Dog poop, lawn chemicals, and nasty spills. These are only a few of the things that stormwater picks up and mixes with as it rushes over the pavement in our driveways, sidewalks, and streets. Storm drains rush all this polluted water directly to the nearest stream, pond, or bay. No filters. No treatment. So the pollutants that stormwater carries wind up in the water we drink, fish, and swim. And that’s pretty scary. The good news is, there’s a lot we can do to keep that water clean.
