Results of Site Assessment Activities Former Newco Fibre Properties Charlotte, North Carolina H&H Job No. MFP-005 1.0 INTRODUCTION This report presents the results of soil and ground water assessment activities conducted by Hart & Hickman, PC (H&H) at the former Newco Fibre properties located at 430 East 36th Street and 409 East 35th Street in Charlotte, Mecklenburg County, North Carolina in connection with the application of RM 36th Street Investors (“Prospective Developer”) into North Carolina’s Brownfields Program. The scope of services described herein was performed in general accordance with H&H’s Assessment Work Plan dated January 8, 2007, approved by NCDENR under cover of a February 13, 2007 e-mail from Ms. Carolyn Minnich. Deviations from the Work Plan are noted in this report. The objectives of the assessment activities were to evaluate potential impacts from historical site operations and to determine if any identified impacts may pose a risk to: • future site users via direct contact with soil; • construction workers via direct contact with soil and potentially groundwater; and • future site users via vapor intrusion from volatile contaminants in shallow soil and/or ground water to indoor air. The results were also evaluated to determine if additional assessment is warranted at the site or if remedial activities are warranted to make the site suitable for redevelopment pursuant to a Brownfields Agreement. S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 2 2.0 SITE BACKGROUND The site consists of two parcels of commercial/industrial land with a combined area of approximately 8.49 acres. The location of the site is shown on Figure 1, and the site layout is shown on Figure 2. A brief historical summary is presented below, and key information is shown on Figure 2. The northern tract, located at 430 East 36th Street, was most recently operated by Newco Fibre Company as a textile fiber recycling facility. Based on a review of available historic information, fiber processing operations have been conducted on this property since 1930. Prior to 1930, General Fire Extinguisher operated a machine and pipe shop on the property. According to Mr. Rayner Weir, a representative for Newco Fibre, no chemicals were used in the processing of fiber at the site. Fiber recycling activities included sorting, cleaning with beaters to remove dirt, and baling. The only chemicals used on the property were hydraulic oil in the presses and heating oil for the furnace. Hydraulic oil was most likely stored in or outside of the maintenance room indicated on Figure 2. Heating oil was stored in an underground storage tank (UST) located near the southeastern corner of this tract. The UST was reportedly removed in the late 1970s or early 1980s by a licensed contractor; however, no documentation regarding the UST removal is available. The southern tract is located at 409 East 35th Street and consists of a vacant warehouse built in 1992. Previous warehouse facilities were built in the late 1950s and were operated by Hangwell Hangers (western portion) and Norfolk Southern Railroad (eastern portion). Prior to warehousing, the site was occupied by Sinclair Refining Company since at least 1929. Sinclair stored and distributed gasoline and processed oils for sale to the textile industry. Information regarding previous site operations is not available; however, Sanborn maps depict Sinclair’s gasoline and oil storage and processing areas (see Figure 2). S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 3 3.0 ASSESSMENT ACTIVITIES 3.1 Assessment Plan Based upon H&H’s review of historical operations, the sampling design for this project was biased to target potential areas of impacted soil and ground water based on the historical information available for the site and surrounding properties. The Assessment Work Plan identified 13 locations for soil sampling and proposed collection of ground water samples at 9 of these locations. H&H prepared the Assessment Work Plan in coordination with NC DENR’s Brownfields Program in connection with its evaluation of the property. The proposed locations are depicted on Figure 3 and summarized below: 430 East 36th Street (northern tract) • Immediately downgradient of the maintenance shop (1 boring/temporary well) • In the vicinity of the former coal bin and rail spur (1 boring) and former boiler house (1 boring/temporary well); • On the downgradient side of the former UST (1 boring/temporary well); • Inside the main, larger building (3 borings/temporary monitoring wells); • At the topographic low near the northwest corner of the property (1 boring/temporary well). 409 East 35th Street (southern tract) • In the vicinity of the former gasoline tanks (1 boring/temporary well); • In the former textile oil processing area (1 boring/temporary well); • In the immediate vicinity of former oil storage areas (3 borings). As discussed below, soil samples were collected at all 13 locations; however, the ground water sampling plan was modified due to sampler refusal above the water table at many of the sampling locations. S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 4 3.2 Soil Sampling Soil sampling activities were conducted on March 14 and 15, 2007. Using a track-mounted Geoprobe equipped with direct push technology (DPT), Probe Technologies, Inc. (Probe) of Statesville, North Carolina advanced 13 soil borings (SB-1 through SB-13) at the locations shown on Figure 4. Each boring was advanced until refusal with completion depths ranging from 7 to 18 feet below grade. Ground water was encountered in SB-9 and SB-10 at the time of drilling. Boring logs are presented in Appendix A. Soils encountered in each boring were screened for the presence of volatile organic compounds (VOCs) utilizing a photoionization detector (PID) and were evaluated for visual/olfactory indications of petroleum impacts. The value displayed by the PID represents the total vapor concentration of VOCs. However, the PID is not capable of determining the species or absolute concentrations of the VOCs. Therefore, it is only a screening tool that aids in detecting the presence of VOCs in soil. Additional field screening was conducted to determine the locations of SB-11, SB-12, and SB-13 inside the larger warehouse building at 430 East 36th Street. Review of historical operations did not indicate any specific areas of concern. Therefore, for SB-11, SB-12, and SB-13, multiple, off-set borings were advanced at each location to a depth of approximately 2 feet below grade. The soils were field-screened with the PID, and the location with the highest PID readings was selected as the boring location. At