University of Technology, Gorakhpur Abstract Ami river, which is tributary of Rapti river on its right bank receives industrial effluents at several locations in a major stretch starting from Rudhauli to its confluence point at Sohgaura into Rapti river. The river water which use to be quite clear in ancient time, is presently affected severely by industrial pollution ever since the establishment of paper mill at Khalilabad, distillery and sugar unit at Rudhauli at GIDA near Sahjanwa in 1989. As the river has been the life line of the population located in the nearby villagers across its serpentine length of 126 km from Sohnara to Sogaura, it is necessary to look into the qualitative aspect of river water in time and space. With this in view a study on water quality of Ami River is attempted in this work. For this purpose water samples taken from nine sampling stations, namely Sohanara, Rudhauli, Khalilabad, Maghar, Sahjanwa (near IGL), Adilapar, Chhatai bridge, Jarlahi and Sohgaura over a period of six month from August, 2009 to February, 2010, were analyzed and the results were reviewed. The parameters included pH, Temperature, Turbidity, Electrical conductivity, Colour, Odour, Total Solids, Total Suspended Solids, Total Dissolved Solids, Dissolved Oxygen, Biochemical Oxygen Demand, Chemical Oxygen Demand, Chloride, Total Alkalinity, Oil and Grease, Total Kjeldahl Nitrogen, MPN. It is found that its entire stretch from Rudhauli to Chhatai bridge with a very little recovery up to its point of influence in Rapti river. It is also reveals that, due to critically low D.O. levels the aquatic ecosystem is severly affected from Khalilabad to Chhatai bridge. A very high organic load in terms of B.O.D. and C.O.D. is shown into the river, which results in an irreparable loss the river system. It is noticed that a very high waste load is thrown into the river at various point, which is beyond the self-purification capacity of stream and the river is not able to recover itself in a body of clean water starting from Rudhauli to its confluence into Rapti river. The most sad part of the outcome is that the river, which was in class – A ahead of its point of origin, is deteriorates so much due to industrial pollution, that it is ultimately converted into a water bodies below Class – E. the necessitates urgent step towards the restoration of water quality and regeneration of river ecosystem, which may require a coordinated effort among government agencies, industrial units, local bodies and public at large. The outcome of the study is indicative and suggested in many ways and may help in formilating the action plan towards the cleaning of river and saving it from the fury of industrial pollution. The best way of managing the problems is to stick through the same, ‘let the river remain a river’. “1. INTRODUCTION” Water is absolutely necessary for all forms of life. Because of its ubiquitous nature, the pollution of water bodies poses a potential threat to public health and aquatic ecosystems. This necessitates not only looking with the availability and consumption of water but also the qualitative aspects related therewith. It is imperative to realize the importance of water to our quality of life because; the water problem is not only confined to the quantity of water available, but also to the quality of water available. Water quality impairment is often a trigger for conflict in a watershed, simply because degraded water quality means that desired uses are not possible or not safe (Heathcote, 1998). Ami River is a meandering river which originates from Sohanara and serves as a lifeline for the people of Siddarth Nagar, Sant Kabir Nagar, Basti and Gorakhpur district in Eastern Uttar Pradesh. It travels a distance of about 126 km and drains into Rapti in Gorakhpur district of Uttar Pradesh. It has been observed that people of this region suffer from water-borne health problems; therefore water samples were collected to analyse its quality along the entire length of Ami River. The main goal of the present study was to assess the impact of urban and industrial activities on the water quality of river Ami in Eastern Uttar Pradesh. Importance of the work is to impart the knowledge and current developments in the area of water quality and its management to the field engineers 3000 International Journal of Engineering Research & Technology (IJERT) Vol. 2 Issue 12, December - 2013 ISSN: 2278-0181 www.ijert.org IJERTV2IS121237
