ABSTRACT
The TNI National Laboratory Accreditation Database is used to track environmental laboratory accreditation by matrix, method, and analyte. In order to eliminate confusion and work efficiently in a database structure, methods are assigned method codes that include the specific method reference, revision, and revision date. Methods approved by EPA for compliance reporting under Drinking Water and Wastewater were identified. The process of method reconciliation exposed a number of conflicts and sources of confusion between the references in the CFR, on the web, and in the method source documents. This paper documents those challenges and offers a potential solution.
