Definitions and Interpretation of Statistical Analysis:

Assigned Value: Value attributed to a particular quantity and accepted, sometimes by convention, ashaving an uncertainty appropriate for a given purpose. See ISO/IEC 17043 for additional information. Ingeneral the assigned value is the value used to assess proficiency and may or may not be the made to value(gravimetric value).

Accept. Window: The range of values that constitute acceptable performance for a laboratory participatingin this PT study.

Z: A Z-Score tells how a single data point compares to normal data. A Z-Score says not only whether a pointwas above or below average, but how unusual the measurement is. Generally, a method result with aZ-Score less than |2| is considered to be in control, a Z-Score between |2| and |3| is considered’Questionable’, but still within control and a Z greater than |3| is considered not acceptable and the methodis out of control. For WS studies, a z-score greater than |2| is unacceptable. Calculated as Z = (ReportedValue - Assigned Value) / Proficiency Std. Dev.

Proficiency Std. Dev.: Standard deviation calculated based on Evaluation Criteria.

Study Mean: Statistical study mean calculated using a robust statisitical model (RTC employs the’Biweight Program’). Robust statistical techniques to minimize the influence that extreme results can haveon estimates of the mean and standard deviation. NOTE - These techniques assign less weight to extremeresults, rather than eliminate them from a data set.

Study Std. Dev.: Standard deviation calculated from study data using robust statisicals (Biweight).

Gravimetric Value: The ’prepared to’ value, determined by gravimetric means. The uncertainty associatedto this value is standard uncertainty and based on RTC’s gravimetric tolerances.

Evaluation Criteria:

1 - Regression Equation - Acceptance windows based on TNI adopted equation of proficiency value +/- 3proficiency standard deviations and check limits of proficiency value +/- 2 proficiency standard deviations.Proficiency value and proficiency standard deviation are calculated from gravimetric variables a, b, c, & das proficiency value = a * gravimetric + b and proficiency standard deviation = c * gravimetric + d.

2 - Study Robust Mean and c,d regression - Acceptance windows based on TNI adopted equation ofproficiency value +/- 3 proficiency standard deviations and check limits of proficiency value +/- 2proficiency standard deviations. Proficiency value and proficiency standard deviation calculated from robuststudy mean and variables c & d as proficiency value = robust mean and proficiency standard deviation = c *proficiency value + d.

3 - Fixed Limits - Acceptance windows based on span of gravimetric percentage from gravimetric asgravimetric +/- gravimetric * percentage.

4 - Adjustable Fixed Limits - Acceptance windows base on a span of gravimetric percentage fromgravimetric as gravimetric +/- gravimetric * lowPercentage where gravimetric < break and gravimetric +/-

LPTP17-S3


09-29-2017 49445626 LPTP17-S3 Page 20 of 22

gravimetric * highPercentage where gravimetric >= break.

5 - Study Statistics - Acceptance windows based on a number of standard deviations span from the studymean as study mean +/- (deviations * standard deviation).

6 - Log Transform Statistics - Acceptance windows based on lognormal distributed data. Acceptancewindows = mean(lognormal) +/- span * standard deviation(lognormal).

7 - Reserved

8 - Regression Equation 2SD - Acceptance windows based on EPA equation of proficiency value +/- 2proficiency standard deviations. Proficiency value and proficiency standard deviation are calculated fromgravimetric variables a, b, c, & d as proficiency value = a * gravimetric + b and proficiency standarddeviation = c * gravimetric + d. Generally reserved for drinking water studies.

Proficiency Test Item Preparation, Homogeneity and Stability Assessment - RTC uses proprietaryand published methods for the manufacture, homogeneity and stability testing of proficiency test items.RTC’s proficiency test materials meet requirements of ISO Guide 34. For more information contact RTC.Additionally RTC complies with TNI Volume 3 ’General Requirements for Environmental Proficiency TestProviders’, EL-V3-2009, 2009 for all TNI Fields of Proficiency Testing analytes.

Metrological Traceability - All preparations are made using balances calibrated annually traceable toNIST standards. Where appropriate analytical measurements are traceable through an unbroken chain toNIST standards, or a Certified Reference Material manufactured under ISO Guide 34 in conjunction withISO/IEC 17025.

Statistical Analysis - RTC uses robust statistics to calculate study means and standard deviations -Reference - Kafadar, K, A Biweight Approach to the One-Sample Problem, Journal of the AmericanStatistical Association, Vol. 77, No. 378, June, 1982, pp. 416-424.

Additional Information - Go to www.pt.sigmainformatics.com for additional information on summarystatistics for specific methods, advice on the interpretation of the statistical analysis, and additionalcomments/recommendations. If you failed an analyte it may be required to perform a corrective actionand/or retest. RTC recommends that you contact your accreditation body for specific instruction.

September 11, 2017

Donny JuarezEnergy LaboratoriesPO Box 247Casper, WY 82602

Enclosed is your final report for ERA's SOIL-99 Proficiency Testing (PT) study. Your final report includes an evaluation of all results submitted by your laboratory to ERA.

