A. Documentation of Corrective Actions.
(1) If a certified water quality laboratory is found to be in noncompliance with these regulations, the water quality laboratory shall submit documentation of corrective action to the Department.
(2) If a certified water quality laboratory is found to be in noncompliance with an on-site evaluation by another state or third-party organization, the laboratory shall forward copies of the associated on-site evaluation report or reports, the laboratory’s follow up corrective actions, and notifications of certification status.
B. Adequacy of Corrective Action. On receipt of documentation of corrective action, the Certification Authority shall determine the adequacy of the action taken. If the corrective action is not adequate, the water quality laboratory may be required to test supplemental proficiency test samples or submit to an on-site inspection, or both. If the results of the on-site inspection or the results obtained through testing of unknown samples are unacceptable, the water quality laboratory shall be downgraded for the specific tests for which results are unacceptable or procedures, facilities, or records are not in compliance.
C. Continued Certification of Other Tests. The certified water quality laboratory shall continue to be certified for performance of all tests for which it has demonstrated satisfactory performance through testing of unknown samples and through compliance with these regulations.
D. Notification About Discrepancies. The Department shall advise owners and water quality laboratory supervisors in writing of all certified water quality laboratory discrepancies which may lead to revocation of certification, or a downgrade to provisional status.
