A Construction and Demolition Debris landfill was then constructed on top of the old unit and closed and capped in 2004 with a similar low -permeable soil layer. Methane gas vents were installed during closure of the unlined landfill and converted to landfill gas recovery wells in 2011. In April 1995, in accordance with Rule .1633(b)(2), Wake County initiated an assessment monitoring program for the compliance monitoring wells around the landfill due to exceedances of the North Carolina 2L Groundwater Standards (NC 2L) in some of the monitoring wells. Groundwater assessments were submitted to the Solid Waste Section (SWS) in 1999 and 2000. An Assessment of Corrective Measures Report was prepared by others and submitted to the SWS, on behalf of Wake County, in July 2007 and approved in September 2007. In 2009, the County and the SWS agreed to focus on implementing the groundwater corrective action at the unlined North Wake Landfill prior to continuing the groundwater corrective action process at the Feltonsville Landfill. A letter was issued by the SWS on August 23, 2010 requesting that the County continue the groundwater corrective action process at the Feltonsville Landfill. A public meeting was held on November 17, 2010, and upon completion, the County notified the SWS that it would move forward with a Corrective Action Plan (CAP) where monitored natural attenuation (MNA) paired with institutional controls would be the primary remedy for the site. An additional assessment was requested by the SWS to determine the edge of waste through a geophysical survey and install and sample a groundwater monitoring well at the compliance boundary. As a result of volatile organic compounds (VOCs) exceeding NC 2L Standards at the compliance boundary, it was determined that MNA could not be utilized as the sole remedy. A modified CAP recommending MNA with institutional controls paired with in situ remediation by Enhanced Anaerobic Bioremediation (EAB) with the possibility of bioaugmentation was submitted to the SWS in October 2011 and approved on December 1, 2011. Injection Permit WI0500507 was issued on May 18, 2012 with the Phase One injection occurring June 18-21, 2012 and the Phase Two injection occurring March 25-27, 2013. 1.2 Aquifer Characteristics The physiography of the Feltonsville Landfill site is characterized by undulating terrain ranging in elevation from about 270 ft. to 370 ft. AMSL. The topographic highs represent filled areas on the east and western portion of the site and slope downward to the low points in the small stream drainages. These drainages surround the eastern portion of the landfill; to the north, south and west (Figure 1). The elevated area in the eastern portion of the site represents the significant landfill area. An area of slight relief, a capped cell, is located in the middle to western central Smith 1-1 Section 1 portion of the site. A small drainage network transects the site from north to south along the western boundary of the main landfill (eastern portion). Small streams also border the southern and northern boundaries of the main landfill. These streams join the north -south drainage on the western side of the main landfill and discharge to the southwest. 1.2.1 Geologic and Hydrogeologic Setting The landfill site is underlain by Triassic age fanglomerates of the Chatham Group deposited near the southeastern edge of the Durham Triassic Basin. These deposits represent alluvial fan materials deposited within the basin from surrounding upland areas in response to displacement along the Jonesboro fault which delineates the southeastern margin of the basin. The deposits consist of poorly sorted mixtures of metamorphic and igneous rock fragments within a matrix of reddish brown clayey, sandy siltstone and interbeds of mudstone or clayey sandstone (Parker, 1979). These deposits are generally weakly indurated and dip gently to the southeast. The total thickness of the conglomerate deposits is unknown but has been reported to be more than 10,000 feet near the eastern edge of the basin. Geologic mapping conducted east of the South Wake landfill facility site concluded that the Jonesboro Fault is located off -site to the east of both sites. This location compares favorably to the location of the fault as marked by Parker, 1979 (CDM, 1993b). A review of available literature and geologic maps in the area indicated the presence of several Jurassic aged diabase dikes intruded into the Triassic sedimentary rocks. A description of the diabase structure at the site is presented in the Site Geology discussion. Regional groundwater flow appears to be to the west with localized flow patterns to the streams, which border the site to the north, south, and west. These streams appear to serve as discharge points for the groundwater from the shallow aquifer. This is supported by the upward vertical gradient observed in the nested well pairs, MW-19, MW-9 and 10, and MW-13 and 15. The resource value of the aquifer underlying and adjacent to the Feltonsville Landfill is rated low, given that most of the surrounding residences utilize either the Town of Apex or the Town of Holly Springs public water distribution systems. In 1994, twelve residential structures that are within 2,000 feet of the landfill property line had domestic water wells. However, nine of these residential structures (east of the landfill) are in close proximity to a public water distribution system. These three are located west of the landfill where the closest MSWLF units have been closed for several years (CDM, 1994a). 