Physico-chemical characteristics of river Ami in relation to discharge of paper mill effluent.

The indiscriminate discharge of large volumes of highly putrescible liquid waste from the Sanjai Paper & Chemical Industries Ltd. created serious pollution problem in river Ami near Maghar town area in the district Sant Kabir Nagar of U.P., India. The river is originated from Sikahra Tal near Hallaur (Tehsil - Dumariaganj) of Siddharthnagar district U.P. and disappears into Rapti river near Kouriram of Gorakhpur district U.P. In present investigation an attempt has been made to ascertain the present water quality condition of river Ami in relation to paper mill effluent discharge. The samples were collected from the upstream and downstream of the flow-path of the river from point source of pollution by the mill. The high degree of water quality degradation is reflected by the changes in values of BOD, COD, DO, nitrogen contents and chlorides etc in downstream.
