It is currently used by the Salt Lake City Police Department as a training facility and the Fire Department for equipment storage. Figure 1 (Appendix A) presents the general boundaries and topography of the site on portions of the Salt Lake City North, Utah 1998 USGS topographic quadrangle map. Figure 2 is a site diagram, and Figures 3 and 4 indicate the approximate location of the excavation areas and confirmation sampling points in relation to the pertinent site features. 1.2 Project Background Four underground storage tanks (USTs), two 10,000-gallon gasoline and two 10,000-gallon diesel tanks, were installed at the site in 1987 to be used to fuel Salt Lake City fleet vehicles. The location of the former UST system within the site is shown on the site diagram (Figure 2). A suspected subsurface release of petroleum hydrocarbons originating from the area was reported to the Utah Division of Environmental Quality (UDEQ) Division of Environmental Response and Remediation (DERR) on July 8, 1993, when petroleum odors were noted during installation of tank system upgrades. The site was issued release ID IEQ. The release was attributed to periodic overfills when fueling vehicles. The USTs and associated pump island were excavated and removed from the site in September 2011. Closure samples collected during the removal of the USTs indicated petroleum hydrocarbons were still present at concentrations that exceeded DERR Initial Screening Levels and Tier 1 Screening Levels. Subsequent investigations identified petroleum impacts to soil and groundwater to extend beyond the tank basin. Petroleum-Impacted Soil Excavation Report Fleet Maintenance Yard ■ Salt Lake City, Utah November 20, 2014 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 2 Salt Lake City Corporation contacted IHI, a Terracon Company (Terracon), to conduct a limited subsurface investigation in August 2013 to evaluate soil and groundwater conditions in the vicinity of the former tank basin. Based on the information collected during that investigation, a Corrective Action Plan was designed to remediate impacted soils and submitted to the DERR on September 6, 2013. On October 7, 2013, Terracon collected groundwater samples from existing wells surrounding the former UST basin and dispenser areas to further evaluate the extent of groundwater impacts. Concentrations of dissolved petroleum constituents above Tier 1 Screening Levels were reported north and south of the UST basin. A copy of the report is included in Appendix B. Based on the data from the October 2013 groundwater sampling event, it was apparent that additional actions beyond the original Corrective Action Plan would be required to remediate the site to achieve regulatory closure. Terracon prepared Work Plan IEQ-15 (Terracon; December 17, 2013) to remediate soil and groundwater in the area of the former UST basin and dispensers (Figure 2) to allow unrestricted future use of the site and receive a “No Further Action” status for Release ID IEQ. 1.3 Scope of Work The corrective action approach was designed to remove impacted soils and remediate groundwater at the site to below DERR’s Initial Screening Levels for residential land use. The selected approach included removal of the impacted soils for off-site disposal and removal of 500-gallons of impacted groundwater from the open excavation, followed by limited application of chemical oxidation reagents to treat residual petroleum-impacted groundwater within the excavation area prior to backfilling. Terracon conducted the site work following the DERR-approved Work Plan IEQ-15. This report documents implementation of the Work Plan IEQ-15 during January and February of 2014. 1.4 Standard of Care Terracon’s services were performed in a manner consistent with generally accepted practices of the profession undertaken in similar studies in the same geographical area during the same time period.