1.2.2 Site Geology Site geology is based on previous well installation activities from previous groundwater installation and assessment activities. The soils at the site predominately consist of loose to very dense, orange and reddish brown clayey silt, with little coarse to fine sands. The overburden deposits consist of loose surficial deposit overlying partially lithified to fully lithified fanglomerates deposits. The fanglomerate deposits generally consist of poorly sorted mixtures of metamorphic and igneous rock fragments within a matrix of reddish brown clayey, sandy siltstone and interbeds of mudstone or clayey sandstone. The less dense deposits were generally encountered from the surface to about 15 ft bgs. The dense lithified fanglomerate deposits were 1-2 Smith Section 1 encountered from about 15 to 68 ft, the maximum depth explored. Moisture content, based on field evaluations, ranged from dry to moist. Competent bedrock at the site was encountered in two monitoring wells (MW-19 and MW-28d). Bedrock in monitoring well MW-28d was described as Triassic aged sedimentary rock grading downward from siltstone to conglomerate. Bedrock in MW-19 was described as diabase. Since diabase dikes have intruded the Triassic Basin in the vicinity of the Feltonsville Landfill, a magnetic geophysical survey was conducted as part of the subsurface investigation for the South Wake Subtitle D Landfill. The geophysical survey located a dike trending N45°E across both the Feltonsville and South Wake sites. The dike is steeply dipping to southwest and is 20 to 30 feet in width. The approximate location of the dike is also shown on Figure 1. The presence of the dike lead to concerns that it might potentially act as a conduit for contaminant migration in the groundwater. To address the potential impact of the dike, two clusters of nested monitoring wells were installed at the north central (MW-8, MW-9, and MW-10) and south central (MW-13, MW-14, MW-15) landfill borders where the dike apparently intersects the property boundaries. Each cluster of three wells is located perpendicular to the long axis (northwest -southeast) of the dike. During the investigation conducted at the South Wake site, an extensive evaluation of the hydrogeology of the diabase dike and associated altered zones around the dike was completed. Based on this data, the wells were screened in the more conductive zones in and around the dike. This design allows for assessing the potential horizontal and vertical components of groundwater flow around the dike. The wells are screened in the following lithologic units: MW-8 and MW-15 are screened in competent diabase that is fractured, MW-10 and MW-13 are screened intersecting the water table in weathered "baked"/altered Triassic sediments, while MW-9 and MW-14 are screened in unweathered "baked"/altered Triassic sediments. South of the MW-13, MW-14, MW-15 well cluster, across the stream, a similar but more complex cluster of four wells and three piezometers, spanning the dike horizontally and vertically, was installed on the adjacent proposed South Wake landfill as part of that site hydrogeological investigation. These monitoring wells were installed as "Well Cluster A." In 1994, groundwater samples from these monitoring wells had detected levels of barium, chromium, lead and nickel that exceed the North Carolina 2L Groundwater Standards, but were comparable to background concentrations. These inorganic metals constituents could result from naturally occurring elements that are reported to occur in relatively higher concentrations in diabase rocks. Also, chloroform was detected in MW-A6 above the NC 2L Groundwater Standard (CDM 1994b). The presence of chloroform in this well may be attributed to potable water used during core drilling. Chloroform is a degradation product of chlorine, which is used in the treatment of potable water. 