Performance Evaluation Program

As part of ASU's accreditation requirements the lab routinely participates in proficiency testing studies from various accredited providers including CALA.

The principals and methodology applied to CALA accredited methods are applied to all analysis performed in our laboratories. Rigorous quality control procedures are employed. The use of certified laboratory control standards (LCS), analysis of preparation duplicates and blanks, repeat recalibration and use of separate source calibration check standards ensures that the data we provide is of the highest quality and is completely reproducible.

The ASU's CALA accreditation document is shown below:


CALA Accreditation



CALA is an organisation dedicated to achieving the highest possible levels of quality data within Canadian environmental laboratories. Laboratories which are CALA accredited go through regular confirmatory testing. The methods relevant to individual labs, their locations, and their performance evaluations are listed in the CALA homepage.

The ASU has been an accredited laboratory since 1995.
