Phase 1: Initial estimates
This study provided us with initial toxic chemical loading estimates for the following five of the nine main pathways:
When we added up the contributions from select chemicals of concern across all the pathways to Puget Sound, surface runoff (both river inputs and stormwater) was the dominant pathway contributing millions of pounds of toxic chemicals per year.
The eight other pathways were likely still important for particular chemicals and geographic areas.
Phase 1 also identified data gaps where we needed more information.
