There are three principal ways that the SRS promotes data quality.
SRS Web services can be incorporated into online reporting forms managed by EPA, state, and tribal programs to help submitters identify the correct substance and to report that substance without having to type the name of the substance, thus reducing data entry errors.
The Substance Registry System (SRS), in its role supporting the Chemical Identification Data Standard and Biological Taxonomy Data Standard, provides standardized identifiers for each substance. These key fields uniquely identify each substance within SRS. When an EPA program, state or tribal partner uses these fields, they are relying on standardized, accurate, and unambiguous identification information for that substance.
There are many substances that have been reported under completely disparate names, where the only way to map these names to a standardized identification is through careful review and consultation by a workgroup of chemists and program analysts. The SRS provides the results of this standardization.
The SRS can rate the quality of a substance synonym. Identifying a substance name as inaccurate, misspelled, or ambiguous can prevent EPA program offices, states, tribes or other users from utilizing that synonym.