1.2.3 Site Hydrogeology Groundwater elevations have been monitored during the semi-annual sampling. Groundwater elevation data collected during the most recent sampling event in April 2022 is presented in on Table 1. The depth to surficial groundwater at the site generally ranges from about 5 to 25 feet bgs. The depth to groundwater in the bedrock wells (MW-19 and MW-28) ranges from 10 to 65 feet bgs. Groundwater elevations are highest in the eastern and westernmost portions of the landfill, and lowest in the central areas. Groundwater is generally encountered in distinct fracture -induced water bearing zones, within the fanglomerate deposits. Smith 1-3 Section 1 Figure 1 presents a groundwater contour map of the shallow unconfined groundwater system, based on the April 2022 data. The groundwater high points are located in MW-2 and MW-21, located upgradient of the landfill on the eastern and western topographic highs, respectively. As shown in the figure, groundwater from the eastern portion of the site, the topographic highpoint, generally flows to the west. Localized flow components radiate off the filled area in the east and flow toward the small streams, which intersect the site and border it to the north and south. Groundwater from the closed cell to the west generally flows to the east, towards the stream that intersects the site from north to south. The streams located on the site and along its borders appear to act as discharge points for the shallow groundwater. Vertical hydraulic gradients, calculated in the local well clusters, indicate an upward hydraulic gradient. These gradients also indicate shallow groundwater is likely discharging to the streams. The horizontal hydraulic gradient at the landfill, based on April 2022 data, averages 0.019 feet/feet. Groundwater flow rates based on the hydraulic gradients, conductivity data, and soil conditions range from 0.0334 to 1.74 feet/day. The flow rate through the injection area is estimated to be approximately 0.2 feet/day. 1.3 Contaminant Distribution 1.3.1 Groundwater Quality A summary of the site groundwater quality analytical results for Appendix I and detected Appendix II volatile organic compounds (VOC) is provided on Table 4a. In general, the occurrences of detected VOCs above respective NC2L Standards have been decreasing since beginning sampling activities. Monitoring wells MW-2, -4, -6, -8, -9, -10, -11, -12, -13, -14, 45, 46, 47, and -18 have been sampled on a semi-annual basis since 1994. Monitoring wells MW-19, -20, -21, -22, -23, -24, -25, -26, -27, and -28 were installed as part of the groundwater assessment completed in December 1999 and have been sampled semi-annually since December 1999. Monitoring well MW-29 was installed as part of the additional assessment in April 2011 and has since been sampled on a semi-annual basis. Well locations are provided on Figure 1. VOCs in nearly all of the monitoring wells have been below the NC2L standards. Only samples from MW-6, -9, -10, -12, -14, -15, -17, -18, -24, -25, -26, and -27 had VOC detections above the NC2L standards during the April 2022 sampling event, with 1,4-dioxane being the only constituent that exceeded the NC 2L standard for a majority of these wells. In addition to VOC and metal analyses, samples from the site background monitoring well (MW-2) and monitoring wells MW-8, -9, -10, -12, -13, and -14 are also analyzed for MNA parameters, which include: dissolved oxygen, biological oxygen demand, chemical oxygen demand, chloride, nitrate, sulfate, sulfide, total organic carbon, carbon dioxide, ferrous iron, methane/ethane/ethane, volatile fatty acids, and dissolved hydrogen. A summary of the MNA parameter analytical results since inception of the program in November 2008 is presented on Table S. Detected concentrations of MNA parameters have varied from event to event, but occurrences of key parameters from certain wells are fairly consistent. In general, it appears that based on the 1-4 Smith Section 1 concentrations of geochemical parameters from the select wells, environments are present which favor reductive dechlorination; notably, the concentrations of nitrate, ferrous iron, sulfate, and carbon dioxide. The following evidence indicates that one or more mechanisms of natural attenuation and/or reductive dechlorination may be occurring at the site: • VOC concentrations in groundwater continue to decline. • The ratio of parent/daughter compounds continues to decrease over time. • Nitrate, ferrous iron, sulfate, and carbon dioxide continue to be detected at concentrations indicating reductive dechlorination. 1.3.2 Surface Water Quality Surface water samples for metal and VOC analysis have been collected from sample locations SW-1, SW-2, and SW-3 since 1995. Surface water sampling locations are shown on Figure 1. These locations are monitored as part of the semi-annual sampling performed at the landfill. Several estimated concentrations of VOCs have been reported in samples from each location, but generally appear to be random and infrequent. Several metals including barium, beryllium, chromium, cobalt, copper, lead, nickel, selenium, silver, vanadium and zinc have been detected at low levels in the surface water samples and are most likely attributed to naturally occurring conditions. A summary of the surface water sampling data is provided in on Table 4b. 1.4 Site Conceptual Model All