obvious. A reanalysis was attempted for 680-234580-41 but resulted in a mechanical failure on the instrument so only the original run was reported. Method 8260D_DOD5: Surrogate recovery for the following samples were outside control limits: RW-17-05-23 (680-234374-3) and MW7-18-05-23 (680-234374-5). Evidence of matrix interference due to high target analytes is present; therefore, re-extraction and/or re-analysis was not performed. Method 8260D_DOD5: Surrogate recovery for the following sample was outside control limits: RW-08-05-23 (680-234374-4). Evidence of matrix interferences is not obvious. Method 8260D_DOD5: The surrogate recovery for the blank associated with analytical batch 680-778627 was outside the upper control limits. Method 8260D_DOD5: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for analytical batch 680-778568 recovered outside control limits for the following analyte(s): Chloroethane. Chloroethane has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified. Method 8260D_DOD5: The following samples were diluted to bring the concentration of target analytes within the calibration range: RW-17-05-23 (680-234374-3) and MW7-18-05-23 (680-234374-5). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC/MS Semi VOA Method 8270E_DOD5: Surrogate recovery for the following sample was outside control limits: RW-08-05-23 (680-234374-4). Re-extraction and/or re-analysis was performed and surrogate recovery was outside control limits. Method 8270E_DOD5: The method blank for preparation batch 680-777555 and analytical batch 680-777551 contained Bis(2-ethylhexyl) phthalate above the method detection limit (MDL). Associated samples were not re-analyzed because results were less than the reporting limit (RL) OR practical quantitation limit (PQL). Method 8270E_DOD5: The laboratory control sample (LCS) for preparation batch 680-777555 and analytical batch 680-777551 recovered outside control limits for the following analytes: 4,6-Dinitro-2-methylphenol and 2,4-Dinitrophenol. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data has been reported. Method 8270E_DOD5: A portion of the following samples listed was used for analysis, rather than testing the entire sample amount in the original container, due to the sample container was not the appropriate size: RW-08-05-23 (680-234374-4). As such, the required solvent rinse of the original container could not be performed.
