1. Introduction GEL Laboratories, LLC (GEL) is a privately owned environmental laboratory dedicated to providing personalized client services of the highest quality. GEL was established as an analytical testing laboratory in 1981. Now a full service lab, our analytical divisions use state of the art equipment and methods to provide a comprehensive array of organic, inorganic, and radiochemical analyses to meet the needs of our clients.

At GEL, quality is emphasized at every level of personnel throughout the company.

Management's ongoing commitment to good professional practice and to the quality of our testing services to our customers is demonstrated by their dedication of personnel and resources to develop, implement, assess, and improve our technical and management operations. ,

The purpose of GEL's quality assurance program is to establish policies, procedures, and processes to meet or exceed the expectations of our clients. To achieve this, all personnel that support these services to our clients are introduced to the program and policies during their initial orientation, and annually thereafter during company-wide training sessions.

GEL's primary goals are to ensure that all measurement data generated are scientifically and legally defensible, of known and acceptable quality per the data quality objectives (DQOs),

and thoroughly documented to provide sound support for environmental decisions. In addition, GEL continues to ensure compliance with all contractual requirements, environmental standards, and regulations established by local, state and federal authorities.

GEL administers the QA program in accordance with the Quality Assurance Plan, GL-QS-B-001. Our Quality Systems include all quality assurance (QA) policies and quality control (QC) procedures necessary to plan, implement, and assess the work we perform. GEL's QA Program establishes a quality management system (QMS) that governs all of the activities of our organization.

This report entails the quality assurance program for the proficiency testing and environmental monitoring aspects of GEL for 2016. GEL's QA Program is designed to monitor the quality of analytical processing associated with environmental, radiobioassay, effluent (10 CFR Part 50),

and waste (10 CFR Part 61) sample analysis.

I This report covers the category of Radiological Environmental Monitoring Program (REMP) and includes: *

Intra-laboratory QC results analyzed during 2016.

Inter-laboratory QC results analyzed during 2016 where known values were available.

2. Quality Assurance Programs for Inter-laboratory, Intra-laboratory and Third Party Cross-Check In addition to internal and client audits, our laboratory participates in annual performance evaluation studies conducted by independent providers. We routinely participate in the following types of performance audits:

Proficiency testing and other inter-laboratory comparisons

Performance requirements necessary to retain Certifications

Evaluation of recoveries of certified reference and in-house secondary reference materials using statistical process control data.

Evaluation of relative percent difference between measurements through SPC data.

We also participate in a number of proficiency testing programs for federal and state agencies and as required by contracts. It is our policy that no proficiency evaluation samples be analyzed in any special manner. Our annual performance evaluation participation generally includes a combination of studies that support the following:

US Environmental Protection Agency Discharge Monitoring Report, Quality Assurance Program (DMR-QA). Annual national program sponsored by EPA for laboratories engaged in the analysis of samples associated with the NPDES monitoring program. Participation is mandatory for all holders of NPDES permits. The permit holder must analyze for all of the parameters listed on the discharge permit. Parameters include general chemistry, metals, BOD/COD, oil and grease, ammonia, nitrates, etc.

Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP). A semiannual program developed by DOE in support of DOE contractors performing waste analyses. Participation is required for all laboratories that perform environmental analytical measurements in support of environmental management activities. This program includes radioactive isotopes in water, soil, vegetation and air filters.

ERA's MRAD-Multimedia Radiochemistry Proficiency test progr?m. This program is for

/labs seeking certification for radionuclides in wastewater and solid waste. The program is conducted in strict compliance with USEPA National Standards for Water Proficiency study.

ERA's lnterlaB RadCheM Proficjency Testing Program for radiological analyses. This program completes the process of replacing the USEPA EMSL-L\/ Nuclear Radiation Assessment Division program discontinued in 1998. Laboratories seeking certification for radionuclide analysis in drinking wa!er also use the study. This program is conducted in

P.O. Box 30712, Charleston, SC 29417 2016 ANNUAL QUALITY ASSURANCE REPORT Page 7 of60 strict compliance with the USEPA National Standards for Water Proficiency Testing Studies. This program encompasses Uranium by EPA method 200.8 (for drinking water certification in Utah/Primary NELAP), gamma emitters, Gross Alpha/Beta, lodine-131, naturally occurring radioactive isotopes, Strontium-89/90,_and Tritium.

