Item Investigation of some basic water quality parameters of the north Bengal Terai river Kaljani--a tributary of river Torsa, and comparison thereof with the mainstream.(2005-04-16) Bhadra, Bhaskar; Chakraborty, Ranadhir; Das, Susanta; Nanda, Ashis KumarSome physico-chemical parameters of Kaljani River were studied in and around Alipurduar municipality. The principal characteristics of Kaljani River are high TSS, Mg-hardness, COD, and Phosphate 'P' Comparison of water quality parameters of the two rivers demonstrated higher range of alkalinity, ammonia 'N' content and chloride content in Torsa than Kaljani. River Kaljani showed higher COD range than Torsa. Mean BOD value of both these rivers ranged between 0.93-1.65 mg/l. Overall TDS content of Kaljani was found to be lower than Torsa. Maximum phosphate 'P' content was observed at the downstream of both the rivers.
