REGISTER of QUALITY APPROVED LABORATORIES SUBMITTING DATA to EPA 2020 Data

This register has been compiled in compliance with Section 66 of the EPA Act 1992.

Explanatory Note: Section 66 of the Environmental Protection Agency Act 1992 provides for the establishment of an intercalibration programme for the purpose of assessing analytical performance and ensuring the validity and comparability of environmental data for laboratories which submit data to the Agency. It also provides for the establishment of a register of quality approved laboratories which would normally be expected to send data to the Agency. This register lists, on a parameter by parameter basis, the laboratories which performed satisfactorily in the EPA intercalibration programme for the previous year. The register is updated annually. The objective criteria for inclusion in the register are listed below.

Criteria for compliance: 4 satisfactory returns from 5 or 3 satisfactory returns in consecutive rounds or current laboratory accreditation. Criteria for pH require 3 returns within 0.20 pH units of reference concentration and 1 return within 0.30 units.

Note to above: Only laboratories which provide data to the Agency, either directly or indirectly, are eligible to participate in the intercalibration programme. Some laboratories do not routinely carry out all of the tests listed on the register or may not have returned sufficient intercalibration data during 2020 to allow an assessment based on the above criteria for a particular parameter. It should not be inferred therefore, that the absence of a laboratory from the listing under a particular parameter necessarily implies unsatisfactory performance for that parameter. The parameters along with the laboratories which are deemed to have complied according to the above criteria are set out in the attached schedule.
