STORET/WQX: WQX Domain Value Service
WQX Domain Value Services and Downloads
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.
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 04/01/2013.
3. The Analytical Procedures domain values are confined by the both USEPA and
the National Environmental Methods Index (NEMI),
with a small number of exceptions also implemented by the USEPA WQX system.
