Description The Washington State Department of Ecology (Ecology) Water Quality Program undertook the Nitrate Prioritization Project in 2014 (Morgan, 2014) because of growing concerns about groundwater contamination by nitrates, and the inability to display and evaluate nitrate data on a statewide basis. The goals of this project were to:

  • Collect and organize statewide information about nitrate monitoring results.

  • Delineate areas where high nitrates in groundwater occur.

  • Prioritize those areas by potential impacts to people and resources.

  • Make this information available.


Boundaries for candidate Nitrate Priority Areas were developed. Once the proposed Nitrate Priority Areas have been reviewed, section line-based boundaries may be replaced by natural boundaries where appropriate.

Recommendations include developing a web application to make this information easily accessible by anyone with internet access, and automating the data downloads so they are easily updated.

Results of this study can be used to protect public drinking water supplies by focusing actions on areas within the state that have the highest potential for impacts due to nitrate contamination of groundwater.
REQUEST A COPY The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
