Water-board staff explain CEDEN submission paths, vocabulary updates and timeline for CEDEN 2

At a CEDEN user group meeting (date not specified), State Water Board staff reviewed how monitoring data are currently submitted to the California Environmental Data Exchange Network (CEDEN), described recent vocabulary and method-business-rule updates for PFAS and PCR, and outlined the rollout plan and technical constraints for the CEDEN 2 replacement system.

The update matters because monitoring data flow into CEDEN in several different ways today, and some submission paths are temporarily routed to other regional data centers or to the open data portal. That routing affects where users can find newly submitted records, how they should format submissions, and what metadata (for example, project codes and method names) must conform to new character limits imposed by the CEDEN 2 schema.

State Water Board staff member Tessa said the best single contact for questions about submissions is the CEDEN inbox (ceden@waterboards.ca.gov) and asked users to contact that address for assistance. She explained that several regional data centers (RDCs) — including the Moss Landing Marine Laboratories regional data center, the San Francisco Bay Area RDC managed by the San Francisco Estuary Institute (SFEI), the Central Valley RDC managed by MLJ Environmental, and the SWAMP (Surface Water Ambient Monitoring Program) RDC — all feed into the statewide network that users access through the CEDEN query tool or related data marts.

Tessa described two common submission paths. If data are loaded by an RDC, those records go into the larger data marts and are discoverable through the CEDEN query tool. If users submit via the CEDEN…
