Air Quality Monitoring
This database provides near real-time air quality information to protect health. It's used to determine if air quality meets health-based federal standards.

Coastal Atlas Map
Information about Washington’s marine shorelines and the land areas near Puget Sound, the outer coast, and the estuarine portion of the Columbia River, including public access and beach closures. The Coastal Atlas includes information about:

• Beach Closures
• Flood Hazard Maps
• Public Beaches

Columbia River Mainstem - Water Resources Information System (WEBMAP)
Mapped water rights, place of use, diversions, stream flows, metering, and water right documents.

Environmental Information Management (EIM)
 Access discrete and time-series environmental data for air, water, soil, sediment, aquatic animals, and plants.

Facility/Site Identification (F/SID) System
Information on facilities and sites of interest to Ecology.

Lakes
View Washington state lake data including aquatic plants, toxic algae, herbicide use, fish management, grants and loans, and more.

Shoreline Aerial Photos
A collection of over 95,000 oblique aerial photos of Washington’s shorelines. The first set is from the 1970s and focused on Washington's 2,500 miles of marine shoreline; the most recent sets travel inland, covering the lakes and rivers of Eastern Washington.

Dirt Alert
Searchable map of areas with arsenic soil contamination from former smelters in Tacoma and Everett. Impacted areas include parts of Thurston, Pierce, King, and Snohomish counties.

A series of maps communicating spill risks and planning processes in Washington, including:  Response plans, past incidents, oil trains, facilities, equipment and more.

Water Quality Atlas
The WQ Atlas is a web based map application being developed for both Ecology staff and external users to obtain information about water quality in Washington. It will incorporate Ecology’s most significant surface water information into one searchable tool. This will include data for many of Ecology’s delegated responsibilities under the Clean Water Act: WQ standards, Assessment Waters, Permits/Outfalls, and the Improvement Project (TMDLs).

Water Rights Search
Water Rights and Wells web site that provides access through an interactive map to information maintained by the Water Resources Program within Ecology, as well as links to other water resource-related information.

Watershed Characterization
Water and habitat assessments that compare areas within a watershed for restoration and protection value. It is a coarse-scale tool that supports decisions regarding where efforts should be focused and what types of actions take at that place.

Well Report Viewer
Information on the location, ownership, construction details, and lithology of completed wells.
