Non-point source pollutants constitute a major portion of water pollution in the world. In fact, ... more Non-point source pollutants constitute a major portion of water pollution in the world. In fact, non-point source pollutants are prevalent in approximately 30 to 40 per cent of earth’s land. This in turn, would enter the food chain via farming, grazing or aquifers and cause long term health problems. Unlike points source pollution, where the effluents directly discharged into the concerned area are relatively more apparent, the sources behind non-point pollutants are unobservable and spatially distributed. These sources vary from run off chemicals used in agriculture, sewage wastes from rural houses and cities and/or effluents from factories (Corwin and Wagenet 1996; Wang et al 2012).
