STORET/WQX: Monthly Domain Value Alerts

Monthly Domain Value Alerts

The EPA STORET Team hosts conference calls about once a month to allow STORET/ WQX users to hear about developments with the STORET/ WQX System and express their comments/questions directly to the STORET staff. WQX Domain Value Alert Archives are posted below.


EPA makes available domains of WQX data elements for both submission and retrievals. Domains are publicly accessible to assist others in conforming to a consistent nomenclature. A "domain-values" web service can be queried to determine the EPA-supplied values of the domains used for both submission and retrievals. These domain value web services directly access the WQX Domain Tables.

1. The Characteristic domain values provide information on substances as defined by the USEPA Substance Registry System (SRS) Note, there are a small number of exceptions which are recognized by the USEPA WQX system.
To Request a new Characteristic provide the following as applicable:
Name, EPA SRS Number (n/a), CAS Number (n/a), Documentation/URL, if no SRS/CAS Number.

2. The Taxon domain values are biological names primarily stewarded by the Integrated Taxonomic Information System (ITIS) and the ITIS Catalogue of Life. Taxonomic names from academic journals or accredited sources may also be added if reference information is provided (i.e. a URL or citation). Click here to view updated taxon names as of 09/25/2013.
