NWDTW 2024

Groundwater Site Inventory (GWSI) version 5.2 is a menu-based data storage and management system on the UNIX platform that is nearing end-of-life and requires modernization. GWSI includes site inventory information and groundwater thematic metadata and is considered part of legacy National Water Information System (NWIS). GWSI is currently in the process of being replaced by modern solutions as part of the NWIS Modernization Program, and the legacy product will be retired by the end of Fiscal Year 2025. By that time, all data stored within legacy GWSI will either be deprecated and archived or migrated to one of three locations: Monitoring Location Registry (MLR), AQUARIUS Time-Series (AQTS), or the new GroundWater Information System (GWIS) database, pronounced as “GeeWhiz”. In this presentation, we will outline the plan for completing modernization, provide updates on our progress so far, and discuss requests for help from Water Science Center Local Data Managers (LDMs) on several cleanup tasks associated with archival and migration.
