CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-1 01 U Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Pneumatic Test Dates: 9/15/2013; 9/16/2013 Well Construction Diagram Plots:

  • Background water level for rising head test
  • Rising head test
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 101 UBR 2013-09-15 10-52.44 (contains background and pressurization/equalization data for rising head test)
  • 101 UR 2013-09-15 10.49.20 (contains test data for rising head test)
  • 101 UBF 2013-09-16 10.43.51 (contains background and vacuum/equalization data for falling head test)
  • 101UF 2013-09-16 14.04.03 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing = 20.84 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point. *
4. Water level changes during tests are represented by changes in the height of water above the transducer.

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing= 60.74 ft
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

  • Falling head test
  • Background water level for rising head test
  • Rising head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.

  • 202LR 2013-10-2 07.29.44 (contains test data for rising head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background" file prior to initiating a test. For this test, an unexplained increase in water level between ending the background check and starting the falling head test occurred. The data for the background file is considered questionable. AMEC recommends using the portion of the falling head test file immediately prior to the slug insertion to obtain the reference head for the test analysis.
2. Static water level (below top of casing) prior to testing =48.21 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
5. A pneumatic test was attempted, but the well was not holding pressure.

The test method was changed to the solid slug method. Prepared by/Date: f2:M 4/.i ),a-Checked by/Date: C!"PT?! ,/c;/19-Clinch River Data Report Rev. 4 CRP-1112.16 Page E.4-23 of 185

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background file prior to initiating a test.
2. Static water level (below top of casing) prior to testing =55.77 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
5. A pneumatic test wa~ attempted, but the well was not holding pressure.

The test method was changed to the solid slug method. Prepared by/Date: k:b\L l/JD/IL( Checked by/Date:Yhj 1}1} 14-

  • Background water level for rising head test
  • Rising head test
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 401 LBR 2013-09-17 09.56.10 (contains background and pressurization/equalization data for rising head test)
  • 401LR 2013-09-1710.35.04 (contains test data for rising head test)
  • 401 LBF 2013-09-17 11.43.44 (contains background and vacuum/equalization data for falling head test)
  • 401 LF 2013-09-17 12.35.49 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
                                                                                           =
2. Static water level (below top of casing) prior to testing 40.46 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background file prior to initiating a test.
2. Static water level (below top of casing) prior to testing = 64.70 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
5. Background for rising head test is last portion of falling head test which was allowed to continue overnight due to very slow well response.

CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-416L Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Pneumatic Test Dates: 9/29/2013 Well ~onstruction Diagram Plots:

  • Background water level for rising head test
  • Rising head test
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 416LBR 2013-09-29 11.53.19 (contains background and pressurization/equalization data for rising head test)
  • 416LR 2013-09-29 12.02.29 (contains test data for rising head test)
  • 416LBF 2013-09-29 12.38.02 (contains background and vacuum/equalization data for falling head test)
  • 416LF 2013-09-29 12.57.07 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing = 72.08 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

  • Background water level for rising head test
  • Rising head test
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 417UBR 2013-09-19 09.49.25 (contains background and pressurization/equalization data for rising head test)
  • 417UR 2013-09-19 09.46.58 (contains test data for rising head test)

  • 417U F 2013-09-19 10.41.42 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing =28.02 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

  • Background water level for rising head test
  • Rising head test
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 418UBR 2013-09-28 14.10.21 (contains background and pressurization/equalization data for rising head test)
  • 418UR 2013-09-28 15.13.03 (contains test data for rising head test)

  • 418UF 2013-09-2817.16.39 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing =61.92 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

  • Background water level for rising head test No. 2
  • Rising head test ~o. 2
  • Background water level for falling head test
  • Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 419UBR2 2013-09-25 15.08.28 (contains background and pressurization/equalization data for rising head test No. 2)
  • 419UR2 2013-09-25 15.15.39 (contains test data for rising head test No. 2)
  • 419UBF 2013-09-25 15.59.50 (contains background and vacuum/equalization data for falling head test)
  • 419UF 2013-09-25 16.01.04 (contains test data for falling head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.
2. Static water level (below top of casing) prior to testing =46.70 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
5. Initial rising head test rejected and re-run as Rising Head Test 2. Files from initial test not included or plotted.

  • Background water level for rising head test (pneumatic slug)
  • Rising head test (pneumatic slug)
  • Background water level for falling head test (solid slug)
  • Falling head test (solid slug)
  • Background water level for rising head test (solid slug)
  • Rising head test (solid slug)

Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.

  • 420LBR pneumatic2013-09-30 16.16.58 (contains background and pressurization/equalization data for pneumatic slug rising head test)
  • 420LR pneumatic2013-09-30 18.12.00 (contains test data for pneumatic slug rising head test
  • 420LBF2 2013-10-01 14.36.54 (contains background data for falling head test)
  • 420LF2 2013-10-01 16.55.20 (contains test data for falling head test)

  • 420LR 2013-10-02 11.40.13 (contains test data for rising head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted for pneumatic tests.
                                                                                         =
2. Static water level (below top of casing) prior to testing 64.88 ft on 9/30/13 and 64.77 ft on 10/1/13.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
5. The well would not hold a vacuum; the test method was changed to the solid slug method, and the transducer was lowered to accommodate the solid slug.

  • Background water level for falling head test
  • Falling head test
  • Background water level for rising head test
  • Rising head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 421LBF 2013-10-02 10.43.09 (contains background data for falling head test)
  • 421 LF 2013-10-08 09.02.23 (contains test data for falling head test)
  • 421LBR 2013-10-09 10.01.35 (contains background data for rising head test)
  • 421LR 2013-10..:14 08.43.27 (contains test data for rising head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background file prior to initiating a test.
2. Static water level (below top of casing) prior to testing =70.61 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.

CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-429U Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Solid Test Dates: 11/19/2013; 11/20/2013 Well Construction Diagram Plots:

  • Background water level for falling head test
  • Falling head test
  • Background water level for rising head test
  • Rising head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data.
  • 429UBGF 2013~11~19 08.37.46 (contains background data for falling head test)
  • 429UF 2013~11-19 08.38.25 (contains test data for falling head test)
  • 4.29UBGR 2013-11-19 08.38.38 (contains background data for rising head test)
  • 429UR 2013-11-20 08.40.53 (contains test data for rising head test)

Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background file prior to initiating a test.
2. Static water level (below top of casing) prior to testing =37.15 ft.
3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.
4. Water level changes during tests are represented by changes in the height of water above the transducer.
