Soundkeeper’s Clean Water Act enforcement program takes legal action against serious violators of federal water quality laws who have a record of egregious pollution to public waterways. Lawsuits are brought on behalf of Soundkeeper’s members, each of whom have a legal right to fishable, swimmable, and drinkable waterways. Soundkeeper’s goal is to achieve negotiated settlements that bring polluters into compliance with the law, and the settlement funds are then donated to local environmental groups to help restore water quality damage.

In the early 2010s, the Puget Sound Stewardship and Mitigation Fund was launched by the Rose Foundation and funded in large part by a record legal settlement between Puget Soundkeeper and Burlington Northern Santa Fe (BNSF) Railway. This fund has since been supplemented by other pollution mitigation payments – from Puget Soundkeeper and another organization called the Waste Action Project.

The Fund’s goal is to mitigate past pollution by supporting community-based efforts to protect or improve the water quality of Puget Sound. Since inception in 2012, millions of dollars in grants have been awarded for projects in Puget Sound related to conservation, restoration, citizen science, shoreline access, and environmental justice & education.
