Surface water environmental impact assessment

DefinitionSurface water: A variety of rivers exist in the landsurface (including canals, irrigation channels), lakesreservoirs and other water bodies.Waterpollution source:Anykinds of material andenergy input source which can cause harmfuleffects on water quality of the environment.Pollutant:Inputmaterial and energy