available data and historical investigations at the site confirm that the unlined Feltonsville Landfill is the source of VOCS observed in groundwater. Groundwater flows in a westerly direction consistent with the site topography. The surficial aquifer discharges to the small streams to the west, north and south. Historic surface water sampling indicates that contamination is not present. Based on contaminant distribution, the diabase dike and associated structures at the site appear to provide a more conductive zone than the Triassic sediments and is acting as a preferential pathway for contamination. Groundwater elevation data from wells located within and adjacent to the dike indicate that groundwater is discharging upwards from the dike to the small streams. 1.5 Regulatory Status The unlined Feltonsville MSW Landfill was closed in 1998. The piggy -backed C&D has been closed since 2004. Smith 1-5 Section 2 Corrective Action Summary 2.1 Physical Changes in Aquifer Conditions The injection of lactate and emulsified oil into the aquifer did not produce any physical changes in aquifer conditions. 2.2 Chemical Changes in Aquifer Conditions Dissolved oxygen has shown a decreasing trend following the sodium lactate and emulsified oil injection. Groundwater conditions have generally reverted back to background conditions within 50 feet of the injection zone as shown in the MNA provided in Table 5. 2.3 Physical Changes in Plume Characteristics As contaminant degradation occurred the plume progressively reduced in size over time. 2.4 Chemical Changes in the Plume Analytical results post -sodium lactate injection for MW-8, -9, and -10 indicated that bioremediation was occurring with no VOCs detected above NC 2L Groundwater Standards in MW-8 or -10, except for 1,1-dichloroethane detected in samples collected from MW-10 in July 2012. MW-9 had detections of 1,1-dichloroethane, tetrachloroethene, trichloroethene, and vinyl chloride above NC 2L Groundwater Standards, but contaminant concentrations were decreasing. DNA analyses revealed healthy populations of bacteria (Dehalococcoides sp) in MW-9 and -10 that continued to reduce contaminant concentrations. Bacterial populations in MW-8 decreased as a result of little to no VOCs being detected during the post -injection sampling. The Phase I injection of sodium lactate successfully caused degradation of trichloroethene and tetrachloroethene to daughter products using enhanced anaerobic bioremediation in the injection area. Although the Phase I injection reduced contaminant concentrations, a second injection was needed to supply a longer lasting source of electron donors. Biodegradation can be sustained for as long as sufficient concentrations of substrate remain in the groundwater. For this reason, emulsified vegetable oil was utilized in the Phase 2 injection as it is a slow -release compound, and therefore should release organic carbon into the groundwater for three to five years, depending on site conditions. During the Phase 2 injection, a 10 percent emulsified vegetable oil solution was injected into the injection wells. Injection at each well consisted of approximately 220 gallons of water containing approximately 22 gallons of the emulsified vegetable oil product. The emulsified vegetable oil product consisted of 60 percent emulsified vegetable oil and 4 percent sodium lactate by weight, which resulted in a total injection volume of 1,100 gallons of water and 110 gallons of emulsified vegetable oil product. Smith 2-1 Section 2 Post -injection samples were collected 1, 4, 7, 10, and 12 months after injection. The April 2014 monitoring event concluded the post -injection monitoring. Analyses for each sampling event were similar to the Phase I events except that DNA analyses to determine bacterial population size and functional gene presence were only done during the April 2014 sampling event. No VOCs have been detected above the standards in MW-8 since the November 2011 semi-annual sampling event, except for the April 2019 sampling event. Samples collected from MW-8 in April 2019 had detections of 1,1-dichloroethane and tetrachloroethene above their respective NC 2L Groundwater Standards. 1,4-Dioxane was detected above its NC 2L Groundwater Standard in samples collected from MW-9 during the April 2022 sampling event. Benzene has been detected slightly above the standard since May 2015, except for the November 2015 and April 2016 sampling events, but has recently shown a decrease in concentration and has fallen below the standard in the October 2021 and April 2022 sampling events. Benzene was either reported as an estimated concentration below the standard or was not detected from September 1994 to October 2014. 1,1-Dichloroethane has historically been detected above the standard, except during the September 2019, October 2020 sampling events. 1,1-Dichloroethane concentrations have also shown a recent decline and have been detected under its NC 2L standard since the October 2021 sampling event. 