(Duncklee & Dunham) has prepared this April 2010 Groundwater Monitoring and Injection Evaluation Report for the above - referenced site. This report presents a summary of current injection activities and the results from the sampling event conducted in April 2010. Certification of the report in accordance with the requirements of the Administrative Agreement (AA) between Kayser -Roth, the North Carolina Department of Environment and Natural Resources, and Duncklee & Dunham is attached. Groundwater levels have recovered from the 2007 drought conditions and resaturated the area previously subjected to potassium permanganate injection. The average rise in water levels from 2007 to 2010 was just over nine feet. The purple colored water associated with the active permanganate ion was detected in shallow aquifer wells in the source area, indicating continued distribution of the oxidant and contact with the dissolved contaminants. As requested by Kayser -Roth and required by the AA, Duncklee & Dunham is continuing with the preparation of the Remedial Investigation Plan and conceptual remediation plan to fill data gaps from assessment and corrective action documents previously submitted to and approved by the DENR Division of Water Quality, Groundwater Protection Section.

The plant currently manufactures socks and the property contains one main plant building and several smaller outbuildings located to the south and southeast of the main plant (see Figure 2). Burlington Industries, Inc. (Burlington) constructed the main plant building on undeveloped land in 1952 and operated the facility until 1982 when it was acquired by Kayser -Roth. In the spring of 1999, environmental site assessment activities detected several chlorinated volatile organic compounds (VOCs) in groundwater at' concentrations exceeding the North Carolina 2L groundwater standards. The primary groundwater constituent detected is tetrachloroethene (PCE). According to plant personnel, PCE was used for weed control along the southern fence line. This usage was discontinued in the late 1970s. A Comprehensive Site Assessment Report (CSA) dated December 17, 1999, and several subsequent addendum reports were subsequently completed by GaiaTech, Inc. (GaiaTech) of Atlanta, Georgia. GaiaTech installed 11 on -site and eight off -site (i.e., off property to the south) saprolite unit wells, and four on -site Type III bedrock unit (DW) monitoring wells to determine the horizontal and vertical extent of dissolved VOC impact in groundwater (see Figure 2). Soil assessment activities conducted by GaiaTech did not indicate the presence of significant residual PCE in the source area unsaturated zone. Low levels of residual PCE contamination were detected in only one soil boring (the boring for monitoring well MW-1 Ob) near the, south fence line. 1.2 Corrective Action Plan and Injection Permitting In late 2001, Duncklee & Dunham, P.C. (Duncklee & Dunham) continued site assessment activities and prepared a Corrective Action Plan (CAP) to address groundwater remediation. The CAP, submitted to the North Carolina Department of Environment and Natural Resources (DENR) in February 2002, outlined a plan to address the dissolved PCE plume through in -situ chemical oxidation (ISCO) via injection of potassium permanganate. Following the installation of an additional monitoring well as requested by DENR, a CAP Addendum was submitted to the DENR — Division of Water Quality (DWQ) on November 25, 2002. Site assessment activities to support the CAP included further assessment in the reported source area (i.e., the southern fence line area). Soil samples were collected from several borings advanced along the southern fence line near well MW-10b and revealed low levels of PCE in one soil sample. This result supported the previous finding that residual soil PCE contamination along the southern fence line appeared to be minor and isolated. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, 2010 Page 2 of 9 An injection pilot test was proposed in the CAP to determine the most practical and cost-effective method' of oxidant delivery and to estimate overall groundwater treatment time. Duncklee- & Dunham submitted an Application for Permit to Construct and/or Use a Class 51 Injection Well to the DWQ, Aquifer Protection Section (APS) - Underground Injection Control (UIC) Program in late October 2002. An injection permit was issued to Kayser -Roth by DWQ on January 7, 2003. Duncklee & Dunham requested an amendment to the injection permit in correspondence dated September 27, 2004. DWQ amended the permit in early 2005 to allow the injection of permanganate slurry in the suspected source area. The injection permit was renewed and approved without modification on August 1, 2007, by the UIC Program. 