We Assess Washington's Environment

Freshwater Monitoring includes rivers, streams, and lakes, as well as the plants and animals that live there.

Puget Sound and Coastal Monitoring assesses our marine resources, including Marine Water Quality, Marine Sediments, and marine swimming beaches through the BEACH Program.

Groundwater Assessment evaluates water in the subsurface.

Stormwater Monitoring and Runoff are tested for possible pollutants, including Stormwater Monitoring for Toxics.

Soil, sediment, water, fish tissue, consumer products, and more are tested for chemicals of concern by the Toxics Studies Unit and the Marine Sediment Monitoring Team.

Air quality is tested by Ecology's Air Quality Program and Local Clean Air Agencies.

What We Learn: Data and Indicators

The Environmental Information Management system contains most of our data.

The Coastal Atlas offers map-based data and photos of Washington's coastlines and beaches.

Environmental Indicators show environmental status and trends in clear and graphic ways.

How We Work: Monitoring and Modeling

What We Measure: Parameters and Analytes describes some of the measurements made by the Environmental Assessment Program's scientists.

Our Manchester Environmental Laboratory analyzes environmental samples under rigorous protocols and quality control.

Computer Modeling uses data to picture status and trends in Washington's Environment. We offer tools and resources to assist others in modeling, as well.

We Assure Quality

Quality Assurance holds the Standard Operating Procedures for the agency.

Laboratory Accreditation is also our responsibility. Laboratory Manuals and Procedures for accreditation are available.
