Name: Groundwater 2-yr TOT (Zone 1 for Springs)

Display Field: PWS_Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer includes Oregon Department of Environmental Quality (DEQ) and Oregon Health Authority (OHA) Drinking Water Program Source Water Assessment drinking water source area results for community (C), non-transient non-community (NTNC), transient non-community (TNC), and some state-regulated (SP) public water systems (PWS) for groundwater public water systems that were active in June 1999 (when Oregon's Source Water Assessment Plan was approved by EPA). Data is updated and modified as needed.

Copyright Text: Most original groundwater well, infiltration gallery, and spring drinking water source areas were established by the Oregon Health Authority ((OHA); formerly OR Dept. of Human Service), Drinking Water Program-Springfield Office under the direction of the Drinking Water Protection Groundwater Coordinator. Data includes "community", "nontransient noncommunity", and "transient noncommunity" public water supply sources. Limited "state-regulated" sources are also included. The combined GIS spatial data file of all wells, infiltration galleries, and springs was developed by Oregon Dept. of Environmental Quality/Water Quality Division/Drinking Water Protection.
