What happens to the water that falls on our cities every time it rains? A lot of the answer depends on what comes in contact with that water as it runs down rooftops, over streets, through gardens, and eventually – sometimes through creeks, rivers, or lakes – into the Puget Sound. What that water picks up along the way has big implications for environmental health.
So how do we keep the Sound clean, or help make it cleaner than it is now? And what do soil and biosolids have to do with that?
