To assure the quality of our data, all laboratories operated by EPA, including contractor operated facilities need to maintain a documented Quality System. At a minimum, the system must comply with the requirements of the EPA Quality System as defined by CIO 2105.0 May 2000, Policy and Program Requirements for the Mandatory Agency-wide Quality System. This policy is listed below and contains the specific requirements.
