WAC: Water quality standards for groundwater in the State of Washington
This website presents the state regulations for groundwater quality.
Specific water quality criteria for groundwater are presented in
State of
Washington Groundwater Quality Criteria.
- Washington State Department of Health Drinking Water Program
Many of the public water supply systems in the state derive their water from groundwater wells. Visit this page to learn more about the state’s programs that oversee water quality from these systems. Don’t forget to also visit the
Drinking Water Program Data page for access to source information about these wells.

- State of Washington Water Research Center (SWWRC) Groundwater Report List
Based in Pullman, WA, the SWWRC assembles research on a wide variety of water resource topics, including groundwater issues. Search the Center's online publication list for groundwater or hydrogeochemistry reports in PDF format.
The SWWRC has also held several conferences focused on water resources in the
Northwest - see conference proceedings for
Groundwater Under the Pacific Northwest - Integrating Research, Policy, and Education, Stevenson, WA, Nov. 2-3, 2005,
and Water in the
Pacific Northwest - Moving Science into Policy and Action, Stevenson, WA,
November 7-8, 2007.

Department of Licensing Geologist/Hydrogeologist Licensing Program
Since 2001, most people conducting groundwater work in Washington State must
hold a valid state license as a hydrogeologist
or engineer, or work for someone who holds such a license (certain exemptions
apply). Visit the link above to learn more about the state licensing
program requirements and exemptions.
- Impacts of Climate Change on Groundwater Resources:
A Literature Review
This 2007 report was prepared by a University of Washington Climate Impact Group
technical committee, with a focus on evaluating potential changes on groundwater
conditions in the Puget Sound area that may result from a changing climate. Back to top