1.3 Summary of Previous Injection Activities Phase I injection pilot test activities, performed on July 14-16, 2003, and Phase II injection pilot test activities, performed between September 16-19 and 22-25, 2003, were used to ascertain an effective delivery method and evaluate the performance of the oxidant. Effectiveness monitoring tasks performed during Phase I and Phase II showed the 1 to 2.5% potassium permanganate solution injected significantly reduced VOC levels in both the shallow and deep aquifer zones. However, after a period of approximately six months subsequent to the Phase II injection, VOC concentrations in saprolite wells near the source area rebounded to pre -injection levels. Contamination rebound in the shallow aquifer zone was attributed to dissolution of residual contaminants remaining in the source area. The 1 to 2.5% potassium permanganate solution, while highly effective in the dissolved VOC area of the groundwater plume, was not able to overcome the residual VOC levels in the source area. Phase III injection was conducted on March 15-17, 2005 and involved injection of a 3040 35 percent potassium permanganate slurry into the source area in the vicinity of MW-10b (see Figure 3). Prior to Phase III injection event, Duncklee & Dunham requested the UIC Program amend the injection permit for the use of potassium permanganate slurry. In February 2007, Duncklee & Dunham requested that the injection permit be renewed to facilitate water injection in to the aquifer. The purpose of the injection was to improve distribution and contact of residual potassium permanganate with the aquifer by moving the slurry farther away from•the injection zone. The UIC Program approved the injection permit renewal as documented in a letter dated August 1, 2007. On September 24-28, 2007, water was injected into boreholes within the source area near the Phase III injection wells. The Phase IV water injection was performed at nine soil boring points (Pt-1 to Pt-3 and Pt-5 to Pt-10, see Figure 2). Each point was advanced with a direct push rig using two inch rods. Borings were advanced to approximately 30 feet below land surface (ft bls), with the exception of Pt-3 and Pt-8 which were advanced to refusal at 22 ft bls and 28 ft b1s, respectively. During the Phase IV injection event, City of Asheboro municipal water was injected into the potassium permanganate slurry in the shallow saprolite portion of the aquifer through the mjection' points at pressures ranging from approximately 150 to 200 pounds per square inch (psi) at a. rate of four to ten DUNCKLEE & DUNHAM, P.C. J April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, 2010 Page 3 of 9 gallons per minute (gpm). Approximately 5,969 gallons of water was injected in to the shallow saprolite aquifer unit. Following the water injection, groundwater monitoring was performed on October 8 and 9, 2007. This was the sixth monitoring event performed following the Phase III injection event. PCE remained the primary groundwater constituent present in saprolite and bedrock aquifer unit wells (see Table 1). 2 Injection and Groundwater Monitoring Activities 2.1 Injection Activities No new injection activities have occurred since the September 2007 injection of clean water into the nine soil boring points (Pt-1 to Pt-3 and Pt-5 to Pt-10). The groundwater table was at a low in September 2007 due to drought conditions which extended into 2008. Since the drought, the groundwater has risen about 9.15 feet as measured in April 2010 and compared to October 2007 water levels (see Table 2). This water level rise has effectively acted like a water injection event as the rising water flushed the permanganate ions from the slurry remaining in the capillary fringe zone and out through the plume. The presence of purple colored water noted in several monitoring wells during the April 2010 sampling event (described - below) indicates the permanganate ion is active and the oxidant remains in the source area. 2.2 Groundwater Sampling Methods Physical and geochemical parameters were collected from saprolite monitoring wells