Can we eat the fish? Where have oil spills occurred? What about toxic cleanup sites, combined sewer discharges, salmon runs and shellfish areas? Puget Soundkeeper Alliance’s interactive mapping tool allows the public to explore water quality and habitat questions throughout the Puget Sound region.

Created in partnership with Vertices, LLC of New Brunswick, NJ, the “How Clean Is Your Water?” interactive mapping tool enables users to view data related to wildlife habitats, human health, shellfish harvests, water quality, and wetlands. Each category contains a list of relevant geographical information that can be displayed across a map of Puget Sound. This allows users to identify, for example, which areas are closed for shellfish harvesting, where orcas have been sighted in recent years, which streams host strong salmon runs, and where environmental cleanup sites are located. The map incorporates Google Maps capabilities so that viewers may precisely locate areas of concern to them.

Soundkeeper hopes this tool will help residents learn about water quality issues in their part of Puget Sound.  Research from the Puget Sound Partnership suggests that a majority of people still believe that Puget Sound is healthy and does not suffer from pollution; this map locates obvious sources and areas of pollution, demonstrates why pollution prevention is important, and highlights what we may lose if we don’t succeed.  Please take some time to explore and let us know what you think!
