In contrast, pollution from “nonpoint” sources is cumulative, arising from multiple inputs over larger areas, such as farms, city streets, and residential neighbourhoods. Hence, such sources are harder to precisely identify, and because of this uncertainty, nonpoint source pollution is harder to control than the point source.</u></em>
