As urban areas are built up, the rain falling on them runs off rooftops and paved areas into storm sewers that carry it away. Instead of falling onto open ground, where it’s filtered by soil and plants, it typically flows through the sewers directly into a nearby river or stream, carrying pollutants such as oil and chemical products along with it.
