2 CASE NARRATIVE Client: Dawson Technical, LLC Project: Joint Base Cape Cod Report Number: With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 05/26/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was C. VOLATILE ORGANIC COMPOUNDS (GC-MS) Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for volatile organic compounds (GC-MS) in accordance with EPA SW-846 Method 8260B. The samples were prepared on 05/25/2016 and analyzed on 06/07/2016. Several compounds were outside control limits in the continuing calibration verification (CCV) standards. These compounds are not classified as Calibration Check Compounds (CCCs) in the reference method. The responses were elevated, and the compounds were not detected in the associated samples. The analyses of samples J2_WC_052516_03, J2_WC_052516_06 and J2_WC_052516_07 yielded elevated recoveries for surrogates toluene-d8 and/or 4-bromofluorobenzene. These samples did not contain any target analytes; therefore, re-analysis was not performed. The data has been qualified and reported. The original analysis of sample J2_WC_052516_04 yielded low surrogate recoveries. The sample was reanalyzed with concurring results. Both sets of data have been reported in this case submittal. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. SEMIVOLATILE ORGANIC COMPOUNDS (GC-MS) Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for semivolatile organic compounds (GC-MS) in accordance with EPA SW-846 Method 8270C. The samples were prepared on 06/01/2016 and analyzed on 06/09/2016 and 06/10/2016. A matrix spike performed on sample J2_WC_052516_01 yielded low recovery of 3,3'-dichlorobenzidine. The matrix spike duplicate yielded low recovery of 3,3'-dichlorobenzidine and 4-chloroaniline. 4-Chloroaniline and Aniline exceeded the RPD limit. The blank spike sample was acceptable. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GASOLINE RANGE ORGANICS (GRO) Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for gasoline range organics (GRO) in accordance with EPA SW-846 Method 8015B - GRO. The samples were analyzed on 06/06/2016 and 06/07/2016. Samples J2-WC and J2-WC were field preserved with methanol by method 5035, however the samples absorbed all of the available methanol. These samples were then lab preserved by method The analyses of samples J2_WC_052516_02, J2_WC_052516_07 and J2_WC_052516_09 yielded elevated surrogate recoveries. Re-analyses were performed with concurring results. The original analyses have been reported. The analysis of sample J2_WC_052516_01 yielded marginally low surrogate recovery. The sample had a high % moisture content of which diluted the MeOH added in the preparation; therefore, re-extraction was not performed. Page 2 of 258

3 Matrix spikes performed on sample J2_WC_052516_05 yielded low recovery of Gasoline Range Organics (GRO)-C6-C10. The blank spike sample was acceptable. The Gasoline Range Organics (GRO) concentration reported for samples J2_WC_052516_03, J2_WC_052516_05, J2_WC_052516_06 and J2_WC_052516_07 is due to the presence of discrete peaks rather than a GRO pattern. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. DIESEL RANGE ORGANICS Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for diesel range organics in accordance with 8015B_DRO. The samples were prepared on 06/06/2016 and analyzed on 06/08/2016. Diesel Range Organics [C10-C28] was detected in method blank MB /1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. The analyses of samples J2_WC_052516_03, J2_WC_052516_05, J2_WC_052516_07 and J2_WC_052516_09 yielded elevated recovery of surrogate n-octacosane and acceptable recovery of o-terphenyl. Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed. A matrix spike duplicate performed on sample J2_WC_052516_07 yielded slightly elevated recovery of Diesel Range Organics [C10-C28]. The matrix spike and blank spike sample were acceptable. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PESTICIDES Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for Pesticides in accordance with 8081B. The samples were prepared on 06/06/2016 and analyzed on 06/09/2016, 06/10/2016 and 06/11/2016. delta-bhc was detected in method blank MB /1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. The analyses of the samples in this delivery group yielded the presence of numerous non-target peaks and significant baseline rises that could be interfering with the identification and quantitation of target analytes. This inference could cause false positive and/or negative results. The original analyses of the samples in this delivery group were follwed with a calibration Verification standard that was outside control criteria for 4,4-DDD, 4,4-DDT and Methoxychlor due to suspected matrix affect from the samples. The laboratory re-analyzed these samples at dilutions to minimize the matrix effect, resulting in a acceptable calibration verification standard. 4,4-DDD, 4,4-DDT and Methoxychlor are reported from the dilution analyses. Surrogate recoveries were impacted in the dilution analyses. Sample J2_WC_052516_02 was only analyzed at dilution due to the presence of numerous non-target peaks and significant baseline rise that could be interfering with the identification and quantitation of target analytes. This inference could cause false positive and/or negative results, and was mitigated with dilution. Surrogate spikes were diluted below calibration level in that analysis. Several samples yielded low recovery of one of the two surrogates and acceptable recovery of the other surrogate. Sample J2_WC_052516_05 yielded marginally low recovery of both surrogates. Note that there is an in house variance that allows for the recovery limits to be % for tetrachloro-m-xylene. A matrix spike duplicate performed on sample J2_WC_052516_03 yielded low recovery for several compounds, and several analytes exceeded the RPD limit. The blank spike sample was acceptable. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PCB AROCLORS Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for PCB Aroclors in accordance with 8082A. The samples were prepared on 06/06/2016 and analyzed on 06/08/2016. A matrix spike duplicate performed on sample J2_WC_052516_04 yielded elevated recovery of aroclor The blank spike sample was acceptable. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. ORGANOCHLORINE HERBICIDES Samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, Page 3 of 258

4 J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 were analyzed for organochlorine herbicides in accordance with EPA SW-846 Method 8151A. The samples were prepared on 06/07/2016 and 06/08/2016 and analyzed on 06/12/2016 and 06/14/2016. Matrix spikes performed on sample J2_WC_052516_06 yielded low recoveries for several compounds. The blank spike samples were acceptable with the exception of marginally low recovery of dichlorprop. The TestAmerica Denver DoD QSM Variance requests include a widening of %R for Dichlorprop in soils from %R (DoD) to %R. Dichlorprop has been identified as a poor performing analyte when analyzed using this method and the LCS recovered within the widened windows; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified. The orginal analysis of samples J2_WC_052516_01, J2_WC_052516_02, J2_WC_052516_03, J2_WC_052516_04, J2_WC_052516_05, J2_WC_052516_06, J2_WC_052516_07, J2_WC_052516_08 and J2_WC_052516_09 clogged the syringe on the instrument.

260 CASE NARRATIVE Client: Dawson Technical, LLC Project: Joint Base Cape Cod Report Number: With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 05/26/2016; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was C. SEMIVOLATILE ORGANIC COMPOUNDS (GC-MS) Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for semivolatile organic compounds (GC-MS) in accordance with EPA SW-846 Method 8270C. The samples were prepared on 06/01/2016 and analyzed on 06/10/2016. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. DIESEL RANGE ORGANICS Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for diesel range organics in accordance with 8015B_DRO. The samples were prepared on 06/06/2016 and analyzed on 06/08/2016. Diesel Range Organics [C10-C28] was detected in method blank MB /1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GASOLINE RANGE ORGANICS (GRO) Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for gasoline range organics (GRO) in accordance with 8015D GRO. The samples were prepared on 05/25/2016 and analyzed on 06/07/2016. The Gasoline Range Organics (GRO) concentration reported for sample U_WC_052516_02 is due to the presence of discrete peaks rather than a GRO pattern. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PESTICIDES Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for Pesticides in accordance with 8081B. The samples were prepared on 06/06/2016 and analyzed on 06/10/2016 and 06/11/2016. delta-bhc was detected in method blank MB /1-A at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. The analyses of the samples in this delivery group yielded the presence of numerous non-target peaks and significant baseline rises that could be interfering with the identification and quantitation of target analytes. This inference could cause false positive and/or negative results. The original analyses of the samples in this delivery group were follwed with a calibration Verification standard that was outside control criteria for 4,4-DDD, 4,4-DDT and Methoxychlor due to suspected matrix affect from the samples. The laboratory re-analyzed these Page 2 of 123

261 samples at dilutions to minimize the matrix effect, resulting in a acceptable calibration verification standard. 4,4-DDD, 4,4-DDT and Methoxychlor are reported from the dilution analyses. Surrogate recoveries were impacted in the dilution analyses. Several samples yielded low recovery of one of the two surrogates and acceptable recovery of the other surrogate. Note that there is an in house variance that allows for the recovery limits to be % for tetrachloro-m-xylene. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PCB AROCLORS Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for PCB Aroclors in accordance with 8082A. The samples were prepared on 06/06/2016 and analyzed on 06/08/2016. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. ORGANOCHLORINE HERBICIDES Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for organochlorine herbicides in accordance with EPA SW-846 Method 8151A. The samples were prepared on 06/07/2016 and analyzed on 06/14/2016. The blank spike sample yielded acceptable recoveries with the exception of marginally low recovery of dichlorprop. The TestAmerica Denver DoD QSM Variance requests include a widening of %R for Dichlorprop in soils from %R (DoD) to %R. Dichlorprop has been identified as a poor performing analyte when analyzed using this method and the LCS recovered within the widened windows; therefore, re-extraction/re-analysis was not performed. The results have been reported and qualified. The orginal analyses of the samples in this delivery group clogged the syringe on the instrument. These samples were re-analyzed at dilutions yielding acceptable results. The reporting limits have been adjusted accordingly. Sample U_WC_052516_01 was extracted with approximately half the routine sample mass due to the limited amount of sample available. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. EXPLOSIVES Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for explosives in accordance with EPA SW-846 Method 8B. The samples were prepared on 06/07/2016 and analyzed on 06/15/2016. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. PERCHLORATE Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for perchlorate in accordance with EPA SW The samples were leached on 06/08/2016 and analyzed on 06/10/2016. The perchlorate analyses of the samples in this delivery gruop were prepared using pre-dried sample. The analytical results are inherently on a dry weight basis. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. METALS (ICP) Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for Metals (ICP) in accordance with 6010C. The samples were prepared on 06/01/2016 and analyzed on 06/02/2016 and 06/03/2016. Barium and Chromium were detected in method blank MB /1-A at levels that were above the method detection limit but below the reporting limit. The values should be considered estimates, and have been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. MERCURY Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for mercury in accordance with 7471B. The samples were prepared and analyzed on 05/31/2016.

IGNITABILITY FOR SOLIDS Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for ignitability for solids in accordance with EPA SW-846 Method The samples were analyzed on 06/13/2016. The samples in this delivery gruop did not ignite; therefore, an ignitability value could not be obtained. The results have been reported as "No Burn" (NB). No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Page 3 of 123

262 SPECIFIC CONDUCTIVITY Samples U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for specific conductivity in accordance with SM B. The samples were leached on 06/17/2016 and analyzed on 06/17/2016. It was not possible to analyze sample U_WC_052516_01 for conductivity, as the lab had consumed all of the available sample mass before the request to analyze for conductivity was made. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. CYANIDE Samples U_WC_052516_01, U_WC_052516_02, U_WC_052516_03 and U_WC_052516_04 were analyzed for cyanide in accordance with 9012B. The samples were prepared and analyzed on 06/07/2016.