ERA's Water Pollution (WP) biannual program for waste methodologies includes parameters for both organic and inorganic analytes.

. ERA's Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.

Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, Inc. This program encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.

GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify the analysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GEL's Third-Party Cross-Check Program provides environmental matrices encountered in a typical nuclear utility REMP. The Third-Party Cross-Check Program is intended to meet or exceed the inter.:laboratory comparison program requirements discussed in NRC Regulatory Guide 4.15. Once performance evaluation samples have been 'prepared in accordance with the instructions provided by the PT provider, samples are managed and analyzed in the same manner as environmental samples from GEL's clients.

3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment of each area of the laboratory is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E-001. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program. Internal audits are conducted at least annually in accordance with a schedule approved by the Quality Systems Director. Supplier audits are contingent upon the categorization of the supplier, and may or may not be conducted prior to the use of a.supplier or subcontractor. Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years.

In addition, prospective customers audit GEL during pre.,contract audits. GEL hosts several external audits each year for both our clients and other programs. These programs include environmental monitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL at least annually or up to every three years depending on the program.

The annual radiochemistry laboratory internal audit (16-RAD-001) was conducted in May, 2016. Two (2) findings, six (6) observations, and five (5) recommendation resulted from this assessment. By July, 2016, the findings were closed and appropriate laboratory staff addressed each observation and recommendation.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (i.e., MAPEP, and ERA/ELAP), GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.

5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of any one result from the known value. The second criterion concerns precision, which *deals with the ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.

At GEL, we also evaluate our analytical performance on a regular basis through statistical process control (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.

For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GEL's AlphaLIMS. We also measure precision with matrix duplicates and/or matrix spike duplicates.

The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences.

The static precision criteria for radiochemical analyses are O - 20%, for activity levels exceeding the contract required detection limit (CRDL).

6. Quality Control Program for Environmental Sample Analysis GEL's internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response}, blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control and qualification analyses samples are used to be as similar as the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples (or performance evaluation samples) are either actual sample submitted in duplicate in order to evaluate the precision of laboratory measurements, or J

Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for most radiochemical analyses is 75 - 125%. Specific instructions for oµt-of-control situations are provided in the applicable analytical SOP.

GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.

Some _methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking water matrix.

Bias(%)= (observed concentration)

100 %

(known concentration)

Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves.

Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.

GEL's laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is analyzed independently from the parent sample and the results are compared to measure precision and accuracy.

If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPO). The RPO must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPO must be equal to or less than 100%. If one result is above the MDC and the other is below the MDC, then the RPO can be calculated using the MDC for the result of the one below the MDC. The RPO must be 100% or less: In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC,_ the RPO must be less than or equal to 20%.

If both results are below MDC, then the limits on,% RPO are not applicable.

Difference(%) = (high duplicate result- low duplicate result)

7. Summary of Data Results -

During 2016, fifty-five (55) radioisotopes associated with seven (7) matrix types were analyzed under GEL's Performance Evaluation program in participation with ERA, MAPEP, and Eckert

& Ziegler Analytics. Matrix types were representative of client analyses performed during 2016. Of the five hundred one (501) total results, 98.6% (494 of 501) were found to be acceptable within the PT providers three sigma or other statistical criteria. The list below contains the type of matrix evaluated by GEL.

8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program

Eckert & Ziegler Analytics provided samples for one hundred twenty-eight (128) individual

environmental analyses. The accuracy of each result reported to Eckert & Ziegler Analytics, Inc. is measured by the ratio of GEL's result to the known value. All results fell within GEL's acceptance criteria (100% within acceptance).

9. Summary of Participation in the MAPEP Monitoring Program MAPEP Series 34 and 35 were analyzed by'the laboratory One hundred twenty six (126) of the 128 analyses fell within the PT provider's acceptance criteria (98.4% within acceptance).

Two unacceptable results were reported: lron-55 and Radium-226.

