Proper management and distribution of water have become indispensable to tackle this problem. River basin is a watershed and its management is essential to ensure the quantity and quality of its water. Study area has been underlined by Deccan Basalt lava flows. dug well and bore well samples from different parts of the Kasari River Basin have been collected and different physicochemical parameters have been analyzed to assess drinking quality of groundwater. The analysis of 42 water samples from Kasari river basin was carried for 14 parameters viz., pH, EC, TDS, TH, Ca, Mg, Na, K, CO 3 , NO 3 , HCO 3 , Cl, and SO 4 for both seasons pre and post monsoon of the year 2018. All samples have values of different parameters within permissible limit and are fit for drinking purpose.

Introduction For drinking as well as irrigation purpose the quality assessment of water is a prerequisite. Various diseases spread through the polluted water. Even irrigation done by poor quality of water; results in improper seed germination and retardation of crop affecting the yield. Also, the misuse of water and its unequal distribution are main hurdles in water management. As about 70% of Indian water resources and a growing number of its water reserves have been contaminated by biological, organic and inorganic pollutants. Analysis and study of various physicochemical parameters is essential from point of view of water quality for drinking as well as irrigation purpose. Understanding the hydrochemistry of water is vital for its optimal usage for drinking, irrigation, domestic or irrigation purpose. [4,5,11,12] STUDY AREA- The study area is Kasari River Basin. Kasari is one of the main tributaries of Panchganga River. Kasari River originates near Gajapur Village (Taluka-Shahuwadi) at Latitude 16° 39’ 51’’ to16° 55’ 13’’ N and Longitude 73° 42’ 51’’ to 74° 42’ 51’’ E. The main stream is wide and receives water from a triangular area lying between watersheds of Vishalgadh in the North and Waghjai in the South. The river receives important Southern tributary called Mangari near Bhogaon village.
