ERA's WP-240 WatR�Pollution Proficiency Testing study has been reviewed by ERA senior management and certified compliant with the requirements of the 2009 TNI PT Standard and the criteria contained in the most current TNI Fields of Proficiency Testing (FoPT) tables.

ERA's WP-240 WatR�Pollution study standards were examined for any anomalies. A full review of all homogeneity, stability and accuracy verification data was completed. All analytical verification data for all analytes 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 WP-240 WatR�Pollution study reports shall not be reproduced except in their entirety and not without the permission of the participating laboratories. The report must not be used by the participating laboratories to claim product endorsement by any agency of the U. S. government.

The data contained herein are confidential and intended for your use only.

If you have any questions or concerns regarding your assessment in ERA's WatR�Pollution Proficiency Testing program, please contact our Proficiency Testing Department at 1-800-372-0122.

The Method Description is the method the laboratory reported to ERA.

=

=

=

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

The ERA Assigned Values are compliant with the most current TNI Fields of Proficiency Testing (FoPT) tables. A parameter not added to the standard is given an Assigned Value of "< PTRL" per the guidelines contained in the 2009TNI 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 USEPA/NELAC FoPT tables, or ERA's SOP for the Generation of Performance Acceptance Limits� as applicable.

Not Reported No Value reported.=

Dear Josh,

Thank you for participating in the WPM0115 Water Pollution Proficiency Testing Study.

Enclosed is your final report, which has been carefully reviewed by the PT specialists at

Phenova. This report presents some additional sections and features which will give you

more information on the study data for the standards that were reported by your laboratory

and more information regarding the overall performance of your laboratory in relation to

other study participants.

The enclosed report is in two sections, the "Evaluation Report" and the "Statistical Report".

The "Evaluation Report" contains the evaluation of your reported data as well the reported

method, analysis date and analyst. The "Evaluation Report" is an updated and enhanced

version of the reports you previously received at the conclusion of our PT studies. The

"Statistical Report" contains your passing percentage as well as statistics from the study

for the analytes reported by your laboratory.

For any analyte falling outside the established acceptance limits, our PT management staff

would like to assist you in determining the most appropriate course of corrective action for

your facility. Please contact us at any time if we may be of service to you.

Thank you again for participating in the WPM0115 Water Pollution Proficiency Testing

Study. We appreciate working with you and look forward to our next study. If you have any

questions, please call us at 866-942-2978.

The Assigned Value is determined from the study mean, gravimetric

and volumetric true concentration of an analyte to be analyzed,

calculation and/or an appropriate reference value as stipulated in the

EPA National Standards for Water Proficiency Testing Studies Criteria

Document (current version), the National Environmental Laboratory

Accreditation Conference (NELAC) criteria (ref: NELAC FOT tables,

NELAC PT Committee) and other documents distributed by accrediting

agencies as applicable.

Assigned Value

Evaluation Limits Acceptance Limits are derived from fixed limits, coefficients, constants

and calculations stipulated in the EPA National Standards for Water

Proficiency Testing Studies Criteria Documents (current version), the

National Environmental Laboratory Accreditation Conference (NELAC)

criteria (ref: NELAC PT FOT tables, NELAC PT Committee) and other

documents distributed by accrediting agencies as applicable.

Evaluation

Acceptable The reported value falls within the Acceptance Limits.

No Evaluation

NR

The reported value is non-numeric and can not be evaluated.

As required by the NELAC standards and requested by state

authorities, any analyte purchased but not reported by your facility is

listed as NR (Not Reported).

Not Acceptable The reported value falls outside the Acceptance Limits.

Study Mean and

Standard Deviation

The mean and standard deviation are calculated from the study data

using robust statistical calculations when possible. Other statistical

calculations may be used if robust statistical calculations are not

possible. The displayed values are independent of any statistical

calculations required for the calculation of the analyte evaluation

limits.

This report must not be reproduced except in full, without the written approval of Phenova.

This report must not be used to claim product certification, approval, or endorsement by the American Association for Laboratory

Accreditation (A2LA) or any agency of the federal government.