Data Evaluation Protocols: All analytes in ERA's SOIL-99 Proficiency Testing study have been evaluated using the following tiered approach. If the analyte is listed in the current TNI Fields of Proficiency Testing (FoPT) tables, the evaluation was completed by comparing the reported result to the acceptance limits generated using the criteria contained in the current TNI FoPT tables. If the analyte is not included in the TNI FoPT tables, the reported result has been evaluated using the procedures outlined in ERA's Standard Operating Procedure for the Generation of Performance Acceptance Limits (SOP 730002268).

Corrective Action Help: As part of your accreditation(s), you may be required to identify the root cause of any "Not Acceptable" results, implement the necessary corrective actions, and then satisfy your PT requirements by participating in a Supplemental (QuiK™Response) or future ERA PT study. ERA's technical staff is available to help your laboratory resolve any technical issues that may be impairing your PT performance and possibly affecting your routine data quality. Our laboratory and technical staff have many years of collective experience in performing the full range of environmental analyses. As part of our technical support, ERA offers QC samples that can be useful in helping you work through your technical issues.

At the request of the TNI Accreditation Council, we have included a Laboratory Exception Report that includes a list of all analytes reported with less than qualifiers when the assigned value was greater than “0.” In addition, because we have received many requests from laboratories, this report also includes a list of all analytes with "Not Acceptable" evaluations.

Some states have elected not to convert to the 2009 TNI Standards at this time. If you have released your results to a state that has retained the 2003 NELAC Evaluation Criteria, your final report will include a section that evaluates the results according to the 2003 Standard in addition to the 2009 TNI Standards.

Thank you for your participation in ERA's SOIL-99 Proficiency Testing study. If you have any questions, please contact our Proficiency Testing Department at 1-800-372-0122.

Sincerely,

Patrick LarsonQuality Officer

All analytical verification data for all analytes in the standards met the acceptance criteria contained in the 2009 TNI PT Standard and the criteria contained in the most current TNI FoPT tables.

The data submitted by participating laboratories was also examined for study anomalies. There were no anomalies observed during the statistical review of the data.

ERA's SOIL-99 Proficiency Testing study reports shall not be reproduced except in its entirety and not without the permission of the participating laboratory. The report must not be used by the participating laboratories to claim product endorsement any agency of the U. S. government.

The Reported Value is the value that the laboratory reported to ERA.

The ERA Assigned Values for the Organic Proficiency Testing Standards, with the exception of Acetonitrile in the Volatiles in Soil sample, are equal to 100% of the parameter present in the standard as determined by gravimetric and/or volumetric measurements made during standard preparation as applicable. The ERA assigned value for Acetonitrile is equal to the mean of the study data, after the removal of outliers. The ERA assigned values for the Inorganic Proficiency Testing Standards, with the exception of the TCLP Metals in Soil and Total Organic Carbon (TOC) in the Nutrients in Soil sample, are equal to the maximum amount of the parameter available in the standard by applicable EPA methodologies. The ERA assigned values for the TCLP metals and TOC are equal to the mean of the study data, after the removal of outliers. All parameters not added to the standard are given an Assigned Value of "< PTRL", per the guidelines contained in the 2009 TNI Standards. The assigned values are directly traceable to the commercially prepared starting materials used to manufacture the PT standards.

The Acceptance Limits are established per the criteria contained in the most current TNI Fields of Proficiency Testing (FoPT) tables, or ERA's SOP for the Generation of Performance Acceptance Limits™ as applicable.

Definitions and Interpretation of Statistical Analysis:

Assigned Value: Value attributed to a particular quantity and accepted, sometimes by convention, ashaving an uncertainty appropriate for a given purpose. See ISO/IEC 17043 for additional information. Ingeneral the assigned value is the value used to assess proficiency and may or may not be the made to value(gravimetric value).

Accept. Window: The range of values that constitute acceptable performance for a laboratory participatingin this PT study.

Z: A Z-Score tells how a single data point compares to normal data. A Z-Score says not only whether a pointwas above or below average, but how unusual the measurement is. Generally, a method result with aZ-Score less than |2| is considered to be in control, a Z-Score between |2| and |3| is considered’Questionable’, but still within control and a Z greater than |3| is considered not acceptable and the methodis out of control. For WS studies, a z-score greater than |2| is unacceptable. Calculated as Z = (ReportedValue - Assigned Value) / Proficiency Std. Dev.

Proficiency Std. Dev.: Standard deviation calculated based on Evaluation Criteria.

Study Mean: Statistical study mean calculated using a robust statisitical model (RTC employs the’Biweight Program’). Robust statistical techniques to minimize the influence that extreme results can haveon estimates of the mean and standard deviation. NOTE - These techniques assign less weight to extremeresults, rather than eliminate them from a data set.

Study Std. Dev.: Standard deviation calculated from study data using robust statisicals (Biweight).

Gravimetric Value: The ’prepared to’ value, determined by gravimetric means. The uncertainty associatedto this value is standard uncertainty and based on RTC’s gravimetric tolerances.

Evaluation Criteria:

1 - Regression Equation - Acceptance windows based on TNI adopted equation of proficiency value +/- 3proficiency standard deviations and check limits of proficiency value +/- 2 proficiency standard deviations.Proficiency value and proficiency standard deviation are calculated from gravimetric variables a, b, c, & das proficiency value = a * gravimetric + b and proficiency standard deviation = c * gravimetric + d.

2 - Study Robust Mean and c,d regression - Acceptance windows based on TNI adopted equation ofproficiency value +/- 3 proficiency standard deviations and check limits of proficiency value +/- 2proficiency standard deviations. Proficiency value and proficiency standard deviation calculated from robuststudy mean and variables c & d as proficiency value = robust mean and proficiency standard deviation = c *proficiency value + d.

3 - Fixed Limits - Acceptance windows based on span of gravimetric percentage from gravimetric asgravimetric +/- gravimetric * percentage.

4 - Adjustable Fixed Limits - Acceptance windows base on a span of gravimetric percentage fromgravimetric as gravimetric +/- gravimetric * lowPercentage where gravimetric < break and gravimetric +/-

QT-0007375


10-12-2017 49445626 QT-0007375 Page 29 of 31

gravimetric * highPercentage where gravimetric >= break.

5 - Study Statistics - Acceptance windows based on a number of standard deviations span from the studymean as study mean +/- (deviations * standard deviation).

6 - Log Transform Statistics - Acceptance windows based on lognormal distributed data. Acceptancewindows = mean(lognormal) +/- span * standard deviation(lognormal).

7 - Reserved

8 - Regression Equation 2SD - Acceptance windows based on EPA equation of proficiency value +/- 2proficiency standard deviations. Proficiency value and proficiency standard deviation are calculated fromgravimetric variables a, b, c, & d as proficiency value = a * gravimetric + b and proficiency standarddeviation = c * gravimetric + d. Generally reserved for drinking water studies.

Proficiency Test Item Preparation, Homogeneity and Stability Assessment - RTC uses proprietaryand published methods for the manufacture, homogeneity and stability testing of proficiency test items.RTC’s proficiency test materials meet requirements of ISO Guide 34. For more information contact RTC.Additionally RTC complies with TNI Volume 3 ’General Requirements for Environmental Proficiency TestProviders’, EL-V3-2009, 2009 for all TNI Fields of Proficiency Testing analytes.

Metrological Traceability - All preparations are made using balances calibrated annually traceable toNIST standards. Where appropriate analytical measurements are traceable through an unbroken chain toNIST standards, or a Certified Reference Material manufactured under ISO Guide 34 in conjunction withISO/IEC 17025.

Statistical Analysis - RTC uses robust statistics to calculate study means and standard deviations -Reference - Kafadar, K, A Biweight Approach to the One-Sample Problem, Journal of the AmericanStatistical Association, Vol. 77, No. 378, June, 1982, pp. 416-424.

Additional Information - Go to www.pt.sigmainformatics.com for additional information on summarystatistics for specific methods, advice on the interpretation of the statistical analysis, and additionalcomments/recommendations. If you failed an analyte it may be required to perform a corrective actionand/or retest. RTC recommends that you contact your accreditation body for specific instruction.

Donny JuarezEnergy LaboratoriesPO Box 247Casper, WY 82602

Enclosed is your final report for ERA's SOIL-100 Proficiency Testing (PT) study. Your final report includes an evaluation of all results submitted by your laboratory to ERA.

Data Evaluation Protocols: All analytes in ERA's SOIL-100 Proficiency Testing study have been evaluated using the following tiered approach. If the analyte is listed in the current TNI Fields of Proficiency Testing (FoPT) tables, the evaluation was completed by comparing the reported result to the acceptance limits generated using the criteria contained in the current TNI FoPT tables. If the analyte is not included in the TNI FoPT tables, the reported result has been evaluated using the procedures outlined in ERA's Standard Operating Procedure for the Generation of Performance Acceptance Limits (SOP 730002268).

Corrective Action Help: As part of your accreditation(s), you may be required to identify the root cause of any "Not Acceptable" results, implement the necessary corrective actions, and then satisfy your PT requirements by participating in a Supplemental (QuiK™Response) or future ERA PT study. ERA's technical staff is available to help your laboratory resolve any technical issues that may be impairing your PT performance and possibly affecting your routine data quality. Our laboratory and technical staff have many years of collective experience in performing the full range of environmental analyses. As part of our technical support, ERA offers QC samples that can be useful in helping you work through your technical issues.

At the request of the TNI Accreditation Council, we have included a Laboratory Exception Report that includes a list of all analytes reported with less than qualifiers when the assigned value was greater than “0.” In addition, because we have received many requests from laboratories, this report also includes a list of all analytes with "Not Acceptable" evaluations.

Some states have elected not to convert to the 2009 TNI Standards at this time. If you have released your results to a state that has retained the 2003 NELAC Evaluation Criteria, your final report will include a section that evaluates the results according to the 2003 Standard in addition to the 2009 TNI Standards.

Thank you for your participation in ERA's SOIL-100 Proficiency Testing study. If you have any questions, please contact our Proficiency Testing Department at 1-800-372-0122.

Sincerely,

David KilhefnerQuality Officer