SOIL REMEDIATION2.0 Terracon retained the services of a licensed, insured, and bonded environmental contractor, Direct Push Services LLC (DPS), to conduct soil excavation and remediation services. Excavated soil was field-screened using a photoionization detector (PID), along with olfactory and visual indications, to assist with defining the extent of the excavation of impacted soils. If a confirmation sample exceeded an ISL, excavation continued and additional confirmation samples were collected. The confirmation soil samples were collected in pre-cleaned containers provided by the laboratory, labeled, sealed, and preserved on ice through the time of delivery to a Utah-certified analytical laboratory using chain-of-custody protocols. Table 1 (Appendix C) displays the analytical results for confirmation soil samples. 2.1 Former UST Basin Excavation An initial excavation consisting of an approximate 97.5-foot long by 98-foot wide area was outlined in the area of the former UST basin. Soils were excavated and removed from the site to a depth of 10 feet below the ground surface (bgs). Excavation in this area required the removal of four on-site monitoring wells (MW-2, MW-3, PZ-3, and a 10-inch diameter slotted pipe within the UST basin), an oil/water separator, and a steel storm grate located within the UST basin excavation. Pea gravel impacted with petroleum hydrocarbons was discovered in the area of the former USTs to a depth greater than 10 feet bgs. Free product was discovered at the groundwater surface in the area of pea gravel and former USTs. As authorized by DERR, the free product Petroleum-Impacted Soil Excavation Report Fleet Maintenance Yard ■ Salt Lake City, Utah November 20, 2014 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 4 was removed with a vac trailer in addition to the sludge from the oil/water separator located within the former UST basin (500 gallons). With authorization from the DERR, Terracon directed DPS to dig deeper in the area of impacted pea gravel and a 40’ x 40’ concrete slab was found in the northwest quarter of the excavation at a depth of 10 to 10.5 feet bgs. The concrete pad formerly served as the anchor pad for the USTs located in the area, and apparently was not removed during the time of the UST removal. Since the concrete pad was located within the planned area of the excavation, it was mutually decided between the DERR and Terracon that the pad should be removed. Once the concrete was removed, free water was present within the area of the former USTs in the excavation bottom. At the request of the DERR, a 20,000 gallon frac tank was brought to the site to hold groundwater removed from the excavation. A total of 17,200 gallons of groundwater was removed from the excavation and treated by air sparging within the frac tank before being discharged through the onsite storm water system by approved permit obtained by the Division of Water Quality. Upon completion of initial excavation activities, Terracon collected confirmation soil samples to document petroleum hydrocarbon concentrations left in place (Figure 3). Confirmation soil samples were collected along the excavation walls with the samples labeled with the direction and a “W” to designate wall, and from the floor of the excavation, with the samples labeled with the letter “F” to designate “floor” and a number. Soil confirmation sampling indicated additional soil removal was required along the north wall of the excavation, as well as the floor in the northeast quadrant to remove impacted soils exceeding an ISL. Figure 3 shows the final extent of excavated soils. Both soil confirmation samples collected along the north wall of the excavation (NW-1 and NW- 2) had petroleum hydrocarbons reported at concentrations above ISLs. Terracon directed DPS to cut a trench north of the samples until PID readings decreased. The trench north of NW-1 was extended 15 feet north and the trench north of NW-2 was extended an additional five feet. The additional confirmation soil samples NW-3 (resample from NW-1) and NW-4 (resample of NW-2) had concentrations below ISLs. DPS removed the impacted soil along the north wall to the extent of the additional trenching Terracon collected soil confirmation sample FS-2 @ 10 feet bgs located in the northeast quarter of the excavation. The reported benzene concentration in the soil sample was above ISLs so Terracon directed DPS to remove an additional two feet of soil in this area until there was a color change and PID readings decreased. The resample (FS-2 @12’) was reported below ISLs for all constituents analyzed.

An approximate 3.5 foot x 7 foot area of soil was excavated to a total depth of 10 feet bgs and removed from the area surrounding PZ-1. Upon completion of excavation activities, Terracon collected one confirmation soil sample (PZ- 1) at a depth of 10 feet bgs from the excavation area to document petroleum hydrocarbon concentrations left in place (Figure 3). 2.3 MW-6 Excavation Area As impacted soils and groundwater were previously identified in the area of MW-6, soils were removed in the immediate area. An approximate 3.5 foot x 10 foot area of soil was excavated to a total depth of 10 feet bgs and removed from the area surrounding MW-6. Upon completion of excavation activities, Terracon collected one confirmation soil sample (MW- 6) at a depth of 10 feet bgs from the excavation area to document petroleum hydrocarbon concentrations left in place (Figure 3). 2.4 Soil Disposal A total of 6,027.7 tons of soil were transported to E.T. Technologies Soil Regeneration Site (SRS) in Salt Lake City with proper documentation. A copy of the weight tickets is included in Appendix D. GROUNDWATER REMEDIATION3.0 3.1 Vacuum-Enhanced Fluid Recovery DPS provided a vacuum trailer to remove impacted groundwater and free product from the excavation and water/sludge from the oil/water separator located within the tank excavation. Approximately 500 gallons of dissolved-phase, sludge, and free product were removed from the excavation and oil/water separator. The water was disposed at VJ Environmental. A copy of the disposal ticket is included in Appendix D. 3.2 Groundwater Confirmation Samples Once excavation activities were complete, Terracon collected groundwater samples from the open excavations. Groundwater samples were collected by excavating a pothole in the center of each of the four quadrants of the main excavation, and one in the center of both the PZ-1 and MW-6 excavations (Figure 4). Groundwater was allowed to infiltrate into the new pothole for a minimum of one hour, and a groundwater sample was collected directly into a clean laboratory Petroleum-Impacted Soil Excavation Report Fleet Maintenance Yard ■ Salt Lake City, Utah November 20, 2014 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 6 supplied- plastic bottle and immediately transferred to laboratory-supplied containers. Table 2 (Appendix B) displays the analytical results for confirmation groundwater samples. 3.3 Application of Hydrogen Peroxide To remediate the residual soil and groundwater contamination in the immediate vicinity of the excavation, a limited chemical oxidation event was implemented. Terracon directed Direct Push to apply two 55-gallon drums of a 35% solution of hydrogen peroxide directly into the groundwater at the bottom of the excavation, with the use of a barrel pump, and then hose-apply the solution to the target areas where residual contamination appeared most likely to remain. Once the hydrogen peroxide was applied, approximately 25 pounds of ferrous sulfate was broadcasted into the excavation in an effort to advance the chemical reaction. 3.4 Groundwater Management Depth to water in the excavation was measured between 9 to 10 feet bgs and was slow to recharge. In order to manage groundwater during excavation, groundwater encountered in the excavation was pumped into a 20,000-gallon holding tank. Approximately 17,200 gallons of groundwater in the holding tank was sparged for approximately 5 to 6 weeks from using compressed air. Once dewatering activities were complete, water samples were collected from the holding tank to evaluate the remaining petroleum hydrocarbons concentrations. Initially, the Work Plan called for the water to be discharged back into the excavation. Results from three sampling events determined that the water within the holding tank exceeded ISLs for groundwater and should not be discharged back into the excavation. An alternative solution for the disposal of the water within the tank was to discharge it to the nearest on-site storm water collection and discharge point. An UPDES construction dewatering permit was acquired from the Utah Division of Water Quality. A copy of the permit is included in Appendix E. ORPHANED UST4.0 During excavation of impacted soils, an orphaned UST was uncovered within the extent of the excavation (Figure 3). As the UST was not covered under the PST Fund or this Work Plan, it will not be fully documented in this report; however, the UST was reported to DERR, and a UST Closure Notice and UST Closure Plan were submitted to the DERR with proper UST removal sampling and protocols.

