INTRODUCTION Narmada is one of the sacred rivers of India, attracting pilgrims from all parts of the country. It Originates from Amarkantak in Shadol district, at an elevation of 1057 meter above MSL, covers distance of nearly 1312 km and total basin of 98, 796, 80 sq. km. The Narmada basin is about 1288 km. long and 80 km. broad running from east to west in Madhya Pradesh, occupies a central position in the country and empyties into the Gulf of Cambay below Broach. The Narmada river is located in Hoshangabad district of Madhya Pradesh, at latitude 22°23' 40" North and longitude 77° 58' 30" East. It flows along the Northern boundary of the district. The area of Hoshangabad district is 10,016 sq. km. topography of the district is marked by the plateau and hills of the Satpura in South all its length. The range of Satpura hills runs east to west between the Narmada river.

(Received: January 09, 2010; Accepted: February 17, 2010) ABSTRACT Narmada river water is the main source of drinking, Irrigation, fish culture and other important activities for central India. Hence the present investigations and plan of work is consisting to observe the chemical and physical constituents of Narmada River water flow. The quality of water pollution status of river. The sample collection, preservation and pre treatment according to standard method of collecting samples at international level i.e. APHA and BIS procedure. Prior to this a through survey conducted to know about probable pollution source and other relevant features. Keywords: Dissolve oxygen, BOD, COD, Turbidity, Total hardness. "Nemawar is a village in Dewas district M.P., It is 130 k.m. from Indore. Nemawar is considered as "Navel" of Narmada river" Below Nemawar to Hiran fall (also called the deer's leap) the river is surrounded by hills from both sides. In this stretch the character of the river is varied. In Madhya Pradesh out of the total catchments area of the river Narmada basin lying in the state is 85,938 sq. km. Due to urbanization and industrialization, environmental pollution is increasing day by day. The disposal of city waste, sewage and industrial effluents is becoming a major problem. The present study has been carried out to evaluate the impact of man induced environmental changes on the water quality through variation in the chemical and microbiological properties at different locations of Hoshangabad city and Nemawar village.
