State CMDP Administrator roles are usually the main contact support for labs and water systems submissions/reporting of an individual state/region. The document, Shared CROMERR Services (SCS) Advanced Services Help Desk User Guide provides the description of SCS Admin Tool (State’s Helpdesk Tool -- section 3, page 9) available in each State CMDP Administrator account. This tool can help primacy agencies manage Sample submissions from Lab/WS users.