Fill material was placed in one foot lifts and compacted to 95% of a modified proctor. Based on future plans for site redevelopment, the surficial pavement was not restored. LABORATORY ANALYTICAL METHODS6.0 All soil and water samples were collected and placed in laboratory-prepared glassware and placed on ice in a cooler. The samples and completed chain-of-custody forms were hand- delivered to American West Analytical Laboratory in Salt Lake City, Utah, or shipped via overnight courier to Environmental Science Corporation analytical laboratory in Mt. Juliet, Tennessee (Utah-Certified Laboratories). The soil and groundwater samples collected from the excavation were analyzed by laboratory test methods as appropriate for the types of contaminants most likely to be encountered. This included methyl tertiary butyl ether, benzene, toluene, ethyl benzene, total xylenes and naphthalene (MBTEXN); total petroleum hydrocarbons – gasoline range organics (TPH-GRO); and total petroleum hydrocarbons – diesel range organics (TPH-DRO). Water samples collected from the holding tank were analyzed for MBTEXN, TPH-GRO, and TPH-DRO. To evaluate whether polar compounds generated by bacteria were skewing the TPH-DRO analytical results, two of the samples were additionally analyzed for TPH-DRO with silica gel cleanup to distinguish between polar compounds and diesel-range hydrocarbons, using Method 8015D Modified. The UPDES construction dewatering permit required analyses of oil and grease (O&G), pH, and total suspended solids (TSS) from the water within the holding tank. Samples were analyzed using the following methods: Analysis Sample Type No. of Samples Laboratory Method Soil Confirmation Results MBTEXN, TPH-GRO Soil 17 EPA Method 8260B TPH-DRO Soil 17 EPA Method 8015 Groundwater from Excavation Results MBTEXN, TPH-GRO Water 6 EPA Method 8260B TPH-DRO Water 6 EPA Method 8015 Groundwater in Holding Tank Petroleum-Impacted Soil Excavation Report Fleet Maintenance Yard ■ Salt Lake City, Utah November 20, 2014 ■ Terracon Project No. AL137118B Responsive ■ Resourceful ■ Reliable 8 Analysis Sample Type No. of Samples Laboratory Method MBTEXN, TPH-GRO Water 3 EPA Method 8260B TPH-DRO Water 3 EPA Method 8015 TPH-DRO w/Silica Gel Water 2 EPA Method 8015 Modified w/ Silica Gel O&G Water 1 EPA Method 1664 pH Water 1 SM4500-H+B TSS Water 1 Method SM2540D The executed chain-of-custody form and laboratory data sheets are provided in Appendix F. DATA EVALUATION7.0 7.1 Soil Confirmation Samples The reported soil concentrations were compared to screening levels promulgated by the DERR’s LUST Program. These include the conservative ISLs, and the somewhat less- conservative Tier 1 Screening Criteria that consider distance from residual contaminants to potential receptors. 7.2 Please refer to Table 1 (Appendix C) for a summary of all soil sample results and comparative regulatory screening levels. Figure 3 displays extent of excavation and soil sample locations. Former UST Basin The soil sample collected from confirmation soil sample NW-1 @ 10’ along the north wall of the excavation had TPH-GRO reported at 193 milligram per kilogram (mg/kg) which is above the ISL for TPH-GRO of 150 mg/kg. The confirmation soil sample NW-2 @ 9’ along the north wall of the excavation had TPH-DRO reported at 513 mg/kg which is above the ISL for TPH-DRO of 500 mg/kg. In addition, TPH-GRO was reported at 506 mg/kg which is above the ISL. The north wall was excavated an additional 5 to 15 feet to the north and confirmation samples were collected. Results from samples NW-3 @10’ and NW-4 @ 9’ indicated all impacted soil above an ISL was removed from the area. Confirmation soil sample FS-2 @ 10 feet bgs located on the floor in the northeast quarter of the excavation had a reported benzene concentration of 0.367 mg/kg which is above the benzene ISL of 0.2 mg/kg. Terracon directed DPS to remove an additional two feet of soil in this area until there was a color change and PID readings decreased. The resample collected (FS- 2@12’) was reported below ISLs for all constituents analyzed.

Petroleum impacts were not reported above an ISL. 7.4 MW-6 Excavation Area One soil sample was collected from the excavation area (MW-6 @10’). Petroleum impacts were not reported above an ISL. No other soil samples were reported above ISLs and/or laboratory reporting limits. 7.5 Groundwater Confirmation Samples The reported analyte concentrations were compared to the DERR ISLs and Tier 1 Screening Criteria for groundwater. Please refer to Table 2 (Appendix B) for a summary of all groundwater sample results and comparative regulatory screening levels. Based on the groundwater sample analytical results, it appears that dissolved concentrations of TPH-DRO, TPH-GRO, and benzene remain above an ISL in the UST basin. Benzene also exceeded the Tier 1 Screening Level in one sample (FS-3-GW). Dissolved concentrations of TPH-DRO also remain in both the PZ-1 and MW-6 excavation areas. Benzene was reported to exceed the ISL in the MW-6 area. 7.6 Holding Tank Water Samples Please refer to Table 3 (Appendix B) for a summary of analytical results and comparative regulatory screening levels, where applicable. The analytical results from grab samples collected from the holding tank on February 13 and 24, and on March 3, 2014, indicated that diesel-range hydrocarbons remained above the ISL. It was determined that the water in the holding tank should be discharged into the storm water system. The discharge permit required analyses for O&G, pH, and TSS. The analytical results indicated the water met the permitted concentration limits for discharge to the storm water system and the water was discharged on March 12, 2014 following all UPDES permit requirements.