The corrective actions associated with these results were documented in CARR160602-1025 for MAPEP Series 34 which is summarized in Table 8. .

10. Summary of Participation in the ERA MRaD PT Program

!

The ERA MRad progra.m provided samples (MRAD-24 and MRAD-25) for one hundred ninety four (194) individual environmental analyses. One hundred ninety three (193) of the 194 analyses fell within the PT provider's acceptance criteria (99.4% within acceptance). One analytical failure occurred: Total Uranium in water.

For the corrective actions associated with MRAD-24, refer to CARR160519-1015 which is summarized in Table 8. *

11. Summary of Participation in the ERA PT Program The ERA program provided samples (RAD-104, RAD-105, RAD-106, and QR030716U) for fifty one (51) individual environmental analyses. Of the 51 analyses, 92.1 % (47 out of 51) of all results fell within the PT provider's acceptance criteria.

CARR 160229-1005 documents the unacceptable result of Cs-137 and Gross Alphas from Study RAD-104, CARR 160830-1052 documents the unac;:ceptable result of Strontium-89 from Study RAD-106. All corrective actions are summarized in Table 8.

P.O. Box 30712, Charleston, SC 29417 2016 ANNUAL QUALIJY ASSURANCE REPORT Page 11 of60

12. Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002.

A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention, of the problem is required. Formal corrective action investigations include root cause analysis.

GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement. Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery:

Table 8 provides the status of CARRs for radiological performance testing during 2016. It has been determined that causes of the failures did not impact any data reported to our clients.

RAD 104 for Cesium-137 and Gross EPA 901.1,HASL 300 Ga-01, DOE 4.5.2.3 Alpha. After a review of the data, an apparent reason for this discrepancy could not be determined. The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 102%.

2. Laboratory control data were also reviewed for trends.

None were noted.

3. The instrument calibrations were reviewed for biases that could have attributed to this failure. Biases were not noted.

4. A sample duplicate was also prepared and counted along with the reported result. The ~esult fell within the method's acceptance range for duplicates.

5. A remedial sample from the QR030716U stucly was

'* performed for Cs-137.' The result fell well within the acceptance range for the study.

Gross Alpha EPA 00-02, EPA 900.0 and EPA 9310 After a review of the data, an apparent reason for this discrepancy could not be determined. The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 102%

(EPA 00-02) and 113% (EPA 900.0 and EPA 9310).

2. Laborat~ry control data were also reviewed for trends.

None were noted.

3. The instrument calibrations were reviewed for biases that could have attributed to this failure. Biases were not noted.

4. The batch quality control samples were reviewed and found to be compliant. The LCS Sample duplicates were also prepared and counted along with the reported results. The results for both fell

P.O. Box 30712, Charleston, SC 29417 2016 ANNUAL QUALITY ASSURANCE REPORT Page 58 of60 within the methods' acceptance ranges for duplicates.

5. The sample was re-analyzed in duplicate following EPA 00-02 and results (80 pCi/L and 82 pCi/L) that fell within the acceptance range were obtained.

Permanent Corrective/Preventive Actions or Improvements :

The laboratory must assume unidentified random error caused the elevated bias because all quality control criteria were met for the batch. Additionally, a well characterized performance evaluation sample from another vendor was prepped and analyzed a few weeks after this sample. The lab will continue to monitor~the recoveries of this parameters to ensure that there are no issues.

A second PT (RA0-103) was successfully analyzed for

'this matrix.

-MRAD-24 for Total Uranium in Water This failure was due to a data entry error. The Uranium-Total (mass) concentration in ug/L was inadvertently reported as the Uranium-Total in pCi/L.

The cause of this failure was determined to be human error.

The Uranium-Total (mass) result was inadvertently entered as r

the result for Uranium-Total (pCi/Kg). These results are hand entered into the PT provider's database.

Permanent Corrective/Preventive Actions or Improvements :

A parmname synonym was entered into Alpha Urns to distinguish Uranium-Total activity from Uranium-Total (mass) concentration. This change drastically reduced the potential for such errors to occur in the future

A second PT (MRA0-25) was successfully analyzed for this matrix.
