From the May 22 WDOE blog:

Clean and cool water is essential for healthy communities and thriving ecosystems, and we all have a part to play in keeping Washington’s waters clean and cool! To help guide our efforts to address widespread sources of nonpoint water pollution, Ecology is updating Washington’s Water Quality Management Plan to Control Nonpoint Sources of Pollution (Nonpoint Plan) and we invite you to be involved.

What is nonpoint source pollution?

Nonpoint pollution doesn’t come from a single pipe or facility. Instead, it comes from many sources across the landscape, like runoff from agricultural fields and parking lots, animal waste, forestry operations, and leaky septic systems. These sources can contribute to harmful levels of bacteria, nutrients, chemicals, and even high water temperatures in our streams, rivers, lakes, and coastal waters.

Nonpoint pollution is a leading cause of water quality issues in Washington – and addressing it requires a coordinated, statewide effort. Learn more about nonpoint pollution and the solutions on our nonpoint webpage.

Draft Plan Comment Period

We invite you to comment on the draft Plan to Control Nonpoint Sources of Pollution. This statewide plan outlines our strategies to address nonpoint pollution and ensures funding for us and our partners to implement clean water solutions.