1,4-Dioxane was detected above the NC 2L Standard (3 parts per billion (ppb)) at 5.6 ppb and has been detected at similar concentrations above the standard since being added to the sampling program in the fall of 2018. Total VOC concentrations have fluctuated since the March 2013 injection. In MW-10, benzene, 1,1-dichloroethane, 1,4-dioxane, and vinyl chloride were detected above their respective NC 2L Groundwater Standards. The concentration of 1,1-dichloroethane has fluctuated but shows a decreasing trend since the May 2015 sampling event. Concentrations of benzene have historically fluctuated at MW-10. As expected, the concentration of vinyl chloride has fluctuated following the Phase 2 injection and has shown a decreasing trend since the May 2015 semi-annual sampling event. No VOCs were detected above the MDLs in samples collected from MW-19 during the April 2022 sampling event. Historically, VOCs have never been detected above the standards in monitoring well MW-19. MW-29, located at the compliance boundary, has not had any chlorinated ethenes detected above the NC 2L Groundwater Standards since November 2012. 1,1-Dichloroethane and an estimated detection of 1,4-dioxane were detected in samples collected from MW-29 during the April 2022 sampling event below their respective NC 2L Groundwater Standards. Concentrations of 1,1-dichloroethane have decreased following the injection events. 1,1-Dichloroethane has been detected below the NC 2L Groundwater Standard since the January 2014 post -injection sampling event except for the October 2014 semi-annual sampling event (7.2 ppb) when it was detected slightly above the NC 2L Groundwater Standard (6 ppb). Dechlorination of chlorinated ethenes from tetrachloroethene to ethene is ongoing. Chlorinated ethene concentrations in MW-9 and -10 remain below the NC 2L Groundwater Standards. The geochemical data will continue to be evaluated to determine if conditions for reductive 2-2 Smith Section 2 dechlorination remain present. Subsequent monitoring events will be evaluated to identify any trends. 2.5 Refining the Site Conceptual Model The conceptual model will be refined as necessary based on the semi-annual sampling results. 2.6 Compliance Boundary Status The two-phase injection approach successfully reset the MNA clock and has reduced contaminants at the compliance boundary below NC 2L Groundwater Standards, with the exception of 1,1-dichloroethane and vinyl chloride, which have both shown decreases in concentration but still exceed the NC 2L Groundwater Standard in MW-10. 2.7 Off -site Migration of Contaminants of Concern There is no off -site migration of contaminants of concern based on the surface water analytical results provided in Table 4b. Smith 2-3 Section 3 Conclusion The Phase 1 injection of sodium lactate successfully caused degradation of TCE and PCE to daughter products using EAB in the injection area. The Phase 2 injection of emulsified vegetable oil supplied a long-lasting carbon source and complete reductive dichlorination is still occurring in each well. Since the Site is an unlined landfill and due to the nature of the geology in the area, it is not surprising that MW-10 continues to have contaminants above NC 2L Groundwater Standards. However, the two-phase injection approach successfully reset the MNA clock and has reduced contaminants at the compliance boundary below NC 2L Groundwater Standards, with the exception of 1,1-dichloroethane and vinyl chloride, which have both shown decreases in concentration but still exceed the NC 2L Groundwater Standard in MW-10. An additional injection will be necessary in the future once all electron donors have been consumed and complete dechlorination stalls. Semi-annual monitoring data will be used to determine when another injection is needed. Smith 3-1 Section 4 References Camp Dresser and McKee, September 2000. Feltonsville Landfill.

Any exceptions to the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or discussed below. Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC Walkley-Black, Biological Tissue: All, Non - Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7, Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320 B-2011, SM 9221 C E-2006 & SM 9222D-2006, Strontium SW-846 6010D, VOC SM 6200 B-2011, Fecal Coliform Colilert-18. VOA 8260D The laboratory control sample (LCS) for analytical batch 38470 exceeded acceptance criteria for the following analytes: Acetone (158%) and 2-Butanone (153%). These analytes were biased high and were not detected in the associated samples: XD13014-001 (MW-21), XD13014-002 (MW-4), XD13014-003 (MW-25), XD13014-004 (MW- 24), XD13014-005 (MW-23), XD13014-006 (MW-22), XD13014-007 (MW-27), XD13014-008 (MW-26), XD13014-009 (TRIP BLANK), XD13014-010 (MW-18), XD13014-011 (MW-8), XD13014-013 (MW-9), XD13014-015 (MW-10), XD13014-017 (MW-19), and XD13014-019 (MW-29). Also, due to the