Abstract
A study has been taken to evaluate the impact of industrial waste generated from different industries existing in Jagatpur Industrial Estate on river Mahanadi. Samples were collected from final discharge point to river Mahanadi of different industries as well as upstream and downstream of river Mahanadi to Jagatpur Industrial Estate. Samples were collected in three seasons. The results obtained at U/S and D/S points on river Mahanadi in different seasons (winter, summer and rainy) has been compared graphically. From the seasonal variation it was observed that almost all parameters are in increasing trend. In the rainy season, yearly average value at the D/S point is quite high as compared to yearly value at U/S point. The high values in rainy season is due to washing of waste dumping near Mahanadi bed. Quality Ratings for different parameters has been calculated from that water quality index was found out and compared. From the results it is concluded that, due to industrial waste discharge, water quality of river Mahanadi is deteriorated at the D/S point on river Mahanadi and the results are not meeting the prescribed standard for drinking water under Class A.
