Grade Level: High School, Mathematics When it rains paved surfaces like roads, sidewalks, and parking surfaces prevent water from being absorbed into the earth. Instead, the rain water collects on the pavement’s surface and creates runoff. The problem with runoff is that it typically collects pollutants as it moves over the impenetrable surfaces creating polluted water that can be harmful to [...]
