Summary
This layer was developed in order to spatially reference the watersheds that supply drinking water to surface water intakes for Public Water Systems (PWS) within the state of Oregon. Source water assessments were completed for these PWS's in accordance with the 1996 Amendments to the Safe Drinking Water Act and Oregon's 1999 Source Water Assessment Plan. The original list of PWSs was generated in 1999, however additional PWSs may be added in the future. These source areas should be used in conjunction with the locations of potential contaminant source threats as well as mapped sensitive areas to provide an overall picture of the susceptibility of the drinking water system.
Description
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.
Credits
All original surface water source area files and combined GIS spatial data files were developed or established by the Oregon Department of Environmental Quality, Water Quality Division/Drinking Water Protection Program.
Access and use limitations
This product is for informational purposes and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. Users of this information should review or consult the primary data and information sources to ascertain the usability of the information. This information or data is provided with the understanding that conclusions drawn from such information are the responsibility of the user. Surface water source areas were delineated intake to intake. For watersheds with more than one intake, Oregon reported source water assessments results by watershed segment representing the area from the public water system's intake to the next intake upstream.

Access constraints: Drinking water source area data was prepared using public funds and is available for public use. The original list of public water systems (PWS) was generated in 1999, however additional PWSs and their associated drinking water source areas (DWSA) may be added in the future. For security purposes, the locational coordinates for surface water intakes are provided only to government agencies. The well, spring, and intake locations may not be transmitted or redistributed without prior authorization from Oregon Dept. of Human Services or Oregon Dept. of Environmental Quality; do not publish or redistribute the intake coordinates.
This GIS layer is a graphic representation of Public Water System (PWS) surface water drinking water source areas (DWSAs) associated with intakes identified under the Oregon Dept. of Environmental Quality & Oregon Dept. of Human Services (DHS), "Source Water Assessment Plan" in 1999. The original list of public water systems (PWS) was generated in 1999, however additional PWSs and their associated DWSAs will be added in the future. PWSs whose status changed to community or non-transient non-community since the 1999 list was generated may not be included; PWSs that have become inactive may be deleted. Additional PWS DWSAs are included but may be removed before general public release of the data. Where the identified PWSs DWSA map from DEQ and the GIS layer differ, the DEQ map based on hydrogeologic methods takes precedence. The maps included as figures in assessment reports to individual PWSs are the map of record. Users are advised that this layer is designed to be used in conjunction with the surface water intake layer. There may be both revisions and corrections to the GIS representation without notice. Care was taken in the development of these GIS layers, but they are made available "as is". There are no warranties, express or implied, including the warranty of fitness for a particular purpose, accompanying these layers. Notification of any discrepancies between the GIS representation and the GPS-based location data will be appreciated.

All source areas upstream of a specific water system's intake are included in the drinking water source area (DWSA) for that water system and PWSs are encouraged to work with other water providers and other entities within the subbasin as they move forward with developing protection strategies. Oregon's obligation was to conduct the Source Water Assessments for the watershed area upstream of the intake to the state border. In cases where the source area extends beyond the state border or the PWS's jurisdiction, coordination with adjacent states or other jurisdictions should be considered prior to protection planning.

This data is for community (C) and non-transient non-community (NTNC) public water systems (PWS) only. Data was compiled in cooperative effort between Oregon Dept. of Environmental Quality/Water Quality Division, Drinking Water Protection Program and Oregon Dept. of Human Resources/Drinking Water Program. A community PWS regularly serves at least 25 year-round residents or serves at least 15 service connections used by year-round residents. A non-transient non-community PWS is not a community PWS and regularly serves at least 25 of the same people over 6 months per year (for example, work sites and schools). Source Water Assessment results for 1,100 public water systems serving approximately 2,360,000 Oregonians are included in this data set. Oregon’s Source Water Assessment methods and more information on Oregon’s Drinking Water Protection Program are provided at http://www.deq.state.or.us/wq/dwp/dwphome.htm. Source Water Assessment results for transient non-community systems (NC) (a PWS that does not regularly serve at least 25 of the same people over 6 months per year (i.e. rest areas, campgrounds) )are not included in this data. Information on private water supplies was not collected as part of the Source Water Assessment project. For surface water, the drinking water source area (DWSA) is defined as the geographic area (watershed) that supplies the water body where the intake is located. Surface water source areas were delineated intake to intake. For watersheds with more than one intake, Oregon reported source water assessments results by watershed segment representing the area from the public water system's intake to the next intake upstream. All source areas upstream of a specific water system's intake are included in the drinking water source area for that water system and PWSs are encouraged to work with other water providers and other entities within the subbasin as they move forward with developing protection strategies. Oregon's obligation was to conduct the Source Water Assessments for PWSs within the state border. In cases where the source area extends beyond the state border or the PWS's jurisdiction, coordination with adjacent states or other jurisdictions should be considered prior to protection planning.
