Environmental Assessment Program

Quality Assurance at Ecology

The Department of Ecology relies on Quality Assurance (QA) to monitor, improve, and assess its scientific practices, especially those involving generation and assessment of environmental data. Ecology's QA system is based on requirements established by the U.S. Environmental Protection Agency and incorporates guidance and methodology from many standards-setting organizations worldwide.

Ecology uses established QA principles to plan, execute and assess all of its data-generation projects. Additionally, QA planning is often required for businesses or agencies submitting data to Ecology.