large number of spiked analytes, there is a high probability that one or more analytes will recover outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally outside criteria. The following analytes recovered marginally outside LCS criteria: 2-Hexanone (133%). Due to the large number of spiked analytes, there is a high probability that one or more analytes will recover outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally outside criteria. The following analytes recovered marginally outside LCS criteria in batch 38612: 2-Butanone (137%). Associated samples: XD13014-021 (MW-6), XD13014-022 (MW-28), XD13014-023 (MW-20), XD13014-026 (MW-17), XD13014-027 (MW-16), XD13014-028 (MW-15), XD13014-029 (DUP), XD13014-030 (TRIP BLANK), XD13014-031 (MW-13), XD13014-033 (MW-14), XD13014-035 (MW-12), and XD13014-037 (EQ BLANK). Reanalysis of the following samples were performed outside of the analytical holding time for Dichlorodifluoromethane due to exceeding acceptance criteria in the continuing calibration verification (CCV) during initial analysis: XD13014-002 (MW-4) and XD13014-011 (MW-8). Both sets of data have been reported. The LCS for batch 38715 and Run 2 for samples XD13014-002 (MW-4) and XD13014-011 (MW-8) had acetone recovered outside the upper control limit for acetone. The recovery for trans- 1,4-Dichloro-2-butene did not recover in the LCS for batch 38715 associated with Run 2 of XD13014-002 (MW-4) and XD13014-011 (MW-8). Trans-1,4-dichloro-2-butene for LCS in batch 38470 recovered within the control range for trans- 1,4-Dichloro-2-butene. The continuing calibration verification (CCV) associated with samples XD13014-021 (MW-6) and XD13014-027 (MW- 16), for Acetone recovered above the upper control limit. The sample(s) associated with this CCV were non -detect for the affected analytes; therefore, the data has been reported.

This analyte was biased high and was not detected in the associated samples: XD13014-021 (MW-6) and XD13014-027 (MW-16). All analytical runs for these two samples have been reported since Run 2 and Run 3 were analyzed outside holding time. Metals 6020B Sample XD13014-001 (MW-21) was cloudy in appearance; therefore in order to protect the integrity of the instrument it was diluted 2 fold. The LOQ has been elevated to reflect the dilution. The method blank associated with batch 38146 had Beryllium detected at a concentration that was above the DL but below the LOQ. All samples associated with this method blank were non -detect for Beryllium. The MS/MSD for batch 38141 and parent sample XD13014-017 (MW-19), recovered outside the upper control limit for Sodium. The associated LCS passed acceptance criteria. Mercury 7470A The MS for batch 38111 and parent sample XD13014-010 (MW-18), recovered marginally outside the lower control limit. The associated LCS and MSD passed acceptance criteria. The MS/MSD for batch 38559 and parent sample XD13014-021 (MW-6), recovered marginally outside the lower control limit. The associated LCS passed acceptance criteria. Nitrate 300.0 The following samples were analyzed 3-4 hours outside of analytical holding due to instrument issue and also amount of samples to analyze in a short time frame: XD13014-011 (MW-8), XD13014-013 (MW-9), XD13014-015 (MW-10), XD13014-017 (MW-19), and XD13014-019 (MW-29). Reanalysis of the following samples was performed outside of the analytical holding time due to a dilution for matrix of non -target compounds: XD13014-013 (MW-9), XD13014-015 (MW-10), XD13014-033 (MW-14) and XD13014-035 (MW-12) The original analysis for sample XD13014-031 (MW-13) contained matrix that interfered within the retention time of nitrate. Reanalysis was performed outside of holding time, but the LCS was analyzed in a bracket with an opening CCV that exceeded the low limit. However, the LCS passed criteria. The reanalysis was analyzed alongside a spiked aliquot to confirm the retention time of nitrate in the presence of matrix interference. The reanalysis confirms the original analysis. Both runs have been reported. The MS/MSD for batch 38968 and parent sample XD13014-031 (MW-13), recovered marginally outside the lower control limit. The associated LCS passed acceptance criteria. BOD For sample, XD13014-015 (MW-10): The 300ml bottle had a low starting DO for setup. The minimum starting DO is 7.0 mg/L and the 300ml bottle had a measurement of 6.36 mg/L. The method blank result was higher (@0.25 mg/L) than the method -required limit of 0.20mg/L. A qualifier ("4") has been added to the BOD results for associated samples XD13014-031 (MW-13), XD13014-033 (MW-14), and XD13014-035 (MW-12). TDS Sample XD13014-017 (MW-19) yielded high residual mass for TDS analysis. The sample yielded 0.2642 grams of residue. The SOP states the working range is 0.0025-0.200g. The balance is verified up to 150g each analytical day. If you have any questions regarding this report, please contact the Pace Project Manager listed on the cover page.