MW-1, MW-3, MW-6b, MW-7, MW-8, MW-10b, MW-11, MW-13, MW-17, MW-20, MW-21, MW-22, and bedrock wells DW-1 through DW-5. Prior to sample collection, water levels were collected in all wells, with the exception of MW-2b and MW-14 (see Table 3), which was inaccessible for this event (April 13-14, 2010). Monitoring wells MW-15, MW-16, and MW-18 were dry during this sampling event. On May 20, 2010, access was obtained to MW-2b for water level measurement and sampling. Groundwater samples were collected using EPA -approved low -flow sampling techniques in the selected saprolite and bedrock monitoring wells located immediately adjacent to and within the core groundwater plume. A low -flow electric submersible pump equipped with new, disposable polyethylene tubing was used to purge the well and withdraw each sample. The groundwater samples were collected in laboratory -provided bottles immediately after purging. - The sample bottles were labeled and logged on to a chain -of -custody form, and transported to Pace Analytical Services (Pace) in Huntersville, North Carolina in an ice filled cooler (MW-2b sample was . submitted to Environmental Science Corporation in Lebanon, TN). Groundwater samples were analyzed for PCE, TCE, cis- and trans-1,2 dichloroethene, and vinyl chloride using EPA Method 8260B (MW-2b was analyzed for the full 8260B scan). Saprolite and bedrock monitoring wells located within and immediately adjacent to the core of the groundwater plume were also sampled for manganese and chromium according to Method 200.7 MET ICP, and chloride according to Method 4500. Copies of the laboratory analytical report and chain -of -custody forms are included in Appendix A. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, 2010 Page 4 of 9 During the groundwater sampling process, field geochemical parameters were collected from select monitoring wells. The field parameters included pH, electrical conductivity, oxygen reduction potential (ORP), dissolved oxygen (DO), and temperature. Additionally, a field colorimeter instrument was used during mg the recent samplmg event to evaluate potassium permanganate concentrations in select wells. This field data is summarized in Table 4 and the field sampling forms are included in Appendix B. 3 . Sampling Results 3.1 Groundwater Flow Results Water levels measured (see Table 3) on April 13, 2010, were used to create a groundwater contour map for the saprolite (Figure 3) and bedrock units (Figure 4). During this monitoring event, groundwater flow in the saprolite aquifer was found to be to the south-southeast at an average horizontal hydraulic gradient calculated to be approximately 0.032 ft/ft. Based on the data collected from this sampling event, the flow direction and gradient is consistent with historical data results. Similar to previous results, this event revealed the presence of a divergent groundwater flow direction to the south-southwest and east across the site. This flow pattern, observed in the shallow aquifer (see -- Figure 3), is believed to be influenced by remnant bedrock fracture patterns in the saprolite and partially weathered rock. This divergent flow pattern is also evidenced by the shape of the dissolved PCE plume in the saprolite aquifer unit. Groundwater flow in the bedrock aquifer unit (see Figure 4) is primarily to the east-southeast in response to an average horizontal hydraulic gradient of approximately 0.038 ft/ft. The flow direction and hydraulic gradient data is consistent with previous data. 3.2 Groundwater Sampling Results PCE remains the primary groundwater constituent present in saprolite and bedrock aquifer unit wells (see Table 1). Recent PCE results found in the saprolite and bedrock aquifer unit wells collected during the April and May 2010 sampling event have been contoured and shown in cross section and plan view on Figures 5, 6, and 7. Inorganic metals and field geochemical data results are also included in Tables 1 and 4, respectively. Plots of selected analytical parameters are also shown in Appendix C. 3.2.1 Saprolite Wells Results 3.2.1.1 VOCs During this event, VOCs were detected at various concentrations in MW-2b, MW-3, MW-6b, MW-13, MW-17, and MW-21. A summary of historical (i.e., pre -injection, Phase I and II pilot test, slurry injection, and post water injection phases) and recent data results are shown in Table 1. Field parameter data from this event are summarized on Table 4. Trend graphs for select wells are included in Appendix C. