Description:
These polygons were developed in order to spatially reference source areas that supply drinking water to groundwater wells or springs for Public Water Systems (PWSs) 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, and the 2015-2019 Updated Source Water Asessments. The original list of PWSs was generated in 1999, however additional PWSs 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 or may be added as updates are performed; PWSs that have become inactive may be deleted. These source areas are to 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.

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), and then re-asssessed between 2015-2019. Data is updated and modified as needed.

This product is for informational purposes and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. This data set is not designed for use as a primary regulatory tool in permitting or siting decisions, but may be used as a reference source. No warranty expressed or implied is made regarding the accuracy of the data. Users of this information should review or consult the primary data and information sources to ascertain the usability of the information. It is recommended that careful attention be paid to the contents of the metadata file associated with these data. 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. The original list of public water systems (PWS) was generated in 1999 and then updated btween 2015 and 2019, However, additional PWSs and their associated drinking water source areas (DWSA) may be added in the future.