each boring location (SB-1 through SB-13), two soil samples were collected for possible laboratory analysis. One soil sample was collected from a shallow screening interval (between 0 and 5 feet), and one soil sample was collected from a deep screening interval (between 5 feet and the total depth of the boring). In general, soils that displayed the highest PID readings were sampled. Soil samples were collected in laboratory provided containers and placed immediately in a chilled cooler with ice for transport to Environmental Science Corporation (ESC) of Mt. Juliet, S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 5 Tennessee, a North Carolina certified laboratory. The shallow soil samples were analyzed for VOCs by EPA Method 5035/8260B, semi-VOCs (SVOCs) by EPA Method 8270C, and the eight Resource Conservation and Recovery Act (RCRA) metals (arsenic, barium, cadmium, chromium, lead, selenium, and silver by EPA Method 6010B and mercury by EPA Method 7471). The deeper soil samples were held at the laboratory pending the results of the shallow samples. The deep samples were only analyzed if shallow samples were impacted or if there was obvious field evidence of impacts. A total of 18 soil samples were analyzed. 3.3 Ground Water Sampling As mentioned above, ground water was encountered in soil borings SB-9 and SB-10. A decontaminated stainless steel groundwater sampling point was installed in each of these borings to allow collection of ground water samples. The ground water samples were collected on March 15, 2007. However, due to DPT refusal, ground water was not observed in other borings intended as both soil and ground water sampling points. Therefore, H&H returned to the site on May 18, 2007 with an air rotary drilling rig capable of installing temporary monitoring wells. Because there was no field or laboratory evidence of soil impacts (see Section 4.1) and due to access constraints with the larger drilling rig, the ground water sampling plan was modified and only three temporary monitoring wells (TW-1, TW-2, and TW-3) were installed. Boring logs and temporary monitoring well construction information are presented in Appendix A. Discrete ground water sampling points and temporary monitoring well locations are shown on Figure 4. The two discrete ground water sampling points and three temporary monitoring wells were purged until pH, conductivity, and temperature were observed to be generally stable. Once the field parameters stabilized, groundwater samples were collected in laboratory provided bottles, placed in a cooler with ice, and forwarded under chain-of-custody procedures to ESC of Mt. Juliet, Tennessee. The ground water samples were analyzed for VOCs by EPA Method 8260B, SVOCs by EPA Method 8270, and RCRA 8 metals by EPA Methods 6010B/7470A. S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 6 4.0 ASSESSMENT RESULTS Soil and ground water sampling results are summarized in Tables 1 and 2, respectively. Analytical laboratory reports are provided in Appendix B. The following sections discuss the results of the field investigation. 4.1 Soil Results Field screening of the soil did not indicate any obvious impacts. No soil staining was observed, and PID readings were generally low. The highest PID readings were detected in soil borings SB-1, SB-2, and SB-3 with maximum readings of 13.9 ppm. 28.4 ppm, and 16.6 ppm. Field screening of the other borings did not indicate any PID readings greater than 5 ppm. In general, the soil sample with the highest PID reading in each boring was sent for laboratory analysis. PID readings are provided on the boring logs in Appendix B. In order to assess the potential risk associated with compounds detected at the site, soil analytical results were compared to EPA Region IX Preliminary Remediation Goals (PRGs) 2004 and DENR Inactive Hazardous Sites Soil Remediation Goals (SRGs) 2006 for unrestricted site uses. It is important to note that PRGs and SRGs are conservative screening levels and are not intended to be cleanup levels. Concentrations of chemical constituents below the screening levels should not pose a concern, whereas concentrations of chemical constituents above the screening levels indicate that further evaluation may be warranted. VOCs Only three VOC constituents, acetone, MEK, and naphthalene, were detected at concentrations above laboratory reporting limits. None of the detected concentrations exceed the soil screening levels. Therefore, soil collected from the site does not appear to be impacted with VOCs. S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 7 SVOCs Several SVOC constituents were detected in soil samples collected at the site. Soil samples collected from borings SB-2 and SB-13 were reported with concentrations of select polynuclear aromatic hydrocarbons (PAHs) that slightly exceeded their respective screening levels (Table 1). In the shallow soil sample collected from SB-2, only benzo(a)pyrene was detected at concentrations above screening levels. The detected concentration (0.43 mg/kg) slightly exceeds the SRG, residential PRG, and industrial PRG for this constituent. The deeper sample collected at this location did not contain any detectable SVOCs. At SB-13, benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, and indeno(1,2,3-cd)pyrene were detected in shallow and/or deep soil samples at concentrations slightly above screening levels. Based on the minor concentrations reported and the lack of PAHs in surrounding soil borings, it is not likely that a source of PAHs is present at the site. Metals In addition to the regulatory screening levels, Hart & Hickman compared the metals results to a list compiled by NC DENR (August 2006) of background metals concentrations in North Carolina soils. These background values are reported on Table 1. Three metal compounds, arsenic, cadmium, and chromium, were detected at concentrations above regulatory screening levels. Each of these compounds is discussed below. Arsenic was detected in soil samples collected from SB-9 (3 mg/kg) and SB-10 (1.1 mg/kg) at concentrations above residential (0.39 mg/kg) and/or industrial (1.6 mg/kg) PRGs. However, the detected concentrations are within the range of published background concentrations (1.6 to 180 mg/kg). Cadmium was detected in shallow samples collected from SB-11 and SB-13 at concentrations of 8.5 mg/kg and 7.7 mg/kg. These concentrations slightly exceed the SRG of 7.4 mg/kg, but are below both the residential and industrial PRGs for this constituent. The detected concentrations are also slightly above the range of published background concentrations for cadmium in NC soils (0.54 to 5.8 mg/kg). S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 8 Most of the soil samples collected at the site contained concentrations of total chromium above the regulatory screening levels for hexavalent chromium; however, the detections were substantially below the regulatory screening levels for trivalent chromium. To further assess these results, H&H requested analysis of hexavalent and trivalent chromium for the soil sample with the highest reported total chromium concentration. The deeper soil sample collected from boring SB-11 contained 500 mg/kg total chromium, 390 mg/kg trivalent chromium, and 2.4 mg/kg hexavalent chromium. These results suggest that the chromium detections at the site are most likely representative of trivalent chromium concentrations. In addition, most of the chromium detections are within the range of published background soil concentrations for this constituent (2 to 150 mg/kg). 