Assessment of water quality index of Kathani River, Gadchiroli, Maharashtra, India
Present study deserves a critical assessment of the water quality of Kathani River water, Gadchiroli, Maharashtra in terms of physico-chemical parameters and determining its water quality index. Water quality index (WQI) aims at giving a single value to the water quality of a source, reducing great amount of parameters into a simple expression. In the present investigation, water samples were collected from four sites of Kathani River, once in every month from June 2013 to May 2015 and were analyzed in the laboratory as per APHA standard methods (2012). WQI was calculated by using WHO standards of drinking Water quality and the Weighted Arithmetic Index method. The higher values of most of the hydrological parameters during rainy season had resulted the higher WQI during rainy season. The least values of WQI during winter are also supported by the magnitudes of hydrological parameters which are relatively lower during winter. The annual values of WQI of all sampling sites during study period reported the range of WQI from 56.29 to 67.77 thereby showing the overall poor water quality of Kathani River. During both the years of investigation, it was observed that the extent of pollution had increased at every site from 2013-14 to 2014-15.