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph, County, North Carolina August 24, 2010 Page 5 of 9 Based on this data, the following observations are made: • The highest concentration of PCE occurred in MW-17 at 5,740 micrograms per liter (µg/L). The remaining saprolite wells showed detectable PCE concentrations above the 2L groundwater standards at levels ranging from 4.3 µg/L in MW-6b to 637 µg/L in MW-3. • The PCE historically detected in MW-8 since September 1999 was not detected for the first time during the April 2010 sampling event. Field observations and data indicate the permanganate solution has extended to MW-8. MW-8 showed over a ten fold increase in dissolved manganese thought to be caused by the migration of oxidation degradation products to the well and the rise in groundwater levels since the end of the 2007 to 2008 drought. . • MW-2b had last been sampled from 1999 through 2001 and had PCE at 3, 9.1, 6, and 7.8 µg/L and chloroform at 41, 24, 24, and 23 µg/L. On May 20, 2010, PCE was detected at 14 µg/L while chloroform was not.detected. • No TCE was detected in the saprolite wells. No other target VOCs were detected above the laboratory detection or 2L groundwater standards. • . Monitoring wells MW-1, MW-7, MW-8, MW-10b, MW-11, MW-20, and MW-22 showed PCE below laboratory detection limits. • Based on pre -injection and post injection PCE data trends, PCE appears to be decreasing in the saprolite wells following the injection work phases with the exception of MW-17 (see Appendix C and Table 1). 3.2.1.2 Inorganic Data Chloride, manganese, and chromium are typical byproducts of the oxidation process, and so are used to evaluate PCE degradation and as a tracer to evaluate the distribution and impact of the oxidant to the aquifer. These results are summarized in Table 1 and the following observations can be made at this time: • Manganese levels were elevated in saprolite wells closest to the injection zone. Data collected in wells MW-8 (13.7 milligrams per liter (mg/L)), MW-10b (187 mg/L), and MW-6b (9.59 mg/L) showed manganese at concentrations higher than peripheral wells MW-17 (1.37 mg/L and MW- 13 (1.56 mg/L) and downgradient wells MW-21 (3.45 mg/L) and MW-3 (1.63 mg/L). All the manganese levels were higher than the 50 µg/L 2L standard. • Based on pre -injection and post injection manganese data trends, manganese appears to have increased somewhat after each injection event in the saprolite wells. Higher concentrations of manganese have also been noted (see Appendix C) after the the drought period ended and groundwater levels rose (see Tables 1 and 2). • No chloride concentrations could be detected in source area wells MW-8 and MW-1 Ob because of the high permanganate concentration. Chloride levels from the remaining saprolite wells ranged from 3.49 mg/L in MW-11 to 152 in MW-6b. None of the chloride concentrations exceeded the 250 mg/L 2L standard. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, 2010 Page 6 of 9 • Chromium levels showed a similar pattern to manganese levels. Data collected from saprolite J wells closest to the injection zone showed chromium slightly higher than wells located on the _ periphery or hydraulically downgradient. No chromium concentrations could be detected in source area wells MW-8 and MW-IOb because of the high permanganate concentration. MW-17 contained chromium at 0.0109 mg/L and- MW-6b contained chromium at 0.0064 mg/L. Peripheral well MW-13, in addition to downgradient wells MW-21 and MW-3, showed chromium levels below laboratory detection limits. The chromium level in MW-17 was slightly higher than the 10 µg/L 2L standard. • Based on pre -injection and post injection data, no consistant data trends were observed for chlorides and chromium. 