4.2 Ground Water Results Ground water results were compared to North Carolina 15A NCAC 2L Standards. These published values are generally based on minimizing risk associated with direct ingestion of ground water and, therefore, are conservative. As shown in Table 2, only one VOC compound (xylene) and four metals (barium, chromium, lead, and selenium) were detected in ground water at concentrations above laboratory detection limits. Only lead was detected at a concentration above 2L standards in the ground water sample collected from SB-10. The detected concentration of 35 µg/L at this location exceeds the 2L standard of 15 µg/L. It is important to note that the ground water samples were not filtered in the field; thus, the metals concentrations in these samples may include a contribution from colloidal particles suspended in the sample in addition to that dissolved in the samples. S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 9 5.0 SUMMARY AND CONCLUSIONS Soil and ground water assessment activities were conducted by a Brownfields Prospective Developer, RM 36th Street Investors, at the former Newco Fibre properties located at 430 East 36th Street and 409 East 35th Street in Charlotte, Mecklenburg County, North Carolina. Soil samples were collected from thirteen locations, and ground water samples were collected from five locations. The purpose of the assessment activities was to assess potential impacts from historical on-site or off-site activities focusing on the areas with the highest probability of impact. The assessment was performed in accordance with H&H’s Assessment Work Plan, dated January 8, 2007, and approved by NC DENR on February 13, 2007. The assessment results identified concentrations of PAHs in soil slightly above conservative screening levels at two locations. Metals concentrations in soil were detected at several sampling locations, but appear to be within the range of published background concentrations for NC soils. One ground water sample contained a detection of lead at a concentration above the 2L standard. It is important to note that the ground water samples were not filtered; therefore, the metals results may be due to suspended sediment and may not be indicative of the actual dissolved metals concentrations in the ground water. No other compounds were detected in the ground water samples at concentrations above 2L standards. In sum, the assessment documented herein revealed modest environmental concerns which, if managed pursuant to an appropriate Brownfields agreement, should not present a material risk to human health or the environment when the property is redeveloped. The conclusions presented in this report are professional opinions, based solely upon visual observations of the site and vicinity and our interpretation of the available historical information and analytical results as described in this report. It should be recognized that this study was not intended to be a definitive investigation of contamination at the subject property. It is possible S:\AAA-Master Projects\Merrifield Partners - MFP\MFP-005 Newco Fibre\Assessment Report.doc H art & Hickman, PC 10 that currently unrecognized contamination may exist at the site. Opinions and recommendations presented herein apply to site conditions existing at the time of our investigation.

J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low O (ESC) Sample diluted due to matrix interferences that impaired the ability to make an accurate analytical determination. The detection limit is elevated in order to reflect the necessary dilution. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useableunless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate 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 concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" 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 "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier. Page 45 of 45 12065 Lebanon Rd. Mt.

J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low O (ESC) Sample diluted due to matrix interferences that impaired the ability to make an accurate analytical determination. The detection limit is elevated in order to reflect the necessary dilution. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useableunless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate 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 concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" 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 "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier. Page 60 of 60 12065 Lebanon Rd. Mt.

Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries,surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate 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 concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" 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 "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier. Page 24 of 24 12065 Lebanon Rd. Mt.

J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). DefinitionsAccuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate 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 concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" 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 "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier. Page 16 of 16 12065 Lebanon Rd. Mt.

J2 Surrogate recovery limits have been exceeded; values are outside lower control limits J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate 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 concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" 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 "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier. Page 31 of 31