This included removal and proper offsite disposal of over 6,000 tons of petroleum-contaminated soil; removal of an oil/water separator; removal and proper disposal of 500 gallons of associated sludge, free product, and impacted groundwater; removal and proper disposal of over 17,000 gallons of additional impacted groundwater; and limited application of chemical oxidation reagents to provide additional treatment of residual contaminants. With the source of groundwater contamination now removed, the residual impact to groundwater is expected to diminish. Based on the results of the confirmation soil samples, petroleum-impacted soils do not remain in the excavation areas at concentrations above ISLs. Diesel and gasoline range petroleum hydrocarbons, and benzene, remain in groundwater at the excavation area, above their respective ISLs. In addition, benzene concentrations from FS-3- GW exceeded the Tier 1 Screening Criteria. Terracon recommends conducting quarterly groundwater monitoring to evaluate groundwater quality conditions at the site. Since the source material has been removed, the hydrocarbons remaining in the groundwater will likely naturally attenuate. Once two consecutive quarters of groundwater results indicate dissolved petroleum hydrocarbons are below l ISLs, Terracon will request a “No Further Action” letter. GENERAL COMMENTS9.0 The behavior of subsurface contaminants is a complex phenomenon involving geochemistry, hydrogeology, and the geotechnical sciences. Terracon’s conclusions regarding the potential for subsurface contamination are based solely upon information cited in this report. The analyses and conclusions in this report are based upon data obtained from this assessment.

IHI additionally directed Direct Push Services to identify underground utilities at all borings locations using ground-penetrating radar prior to installing borings. 2.2 Subsurface Investigation The subsurface investigation was conducted by Mr. Jeff Kolmel, Utah-certified Soil and Groundwater Sampler (GS 1592), on August 15, 2013. DirectPush Services advanced eight borings to approximately fifteen feet below the ground surface (bgs), using direct-push drilling equipment. At each borehole location, soils were collected continuously, screened for the presence of volatile organic compounds (VOCs) using a photoionization detector (PID), and logged by an environmental scientist. One soil sample was collected from each boring at the depth with the greatest observed impacts (staining, petroleum odors, positive PID readings, etc.). A second soil sample was collected from four of the borehole locations with the highest observable impacts at the total depth of the borehole. The soil samples were submitted to ESC Lab Sciences, a Utah certified laboratory, for analysis of methyl tertiary-butyl ether, benzene, toluene, DERR – SLCC Fleet Yard UST 2 IHI Environmental LSI Report Project No. AL137118B ethylbenzene, total xylenes, and naphthalene (MBTEXN) and gasoline-range total petroleum hydrocarbons (TPH-GRO), using EPA Method 8260,and diesel-range total petroleum hydrocarbons (TPH-DRO), using EPA Method 8015. 3.0 RESULTS 3.1 Site Lithology and General Observations Subsurface soils encountered during the subsurface investigation generally consisted of sandy gravel fill underlain by silty sand, sand, clayey sand, and dense clay. Significant amounts of asphalt material were observed in the fill material to depths of six to ten feet bgs. Lithologic boring logs are presented in Appendix 1. In general, evidence of significant petroleum impacts was observed in the boreholes located directly south and southeast of the former dispenser islands between seven and twelve feet bgs. Groundwater was encountered between 7.5 and 9.5 feet bgs. The calculated groundwater flow direction based on the groundwater monitoring conducted at the site is to the south / southeast. 3.2 Subsurface Investigation Soil Sample Results Table 1 summarizes the soil sample analytical results for the subsurface investigation. Included in Table 1 are the Initial Screening Levels (ISLs) and Tier 1 screening levels established by the Utah DEQ’s UST Program. Sample locations are shown on Figure 1. Laboratory analytical results are included in Appendix 2.

