Dirty Water: Environmental group lists trashiest streams around the Bay.
Vast amounts of trash — from Styrofoam cups to old tires — pollute nearly all of the streams that flow into San Francisco Bay, according to an environmental advocacy group that is pushing for new regulations to protect the region's water.
In a new report released Wednesday, Save the Bay highlighted nearly two dozen clogged streams where the environmental group says debris endangers wildlife and human health.
