Local researchers say at least 14 to 94 million pounds of contaminants like oil, grease and toxic metals get mixed with stormwater in Puget Sound every year. Now a new public-private partnership is tackling the growing problem.

The runoff from the Aurora Bridge is the target for a new project. Nonprofits like The Nature Conservancy are working together with local companies like Stephen C. Grey & Associates and Boeing to address the issue. Even the Washington State Legislature approved $500,00 to help with this project.