Bold values exceed ISLs. As shown in Table 1, the soil samples collected from the impacted zone at B-1, B-2, B-3, and B-4 contained various hydrocarbon constituents at concentrations exceeding the ISLs. The sample collected from the impacted zone at B-2 contained concentrations of TPH-DRO and benzene that exceed the Tier 1 Screening Levels. The sample collected from the impacted zone at B-3 contained concentrations of TPH-GRO and benzene that exceed the Tier 1 Screening Levels. Although all of the remaining samples contained reportable concentrations of petroleum hydrocarbons, the concentrations reported were below the ISLs. 3.3 Quality Assurance / Quality Control To maintain quality control during sampling activities, all soil samples were collected in laboratory-supplied sample containers and were maintained in an iced cooler under proper chain-of-custody protocol until delivered to the analytical laboratory. Quality control was provided by using standardized sample collection and handling methods, documenting pertinent field information, keeping chain-of-custody records, and using a Utah-certified laboratory. DERR – SLCC Fleet Yard UST 4 IHI Environmental LSI Report Project No. AL137118B The analytical laboratory report indicated that samples were extracted and analyzed within the appropriate sample holding times. Although the laboratory qualified some results, the nature of the qualification does not preclude using the data for its intended purpose. 4.0 SUMMARY 4.1 Soil Impacts The analytical results of this limited subsurface investigation indicate that petroleum- impacted soil exceeding ISLs and Tier 1 Screening Levels is present between seven and twelve feet bgs to the south and southeast of the former dispenser islands. Due to the high concentrations of TPH-DRO and benzene reported in the sample collected from B-2, it is likely that impacts extend beyond the investigation area to the south and southeast.

BOLD values exceed ISLs. DERR – SLCC Fleet Yard UST 5 IHI Environmental LSI Report Project No. AL137118B These samples indicate that the main soil impacts may originate from the dispenser islands. Three of the four confirmation samples collected at 7 feet bgs at the dispenser islands contained petroleum impacts above action limits. 5.0 DISCUSSION It is IHI’s professional opinion that source reduction by over-excavation of the petroleum- impacted soil will allow the remaining soil impacts and the groundwater impacts to naturally attenuate, thereby allowing unrestricted land-use for property redevelopment. Because of the multitude of underground utilities located within 30 feet of the impacted soil and groundwater, IHI proposes using ISLs as the action limits during remediation. Based on the results of the current and previous limited site investigations, IHI proposes over-excavating the north and south dispenser island areas, as well as the area southwest of the former south dispenser island encompassed by sample locations B-1, B-2, B-3, and B-4. A map of the proposed excavation area is presented as Figure 2. The north and south dispenser island areas will be excavated to a depth of approximately twelve feet bgs. In order to minimize the amount of impacted soil requiring disposal, in the area southwest of the former dispenser islands, the top six to seven feet of soil will be excavated and stockpiled on site. Following the removal of clean material, the remaining petroleum-impacted soil will be excavated to a depth of approximately twelve feet bgs. Following excavation activities, the floor and walls of the excavation area will be screened with a PID, and confirmation samples will be collected to ensure that the remaining impacts are below the Action Limits. The petroleum-impacted soil will be transported to the E T technologies Soil Regeneration facility for treatment. 6.0 PROJECT LIMITATIONS This Project was performed using, as a minimum, practices consistent with standards acceptable within the industry at this time, and a level of diligence typically exercised by environmental consultants performing similar services. The procedures used attempt to establish a balance between the competing goals of limiting investigative and reporting costs and time, and reducing the uncertainty about unknown conditions. Therefore, because the findings of this report were derived from the scope, costs, DERR – SLCC Fleet Yard UST 6 IHI Environmental LSI Report Project No. AL137118B time and other limitations, the conclusions should not be construed as a guarantee that all environmental liabilities have been identified and fully evaluated. Where sample collection and testing have been performed, IHI's professional opinions are based in part on the interpretation of data from discrete sampling locations that may not represent conditions at non-sampled locations. Furthermore, IHI assumes no responsibility for omissions or errors resulting from inaccurate information, or data, provided by sources outside of IHI or from omissions or errors in public records. It is emphasized that the final decision on how much risk to accept always remains with the client since IHI is not in a position to fully understand all of the client's needs. Clients with a greater aversion to risk may want to take additional actions while others, with less aversion to risk, may want to take no further action.

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 control 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 "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 method limit, the effected samples are flagged with a "J3" qualifier.

Confidence correlates with concentration. T2 (ESC) - Additional method/sample information: The laboratory analysis was from an unpreserved or improperly preserved sample. 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.

The quality control 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 "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 method limit, the effected samples are flagged with a "J3" qualifier. Page 10 of 10 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. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The quality control 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 "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 method limit, the effected samples are flagged with a "J3" qualifier.
