Abstract: Due to increase of population growth and the
of the studies identified that the major reason for the contaminations of surface water bodies due to the agricultural, domestic and industrial activities along the banks of the rivers. Acute short rainfall of monsoon rains, poor watershed management, excessive use of water for domestic and irrigation has led to the depletion of the surface water, especially from the river bodies (Babunath and John, 2017). Hence, this study was attempted to identify the surface water quality of Noyyal River basin in Coimbatore district during the study periods from December 2019 to March 2020.
increased industrial activities near the Noyyal river, resulted in the increased water pollution, which is considered as one of the primary issue of environmental pollution in metropolitan cities of developing countries including Coimbatore city in South India. The present study involves the analysis of various physico-chemical parameters of the water samples collected at ten locations in Coimbatore city along the banks of Noyyal river for various periods. From this study, it was found that the sample taken along the banks of the Noyyal river in the western part of Coimbatore city has not polluted much during the study period except at the location Kuniyamuthur. In this study, mean value of the analysed results has been identified and the relationship among the parameters was established by using correlation analysis.
2. MATERIALS AND METHODS 2.1 Study Area The present study was carried out along the banks of Noyyal river basin in Coimbatore district, Tamil Nadu, India. River Noyyal is considered as one of the major source of water for both domestic and agricultural activities for the districts of Coimbatore, Tiruppur, Erode and Karur, which has started its journey from the vellingiri hills of Western Ghats in the Coimbatore district and joins to Kaveri River at the place called Noyyal in Karur District. The River Noyyal that is originated at an elevation of about 1800 m above MSL in the pattivasal area of vellingiri hills and periyakunjira hills located in Coimbatore south. The elevation in hilly terrain in the western part of sub-basin varies from 1800 m to 600 m (above MSL) and in the eastern part 600 m to 300 m (above MSL) in the planes. The variation of elevation is due to presence of Western Ghats in the watershed. The methodology includes the collection of the surface water samples along the banks of Noyyal river basin at selected sampling locations which was listed in the Table 1. After the collection of water samples, the analysis of the collected water samples was carried out in Environmental Engineering Laboratory, Government College of Technology, Coimbatore. Periodical monitoring of the water quality parameters of the collected water samples were done for getting the average values. The average values of the water quality parameters were compared with the standard values as per Indian Standards. (Irfan Jamila and Yousuf, 2018) Finally the correlation matrix for the water quality data was generated.

1. INTRODUCTION Water is the second most basic elements for all living organisms present in the earth. It is a prime natural resource, a basic human need and precious natural asset that enables the existence and survival of life on earth. It is a limited and valuable resource. Surface water and groundwater resources are the major sources of water in our country. Large numbers of major rivers are present in India, which act as a source of major drinking water for the people of the country and irrigation purposes. Due to excessive utilization and contamination of the surface water, the need for fresh water has increased. The river beds are contributed for the withdrawal of fresh water which depends upon the monsoon seasons of the respective places and their locations. Due to uneven, non-uniform distribution and temporal variation of rainfall, the necessity is arises to store the excess water during maximum rainfall duration. It was found that, there are around 17 major rivers with 61 reservoirs were available in the state of Tamil Nadu in India for the conservation of surface water bodies. Out of the total amount of surface water around 90% of water is used for the purpose of irrigation needs. (Saranya and Sashikkumar, 2019) Most
