Monitoring of Environmental Pollutants through indiscriminate disposal of untreated domestic and industrial effluent along Malir River and Chinna Creek. In this research an attempt has been pretended to dissect the conduct and the pollution index of Malir River and Chinna Creek contaminated with untreated domestic and industrial wastewater and finally dump into Arabian Sea. The primary focal point is on the quench of physical, chemical and heavy metal analysis. Almost all the parameters crossed the guidelines of National Environmental Quality Standards except pH. This indiscriminate disposal of untreated wastewater is responsible for aquatic pollution and disturbs the ecosystem.
