What is pollution control?

Pollution control goes by the technical term source control. Source control is the practice of preventing pollution at its source.

When it rains, stormwater picks up a wide variety of pollutants from surfaces such as parking lots, maintenance yards, sidewalks and streets. This polluted runoff enters the storm drain system and flows directly to our water bodies, including creeks, lakes and Puget Sound. The only way to avoid rainwater from coming into contact with these pollutants is to implement source control.

The Source Control Team at SPU has a variety of programs to help business owners, property managers and residents prevent and control pollution.

Why is source control important?

Do you eat shellfish? Do you own a boat? Do you like to swim? We are all tied to the health of Puget Sound - it is a valuable recreational resource and an economic engine for our region. Puget Sound is what makes our region so special, so let’s work together to protect it!


Source Control includes a variety of actions and programs, and we can all be involved.

The Source Control Team at SPU supports the following programs:

Other programs

The Source Control Team supports programs that are required by the National Pollutant Discharge Elimination System (NPDES) permit, administered by the Washington State Department of Ecology. These programs are just a few of the many programs that SPU and other agencies offer to support water quality and the health of Puget Sound. Other programs include:
