River Water and Soil Analysis in Noyyal River, Tirupur

Abstract

Tirupur is famous for its textile industries. Because of this, the rate of water pollution is also very high. The generation of waste water from the industries is the main reason for the waste water problems to the environment. Some industries are not adopting any proper treatment methods to avoid this pollution, because of the high treatment cost. Without giving proper treatment the waste water is dumping in to the river streams. By analyzing the present status of the river Noyyal, which is running through the urban centers of Tirupur city, it is clear that the river is little polluted. The rate of chemical oxygen demand (COD) and bio chemical oxygen demand (BOD) are higher than that of normal river water. This clearly indicates that the pollution is not yet controlled properly. To know the most polluted zone of river Noyyal, a case study is being processed as a project work. Both the organic and inorganic parameters are tested for each sampling point. All the parameters are varying from each sampling point to another.  Here the study analyzed the heavy metals also but they are all within the WHO limits for the drinking water usage. But the color and odour of the river Noyyal is objectionable. Hence this study also aims to know the sources of pollutants.
