October, 2018 through September, 2019

Appendix A Interlaboratory/ Intralaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratorys analytical procedures and to alert it of any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

Results in Table A-1 were obtained through participation in the RAD PT Study Proficiency Testing Program administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

Table A-2 lists results for thermoluminescent dosimeters (TLDs), via irradiation and evaluation by the University of Wisconsin-Madison Radiation Calibration Laboratory at the University of Wisconsin Medical Radiation Research Center.

Table A-3 lists results of the analyses on in-house spiked samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house blank samples for the past twelve months. Data for previous years available upon request.

Table A-5 lists analytical results from the in-house duplicate program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors.

Complete analytical data for duplicate analyses is available upon request.

The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.

Results in Table A-7 were obtained through participation in the MRAD PT Study Proficiency Testing Program administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).

Attachment A lists the laboratory acceptance criteria for various analyses.

Out-of-limit results are explained directly below the result.

Results obtained by Environmental, Inc., Midwest Laboratory as a participant in the crosscheck program for proficiency testing in drinking water conducted by Environmental Resource Associates (ERA).

b In order to get to the root cause of the above "Fail" resolution the U-232 tracer was standardized using a known concentration of NIST U-238 solution. A duplicate analysis was performed and the results obtained were well within the acceptance range (Known value for Total Uranium=68.2 pCi/L, acceptance range of (55.7-75 pCi/L). The results obtained were 63.3 pCi/L and 66.0 pCi/L respectively.

c The standardized U-232 value utilized on ERA sample ERW-75 (see footnote "b" above was found to be estimated high due to interferences in the U-238 solution causing the ERW-1141 Uranium PT failure above. After performing U-isotopic chemistry on the NIST-Uranium solution to remove interferences a more accurate U-232 tracer concentration was obtained. The subsequent ERA PT study was acceptable. See ERW-2477 Uranium result above.

d H-3 analysis was performed using the ERA provided blank sample. Pairing the ERA supplied blank and the lab routine blank with standard vials created confusion and resulted in the standard total count time being mistallied by half.

The resulting batch efficiency was overstated by a factor of two and the reported ERA results were understated by half.

The result of reanalysis, (17,400 pCi/L), is within the control limits for the study.

Liquid sample results are reported in pCi/Liter, air filters ( pCi/m3), charcoal (pCi/charcoal canister), and solid samples (pCi/kg).

b Laboratory codes : W & SPW (Water), MI (milk), AP (air filter), SO (soil), VE (vegetation), CH (charcoal canister), F (fish), U (urine).

c Results are based on single determinations.

d Control limits are listed in Attachment A of this report.

e The LCS sample was prepared from an Environmental Resource Associates (ERA) sample of known activity. While the analysis did satisfy the acceptance criteria of the ERA study from which it was sourced, it did not satisfy EIML's internal LCS acceptance criteria. All of the original solution had been consumed in the analysis. Subsequent gross alpha and beta PT and LCS sample results were acceptable.

NOTE: For fish, gelatin is used for the spike matrix. For vegetation, cabbage is used for the spike matrix.

Results are reported in units of Bq/kg (soil), Bq/L (water) or Bq/total sample (filters, vegetation).

b Laboratory codes as follows: MAW (water), MAAP (air filter), MASO (soil) and MAVE (vegetation).

c MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive". MAPEP does not provide control limits.

d Provided in the series for "sensitivity evaluation". MAPEP does not provide control limits.

e An investigation is in progress to determine the reason for the failure of the Pu-239 study.

f An erroneous volume conversion caused some incorrect values to be submitted. If the conversion had been performed properly the results in Bq/sample would have been (Sr-90: 0.671 +/- 0.066 ) and (U-234: 0.153 +/- 0.036) and (U-238: 0.144 +/- 0.035).

This result had been included in the Uranium investigation. See footnote "C" on Table A-1.

APPENDIX B DATA REPORTING CONVENTIONS

Data RepQOlng Conventions 1.0. All actM!les, except gross alpha and gross beta, are decay corracted to collsction time or the end of the collection period.

2.0. Single Measurements Each slngle measurement is reported as follows: x ts where: x "' value of the measurement; s = 2o counting uncertainty {corresponding to the 96% confidence level).

In cases where the activity is less than the lower llmft of detedlon L, ii is reported as: < L, where L c the lower limit of detectlon based on 4.660" uncertainty for a background sample.

3.0. Duplicate anatyses If dupllcate analyse$ are reported, the canventlon is ~s follows.:
