WQX Web Account Registration

How to Gain Access to WQX Web

Access to WQX web occurs through EPA’s portal for environmental data, the Central Data Exchange (CDX). This process involves registration of two accounts: one with CDX to verify your identity and allow you access to the WQX web application and one with the WQX team that will allow you to submit data to EPA for your specific organization. After registration of these two accounts, the process of accessing WQX web through CDX is seamless and only requires one login step. The WQX team will help guide you through registration and field any questions you may have along the way.

Does my Organization have an ID registered with WQX?

All Organizations submitting data through WQX Web require a WQX Organization ID that is unique from any previous STORET Org IDs. Using the appropriate Organization ID is incredibly important in order to maintain consistency and decrease the chance of data duplication or deletion. If you are unsure if your organization has a WQX ID, the best way to find out is to search the Water Quality Portal under the ‘Organization ID’ field. See this video tutorial all about how to search for this information: Coming Soon. If you are still unsure if your organization has a registered ID, ask the WQX team to assist you.  

If you need to set up a WQX Organization ID, please contact the WQX help desk by email ( We will ask that you provide us with the following information in order to set up the Organization ID:

  • WQX Organization ID of your choice (can be up to 30 characters long)
  • WQX Organization Name
  • Your contact information as outlined above

2. WQX team email response

After you have sent a request to the WQX team for a WQX Web account and a WQX Organization ID, you will receive an email from the team confirming your request. We will notify CDX of your intent to register and authorize your access to WQX web. 

3. CDX will email you with registration instructions

After we notify CDX they will send you an email with instructions on how to register an account with them.  This is a separate account from your WQX web account and is used to verify your identity. This message will include information about your user name and how to access the Customer Retrieval Key (CRK) that is mandatory for registering in CDX. All user names for CDX must follow the convention: firstnamelastname (example "michaeljones"). Once you have used your CRK to register, you will be able to set up your CDX user account and gain access to the WQX Web application.

4. Log into CDX and confirm access to WQX Web
