The Problem: Urban Water Pollution

When it rains or we water our gardens, the excess water carries pollutants into the storm drains. The storm drains connect directly to local streams and lakes, ending up in Puget Sound.

Toxins from our yards, gardens and streets, like fertilizers and pesticides, bacteria from animal waste, motor oil and soap are transported into the watershed. This poisons fish and our marine ecosystem.

The good news is that individuals can do a lot to stem this pollution.
