Report Issued: 10/19/04 Study Dates: 06/03/04 - 09/03/04 DMRQA Study Discussion:

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

The ERA Assigned Values were established per the USEPA's guidelines contained In the National Standards for Water Proficiency Testing Studies Criteria Document, December 1998.

The Acceptance Limits and Warning Umits are established per the USEPA's guidelines contained In the National Standards for Water Proficiency Testing Studies Criteria Document, December 1998.

The Performance Evaluation:

Acceptable

= Reported Value falls within the Acceptance Limits.

Not Acceptable = Reported Value falls outside the Acceptance Limits.

Check for Error = Reported Value falls within the Acceptance Limits and outside of the Warning Limits No Evaluation = Reported Value cannot be evaluated The Method Description Is the method the laboratory reported to ERA.

ERA's DMR-QA 24 Study has been reviewed by ERA Senior Management and certified compliant with the requirements of the USEPA's National Standards for Water Proficiency Testing Studies Criteria Document (December 1998). ERA Is a NIST NVLAP accredited PT Provider (Lab Code 200386-0).