3.2.1.3 Field Parameters Field parameters collected during the April 2010 sampling event are presented in Table 4. The field parameters include pH, electrical conductivity, oxygen reduction potential (ORP), dissolved oxygen (DO), and temperature. Additionally, a colorimeter was used to measure the concentration of potassium permanganate in impacted wells. Based on the data collected, the following observations can be made. • Based on the colorimeter data, detectable levels of permanganate were present in monitoring wells MW-6b, MW-8, MW-10b, MW-13, and MW-17. MW-8 and MW-10b exhibited by far the highest concentrations with colorimeter readings of 116.8 mg/L and 143.7 mg/L, respectively. • DO levels in the wells sampled remained stable when compared to previous data. Elevated DO levels continue in well MW-8 (9.98 mg/L). The remaining saprolite wells showed DO levels ranging from 7.64 mg/L in MW-2b to 2.3 mg/L in MW-21. • Generally, the pH data collected ranged from 4.49 to 5.87. Wells nearest to the source area, MW- 8 and MW-6b, showed pH values of 5.43 and 5.84, respectively. The remaining outlying saprolite wells contained pH values ranging from 4.49 in MW-2b to 5.87 in MW-17. • ORP data indicate aerobic conditions in the saprolite wells. Among the saprolite unit wells, MW- 1 Ob showed the highest ORP reading at 834 mV (millivolts) while elevated ORP results were also noted in MW-8 (604 mV) and MW-17 (684 mV). Data collected in the remaining saprolite wells showed ORP ranging from 304 mV (MW-21) to 364 mV (MW-2b). • During this monitoring event, conductivity data fluctuated across the site. The highest measurements of conductivity were measured in the outlying wells MW-8 (1,130 micro -Siemens per centimeter (µS/cm)), MW-6b (900 µS/cm), and MW-21 (830 µS/cm). The remaining saprolite wells showed conductivity ranging from 195 µS/cm (MW-2b) to 200 µS/cm (MW-17). This data shows no discernible trends. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, 2010 Page 7 of 9 3.2.2 Bedrock Wells Results 3.2.2.1 VOCs During the April 2010 sampling event, PCE was the primary groundwater constituent detected in the bedrock wells DW-1, DW-2, DW-3, DW-4, and DW-5. A summary of historical (i.e., pre -injection, Phase I and II pilot test, slurry injection, and post water injection phases) and recent data results are shown in Table 1. Field parameter data from this event are summarized on Table 4. Based on this most recent sampling event for the bedrock wells, the following observations are made: • Analytical results show PCE continues to be present above 2L groundwater standards. 'DW-2 continues to show the greatest impact of PCE at a concentration of 717 µg/L. In the remaining bedrock wells, PCE ranged from 576 µg/L (DW-1) to 1.2 µg/L (DW-4). • Based on pre -injection and post injection PCE data trends, PCE appears to be increasing in the bedrock wells following the injection work phases (see Appendix Q. The post water injection data results also show TCE present in the bedrock wells at low to trace levels. TCE ranged from 34.9 µg/L (DW-4) to 10.8 µg/L (DW-5). No other target VOCs were detected above the laboratory detection limits in the bedrock wells. • TCE is often considered a daughter product of chlorinated compound degradation. Although trace amounts of these compounds have been seen in bedrock wells over the course of the sampling program, the post injection data trend reveal a slight increase when compared to pre - injection data results for TCE. No other VOC daughter products are present at this time. • Bedrock wells DW-1 and DW-2 show a correlation between the byproducts of the oxidation process and PCE concentrations. As manganese and chlorides increase in concentrations, PCE decreases and vice versa. Manganese concentrations remained relatively low until after the end of the drought period when groundwater levels rose (see Tables 1 and 2 and Appendix C). 3.2.2.2 Inorganic Data As stated earlier, chloride, manganese, and chromium are typical byproducts of the oxidation process to evaluate PCE degradation and are used as a tracer to evaluate the distribution and impact of the oxidant to the aquifer. These results for the bedrock wells are summarized in Table 1 and the following observations can be made at this time: • Manganese levels are significantly elevated in DW-1 (6.75 mg/L), DW-2 (11.2 mg/L), DW-3 (6.71 mg/L), DW-4 (19.1 mg/L), and DW-5 (9.57 mg/L) above concentrations results obtained during the pre -water injection monitoring event in April 2007 and the post -water injection event in October 2007. This appears to be a result of the higher water levels in April 2010 compared to 2007. All the manganese levels were higher than the 50 µg/L 2L standard. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August'24, 2010 Page 8 of 9 li, • Among the bedrock wells, chloride concentrations are higher in downgradient wells compared to wells closer to the source area. DW-1 and DW-4 contain chlorides at concentrations 44.6 mg/L and 40.2 mg/L. The downgradient wells DW-2, DW-3, and DW-5 contain chlorides at concentrations ,126 mg/L, 70.8 mg/L and 51.9 mg/L, respectively. None of the chloride concentrations exceeded the 250 mg/L 2L standard. • Analytical data collected in the bedrock wells showed chromium levels decreased slightly in comparison to the October 2007 sampling event in wells DW-1 (0.0073 mg/L) and DW-2 (<0.005 mg/L). Chromium levels increased in wells DW-3 (0.0099 mg/L), DW-4 (0.0712 mg/L), and DW-5 (0.0211 mg/L). Chromium exceeded the 10 µg/L 2L standard in DW-4 and DW-5. 3.2.2.3 Field Parameters Field parameters collected in the bedrock wells during the October 2007 sampling event are presented in Table 4. The field parameters include pH, electrical conductivity, ORP, DO, and temperature. Additionally, a colorimeter was used to evaluate during the recent sampling period to ascertain the relative concentration of potassium permanganate in impacted wells. Based on the data collected, the following observations can be made. Based on the colorimeter data, detectable levels of potassium permanganate were present in all five bedrock wells. Upgradient well DW-4 (1.0 mg/L) showed the highest --concentration of permanganate while downgradient well DW-2 (0.10 mg/L) showed the lowest concentration of permanganate. • Data collected in the bedrock wells continue to show aerobic conditions. DO levels ranged from 9.21 mg/L in DW-4 to 0.89 mg/L in DW-5. This data shows no discernible trends. • ORP levels ranged from 340 mV (DW-2) to 150 mV (DW-3) while conductivity values ranged from 9990 µS/cm (DW-2 and DW-3) to 565 µS/cm (DW-4). Based on previous ORP and conductivity readings, no discernable trends can be seen at this time. 4 Conclusions and Recommendations Based on the recent groundwater -monitoring results and injection data the following conclusions and recommendations are derived. Groundwater table elevations have risen significantly since the previous sampling events of the drought of 2007. Concurrent with the rise of water levels, indicator parameters "such `as colorimeter readings and manganese levels indicate the impact of the""ermangaate _oxidant slurry has spread to the south of the source area. Manganese levels were elevated in 'saptolite wells closest to the injection zone and lower in the peripheral and downgradient wells. The rise in water levesl from 2007 to 2010 appears to have flushed permanganate from the slurry injection area as indicated by the increased manganese levels since 2007. DUNCKLEE & DUNHAM, P.C. April 2010 Monitoring and Injection Evaluation Report Asheboro Sock Facility, 515 West Balfour Avenue Asheboro, Randolph County, North Carolina August 24, ' 2010 Page '9 of 9 • MW-8, located south and downgradient of the treated source area showed over a ten fold increase in dissolved manganese, a by-product of contaminant oxidation. For the first time, MW-8 also contained a high level of permanganate oxidant as evidenced by colorimeter measurements. • Monitoring wells MW-2b, MW-3, MW-6b, MW-13, MW-17, and NM-21 continued to show PCE impacts at various concentrations. The highest concentration of PCE occurred in MW-17 at 5,740 µg/L. - • The non -detect result for PCE in saprolite wells MW-8 and MW-10b and the high manganese concentrations indicate that the permanganate slurry is still an active source of oxidant when the groundwater level reaches the slurry. • DW-1 and DW-4, used to evaluate the injection process in and adjacent to the source area, . indicate PCE levels are slow to degrade. Residual impacts of the injection process are present in the deep wells as evidenced by increased magnesium concentrations. • Groundwater in the shallow portion of the aquifer was found to flow towards the south-southeast and southwest and in the bedrock portion of the aquifer was found to flow towards the south- southeast. Both sets of groundwater flow data were consistent with previous data collected. • An additional sampling event is recommended in 2010-2011 to gather long-term data on the effects of the water injection in distributing the permanganate and the affects the permanganate slurry has on PCE concentrations and to determine if the permanganate has reached several areas in the suspected plume that will be investigated under the REC Remedial Investigation Work Plan.

The quality control ` f samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a 11J411 qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a 11J5° or a 11J611. The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J311 qualifier.
