Stormwater includes rainwater runoff, snow melt, or other waters that do not soak into the ground. It flows from rooftops, over paved areas (impervious surfaces), bare soil, and through sloped lawns and greenspace. As it flows, stormwater picks up and carries soil, pet manure, salt, fertilizers, pesticides, grease and oils, leaves, litter and other pollution sources. Eventually, this water makes it into streams, rivers, and lakes with everything it picked up along the way. These materials can be harmful to the water quality of these water bodies. Stormwater drains and ditches along the roadside are meant to control the flow of stormwater and keep it from picking up too many harmful materials. Most properties contribute to stormwater runoff and everyone benefits from improved stormwater management and water quality!
