Point sources of pollution The point sources of pollution are contributed at a single point in significant amount such as wastewater drain joining a water body. The point source pollution covers two major categories:Domestic pollution & Industrial pollution. Domestic Pollution Sewage is discharged into the river without any treatment from the cities located along the banks of river and its tributaries. This affects aquatic life and depletes oxygen level resulting into bad odours and turbidity. The river water does not remain suitable due to pollution, for uses like drinking, outdoor bathing, propagation of aquatic life, irrigation and industrial purposes.
Industrial Pollution Industrial pollution adissolved oxygen, temperature & pH etc. Some industrial effluents cause toxicity. Large and medium industrial units - 22 in Haryana, 42 in Delhi and 17 in Uttar Pradesh have been identified as directly discharging and polluting the river Yamuna under the Action Plan area. These industries include paper, sugar, chemical, leather, distillery and pharmaceuticals etc. These industries are contemplated to adopt adequate pollution control measures under the existing environment laws to ensure that treated effluent confirming the prescribed standards should only be discharged into the river. ffects water quality
