Ensuring Measurement Competency

EPA established policies to better ensure the quality of information from data generated, collected and used for making scientific and regulatory decisions. 

On this page:
  • Internal Measurement Competency
  • Measurement Competency Under Acquisition Agreements
  • Measurement Competency Under Assistance Agreements
 

Internal Measurement Competency

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 Environmental Information Quality Policy.

Internal Measurement Competency Documents


Measurement Competency Under Acquisition Agreements

On March 28, 2011, an EPA policy was issued for all organizations performing environmental analysis to demonstrate their qualifications in the field(s) of analyses to be conducted, prior to performing such analyses, under Agency-funded acquisitions. This requirement is another part of the Agency's continued effort to ensure the quality and validity of environmental measurement data.
