NATURE


Water pollution is the contamination of water bodies (e.g. lakesrivers,oceansaquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatmentto remove harmful compounds.
Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities
