    Surface Water Drinking Water Source Areas

    Metadata Updated: October 4, 2025

    This data layer is an element of the Oregon GIS Framework. This map includes Oregon Department of Environmental Quality (DEQ) and Oregon Department of Human Services’ (DHS) Drinking Water Program Source Water Assessment results for community and non-transient non-community public water systems (PWS) for surface water systems that were active in June 1999 (when Oregon's Source Water Assessment Plan was approved by EPA). Subsequently, post-1999 systems have been added including some non-community systems.
