Data Exchange Description
The states of Oregon, Washington, Idaho, and Alaska developed the Pacific Northwest Water Quality Data Exchange to aggregate and access a comprehensive source of high-quality water data in the Pacific Northwest. Working together, the states developed XML schema to share water quality data. Each state then established a secure Network Node and began publishing the data in XML. Simple query tools retrieve information from each Node. Now, each state can query for sampling data from all states that share watersheds such as the Columbia and Snake River basins.
In November 2006, the Snohomish County (WA) Department of Public Works joined the Exchange and became the first county level organization to participate in the Exchange Network. The Samish Indian Tribe (WA) and the Stillaguamish Tribe of Indians joined the Exchange in 2008.
The most recent version of the Pacific Northwest Water Quality Data Exchange is v1.3.
