AQS Web Home

Welcome to the Environmental Protection Agency (EPA) Air Quality System (AQS).  AQS has been migrated and deployed on the Web to eliminate the installation and updates of the AQS software on users' machines and to eliminate the need for the SecuRemote software.

First Time Users: There is a one-time initial setup needed to access the AQS Web application. Click the following link for AQS Initial Setup.   You may also find this AQS Web User Guide helpful. 

The Computer based training module for the AQS Web is designed for new as well as experienced users.  It allows users to work with the real system while going through the tutorials.  (This module is similar to the one for the client/server version of AQS.)
Save the Quick Ref Guide for AQS Web  for use once you're familiar with the system.

Use the following Links to Access AQS or CDX application directly. You can also access CDX while you are in AQS. NOTE: At this stage, access using each application directly will require you to login each time.

If you need assistance accessing any of the material in AQS, User Support is provided through the EPA Call Center. The toll free number is 866-411-4EPA (866-411-4372).  Please contact them first with any questions about using the AQS application.
