Where can I get a list of data qualifier flags?
As noted above, ORCR considers data reporting to be a project-specific issue. Therefore, data reporting forms and qualifiers are not described in the SW-846 manual. If you have a data report from a laboratory that does not include the definitions of the qualifiers that they used, then you should contact that laboratory and request that information. Lists of qualifiers used in other EPA programs (e.g., CLP, NPDES) may be available from those programs, but they are not part of SW-846.
