What is non-point source pollution?

Non-point source pollution are harmful substances that occur as a result of human activities over a wide area rather than from one specific location. These include forms of diffuse pollution caused by sediment, nutrients, organic and toxic substances that wash off city streets, plowed fields or other developed areas. The pollution is carried to lakes and streams by runoff.  Examples of non-point source pollution are oil and gas that leak from cars and trucks onto the pavement or over application of fertilizer on lawns or agricultural fields.
