The Nonpoint Source Water Pollution Program identifies non-point sources of water pollution, assess the effects of this pollution on Tribal water and aquatic resources, and works to manage this pollution and mitigate its adverse effects.

    The Tribes' Nonpoint Source Water Pollution Assessment Plan that was completed in December of 2003 has identified deficiencies in riparian buffers and instream structure as the most significant contributors to nonpoint source pollution affecting the Tribes' Ancestral Watersheds. Working with local stakeholders interested in watershed assessment and improvement projects, the program is working on systematically and naturalistically restoring Ancestral Watersheds to improve water quality for culturally-significant resources such as salmon and shellfish.

    Non-point source nutrient pollution or other water changes may increase the occurrence of harmful algae blooms (HABs) that can make shellfish toxic to consume.

    Bivalves, such as mussels and other shellfish, filter feed. The filtration process can also lead to concentration of contaminants from the water in the shellfish. Certain contaminants pose a serious health risk to humans if a contaminated shellfish is consumed. The most dangerous contaminants are paralytic shellfish toxin (PST) and Domoic Acid. These biotoxins are not destroyed by heating. In addition, events such as sewage spills and runoff during storms can contaminate shellfish making them unsafe for human consumption.
