AQS Memos - Lead monitors and the analyzing agency

Lead Monitors and Analyzing Agency

For lead monitors in AQS, the “analyzing” agency should be the laboratory performing the lead filter analyses. (If the lab you use does not have an agency code in AQS, please contact AQSTeam@epa.gov)

In reviewing the lead monitors, we’ve found some that are missing the analyzing agency, or some for which the analyzing agency is set to the same agency as the PQAO. If this applies to one of your lead monitors, you will be receiving a separate email.
