Between 1999 and 2005, each public water system in Oregon received a source water assessment report completed by the Oregon Department of Environmental Quality and Oregon Health Authority drinking water programs. The assessment gives the water system and community information on the watershed or recharge area that supplies the well, spring or intake (the “drinking water source area”) and identifies potential risks within the source area.
In 2016 and 2017, the agencies are completing Updated Source Water Assessments to provide the water systems and communities more detailed information on the watershed or recharge area that supplies their well, spring or intake. DEQ opened public comment on the content and format of an USWA prototype on May 18, 2016. This public comment period allowed partner state agencies, stakeholders, and public water providers an opportunity to help make the information more useful and relevant. Comments received were used to improve the document. The prototype was finalized in August 2016.
Updated Source Water Assessments will be provided to all public water systems using surface water and are posted at the link below as they are completed. For groundwater systems, OHA has prioritized new Community and Non-Transient Non-Community water systems and systems that have added a new water source since their original source water assessment was completed. For groundwater system reports, contact Drue Edney, OHA, at 541-726-2587 ext. 25.
